生之小型聲音產生器。又，前述耳機10具有内藏作為將聲 音再生，而產生聲音之揚聲器單元之驅動器單元4丨的作為 殼之殼體11，更具有安裝於該殼體11，至少其前端部55可 插入至使用者外耳道之作為外耳道插入構件的耳塾50作為 第1使用例。 前述殼體11具有位於其正面側之前殼體12、結合於該 前殼體12之基部12a後側之圓錐台狀後殼體13。又，如第i 圖所示，驅動器單元41以藉前殼體12及後殼體13夾前後（第 1圖之上下）之狀態，保持於前述殼體11内。此外，驅動器 單元41係所謂動態型者，具有與在「發明背景」之項所說 明之習知耳機的驅動器單元841相同之結構。即，關於驅動 器單元41之說明，沿用習知耳機之驅動器單元841之說明。 又，封住後殼體13之後面之後面部13a係略呈平板狀之 構件，藉此，於殼體11内之驅動器單元41後方（第1圖之下 方）形成為全體圓筒狀、更詳細為組合有圓錐台及圓筒之步 狀之空間的後方空間24。該後方空間24之與驅動器單元41 相對之面係後面部13a之内面’且係與驅動器單元41之振動 201127094 板相對之平面’而如第1圖所示’亦可為梢微彎曲之曲率半 徑大的平緩曲面。此外，前述殼體u具體為由銘、鋼、銅 或該等之合金等金屬構成者，亦可為如水晶之比重較大之 硬質樹脂。 D再者，於前述後殼體13安裝有包圍一端連接於驅動器 單元41之耳機電線9卜部份”持之筒狀耳齡保持部^ 的上端。此外’該耳機線保持部15亦可為與後殼體13形成 -體者。而且’耳機電線91從耳機線保持部15之下端延伸 而出。此外，在第2圖中’為圖式顯示方便，耳機電線叫堇 描繪靠近耳麟保持部15之部份，其他之部份則省略描 緣。又，於耳機電線91之圖中未示之另一端可連接音樂^

側邊觀看，沿著軸線呈線對稱。 又，於前殼體12之圓錐部16形成有作為具排氣口之功 能之空氣調整孔的前方氣道25。該前方氣道25係形成為貫 穿圓錐部16之截面圓形之孔，將前方空間21與外部連通， 前方空間21内之空氣可排放至外部。此外，前方氣道25形 成於圓錐部16之靠近基部12a之部份、即形成於朝前方之面 之部份。亦即，前方氣道25形成為朝向前方，而可將前方 空間21内之空氣朝前方排放 此外，前方氣道25之徑為 1.2[mm]，可按驅動器單元41之性能、前方空間21之尺寸等 變更。 又，於後殼體13之圓筒狀側面部13b形成有作為具排氣 口之功能之空氣調整孔的後方氣道28，作為音質調整孔之 第1調整孔27a、第2調整孔27b及第3調整孔27c。此外，總 括說明第1調整孔27a、第2調整孔27b及第3調整孔27C時， 以音質調整孔27來說明。 前述後方氣道28係形成為貫穿後殼體13之側面部Ub 之截面圓形的孔，將後方空間24與外部連通，後方空間24 内之空氣可排放至外部。此外，後方氣道28形成為朝向側 邊，而可將後方空間24内之空氣朝側邊排放。又，後方氣 道28之徑設定成與前述前方氣道25相同，可按驅動器單元 41之性能、後方空間24之尺寸等變更。如此，藉將同一徑 之排氣口、即前方氣道25及後方氣道28配設於前方空間21 及後方空間24,可改正聲音之失真及回音，並且，可減輕 10 201127094 • 施加於驅動器單元41之振動板之負荷。 又，前述第1調整孔27a、第2調整孔27b及第3調整孔27c 係形成為貫穿後殼體13之側面部13b，朝向側邊之截面圓形 之孔，將後方空間24與外部連通，並且與後方氣道28相鄰， 且於後殼體13之同一圓周上並列配設成形成一列。又，第1 調整孔27a之徑形成為小於後方氣道28之徑，第2調整孔27匕 之徑形成為小於第1調整孔27a之徑，第3調整孔27c之徑形 成為小於第2調整孔27b之徑。另，第2調整孔27b及第3調整 孔27c之徑亦可為相同。 第1調整孔27a之徑為〇.8[mm]。藉令第1調整孔27a之徑 . 為此種值，控制以12〇〇[Hz]為中心之頻帶之聲音，可使頻 率響應更順暢，而使音質提高。又，第2調整孔27b之徑為 • 〇.4[mm]。藉令第2調整孔27b之徑為此種值，控制以200[Hz] 為中心之頻帶之聲音，可使頻率響應更順暢，而使音質提 高。再者’第3調整孔27c之徑不到〇.4[mm]。藉令第3調整 孔27c之徑為此種值，可控制低於第2調整孔27b之頻帶的聲 音’可使頻率響應更順暢，而使音質提高。 又’ €令第2 s周整孔27b與第3調整孔27c同徑，例如為2 個第2調整孔27b時，可以與為1個調整孔時不同之響應控制 以200[Hz]為中心之頻帶的聲音。 此外’在圖中所示之例中’音質調整孔27為第i調整孔 27a、苐2s周整孔27b及第3調整孔3個，音質調整孔27可為1 個或2個，亦可為4個以上。又，音質調整孔27之徑可按作 為控制對象之聲音之頻帶變更。即，為控制較低頻帶之聲 201127094 音’縮小音質調整孔27之徑即可，為控制較高頻帶之聲音， 擴大音質調整孔27之徑即可。 即’該等音質調整孔27係根據該孔之直徑，決定要控 制之音頻，根據其數，控制其特性者，係調整與聲音之開 放感相關之空氣平衡者。 再者’藉形成於後殼體13之側面部13b之後方氣道28及 3 周整孔27配置於同一圓周上，而於距離驅動器單元之 距離相同之位置配置各調整孔，可更有效地控制聲音。 又由於，收容驅動器單元4，並於其前後形成前方空間 21及後方空間24之殼體11由為比重較樹脂等大，剛性高之 材料之金屬構成，故前方空間21及後方空間24之作為音響 空間之功能佳’低音渾厚，中高音明亮。又’由於殼體11 之外形從側邊觀看，沿著軸線呈線對稱，故前方空間21及 後方空間24之形狀亦沿著軸線呈線對稱，藉此’可產生無 失真之聲音。 又，於前述插入部安裝部17藉由安裝配接益14安裝有 耳墊50。前述安裝配接器14係由與殼體11相同之材料構成 之筒狀構件，其下端插入至插入部安裝部17之内周面、即 形成於殼體聲音導孔22周面之收容凹部l7a。此外’雖亦可 藉將安裝配接器14之下端嵌入至收容凹部17a’將安裝配接 器14固定於收容凹部l7a，但以於安裝配接器14之下端及收 容凹部17a形成螺溝，藉將安裝配接器〗4之下端螺入收容凹 部17a，而將安裝配接器14固定於收容凹部i7a為佳。又， 於前述安裝配接器14形成有為前後開放之圓筒狀開口之作 12 201127094 • 為聲音導孔的配接器聲音導孔14b。該配接器聲音導孔14b 之内徑宜為與殼體聲音導孔22之内徑相等之值。 再者’前述耳墊50係軟質插入構件，由矽橡膠等軟質 之可彈性變形之材料構成，為一體成形之構件，具有嵌設 於安裝配接器14周圍之筒狀本體部51、從該本體部51之前 端朝後端斜向擴展之作為彈性變形部之傘狀部53。此外， 於本體部51之後端形成有朝内側突出之厚度厚的凸緣狀卡 合凸部52 °該卡合凸部52與形成於安裝配接器14之溝狀卡 合凹部14a卡合，而可防止耳墊5〇從安裝配接器14脫落。 該耳墊50全體呈形似香菇或傘之形狀，在其前端部 55 ’於本體部51之前端連接有傘狀部53之前端，於本體部 51之外周面與傘狀部53之内周面間形成有空洞部65。又， ’ 於本體部51之中心形成有為前後端開放之圓筒狀開口之作 為聲音導孔的墊聲音導孔61。以耳墊5〇藉由安裝配接器14 安裝於插入部安裝部17之狀態，墊聲音導孔61藉由配接器 聲音導孔14b與殼體聲音導孔22連通。 又’傘狀部53具有朝後方擴展之圓錐台狀前半部53a、 伙s亥削半部53a之後端延伸而出至後方之圓筒狀後半部 53b。伞狀部53厚度較本體部51薄，且具柔軟性 ，而可因承 爻力1，而易變形。因而，當耳墊5〇插入至外耳道之際， 伞狀部53彈性變形成適合外耳道之内面形狀，而不致對外 耳道造成損傷，且不於外耳道之内面施加反作用力而可密 合，故裝戴感、合適感等佳。 再者’於傘狀部53之前半部53a形成有從前端側觀看延 13 201127094 伸成=射狀之魏個(在圖輯之例 62。當使用者裝戴耳_時，耳㈣插人至^:開 _遮斷外耳道之内外。然而、由於存Γ 外耳道之内外連通，故即使裝戴耳機刚η之=’ 境音仍可人射科耳叙㈣，_ f 4科# Μ，由於外耳道内部之空氣通過心二=

即使形成傘狀部53變形，而被壓至本體部51之外周面之狀 態’由於開σ部62與對應其之墊溝63相互叠合，故可維持 外耳道内外之連通。 接著’就前述耳墊5〇之結構詳細說明。 第3圖係本發明實施形態之耳墊之四面圖第*圖係本 發明實施形態之耳塾之截面圖。此外，在第3圖中，（Α)係 左側面圖，（Β)係背面圖，（C)係右側面圖，（D)係正面圖。 在第4圖中’（A)係第3(B)圖之B-B箭視截面圖，（B)係第3(B) 圖之C-C箭視截面圖。 本體部51之前端與傘狀部53之前端以前端連接部54連 接，各開口部62之前端藉由連通凹部64，連通於墊聲音導 14 201127094 * - 孔61之前端。又，在耳墊50之圓周狀前端部55，前端連接 部54與連通凹部64交互配置。因此，從驅動器單元41經由 殼體聲音導孔22、配接器聲音導孔14b及墊聲音導孔61而入 射至外耳道内部之聲音由於其一部份藉由連通凹部64，從 開口部62穿透至外部，故可減低壓迫感、不清楚感等，而 明免。 此外，如第4(A)圖所示，前端連接部54厚度較傘狀部 53厚，剛性高於傘狀部53，而不易變形。又，配設成夾在 前端連接部54間之連通凹部64從側面觀看，形成為凹入至 比前端部55之前端緣、即前端連接部54之前端緣還後方。 因此’當耳墊5〇插入至外耳道之際，即使傘狀部53變形， 連通凹部64亦不致封閉，而可維持墊聲音導孔61與開口部 62之連通。此外，如前述，即使形成傘狀部53變形，不僅 被壓至本體部51之外周面，亦被壓至圓錐部丨6表面之狀 悲’開口部62及塾溝63仍可連通。因而，由於可穩定地確 保從墊聲音導孔61經由連通凹部64、開口部62及墊溝63， 至外部之聲音之通道，故可穩定地減低壓迫感、不清楚感 等，而可維持明亮之音質。 又’如第4(B)圖所示，開口部62宜形成為在其前端與 墊溝63之前端連接。此時，即使傘狀部53大幅變形，開口 部62與墊溝63之連通仍可維持穩定。 再者’如第3(D)圖所示，於傘狀部53之前半部53a形成 有從正面觀看延伸成放射狀之複數個縫隙狀開口部62。因 此’因開口部62之存在’前半部53a之剛性降低，而易變形， 15 201127094 當耳整50插入至外耳道之際，不僅前半部53a，傘狀部53全 體柔軟地彈性變形，而適合外界道之内面形狀。因而，由 於不致對外耳道造成損傷，安全性向’傘狀部部53不致於 外耳道之内面施加反作用力而"5]*密合’故裝戴感、合適感 等佳，並且可防止耳機10從耳廓脫落。 此外，在圖中所示之例中’開口部62、塾溝63及連通 凹部64之數分別為6個，未必需為6個，可為5個以下，亦可 為7個以上。 如此，由於藉於插入部安裝部17藉由安裝配接器14安 :由軟質材料構成之耳墊50,耳機10之物生增高，故適 合使用者進行步行等活動之際使用。又，如前述，由於因 ，口部62等之存在，外耳道之内外可連通故警報等外部 環境音入射至外耳道之内部，到達鼓膜，安全性不致降低， 音質亦佳。 接著，就前述耳機1〇之第2使用例作說明。 第5圖係顯示本發明實施形態之耳機之第2使用例的截

最小’越在下’外按越大。亦即，凸出部74由於其外面形 成尖細之錐面’故可易插入至外耳道。此外，凸出部7仏 最大外彳ϋ大於殼H11之插人部安裝部17上端之外徑。 又，S將耳機線保持部15及耳機電線91排除在外時， 匕3殼體11及耳塞7〇之耳機1〇之外形如第6(£)圖所示，從 前方觀看為圓形’如第6(A)圖、第6⑻圖、第6⑼圖所示， 從側邊觀看，沿著軸線呈線對稱。 再者，耳塞70之凸出部74插入至外耳道之際，按壓外 耳道之内面而使其變形，而可使外耳道内面之至少一部份 17 201127094 毪口於凸出部74之外面。此時，由於凸出部74之外面形成 大細之錐面’故當將凸出部74插人至外耳道之際可使外 耳道内面平順地變形，而不致對外耳道造成損傷，外耳道 内面對凸出部74之外面之密合性高，裝設感、合適感等佳。 再者，由於包含凸出部74之耳塞7〇由比重大，剛性高

P16 is formed such that the axis of its front end coincides with the axis of the base end. 1 'When the earphone cord holding portion 15 and the earphone cord 19 are excluded, the outer shape of the earphone 10 including the body U and the deafness 5 is as shown in the second (6) diagram, and is circular as viewed from the front 201127094, as in the second (A), 2 (B), and 2 (D) are line symmetrical along the axis as viewed from the side. Further, a front air passage 25 as an air adjusting hole having a function of an exhaust port is formed in the conical portion 16 of the front casing 12. The front air passage 25 is formed as a circular hole that penetrates the conical portion 16, and communicates the front space 21 with the outside, and the air in the front space 21 can be discharged to the outside. Further, the front air passage 25 is formed in a portion of the conical portion 16 which is close to the base portion 12a, that is, a portion which is formed on the front surface. That is, the front air passage 25 is formed to face forward, and the air in the front space 21 can be discharged toward the front. Further, the diameter of the front air passage 25 is 1.2 [mm], and the performance of the driver unit 41 and the size of the front space 21 can be selected. change. Further, a rear air passage 28 as an air adjusting hole having a function of an exhaust port is formed in the cylindrical side surface portion 13b of the rear casing 13, and the first adjustment hole 27a, the second adjustment hole 27b, and the first adjustment hole 27b as the sound quality adjusting hole are formed. 3 Adjust the hole 27c. Further, when the first adjustment hole 27a, the second adjustment hole 27b, and the third adjustment hole 27C are described in detail, the sound quality adjustment hole 27 will be described. The rear air passage 28 is formed as a circular hole having a circular cross section penetrating the side surface portion Ub of the rear casing 13, and communicates the rear space 24 with the outside, and the air in the rear space 24 can be discharged to the outside. Further, the rear air passage 28 is formed to face the side, and the air in the rear space 24 can be discharged toward the side. Further, the diameter of the rear air passage 28 is set to be the same as that of the front air passage 25, and can be changed in accordance with the performance of the driver unit 41, the size of the rear space 24, and the like. In this way, by disposing the exhaust port of the same diameter, that is, the front air passage 25 and the rear air passage 28, in the front space 21 and the rear space 24, the distortion and the echo of the sound can be corrected, and the noise can be reduced. 10 201127094 • Applied to the driver unit 41 The load of the vibrating plate. Further, the first adjustment hole 27a, the second adjustment hole 27b, and the third adjustment hole 27c are formed so as to penetrate the side surface portion 13b of the rear case 13, and have a circular hole having a circular cross section toward the side, and connect the rear space 24 to the outside. And adjacent to the rear air passage 28, and arranged side by side on the same circumference of the rear casing 13 to form a row. Further, the diameter of the first adjustment hole 27a is smaller than the diameter of the rear air passage 28, the diameter of the second adjustment hole 27 is smaller than the diameter of the first adjustment hole 27a, and the diameter of the third adjustment hole 27c is smaller than the second adjustment.

By adjusting the diameter of the first adjustment hole 27a. For this value, controlling the sound in the frequency band centered at 12 〇〇 [Hz] can make the frequency response smoother and improve the sound quality. Further, the diameter of the second adjustment hole 27b is • 〇.4 [mm]. By the diameter of the second adjustment hole 27b being such a value, the sound in the frequency band centered at 200 [Hz] is controlled, and the frequency response is made smoother, and the sound quality is improved. Further, the diameter of the third adjustment hole 27c is less than 4.4 [mm]. By the reason that the diameter of the third adjustment hole 27c is such a value, the sound of the frequency band lower than the second adjustment hole 27b can be controlled to make the frequency response smoother and the sound quality improved. In addition, the second hole 27 27b and the third adjustment hole 27c have the same diameter. For example, when the two second adjustment holes 27b are used, the response control different from the case of one adjustment hole is centered at 200 [Hz]. The sound of the band. Further, in the example shown in the figure, the sound quality adjusting hole 27 is the ith adjustment hole 27a, the 苐2s circumference hole 27b, and the third adjustment hole, and the sound quality adjustment hole 27 may be one or two. It is 4 or more. Further, the diameter of the sound quality adjusting hole 27 can be changed in accordance with the frequency band of the sound to be controlled. In other words, in order to control the sound of the lower frequency band, the sound of the sound quality adjustment hole 27 may be reduced, and the diameter of the sound quality adjustment hole 27 may be enlarged to control the sound of the higher frequency band. In other words, the sound quality adjusting holes 27 determine the audio to be controlled based on the diameter of the hole, and control the characteristics according to the number, and adjust the air balance related to the opening feeling of the sound. Furthermore, the air passage 28 and the three-hole entire hole 27 are disposed on the same circumference after being formed on the side surface portion 13b of the rear casing 13, and the adjustment holes are disposed at the same distance from the driver unit, thereby being more effectively controlled. sound. Further, since the casing 11 that houses the driver unit 4 and forms the front space 21 and the rear space 24 in the front and rear sides thereof is made of a metal having a larger specific gravity than a resin and a high rigidity, the front space 21 and the rear space 24 serve as The function of the sound space is good. 'The bass is thick and the middle and high notes are bright. Further, since the outer shape of the casing 11 is viewed from the side and is line symmetrical along the axis, the shapes of the front space 21 and the rear space 24 are also line symmetrical along the axis, whereby a sound without distortion can be generated. Further, the ear pad 50 is attached to the insertion portion mounting portion 17 by attaching the connection and receiving benefit 14. The mounting adapter 14 is a cylindrical member made of the same material as the casing 11, and its lower end is inserted into the inner peripheral surface of the insertion portion mounting portion 17, that is, the housing recess 17a formed on the circumferential surface of the housing sound guide hole 22. . In addition, the mounting adapter 14 may be fixed to the receiving recess 17a by inserting the lower end of the mounting adapter 14 into the receiving recess 17a'. However, the lower end of the mounting adapter 14 and the receiving recess 17a form a threaded groove. It is preferable that the lower end of the mounting adapter 4 is screwed into the housing recess 17a to fix the mounting adapter 14 to the housing recess i7a. Further, the mounting adapter 14 is formed with a cylindrical opening that is open to the front and rear. 12 201127094 • The adapter sound guide hole 14b is a sound guide hole. The inner diameter of the adapter sound guiding hole 14b is preferably equal to the inner diameter of the housing sound guiding hole 22. Further, the ear pad 50 is a soft insertion member, and is made of a soft elastically deformable material such as ruthenium rubber. The integrally formed member has a cylindrical body portion 51 that is fitted around the mounting adapter 14 and is The front end portion of the main body portion 51 is expanded toward the rear end to expand the umbrella portion 53 as an elastic deformation portion. Further, a flange-shaped engaging convex portion 52 having a thick thickness protruding toward the inner side is formed at the rear end of the main body portion 51. The engaging convex portion 52 is engaged with the groove-shaped engaging concave portion 14a formed in the mounting adapter 14. It is possible to prevent the ear pad 5 from coming off the mounting adapter 14. The entire ear pad 50 is shaped like a mushroom or an umbrella, and the front end portion 55' is connected to the front end of the umbrella portion 53 at the front end of the main body portion 51, and the outer peripheral surface of the main body portion 51 and the inner peripheral surface of the umbrella portion 53. A cavity portion 65 is formed therebetween. Further, a pad acoustic guide hole 61 as a sound guide hole is formed in the center of the main body portion 51 as a cylindrical opening that is open at the front and rear ends. The pad sound guiding hole 61 is in communication with the housing sound guiding hole 22 by the adapter sound guiding hole 14b in a state where the ear pad 5 is attached to the insertion portion mounting portion 17 by the mounting adapter 14. Further, the umbrella portion 53 has a truncated cone-shaped front half portion 53a that expands rearward, and a cylindrical rear half portion 53b that extends rearward from the rear half of the shaving half portion 53a. The umbrella portion 53 is thinner than the body portion 51 and has flexibility, and is easily deformed due to the bearing force 1. Therefore, when the ear pad 5 is inserted into the external auditory canal, the umbrella portion 53 is elastically deformed to conform to the inner surface shape of the external auditory canal without causing damage to the external auditory canal, and the reaction force is not applied to the inner surface of the external auditory canal, so that it can be worn. Sense, suitability, etc. Further, the front half 53a of the umbrella portion 53 is formed with a view from the front end side of the extension 13 201127094 and the extension of the shot shape (in the case of the example 62. When the user wears the ear _, the ear (four) inserts To ^: open_interrupted inside and outside the external auditory canal. However, due to the internal and external communication of the external auditory canal, even if the headset is just η = ' 境 音 can still be shot by Ke Erxu (4), _ f 4 Section # Μ, due to The air inside the external auditory canal passes through the heart 2 = two = decreases from the driver unit 41 via the housing sound guide hole 22 and the click sound: the sound of the person hitting the inside of the external auditory canal is uncomfortable, unclear, etc. Therefore, the bass The sharpness is good, and the middle and high-pitched sounds are bright. i, since the vocal shirt from the driver's singer presses the tympanic membrane, it is also good in the healthy side. The cake temple is further 'in the outer peripheral surface of the main body portion 51, and the opening portion 62 should be respectively The position is formed in the front-rear direction, that is, the surface 63 of the groove extending in the axial direction of the body. Therefore, when the ear (four) is inserted into the external auditory canal, even if the formation of the umbrella portion 53 is deformed, it is pressed to the body portion 51. The state of the outer peripheral surface 'because the opening σ portion 62 and the corresponding pad groove 63 overlap each other, The connection between the inside and the outside of the external auditory canal can be maintained. Next, the structure of the ear pad 5A will be described in detail. Fig. 3 is a four-side view of the ear pad according to the embodiment of the present invention, and is a cross-sectional view of the ear piece according to the embodiment of the present invention. In Fig. 3, (Α) is the left side view, (Β) is the rear view, (C) is the right side view, and (D) is the front view. In Fig. 4, '(A) is the third ( B) BB arrow cross-sectional view, (B) is a CC arrow cross-sectional view of the third (B) drawing. The front end of the main body portion 51 and the front end of the umbrella portion 53 are connected by a front end connecting portion 54, and each opening portion 62 The front end communicates with the pad sound guide 14 through the communication recess 64. The front end of the hole pad 50, the front end connection portion 54 and the communication recess portion 64 are alternately arranged. Therefore, the slave drive The sound of the unit 41 incident on the inside of the external auditory canal through the housing sound guiding hole 22, the adapter sound guiding hole 14b and the pad sound guiding hole 61 is penetrated from the opening portion 62 to the outside by a part of the communicating concave portion 64. Therefore, it is possible to reduce the pressure of the low pressure, the sense of unclearness, and the like. In addition, as shown in Figure 4(A), the front end is connected. The thickness of 54 is thicker than that of the umbrella portion 53, and the rigidity is higher than that of the umbrella portion 53 and is not easily deformed. Further, the communication concave portion 64 interposed between the front end connecting portions 54 is formed to be concave to the front end portion 55 as viewed from the side. The front edge, that is, the front edge of the front end connecting portion 54 is also rearward. Therefore, when the ear pad 5 is inserted into the external auditory canal, even if the umbrella portion 53 is deformed, the communicating concave portion 64 is not closed, and the pad sound guiding hole 61 can be maintained. Further, as described above, even if the formation of the umbrella portion 53 is deformed, it is pressed not only to the outer peripheral surface of the main body portion 51 but also to the surface of the conical portion 丨6, which is the opening portion 62 and the sulcus. 63 still connected. Therefore, since it is possible to stably ensure the passage from the pad sound guide hole 61 to the external sound via the communication concave portion 64, the opening portion 62, and the pad groove 63, it is possible to stably reduce the low pressure sensation, the unclear feeling, and the like, and maintain the brightness. Sound quality. Further, as shown in Fig. 4(B), the opening portion 62 is preferably formed to be connected to the front end of the pad groove 63 at the front end thereof. At this time, even if the umbrella portion 53 is largely deformed, the communication between the opening portion 62 and the pad groove 63 can be maintained stable. Further, as shown in Fig. 3(D), a plurality of slit-like openings 62 extending radially from the front are formed in the front half portion 53a of the umbrella portion 53. Therefore, the rigidity of the front half portion 53a is reduced due to the presence of the opening portion 62, and is easily deformed. 15 201127094 When the ear piece 50 is inserted into the external auditory canal, not only the front half portion 53a but also the entire umbrella portion 53 is elastically elastically deformed, and is suitable for the outside world. The inner shape of the road. Therefore, since the damage to the external auditory canal is not caused, the safety of the umbrella portion 53 does not exert a reaction force on the inner surface of the external auditory canal and the "5"* closeness is good, so that the wearing feeling and the appropriate feeling are good, and the earphone 10 can be prevented from being The auricle is detached. Further, in the example shown in the drawing, the number of the opening portion 62, the sulcus 63, and the communicating concave portion 64 is six, and it is not necessary to be six, and may be five or less, or seven or more. As described above, the insertion portion mounting portion 17 is attached to the adapter 14 by the ear pad 50 made of a soft material, and the object of the earphone 10 is increased. Therefore, it is suitable for use when the user performs an activity such as walking. Further, as described above, the presence or absence of the mouth portion 62 allows the external auditory canal to be connected to the inside and outside of the external auditory canal, and the external environmental sound such as an alarm is incident on the inside of the external auditory canal, and the tympanic membrane is reached, so that the safety is not lowered and the sound quality is also good. Next, a second use example of the above-described earphone 1 will be described. Fig. 5 is a cross-sectional view showing a second use example of the earphone according to the embodiment of the present invention.

In addition, in Fig. 6, (=) is the top view, (B) is the left side view, (c%t plan, (d) is the right side view (E) is the front view. In the second pass The earplug 7G, at least the distal end portion 75 of which can be inserted into the ear canal insertion member of the user's ear canal, is attached to the casing u. The ear soil is a rigid insertion member, and the same metal as the casing u, that is, the specific gravity 16'''''''''''''''''' The portion of the portion 71 extending to the rear of the protruding portion is a woman's W. The mounting portion of the mounting portion 7 is attached to the inner peripheral surface of the housing portion, that is, formed on the circumferential surface of the housing sound guide hole 22. The recessed portion is accommodated. In addition, the earplug 70 may be fixed to the receiving portion 72 and the receiving recess portion to form a thread by attaching the mounting portion 72 to the recessed portion. The snail is easy to carry out, and (4) the earplug side is preferably set in the accommodating recess 17a. > is formed as a sound guide hole having a cylindrical opening which is open at the front and rear ends The earphones are in contact with the guide hole 73. The ear pods are connected to the housing sound guide hole 22 in a state where the earplug 70 is attached to the insertion portion mounting portion 17. Further, the earphone sound guide hole 73 is provided. Preferably, the projection 74 has a value equal to the inner diameter of the housing sound guide hole 22. The projection 74 has a shape such as a truncated cone, and the outer diameter of the front end portion 75 is the smallest. The outer portion 74 can be easily inserted into the external auditory canal because of the tapered tapered surface on the outer side. Further, the maximum outer diameter of the protruding portion 7 is larger than the outer diameter of the upper end of the insertion portion 17 of the housing H11. When the earphone cord holding portion 15 and the earphone cord 91 are excluded, the outer casing 11 of the casing 3 and the earplug 7 is shaped as shown in Fig. 6 (£), and viewed from the front as a circle ' as in the sixth (A) Fig. 6(8) and Fig. 6(9) are line symmetrical along the axis when viewed from the side. Further, when the protruding portion 74 of the earplug 70 is inserted into the external auditory canal, the inner surface of the external auditory canal is pressed and deformed. At least a portion of the inner surface of the external auditory canal 17 201127094 can be smeared outside the projection 74. The outer surface of the protruding portion 74 forms a large tapered surface. Therefore, when the protruding portion 74 is inserted into the external auditory canal, the inner surface of the external auditory canal can be smoothly deformed without causing damage to the external auditory canal, and the convex portion 74 is faced in the external auditory canal. The outer surface has high adhesion, good mounting feeling, and the like. Further, since the earplug 7 including the protruding portion 74 is formed of a hard material having a relatively high rigidity and high rigidity, the sound from the driver unit 41 is not caused: Therefore, the sound quality is improved. Further, even if the protruding portion 74 is inserted into the external auditory canal, the earplug sound guiding hole 73 is not deformed. Therefore, since the sound from the driver unit 41 is incident on the external auditory canal under *distortion, the sound quality is improved. In the present embodiment, the earphone 10 includes at least a portion of the cannula insertion member that can be inserted into the external auditory canal, the housing 11 that can be detachably attached to the channel insertion member, and a driver that is disposed in the housing u to generate sound. The single ankle 41, the external auditory canal insertion member comprises an elastically deformable ear pad and a high rigidity earplug 70, and the ear pad 50 and the earplug 70 are selectively mounted to the housing n. Thereby, the ear pad 5A and the earplug 70 can be appropriately selected in accordance with the use condition of the earphone 1 and attached to the casing η. For example, if the wearability is emphasized when walking outside the house, the ear pad 50 is selected, and when the sound quality is emphasized when the music is appreciated indoors, the earplug 70 can be selected. Therefore, it is possible to obtain high mountability and a good wearing feeling in response to a wide range of use conditions, and to obtain horse sound quality. Further, the general body 11 has a truncated conical space 21 formed in front of the driver unit 41, and a front end of the front space 21, and the sound is incident on the housing sound guide hole 22 of the external auditory canal, and is formed at the rear of the driver unit 41. The cylindrical rear space 24 is made of metal, and the rear space 24 has a sound quality adjusting hole 27 that opens toward the side 18 201127094. In this manner, since the body unit 24 that houses the driver unit 4' and forms the front space 21 and the rear space 24 in front and rear is formed of a metal material having a high rigidity and a high rigidity, the front space 21 and the rear space 24 serve as an acoustic space. It has a good function and produces a thick bass and a bright mid-high sound with good acoustic characteristics. Moreover, the sound quality adjustment hole 27 can be appropriately controlled to appropriately control the sound of the desired frequency band, and the rear space 24 has a plane plane opposite to the driver unit 41, and the rear space 24 has an air passage 28 which is opened toward the side, and the front door is opened. 21 has a square air passage 25 before opening to the front. Thereby, the sound can be corrected and the echo can be corrected, and the negative of the vibrating plate applied to the driver unit can be reduced, and the housing 11 and the ear canal insertion member mounted outside the housing li can be moved back and forth. The axis of the direction extension is line symmetrical.辟 > The voice of truth. ..., the ear (4) has a money sound rhythm 4 5 is connected to the front end of the body portion 51 'the umbrella-shaped standing 53 extending obliquely from the front end minus the umbrella portion 53 having the front end side viewed from the body portion 51 Extending into a flared shape, the plurality of slit-shaped openings 62' have a body portion 51 having a position formed on the outer peripheral surface thereof opposite to each of the openings 62, and extending in the axial direction. When the outer peripheral surface of the main body portion 51 is pressed, the opening portion 62 overlaps with the corresponding portion 63. By the pad 4, when the ear pad 50 is inserted into the external auditory canal, even if the umbrella 53 is deformed and pressed to the outer peripheral surface of the body portion 51, the communication between the inside and the outside of the external auditory canal can be maintained. Therefore, due to an external environmental sound such as an alarm, it is incident to |b = 19 201127094.卩' arrives at the diaphragm, so safety is not reduced. Further, since the air passage σ62 inside the external auditory canal penetrates to the outside, the pressure of the sound from the earphone ίο incident inside the external auditory canal is reduced, and the sense of clarity is improved. Therefore, the low definition is good and the middle and high notes are bright. Furthermore, since the sound from the earphone (7) does not press the tympanic membrane, it is also preferable in terms of a healthy side. Further, the earplug 70 has an earplug sound guiding hole 73 formed in the center of the cylindrical body portion 71, the outer surface from the front end toward the rear end of the main body portion 71, and the convex portion 74 which is obliquely expanded, and is made of metal, and the convex portion 74 is When inserted into the external auditory canal, at least a portion of the inner surface of the external auditory canal is deformed. Therefore, the sense of installation and the sense of fit are good, and the clarity of the bass is good, and the middle and high notes are bright. Further, since the earplug sound guiding hole 73 is not deformed even if the protruding portion 74 is inserted into the external auditory canal, the sound from the driver unit 41 is incident on the external auditory canal without distortion, and the sound quality is good. Further, the present invention is not limited to the foregoing embodiments, and various modifications may be made without departing from the scope of the invention. Industrial Applicability The present invention is applicable to an earphone having at least a portion of an ear canal insertion member that can be inserted outside the external auditory canal.
