Further, the plurality of through holes 13b are used, for example, in the work of arranging the above-mentioned lifting mechanism, door lock mechanism, etc. in the space S1. Note that the plurality of through holes 13b may or may not be blocked by parts not shown.

1-2. Sound device 5
FIG. 3 is an enlarged view of the acoustic device 5 included in the vehicle door 100 shown in FIG. 2. As shown in FIG. FIG. 4 is a diagram of the acoustic device 5 shown in FIG. 3 viewed in the Z1 direction. The acoustic device 5 shown in FIG. 3 is arranged corresponding to the opening 13a. The acoustic device 5 emits sound toward the interior of the vehicle.

As shown in FIGS. 3 and 4, the audio device 5 includes a speaker unit 50, a mounting member 55, a spring member 56, and a sealing member 57. Note that in FIG. 3, the spring member 56 and the sealing member 57 are schematically shown.

The speaker unit 50 is located within the opening 13a. The speaker unit 50 is not in contact with both the door trim 12 and the inner panel 13. Therefore, the speaker unit 50 is spaced apart from the door trim 12 and from the inner panel 13.

The speaker unit 50 includes a diaphragm 51, a frame 52, a drive section 53, and a bracket 54. The diaphragm 51 has a sound emitting surface 51a that emits 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. Further, the diaphragm 51 is arranged inside a space surrounded by a cone-shaped frame 52. The outer edge of the diaphragm 51 is connected to the frame 52. Therefore, the frame 52 supports the diaphragm 51 so that it can vibrate. The material of the frame 52 is, for example, metal or resin. A bracket 54 is connected to the outer edge of the frame 52. The material of the bracket 54 is, for example, metal or resin.

A driving section 53 is provided on the opposite side (Z1 direction) of the frame 52 from the sound emitting surface 51a. The drive unit 53 includes, for example, a magnetic circuit including a magnet and a yoke, and a voice coil connected to the diaphragm 51. The drive unit 53, for example, guides magnetic flux generated by a permanent magnet to the voice coil through a yoke, and vibrates the diaphragm 51 by a current flowing through the voice coil. The drive unit 53 vibrates the diaphragm 51 in response to an audio signal output from a circuit board (not shown). Note that the drive unit 53 may have any configuration as long as it can vibrate the diaphragm 51. Further, although the speaker unit 50 is of a so-called cone type, other types may be used. The speaker unit 50 may have a dome shape, for example.

The attachment member 55 is connected to a portion of the inner panel 13 that forms the opening 13a. In the illustrated example, the attachment member 55 contacts 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 attachment 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. From another perspective, the mounting member 55 is spaced apart 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 in the Z1 direction, the opening 55a is located inside the opening 13a, and the speaker unit 50 is located inside the opening 55a. The opening 55a is a hole passing through the mounting member 55. The speaker unit 50 is arranged within the opening 55a of the mounting member 55. The speaker unit 50 is not in contact with the mounting member 55. Therefore, the speaker unit 50 is spaced apart from the mounting member 55.

The attachment member 55 has a structure for attaching the speaker unit 50 to 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 attachment hole 551 is a structure for attaching the acoustic device 5 to the door trim 12 via the gasket 6. The second attachment hole 552 is a structure for attaching the acoustic device 5 to the inner panel 13. Here, the door trim 12 is an example of one of the two items. Inner panel 13 is an example of the other of the two.

The mounting member 55 is connected to the inner panel 13 by a plurality of second fixing members 22 . The second fixing member 22 is, for example, a screw. The second fixing member 22 is inserted into the second attachment hole 552 and into a hole that the inner panel 13 has. For example, a female thread is formed in the hole of the inner panel 13 and the second attachment hole 552.

The mounting member 55 is connected to the gasket 6 by a plurality of first fixing members 21 . The first fixing member 21 is an example of a fixing member. Gasket 6 is connected to door trim 12. The first fixing member 21 is, for example, a rivet made of resin. Rivets are also called fasteners. The first fixing member 21 is inserted into the first attachment hole 551 in an elastically deformed state, for example.

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. Note that 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 spaced apart from each other. However, a portion of the sealing member 57 may be in contact with the spring member 56.

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 that the spring member 56 has. Further, the spring member 56 is fixed to each of the mounting member 55 and the speaker unit 50 with, for example, screws. The spring member 56 has elasticity. The spring member 56 is, for example, a plate spring. The material of the spring member 56 is, for example, metal or resin.

Specifically, in the example shown in FIG. 4, the spring member 56 has an inner ring 561, an outer ring 562, and a plurality of leaf spring parts 563. Inner ring 561 is connected to speaker unit 50. Outer ring 562 is connected to mounting member 55. The plurality of leaf spring parts 563 are located between the inner ring 561 and the outer ring 562 when viewed in the Z1 direction. The plurality of leaf spring parts 563 are spaced apart from each other. Each leaf spring portion 563 has elasticity and connects the inner ring 561 and the outer ring 562. In the example shown in FIG. 4, the number of leaf spring parts 563 is four, but it may be one, two, three, five or more.

Note that the spring member 56 is not limited to a leaf spring, and may be other spring materials. For example, the spring member 56 may be a helical spring. Moreover, when the spring member 56 is a plate spring, the shape of the spring member 56 is not limited to the example shown in FIG. 4, and may be any other shape. Further, the number of spring members 56 is not limited to one, but may be plural.

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 that the sealing member 57 has. Further, the sealing member 57 is fixed to each of the mounting member 55 and the speaker unit 50 by, for example, screws or adhesive. The sealing member 57 has elasticity. The sealing member 57 is, for example, a rubber membrane. Note that the material of the sealing member 57 is not limited to rubber, and may be resin or the like. Further, the sealing member 57 is not limited to a film shape, and may be, for example, a block shape.

1-3. gasket 6
As shown in FIG. 3, the gasket 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 mentioned above, the gasket 6 is connected to the mounting member 55 by the first fixing member 21. Note that the gasket 6 may be formed separately from and connected to the door trim 12, or may be formed integrally with the door trim 12.

Gasket 6 is an annular sealing member. Gasket 6 has rigidity. Gasket 6 seals between mounting member 55 and door trim 12. The gasket 6 surrounds the speaker unit 50 without overlapping the speaker unit 50 when viewed in the Z1 direction.

As described above, the vehicle door 100 described above includes the door trim 12, the inner panel 13 having the opening 13a, and the acoustic device 5 attached to the opening 13a. The audio device 5 includes a mounting member 55, a speaker unit 50, a spring member 56, and a sealing member 57.

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 attached to the attachment member 55. Since the speaker unit 50 is connected to the mounting member 55 via the spring member 56, the spring member 56 is elastically deformed by vibrations generated by the speaker unit 50. Therefore, the vibrations generated by the speaker unit 50 are reduced by the mounting member 55. Therefore, vibration of the mounting member 55 due to vibration of the speaker unit 50 is reduced. Therefore, vibration of the inner panel 13 directly connected to the mounting member 55 is reduced. As a result, noise generated by vibration of the inner panel 13 can be suppressed.

Further, the gasket 6 connects the audio device 5 and the door trim 12. Therefore, the gasket 6 is directly connected to the mounting member 55. A door trim 12 is directly connected to the gasket 6. Therefore, the door trim 12 and the speaker unit 50 are connected via the spring member 56, the mounting member 55, and the gasket 6. Since the spring member 56 is used to connect the door trim 12 and the speaker unit 50, vibration of the door trim 12 due to vibration of the speaker unit 50 is suppressed. As a result, noise generated by vibration of the door trim 12 is suppressed. For this reason, the presence of the spring member 56 suppresses noise compared to the case where the spring member 56 does not exist. Therefore, the quality of the sound generated from the audio device 5 can be improved.

Further, the sealing member 57 seals between the mounting member 55 and the speaker unit 50. The presence of the sealing member 57 prevents the sound emitted from the side opposite to the sound emitting surface 51a of the speaker unit 50 from being emitted through the space between the mounting member 55 and the speaker unit 50. That is, the presence of the sealing member 57 prevents the sound emitted in the Z1 direction of the speaker unit 50 from going around to the Z2 direction of the speaker unit 50.

Furthermore, as described above, the sealing member 57 has elasticity. Therefore, the sealing member 57 is elastically deformed by the vibrations generated by the speaker unit 50. Therefore, vibrations generated by the speaker unit 50 are suppressed from being transmitted to the mounting member 55 via the sealing member 57.

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

Further, as described above, the gasket 6 seals between the mounting member 55 and the door trim 12. The presence of the gasket 6 suppresses the sound emitted from the speaker unit 50 from being emitted from the space S21 into the space S22. Therefore, leakage of sound emitted from the speaker unit 50 into the space S22 is suppressed. As a result, the sound emitted from the speaker unit 50 is efficiently emitted into the vehicle interior through the plurality of through holes 12a.

Further, the rigidity of the gasket 6 is greater than that of the sealing member 57. Therefore, the door trim 12 is more firmly fixed to the mounting member 55 by the gasket 6 than in the case where the rigidity of the gasket 6 is less than that of the sealing member 57. Therefore, generation of unnecessary vibrations of the door trim 12 is suppressed. Therefore, noise is further suppressed. Note that the rigidity of the gasket 6 may be equal to or less than the rigidity of the sealing member 57.

As mentioned 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 . In other words, the gasket 6 and the mounting member 55 are in contact with each other. Therefore, compared to the case where the gasket 6 is connected to the mounting member 55 via a cushioning material such as a sponge, the gasket 6 can improve the airtightness between the mounting member 55 and the door trim 12. Therefore, sound leakage is suppressed more effectively.

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

1-4. Specific Example FIG. 5 is a sectional view showing a specific example of the acoustic device 5x of the first embodiment. Hereinafter, with reference to FIG. 5, a specific embodiment of the spring member 56x and the sealing member 57x included in the acoustic device 5x will be shown. A spring member 56x shown in FIG. 5 corresponds to the spring member 56 described above. A sealing member 57x shown in FIG. 5 corresponds to the sealing member 57 described above. Further, the mounting member 55x shown in FIG. 5 corresponds to the above-mentioned mounting member 55. Further, FIG. 5 shows one embodiment of the acoustic device 5 corresponding to the cross section taken along the line AA in FIG.

As shown in FIG. 5, a mounting member 55x is arranged on the outside of the speaker unit 50. Note that the bracket 54 included in the speaker unit 50 is fixed to the frame 52 with screws 24.

A sealing member 57x and a spring member 56x are arranged in the area between the speaker unit 50 and the mounting member 55x. The speaker unit 50 is attached to the attachment member 55x via the sealing member 57x. Therefore, the speaker unit 50 is not directly attached to the attachment member 55x.

The spring member 56x is fixed to the speaker unit 50 with the screw 23. Further, the spring member 56x is fixed to the mounting member 55x with the screw 25. Therefore, the speaker unit 50x is attached to the mounting member 55x via the spring member 56x. Therefore, the speaker unit 50 is not directly attached to the attachment member 55x.

Further, the attachment member 55x is connected to the inner panel 13 by the second fixing member 22. Further, the mounting member 55x is connected to the gasket 6 by the first fixing member 21. Therefore, the attachment member 55x is attached to the door trim 12 via the gasket 6.

Further, the acoustic device 5x shown in FIG. 5 includes a first buffer member 501 and a second buffer member 502. The first buffer member 501 is located between the mounting member 55x and the bracket 54, and the inner panel 13. The first buffer member 501 contacts the bracket 54, the mounting member 55x, and the inner panel 13. The presence of the first buffer member 501 suppresses the occurrence of vibrations in the inner panel 13 compared to the case where the first buffer member 501 does not exist. Therefore, noise is further suppressed.

The second buffer member 502 is located between the mounting member 55x and the gasket 6, and contacts the mounting member 55x and the gasket 6. Therefore, the presence of the second buffer member 502 suppresses the vibration of the door trim 12 via the gasket 6 compared to the case where the second buffer member 502 does not exist. Therefore, noise is further suppressed.

2. Second Embodiment A second embodiment will be described. In each of the following examples, for elements whose functions are similar to those in the first embodiment, the reference numerals used in the description of the first embodiment will be used, and detailed description of each will be omitted as appropriate.

FIG. 6 is a vertical cross-sectional view schematically showing an audio 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 sealing member 57 of the first embodiment.

As shown in FIG. 6, 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. Further, 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 using, for example, adhesive or screws. The sealing member 59 has elasticity. The material of the sealing member 59 is, for example, rubber or resin. The sealing member 59 is an annular member. A portion of the speaker unit 50 is placed in the opening that the sealing member 59 has.

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 in which the speaker unit 50 is located within the opening 13a.

In this embodiment, the speaker unit 50 and the mounting member 55 are connected via the sealing member 59 as described above. Therefore, the sealing member 59 is elastically deformed by the vibrations generated by the speaker unit 50. Therefore, the vibrations generated by the speaker unit 50 are reduced by the mounting member 55. Therefore, vibration of the mounting member 55 due to vibration of the speaker unit 50 is reduced. Therefore, vibration of the inner panel 13 directly attached to the attachment member 55 is reduced. As a result, noise generated by vibration of the inner panel 13 can be suppressed.

Further, the door trim 12 and the speaker unit 50 are connected via a sealing member 59 and a gasket 6. Since the sealing member 59 is used to connect the door trim 12 and the speaker unit 50, vibration of the door trim 12 due to vibration of the speaker unit 50 is suppressed. As a result, generation of chattering noise due to vibration of the door trim 12 is suppressed. For this reason, the presence of the sealing member 59 suppresses noise compared to the case where the sealing member 59 does not exist.

Further, 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 side opposite to the sound emitting surface 51a of the speaker unit 50 from passing between the mounting member 55 and the speaker unit 50 and being emitted. That is, the presence of the sealing member 59 can prevent the sound emitted from the speaker unit 50 in the Z1 direction from going around to the Z2 direction of the speaker unit 50.

Further, the rigidity of the gasket 6 is greater than that of the sealing member 59. Therefore, the door trim 12 can be more firmly fixed to the mounting member 55 by the gasket 6 than in the case where the rigidity of the gasket 6 is less than the rigidity of the sealing member 59. Therefore, generation of unnecessary vibrations of the door trim 12 is suppressed. Therefore, noise is further suppressed. Note that the rigidity of the gasket 6 may be equal to or less than the rigidity of the sealing member 59.

Also in the second embodiment described above, noise can be suppressed similarly to the first embodiment. Therefore, the quality of the sound generated from the audio device 5A can be improved.

2. Modifications The above embodiments may be modified in various ways. Two or more aspects arbitrarily selected from the examples below may be combined as appropriate unless they are inconsistent.

In each embodiment, the speaker unit 50 is attached to the door trim 12 and the inner panel 13. However, the speaker unit 50 may be attached to two things other than the door trim 12 and the inner panel 13. Since the mounting member 55 has the first mounting hole 551 and the second mounting hole 552, the speaker unit 50 can be mounted on two things other than the door trim 12 and the inner panel 13. For example, the two objects include two members forming a ceiling portion of a vehicle.

In each embodiment, the speaker unit 50 is located within the opening 13a. However, the speaker unit 50 does not have to be located within the opening 13a. For example, the speaker unit 50 may be located further in the Z1 direction than the opening 13a.

In each embodiment, as shown in FIGS. 3 and 5, 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 portions that come into contact with each other, as long as they are not directly attached to each other. However, since the speaker unit 50 and the mounting member 55 are not in contact with each other, noise is further suppressed.

3. Aspects understood from at least one of the embodiment and each modification The following aspects are understood from at least one of the embodiment and each modification described above.
