Further, by inserting the terminal into the terminal insertion port, a portion corresponding to the speaker provided in the terminal is brought into a state where it has arrived inside the cylindrical portion. Therefore, when the terminal is operated to generate sound from the speaker, the sound is expanded in the cylindrical portion due to effects such as sound directivity enhancement and resonance.

  Furthermore, in the assembly type voice expansion device of the present invention, the insertion port forming region is formed in the intermediate portion in the axial direction of the cylindrical portion. Therefore, the sound generated in the speaker can be distributed and propagated toward both sides of the terminal. Therefore, according to the assembling type audio expansion device of the present invention, the audio generated by the terminal speaker can be reproduced like a stereo system.

  In the assembly-type voice expansion device of the present invention described above, it is preferable that the terminal inserted into the terminal insertion port is in line contact with the inner peripheral surface of the cylindrical portion.

  In such a configuration, even when a terminal having a structure in which a speaker is provided near or in the vicinity of the bottom surface of the terminal body in a state of being inserted into the terminal insertion port, the speaker is included in the cylindrical portion. It can suppress that it is obstruct | occluded completely with a surrounding surface. This makes it possible to generate sound clearly from the speaker of the terminal.

  The assembly-type voice expansion device of the present invention described above is used by installing the cylindrical portion on the installation surface of the installation object, and the attitude of the terminal inserted into the terminal insertion port is: It is preferable that it has a terminal guide part which guides so that it may incline with respect to the normal line of the said installation surface.

  In the assembly-type voice expansion device of the present invention, the terminal inserted into the terminal insertion port is guided by the terminal guide unit and assumes an inclined posture. Therefore, by inserting the terminal into the terminal insertion port, the terminal is in line contact with the inner peripheral surface of the cylindrical portion. Thereby, even if the terminal to be used has a structure in which a speaker is provided on the bottom surface of the terminal body or in the vicinity thereof, the speaker can be prevented from being blocked by the inner peripheral surface of the cylindrical portion. Therefore, according to the present invention, it is possible to provide an assembly-type voice expansion device that can expand voice generated from a terminal speaker in a clear state.

  Moreover, the assembly-type audio expansion device of the present invention described above is provided with an insertion port forming region for forming the terminal insertion port on the sheet-like member, and an edge of the terminal insertion port is formed. Among them, a cut is formed in a portion corresponding to the other edge excluding one edge A extending in the axial direction of the cylindrical portion, and the insertion port forming region is formed in the cylinder so that the edge A forms a ridge line. It is possible to form the terminal guide part by pushing the inside of the shaped part or by pulling out the insertion port forming region to the outside of the tubular part.

  In the assembly type voice expansion device of the present invention, the terminal insertion port is formed by cutting and raising the sheet-like member inside or outside the cylindrical portion, and the cut-and-raised piece formed by cutting and raising is used as the terminal guide portion. Can be used.

  In such a configuration, when the assembly type voice expansion device is installed on the installation object, not only the tubular portion but also the installation surface reaching portion is in contact with the installation surface. Therefore, the assembly type voice expansion device of the present invention has high stability in the installed state.

  Further, in the assembly-type voice expansion device of the present invention described above, the sheet-like member is formed of a material having elasticity, and the sheet-like member is in the partial region in the axial direction of the cylindrical portion. It is possible to fix the sheet-like member in a non-fixed state in another region by being fixed by a fixing means.

  In such a configuration, when the tubular portion is formed by bending the sheet-like member, a force for returning to the original state by an elastic force acts on the sheet-like member. The fixing force acts against the elastic force of the sheet-like member at the portion fixed by the fixing means, but the non-fixed portion is bent in the direction away from the tubular portion by the elastic force. become. In the assembling type voice expansion device of the present invention, the fixing means is provided in a part of the cylindrical part in the axial direction, but the other part is not fixed. Therefore, on one end side of the sheet-like member, a part (unfixed part) of the installation surface reaching part formed in the region beyond the fixing position by the fixing means protrudes in a direction away from the cylindrical part. In the assembly type voice expansion device of the present invention, the protruding portion functions as a leg for supporting the cylindrical portion, and the stability in the installed state can be further improved.

  In the assembly-type speech expansion device of the present invention described above, it is preferable that a part of the installation surface reaching portion bend more greatly than other regions and be separated from the tubular part.

  In the assembly type speech expansion apparatus according to the present invention, a part of the installation surface reaching part is bent more greatly than the other part and is separated from the tubular part, so that the protruding part supports the tubular part. Act as a leg for. Therefore, according to the present invention, it is possible to provide an assembly-type voice expansion device that is excellent in stability in the installed state.

  Hereinafter, an assembly-type speech expansion apparatus 10 (hereinafter, also simply referred to as “speech expansion apparatus 10”) according to an embodiment of the present invention will be described in detail with reference to the drawings. The voice expansion device 10 has an external shape as shown in FIG. 1 in the assembled state. The voice expansion device 10 is an assembly-type device that can be used by being assembled using a rectangular sheet-like member 20 as shown in FIG. The sound expansion device 10 is for expanding sound output from a speaker 102 of a portable terminal 100 such as a smartphone, a mobile phone, a digital music player, or a tablet terminal. The voice expansion device 10 is used in a state of being installed on the installation surface 112 of the installation target object 110 such as a desk or a stand in the assembled state.

  The sheet-like member 20 is a sheet-like member made of a resin material such as polypropylene or PET resin, or paper. In the present embodiment, polypropylene is adopted as the material of the sheet-like member 20. As shown in FIG. 2, the sheet-like member 20 has a cylindrical part forming region 22 in which a cylindrical part 30 that forms the main part of the voice expansion device 10 is formed, and a fixing means forming region in which the fixing means 50 is formed. 24 and an installation surface reaching portion forming region 26 in which the installation surface reaching portion 60 is formed.

  Near both ends in the width direction of the sheet-like member 20, there are fixing means forming regions 24 (hereinafter, one side is also referred to as "fixing means forming region 24a" and the other side is also referred to as "fixing means forming region 24b"). Is provided. In addition, a region forming a large part of the sheet-like member 20 existing between the fixing means forming regions 24 a and 24 b in the sheet-like member 20 is a cylindrical portion forming region 22. Further, an area on the outer side in the width direction of the sheet-like member 20 with respect to one side of the fixing means forming areas 24a and 24b is an installation surface reaching part forming area 26. Specifically, the installation surface reaching portion forming area 26 is provided on the fixing means forming area 24a side where the engaging portion 52 described in detail later is provided in the fixing means forming areas 24a and 24b.

  In addition, in the tubular portion forming region 22, an insertion port forming region 28 for forming the terminal insertion port 32 and the terminal guide portion 40 is provided. As shown in FIG. 1 etc., the cylindrical part 30 and the installation surface reach | attainment part 60 can be formed by fixing with the fixing means 50 in the state which bent the cylindrical part formation area 22. FIG. Hereinafter, the structure of the voice expansion device 10 will be described in more detail.

  The tubular portion 30 is formed by bending the tubular portion forming region 22 of the sheet-like member 20 into a tubular shape. The cylindrical portion 30 may have a rectangular or polygonal cross-sectional shape, but in this embodiment, the cylindrical member 30 is formed so that the cross-sectional shape is circular or elliptical by rounding the sheet-like member 20. . Moreover, the cylindrical part 30 is made into the shape by which the internal space was made substantially hollow and the both ends were open | released. The shape of the cylindrical portion 30 is maintained by fixing the sheet-like member 20 by fixing means 50 described in detail later.

  As shown in FIG. 1 and FIG. 4, when the voice expansion device 10 is assembled, a terminal insertion port 32 is formed in the axial direction intermediate portion (substantially central portion in the present embodiment) of the tubular portion 30. The terminal insertion port 32 is a substantially rectangular opening formed by processing the insertion port forming region 28 provided in the sheet-like member 20. Specifically, in the sheet-like member 20, among the four edges A to D constituting the insertion port forming region 28, other edges B to D excluding the edge A extending in the axial direction of the cylindrical portion 30. The cut | interruptions 28b-28d are formed in the site | part applicable to these. When the voice expansion device 10 is assembled, the terminal insertion port 32 is formed by pushing the insertion port formation region 28 into the cylindrical portion 30 so that the ridge line 28a is formed at the portion corresponding to the edge A. Further, as shown in FIGS. 1 and 5, the portion corresponding to the insertion port forming region 28 is supported in a cantilevered manner with the edge A (ridge line 28a) as the base end, and will be described in detail later. It functions as the guide unit 40.

  As shown in FIG. 1 and FIG. 4, the opening width W1 of the terminal insertion port 32, that is, the length of the opening region in the longitudinal direction of the cylindrical portion 30 is the average of the terminal 100 such as a smartphone assumed to be used. Larger than the width W2. The opening width W1 is desirably about 1 cm to 5 cm larger than the width W2 of the terminal 100, and more preferably about 1.5 to 3 cm. When the opening width W <b> 1 is about this size, gaps 34 and 34 that are connected to the inside of the tubular portion 30 are formed on both sides of the terminal 100 in a state where the terminal 100 is inserted into the terminal insertion port 32. By providing the gaps 34, 34, not only the terminal 100 can be easily inserted into the terminal insertion port 32, but also improvement in sound quality and acoustic effect can be expected.

  As illustrated in FIG. 5, the terminal guide unit 40 is a guide for supporting the terminal 100 inserted into the terminal insertion port 32 so as not to fall down. When the terminal 100 is supported by the terminal guide unit 40, the terminal 100 is inclined with respect to the normal L of the installation surface 112. In other words, the terminal guide portion 40 extends from the edge A side (hereinafter also referred to as “back side”) of the insertion port forming region 28 to the edge C side (hereinafter also referred to as “front side”) opposite to the edge A. It is formed to have a downward slope as it goes. Therefore, when the terminal 100 is inserted into the terminal insertion port 32, the terminal 100 is inclined so as to have a downward slope from the back side to the front side of the voice expansion device 10. As a result, the part on the bottom surface 100 a side of the terminal 100 is in line contact with the inner peripheral surface 30 a of the cylindrical portion 30. Therefore, even if the terminal 100 to be used is capable of outputting sound generated by the speaker 102 from the bottom surface 100a side, the entire bottom surface 100a is blocked by being in surface contact with the inner peripheral surface 30a of the cylindrical portion 30. This can be suppressed.

  The fixing means 50 is for fixing the sheet-like member 20 so that the state which comprised the cylindrical part 30 mentioned above can be maintained. The fixing means 50 includes a plurality (two in this embodiment) of engaging structures 55 configured by a combination of the engaging portion 52 and the engaged portion 54. The engaging portion 52 and the engaged portion 54 constituting the fixing means 50 are both formed on the sheet-like member 20. That is, the fixing means 50 is integrally formed with the sheet-like member 20.

  As shown in FIG. 2, the engaging portion 52 is provided in the fixing means forming region 24 a provided on one end side in the width direction of the sheet-like member 20. The engaging portion 52 is a convex portion formed by cutting and raising the sheet-like member 20 along the cut 56 provided in the fixing means forming region 24a. The cuts 56 for constituting the engaging portion 52 are formed one by one near both ends in the longitudinal direction of the sheet-like member 20.

  The engaged portion 54 is constituted by a cut 58 provided in the fixing means forming region 24b. The cut 58 is formed so that the convex portion forming the engaging portion 52 can be removed. In addition, the cut line 58 is formed one by one near both ends in the longitudinal direction of the sheet-like member 20. Each cut 58 is formed at a position corresponding to each of the two convex portions forming the engaging portion 52.

  Here, as shown in FIG. 1, FIG. 5, etc., when assembling the voice expansion device 10, the fixing means forming region 24 b side where the engaged portion 54 is formed in the sheet-like member 20 is on the cylindrical portion 30. The tubular part 30 is formed by winding the sheet-like member 20 so that the fixing means forming region 24 a side where the engaging part 52 is formed is located outside the tubular part 30. That is, when the cylindrical portion 30 is formed, the fixing means forming area 24a overlaps the outside of the fixing means forming area 24b. Therefore, when the user assembles the voice expansion device 10, the tubular portion forming region 22 is bent (rounded) and held with one hand, and the other hand has a cut 56 in the fixing means forming region 24 a. The engaging member 52 is cut and raised along the fixing member forming region 24b and inserted into the engaged member 54 formed by the cut 58, so that the state in which the cylindrical member 30 is configured can be maintained. Can be fixed.

  As shown in FIG. 4, when the voice expansion device 10 is viewed in plan from the insertion port formation region 28 side, the fixing position by the fixing means 50 is the back side of the voice expansion device 10 (the edge A side of the insertion port formation region 28). Located in the area. As shown in FIG. 5, when the voice expansion device 10 is viewed from the side of both ends (opening ends) of the cylindrical portion 30, the fixing position by the fixing means 50 is equal to the height of the axial center position of the cylindrical portion 30. Or it is located in the area below it.

  The fixing means 50 fixes the sheet-like member 20 only in a partial region of the cylindrical portion 30 in the axial direction, and the sheet-like member 20 is not fixed in other regions. That is, when the voice expansion device 10 is assembled, the fixing means 50 is provided in the vicinity of both ends in the longitudinal direction of the sheet-like member 20 provided with the engaging portion 52 and the engaged portion 54 (in the vicinity of both ends in the axial direction of the tubular portion 30). The sheet-like member 20 is fixed only at, and the sheet-like member 20 is not fixed at other portions. Here, the sheet-like member 20 is formed of a flexible material, and exhibits an elastic force in a direction in which the sheet-like member returns to the original flat state when bent to form the cylindrical portion 30. . Therefore, as shown in FIG. 4, in the assembled state of the voice expansion device 10, the region that is not fixed by the fixing means 50 is bent in a direction away from the tubular portion 30 rather than the fixed region. Become.

  The installation surface reaching part 60 is a part constituted by the installation surface reaching part forming region 26 provided in the sheet-like member 20. As described above, the installation surface reaching portion forming region 26 is a region further provided on the outer side in the width direction with respect to the fixing means forming region 24 a provided on one end side in the width direction in the sheet-like member 20. Further, as described above, when the sheet-like member 20 is wound to assemble the voice expansion device 10, the end on the fixing means forming area 24 a side is outside the end on the fixing means forming area 24 b side. It is an overlapping part. Therefore, as shown in FIGS. 1 and 5, the installation surface reaching portion 60 protrudes beyond the fixing position of the sheet-like member 20 by the fixing means 50 on the back side of the voice expansion device 10. Further, the installation surface reaching section 60 is formed to reach the installation surface 112 by installing the voice expansion device 10 on the installation surface 112 so that the terminal insertion port 32 opens upward. . Therefore, when the voice expansion device 10 is installed on the installation surface 112, the installation surface 112 is brought into contact with not only the tubular portion 30 but also the installation surface reaching portion 60. In other words, the installation surface reaching portion 60 functions as a support leg that supports the cylindrical portion 30 so as not to fall.

  Here, as described above, the region that is not fixed by the fixing unit 50 in the fixing unit formation region 24a (in this embodiment, the intermediate region in the axial direction of the cylindrical portion 30) is more than the region that is fixed. It is in a state of bending in a direction away from the tubular portion 30. In addition, the installation surface reaching portion forming region 26 where the installation surface reaching portion 60 is provided is located at a position continuous to the fixing means forming region 24 a where the engaging portion 52 is provided. Therefore, as shown in FIG. 4, the installation surface reaching portion forming region 26 is also in a state of being bulged in a direction away from the tubular portion 30 in an intermediate region in the axial direction of the tubular portion 30. Thereby, the function of the installation surface reach | attainment part 60 as a support leg which supports so that the cylindrical part 30 may not fall is strengthened.

  As described above, the voice expansion device 10 according to the present embodiment can be used without using a power source or the like by being assembled using the sheet-like member 20. Therefore, the voice expansion device 10 can be carried in the state of the sheet-like member 20 and assembled and used at a place where it is desired to be used. Therefore, the voice expansion device 10 of this embodiment is excellent in portability and convenience. Further, since it is not necessary to use a power source, it is not necessary to prepare a separate power source or use the battery of the terminal 100. Therefore, the voice expansion device 10 can be suitably used in the outdoors where the power source cannot be used or in the terminal 100 where the battery capacity is not sufficient.

  Further, as shown in FIG. 5 and the like, the voice expansion device 10 inserts the terminal 100 into the terminal insertion port 32, so that the portion of the terminal 100 where the speaker 102 is provided fits inside the cylindrical portion 30. Thereby, the sound generated from the speaker 102 can be expanded by effects such as directivity enhancement and resonance in the cylindrical portion 30.

  Further, as shown in FIG. 5, in the voice expansion device 10, the terminal 100 inserted into the terminal insertion port 32 has an inclined posture guided by the terminal guide portion 40, and the inner peripheral surface of the tubular portion 30. Line contact is made to 30a. Therefore, even when the terminal 100 having a structure in which the speaker 102 is provided in the vicinity of the bottom surface 100a is used, the speaker 102 is prevented from being completely blocked by the inner peripheral surface 30a of the cylindrical portion 30, and the sound quality is reduced. It is possible to generate high voice.

  Moreover, the terminal guide part 40 is formed using a part of sheet-like member 20, and it is not necessary to prepare what becomes the terminal guide part 40 separately. Therefore, the voice expansion device 10 has a very simple configuration.

  In the present embodiment, an example in which the terminal guide portion 40 is formed by folding the insertion port forming region 28 provided in the sheet-like member 20 inside the cylindrical body 30 is shown, but the present invention is limited to this. Instead, the insertion port forming region 28 may be raised outside the cylindrical body 30 to form the terminal guide portion 40. In addition, the voice expansion device 10 may be configured by creating a member corresponding to the terminal guide unit 40 using a separate member or not providing the terminal guide unit 40. In addition, when it is assumed that the terminal 100 having a structure in which the speaker 102 is provided in the vicinity of the bottom surface 100a is used, the terminal 100 is inclined in the same manner as described above even when the terminal guide unit 40 is not provided. It is preferable to take measures to ensure posture.

  In the present embodiment, the insertion port forming region 28 is provided in the intermediate portion in the axial direction of the cylindrical portion 30. Therefore, the sound generated in the speaker 102 of the terminal 100 can be distributed and propagated to the left and right. Therefore, according to the audio expansion device 10, it is possible to reproduce the audio generated in the terminal 100 like a stereo system.

  As described above, the voice expansion device 10 is provided with the installation surface reaching unit 60. Therefore, when the voice expansion device 10 is installed on the installation object 110, not only the cylindrical portion 30 but also the installation surface reaching portion 60 is in contact with the installation surface 112, and the stability is high. Further, in the present embodiment, the sheet-like member 20 is fixed by the fixing means 50 in the regions on both ends in the axial direction of the cylindrical portion 30, and the sheet-like member 20 is not fixed in the intermediate portion in the axial direction. Yes. By adopting such a configuration, in the installation surface reaching portion 60, the intermediate portion in the axial direction of the tubular portion 30 is bent and bulged in a direction away from the tubular portion 30 rather than both end portions, and the tubular portion It can support so that 30 may not fall.

  In the present embodiment, the fixing position by the fixing means 50 is provided at both axial ends of the cylindrical portion 30, and the fixing means 50 is not fixed at the axial intermediate portion. It is not limited to this. Specifically, the fixing position by the fixing means 50 may be provided in the intermediate portion in the axial direction of the cylindrical portion 30, and the fixing means 50 may not be fixed at both ends in the axial direction. In the case of such a configuration, contrary to the example of the embodiment described above, both end portions in the axial direction of the cylindrical portion 30 are bent and bulged in a direction away from the cylindrical portion 30 rather than the intermediate portion. It becomes possible to function as support legs for supporting the bulging portions at both ends so that the cylindrical portion 30 does not fall down. Further, although not preferable from the viewpoint of improving the stability of the cylindrical portion 30, the sheet-like member 20 may be fixed by a member corresponding to the fixing means 50 in substantially the entire axial direction of the cylindrical portion 30. From the viewpoint of improving the stability of the cylindrical portion 30, when fixing the sheet-like member 20 in substantially the entire axial direction of the cylindrical portion 30, the cylindrical portion 30 itself is not easily toppled. Except in some cases, it is desirable to add a configuration for supporting the cylindrical portion 30.

  Further, in the voice expansion device 10 described above, the fixing means 50 is formed integrally with the sheet-like member 20. Therefore, the voice expansion device 10 has a simple configuration. The fixing means 50 can be integrally formed with the sheet-like member 20 as described above, but the present invention is not limited to this, and a separate member is used instead of the fixing means 50. It may be adopted. In addition to the fixing means 50, another fixing means may be provided.

  The voice expansion device 10 described above is configured such that a gap 34 communicating with the internal space of the tubular portion 30 is formed on the side of the terminal 100 in a state where the terminal 100 is inserted into the terminal insertion port 32. Thereby, the improvement of the sound quality and acoustic effect which generate | occur | produce in the terminal 100 inserted in the terminal insertion port 32 can be anticipated. Further, the terminal 100 can be easily inserted into the terminal insertion port 32.

  In the embodiment described above, an example in which only the sheet-like member 20 used for assembling the voice expansion device 10 is shown, but the present invention is not limited to this. Specifically, the sheet-like member 20 is provided as a part of the member constituting the other article, and the sheet-like member 20 can be appropriately separated from the other member constituting the other article when the voice expansion device 10 is used. It is also good. More specifically, for example, one or both of two sheets constituting a conventionally known clear folder are constituted by the sheet-like member 20, and the sheet-like member 20 is separated when used as the audio expansion device 10.
