Description

本発明は、スピーカ取付構造に関する。 The present invention relates to a speaker mounting structure.

スピーカ装置は、中空のキャビネットの内部に取り付けられたスピーカの入力端子部に電圧を加えてコーンが振動動作を高速に繰り返すことにより空気に振動（音波）を伝達して音を発生させる。スピーカ装置においては、キャビネットの内部機構に余分な振動が伝達すると音質が濁るため、この余分な振動を誘導して接地させる必要がある。振動を誘導する構造としては、接地されたフレーム部材に全てのスピーカを固定する構造が一般的である。この構造により内部機構への振動伝達が防止され、音質低下を抑制することができる。しかし、フレーム部材自体が振動することによりスピーカの音質が濁るという新たな問題が生じるため、スピーカの音質低下の抑制には限界があった。 The speaker device applies a voltage to an input terminal portion of a speaker mounted inside a hollow cabinet, and the cone repeats a vibration operation at high speed, thereby transmitting vibration (sound wave) to the air to generate sound. In the speaker device, sound quality becomes turbid when extra vibration is transmitted to the internal mechanism of the cabinet. Therefore, it is necessary to induce the extra vibration to ground. As a structure for inducing vibration, a structure in which all speakers are fixed to a grounded frame member is generally used. With this structure, vibration transmission to the internal mechanism is prevented, and deterioration in sound quality can be suppressed. However, since the frame member itself vibrates and a new problem arises that the sound quality of the speaker becomes turbid, there is a limit to the suppression of the sound quality deterioration of the speaker.

この問題を解消すべく、上下に延びる支柱部材の上端に、スピーカとウエイトとにより釣合状態を保つ天秤部材を支承させたスピーカ取付構造が、本願出願人により提案されている（例えば、特許文献１参照。）。これによれば、スピーカの振動は天秤部材の振り子作用により吸収されるし、完全に振動が吸収されない場合は、天秤部材から支柱部材に振動が誘導される。このとき、天秤部材は支柱部材により一点で支持されるので、振動が集中的に支柱部材に誘導される。この取付構造により、スピーカの音質を大幅に向上することに成功している。
特開平１１−３５５８７６号公報 In order to solve this problem, the present applicant has proposed a speaker mounting structure in which a balance member that maintains a balanced state by a speaker and a weight is supported on the upper end of a vertically extending support member (for example, a patent document). 1). According to this, the vibration of the speaker is absorbed by the pendulum action of the balance member, and when the vibration is not completely absorbed, the vibration is induced from the balance member to the support member. At this time, since the balance member is supported at one point by the support member, vibration is intensively guided to the support member. With this mounting structure, the sound quality of the speaker has been greatly improved.

図１及び図２は本発明の第１の実施形態を示すもので、図１はスピーカ装置の縦断面図、図２はスピーカ装置の横断面図である。 1 and 2 show a first embodiment of the present invention. FIG. 1 is a longitudinal sectional view of the speaker device, and FIG. 2 is a transverse sectional view of the speaker device.

図１及び図２に示すように、このスピーカ取付構造は、同種のスピーカ２を２つ用いたスピーカ装置１に採用されている。本発明はスピーカ２を複数設けて、各スピーカ２を互いに同位相で音を出力する少なくとも一つのスピーカ群に分ける必要がある。本実施形態においては、２つのスピーカ２が同位相で音を出力する１つのスピーカ群をなす。また、本実施形態においては、各スピーカ２は、同帯域で音を出力するようになっている。図１に示すように、このスピーカ装置１は、中空の箱形状に形成された筐体としてのキャビネット３と、このキャビネット３の内部にて上下に延びる支柱部材４と、この支柱部材４の上端にて支承され各スピーカ２が固定される天秤部材５と、を具備している。 As shown in FIGS. 1 and 2, this speaker mounting structure is employed in a speaker device 1 using two of the same type of speakers 2. In the present invention, it is necessary to provide a plurality of speakers 2 and to divide each speaker 2 into at least one speaker group that outputs sound in the same phase. In the present embodiment, two speakers 2 form one speaker group that outputs sound with the same phase. In the present embodiment, each speaker 2 outputs sound in the same band. As shown in FIG. 1, the speaker device 1 includes a cabinet 3 as a housing formed in a hollow box shape, a column member 4 extending vertically within the cabinet 3, and an upper end of the column member 4. And a balance member 5 to which each speaker 2 is fixed.

また、キャビネット３の左面部６と右面部７には、スピーカ２が露出する開口８がそれぞれ形成される。この各開口８と各スピーカ２との間には、例えばゴムからなる円環形状のスピーカ用弾性部材９が介在している。また、キャビネット３は、底面部１０と、上面部と周面部からなる立設部１２とに分割構成され、底面部１０と立設部１２との間には例えばゴムからなるキャビネット用弾性部材１３が介在している。この各弾性部材９，１３は、キャビネット３内外の音響的な気密性を確保することができれば通気性があってもよい。すなわち、物理的に気密でなくともよく、例えば小さな隙間等が形成されていても、音響的な影響は無視できる程度であればよい。なお、本実施形態においては、周面部は、開口８が形成される左面部６及び右面部７に加え、前面部及び後面部を含んでいる。 Further, the left surface portion 6 and the right surface portion 7 of the cabinet 3 are each formed with an opening 8 through which the speaker 2 is exposed. Between each opening 8 and each speaker 2, an annular speaker elastic member 9 made of rubber, for example, is interposed. The cabinet 3 is divided into a bottom surface portion 10 and a standing portion 12 composed of a top surface portion and a peripheral surface portion. Between the bottom surface portion 10 and the standing portion 12, a cabinet elastic member 13 made of, for example, rubber. Is intervening. Each of the elastic members 9 and 13 may be air permeable as long as the acoustic airtightness inside and outside the cabinet 3 can be secured. In other words, it does not have to be physically airtight, and for example, even if a small gap or the like is formed, it is sufficient if the acoustic influence is negligible. In the present embodiment, the peripheral surface portion includes a front surface portion and a rear surface portion in addition to the left surface portion 6 and the right surface portion 7 where the opening 8 is formed.

支柱部材４は、底面部１０の中央部から上方に延び、上端には凹状に形成されたピボット１４が設けられる。本実施形態においては、支柱部材４は略円柱状に形成される。支柱部材４のピボット１４には、天秤部材５の支軸１５が枢着される。これにより、支柱部材４に天秤部材５が支承されることとなる。 The column member 4 extends upward from the central portion of the bottom surface portion 10 and is provided with a pivot 14 formed in a concave shape at the upper end. In this embodiment, the support | pillar member 4 is formed in a substantially cylindrical shape. A support shaft 15 of the balance member 5 is pivotally attached to the pivot 14 of the support member 4. As a result, the balance member 5 is supported on the support member 4.

天秤部材５は、略円筒形状の周壁１６と、この周壁１６の上部を閉塞する上面部１７と、この上面部１７の中央部から下方に突出形成された前述の支軸１５と、を有している。周壁１６の左部及び右部には、径方向外側へ延び各スピーカ２が固定されるブラケット１８が設けられる。本実施形態においては、各スピーカ２は、互いに同種であり、支柱部材４について対称となるよう配される。すなわち、各スピーカ２は、略同じ高さで、支柱部材４から略等距離に、左右反対となるよう設置されている。これにより、互いに同種の一群の各スピーカ２が、天秤部材５に釣合状態が保たれるよう固定されている。 The balance member 5 includes a substantially cylindrical peripheral wall 16, an upper surface portion 17 that closes an upper portion of the peripheral wall 16, and the above-described support shaft 15 that protrudes downward from the central portion of the upper surface portion 17. ing. Brackets 18 are provided on the left and right portions of the peripheral wall 16 so as to extend radially outward and to which the speakers 2 are fixed. In the present embodiment, the speakers 2 are the same type as each other and are arranged so as to be symmetric with respect to the column member 4. That is, each speaker 2 is installed so as to be opposite to the left and right at substantially the same height and at approximately the same distance from the column member 4. As a result, a group of speakers 2 of the same type are fixed to the balance member 5 so that a balanced state is maintained.

以上のように構成されたスピーカ取付構造では、スピーカ装置１の使用時に、各スピーカ２のコーン（図示せず）が比較的高速に図中左右方向の振動動作を繰り返して、空気に振動（音波）を伝達して音を発生させる。このとき、天秤部材５に設けられた一群の各スピーカ２が同位相で音を出力することとなり、各スピーカ２に生じた振動は天秤部材５にて互いに打ち消し合う方向に作用する。これにより、天秤部材５に生じる振動を飛躍的に低減することができる。 In the speaker mounting structure configured as described above, when the speaker device 1 is used, the cone (not shown) of each speaker 2 repeats a vibration operation in the left-right direction in the drawing at a relatively high speed to vibrate in the air (sound wave). ) To generate sound. At this time, a group of speakers 2 provided on the balance member 5 outputs sound in the same phase, and vibrations generated in the speakers 2 act in directions in which the balance members 5 cancel each other. Thereby, the vibration generated in the balance member 5 can be drastically reduced.

そして、各スピーカ２同士で打ち消されずに残った振動成分は、天秤部材５の支軸１５を中心とした振り子の動作により運動エネルギに変換され、この結果、天秤部材５にて吸収される。ここまでの動作により、各スピーカ２に生じた振動はほぼ完全に吸収されるが、未だ振動成分が残留している場合は、振動は支軸１５を介して支柱部材４の一点（ピボット１４）に集められ、支柱部材４に伝達されてキャビネット３の底面部１０から接地される。 The vibration component remaining without being canceled by the speakers 2 is converted into kinetic energy by the operation of the pendulum about the support shaft 15 of the balance member 5, and as a result, absorbed by the balance member 5. By the operation so far, the vibration generated in each speaker 2 is almost completely absorbed, but when the vibration component still remains, the vibration is one point (pivot 14) of the support member 4 through the support shaft 15. Are transmitted to the column member 4 and grounded from the bottom surface portion 10 of the cabinet 3.

また、キャビネット３の開口８に設けられたスピーカ用弾性部材９により、各スピーカ２からキャビネット３への振動の伝達が抑止される。さらに、底面部１０と立設部１２との間のキャビネット用弾性部材１３により、底面部１０から立設部１２への振動の伝達が抑止される。これにより、スピーカ２からの振動がキャビネット３の内部機構に伝達されることはなく、振動の伝達経路がループすることによる振動の複雑な干渉を防止することができる。 Further, the transmission of vibration from each speaker 2 to the cabinet 3 is suppressed by the speaker elastic member 9 provided in the opening 8 of the cabinet 3. Furthermore, the transmission of vibration from the bottom surface portion 10 to the standing portion 12 is suppressed by the cabinet elastic member 13 between the bottom surface portion 10 and the standing portion 12. Thereby, the vibration from the speaker 2 is not transmitted to the internal mechanism of the cabinet 3, and the complicated interference of the vibration due to the loop of the vibration transmission path can be prevented.

このように、本実施形態のスピーカ取付構造によれば、各スピーカ２を含む天秤部材５の構造系での振動を飛躍的に低減することができ、音質を飛躍的に向上させることができる。また、残った各スピーカ２の振動は天秤部材５の振り子作用により吸収され、それでも完全に振動が吸収されない場合は、天秤部材５から支柱部材４に振動が誘導される。このとき、天秤部材５は支柱部材４により一点で支持されるので、振動が集中的に支柱部材４に誘導される。すなわち、天秤部材５にスピーカ２を設けた利点を活かしつつ、音質をさらに向上することができる。 Thus, according to the speaker mounting structure of the present embodiment, vibration in the structural system of the balance member 5 including each speaker 2 can be dramatically reduced, and the sound quality can be greatly improved. Further, the remaining vibration of each speaker 2 is absorbed by the pendulum action of the balance member 5, and if the vibration is still not completely absorbed, vibration is induced from the balance member 5 to the support member 4. At this time, since the balance member 5 is supported at one point by the support member 4, vibration is intensively guided to the support member 4. That is, the sound quality can be further improved while taking advantage of the speaker 2 provided on the balance member 5.

尚、前記実施形態においては、同種のスピーカ２によりスピーカ群をなすものを示したが、異種のスピーカによりスピーカ群をなすようにしてもよい。すなわち、例えば、ボイスコイル仕様とマグネット仕様のように、各スピーカの仕様が異なっている場合であっても、各ブラケット１８を互いに異なるようにしたり、各スピーカの設置高さ、各スピーカの支柱部材４からの距離を変更したりして、スピーカ群ごとに各スピーカを釣合状態が保たれるよう天秤部材５に固定すればよい。また、各スピーカ２は同帯域で出力するものでなくてもよいことは勿論である。 In the above embodiment, the speaker group is formed by the same type of speakers 2, but the speaker group may be formed by different types of speakers. That is, for example, even when the specifications of each speaker are different, such as the voice coil specification and the magnet specification, the brackets 18 are made different from each other, the installation height of each speaker, and the support member of each speaker. What is necessary is just to fix each speaker to the balance member 5 so that a balanced state may be maintained for every speaker group by changing the distance from 4. FIG. Of course, each speaker 2 may not output in the same band.

また、前記実施形態においては、ピボット１４が凹状で支軸１５が凸状のものを示したが、例えば図３に示すように、支柱部材４に凸状の支軸２４を形成し、天秤部材５に凹状のピボット２５を形成したものであっても前記実施形態と同様の作用効果を得ることができる。 In the above embodiment, the pivot 14 has a concave shape and the support shaft 15 has a convex shape. For example, as shown in FIG. Even if the concave pivot 25 is formed in the shape 5, it is possible to obtain the same effect as that of the above embodiment.

図４は本発明の第２の実施形態を示すもので、図４はスピーカ取付構造の縦断面図である。本実施形態における第１の実施形態との主な相違点は、スピーカ２に加えてツィータ１０１を設けた点である。以下、第１の実施形態と同様の部分には同様の符号を付して、第２の実施形態について説明する。 FIG. 4 shows a second embodiment of the present invention, and FIG. 4 is a longitudinal sectional view of a speaker mounting structure. The main difference of this embodiment from the first embodiment is that a tweeter 101 is provided in addition to the speaker 2. Hereinafter, the same reference numerals are given to the same parts as those in the first embodiment, and the second embodiment will be described.

図４に示すように、第２の実施形態に係るスピーカ取付構造は、同種のスピーカ２を２つ用いるとともに、ツィータ１０１を１つ用いたスピーカ装置１００に採用されている。このスピーカ装置１００は、中空の箱形状に形成されたキャビネット１０２と、このキャビネット１０２の内部にて上下に延びる支柱部材４と、この支柱部材４の上端にて支承され各スピーカ２が固定される天秤部材５と、を具備している。天秤部材５には、各スピーカ２に加えて、ツィータ１０１が固定される。 As shown in FIG. 4, the speaker mounting structure according to the second embodiment is used in a speaker device 100 that uses two speakers 2 of the same type and one tweeter 101. The speaker device 100 includes a cabinet 102 formed in a hollow box shape, a column member 4 extending vertically within the cabinet 102, and supported by the upper end of the column member 4, and each speaker 2 is fixed. And a balance member 5. In addition to each speaker 2, a tweeter 101 is fixed to the balance member 5.

図４に示すように、キャビネット１０２の左面部１０３には、スピーカ２が露出する開口８に加えて、ツィータ１０１が露出する開口１０４が形成される。本実施形態においては、左面部１０３は、上下中央付近に上方に向かって左右内側に傾斜する傾斜部１０３ａを有している。これにより、ツィータ１０１の開口１０４は、スピーカ２の開口８に比して左右内側に形成されることとなる。各開口８と各スピーカ２との間に介在するスピーカ用弾性部材９と同様に、開口１０４とツィータ１０１との間にも、例えばゴムからなる円環形状のツィータ用弾性部材１０５が介在している。このツィータ用弾性部材１０５も、キャビネット１０２内外の音響的な気密性を確保することができれば通気性があってもよい。また、本実施形態においても、キャビネット１０２は、キャビネット用弾性部材１３を介在させて底面部１０と立設部１０６とに分割構成される。なお、支柱部材４のピボット１４に、天秤部材５の支軸１５が枢着される構成は、第１の実施形態と同様である。 As shown in FIG. 4, an opening 104 through which the tweeter 101 is exposed is formed in the left surface portion 103 of the cabinet 102 in addition to the opening 8 through which the speaker 2 is exposed. In the present embodiment, the left surface portion 103 has an inclined portion 103a that is inclined inwardly on the left and right sides in the vicinity of the upper and lower centers. Thereby, the opening 104 of the tweeter 101 is formed on the left and right inner sides as compared with the opening 8 of the speaker 2. Similar to the speaker elastic member 9 interposed between each opening 8 and each speaker 2, an annular tweeter elastic member 105 made of rubber, for example, is interposed between the opening 104 and the tweeter 101. Yes. The tweeter elastic member 105 may also be air permeable as long as the airtightness inside and outside the cabinet 102 can be secured. Also in the present embodiment, the cabinet 102 is divided into the bottom surface portion 10 and the standing portion 106 with the cabinet elastic member 13 interposed therebetween. In addition, the structure by which the spindle 15 of the balance member 5 is pivotally attached to the pivot 14 of the support | pillar member 4 is the same as that of 1st Embodiment.

天秤部材５は、第１の実施形態と同様に、略円筒形状の周壁１６と、この周壁１６の上部を閉塞する上面部１７と、この上面部１７の中央部から下方に突出形成された前述の支軸１５と、を有している。周壁１６の左部及び右部には、径方向外側へ延び各スピーカ２が固定されるブラケット１８が設けられる。天秤部材５の周壁１６における各ブラケット１８の上方にはブラケット１０７が設けられ、ツィータ１０１及びこれとバランスをとるウエイト１０８が固定される。ツィータ１０１とウエイト１０８とは、ほぼ同じ重量であり、支柱部材４について対称となるよう配される。すなわち、ツィータ１０１とウエイト１０８は、略同じ高さで、支柱部材４から略等距離に、左右反対となるよう設置されている。これにより、ツィータ１０１とウエイト１０８が、天秤部材５に釣合状態が保たれるよう固定されている。尚、第１の実施形態で述べたように、各スピーカ２は互いに同種であることから、天秤部材５は全体としてもバランスがとれた状態となっている。 As in the first embodiment, the balance member 5 includes the substantially cylindrical peripheral wall 16, the upper surface portion 17 that closes the upper portion of the peripheral wall 16, and the above-described protrusion formed downward from the central portion of the upper surface portion 17. The support shaft 15 is provided. Brackets 18 are provided on the left and right portions of the peripheral wall 16 so as to extend radially outward and to which the speakers 2 are fixed. A bracket 107 is provided above each bracket 18 on the peripheral wall 16 of the balance member 5, and a tweeter 101 and a weight 108 that balances the tweeter 101 are fixed. The tweeter 101 and the weight 108 have substantially the same weight and are arranged so as to be symmetric with respect to the support member 4. In other words, the tweeter 101 and the weight 108 are installed at substantially the same height and at the same distance from the column member 4 so as to be opposite to each other. Thereby, the tweeter 101 and the weight 108 are fixed to the balance member 5 so as to be kept in a balanced state. As described in the first embodiment, since the speakers 2 are of the same type, the balance member 5 is balanced as a whole.

以上のように構成されたスピーカ取付構造では、スピーカ装置１００の使用時に、高音部を受け持つツィータ１０１を設けたことにより、装置全体としての音質が飛躍的に向上する。このとき、各スピーカ２を対称的に設けたことによる第１の実施形態と同様の作用に加え、ツィータ１０１を天秤部材５に設けたことから、ツィータ１０１の振動成分は、天秤部材５の支軸１５を中心とした振り子の動作により運動エネルギに変換され、この結果、天秤部材５にて吸収される。この動作により、ツィータ１０１に生じた振動はほぼ完全に吸収されるが、未だ振動成分が残留している場合は、振動は支柱部材４のピボット１４に支軸１５を介して一点に集められ、支柱部材４に伝達されてキャビネット１０２の底面部１０から接地される。 In the speaker mounting structure configured as described above, when the speaker device 100 is used, the sound quality of the entire device is dramatically improved by providing the tweeter 101 that is responsible for the high-frequency part. At this time, since the tweeter 101 is provided on the balance member 5 in addition to the operation similar to that of the first embodiment by providing the speakers 2 symmetrically, the vibration component of the tweeter 101 is supported by the balance member 5. It is converted into kinetic energy by the operation of the pendulum about the shaft 15, and as a result, it is absorbed by the balance member 5. By this operation, the vibration generated in the tweeter 101 is almost completely absorbed. However, when the vibration component still remains, the vibration is collected at one point on the pivot 14 of the support member 4 via the support shaft 15. It is transmitted to the column member 4 and grounded from the bottom surface portion 10 of the cabinet 102.

また、キャビネット１０２の開口１０４に設けられたツィータ用弾性部材１０５により、ツィータ１０１からキャビネット１０２への振動の伝達が抑止される。さらに、各スピーカ２の振動と同様に、底面部１０と立設部１０６との間のキャビネット用弾性部材１３により、底面部１０から立設部１０６への振動の伝達が抑止される。これにより、ツィータ１０１からの振動がキャビネット１０２の内部機構に伝達されることはなく、振動の伝達経路がループすることによる振動の複雑な干渉を防止することができる。ここで、高音部を担当するツィータ１０１は、スピーカ２に比して音出力時の振動が少なく、天秤部材５が各スピーカ２及びツィータ１０１とともに共振したりすることはない。 Further, the transmission of vibration from the tweeter 101 to the cabinet 102 is suppressed by the tweeter elastic member 105 provided in the opening 104 of the cabinet 102. Further, like the vibration of each speaker 2, the transmission of vibration from the bottom surface portion 10 to the standing portion 106 is suppressed by the cabinet elastic member 13 between the bottom surface portion 10 and the standing portion 106. As a result, vibration from the tweeter 101 is not transmitted to the internal mechanism of the cabinet 102, and complicated interference of vibration due to looping of the vibration transmission path can be prevented. Here, the tweeter 101 in charge of the treble part has less vibration during sound output than the speaker 2, and the balance member 5 does not resonate with each speaker 2 and the tweeter 101.

このように、本実施形態のスピーカ取付構造によれば、ツィータ１０１を設け高音部の音質を向上させたスピーカ装置１００について、第１の実施形態と同様に天秤部材５における各スピーカ２の振動を飛躍的に低減しつつ、ツィータ１０１の振動をも低減して音質を向上させることができる。尚、ツィータ１０１についても、スピーカ２と同様に複数設けて、支柱部材４まわりに互いに対称となるよう配してもよい。この場合は、各ツィータ１０１の微小な振動までもが、天秤部材５にて打ち消し合うので、天秤部材５に振動が生ずることが殆どなく、さらなる音質の向上を図ることができる。 As described above, according to the speaker mounting structure of the present embodiment, the speaker device 100 provided with the tweeter 101 and improving the sound quality of the high-pitched sound portion is caused to vibrate each speaker 2 in the balance member 5 as in the first embodiment. While dramatically reducing, the vibration of the tweeter 101 can also be reduced to improve the sound quality. Note that a plurality of the tweeters 101 may be provided in the same manner as the speaker 2 and arranged so as to be symmetrical around the support member 4. In this case, even the minute vibration of each tweeter 101 is canceled by the balance member 5, so that the balance member 5 is hardly vibrated and the sound quality can be further improved.

図５は本発明の第３の実施形態を示すもので、図５はスピーカ取付構造の縦断面図である。以下、第２の実施形態と同様の部分には同様の符号を付して、第３の実施形態について説明する。 FIG. 5 shows a third embodiment of the present invention, and FIG. 5 is a longitudinal sectional view of a speaker mounting structure. Hereinafter, the same reference numerals are given to the same parts as those of the second embodiment, and the third embodiment will be described.

図５に示すように、第３の実施形態に係るスピーカ取付構造は、同種のスピーカ２を２つ用いるとともに、ツィータ１０１を１つ用いたスピーカ装置２００に採用されている。このスピーカ装置２００における第２の実施形態との主な相違点は、天秤部材５が、各スピーカ２が固定されるスピーカ用部材２０１と、ツィータ１０１及びウエイト１０８が固定されるツィータ用部材２０２と、を独立して有する点である。 As shown in FIG. 5, the speaker mounting structure according to the third embodiment is employed in a speaker device 200 that uses two speakers 2 of the same type and one tweeter 101. The main difference of the speaker device 200 from the second embodiment is that the balance member 5 includes a speaker member 201 to which each speaker 2 is fixed, and a tweeter member 202 to which the tweeter 101 and the weight 108 are fixed. , Independently.

図５に示すように、スピーカ用部材２０１は、第１の実施形態の天秤部材５と同様に、略円筒形状の周壁１６と、この周壁１６の上部を閉塞する上面部１７と、この上面部１７の中央部から下方に突出形成された前述の支軸１５と、を有している。また、スピーカ用部材２０１の上面における支軸１５の真上には、凹状に形成されたピボット２０３が設けられる。このピボット２０３には、ツィータ用部材２０２の支軸２０４が枢着される。これにより、ツィータ用部材２０２はスピーカ用部材２０１を介して支柱部材４に支承され、スピーカ用部材２０１とツィータ用部材２０２とは互いに独立して釣合状態を保つこととなる。各スピーカ２は、第１及び第２の実施形態と同様に、スピーカ用部材２０１に設けられた各ブラケット１８に固定される。 As shown in FIG. 5, the speaker member 201 includes a substantially cylindrical peripheral wall 16, an upper surface portion 17 that closes the upper portion of the peripheral wall 16, and the upper surface portion, like the balance member 5 of the first embodiment. 17 and the above-described support shaft 15 projecting downward from the central portion of the shaft 17. A pivot 203 formed in a concave shape is provided directly above the support shaft 15 on the upper surface of the speaker member 201. A pivot 204 of the tweeter member 202 is pivotally attached to the pivot 203. Accordingly, the tweeter member 202 is supported by the support member 4 via the speaker member 201, and the speaker member 201 and the tweeter member 202 are kept in a balanced state independently of each other. Each speaker 2 is fixed to each bracket 18 provided on the speaker member 201 as in the first and second embodiments.

ツィータ用部材２０２は、スピーカ用部材２０１よりも大径の略円筒形状の周壁２０５と、この周壁２０５の上部を閉塞する上面部２０６と、この上面部２０６の中央部から下方に突出形成された前述の支軸２０４と、を有している。周壁２０５は、スピーカ用部材２０１の周壁１６よりも上下方向に短く形成され、周壁１６を上部を外側から覆う。ツィータ１０１及びウエイト１０８は、第２の実施形態と同様に、ツィータ用部材２０２に設けられたブラケット１０７にそれぞれ固定される。 The tweeter member 202 is formed to have a substantially cylindrical peripheral wall 205 having a larger diameter than the speaker member 201, an upper surface portion 206 that closes an upper portion of the peripheral wall 205, and a lower portion protruding from the central portion of the upper surface portion 206. And the above-described support shaft 204. The peripheral wall 205 is formed shorter in the vertical direction than the peripheral wall 16 of the speaker member 201 and covers the upper portion of the peripheral wall 16 from the outside. The tweeter 101 and the weight 108 are respectively fixed to the bracket 107 provided on the tweeter member 202 as in the second embodiment.

以上のように構成されたスピーカ取付構造によれば、第２の実施形態のスピーカ取付構造の奏する作用効果に加え、互いにバランスを保持する各スピーカ２の群と、ツィータ１０１及びウエイト１０８の群とを別個に接地するようにしたので、装置外部で振動が生じた際にも、スピーカ用部材２０１とツィータ用部材２０２で独立して振動を効率よく減衰することができる。すなわち、電気回路に例えた際のコモンモードノイズを減少させることができ、装置が車両等のような振動系に設置される場合等に極めて有利である。 According to the speaker mounting structure configured as described above, in addition to the operational effects exhibited by the speaker mounting structure of the second embodiment, the group of speakers 2 that maintain a balance with each other, and the group of tweeters 101 and weights 108 Are separately grounded, so that vibration can be efficiently damped independently by the speaker member 201 and the tweeter member 202 even when vibration occurs outside the apparatus. That is, common mode noise when compared to an electric circuit can be reduced, which is extremely advantageous when the apparatus is installed in a vibration system such as a vehicle.

図６は本発明の第４の実施形態を示すもので、図６はスピーカ取付構造の縦断面図である。本実施形態と上述した各実施形態との主な相違点は、キャビネット３の立設部１２を支柱部材４に支承させた点と、天秤部材５の下部と支柱部材４との間に天秤用弾性部材３０４を介在させた点である。以下、第１の実施形態と同様の部分には同様の符号を付して、第４の実施形態について説明する。 FIG. 6 shows a fourth embodiment of the present invention, and FIG. 6 is a longitudinal sectional view of a speaker mounting structure. The main difference between the present embodiment and each of the embodiments described above is that the stand 12 of the cabinet 3 is supported by the support member 4 and the balance member 5 is provided between the lower part of the balance member 5 and the support member 4. The elastic member 304 is interposed. Hereinafter, the same reference numerals are given to the same parts as those in the first embodiment, and the fourth embodiment will be described.

図６に示すように、第４の実施形態に係るスピーカ取付構造は、同種のスピーカ２を２つ用いたスピーカ装置３００に採用されている。このスピーカ装置３００は、第１の実施形態と同様に、中空の箱形状に形成されたキャビネット３と、このキャビネット３の内部にて上下に延びる支柱部材４と、この支柱部材４の上端にて支承され各スピーカ２が固定される天秤部材５と、を具備している。各スピーカ２、支柱部材４は、第１の実施形態と同様の構成であるのでここでは詳述しない。 As shown in FIG. 6, the speaker mounting structure according to the fourth embodiment is adopted in a speaker device 300 using two of the same type of speakers 2. As in the first embodiment, the speaker device 300 includes a cabinet 3 formed in a hollow box shape, a column member 4 extending vertically within the cabinet 3, and an upper end of the column member 4. And a balance member 5 to which each speaker 2 is fixed. Since each speaker 2 and the support | pillar member 4 are the structures similar to 1st Embodiment, they are not explained in full detail here.

天秤部材５は、第１の実施形態と同様に、略円筒形状の周壁１６と、この周壁１６の上部を閉塞する上面部１７と、この上面部１７の中央部から下方に突出形成された前述の支軸１５と、を有している。さらに、天秤部材５の上面における支軸１５の真上には、凹状に形成されたピボット３０１が設けられる。このピボット３０１には、立設部１２の上面部３０２の略中央から下方へ突出する支軸３０３が枢着される。これにより、キャビネット３の立設部１２は天秤部材５を介して、釣合状態を保つよう支柱部材４に支承されることとなる。 As in the first embodiment, the balance member 5 includes the substantially cylindrical peripheral wall 16, the upper surface portion 17 that closes the upper portion of the peripheral wall 16, and the above-described protrusion formed downward from the central portion of the upper surface portion 17. The support shaft 15 is provided. Further, a pivot 301 formed in a concave shape is provided immediately above the support shaft 15 on the upper surface of the balance member 5. A pivot 303 is pivotally attached to the pivot 301 so as to protrude downward from the approximate center of the upper surface portion 302 of the standing portion 12. Thereby, the standing part 12 of the cabinet 3 is supported by the support | pillar member 4 through the balance member 5 so that a balanced state may be maintained.

これにより、第１の実施形態のスピーカ取付構造が奏する作用効果に加え、立設部１２に伝達される振動も振り子作用により運動エネルギに変換して吸収される。そして、振り子作用により完全に吸収されない場合は、振動は支軸３０３、ピボット３０１、支軸１５を介して支柱部材４の一点（ピボット１４）に集められ、支柱部材４に伝達されてキャビネット３の底面部１０から接地される。従って、第１の実施形態に比して、より効率的な振動の吸収を実現することができる。 Thereby, in addition to the effect which the speaker mounting structure of 1st Embodiment has, the vibration transmitted to the standing part 12 is converted into kinetic energy and absorbed by the pendulum action. If the vibration is not completely absorbed by the pendulum action, the vibration is collected at one point (pivot 14) of the support member 4 via the support shaft 303, the pivot 301, and the support shaft 15, and transmitted to the support member 4 to be transmitted to the cabinet 3. Grounded from the bottom 10. Therefore, more efficient vibration absorption can be realized as compared with the first embodiment.

また、天秤部材５の周壁１６の下部内面と支柱部材４との間には、例えばゴムからなる天秤用弾性部材３０４が介在している。この天秤用弾性部材３０４は略円環状に形成され、天秤部材５の傾倒を抑制する。すなわち、天秤用弾性部材３０４により天秤部材５における各スピーカ２の振動が吸収され、これによっても、第１の実施形態に比して効率的な振動の吸収が実現される。尚、この天秤用弾性部材３０４は略円環形状に限定されるものでないことは勿論である。 Further, a balance elastic member 304 made of rubber, for example, is interposed between the lower inner surface of the peripheral wall 16 of the balance member 5 and the support member 4. This elastic member 304 for balance is formed in a substantially annular shape, and suppresses tilting of the balance member 5. That is, the vibration of each speaker 2 in the balance member 5 is absorbed by the elastic member 304 for the balance, and this also realizes efficient absorption of vibration compared to the first embodiment. Of course, the balance elastic member 304 is not limited to a substantially annular shape.

図７及び図８は本発明の第５の実施形態を示すもので、図７はスピーカ装置の縦断面図、図８はスピーカ装置の横断面図である。以下、第１の実施形態と同様の部分には同様の符号を付して、第５の実施形態について説明する。 7 and 8 show a fifth embodiment of the present invention. FIG. 7 is a longitudinal sectional view of the speaker device, and FIG. 8 is a transverse sectional view of the speaker device. Hereinafter, the same reference numerals are given to the same parts as those in the first embodiment, and the fifth embodiment will be described.

図７に示すように、このスピーカ取付構造は、同種の２つのスピーカ２からなる第１群と、同種の２つのスピーカ４０１からなる第２群の、２群のスピーカ２，４０１を用いたスピーカ装置４００に採用されている。このスピーカ装置４００は、第１の実施形態と同様に、中空の箱形状に形成されたキャビネット３と、このキャビネット３の内部にて上下に延びる支柱部材４と、この支柱部材４の上端にて支承され各スピーカ２，４０１が固定される天秤部材５と、を具備している。天秤部材５は、第１の実施形態と同様に、略円筒形状の周壁１６と、この周壁１６の上部を閉塞する上面部１７と、この上面部１７の中央部から下方に突出形成された前述の支軸１５と、を有している。 As shown in FIG. 7, this speaker mounting structure is a speaker using two groups of speakers 2, 401, a first group consisting of two speakers 2 of the same type and a second group consisting of two speakers 401 of the same type. It is employed in the device 400. As in the first embodiment, the speaker device 400 includes a cabinet 3 formed in a hollow box shape, a column member 4 extending vertically inside the cabinet 3, and an upper end of the column member 4. And a balance member 5 on which the speakers 2 and 401 are fixed. As in the first embodiment, the balance member 5 includes the substantially cylindrical peripheral wall 16, the upper surface portion 17 that closes the upper portion of the peripheral wall 16, and the above-described protrusion formed downward from the central portion of the upper surface portion 17. The support shaft 15 is provided.

第２群の各スピーカ４０１は、第１群の各スピーカ２の上方に配される。第１群の各スピーカ２は、第１の実施形態と同様に、それぞれブラケット１８により天秤部材５に固定される。すなわち、第１群の各スピーカ２は、略同じ高さで、支柱部材４から略等距離に、左右反対となるよう設置されている。これにより、互いに同種の第１群の各スピーカ２が、天秤部材５に釣合状態が保たれるよう固定されている。 Each speaker 401 in the second group is disposed above each speaker 2 in the first group. Each speaker 2 of the first group is fixed to the balance member 5 by a bracket 18 as in the first embodiment. That is, the speakers 2 of the first group are installed at substantially the same height and at approximately the same distance from the column member 4 so as to be opposite to the left and right. As a result, the first group of speakers 2 of the same type are fixed to the balance member 5 so that a balanced state is maintained.

また、第２群の各スピーカ４０１は、天秤部材５の周壁１６の左部及び右部に設けられたブラケット４０２に固定される。各ブラケット４０２は、第１群の各スピーカ２用の各ブラケット１８の上方に配される。図８に示すように、第２群の各スピーカ２もまた、第１群と同様に、略同じ高さで、支柱部材４から略等距離に、左右反対となるよう設置されている。これにより、互いに同種の第２群の各スピーカ４０１が、天秤部材５に釣合状態が保たれるよう固定されている。すなわち、各群ごとに釣合状態が保たれることから、天秤部材５は全体としてもバランスがとれた状態となっている。 Each speaker 401 of the second group is fixed to brackets 402 provided on the left and right portions of the peripheral wall 16 of the balance member 5. Each bracket 402 is arranged above each bracket 18 for each speaker 2 of the first group. As shown in FIG. 8, each speaker 2 in the second group is also installed so as to be opposite to the left and right at substantially the same height and at approximately the same distance from the column member 4, as in the first group. As a result, the second group of speakers 401 of the same type are fixed to the balance member 5 so as to maintain a balanced state. That is, since the balanced state is maintained for each group, the balance member 5 is in a balanced state as a whole.

また、キャビネット３の左面部６及び右面部７には、第１群の各スピーカ２に対応する開口８と、第２群の各スピーカ４０１に対応する開口４０３とが形成される。第１群に対応する各スピーカ２と各開口８との間には、例えばゴムからなる円環形状のスピーカ用弾性部材９が介在し、第２群に対応する各スピーカ４０１と各開口４０３との間には、例えばゴムからなる円環形状のスピーカ用弾性部材４０４が介在する。 In addition, an opening 8 corresponding to each speaker 2 in the first group and an opening 403 corresponding to each speaker 401 in the second group are formed in the left surface portion 6 and the right surface portion 7 of the cabinet 3. Between each speaker 2 corresponding to the first group and each opening 8, an annular speaker elastic member 9 made of rubber, for example, is interposed, and each speaker 401 and each opening 403 corresponding to the second group. An annular elastic member 404 for speaker made of rubber, for example, is interposed between the two.

以上のように構成されたスピーカ取付構造によれば、天秤部材５に設けられた各スピーカ２，４０１は、各群ごとにスピーカ２，４０１が同位相で音を出力することとなり、各スピーカ２，４０１に生じた振動は天秤部材５にて互いに打ち消し合う方向に作用する。これにより、天秤部材５に生じる振動を飛躍的に低減することができる。 According to the speaker mounting structure configured as described above, the speakers 2 and 401 provided on the balance member 5 output sound in the same phase for each group. , 401 act in directions in which the balance member 5 cancels each other. Thereby, the vibration generated in the balance member 5 can be drastically reduced.

そして、各スピーカ２，４０１同士で打ち消されずに残った振動成分は、天秤部材５の支軸１５を中心とした振り子の動作により運動エネルギに変換され、この結果、天秤部材５にて吸収される。ここまでの動作により、各スピーカ２，４０１に生じた振動はほぼ完全に吸収されるが、未だ振動成分が残留している場合は、振動は支軸１５を介して支柱部材４の一点（ピボット１４）に集められ、支柱部材４に伝達されてキャビネット３の底面部１０から接地される。 The vibration component remaining without being canceled by the speakers 2 and 401 is converted into kinetic energy by the operation of the pendulum about the support shaft 15 of the balance member 5, and as a result, absorbed by the balance member 5. . By the operation so far, the vibration generated in each of the speakers 2 and 401 is almost completely absorbed. However, when the vibration component still remains, the vibration is transmitted to one point (pivot) of the column member 4 via the support shaft 15. 14), transmitted to the column member 4 and grounded from the bottom surface 10 of the cabinet 3.

また、キャビネット３の開口８，４０３に設けられたスピーカ用弾性部材９，４０４により、各スピーカ２，４０１からキャビネット３への振動の伝達が抑止される。さらに、底面部１０と立設部１２との間のキャビネット用弾性部材１３により、底面部１０から立設部１２への振動の伝達が抑止される。これにより、スピーカ２，４０１からの振動がキャビネット３の内部機構に伝達されることはなく、振動の伝達経路がループすることによる振動の複雑な干渉を防止することができる。 Further, the transmission of vibration from each speaker 2, 401 to the cabinet 3 is suppressed by the speaker elastic members 9, 404 provided in the openings 8, 403 of the cabinet 3. Furthermore, the transmission of vibration from the bottom surface portion 10 to the standing portion 12 is suppressed by the cabinet elastic member 13 between the bottom surface portion 10 and the standing portion 12. As a result, vibrations from the speakers 2 and 401 are not transmitted to the internal mechanism of the cabinet 3, and complex interference of vibrations due to looping of the vibration transmission path can be prevented.

このように、本実施形態のスピーカ取付構造によれば、複数群のスピーカ２，４０１を含む天秤部材５の構造系での振動を飛躍的に低減することができ、音質を飛躍的に向上させることができる。すなわち、複数群のスピーカ２，４０１が取り付けられる場合であっても、天秤部材５にスピーカ２を設けた利点を活かしつつ、音質をさらに向上することができる。尚、本実施形態においては、２つのスピーカ群であるものを示したが、３以上のスピーカ群であっても同様の作用効果を得ることができる。 Thus, according to the speaker mounting structure of the present embodiment, vibrations in the structural system of the balance member 5 including the plural groups of speakers 2 and 401 can be dramatically reduced, and the sound quality can be greatly improved. be able to. That is, even when a plurality of speakers 2 and 401 are attached, the sound quality can be further improved while taking advantage of the speaker 2 provided on the balance member 5. In the present embodiment, two speaker groups are shown, but the same effect can be obtained even with three or more speaker groups.

図９及び図１０は本発明の第６の実施形態を示すもので、図９はスピーカ装置の縦断面図、図１０はスピーカ装置の横断面図である。以下、第１の実施形態と同様の部分には同様の符号を付して、第６の実施形態について説明する。 9 and 10 show a sixth embodiment of the present invention. FIG. 9 is a longitudinal sectional view of the speaker device, and FIG. 10 is a transverse sectional view of the speaker device. Hereinafter, the same reference numerals are given to the same parts as those in the first embodiment, and the sixth embodiment will be described.

図１０に示すように、このスピーカ取付構造は、同種の４つのスピーカ２を用いたスピーカ装置５００に採用されている。図９に示すように、このスピーカ装置５００は、第１の実施形態と同様に、中空の箱形状に形成されたキャビネット３と、このキャビネット３の内部にて上下に延びる支柱部材４と、この支柱部材４の上端にて支承され各スピーカ２が固定される天秤部材５と、を具備している。天秤部材５は、第１の実施形態と同様に、略円筒形状の周壁１６と、この周壁１６の上部を閉塞する上面部１７と、この上面部１７の中央部から下方に突出形成された前述の支軸１５と、を有している。 As shown in FIG. 10, this speaker mounting structure is employed in a speaker device 500 using the same type of four speakers 2. As shown in FIG. 9, the speaker device 500 includes a cabinet 3 formed in a hollow box shape, a column member 4 extending up and down inside the cabinet 3, as in the first embodiment, And a balance member 5 that is supported at the upper end of the column member 4 and to which each speaker 2 is fixed. As in the first embodiment, the balance member 5 includes the substantially cylindrical peripheral wall 16, the upper surface portion 17 that closes the upper portion of the peripheral wall 16, and the above-described protrusion formed downward from the central portion of the upper surface portion 17. The support shaft 15 is provided.

図９及び図１０に示すように、各スピーカ２は、略同じ高さで、支柱部材４から略等距離に、左右左右に対称となるように、ブラケット１８を介して設置されている。これにより、互いに同種の各スピーカ２が、天秤部材５に釣合状態が保たれるよう固定されている。本実施形態においては、キャビネット３には、左面部６及び右面部７に加え、前面部５０２及び後面部５０３にも開口８が形成され、全スピーカ２がキャビネット３の外側に露出するようになっている。また、各開口８と各スピーカ２との間には、例えばゴムからなるスピーカ用弾性部材９が介在している。 As shown in FIGS. 9 and 10, the speakers 2 are installed through brackets 18 so as to be symmetrical at the left, right, left, and right at substantially the same height and at substantially the same distance from the column member 4. As a result, the speakers 2 of the same type are fixed to the balance member 5 so that a balanced state is maintained. In the present embodiment, the cabinet 3 is provided with openings 8 in the front surface portion 502 and the rear surface portion 503 in addition to the left surface portion 6 and the right surface portion 7 so that all the speakers 2 are exposed to the outside of the cabinet 3. ing. Further, between each opening 8 and each speaker 2, an elastic member 9 for speaker made of rubber, for example, is interposed.

以上のように構成されたスピーカ取付構造によれば、天秤部材５に設けられた各スピーカ２が同位相で音を出力するので、各スピーカ２に生じた振動は天秤部材５にて互いに打ち消し合う方向に作用する。これにより、天秤部材５に生じる振動を飛躍的に低減することができる。天秤部材５の振り子作用による振動の吸収作用と、支柱部材４のピボット１４への接地作用については、第１の実施形態と同様であるので、ここでは説明を省略する。 According to the speaker mounting structure configured as described above, each speaker 2 provided on the balance member 5 outputs sound in the same phase, so that the vibrations generated in each speaker 2 cancel each other out by the balance member 5. Acts on direction. Thereby, the vibration generated in the balance member 5 can be drastically reduced. Since the vibration absorbing action by the pendulum action of the balance member 5 and the grounding action of the support member 4 to the pivot 14 are the same as those in the first embodiment, the description thereof is omitted here.

このように、複数の同種のスピーカ２を支柱部材４について互いに対称に配することにより、天秤部材５におけるスピーカ２に起因する振動を低減して、音質の向上を図ることができる。尚、本実施形態においては、スピーカ２が１群であるものを示したが、例えば第５の実施形態のように２群以上のスピーカを用いたものであってもよいことは勿論である。 In this way, by arranging a plurality of the same type of speakers 2 symmetrically with respect to the support member 4, vibration due to the speakers 2 in the balance member 5 can be reduced, and sound quality can be improved. In the present embodiment, the speaker 2 is shown as one group, but it is a matter of course that two or more speakers may be used as in the fifth embodiment, for example.

図１１及び図１２は本発明の第７の実施形態を示すもので、図１１はスピーカ装置の横断面図、図１２のＡ−Ｏ−Ａ断面図である。以下、第１の実施形態と同様の部分には同様の符号を付して、第７の実施形態について説明する。 11 and 12 show a seventh embodiment of the present invention. FIG. 11 is a cross-sectional view of the speaker device, and a cross-sectional view taken along the line A-O-A in FIG. Hereinafter, the same reference numerals are given to the same parts as those in the first embodiment, and the seventh embodiment will be described.

図１１に示すように、このスピーカ取付構造は、同種の３つのスピーカ２を用いたスピーカ装置６００に採用されている。このスピーカ装置６００は、キャビネット６０１が六角筒状に形成される。本実施形態においては、キャビネット６０１は、スピーカ２を露出させる開口８が形成される３つの第１側面６０２と、第１側面６０２よりも幅方向寸法が小さい３つの第２側面６０３と、を互い違いに有している。本実施形態においても、キャビネット６０１は、キャビネット用弾性部材６０４を介在させて分割構成された底面部６０５と立設部６０６と、を有している。 As shown in FIG. 11, this speaker mounting structure is employed in a speaker device 600 that uses three speakers 2 of the same type. In the speaker device 600, a cabinet 601 is formed in a hexagonal cylindrical shape. In the present embodiment, the cabinet 601 alternates between three first side surfaces 602 in which the openings 8 that expose the speakers 2 are formed and three second side surfaces 603 that are smaller in the width direction than the first side surfaces 602. Have. Also in this embodiment, the cabinet 601 has a bottom surface portion 605 and a standing portion 606 that are divided and configured with a cabinet elastic member 604 interposed therebetween.

また、スピーカ装置６００は、キャビネット６０１の内部にて上下に延びる支柱部材４と、この支柱部材４の上端にて支承され各スピーカ２が固定される天秤部材５と、を具備している。天秤部材５は、第１の実施形態と同様に、略円筒形状の周壁１６と、この周壁１６の上部を閉塞する上面部１７と、この上面部１７の中央部から下方に突出形成された前述の支軸１５と、を有している。 The speaker device 600 includes a column member 4 that extends vertically inside the cabinet 601 and a balance member 5 that is supported at the upper end of the column member 4 and to which the speakers 2 are fixed. As in the first embodiment, the balance member 5 includes the substantially cylindrical peripheral wall 16, the upper surface portion 17 that closes the upper portion of the peripheral wall 16, and the above-described protrusion formed downward from the central portion of the upper surface portion 17. The support shaft 15 is provided.

図１１及び図１２に示すように、第１の実施形態と同様にして、各スピーカ２はブラケット１８を介して支柱部材４に固定される。本実施形態においては、各スピーカ２は、略同じ高さで、支柱部材４から略等距離に、約１２０°の間隔で設置されている（図１１参照）。これにより、互いに同種の各スピーカ２が、天秤部材５に釣合状態が保たれるよう固定されている。また、各開口８と各スピーカ２との間には、例えばゴムからなるスピーカ用弾性部材９が介在している。 As shown in FIGS. 11 and 12, each speaker 2 is fixed to the column member 4 via a bracket 18 in the same manner as in the first embodiment. In the present embodiment, the speakers 2 are installed at approximately the same height and approximately equidistant from the column member 4 at intervals of approximately 120 ° (see FIG. 11). As a result, the speakers 2 of the same type are fixed to the balance member 5 so that a balanced state is maintained. Further, between each opening 8 and each speaker 2, an elastic member 9 for speaker made of rubber, for example, is interposed.

以上のように構成されたスピーカ取付構造によれば、天秤部材５に設けられた各スピーカ２が同位相で音を出力するので、各スピーカ２に生じた振動は天秤部材５にて互いに打ち消し合う方向に作用する。このように、各スピーカ２が奇数個でキャビネット６０１が箱形形状でない場合であっても、各スピーカ２を支柱部材４について互いに対称となるよう配することにより、天秤部材５に生じる振動を飛躍的に低減することができる。また、天秤部材５の振り子作用による振動の吸収作用と、支柱部材４のピボット１４への接地作用については、第１の実施形態と同様であるので、ここでは説明を省略する。尚、本実施形態においては、スピーカ２が１群であるものを示したが、例えば第５の実施形態のように２群以上のスピーカを用いたものであってもよいことは勿論である。 According to the speaker mounting structure configured as described above, each speaker 2 provided on the balance member 5 outputs sound in the same phase, so that the vibrations generated in each speaker 2 cancel each other out by the balance member 5. Acts on direction. As described above, even when the number of the speakers 2 is odd and the cabinet 601 is not box-shaped, the vibrations generated in the balance member 5 are greatly increased by arranging the speakers 2 so as to be symmetrical with respect to the support member 4. Can be reduced. Further, since the vibration absorbing action by the pendulum action of the balance member 5 and the grounding action of the support member 4 to the pivot 14 are the same as those in the first embodiment, the description thereof is omitted here. In the present embodiment, the speaker 2 is shown as one group, but it is a matter of course that two or more speakers may be used as in the fifth embodiment, for example.

図１３及び図１４は本発明の第８の実施形態を示すもので、図１３はスピーカ装置の横断面図、図１４は図１３のＢ−Ｂ断面図である。本実施形態における各実施形態との主な相違点は、支柱部材７０１を一対設けて、各支柱部材７０１に架設される軸支部７０２を天秤部材７０３に形成した点である。以下、第１の実施形態と同様の部分には同様の符号を付して、第８の実施形態について説明する。 13 and 14 show an eighth embodiment of the present invention. FIG. 13 is a cross-sectional view of the speaker device, and FIG. 14 is a cross-sectional view taken along line BB in FIG. The main difference between the present embodiment and each of the embodiments is that a pair of support members 701 are provided and a shaft support portion 702 that is installed on each support member 701 is formed on the balance member 703. Hereinafter, the same reference numerals are given to the same parts as those of the first embodiment, and the eighth embodiment will be described.

図１３に示すように、このスピーカ取付構造は、同種の２つのスピーカ２を用いたスピーカ装置７００に採用されている。図１４に示すように、このスピーカ装置７００は、第１の実施形態と同様に、中空の箱形状に形成されたキャビネット３を具備している。キャビネット３内には、上下に延びる２つの支柱部材７０１が前後対称に設けられる。本実施形態においては、各支柱部材７０１は左右に延びる板状に形成され、上端の中央に下方へ凹の凹部７０４が形成される。図１３に示すように、各凹部７０４には、前後に延びる軸支部７０２が架設される。軸支部７０２の左右両端は断面が下方へ凸の三角形状に形成されており、この凸部分７０５が凹部７０４と係合することにより、天秤部材５は側面視にて一点で支承されることとなる。尚、軸支部７０２の前後中央側は断面が円形状に形成されている。 As shown in FIG. 13, this speaker mounting structure is employed in a speaker device 700 that uses two speakers 2 of the same type. As shown in FIG. 14, the speaker device 700 includes a cabinet 3 formed in a hollow box shape as in the first embodiment. In the cabinet 3, two support columns 701 extending vertically are provided symmetrically. In this embodiment, each column member 701 is formed in a plate shape extending left and right, and a concave portion 704 that is recessed downward is formed in the center of the upper end. As shown in FIG. 13, each recess 704 is provided with a shaft support 702 extending in the front-rear direction. The left and right ends of the shaft support portion 702 are formed in a triangular shape with a cross section projecting downward, and when the convex portion 705 engages with the concave portion 704, the balance member 5 is supported at one point in a side view. Become. In addition, the cross section is formed circularly in the front-rear center side of the shaft support portion 702.

天秤部材７０３は、第１の実施形態と同様に、略円筒形状の周壁１６と、この周壁１６の上部を閉塞する上面部１７と、を有する。そして、軸支部７０２は周壁１６の上部を貫通するように形成されている。各スピーカ２は、第１の実施形態と同様に、互いに前後対称となるようにそれぞれブラケット１８を介して周壁１６に固定される。 As in the first embodiment, the balance member 703 includes a substantially cylindrical peripheral wall 16 and an upper surface portion 17 that closes an upper portion of the peripheral wall 16. The shaft support 702 is formed so as to penetrate the upper part of the peripheral wall 16. As in the first embodiment, each speaker 2 is fixed to the peripheral wall 16 via a bracket 18 so as to be symmetrical with respect to each other.

以上のように構成されたスピーカ取付構造によれば、天秤部材７０３は、前後に延びる軸支部７０２を中心として左右方向にのみ傾動し、前後方向の傾動は規制されることとなる。これにより、各スピーカ２の左右方向の振動は、天秤部材５にて互いに打ち消し合う。打ち消されずに残った振動は前述の振り子作用により吸収され、それでも残留した振動は各支柱部材７０１から底面部１０を介して接地される。ここで、音出力時に各スピーカ２のコーンが左右方向へ振動動作をすることから、各スピーカ２に生じる振動成分の殆どは左右方向成分である。すなわち、本実施形態においては、天秤部材７０３によって各スピーカ２の振動をほぼ吸収することができるし、天秤部材７０３の前後方向の傾動が規制されることから天秤部材７０３及び各スピーカ２の安定性を確保することができる。尚、本実施形態においては、スピーカ２が１群であるものを示したが、例えば第５の実施形態のように２群以上のスピーカを用いたものであってもよいことは勿論である。 According to the speaker mounting structure configured as described above, the balance member 703 tilts only in the left-right direction around the shaft support portion 702 extending in the front-rear direction, and the tilt in the front-rear direction is restricted. Thereby, the left and right vibrations of the speakers 2 cancel each other out at the balance member 5. The vibration remaining without being canceled is absorbed by the above-described pendulum action, and the remaining vibration is grounded from each column member 701 through the bottom surface portion 10. Here, since the cone of each speaker 2 vibrates in the left-right direction during sound output, most of the vibration components generated in each speaker 2 are left-right direction components. In other words, in the present embodiment, the balance member 703 can substantially absorb the vibration of each speaker 2, and the tilting of the balance member 703 in the front-rear direction is restricted, so that the balance member 703 and the stability of each speaker 2 are stable. Can be secured. In the present embodiment, the speaker 2 is shown as one group, but it is a matter of course that two or more speakers may be used as in the fifth embodiment, for example.

図１５及び図１６は本発明の第９の実施形態を示すもので、図１５はスピーカ装置の横断面図、図１６は図１５のＣ−Ｃ断面図である。本実施形態における各実施形態との主な相違点は、複数のスピーカ２ごとにキャビネット８０１が設けられている点である。 15 and 16 show a ninth embodiment of the present invention. FIG. 15 is a cross-sectional view of the speaker device, and FIG. 16 is a CC cross-sectional view of FIG. The main difference between the present embodiment and each embodiment is that a cabinet 801 is provided for each of the plurality of speakers 2.

図１５に示すように、このスピーカ取付構造は、同種のスピーカ２を２つ用いたスピーカ装置８００に採用されている。このスピーカ装置８００は、中空の箱形状に形成され各スピーカ２ごとにキャビネット８０１を備え、各キャビネット８０１の中間にて上下に延びる支柱部材７０１を具備している。各キャビネット８０１にはスピーカ２を露出する開口８が形成され、各スピーカ２と各開口８にはスピーカ用弾性部材９が介在している。そして、支柱部材７０１の上端にて支承される天秤部材７０３に、各キャビネット８０１及び各スピーカ２が釣合状態を保つように固定されている。本実施形態においても、支柱部材７０１は前後に２つ並設されている。 As shown in FIG. 15, this speaker mounting structure is employed in a speaker device 800 that uses two of the same type of speakers 2. The speaker device 800 is formed in a hollow box shape, includes a cabinet 801 for each speaker 2, and includes a column member 701 extending vertically in the middle of each cabinet 801. Each cabinet 801 has an opening 8 that exposes the speaker 2, and a speaker elastic member 9 is interposed between each speaker 2 and each opening 8. And each cabinet 801 and each speaker 2 are being fixed to the balance member 703 supported by the upper end of the support | pillar member 701 so that a balanced state may be maintained. Also in the present embodiment, two support members 701 are arranged in front and rear.

本実施形態においては、各支柱部材７０１、天秤部材７０３は、第８の実施形態と同様に構成されている。すなわち、図１６に示すように、各支柱部材７０１は左右に延びる板状に形成され、上端の中央に下方へ凹の凹部７０４が形成される。図１５に示すように、各凹部７０４には、前後に延びる軸支部７０２が架設される。軸支部７０２の左右両端は断面が下方へ凸の三角形状に形成されており、この凸部分７０５が凹部７０４と係合することにより、天秤部材５は側面視にて一点で支承されることとなる。尚、軸支部７０２の前後中央側は断面が円形状に形成されている。尚、本実施形態においては、各支柱部材７０１は、各キャビネット８０１等と独立して設けられた土台８０２に固定されている。 In the present embodiment, each support member 701 and the balance member 703 are configured in the same manner as in the eighth embodiment. That is, as shown in FIG. 16, each column member 701 is formed in a plate shape extending in the left-right direction, and a concave portion 704 that is recessed downward is formed in the center of the upper end. As shown in FIG. 15, each recess 704 is provided with a shaft support 702 extending in the front-rear direction. The left and right ends of the shaft support portion 702 are formed in a triangular shape with a cross section projecting downward, and when the convex portion 705 engages with the concave portion 704, the balance member 5 is supported at one point in a side view. Become. In addition, the cross section is formed circularly in the front-rear center side of the shaft support portion 702. In the present embodiment, each support member 701 is fixed to a base 802 provided independently of each cabinet 801 or the like.

天秤部材７０３には、スピーカ２が固定されるブラケット８０３が設けられる。各ブラケット８０３は、それぞれキャビネット８０１を挿通してキャビネット８０３内のスピーカ２を、キャビネット８０１ごと支持する。本実施形態においては、各スピーカ２及び各キャビネット８０１は、互いに同種であり、支柱部材４について対称となるよう配される。すなわち、各スピーカ２及び各キャビネット８０１は、略同じ高さで、各支柱部材７０１から略等距離に、左右反対となるよう設置されている。これにより、互いに同種の一群の各スピーカ２及び各キャビネット８０１が、天秤部材７０３に釣合状態が保たれるよう固定されている。 The balance member 703 is provided with a bracket 803 to which the speaker 2 is fixed. Each bracket 803 is inserted through the cabinet 801 and supports the speaker 2 in the cabinet 803 together with the cabinet 801. In the present embodiment, the speakers 2 and the cabinets 801 are of the same type and are arranged symmetrically with respect to the column member 4. That is, each speaker 2 and each cabinet 801 are installed at substantially the same height and at the same distance from each column member 701 so as to be opposite to each other. As a result, a group of speakers 2 and cabinets 801 of the same type are fixed to the balance member 703 so that a balanced state is maintained.

以上のように構成されたスピーカ取付構造では、スピーカ装置８００の使用時に、各スピーカ２のコーン（図示せず）が比較的高速に振動動作を繰り返して、空気に振動（音波）を伝達して音を発生させる。このとき、各スピーカ２ごとにキャビネット８０１により覆われているので、各スピーカ２が互いにキャビネット内で圧力的に干渉することはなく、これにより音質を向上することができる。また、各スピーカ２が同位相で音を出力することから、天秤部材７０３にて振動が打ち消される。 In the speaker mounting structure configured as described above, when the speaker device 800 is used, the cone (not shown) of each speaker 2 repeatedly vibrates at a relatively high speed to transmit vibration (sound wave) to the air. Generate sound. At this time, since each speaker 2 is covered by the cabinet 801, the speakers 2 do not interfere with each other in a pressure in the cabinet, thereby improving the sound quality. Further, since each speaker 2 outputs sound with the same phase, the balance member 703 cancels the vibration.

そして、各スピーカ２同士で打ち消されずに残った振動成分は、天秤部材７０３の軸支部７０２を中心とした振り子の動作により運動エネルギに変換され、この結果、天秤部材７０３にて吸収される。ここまでの動作により、各スピーカ２に生じた振動はほぼ完全に吸収されるが、未だ振動成分が残留している場合は、振動は軸支部７０２を介して各支柱部材７０１の一点に集められ、各支柱部材７０１に伝達されて土台８０２から接地される。 The vibration component remaining without being canceled by the speakers 2 is converted into kinetic energy by the operation of the pendulum centering on the shaft support portion 702 of the balance member 703, and as a result, absorbed by the balance member 703. By the operation so far, the vibration generated in each speaker 2 is almost completely absorbed. However, when the vibration component still remains, the vibration is collected at one point of each support member 701 through the shaft support portion 702. , Transmitted to each column member 701 and grounded from the base 802.

また、キャビネット８０１の開口８に設けられたスピーカ用弾性部材９により、各スピーカ２からキャビネット８０１への振動の伝達が抑止される。これにより、スピーカ２からの振動がキャビネット８０１の内部機構に伝達されることはなく、振動の伝達経路がループすることによる振動の複雑な干渉を防止することができる。 Further, the transmission of vibration from each speaker 2 to the cabinet 801 is suppressed by the speaker elastic member 9 provided in the opening 8 of the cabinet 801. Thereby, the vibration from the speaker 2 is not transmitted to the internal mechanism of the cabinet 801, and the complicated interference of the vibration due to the loop of the vibration transmission path can be prevented.

このように、本実施形態のスピーカ取付構造によれば、各スピーカ２を含む天秤部材７０３の構造系での振動を飛躍的に低減することができ、音質を飛躍的に向上させることができる。また、残った各スピーカ２の振動は天秤部材７０３の振り子作用により吸収され、それでも完全に振動が吸収されない場合は、天秤部材７０３から各支柱部材７０１に振動が誘導される。このとき、天秤部材７０３は各支柱部材７０１により一点で支持されるので、振動が集中的に各支柱部材７０１に誘導される。すなわち、天秤部材７０３にスピーカ２を設けた利点を活かしつつ、音質をさらに向上することができる。 Thus, according to the speaker mounting structure of the present embodiment, vibrations in the structural system of the balance member 703 including each speaker 2 can be dramatically reduced, and sound quality can be dramatically improved. Further, the remaining vibration of each speaker 2 is absorbed by the pendulum action of the balance member 703, and when the vibration is still not completely absorbed, vibration is induced from the balance member 703 to each column member 701. At this time, since the balance member 703 is supported at one point by each column member 701, vibration is intensively guided to each column member 701. That is, the sound quality can be further improved while taking advantage of the speaker 2 provided on the balance member 703.

尚、本実施形態においては、スピーカ２が２つのものを示したが、例えば第６、第７の実施形態のように、スピーカ２が３以上であってもよいことは勿論である。また、スピーカ２が１群であるものを示したが、例えば第５の実施形態のように２群以上のスピーカを用いたものであってもよい。さらには、第４の実施形態のように、天秤部材７０３と各支柱部材８０１との間に弾性部材を介在させてもよい。 In the present embodiment, two speakers 2 are shown. Of course, the number of speakers 2 may be three or more as in the sixth and seventh embodiments. Further, although the speaker 2 is shown as one group, for example, a speaker using two or more groups as in the fifth embodiment may be used. Furthermore, an elastic member may be interposed between the balance member 703 and each support member 801 as in the fourth embodiment.

また、本実施形態においても、同種のスピーカ２によりスピーカ群をなすものを示したが、異種のスピーカによりスピーカ群をなすようにしてもよい。すなわち、例えば、ボイスコイル仕様とマグネット仕様のように、各スピーカの仕様が異なっている場合であっても、各ブラケット８０３を互いに異なるようにしたり、各スピーカの設置高さ、各スピーカの各支柱部材７０１からの距離を変更したりして、スピーカ群ごとに各スピーカを釣合状態が保たれるよう天秤部材５に固定すればよい。また、各スピーカ２は同帯域で出力するものでなくてもよいことは勿論である。 Also, in the present embodiment, the speaker group is formed by the same kind of speakers 2, but the speaker group may be formed by different kinds of speakers. That is, for example, even when the specifications of each speaker are different, such as a voice coil specification and a magnet specification, the brackets 803 are made different from each other, the installation height of each speaker, and each column of each speaker. What is necessary is just to fix each speaker to the balance member 5 so that a balanced state may be maintained for every speaker group by changing the distance from the member 701. Of course, each speaker 2 may not output in the same band.
