1-2. Sound equipment 5

Fig. 3 is an enlarged view of the acoustic device 5 included in the vehicle door 100 shown in fig. 2. Fig. 4 is a view of the acoustic device 5 shown in fig. 3 as viewed from the Z1 direction. The acoustic device 5 shown in fig. 3 is disposed corresponding to the opening 13a. The acoustic device 5 emits sound into the vehicle interior.

As shown in fig. 3 and 4, the acoustic device 5 includes a speaker unit 50, a mounting member 55, a spring member 56, and a sealing member 57. In fig. 3, a spring member 56 and a seal member 57 are schematically shown.

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

The speaker unit 50 has a diaphragm 51, a frame 52, a driving portion 53, and a bracket 54. The diaphragm 51 has a sound emitting surface 51a for emitting sound toward the vehicle cabin. The speaker unit 50 is disposed with the sound emitting surface 51a facing the door trim 12. The playback surface 51a is exposed to the space S21. The diaphragm 51 is disposed in a space surrounded by a conical (cone) frame 52. The outer edge of the vibration plate 51 is connected to the frame 52. Accordingly, the frame 52 supports the vibration plate 51 to be vibratable. The material of the frame 52 is, for example, metal or resin. Brackets 54 are attached to the outer edges of the frame 52. The material of the bracket 54 is, for example, metal or resin.

A driving unit 53 is provided on the opposite side (Z1 direction) of the playback 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 diaphragm 51. The driving unit 53 guides magnetic flux generated by the permanent magnet to the voice coil through the yoke, for example, and vibrates the diaphragm 51 by a current flowing through the voice coil. The driving unit 53 vibrates the vibration plate 51 in accordance with an audio signal output from a circuit board not shown. The driving unit 53 may be any structure as long as it can vibrate the vibration plate 51. The speaker unit 50 may be a so-called cone type, or may be another type. The speaker unit 50 may be, for example, a dome type.

The mounting member 55 is connected to a portion of the inner panel 13 where the opening 13a is formed. In the illustrated example, the mounting member 55 is in contact with a surface of the inner panel 13 facing the door trim 12. The material of the mounting member 55 is, for example, metal or resin. The mounting member 55 is a ring-shaped member. The attachment member 55 extends from the edge 130a of the opening 13a toward the center over the entire periphery of the edge 130a of the opening 13a. In other words, the mounting member 55 is separated from the speaker unit 50, and protrudes 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 reproduction surface 51a of the speaker unit 50 is exposed from the opening 55a. The opening 55a is located inside the opening 13a as viewed in the Z1 direction, and the speaker unit 50 is located inside the opening 55a. The opening 55a is a hole penetrating the mounting member 55. The speaker unit 50 is disposed in the opening 55a of the mounting member 55. The speaker unit 50 is not in contact with the mounting member 55. Thereby, the speaker unit 50 is separated from the mounting member 55.

The mounting member 55 has a structure for mounting the speaker unit 50 to the door trim 12 and the inner panel 13. Specifically, the mounting member 55 has a plurality of 1 st mounting holes 551 and a plurality of 2 nd mounting holes 552. The 1 st mounting hole 551 is a structure for mounting the acoustic device 5 to the door trim 12 via the pad 6. The 2 nd mounting hole 552 is a structure for mounting the acoustic device 5 to the inner panel 13. Here, the door trim 12 is an illustration of one of 2 items. The inner panel 13 is an illustration of another of the 2 items.

The mounting member 55 is connected to the inner panel 13 by a plurality of 2 nd fixing members 22. The 2 nd fixing member 22 is, for example, a screw. The 2 nd fixing member 22 is inserted through the 2 nd mounting hole 552 and is inserted into a hole provided in the inner panel 13. For example, female screws are formed in the holes of the inner panel 13 and the 2 nd mounting holes 552.

The mounting member 55 is connected to the pad 6 by a plurality of 1 st fixing members 21. The 1 st fixing member 21 is an example of a fixing member. The cushion 6 is connected to the door trim 12. The 1 st fixing member 21 is, for example, a rivet made of resin. Rivets are also known as fasteners. The 1 st fixing member 21 is inserted into the 1 st mounting hole 551 in an elastically deformed state, for example.

A spring member 56 and a seal member 57 are disposed 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. In addition, the spring member 56 may also be located between the seal member 57 and the door trim 12. The sealing member 57 and the spring member 56 are separated from each other. However, a part of the seal 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 a ring-shaped member. The speaker unit 50 is disposed in an opening provided in the spring member 56. The spring member 56 is fixed to the mounting member 55 and the speaker unit 50 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.

Specifically, in the example shown in fig. 4, the spring member 56 includes an inner ring 561, an outer ring 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 as viewed in the Z1 direction. The plurality of plate spring portions 563 are separated 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 plate spring portions 563 is 4, but 1, 2, 3, 5 or more plate spring portions may be used.

The spring member 56 is not limited to a leaf spring, and may be another spring member. For example, the spring member 56 may be a coil spring. In the case where the spring member 56 is a leaf spring, the shape of the spring member 56 is not limited to the example shown in fig. 4, and may be other shapes. The number of the spring members 56 is not limited to 1, and may be plural.

The sealing member 57 seals between the mounting member 55 and the speaker unit 50. The seal member 57 is an annular member. The speaker unit 50 is disposed in an opening provided in the sealing member 57. The sealing member 57 is fixed to the mounting member 55 and the speaker unit 50 by, for example, screws or an adhesive. The seal member 57 has elasticity. The sealing member 57 is, for example, a rubber film. The material of the seal member 57 is not limited to rubber, and may be resin or the like. 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 described above, the pad 6 is connected to the mounting member 55 via the 1 st fixing member 21. The cushion 6 may be formed separately from the door trim 12, or may be integrally formed.

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.

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

Further, 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 to the mounting member 55. The speaker unit 50 is connected to the mounting member 55 via the spring member 56, and thus the spring member 56 is elastically deformed due to vibration generated by the speaker unit 50. Accordingly, the vibration generated by the speaker unit 50 is reduced at the mounting member 55. Thereby, the degree of vibration generated in the mounting member 55 due to the vibration of the speaker unit 50 is reduced. Thus, the degree of vibration of the inner panel 13 directly connected to the mounting member 55 is reduced. As a result, noise generated by the vibration of the inner panel 13 can be suppressed.

The pad 6 connects the acoustic device 5 and the door trim 12. Thus, the pad 6 is directly connected to the mounting member 55. Further, the door trim 12 is directly connected to the cushion 6. Therefore, the door trim 12 and the speaker unit 50 are connected via the spring member 56, the mounting member 55, and the cushion 6. For the connection of the door trim 12 and the speaker unit 50, the spring member 56 is used, and therefore, the occurrence of vibration of the door trim 12 due to vibration of the speaker unit 50 is suppressed. As a result, noise generated by the vibration of the door trim 12 is suppressed. According to the above, the spring member 56 is present, so that noise is suppressed as compared with the case where the spring member 56 is not present. Thus, the sound quality of the sound generated from the acoustic device 5 is improved.

In addition, the sealing member 57 seals between the mounting member 55 and the speaker unit 50. The sealing member 57 is provided to prevent sound emitted from the speaker unit 50 on the opposite side of the sound emission surface 51a from being emitted between the mounting member 55 and the speaker unit 50. That is, the sealing member 57 is provided, so that sound emitted in the Z1 direction of the speaker unit 50 can be prevented from winding around the Z2 direction of the speaker unit 50.

In addition, as described above, the seal member 57 has elasticity. Accordingly, the sealing member 57 is elastically deformed due to the vibration generated by the speaker unit 50. Thereby, the vibration generated by the speaker unit 50 is suppressed from being transmitted to the mounting member 55 via the sealing member 57.

In the present 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 positioned in the opening 13a.

In addition, as described above, the gasket 6 seals between the mounting member 55 and the door trim 12. By the presence of the pad 6, the sound emitted from the speaker unit 50 is suppressed from being emitted from the space S21 into the space S22. Thereby, sound 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.

In addition, the rigidity of the gasket 6 is greater than the rigidity of the seal member 57. Therefore, the door trim 12 is more firmly fixed to the mounting member 55 by the cushion 6 than in the case where the rigidity of the cushion 6 is equal to or less than the rigidity of the seal member 57. Therefore, the occurrence of unnecessary vibration of the door trim 12 is suppressed. Thus, noise is further suppressed. The rigidity of the gasket 6 may be equal to or lower than the rigidity of the seal member 57.

As described above, the pad 6 is fixed to the mounting member 55 by using the 1 st fixing member 21. Specifically, the 1 st fixing member 21 is used to directly connect the pad 6 to the mounting member 55. That is, the pad 6 and the mounting member 55 are in contact with each other. Therefore, compared with the case where the cushion 6 is connected to the mounting member 55 via a cushioning material such as a sponge, the air tightness between the mounting member 55 and the door trim 12 can be improved by the cushion 6. Thereby, sound leakage is more effectively suppressed.

The speaker unit 50, the spring member 56, and the mounting member 55 are arranged in a direction along an X-axis, which is a direction orthogonal to the central axis A1 of the opening 13a. Therefore, the vehicle door 100 can be thinned as compared with a case where the speaker unit 50, the spring member 56, and the mounting member 55 are not aligned in the direction along the X axis. 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 in the direction along the Z axis.

1-4. Specific example

Fig. 5 is a cross-sectional view showing an acoustic device 5x according to a specific embodiment of embodiment 1. Next, referring to fig. 5, a specific embodiment of the spring member 56x and the seal member 57x included in the acoustic device 5x is shown. The spring member 56x shown in fig. 5 is disposed corresponding to the spring member 56 described above. The seal member 57x shown in fig. 5 is disposed corresponding to the seal member 57 described above. The mounting member 55x shown in fig. 5 is arranged corresponding to the mounting member 55. Fig. 5 is a view showing an embodiment of the acoustic device 5 corresponding to the section of the line A-A in fig. 4.

As shown in fig. 5, a mounting member 55x is disposed outside the speaker unit 50. The bracket 54 of the speaker unit 50 is fixed to the frame 52 by the screw 24.

A seal member 57x and a spring member 56x are disposed in a region between the speaker unit 50 and the mounting member 55x. The speaker unit 50 is mounted to the mounting member 55x via the sealing member 57 x. Therefore, the speaker unit 50 is not directly mounted to the mounting member 55x.

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

The mounting member 55x is connected to the inner panel 13 by the 2 nd fixing member 22. The mounting member 55x is connected to the pad 6 via the 1 st fixing member 21. Thereby, the attachment member 55x is attached to the door trim 12 via the cushion 6.

The acoustic device 5x shown in fig. 5 includes a1 st buffer member 501 and a 2 nd buffer member 502. The 1 st cushioning member 501 is located between the mounting member 55x and the bracket 54 and the inner panel 13. The 1 st cushioning member 501 contacts the bracket 54, the mounting member 55x, and the inner panel 13. The 1 st cushioning member 501 is present, so that the inner panel 13 is suppressed from vibrating as compared with the case where the 1 st cushioning member 501 is not present. Thereby, noise is further suppressed.

The 2 nd cushioning member 502 is located between the mounting member 55x and the pad 6, and contacts the mounting member 55x and the pad 6. Therefore, the 2 nd cushioning member 502 is present, and the occurrence of vibration of the door trim 12 via the cushion 6 can be suppressed as compared with the case where the 2 nd cushioning member 502 is not present. Thereby, noise is further suppressed.

2. Embodiment 2

Embodiment 2 will be described. In the following examples, the elements having the same functions as those of embodiment 1 will be appropriately omitted from detailed description along with the numerals used in the description of embodiment 1.

Fig. 6 is a schematic longitudinal sectional view showing the acoustic device 5A according to embodiment 2. Embodiment 2 is the same as embodiment 1 except that the acoustic device 5A has a seal member 59 instead of the spring member 56 and the seal member 57 of embodiment 1.

As shown in fig. 6, the acoustic device 5A of the present embodiment includes a mounting member 55, a speaker unit 50, and a sealing member 59. The sealing member 59 of the acoustic 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 or resin. The seal member 59 is an annular member. A part of the speaker unit 50 is disposed in the opening provided in the sealing member 59.

The seal member 59 has the functions of both the spring member 56 and the seal member 57 of embodiment 1. Therefore, the seal member 59 has an elastic body such as the spring member 56. The sealing member 59 stably maintains the state in which the speaker unit 50 is located in the opening 13a.

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

The door trim 12 and the speaker unit 50 are connected via the seal member 59 and the gasket 6. For the connection of the door trim 12 and the speaker unit 50, the seal member 59 is used, and thus the door trim 12 is restrained from vibrating due to the vibration of the speaker unit 50. As a result, the occurrence of chattering sound due to the vibration of the door trim 12 is suppressed. According to the above, the sealing member 59 is present, and noise is suppressed as compared with the case where the sealing member 59 is not present.

In addition, the sealing member 59 seals between the mounting member 55 and the speaker unit 50. Therefore, sound emitted from the speaker unit 50 on the opposite side of the sound emission surface 51a can be prevented from being emitted between the mounting member 55 and the speaker unit 50. That is, the sealing member 59 is provided, so that sound emitted in the Z1 direction of the speaker unit 50 can be prevented from winding into the Z2 direction of the speaker unit 50.

In addition, the rigidity of the gasket 6 is greater than that of the seal member 59. Therefore, the door trim 12 can be more firmly fixed to the mounting member 55 by the cushion 6 than in the case where the rigidity of the cushion 6 is equal to or less than the rigidity of the seal member 59. Therefore, the occurrence of unnecessary vibration of the door trim 12 is suppressed. Thus, noise is further suppressed. The rigidity of the gasket 6 may be equal to or lower than the rigidity of the seal member 59.

In embodiment 2 above, noise can be suppressed as in embodiment 1. Thus, the sound quality of the sound generated from the acoustic device 5A can be improved.

2. Modification examples

The above embodiment can be variously modified. The 2 or more ways arbitrarily selected from the following examples can be appropriately combined within a non-contradictory range.

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 2 other articles than the door trim 12 and the inner panel 13. Since the mounting member 55 has the 1 st mounting hole 551 and the 2 nd mounting hole 552, the speaker unit 50 can be mounted to 2 other objects than the door trim 12 and the inner panel 13. For example, the 2 items include 2 members forming a ceiling portion of a vehicle.

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 as compared with the opening 13a.

In each embodiment, as shown in fig. 3 and 5, the speaker unit 50 and the mounting member 55 are not in contact with each other.
