In addition, the size and scale of each part in the accompanying drawings are appropriately different from the actual size and scale. In addition, the present embodiment described below is a preferred specific example of the present invention. Therefore, in this embodiment, various technically preferred limitations are attached. However, the scope of the present invention is not limited to these modes as long as there is no record of the content that specifically limits the present invention in the following description.

[0019] 1-1. Vehicle door 100

[0020] Figure 1 It is an exploded perspective view schematically showing the vehicle door 100 according to the first embodiment. Figure 2 Yes means Figure 1 1 is a schematic longitudinal cross-sectional view of a vehicle door 100 shown in FIG. 1. In addition, for the convenience of description, the following description is appropriately performed using mutually orthogonal X-axis, Y-axis and Z-axis. In addition, one direction along the X-axis is set as the X1 direction, and the direction opposite to the X1 direction is set as the X2 direction. Similarly, one direction along the Y-axis is set as the Y1 direction, and the direction opposite to the Y1 direction is set as the Y2 direction. One direction along the Z-axis is set as the Z1 direction, and the direction opposite to the Z1 direction is set as the Z2 direction.

[0021] like Figure 1 and Figure 2 As shown, the vehicle door 100 includes an outer panel 11, a door trim 12, an inner panel 13, an audio device 5, and a pad 6. The vehicle door 100 is used in a vehicle such as an automobile.

[0022] The outer panel 11 is an outer panel located on the outer side of the vehicle. The door trim 12 is an interior material located on the side of the vehicle interior. The inner panel 13 is arranged between the outer panel 11 and the door trim 12. A frame 16 that accommodates the window glass 15 in a manner that can move up and down is installed on the outer panel 11 and the inner panel 13. In addition, the audio device 5 is installed on the inner panel 13. The gasket 6 is located between the audio device 5 and the door trim 12, and connects the audio device 5 and the door trim 12.

[0023] The outer panel 11 and the inner panel 13 are respectively formed of metal plate members such as steel plates. The outer panel 11 and the inner panel 13 may be made of, for example, aluminum alloy, resin or carbon material. The door trim 12 may be made of, for example, resin.

[0024] The outer panel 11 and the inner panel 13 are connected to each other by welding, for example. Figure 2 As shown in FIG. 1 , a space S1 is formed between the outer panel 11 and the inner panel 13. Although not shown in the figure, a lifting mechanism and a door locking mechanism for lifting the window glass 15 in the vertical direction are arranged in the space S1. Figure 2 As shown, a sound absorbing member 19 is arranged in space S1 to absorb the sound generated by the audio device 5 and suppress standing waves. The sound absorbing member 19 is attached to the outer panel 11. The sound absorbing member 19 is arranged corresponding to the audio device 5. Specifically, the sound absorbing member 19 is located on the central axis A1 along the Z axis of the audio device 5.

[0025] like Figure 1As shown in FIG. 1 , the door trim 12 and the inner panel 13 are connected to each other by a plurality of connecting members 14. Each connecting member 14 is, for example, a rivet made of resin. One end of each connecting member 14 is fixed to the door trim 12, and the other end is inserted into a through hole 13c of the inner panel 13. Figure 2 As shown, a space is formed between the door trim 12 and the inner panel 13. The space is divided into a space S21 and a space S22 by the gasket 6. In addition, a gasket 17 is arranged between the door trim 12 and the inner panel 13. The gasket 17 is an annular rubber member arranged along the outer periphery of the door trim 12.

[0026] like Figure 1 and Figure 2 As shown, the door trim 12 has a plurality of through holes 12a. The plurality of through holes 12a are holes for emitting the sound generated by the audio device 5 into the vehicle interior. Figure 2 The Z2 direction of the vehicle door 100 in FIG. 1 corresponds to the direction toward the interior of the vehicle. Figure 2 The Z1 direction of the vehicle door 100 in the figure corresponds to the direction toward the outside of the vehicle compartment. In addition, the inner panel 13 has an opening 13a and a plurality of through holes 13b. The opening 13a is used to mount the audio device 5 on the inner panel 13. The opening 13a is a hole that penetrates the inner panel 13. In addition, the plurality of through holes 13b are used, for example, in the operation of arranging the aforementioned lifting mechanism and door locking mechanism in the space S1. In addition, the plurality of through holes 13b may be blocked by a component not shown in the figure, or may not be blocked.

[0027] 1-2. Sound device 5

[0028] Figure 3 Yes Figure 2 The illustrated diagram is an enlarged view of the audio device 5 included in the vehicle door 100 . Figure 4 Observed from the Z1 direction Figure 3 FIG. 5 shows an audio device 5. Figure 3 The illustrated audio device 5 is disposed corresponding to the opening 13a. The audio device 5 emits sound toward the vehicle interior.

[0029] like Figure 3 and Figure 4 As shown in FIG. 5 , the audio device 5 includes a speaker unit 50, a mounting member 55, a spring member 56, and a sealing member 57. Figure 3 In FIG. 5 , the spring member 56 and the sealing member 57 are schematically shown.

[0030] The speaker unit 50 is located in the opening 13 a . The speaker unit 50 is not in contact with both the door trim 12 and the inner panel 13 . Thus, the speaker unit 50 is separated from the door trim 12 and the inner panel 13 .

[0031] The speaker unit 50 includes a vibration plate 51, a frame 52, a driving unit 53, and a bracket 54. The vibration plate 51 includes a sound emitting surface 51a for emitting sound toward the vehicle interior. The speaker unit 50 is arranged so that the sound emitting surface 51a faces the door trim 12. The sound emitting surface 51a is exposed to the space S21. In addition, the vibration plate 51 is arranged inside a space surrounded by a cone-shaped frame 52. The outer edge of the vibration plate 51 is connected to the frame 52. Therefore, the frame 52 supports the vibration plate 51 so that it can vibrate. The material of the frame 52 is, for example, metal or resin. The bracket 54 is connected to the outer edge of the frame 52. The material of the bracket 54 is, for example, metal or resin.

[0032] A driving unit 53 is provided on the opposite side (Z1 direction) of the sound emitting surface 51a of the frame 52. The driving unit 53 includes, for example: a magnetic circuit including a magnet and a yoke; and a voice coil connected to the vibration plate 51. The driving unit 53, for example, guides the magnetic flux generated by the permanent magnet to the voice coil through the yoke, and vibrates the vibration plate 51 by the current flowing through the voice coil. The driving unit 53 vibrates the vibration plate 51 in response to the sound signal output from the circuit substrate not shown. In addition, the structure of the driving unit 53 may be any structure as long as it can vibrate the vibration plate 51. In addition, the speaker unit 50 may be a so-called cone type or other types. The speaker unit 50 may be a dome type, for example.

[0033] The mounting member 55 is connected to the portion of the inner panel 13 that forms the opening 13a. In the example shown in the figure, the mounting member 55 is in contact with the surface of the inner panel 13 that faces the door trim 12. The material of the mounting member 55 is, for example, metal or resin. The mounting member 55 is an annular member. The mounting member 55 extends from the edge 130a of the opening 13a toward the center over the entire circumference of the edge 130a of the opening 13a. In other words, the mounting member 55 is separated from the speaker unit 50 and extends from the speaker unit 50 toward the inner panel 13. The mounting member 55 has an opening 55a corresponding to the speaker unit 50. Specifically, the sound emitting surface 51a of the speaker unit 50 is exposed from the opening 55a. When viewed from the Z1 direction, the opening 55a is located on the inner side of the opening 13a, and the speaker unit 50 is located on the inner side of the opening 55a. The opening 55a is a hole that passes through the mounting member 55. The speaker unit 50 is arranged in the opening 55a of the mounting member 55. The speaker unit 50 is not in contact with the mounting member 55. Thus, the speaker unit 50 and the mounting member 55 are separated.

[0034] The mounting member 55 has a structure for mounting the speaker unit 50 on the door trim 12 and the inner panel 13. Specifically, the mounting member 55 has a plurality of first mounting holes 551 and a plurality of second mounting holes 552. The first mounting holes 551 are structures for mounting the audio device 5 on the door trim 12 via the gasket 6. The second mounting holes 552 are structures for mounting the audio device 5 on the inner panel 13. Here, the door trim 12 is an example of one of the two objects. The inner panel 13 is an example of the other of the two objects.

[0035] The mounting member 55 is connected to the inner panel 13 via a plurality of second fixing members 22. The second fixing members 22 are, for example, screws. The second fixing members 22 are inserted through the second mounting holes 552 and inserted into the holes of the inner panel 13. For example, internal threads are formed in the holes of the inner panel 13 and the second mounting holes 552.

[0036] The mounting member 55 is connected to the gasket 6 through a plurality of first fixing members 21. The first fixing member 21 is an example of a fixing member. The gasket 6 is connected to the door trim 12. The first fixing member 21 is, for example, a rivet made of resin. A rivet is also called a fastener. The first fixing member 21 is inserted into the first mounting hole 551 in an elastically deformed state, for example.

[0037] A spring member 56 and a sealing member 57 are arranged between the mounting member 55 and the speaker unit 50. In the illustrated example, the sealing member 57 is located between the spring member 56 and the door trim 12. Alternatively, the spring member 56 may be located between the sealing member 57 and the door trim 12. The sealing member 57 and the spring member 56 are separated from each other. However, a portion of the sealing member 57 may be in contact with the spring member 56.

[0038] The spring member 56 connects the mounting member 55 and the speaker unit 50. The spring member 56 is an annular member. The speaker unit 50 is arranged in the opening of the spring member 56. In addition, the spring member 56 is fixed to the mounting member 55 and the speaker unit 50 respectively by, for example, screws. The spring member 56 has elasticity. The spring member 56 is, for example, a leaf spring. The material of the spring member 56 is, for example, metal or resin.

[0039] Specifically, in Figure 4 In the example shown, the spring member 56 has an inner wheel 561, an outer wheel 562, and a plurality of leaf spring portions 563. The inner wheel 561 is connected to the speaker unit 50. The outer wheel 562 is connected to the mounting member 55. The plurality of leaf spring portions 563 are located between the inner wheel 561 and the outer wheel 562 when viewed from the Z1 direction. The plurality of leaf spring portions 563 are separated from each other. Each leaf spring portion 563 has elasticity and connects the inner wheel 561 and the outer wheel 562. Figure 4In the example shown, the number of the leaf spring portions 563 is four, but the number may be one, two, three, or five or more.

[0040] In addition, the spring member 56 is not limited to a leaf spring, and may be other spring members. For example, the spring member 56 may be a coil spring. In addition, when the spring member 56 is a leaf spring, the shape of the spring member 56 is not limited to Figure 4 The example shown may also be in other shapes. In addition, the number of the spring member 56 is not limited to one, and may be plural.

[0041] The sealing member 57 seals between the mounting member 55 and the speaker unit 50. The sealing member 57 is an annular member. The speaker unit 50 is arranged in the opening of the sealing member 57. In addition, the sealing member 57 is fixed to the mounting member 55 and the speaker unit 50, respectively, for example, by screws or adhesives. The sealing member 57 has elasticity. The sealing member 57 is, for example, a rubber film. In addition, the material of the sealing member 57 is not limited to rubber, and may be resin or the like. In addition, the sealing member 57 is not limited to a film shape, and may be, for example, a block shape.

[0042] 1-3. Gasket 6

[0043] like Figure 3 As shown, the pad 6 is disposed between the mounting member 55 and the door trim 12, and is connected to the mounting member 55 and the door trim 12. As described above, the pad 6 is connected to the mounting member 55 via the first fixing member 21. In addition, the pad 6 may be formed separately from the door trim 12 and connected thereto, or may be formed integrally therewith.

[0044] The gasket 6 is an annular sealing member. The gasket 6 has rigidity. The gasket 6 seals between the mounting member 55 and the door trim 12. The gasket 6 does not overlap with the speaker unit 50 when viewed from the Z1 direction, and surrounds the speaker unit 50.

[0045] The vehicle door 100 described above includes the door trim 12, the inner panel 13 having the opening 13a, and the audio device 5 mounted on the opening 13a. The audio device 5 includes the mounting member 55, the speaker unit 50, the spring member 56, and the sealing member 57.

[0046] Moreover, the spring member 56 connects the mounting member 55 and the speaker unit 50. That is, the speaker unit 50 is connected to the mounting member 55 via the spring member 56. Therefore, the speaker unit 50 is not directly mounted on the mounting member 55. The speaker unit 50 is connected to the mounting member 55 via the spring member 56, so the spring member 56 is elastically deformed due to the vibration generated by the speaker unit 50. Therefore, the vibration generated by the speaker unit 50 is weakened in the mounting member 55. Thus, the degree of vibration generated in the mounting member 55 due to the vibration of the speaker unit 50 is weakened. Therefore, the degree of vibration generated in the inner panel 13 directly connected to the mounting member 55 is weakened. As a result, the noise generated due to the vibration of the inner panel 13 can be suppressed.

[0047] Furthermore, the pad 6 connects the audio device 5 and the door trim 12. Therefore, the pad 6 is directly connected to the mounting member 55. Furthermore, the pad 6 is directly connected to the door trim 12. Therefore, the door trim 12 and the speaker unit 50 are connected via the spring member 56, the mounting member 55, and the pad 6. For the connection between the door trim 12 and the speaker unit 50, the spring member 56 is used, thereby suppressing the vibration of the door trim 12 due to the vibration of the speaker unit 50. As a result, the noise generated by the vibration of the door trim 12 is suppressed. According to the above, the presence of the spring member 56 suppresses the noise compared to the case where the spring member 56 does not exist. Therefore, the sound quality of the sound generated from the audio device 5 is improved.

[0048] In addition, the sealing member 57 seals between the mounting member 55 and the speaker unit 50. The presence of the sealing member 57 can prevent the sound emitted from the opposite side of the speaker unit 50 from the sound emitting surface 51a from being emitted through the mounting member 55 and the speaker unit 50. That is, the presence of the sealing member 57 can prevent the sound emitted in the Z1 direction of the speaker unit 50 from being circulated in the Z2 direction of the speaker unit 50.

[0049] As described above, sealing member 57 has elasticity. Therefore, sealing member 57 is elastically deformed by the vibration generated by speaker unit 50. Thus, the vibration generated by speaker unit 50 is prevented from being transmitted to mounting member 55 via sealing member 57.

[0050] In the present embodiment, the rigidity of mounting member 55 is greater than the rigidity of sealing member 57. Therefore, mounting member 55 can stably maintain the state in which speaker unit 50 is located in opening 13a.

[0051] In addition, as described above, the gasket 6 seals between the mounting member 55 and the door trim 12. The presence of the gasket 6 prevents the sound emitted from the speaker unit 50 from being emitted from the space S21 into the space S22. Thus, the sound emitted from the speaker unit 50 is prevented from leaking into the space S22. As a result, the sound emitted from the speaker unit 50 is efficiently emitted into the vehicle interior via the plurality of through holes 12a.

[0052] In addition, the rigidity of the gasket 6 is greater than the rigidity of the sealing member 57. Therefore, the door trim 12 is more firmly fixed to the mounting member 55 by the gasket 6, compared with the case where the rigidity of the gasket 6 is less than the rigidity of the sealing member 57. Therefore, unnecessary vibration of the door trim 12 is suppressed. Therefore, noise is further suppressed. In addition, the rigidity of the gasket 6 may be equal to the rigidity of the sealing member 57, or may be less than the rigidity thereof.

[0053] As described above, the gasket 6 is fixed to the mounting member 55 using the first fixing member 21. Specifically, the gasket 6 is directly connected to the mounting member 55 using the first fixing member 21. That is, the gasket 6 and the mounting member 55 are in contact with each other. Therefore, compared with the case where the gasket 6 is connected to the mounting member 55 via a cushioning material such as sponge, the airtightness between the mounting member 55 and the door trim 12 can be improved by the gasket 6. As a result, sound leakage is more effectively suppressed.

[0054] In addition, the speaker unit 50, the spring member 56, and the mounting member 55 are arranged in the direction perpendicular to the central axis A1 of the opening 13a, that is, in the direction of the X-axis. Therefore, compared with the case where the speaker unit 50, the spring member 56, and the mounting member 55 are not arranged in the direction along the X-axis, the vehicle door 100 can be made thinner. In addition, as long as the speaker unit 50, the spring member 56, and the mounting member 55 do not overlap when viewed from the direction along the Z-axis, they may be arranged in a direction other than the direction along the X-axis.

[0055] 1-4. Specific examples

[0056] Figure 5 1 is a cross-sectional view showing an acoustic device 5x according to a specific embodiment of the first embodiment. Figure 5 , a specific embodiment of the spring member 56x and the sealing member 57x included in the acoustic device 5x is shown. Figure 5 The spring member 56 x shown is arranged to correspond to the spring member 56 described above. Figure 5 The sealing member 57x shown is configured to correspond to the aforementioned sealing member 57. Figure 5 The mounting member 55x shown is configured to correspond to the aforementioned mounting member 55. Figure 5 is with Figure 4One embodiment of the acoustic device 5 corresponds to the cross section along line AA of FIG.

[0057] like Figure 5 As shown, mounting member 55x is arranged outside speaker unit 50. Bracket 54 included in speaker unit 50 is fixed to frame 52 by screws 24.

[0058] A sealing member 57x and a spring member 56x are arranged in a region between the speaker unit 50 and the mounting member 55x. The speaker unit 50 is mounted on the mounting member 55x via the sealing member 57x. Therefore, the speaker unit 50 is not directly mounted on the mounting member 55x.

[0059] Spring member 56x is fixed to speaker unit 50 by screw 23. Spring member 56x is fixed to mounting member 55x by screw 25. Thus, speaker unit 50x is mounted to mounting member 55x via spring member 56x. Therefore, speaker unit 50x is not directly mounted to mounting member 55x.

[0060] Moreover, the mounting member 55x is connected to the inner panel 13 via the second fixing member 22. Moreover, the mounting member 55x is connected to the pad 6 via the first fixing member 21. Thus, the mounting member 55x is mounted to the door trim 12 via the pad 6.

[0061] in addition, Figure 5 The acoustic device 5x shown has a first buffer member 501 and a second buffer member 502. The first buffer member 501 is located between the mounting member 55x, the bracket 54, and the inner panel 13. The first buffer member 501 is in contact with the bracket 54, the mounting member 55x, and the inner panel 13. The presence of the first buffer member 501 suppresses the vibration of the inner panel 13 compared to the case where the first buffer member 501 is not present. As a result, noise is further suppressed.

[0062] The second buffer member 502 is located between the mounting member 55x and the gasket 6 and is in contact with the mounting member 55x and the gasket 6. Therefore, the second buffer member 502 can suppress the door trim 12 from vibrating via the gasket 6 compared to a case where the second buffer member 502 is not present. This further suppresses noise.

[0063] 2. Second Implementation Method

[0064] In the following examples, the elements having the same functions as those in the first embodiment are denoted by the same reference numerals as those used in the description of the first embodiment, and detailed descriptions thereof are omitted as appropriate.

[0065] Figure 61 is a schematic longitudinal sectional view showing an acoustic device 5A according to the second embodiment. The second embodiment is the same as the first embodiment except that the acoustic device 5A includes a sealing member 59 instead of the spring member 56 and the sealing member 57 of the first embodiment.

[0066] like Figure 6 As shown, the audio device 5A of this embodiment includes a mounting member 55, a speaker unit 50, and a sealing member 59. The sealing member 59 included in the audio device 5A is located between the speaker unit 50 and the mounting member 55, and connects the speaker unit 50 and the mounting member 55. In addition, the sealing member 59 seals between the mounting member 55 and the speaker unit 50. The sealing member 59 is fixed to the mounting member 55 and the speaker unit 50 by, for example, an adhesive or a screw. The sealing member 59 has elasticity. The material of the sealing member 59 is, for example, rubber and resin. The sealing member 59 is an annular member. A part of the speaker unit 50 is arranged in the opening included in the sealing member 59.

[0067] The sealing member 59 has the functions of both the spring member 56 and the sealing member 57 of the first embodiment. Therefore, the sealing member 59 has an elastic body like the spring member 56. The sealing member 59 stably maintains the state where the speaker unit 50 is located in the opening 13a.

[0068] In the present embodiment, as described above, the speaker unit 50 and the mounting member 55 are connected via the sealing member 59. Therefore, the sealing member 59 is elastically deformed due to the vibration generated by the speaker unit 50. Therefore, the vibration generated by the speaker unit 50 is weakened in the mounting member 55. Thus, the degree of vibration of the mounting member 55 due to the vibration of the speaker unit 50 is weakened. Therefore, the degree of vibration of the inner panel 13 directly mounted on the mounting member 55 is weakened. As a result, the noise generated by the vibration of the inner panel 13 can be suppressed.

[0069] In addition, the door trim 12 and the speaker unit 50 are connected via the sealing member 59 and the gasket 6. The sealing member 59 is used for the connection between the door trim 12 and the speaker unit 50, so that the vibration of the door trim 12 due to the vibration of the speaker unit 50 is suppressed. As a result, the occurrence of flutter sound due to the vibration of the door trim 12 is suppressed. As described above, the presence of the sealing member 59 suppresses noise compared to the case where the sealing member 59 is not present.

[0070] In addition, the sealing member 59 seals between the mounting member 55 and the speaker unit 50. Therefore, it is possible to prevent the sound emitted from the opposite side of the speaker unit 50 from the sound emitting surface 51a from being emitted through the mounting member 55 and the speaker unit 50. That is, the presence of the sealing member 59 can prevent the sound emitted in the Z1 direction of the speaker unit 50 from being circulated in the Z2 direction of the speaker unit 50.

[0071] In addition, the rigidity of the gasket 6 is greater than the rigidity of the sealing member 59. Therefore, compared with the case where the rigidity of the gasket 6 is less than the rigidity of the sealing member 59, the door trim 12 can be more firmly fixed to the mounting member 55 by the gasket 6. Therefore, unnecessary vibration of the door trim 12 is suppressed. Therefore, noise is further suppressed. In addition, the rigidity of the gasket 6 may be equal to the rigidity of the sealing member 59, or may be less than the rigidity thereof.

[0072] According to the second embodiment described above, noise can be suppressed as in the first embodiment, and thus the sound quality of the sound generated from the acoustic device 5A can be improved.

[0073] 2. Modifications

[0074] The above-mentioned embodiments can be modified in many ways. Two or more embodiments arbitrarily selected from the following examples can be appropriately combined within the scope of non-contradiction.

[0075] In each embodiment, the speaker unit 50 is mounted on the door trim 12 and the inner panel 13. However, the speaker unit 50 may be mounted on two other objects other than the door trim 12 and the inner panel 13. The mounting member 55 has the first mounting hole 551 and the second mounting hole 552, so the speaker unit 50 can be mounted on two other objects other than the door trim 12 and the inner panel 13. For example, as the two objects, two members forming the ceiling portion of the vehicle can be cited.

[0076] In each embodiment, the speaker unit 50 is located in the opening 13a. However, the speaker unit 50 may not be located in the opening 13a. For example, the speaker unit 50 may be located in the Z1 direction relative to the opening 13a.

[0077] In various embodiments, Figure 3 and Figure 5 As shown, the speaker unit 50 and the mounting member 55 are not in contact with each other. However, the speaker unit 50 and the mounting member 55 may have a portion in contact with each other as long as they are not directly mounted on each other. However, by making the speaker unit 50 and the mounting member 55 not in contact with each other, noise is further suppressed.

[0078] 3. At least one method that can be understood from the embodiment and each modification example

[0079] The following aspects can be understood from at least one of the above-mentioned embodiment and each modification example.

[0080] One mode of a vehicle door comprises: a door trim; an inner panel having an opening; an audio device mounted on the edge of the opening of the inner panel; and a gasket connecting the audio device and the door trim.

According to this mode, the vibration of the door trim and the inner panel due to the transmission of the vibration of the speaker unit to the door trim and the inner panel is suppressed. Thus, noise is suppressed. As a result, the sound quality of the sound generated by the audio device is improved.

[0082] As one embodiment of the vehicle door, the rigidity of the gasket is preferably greater than the rigidity of the sealing member. According to this embodiment, the door trim is more firmly fixed to the mounting member by the gasket. As a result, unnecessary vibration of the door trim is suppressed. Therefore, noise is further suppressed.

[0083] As one embodiment of the vehicle door, the liner is preferably fixed to the mounting member using a fixing member. According to this embodiment, the liner can be directly connected to the mounting member using the fixing member, thereby more effectively suppressing sound leakage compared to a case where a buffer material is present between the liner and the mounting member.

[0084] As one embodiment of the vehicle door, the speaker unit, the spring member, and the mounting member are preferably arranged in a direction perpendicular to the central axis of the opening. According to this embodiment, the vehicle door can be made thinner than when the speaker unit, the spring member, and the mounting member are arranged in a direction perpendicular to the central axis.

[0085] One mode of an audio device includes: a speaker unit; a mounting component having an opening corresponding to the speaker unit and having a structure for mounting the speaker unit on two objects; a spring component connecting the mounting component and the speaker unit; and a sealing component that seals the gap between the mounting component and the speaker unit and has elasticity. According to this mode, the vibration of the speaker unit 50 is suppressed from being transmitted to two objects and vibrating the two objects. Thus, the noise generated by the vibration of the two objects is suppressed. As a result, the sound quality of the sound generated from the audio device is improved.

[0086] One mode of an audio device includes: a speaker unit; a mounting member having an opening corresponding to the speaker unit and having a structure for mounting the speaker unit on two objects; and a sealing member that seals a gap between the mounting member and the speaker unit. The sealing member includes an elastic body. According to this mode, vibration of the two objects due to the transmission of the vibration of the speaker unit 50 to the two objects is suppressed. Thus, noise generated by the vibration of the two objects is suppressed. As a result, the sound quality of the sound generated from the audio device is improved.

[0087] As one embodiment of the above-mentioned audio device, the mounting component has: a first mounting hole for mounting one of the two objects on the mounting component; and a second mounting hole for mounting the other of the two objects on the mounting component. According to this embodiment, the speaker unit can be mounted on two objects by the mounting component.
