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 the vibration generated by the speaker unit 50. Therefore, the vibration generated by the speaker unit 50 is reduced by the mounting member 55. Therefore, the vibration of the mounting member 55 due to the vibration of the speaker unit 50 is reduced.

Then, the 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, the vibration of the speaker unit 50 suppresses the vibration of the door trim 12. As a result, the noise generated by the vibration of the door trim 12 is suppressed. Therefore, the presence of the spring member 56 suppresses noise as compared with the case where the spring member 56 does not exist. Therefore, the sound quality of the sound generated from the audio device 5 can be improved.
  • the sealing member 57 seals between the mounting member 55 and the speaker unit 50.
  • the presence of such a sealing member 57 can prevent the sound emitted from the side opposite to the sound emitting surface 51a of the speaker unit 50 from being emitted through 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 wrapping around in the Z2 direction of the speaker unit 50.
  • the sealing member 57 has elasticity. Therefore, the sealing member 57 is elastically deformed by the vibration generated by the speaker unit 50. Therefore, the vibration generated by the speaker unit 50 is suppressed from being transmitted to the mounting member 55 via the sealing member 57.
  • the rigidity of the mounting member 55 is larger 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 in the opening 13a.
  • the gasket 6 seals between the mounting member 55 and the door trim 12.
  • the presence of such a gasket 6 suppresses the sound emitted from the speaker unit 50 from being emitted from the space S21 into the space S22. Therefore, the sound leakage of the 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.
  • the rigidity of the gasket 6 is larger than the rigidity of the sealing member 57. Therefore, the door trim 12 is firmly fixed by the mounting member 55 by the gasket 6 as compared with the case where the rigidity of the gasket 6 is equal to or less than the rigidity of the sealing member 57. Therefore, the generation of unnecessary vibration of the door trim 12 is suppressed. Therefore, noise is further suppressed.

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

　１－２．音響装置５
　図３は、図２に示す車両用ドア１００が有する音響装置５を拡大した図である。図４は、図３に示す音響装置５をＺ１方向に見た図である。図３に示す音響装置５は、開口部１３ａに対応して配置される。音響装置５は、車室内に向けて音を放出する。 1-2. Audio device 5
FIG. 3 is an enlarged view of the acoustic device 5 included in the vehicle door 100 shown in FIG. FIG. 4 is a view of the acoustic device 5 shown in FIG. 3 in the Z1 direction. The acoustic device 5 shown in FIG. 3 is arranged corresponding to the opening 13a. The sound device 5 emits sound toward the vehicle interior.
　図３および図４に示すように、音響装置５は、スピーカーユニット５０と、取付部材５５と、バネ部材５６と、密封部材５７と、を有する。なお、図３では、バネ部材５６および密封部材５７を模式的に示す。 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 FIG. 3 schematically shows the spring member 56 and the sealing member 57.
　スピーカーユニット５０は、開口部１３ａ内に位置する。スピーカーユニット５０は、ドアトリム１２およびインナーパネル１３の両方に接触していない。よって、スピーカーユニット５０は、ドアトリム１２に対して離間しており、かつインナーパネル１３に対して離間している。 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. Therefore, the speaker unit 50 is separated from the door trim 12 and separated from the inner panel 13.
　スピーカーユニット５０は、振動板５１と、フレーム５２と、駆動部５３と、ブラケット５４と、を有する。振動板５１は、車室に向けて放音する放音面５１ａを有する。放音面５１ａがドアトリム１２を向くようにスピーカーユニット５０は配置される。放音面５１ａは、空間Ｓ２１に露出している。また、振動板５１はコーン状のフレーム５２に囲まれた空間の内部に配置される。振動板５１の外縁は、フレーム５２に接続される。このため、フレーム５２は、振動板５１を振動可能に支持する。フレーム５２の材料は、例えば、金属または樹脂である。フレーム５２の外縁には、ブラケット５４が接続される。ブラケット５４の材料は、例えば、金属または樹脂である。 The speaker unit 50 has a diaphragm 51, a frame 52, a drive unit 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 in a vibrable manner. 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.
　フレーム５２の放音面５１ａの反対側（Ｚ１方向）には、駆動部５３が設けられる。駆動部５３は、例えば、磁石およびヨークを含む磁気回路と、振動板５１に接続されるボイスコイルとを含む。駆動部５３は、例えば、永久磁石で発生する磁束をヨークによりボイスコイルに導き、ボイスコイルに流れる電流により振動板５１を振動させる。駆動部５３は、図示しない回路基板から出力された音声信号に応じて振動板５１を振動させる。なお、駆動部５３の構成は、振動板５１を振動させることができれば如何なる構成でもよい。また、スピーカーユニット５０は、いわゆるコーン型であるが、その他の方式でもよい。スピーカーユニット５０は、例えばドーム型であってもよい。 A drive unit 53 is provided on the opposite side (Z1 direction) of the sound emitting surface 51a of the frame 52. 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. For example, the drive unit 53 guides the magnetic flux generated by the permanent magnet to the voice coil by the yoke, and vibrates the diaphragm 51 by the 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). The structure of the drive unit 53 may be any structure as long as the diaphragm 51 can be vibrated. The speaker unit 50 is a so-called cone type, but other methods may be used. The speaker unit 50 may be, for example, a dome shape.
　取付部材５５は、インナーパネル１３の開口部１３ａを形成する部分に接続される。図示の例では、取付部材５５は、インナーパネル１３のドアトリム１２に対向する面に接触する。取付部材５５の材料は、例えば、金属または樹脂である。取付部材５５は、環状の部材である。取付部材５５は、開口部１３ａの縁１３０ａの全周にわたって、開口部１３ａの縁１３０ａから中心に向かって張り出す。別の見方をすると、取付部材５５は、スピーカーユニット５０に対して離間し、スピーカーユニット５０からインナーパネル１３に向かって張り出す。取付部材５５は、スピーカーユニット５０に対応する開口部５５ａを有している。具体的には、開口部５５ａからスピーカーユニット５０の放音面５１ａが露出する。Ｚ１方向にみて、開口部１３ａの内側に開口部５５ａが位置し、開口部５５ａの内側にスピーカーユニット５０が位置する。開口部５５ａは、取付部材５５を貫通する孔である。取付部材５５の開口部５５ａ内に、スピーカーユニット５０が配置される。スピーカーユニット５０は、取付部材５５に接触していない。よって、スピーカーユニット５０は、取付部材５５に対して離間している。 The mounting member 55 is connected to a portion of the inner panel 13 that forms the opening 13a. In the illustrated example, the mounting member 55 contacts the 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 an annular member. The mounting member 55 projects 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 point of view, the mounting member 55 is separated from the speaker unit 50 and projects 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 that penetrates 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. Therefore, the speaker unit 50 is separated from the mounting member 55.
　取付部材５５は、スピーカーユニット５０を、ドアトリム１２およびインナーパネル１３に取り付けるための構造を有する。具体的には、取付部材５５は、複数の第１取付用孔５５１と、複数の第２取付用孔５５２とを有する。第１取付用孔５５１は、音響装置５をガスケット６を介してドアトリム１２に取り付けるための構造である。第２取付用孔５５２は、音響装置５をインナーパネル１３に取り付けるための構造である。ここで、ドアトリム１２は、２つの物のうちの一方の例示である。インナーパネル１３は、２つの物のうちの他方の例示である。 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 first mounting holes 551 and a plurality of second mounting holes 552. The first mounting hole 551 is a structure for mounting the audio device 5 to the door trim 12 via the gasket 6. The second mounting hole 552 has a structure for mounting the audio device 5 to 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.
　取付部材５５は、複数の第２固定部材２２によりインナーパネル１３に接続される。第２固定部材２２は、例えばネジである。第２固定部材２２は、第２取付用孔５５２に挿通され、かつ、インナーパネル１３が有する孔に挿入される。当該インナーパネル１３が有する孔および第２取付用孔５５２には、例えば雌ネジが形成される。 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 mounting hole 552 and is inserted into the hole of the inner panel 13. For example, a female screw is formed in the hole of the inner panel 13 and the second mounting hole 552.
　取付部材５５は、複数の第１固定部材２１によりガスケット６に接続される。第１固定部材２１は固定部材の例示である。ガスケット６は、ドアトリム１２に接続される。第１固定部材２１は、例えば樹脂製のリベットである。リベットは、ファスナーとも呼ばれる。第１固定部材２１は、例えば弾性変形した状態で第１取付用孔５５１に挿入される。 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 the fixing member. The gasket 6 is connected to the door trim 12. The first fixing member 21 is, for example, a resin rivet. Rivets are also called fasteners. The first fixing member 21 is inserted into the first mounting hole 551 in a state of being elastically deformed, for example.
　取付部材５５とスピーカーユニット５０との間には、バネ部材５６と密封部材５７とが配置される。図示の例では、密封部材５７は、バネ部材５６とドアトリム１２との間に位置する。なお、バネ部材５６は、密封部材５７とドアトリム１２との間に位置してもよい。密封部材５７とバネ部材５６とは、互いに離間している。ただし、密封部材５７の一部は、バネ部材５６に接触してもよい。 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. 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 part of the sealing member 57 may come into contact with the spring member 56.
　バネ部材５６は、取付部材５５とスピーカーユニット５０とを接続する。バネ部材５６は、環状の部材である。バネ部材５６が有する開口にスピーカーユニット５０が配置される。また、バネ部材５６は、取付部材５５およびスピーカーユニット５０のそれぞれに例えばネジにより固定される。バネ部材５６は、弾性を有する。バネ部材５６は、例えば板バネである。バネ部材５６の材料は、例えば、金属または樹脂である。 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. Further, the spring member 56 is fixed to each of the mounting member 55 and the speaker unit 50, for example, with 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.
　具体的には、図４に示す例では、バネ部材５６は、内輪５６１、外輪５６２および複数の板バネ部５６３を有する。内輪５６１は、スピーカーユニット５０に接続される。外輪５６２は、取付部材５５に接続される。複数の板バネ部５６３は、Ｚ１方向にみて、内輪５６１と外輪５６２との間に位置する。複数の板バネ部５６３は、互いに離間する。各板バネ部５６３は、弾性を有しており、内輪５６１と外輪５６２とを接続する。なお、図４に示す例では、板バネ部５６３の数は４つであるが、１つ、２つ、３つ、５つ以上でもよい。 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 portions 563. The inner ring 561 is connected to the speaker unit 50. The outer ring 562 is connected to the mounting member 55. The plurality of leaf spring portions 563 are located between the inner ring 561 and the outer ring 562 when viewed in 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 ring 561 and the outer ring 562. In the example shown in FIG. 4, the number of leaf spring portions 563 is four, but one, two, three, five or more may be used.
　なお、バネ部材５６は、板バネに限定されず、他のバネ材であってもよい。例えば、バネ部材５６は、つるまきバネでもよい。また、バネ部材５６が板バネの場合、バネ部材５６の形状は図４に示す例に限定されず、他の形状でもよい。また、バネ部材５６の数は、１個に限定されず複数でもよい。 The spring member 56 is not limited to the leaf spring, and may be another spring material. For example, the spring member 56 may be a spiral spring. Further, when 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 other shapes may be used. Further, the number of the spring members 56 is not limited to one, and may be a plurality.
　密封部材５７は、取付部材５５とスピーカーユニット５０との間を密封する。密封部材５７は、環状の部材である。密封部材５７が有する開口にスピーカーユニット５０が配置される。また、密封部材５７は、取付部材５５およびスピーカーユニット５０のそれぞれに例えばネジまたは接着剤により固定される。密封部材５７は、弾性を有する。密封部材５７は、例えばゴム膜である。なお、密封部材５７の材料は、ゴムに限定されず、樹脂等であってもよい。また、密封部材５７は、膜状に限定されず、例えばブロック状でもよい。 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. Further, the sealing member 57 is fixed to each of the mounting member 55 and the speaker unit 50 by, for example, a screw or an adhesive. The sealing member 57 has elasticity. The sealing member 57 is, for example, a rubber film. The material of the sealing member 57 is not limited to rubber, but may be resin or the like. Further, the sealing member 57 is not limited to the film shape, and may be, for example, a block shape.
　１－３．ガスケット６
　図３に示すように、ガスケット６は、取付部材５５とドアトリム１２との間に配置され、取付部材５５とドアトリム１２とに接続される。前述のように、ガスケット６は、第１固定部材２１により取付部材５５に接続される。なお、ガスケット６は、ドアトリム１２と別々に形成されて接続されてもよいし、一体で形成されてもよい。 1-3. Gasket 6
As shown in FIG. 3, the gasket 6 is arranged 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 gasket 6 is connected to the mounting member 55 by the first fixing member 21. The gasket 6 may be formed separately from the door trim 12 and connected to the gasket 6, or may be integrally formed.
　ガスケット６は、環状のシール部材である。ガスケット６は、剛性を有する。ガスケット６は、取付部材５５とドアトリム１２との間を密封する。ガスケット６は、Ｚ１方向にみて、スピーカーユニット５０と重ならず、スピーカーユニット５０を囲む。 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 in the Z1 direction, and surrounds the speaker unit 50.
　以上説明した車両用ドア１００は、前述のように、ドアトリム１２と、開口部１３ａを有するインナーパネル１３と、開口部１３ａに取り付けられた音響装置５とを備える。音響装置５は、取付部材５５と、スピーカーユニット５０と、バネ部材５６と、密封部材５７と、を有する。 As described above, the vehicle door 100 described above includes a door trim 12, an inner panel 13 having an opening 13a, and an 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.
　そして、バネ部材５６は、取付部材５５とスピーカーユニット５０とを接続する。すなわち、スピーカーユニット５０は、取付部材５５にバネ部材５６を介して接続される。このため、スピーカーユニット５０は、取付部材５５に直接的に取り付けられていない。スピーカーユニット５０が取付部材５５にバネ部材５６を介して接続されるため、スピーカーユニット５０が発する振動によって、バネ部材５６は弾性変形する。このため、スピーカーユニット５０が発する振動は、取付部材５５で低減される。よって、スピーカーユニット５０の振動によって取付部材５５が振動することが低減される。それゆえ、取付部材５５に直接的に接続されたインナーパネル１３が振動することが低減される。この結果、インナーパネル１３の振動により発生する雑音を抑制できる。 Then, 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 the vibration generated by the speaker unit 50. Therefore, the vibration generated by the speaker unit 50 is reduced by the mounting member 55. Therefore, the vibration of the mounting member 55 due to the vibration of the speaker unit 50 is reduced. Therefore, the 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.
　さらに、ガスケット６は、音響装置５とドアトリム１２とを接続する。このため、取付部材５５には、ガスケット６が直接的に接続される。そして、ガスケット６にはドアトリム１２が直接的に接続される。このため、ドアトリム１２とスピーカーユニット５０とは、バネ部材５６、取付部材５５およびガスケット６を介して接続される。ドアトリム１２とスピーカーユニット５０との接続にバネ部材５６が用いられるため、スピーカーユニット５０の振動によってドアトリム１２が振動することが抑制される。この結果、ドアトリム１２の振動により発生する雑音が抑制される。このようなことから、バネ部材５６が存在することで、バネ部材５６が存在しない場合に比べ、雑音が抑制される。それゆえ、音響装置５から発生する音の音質の向上が図られる。 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. Then, the 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, the vibration of the speaker unit 50 suppresses the vibration of the door trim 12. As a result, the noise generated by the vibration of the door trim 12 is suppressed. Therefore, the presence of the spring member 56 suppresses noise as compared with the case where the spring member 56 does not exist. Therefore, the sound quality of the sound generated from the audio device 5 can be improved.
　また、密封部材５７は、取付部材５５とスピーカーユニット５０との間を密封する。かかる密封部材５７が存在することで、スピーカーユニット５０の放音面５１ａとは反対側から放出される音が取付部材５５とスピーカーユニット５０との間を通って放出されることを防止できる。すなわち、密封部材５７が存在することで、スピーカーユニット５０のＺ１方向に放出された音がスピーカーユニット５０のＺ２方向に回り込むことが防止される。 Further, the sealing member 57 seals between the mounting member 55 and the speaker unit 50. The presence of such a sealing member 57 can prevent the sound emitted from the side opposite to the sound emitting surface 51a of the speaker unit 50 from being emitted through 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 wrapping around in the Z2 direction of the speaker unit 50.
　また、前述のように、密封部材５７は、弾性を有する。このため、スピーカーユニット５０が発する振動によって、密封部材５７は弾性変形する。よって、スピーカーユニット５０が発する振動が、密封部材５７を介して取付部材５５に伝達することが抑制される。 Further, as described above, the sealing member 57 has elasticity. Therefore, the sealing member 57 is elastically deformed by the vibration generated by the speaker unit 50. Therefore, the vibration generated by the speaker unit 50 is suppressed from being transmitted to the mounting member 55 via the sealing member 57.
　本実施形態では、取付部材５５の剛性は、密封部材５７の剛性よりも大きい。このため、取付部材５５は、スピーカーユニット５０が開口部１３ａ内に位置する状態を安定して維持できる。 In this embodiment, the rigidity of the mounting member 55 is larger 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 in the opening 13a.
　また、前述のように、ガスケット６は、取付部材５５とドアトリム１２との間を密封する。かかるガスケット６が存在することで、スピーカーユニット５０から放出される音が空間Ｓ２１から空間Ｓ２２内に放出されることが抑制される。よって、スピーカーユニット５０から発せられた音の空間Ｓ２２内への音漏れが抑制される。この結果、スピーカーユニット５０から発せられた音が複数の貫通孔１２ａを介して車室内へと効率良く放出される。 Further, as described above, the gasket 6 seals between the mounting member 55 and the door trim 12. The presence of such a gasket 6 suppresses the sound emitted from the speaker unit 50 from being emitted from the space S21 into the space S22. Therefore, the sound leakage of the 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.
　また、ガスケット６の剛性は、密封部材５７の剛性より大きい。このため、ガスケット６の剛性が密封部材５７の剛性以下である場合に比べ、ガスケット６によってドアトリム１２が取付部材５５により強固に固定される。このため、ドアトリム１２の不要な振動の発生が抑制される。それゆえ、雑音がさらに抑制される。なお、ガスケット６の剛性は、密封部材５７の剛性と同等以下でもよい。 Further, the rigidity of the gasket 6 is larger than the rigidity of the sealing member 57. Therefore, the door trim 12 is firmly fixed by the mounting member 55 by the gasket 6 as compared with the case where the rigidity of the gasket 6 is equal to or less than the rigidity of the sealing member 57. Therefore, the generation of unnecessary vibration of the door trim 12 is suppressed. Therefore, noise is further suppressed. The rigidity of the gasket 6 may be equal to or less than the rigidity of the sealing member 57.
　前述のように、ガスケット６は、第１固定部材２１を用いて取付部材５５に固定されている。具体的には、第１固定部材２１を用いてガスケット６は取付部材５５に直接的に接続される。つまり、ガスケット６と取付部材５５とは互いに接触している。このため、ガスケット６がスポンジ等の緩衝材を介して取付部材５５に接続される場合に比べ、ガスケット６によって取付部材５５とドアトリム１２との間の気密性を高めることができる。よって、音漏れがより効果的に抑制される。 As described above, the gasket 6 is fixed to the mounting member 55 by using the first fixing member 21. Specifically, the gasket 6 is directly connected to the mounting member 55 by using the first fixing member 21. That is, the gasket 6 and the mounting member 55 are in contact with each other. Therefore, the airtightness between the mounting member 55 and the door trim 12 can be improved by the gasket 6 as compared with the case where the gasket 6 is connected to the mounting member 55 via a cushioning material such as a sponge. Therefore, sound leakage is suppressed more effectively.
　また、スピーカーユニット５０と、バネ部材５６と、取付部材５５とは、開口部１３ａの中心軸Ａ１と直交する方向であるＸ軸に沿った方向に並ぶ。このため、スピーカーユニット５０と、バネ部材５６と、取付部材５５とがＸ軸に沿った方向に並ばない場合に比べ、車両用ドア１００の薄型化を図ることができる。なお、スピーカーユニット５０と、バネ部材５６と、取付部材５５とは、Ｚ軸に沿った方向からみて重ならないのであれば、Ｘ軸に沿った方向以外の方向に並んでもよい。 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 orthogonal to the central axis A1 of the opening 13a. Therefore, the vehicle door 100 can be made thinner than 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 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 each other when viewed from the direction along the Z axis.
　１－４．具体例
　図５は、第１実施形態の具体的な一態様の音響装置５ｘを示す断面図である。以下、図５を参照しつつ、音響装置５ｘが有するバネ部材５６ｘおよび密封部材５７ｘの具体的な一態様を示す。図５に示すバネ部材５６ｘは、前述のバネ部材５６に対応している。図５に示す密封部材５７ｘは、前述の密封部材５７に対応している。また、図５に示す取付部材５５ｘは、前述の取付部材５５に対応している。また、図５は、図４のＡ－Ａ線断面に対応した音響装置５の一態様である。 1-4. Specific Example FIG. 5 is a cross-sectional view showing a specific embodiment of the acoustic device 5x according to the first embodiment. Hereinafter, with reference to FIG. 5, a specific aspect of the spring member 56x and the sealing member 57x included in the audio device 5x will be shown. The spring member 56x shown in FIG. 5 corresponds to the above-mentioned spring member 56. The sealing member 57x shown in FIG. 5 corresponds to the above-mentioned sealing member 57. Further, the mounting member 55x shown in FIG. 5 corresponds to the above-mentioned mounting member 55. Further, FIG. 5 is an aspect of the acoustic device 5 corresponding to the cross section taken along the line AA of FIG.
　図５に示すように、スピーカーユニット５０の外側には、取付部材５５ｘが配置される。なお、スピーカーユニット５０が有するブラケット５４は、フレーム５２にネジ２４により固定される。 As shown in FIG. 5, a mounting member 55x is arranged on the outside of the speaker unit 50. The bracket 54 of the speaker unit 50 is fixed to the frame 52 by screws 24.
　スピーカーユニット５０と取付部材５５ｘとの間の領域には、密封部材５７ｘおよびバネ部材５６ｘが配置される。スピーカーユニット５０は、密封部材５７ｘを介して取付部材５５ｘに取り付けられる。このため、スピーカーユニット５０は、取付部材５５ｘに直接的に取り付けられていない。 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.
　バネ部材５６ｘは、ネジ２３によりスピーカーユニット５０に固定される。また、バネ部材５６ｘは、ネジ２５により取付部材５５ｘに固定される。よって、スピーカーユニット５０ｘは、バネ部材５６ｘを介して取付部材５５ｘに取り付けられている。このため、スピーカーユニット５０は、取付部材５５ｘに直接的に取り付けられていない。 The spring member 56x is fixed to the speaker unit 50 by the screw 23. Further, the spring member 56x is fixed to the mounting member 55x by the screw 25. Therefore, the speaker unit 50x is attached to the attachment member 55x via the spring member 56x. Therefore, the speaker unit 50 is not directly attached to the attachment member 55x.
　また、取付部材５５ｘは、第２固定部材２２によってインナーパネル１３に接続される。また、取付部材５５ｘは、第１固定部材２１によってガスケット６に接続される。よって、取付部材５５ｘは、ガスケット６を介してドアトリム１２に取り付けられる。 Further, the mounting 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 mounting member 55x is mounted on the door trim 12 via the gasket 6.
　また、図５に示す音響装置５ｘは、第１緩衝部材５０１と第２緩衝部材５０２とを有する。第１緩衝部材５０１は、取付部材５５ｘおよびブラケット５４と、インナーパネル１３との間に位置する。第１緩衝部材５０１は、ブラケット５４、取付部材５５ｘおよびインナーパネル１３に接触する。第１緩衝部材５０１が存在することで、第１緩衝部材５０１が存在しない場合に比べ、インナーパネル１３の振動の発生が抑制される。よって、雑音がより抑制される。 Further, the acoustic device 5x shown in FIG. 5 has 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 comes into contact with the bracket 54, the mounting member 55x, and the inner panel 13. The presence of the first cushioning member 501 suppresses the generation of vibration of the inner panel 13 as compared with the case where the first cushioning member 501 does not exist. Therefore, noise is further suppressed.
　第２緩衝部材５０２は、取付部材５５ｘとガスケット６との間に位置し、取付部材５５ｘおよびガスケット６に接触する。このため、第２緩衝部材５０２が存在することで、第２緩衝部材５０２が存在しない場合に比べ、ガスケット６を介してドアトリム１２が振動することで抑制される。よって、雑音がより抑制される。 The second cushioning member 502 is located between the mounting member 55x and the gasket 6, and comes into contact with the mounting member 55x and the gasket 6. Therefore, the presence of the second cushioning member 502 suppresses the vibration of the door trim 12 via the gasket 6 as compared with the case where the second cushioning member 502 does not exist. Therefore, noise is further suppressed.
　２．第２実施形態
　第２実施形態を説明する。以下の各例示において機能が第１実施形態と同様である要素については、第１実施形態の説明で使用した符号を流用して各々の詳細な説明を適宜に省略する。 2. 2. Second Embodiment The second embodiment will be described. For the elements having the same functions as those of the first embodiment in each of the following examples, the reference numerals used in the description of the first embodiment will be diverted and detailed description of each will be omitted as appropriate.
　図６は、第２実施形態の音響装置５Ａの概略を示す縦断面図である。第１実施形態のバネ部材５６および密封部材５７の代わりに、音響装置５Ａが密封部材５９を有すること以外、第２実施形態は第１実施形態と同じである。 FIG. 6 is a vertical sectional view showing an outline of the audio device 5A of the second embodiment. The second embodiment is the same as the first embodiment except that the acoustic device 5A has the sealing member 59 instead of the spring member 56 and the sealing member 57 of the first embodiment.
　図６に示すように、本実施形態の音響装置５Ａは、取付部材５５と、スピーカーユニット５０と、密封部材５９と、を有する。音響装置５Ａが有する密封部材５９は、スピーカーユニット５０と取付部材５５との間に位置し、スピーカーユニット５０と取付部材５５とを接続する。また、密封部材５９は、取付部材５５とスピーカーユニット５０との間を密封する。密封部材５９は、取付部材５５およびスピーカーユニット５０に例えば接着剤またはネジにより固定される。密封部材５９は、弾性を有する。密封部材５９の材料は、例えばゴムおよび樹脂である。密封部材５９は、環状の部材である。密封部材５９が有する開口にスピーカーユニット５０の一部が配置される。 As shown in FIG. 6, the audio device 5A of the present embodiment has 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, for example, with 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 of the sealing member 59.
　密封部材５９は、第１実施形態のバネ部材５６と密封部材５７の両方の機能を有する。したがって、密封部材５９は、バネ部材５６のような弾性体を有する。密封部材５９は、スピーカーユニット５０が開口部１３ａ内に位置する状態が安定して維持される。 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 such as the spring member 56. The sealing member 59 is stably maintained in a state where the speaker unit 50 is located in the opening 13a.
　本実施形態では、前述のように、スピーカーユニット５０と取付部材５５とは、密封部材５９を介して接続される。このため、スピーカーユニット５０が発する振動によって、密封部材５９は弾性変形する。したがって、スピーカーユニット５０が発する振動は、取付部材５５で低減される。よって、スピーカーユニット５０の振動によって取付部材５５が振動することが低減される。それゆえ、取付部材５５に直接的に取り付けられたインナーパネル１３が振動することが低減される。この結果、インナーパネル１３の振動により発生する雑音を抑制できる。 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 by the vibration generated by the speaker unit 50. Therefore, the vibration generated by the speaker unit 50 is reduced by the mounting member 55. Therefore, the vibration of the mounting member 55 due to the vibration of the speaker unit 50 is reduced. Therefore, the 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.
　また、ドアトリム１２とスピーカーユニット５０とは、密封部材５９およびガスケット６を介して接続される。ドアトリム１２とスピーカーユニット５０との接続に密封部材５９が用いられるため、スピーカーユニット５０の振動によってドアトリム１２が振動することが抑制される。この結果、ドアトリム１２が振動することによりビビリ音が発生することが抑制される。このようなことから、密封部材５９が存在することで、密封部材５９が存在しない場合に比べ、雑音が抑制される。 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, the vibration of the speaker unit 50 suppresses the vibration of the door trim 12. As a result, the vibration of the door trim 12 suppresses the generation of chattering noise. Therefore, the presence of the sealing member 59 suppresses noise as compared with the case where the sealing member 59 does not exist.
　また、密封部材５９は、取付部材５５とスピーカーユニット５０との間を密封する。このため、スピーカーユニット５０の放音面５１ａとは反対側から放出される音が取付部材５５とスピーカーユニット５０との間を通って放出されることを防ぐことができる。すなわち、密封部材５９が存在することで、スピーカーユニット５０のＺ１方向に放出された音がスピーカーユニット５０のＺ２方向に回り込むことを防ぐことができる。 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 being emitted through between 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 wrapping around in the Z2 direction of the speaker unit 50.
　また、ガスケット６の剛性は、密封部材５９の剛性より大きい。このため、ガスケット６の剛性が密封部材５９の剛性以下である場合に比べ、ガスケット６によってドアトリム１２を取付部材５５により強固に固定できる。このため、ドアトリム１２の不要な振動の発生が抑制される。それゆえ、雑音がさらに抑制される。なお、ガスケット６の剛性は、密封部材５９の剛性と同等以下でもよい。 Further, the rigidity of the gasket 6 is larger than the rigidity of the sealing member 59. Therefore, the door trim 12 can be firmly fixed by the mounting member 55 by the gasket 6 as compared with the case where the rigidity of the gasket 6 is equal to or less than the rigidity of the sealing member 59. Therefore, the generation of unnecessary vibration of the door trim 12 is suppressed. Therefore, noise is further suppressed. The rigidity of the gasket 6 may be equal to or less than the rigidity of the sealing member 59.
　以上の第２実施形態によっても、第１実施形態と同様に、雑音を抑制できる。それゆえ、音響装置５Ａから発生する音の音質の向上が図られる。 The noise can be suppressed by the above-mentioned second embodiment as well as the first embodiment. Therefore, the sound quality of the sound generated from the audio device 5A can be improved.
　２．変形例
　以上の実施形態は多様に変形され得る。以下の例示から任意に選択された２以上の態様は相矛盾しない限り適宜に併合され得る。 2. 2. Modifications The above embodiments can be variously modified. Two or more embodiments arbitrarily selected from the following examples can be appropriately merged as long as they do not conflict with each other.
　各実施形態では、スピーカーユニット５０は、ドアトリム１２およびインナーパネル１３に取り付けられている。しかし、スピーカーユニット５０は、ドアトリム１２およびインナーパネル１３以外の他の２つの物に取り付けられてもよい。取付部材５５が第１取付用孔５５１と第２取付用孔５５２とを有するため、スピーカーユニット５０をドアトリム１２およびインナーパネル１３以外の他の２つの物に取り付け可能である。例えば、当該２つの物としては、車両の天井部分を形成する２つの部材が挙げられる。 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 objects 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 objects other than the door trim 12 and the inner panel 13. For example, the two objects include two members forming the ceiling portion of the vehicle.
　各実施形態では、スピーカーユニット５０は、開口部１３ａ内に位置する。しかし、スピーカーユニット５０は、開口部１３ａ内に位置していなくてもよい。例えば、スピーカーユニット５０は、開口部１３ａよりもＺ１方向に位置してもよい。 In each embodiment, the speaker unit 50 is located in the opening 13a. However, the speaker unit 50 does not have to be located in the opening 13a. For example, the speaker unit 50 may be located in the Z1 direction with respect to the opening 13a.
　各実施形態では、図３および図５に示すように、スピーカーユニット５０と取付部材５５とは、互いに接触していない。しかし、スピーカーユニット５０と取付部材５５とは、互いに直接的に取り付けられていなければ、互いに接触する部分を有してもよい。ただし、スピーカーユニット５０と取付部材５５とが互いに接触していないことで、雑音がより抑制される。 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 if they are not directly mounted on each other. However, since the speaker unit 50 and the mounting member 55 are not in contact with each other, noise is further suppressed.
