Description

Technical Field

[0001] The present invention relates to an electronic device for a motor vehicle. Background Art

[0002] Conventionally, active noise control (ANC) has been implemented to cancel out noise (sound) within the interior of a motor vehicle, for example. This ANC utilizes a microphone component to receive the interior noise and output a sound with a phase opposite to the received noise, thereby canceling out the interior noise. The microphone component that receives the interior noise is, for example, attached to a headliner (hereinafter sometimes referred to as an interior trim) located on the ceiling of the vehicle interior.

[0003] Specifically, the microphone body of the microphone member is housed in a housing of the microphone member. The housing of the microphone member is positioned in the outdoor space of the vehicle interior relative to the roof lining, and the cover of the microphone member is positioned in the indoor space relative to the roof lining. The cover and housing are attached to the roof lining in a manner that sandwiches the roof lining (for example, see Japanese Patent Application Laid-Open No. 2021-78079 (hereinafter referred to as Patent Document 1)). Summary of the Invention

[0004] Here, roof side rails are provided on the vehicle widthwise outer sides of the vehicle interior ceiling, and side curtain airbags are provided on the roof side rails. When the side curtain airbag body is deployed, the deployment force of the side curtain airbag body pushes down the roof lining and deploys into the interior space.

[0005] The microphone member of Patent Document 1 is, for example, considered to be mounted in a portion of the roof lining close to the roof side rail. In this state, if the roof lining is depressed by the deployment force of the airbag body, the amount of depression (i.e., displacement) of the roof lining on the side of the roof side rail relative to the microphone member is greater than that on the side of the roof side rail opposite the roof side rail. Consequently, there is a possibility that the cover may detach from the housing and the roof lining, falling into the interior space.

[0006] As a countermeasure to prevent the cover from detaching from the housing or roof lining, one approach is to secure the cover to the housing or roof lining using brackets, adhesives, or the like. However, using brackets, adhesives, or the like to secure the cover to the housing or roof lining increases the number of components, hindering structural simplification and weight reduction.

[0007] The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide an automotive electronic device capable of preventing a cover from falling off with a simple structure.

[0008] In order to solve the above-mentioned problems and achieve the relevant objects, the present invention adopts the following means.

[0009] (1) An electronic device for a motor vehicle according to one embodiment of the present invention comprises: an electronic device located in a through-hole of an interior component provided in a vehicle cabin and arranged in the interior space of the vehicle cabin, and arranged in the outdoor space of the vehicle cabin; and a cover located in the through-hole of the interior component and engaged with the electronic device in a state of being arranged in the indoor space, the cover comprising: an engaging portion engaged with the electronic device; a strip portion passing through the through-hole and provided in the outdoor space; and a hook portion formed on the strip portion, passing through the through-hole, and hooked to the electronic device.

[0010] Here, for example, when a side curtain airbag body provided on a roof side rail is deployed, the deployment force of the airbag body may push down the interior member and disengage the cover from the electronic device.

[0011] Therefore, in this structure, the cover has a strap portion, and a hook portion is formed at the front end of the strap portion. The hook portion and the strap portion are passed through the through hole and installed in an outdoor space, and the hook portion is hooked on the electronic device.

[0012] Therefore, even if the interior part is pressed down and the cover and the electronic device are disengaged, the hook portion of the strap portion can be kept hooked on the electronic device. Thus, the strap portion and the hook portion can prevent the cover from falling into the room.

[0013] By forming a hook portion at the front end of the strip and hooking the hook portion to the electronic device, the cover can be prevented from falling into the indoor space with a simple structure without using brackets, adhesives, etc. This can suppress the increase in the number of components, achieve a simple structure and achieve weight reduction.

[0014] (2): Based on the above-mentioned solution (1), the electronic device may also include: an electronic device body; a shell that accommodates the electronic device body and is engaged with the engaging portion; and a wiring harness that is connected to the electronic device body, and the hook portion has a wiring harness through hole for the wiring harness to pass through.

[0015] According to this solution, a wire harness passes through the wire harness through-hole in the hook portion. This wire harness is connected to the electronic device body, which is housed in a housing. Therefore, even if the interior component is pressed down and the cover and the electronic device are disengaged, the hook portion can remain engaged with the wire harness and the housing. Thus, the strap and hook portion can reliably prevent the cover from falling into the interior space.

[0016] (3): Based on the above-mentioned scheme (1) or (2), the hook portion may be formed into a rectangle and have a connecting side connected to the strip portion and a side on the opposite side of the strip portion, the connecting side is located closer to the indoor space side than the side on the opposite side of the strip portion, and both end portions of the connecting side are formed as protruding angular protrusions than both end portions of the side on the opposite side of the strip portion.

[0017] Here, if the cover and the electronic device are disengaged, the connecting edge of the hook portion connected to the strip portion is pressed against the interior component. Here, in this solution, the connecting edge is located closer to the indoor space than the edge on the opposite side of the strip portion, and the two ends of the connecting edge are formed to protrude in the shape of angles compared to the two ends of the opposite side. Therefore, even if the cover and the electronic device are disengaged, the connecting edge can be pressed against the interior component, making it easy to hook the two ends of the connecting edge to the interior component. In this way, the hook portion can reliably prevent the cover from falling into the indoor space.

[0018] (4): Based on any one of the above schemes (1) to (3), the hook portion may be formed into a rectangle and have a connecting side connected to the strip portion, the through hole may be formed into a rectangle and have a pair of long sides and a pair of short sides, the connecting side may be formed to be longer than the short side of the through hole and shorter than the diagonal of the through hole, and may be arranged to cross the long side when the cover is installed on the electronic device.

[0019] According to this solution, the hook portion's connecting edge is formed to be longer than the short side of the through-hole and, when the cover is attached to the electronic device, is arranged to intersect the long side of the through-hole. Therefore, even if the cover and the electronic device become disengaged, the connecting edge can be prevented from slipping out of the through-hole into the interior space. This allows the connecting edge to be securely hooked to the interior component, while the hook portion reliably prevents the cover from falling into the interior space.

[0020] The connecting edge of the hook portion is formed shorter than the diagonal line of the through-hole. Therefore, when the cover is fitted to the electronic device, the hook portion can be passed through the through-hole along the diagonal line of the through-hole, making it easier to move the hook portion from an indoor space to an outdoor space. This improves the ease of fitting the cover to the electronic device.

[0021] (5): Based on any one of the above schemes (1) to (4), the cover may also have a flange portion, which extends outward along the interior part than the through hole, and when the cover is installed, the flange portion and the strip portion together clamp the interior part.

[0022] According to this solution, the cover has a flange, and the flange and straps sandwich the internal components. Therefore, even if the cover and the electronic device become disengaged, the flange and straps can still secure the cover to the internal components. This reliably prevents the cover from falling into the interior space.

[0023] (6): Based on any one of the above schemes (1) to (5), the electronic device for a motor vehicle may also include a buffer member arranged between the cover and the electronic device, and the buffer member has a notch for configuring the strip portion when the cover is engaged with the electronic device.

[0024] According to this embodiment, a buffer member is provided between the cover and the electronic device. Furthermore, a notch is formed in the buffer member for arranging the strip portion. Therefore, when the cover is fitted to the electronic device, the strip portion can be arranged in the notch and passed through the buffer member.

[0025] Thus, when the cover is fitted (installed) on the electronic device, the strip portion can be positioned in the installation position without being obstructed by the buffer member. By forming a notch in the buffer member, it is possible to avoid compromising the installation of the cover on the electronic device. In other words, the installation workability of the cover on the electronic device can be improved.

[0026] (7): Based on the above solution (1), (2), or (6), the electronic device may be a microphone component.

[0027] According to this aspect, by using the electronic device as a microphone member, the strap portion and the hook portion can prevent the cover fitted to the microphone member from falling out into the room, thereby improving the workability of fitting the cover to the microphone member.

[0028] According to the aspect of the present invention, the cover has a strap portion, and a hook portion is formed at the front end of the strap portion so as to be hooked on the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following describes an automotive electronic device according to an embodiment of the present invention with reference to the accompanying drawings. In the drawings, arrow FR indicates the front of the vehicle, arrow UP indicates the upper direction of the vehicle, and arrow LH indicates the left side of the vehicle. Hereinafter, the automotive electronic device may be referred to simply as "electronic device."

[0040] <Motor Vehicle>

[0041] like Figure 1 As shown, the automobile 10 includes, for example, a roof side rail 12 , a roof lining (interior trim) 14 , a side curtain airbag 16 , and an electronic device 20 .

[0042] The roof side rails 12 extend from the rear end 22a of the front pillar 22 toward the rear of the vehicle body and are located above the front side doors 23 and the rear side doors 24. A roof panel (not shown) is provided on the roof side rails 12. The roof panel forms the ceiling of the vehicle interior 25. The roof lining 14 is provided on the surface of the roof panel that faces the interior space 26 of the vehicle interior 25. Specifically, the roof lining 14 is provided on the ceiling of the vehicle interior 25 and is positioned within the interior space 26.

[0043] like Figure 1 、 Figure 2 As shown, the roof lining 14 has a through-hole 28 for mounting the electronic device 20. The through-hole 28 is formed in a portion 14a of the roof lining 14 near the roof side rail 12. The through-hole 28 has, for example, a pair of long sides 28a and a pair of short sides 28b. Specifically, the through-hole 28 is formed into a rectangular shape by the pair of long sides 28a and the pair of short sides 28b. For example, the pair of long sides 28a of the through-hole 28 face the vehicle width direction, while the pair of short sides 28b face the vehicle front-rear direction. The through-hole 28 will be described in detail later.

[0044] like Figure 1 As shown, a side curtain airbag 16 is provided on the roof side rail 12 between the roof lining 14 and the roof panel (not shown). The side curtain airbag 16 deploys an airbag member 29 during, for example, a side collision. The deployment force of the airbag member 29 pushes down the roof lining 14. As the roof lining 14 is pushed down, the airbag member 29 deploys downward from the gap between the roof lining 14 and the roof side rail 12.

[0045] Specifically, the airbag member 29 deploys along the front side door 23 and the rear side door 24 into the interior space 26. Thus, the airbag member 29 is positioned to the side of the occupant. Thus, the deployed airbag member 29 restrains the occupant's upper body (particularly the head), thereby ensuring the occupant's safety.

[0046] <Electronic equipment>

[0047] like Figures 3 to 5 As shown, the electronic device 20 is used in the vehicle compartment 25 (see Figure 1 ) of the roof lining 14 of the roof near the roof side rail 12 (refer to Figure 1 ) is mounted through the through hole 28 formed in the portion 14a. The electronic device 20 includes an electronic device 32, a cover 33, and a buffer member 34 (see also Figure 10 ).

[0048] <Electronic device (microphone component)>

[0049] The electronic device 32 is located in the through-hole 28 of the headliner 14 and is disposed in the outdoor space 27 of the vehicle interior 25. In the embodiments, the electronic device 32 is described using a microphone member as an example. However, the electronic device 32 is not limited to a microphone member. Hereinafter, the electronic device 32 may also be referred to as the "microphone member 32."

[0050] Microphone assembly 32 includes a microphone body (electronic device body) 36, a housing 37, and a wiring harness 38. Microphone body 36 is housed in housing 37 and assembled to circuit board 41. Microphone body 36 is positioned in outdoor space 27 via housing 37. Microphone body 36 may be, for example, a MEMS (Micro Electro Mechanical Systems) microphone, a dynamic microphone, a ribbon microphone, a condenser microphone, or a piezoelectric microphone. A substrate sound hole 42 is formed in circuit board 41. Substrate sound hole 42 communicates with microphone body 36.

[0051] The housing 37 is, for example, a resin member that houses the microphone body 36. The housing 37 is disposed in the outdoor space 27 on the roof lining 14. The housing 37 has a connecting portion 45 at the bottom 37a. The connecting portion 45 is located in the through-hole 28 and is inserted into the through-hole 28 from the outdoor space 27. The connecting portion 45 includes, for example, a pair of first locking claws 46 and a housing sound hole 47.

[0052] The pair of first locking claws 46 are locked to a fitting portion 62 of the cover 33 described later. The housing sound hole 47 communicates with the substrate sound hole 42 of the circuit board 41. The fitting portion 62 of the cover 33 described later is fitted into the connecting portion 45.

[0053] The wiring harness 38 includes a wiring harness body 51 and a connector 52. The distal end of the wiring harness body 51 is connected to the connector 52. The connector 52, when inserted into the insertion port 54 of the housing 37, is connected to a connection terminal 55. The connection terminal 55 is connected to the circuit board 41. In other words, the wiring harness 38 is connected to the microphone body 36 via the connection terminal 55 and the circuit board 41.

[0054] The microphone member 32 thus configured converts noise (sound) received by the microphone body 36 into an electrical signal and outputs the converted noise to the outside via the circuit board 41 and the harness 38. An example of canceling noise in the indoor space 26 using the microphone member 32 will be described in detail later.

[0055] <Cover>

[0056] like Figures 4 to 6 As shown, the cover 33 is attached to the microphone member 32. The cover 33 is attached to the microphone member 32 by being fitted into the connecting portion 45 of the housing 37 via the fitting portion 62 from the interior space 26.

[0057] The cover 33 includes a main body 61, a fitting portion 62, a strap 63, a hook portion 64, and a flange 65. The main body 61 is formed into a disk shape and has a cover sound hole 67 at its center. The fitting portion 62 protrudes upward from the back surface 61a of the main body 61. The fitting portion 62 is inserted into the through-hole 28 of the roof lining 14 and fits into the connecting portion 45 of the housing 37. The fitting portion 62 includes, for example, a pair of second locking claws 71 and a pair of locking portions 72.

[0058] The pair of second locking claws 71 are locked to the back surface 14b of the headlining 14 when the fitting portion 62 is inserted into the through hole 28 of the headlining 14 and fitted to the connecting portion 45 of the housing 37. Thus, the cover 33 is attached to the headlining 14.

[0059] The pair of locking portions 72 are locked to the pair of first locking claws 46 of the housing 37 (specifically, the connecting portion 45) when the fitting portion 62 is fitted into the connecting portion 45 of the housing 37. The pair of first locking claws 46 are locked to the pair of locking portions 72, thereby locking the main body 61 to the housing 37 (i.e., the microphone member 32).

[0060] Thus, the microphone member 32 and the main body 61 are supported in a state of being attached to the roof headlining 14. In this state, the main body 61 is positioned in the through hole 28 of the roof headlining 14 and is disposed in the interior space 26.

[0061] like Figures 5 to 7 As shown, a strip portion 63 is integrally formed on the back surface 61a of the main body 61. The strip portion 63 extends from the outer locking portion 72 in the vehicle width direction of the pair of locking portions 72 toward, for example, the roof side rail 12 (i.e., the side curtain airbag 16 before deployment) (see FIG. Figure 1 ) extends in a ribbon-like manner.

[0062] The strip portion 63 is formed so as to be able to Figure 4 ) passes through the through-hole 28 of the roof lining 14 toward the outdoor space 27. The strip portion 63 formed in this way passes through the through-hole 28 from the indoor space 26 and is arranged in the outdoor space 27.

[0063] like Figure 3 、 Figure 8 As shown, a hook portion 64 is formed at the front end portion 63a of the strip portion 63. The hook portion 64 is formed so as to be Figure 4 ) is hooked on the microphone component 32 while passing through the through hole 28 of the roof lining 14 toward the outdoor space 27.

[0064] Specifically, the hook portion 64 has a rectangular shape with four sides and has a harness through hole 75 therein. The harness through hole 75 is formed along the outer shape of the hook portion 64 so as to allow the harness 38 (i.e., the connector 52 and the harness body 51) to pass therethrough.

[0065] The hook portion 64 has four sides forming a rectangular shape, namely, a connecting side 76, a pair of side sides 77, and a free side 78. The center 76a of the connecting side 76 is connected to the front end 63a of the strip portion 63, and the connecting side 76 is formed to intersect with the strip portion 63 (in the embodiment, the connecting side 76 is described as being perpendicular to the strip portion 63). The pair of side sides 77 extend from the two end portions 76b of the connecting side 76 to the opposite side of the strip portion 63 (the side opposite to the indoor space 26). The two end portions 78a of the free side 78 are connected to the front end portions of the pair of side sides 77, and the free side 78 forms the side opposite to the strip portion 63. In other words, the connecting side 76 is located closer to the indoor space 26 side than the side opposite to the strip portion 63 (the free side 78).

[0066] In the hook portion 64 formed in this manner, both end portions 76 b of the connecting side 76 are formed to protrude in a horn-like shape relative to both end portions 78 a of the free side 78 .

[0067] like Figure 2 、 Figure 8 、 Figure 9 As shown, the through-hole 28 of the headliner 14 is formed into a rectangular shape with a pair of long sides 28a and a pair of short sides 28b. The connecting side 76 is formed to be longer than the short sides 28b of the through-hole 28 and shorter than the diagonal line 81 of the through-hole 28. Furthermore, the connecting side 76 is arranged to intersect with the long sides 28a (in the embodiment, the connection is described as being perpendicular) when the cover 33 is attached to the microphone member 32 and the headliner 14.

[0068] like Figure 4 As shown, the hook portion 64 is placed in the outdoor space 27 from the indoor space 26 through the through hole 28 , and the harness 38 (specifically, the connector 52 and the harness body 51 ) passes through the harness through hole 75 .

[0069] like Figure 4 、 Figure 6 As shown, a flange portion 65 is formed along the outer periphery 61b of the main body 61. The flange portion 65 annularly extends from the outer periphery 61b of the main body 61 along the surface 14c of the roof headlining 14, radially outward from the through-hole 28. The cover body 66 is formed into a circular plate shape by the flange portion 65 and the main body 61. When the main body 61 is attached to the roof headlining 14 and the microphone member 32, the cover body 66, together with the base end portion 63b of the strap portion 63, vertically sandwiches the roof headlining 14.

[0070] like Figure 4 、 Figure 10 As shown, the cushioning member 34 is disposed between the cover body 66 and the microphone member 32. Specifically, when the cover 33 is attached to the roof lining 14 and the microphone member 32, the cushioning member 34 is sandwiched between the cover body 66 and the housing 37 via the roof lining 14. In this state, the cushioning member 34 is held in a vertically compressed state by the cover body 66 and the housing 37.

[0071] The cushioning member 34 is formed in an annular shape along the outer periphery of the connecting portion 45 of the housing 37, and has a notch 85 formed at a position corresponding to the strap portion 63. Therefore, the strap portion 63 is disposed in the notch 85 when the headliner 14 and the microphone member 32 are attached to the cover 33.

[0072] <Microphone component operation description>

[0073] Then, based on Figure 4 An example of canceling noise in the indoor space 26 using the microphone member 32 according to the embodiment will be described.

[0074] like Figure 4 As shown, when the electronic device 20 is mounted on the headliner 14, the cover sound hole 67, the housing sound hole 47, and the base sound hole 42 are in communication. The base sound hole 42 is in communication with the microphone body 36. Noise (sound) in the interior space 26 is transmitted to the microphone body 36 via the cover sound hole 67, the housing sound hole 47, and the base sound hole 42, and the transmitted noise is received by the microphone body 36.

[0075] Noise received by microphone body 36 is converted into an electrical signal and output to the outside as sound with an opposite phase to the noise via circuit board 41 and harness 38. This allows active noise control (ANC) to be implemented in indoor space 26, allowing the sound with the opposite phase to cancel out the noise in indoor space 26.

[0076] As described above, according to the electronic device 20 of the embodiment, Figure 1 、 Figure 4 、 Figure 5 As shown, the airbag member 29 of the side curtain airbag 16 mounted on the roof side rail 12 deploys. At this time, for example, the deploying force of the airbag member 29 causes a portion 14a of the roof headliner 14, located near the roof side rail 12 (i.e., the side curtain airbag 16), to be depressed as indicated by arrow A. Specifically, the amount of depression (i.e., displacement) of the roof headliner 14 on the side of the roof side rail 12 opposite the electronic device 20 is greater than that of the roof headliner 14 on the side of the roof side rail 12 opposite the electronic device 20.

[0077] Therefore, the first locking claw 46 of the connecting portion 45 is expected to be disengaged from the locking portion 72 of the fitting portion 62, and the second locking claw 71 is expected to be disengaged from the roof headlining 14. In this case, the cover 33 is expected to be disengaged from the microphone member 32 and the roof headlining 14, and fall into the interior space 26.

[0078] Here, the strap portion 63 extends from the cover 33 (specifically, the back surface 61a of the main body 61), and a hook portion 64 is formed at the front end 63a of the strap portion 63. The hook portion 64 and the strap portion 63 are passed through the through-hole 28 from the indoor space 26 and installed in the outdoor space 27. In this state, the wire harness 38 (i.e., the connector 52 and the wire harness main body 51) passes through the wire harness through-hole 75 of the hook portion 64.

[0079] The connector 52 is inserted into the insertion port 54 of the housing 37 while passing through the harness through hole 75 of the hook portion 64, and is connected to the circuit board 41 via the connection terminal 55. Thus, the hook portion 64 is held in a state of being hooked to the harness 38 of the microphone member 32 (i.e., the connector 52 and the harness body 51).

[0080] Therefore, even if the headliner 14 is pushed down as indicated by arrow A and the cover 33 is separated from the microphone member 32 and the headliner 14, the hook portion 64 of the strap portion 63 can be kept hooked on the wire harness 38. Thus, the strap portion 63 and the hook portion 64 can prevent the cover 33 from falling into the interior space 26.

[0081] By forming the hook portion 64 at the front end portion 63a of the strap portion 63 and hooking the hook portion 64 onto the wire harness 38, it is possible to prevent the cover 33 from falling into the interior space 26 with a simple structure without using a bracket, adhesive, etc. This can suppress an increase in the number of components in the electronic device 20, achieve a simplified structure, and achieve weight reduction.

[0082] Furthermore, with the wire harness 38 inserted through the wire harness through-hole 75 of the hook portion 64, the connector 52 of the wire harness 38 is connected to the microphone body 36 via the circuit board 41 or the like. The microphone body 36 is housed in the housing 37. Therefore, even if the headliner 14 is pushed down as indicated by arrow A and the cover 33 is detached from the microphone member 32 and the headliner 14, the hook portion 64 can be retained in the state of being engaged with the wire harness 38 and the housing 37. Thus, the strap portion 63 and the hook portion 64 can reliably prevent the cover 33 from falling into the interior space 26.

[0083] In addition, if Figure 4 、 Figure 8As shown, if the cover 33 detaches from the microphone member 32 and the roof lining 14, the connecting edge 76 of the hook portion 64, which is connected to the strip portion 63, presses against the roof lining 14. Here, the connecting edge 76 is positioned closer to the interior space 26 than the free edge 78, and the ends 76b of the connecting edge 76 are formed to protrude in a angular manner relative to the ends 78a of the opposite free edge 78. Therefore, even if the cover 33 detaches from the microphone member 32 and the roof lining 14, the pressing of the connecting edge 76 against the roof lining 14 allows the ends 76b of the connecting edge 76 to be easily hooked to the roof lining 14. Thus, the hook portion 64 reliably prevents the cover 33 from falling into the interior space 26.

[0084] like Figure 4 、 Figure 8 、 Figure 9 As shown, the connecting edge 76 of the hook portion 64 is formed to be longer than the short side 28b of the through-hole 28. When the cover 33 is attached to the microphone member 32 and the roof lining 14, the connecting edge 76 is arranged to intersect (specifically, be perpendicular to) the long side 28a of the through-hole 28. Therefore, even if the cover 33 detaches from the microphone member 32 and the roof lining 14, the connecting edge 76 is prevented from slipping out of the through-hole 28 into the interior space 26. This ensures that the connecting edge 76 is securely hooked to the roof lining 14, and the hook portion 64 reliably prevents the cover 33 from falling into the interior space 26.

[0085] Furthermore, the connecting side 76 of the hook portion 64 is formed shorter than the diagonal line 81 of the through-hole 28. Therefore, when the cover 33 is fitted to the microphone member 32, the hook portion 64 is passed through the through-hole 28 along the diagonal line 81 of the through-hole 28, making it easier to move the hook portion 64 from the interior space 26 to the exterior space 27. This allows the cover 33 to be fitted to the microphone member 32 and installed, improving the ease of installation on the roof lining 14.

[0086] In addition, if Figure 4 、 Figure 6 As shown, the flange portion 65 extends annularly from the outer periphery of the main body 61 of the cover body 66, and the cover body 66 and the base end portion 63b of the strap portion 63 sandwich the roof lining 14 in the vertical direction. Therefore, even if the cover 33 detaches from the microphone member 32 and the roof lining 14, the cover body 66 and the strap portion 63 can retain the cover 33 on the roof lining 14. This reliably prevents the cover 33 from falling into the interior space 26.

[0087] like Figure 4 、 Figure 10As shown, a buffer member 34 is provided that is sandwiched between the cover body 66 and the housing 37 via the roof lining 14 when the cover 33 is attached to the roof lining 14 and the microphone member 32. Furthermore, a notch 85 is formed in the buffer member 34 for receiving the strap portion 63. Therefore, with the cover 33 attached to the roof lining 14 and the microphone member 32, the strap portion 63 can be positioned in the notch 85 and passed through the buffer member 34.

[0088] Thus, when the cover 33 is mounted on the roof lining 14 and the microphone member 32, the strip portion 63 can be positioned in the mounting position without being obstructed by the buffer member 34. Thus, by forming the notch 85 in the buffer member 34, the mounting performance of the cover 33 on the roof lining 14 and the microphone member 32 can be prevented from being impaired. In other words, the mounting workability of the cover 33 by fitting it into the microphone member 32 can be improved.

[0089] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0090] In the above embodiment, the microphone member 32 is attached to the ceiling of the vehicle interior 25 formed by the roof lining 14 , but the present invention is not limited thereto.

[0091] In addition, within the scope not departing from the gist of the present invention, components in the above-described embodiments may be appropriately replaced with well-known components, and the above-described modifications may be appropriately combined.
