Description

  The present invention relates to a vehicle speaker mounting structure for mounting a speaker covered with a speaker grill to a vehicle.

  Many vehicles are equipped with speakers used for audio and the like. The speaker is generally covered with a speaker grille on the surface on the vehicle compartment side. Various techniques for attaching a speaker and a speaker grill to a vehicle body have been proposed (see, for example, Patent Document 1).

  In the vehicle speaker mounting structure known from Patent Document 1, the speaker is mounted on a vehicle body panel (rear parcel panel). A speaker grill for covering the speaker is attached to an interior member (rear parcel shelf). The interior member is disposed on the vehicle compartment side of the vehicle body panel and is also attached to the vehicle body panel. The speaker grille has a plurality of legs, and these legs extend from the mounting position toward the passenger compartment. A lid-like main body is formed at the tip of the leg, and the main body covers the speaker. By attaching the speaker and the speaker grill to the vehicle body panel, the distance from the speaker to the speaker grill is kept constant. Since the speaker grille is also attached to the interior member, it is not separated from the interior member.

  By the way, depending on the configuration of the vehicle body panel, the surface opposite to the interior member may be outside the vehicle. In such a case, a speaker cannot be arranged with respect to the vehicle body panel. On the other hand, it is conceivable to arrange a speaker in a space between the vehicle body panel and the interior member. However, this space is not always large enough to arrange speakers. That is, there is a limit to disposing the speaker freely at an arbitrary position on the vehicle body.

Such an interior member 22 is also called lining (garnish). The interior member 22 is separated from the vehicle body panel 21 at a predetermined interval t on the vehicle compartment 12 side. That is, a gap 23 (space 23) having a predetermined interval t is provided between the vehicle body panel 21 and the interior member 22. Hereinafter, the interior member 22 is appropriately rephrased as “lining 22”.

  The interior member 22 (including the door lining) is provided with a speaker 30 and a speaker grill 50 that covers the speaker 30. For example, the speaker 30 and the speaker grill 50 are disposed on the interior member 22 that covers the rear pillar 24. In the present invention, both the speaker 30 and the speaker grille 50 are attached only to the interior member 22. In particular, in the first embodiment, the speaker 30 is attached to the interior member 22 via the speaker grill 50. This will be described in detail below.

  As shown in FIGS. 2 and 4, the speaker 30 is configured by a cone speaker, and is used as an audio device mounted on a vehicle, for example. The speaker 30 includes a back plate 31, a pole piece 32 provided on the upper surface of the central portion of the back plate 31, a magnet 33 that surrounds the pole piece 32 and is superimposed on the upper surface of the back plate 31, and this magnet A top plate 34 superposed on the upper surface of 33, a cone-shaped frame 35 coupled to the upper surface of the top plate 34, a cone-shaped diaphragm 36 disposed in the frame 35, and the vibration plate 36. A voice coil 37 wound around the small diameter portion.

  The back plate 31, the pole piece 32, the magnet 33, and the top plate 34 constitute an outer magnet type magnetic circuit. A substantially annular flange portion 41 (attached portion 41) is integrally formed at the large-diameter end of the frame 35. The large-diameter end of the diaphragm 36 is supported on the flange portion 41 by an annular edge 42. The small-diameter end of the diaphragm 36 is supported on the frame 35 by an annular damper 43. A center cap 44 and a voice coil 37 are wound around the small diameter portion of the diaphragm 36. The voice coil 37 is positioned in a magnetic gap formed between the top plate 34 and the small diameter portion of the diaphragm 36.

  Only a part of the speaker 30 is located in the gap 23 between the vehicle body panel 21 and the interior member 22, and the remaining part projects from the interior member 22 toward the vehicle compartment 12. For example, only the magnetic circuit portion is located in the air gap 23, and the remaining frame 35 and diaphragm 36 are located in the passenger compartment 12. The lining 22 is provided with a speaker hole 26 for inserting a part of the speaker 30 from the passenger compartment 12 into the gap 23. The speaker hole 26 is set to a size that the speaker 30 does not contact.

  The speaker 30 may be an arbitrary speaker such as a dome speaker in addition to a cone speaker.

  As shown in FIGS. 2 to 4, the speaker grille 50 (speaker cover 50) is a resin member such as a hard resin formed in a generally cap shape so as to cover the speaker 30, and is manufactured by injection molding. Injection molded product. The speaker grill 50 is located closer to the vehicle compartment 12 than the interior member 22 and is overlapped with the interior member 22 with a slight gap δ. A portion of the speaker 30 located in the vehicle compartment 12 is almost completely covered by the interior member 22 and the speaker grille 50. The shape and size of the speaker grill 50 are determined in consideration of the directivity of the sound generated by the speaker 30 and the acoustic effect.

  More specifically, the speaker grill 50 includes a substantially rectangular plate-like main body 51 positioned facing the vehicle compartment 12, and a peripheral wall 52 extending from the periphery of the main body 51 toward the lining 22 over the entire circumference. Is an integrally formed product. In the center of the main body 51, a plurality of openings 53 penetrating therethrough are formed. The sound generated by the speaker 30 propagates to the vehicle compartment 12 through the plurality of openings 53. The shape and size of the speaker grill 50 and the shape and size of the opening 53 are determined in consideration of the directivity of the sound generated by the speaker 30 and the acoustic effect.

  Further, the speaker grill 50 includes at least one grill fixing boss 54 for attaching the speaker grill 50 to the lining 22, and at least one speaker fixing boss 55 for attaching the speaker 30 to the speaker grill 50. Have. Both the grill fixing boss 54 and the speaker fixing boss 55 are formed integrally with the speaker grill 50, and from the back surface 56 facing the diaphragm 36 of the speaker 30 (the back surface 56 facing the lining 22) in the speaker grill 50. It extends towards the lining 22. For this reason, the process of attaching the grill fixing boss 54 and the speaker fixing boss 55 to the speaker grill 50 can be omitted. As a result, the manufacturing cost of the speaker grill 50 can be reduced.

  There are preferably a plurality of grill fixing bosses 54 and speaker fixing bosses 55, each of which is constituted by, for example, four cylindrical members. The four grill fixing bosses 54 and the four speaker fixing bosses 55 are respectively disposed at the corners of the substantially rectangular main body 51. Specifically, the four grill fixing bosses 54 are arranged radially with respect to the central axis 57 of the speaker grill 50 and inside the peripheral wall portion 52. The four speaker fixing bosses 55 are arranged radially with respect to the central axis 57 of the speaker grill 50 and closer to the central axis 57 than the four grill fixing bosses 54.

  More specifically, as shown in FIG. 3, the four speaker fixing bosses 55 are formed on the circumference of the radius R1 from the central axis 57. The phase of each speaker fixing boss 55 is 90 °. Similarly, the four grill fixing bosses 54 are formed on the circumference of the radius R2 from the central shaft 57. The phase of each grill fixing boss 54 is 90 °. The radius R2 is larger than the radius R1.

  The two grill fixing bosses 54 are formed on a straight line 67 that passes through the central shaft 57 and the two speaker fixing bosses 55. The same applies to the remaining two grill fixing bosses 54. By forming the grill fixing boss 54 and the speaker fixing boss 55 on the same straight line with respect to the central axis 57, the grill fixing boss 54 and the speaker fixing boss 55 can be arranged close to each other. it can. A speaker fixing boss 55 is formed in the vicinity of the grill fixing boss 54 which becomes highly rigid by being attached to the lining 22, and the speaker 30 is attached to the speaker fixing boss 55. As a result, the speaker 30 can be attached in the vicinity of a highly rigid portion, which is preferable.

  As shown in FIGS. 2 and 4, the flange portion 41 of the speaker 30 is overlaid on the front end surfaces 55 a of the four speaker fixing bosses 55 via the vibration-proof washers 61, and the speaker fixing screws 62 are used. It is attached. Each anti-vibration washer 61 is an anti-vibration member made of an elastic material such as rubber for suppressing vibration transmitted between the speaker grill 50 and the speaker 30.

  As shown in FIG. 2, the distance between the speaker 30 and the speaker grille can be kept constant by each speaker fixing boss 55. The length of each speaker fixing boss 55 is set to L1. This distance L1 determines the distance from the speaker 30 to the main body 51 of the speaker grill 50. The length L1 is determined in consideration of the directivity of the sound generated by the speaker 30 and the acoustic effect.

  As shown in FIGS. 2 and 4, the front end surfaces 54 a of the four grill fixing bosses 54 are set to be flush with the front end surface 52 a of the wall portion 52. The front end surfaces 54 a of the four grill fixing bosses 54 are overlaid on the lining 22 via vibration isolating washers 63 and attached by grill fixing screws 64. Each anti-vibration washer 63 is an anti-vibration member made of an elastic material such as rubber for suppressing vibration transmitted between the lining 22 and the speaker grill 50. In the lining 22, four screw hole portions 27 for passing each grill fixing screw 64 are formed in a portion facing the grill fixing boss 54. Thus, the speaker 30 is attached to the lining 22 through the speaker grille 50 by attaching the speaker 30 to the speaker fixing boss 55 and attaching the grill fixing boss 54 to the lining 22.

  The mounting structure of each grill fixing boss 54 to the lining 22 may be a structure of riveting or a snap fit with a clip or an elastic claw in addition to the grill fixing screw 64.

  As shown in FIG. 2, the length of each grill fixing boss 54 is set to L2. The length L2 is longer than the length L1 of the speaker fixing boss 55. The length L2 of each grill fixing boss 54 is set such that the speaker 30 attached to the lining 22 via the speaker grill 50 does not come into contact with the vehicle body panel 21 located on the back surface of the lining 22. ing.

  The front end surface 55a of each speaker fixing boss 55 is a point to which the flange portion 41 (attached portion 41) of the speaker 30 is attached, that is, an attachment point. Hereinafter, the front end surface 55a of each speaker fixing boss 55 is referred to as “the attachment point 55a of the speaker 30” as appropriate. The distance from the surface of the lining 22 on the vehicle compartment 12 side to the attachment point 55a (tip surface 55a) is L3. This distance L3 substantially corresponds to the difference between the length L2 of the grill fixing boss 54 and the length L1 of the speaker fixing boss 55 (L3≈L2-L1). That is, the attachment point 55 a (tip surface 55 a) of the speaker 30 with respect to the lining 22 is located closer to the vehicle compartment 12 than the lining 22 by a distance L 3. With respect to the size of the distance L3, the rear end surface (back plate 31) of the operating speaker 30 is connected to the vehicle body panel 21 with the flange portion 41 of the speaker 30 attached to the front end surface 55a of the speaker fixing boss 55. The size is set so as not to touch. By setting the distance L3, the amount (the degree of burial) of the speaker 30 entering the space 23 between the vehicle body panel 21 and the interior member 22 is determined.

  Thus, since the attachment point 55a of the speaker 30 is located closer to the vehicle compartment 12 than the lining 22, the entire speaker 30 can be attached to the vehicle compartment 12 side. Even when the gap t between the gaps 23 between the vehicle body panel 21 and the lining 22 is narrow, the speaker 30 is attached to the vehicle compartment 12 side by setting the attachment point 55a to the vehicle compartment 12 side of the lining 22. be able to.

  In particular, it is desirable that the attachment point 55 a is set so that the portion disposed on the outermost 69 side of the speaker 30, that is, the back plate 31 is disposed closer to the vehicle compartment 12 than the body main body 21. By attaching the speaker 30 to the vehicle compartment 12 side of the body main body 21, the mounting position of the speaker 30 is not limited by the components arranged on the outer side 69 of the body main body 21. Furthermore, the freedom degree of the attachment position of the speaker 30 increases. Further, it is not necessary to process the body body 21 for attaching the speaker 30. This is particularly useful when the speaker 30 is to be mounted later.

Further, the front end surface 54 a of each grill fixing boss 54 is set to be flush with the front end surface 52 a of the wall portion 52. Since the anti-vibration washer 63 is sandwiched between the grill fixing boss 54 and the lining 22, a gap δ is formed between the lining 22 and the front end surface 52 a of the wall 52 by the thickness of the anti-vibration washer 63. Is done. By having this gap δ, vibration transmission between the lining 22 and the wall 52 can be prevented. In this way, transmission of vibration can be prevented simply by sandwiching the vibration washer 63, which is beneficial.
Note that vibration transmission between the lining 22 and the wall 52 can also be prevented by sandwiching a rubber vibration-proof member between the front end surface 52 a of the wall 52 and the lining 22. . In other words, any configuration can be adopted as long as transmission of vibration from the lining 22 to the wall portion 52 can be prevented. When a rubber vibration isolating member is used, it is possible to prevent dust from entering the speaker grill 50.

Next, an example of a procedure for attaching the speaker 30 and the speaker grill 50 to the existing vehicle 10 will be described.
First, the speaker 30, the speaker grille 50, the plurality of anti-vibration washers 61, the plurality of speaker fixing screws 62, the plurality of anti-vibration washers 63, and the plurality of grill fixing screws 64 are prepared (first step).
Next, the lining 22 where the speaker 30 is attached is temporarily removed from the vehicle body panel 21 (second step).
Next, the speaker hole 26 and a plurality of screw holes 27 are opened in the position where the speaker 30 is attached to the lining 22 (third step).
Next, the speaker 30 is attached to the speaker grille 50 with a plurality of anti-vibration washers 61 and a plurality of speaker fixing screws 62 (fourth step). This fourth step may be performed after the first step.
Next, the speaker grille 50 is attached to the lining 22 with a plurality of anti-vibration washers 63 and a plurality of grill fixing screws 64 (fifth step). As a result, the speaker 30 is attached to the lining 22 via the speaker grill 50.
Finally, the lining 22 is attached to the vehicle body panel 21 (sixth step), thereby completing the attaching operation. Thus, the speaker 30 and the speaker grill 50 are attached to the vehicle 10 via the lining 22.

  In the production process of the vehicle 10, the second step is not necessary when the speaker 30 and the speaker grille 50 are attached. Further, the third step may be performed during the production process of the lining 22.

  Next, a vehicle speaker mounting structure according to Embodiment 2 of the present invention will be described with reference to the drawings. FIG. 5 shows a speaker mounting structure according to the second embodiment, corresponding to FIG.

  In the vehicle speaker mounting structure of the second embodiment, the grill fixing boss 54 and the speaker fixing boss 55 of the speaker grill 50 shown in FIG. 2 are replaced with the grill fixing boss 54A of the speaker grill 50A shown in FIG. The configuration is changed to the speaker fixing boss 55A, and the other configuration is the same as the configuration shown in FIGS.

  Specifically, the grill fixing boss 54A and the speaker fixing boss 55A according to the second embodiment are both formed of an elastic material such as soft resin or rubber, and are integrally formed with the speaker grill 50A. That is, the grill fixing boss 54A and the speaker fixing boss 55A have elasticity.

  The speaker grill 50A is formed by so-called two-color molding in which a hard resin main body 51 and a wall 52 are molded by injection molding, and then a grill fixing boss 54A and a speaker fixing boss 55A made of an elastic material are injection molded. It is formed.

  Since the grill fixing boss 54A is formed of an elastic material, vibration transmitted between the lining 22 and the speaker grill 50A can be suppressed. For this reason, in Example 2, the anti-vibration washer 63 shown in FIG. 2 is unnecessary. The front end surface 54 a of the grill fixing boss 54 A protrudes toward the lining 22 from the front end surface 52 a of the wall portion 52. For this reason, there is a slight gap δ between the lining 22 and the front end surface 52 a of the wall 52. Transmission of vibration between the lining 22 and the wall portion 52 can be prevented.

  In addition, since the speaker fixing boss 55A is formed of an elastic material, vibration transmitted between the speaker grill 50A and the speaker 30 can be suppressed. For this reason, in the second embodiment, the anti-vibration washer 61 shown in FIG. 2 is not necessary.

  According to the second embodiment, the same operations and effects as those of the first embodiment are exhibited. In addition, by forming the grill fixing boss 54A and the speaker fixing boss 55A with an elastic material, vibration transmitted from the road surface to the speaker 30 and the speaker grill 50A via the vehicle body 20 can be weakened. Compared to the case where vibration is suppressed using a separate member, the number of parts can be reduced. Further, since the grill fixing boss 54A and the speaker fixing boss 55A are integrally formed with the speaker grill 50A, the process of attaching the grill fixing boss 54A and the speaker fixing boss 55A to the speaker grill 50A can be omitted. it can. Man-hours can be reduced and manufacturing costs can be reduced.

  Alternatively, after the main body 51 and the wall 52 are injection-molded, separate grill fixing bosses 54A and speaker fixing bosses 55A may be attached to the main body 51. That is, the manufacturing method is not limited to two-color molding, and can be manufactured by any method.

  Next, a vehicle speaker mounting structure according to a third embodiment of the present invention will be described with reference to the drawings. FIG. 6 shows a speaker mounting structure according to the third embodiment, corresponding to FIG.

  In the vehicle speaker mounting structure of the third embodiment, the speaker fixing boss 55 of the speaker grill 50 shown in FIG. 2 also serves as a grill fixing boss as in the speaker grill 50B shown in FIG. The other configuration is substantially the same as the configuration shown in FIGS. 1 to 4 and will not be described. That is, in the vehicle speaker mounting structure of the third embodiment, the grill fixing boss 54 shown in FIG. 2 is omitted.

  Specifically, in the speaker grill 50B of the third embodiment, the front end surface 55a of the speaker fixing boss 55B (boss 55B) is attached to the lining 22 with screws (coupling members) 62B. As described above, the length of the speaker fixing boss 55 is shorter than the length of the grill fixing boss 54 shown in FIG. The portion of the lining 22 that faces the speaker 30 and the speaker fixing boss 55 bulges toward the passenger compartment 12 by an amount substantially corresponding to the difference between the lengths L1 and L2 of the bosses 34 and 35. A bulging portion 22a is formed. The end surface 22b of the bulging portion 22a is formed as a flat surface.

  The flange portion 41 of the speaker 30 is interposed between the tip end surface 55a of the speaker fixing boss 55B and the end surface 22b of the bulging portion 22a, and is coupled by a screw 62. More specifically, the anti-vibration washer 61B, the flange portion 41, the anti-vibration washer 61B, and the tip end surface 55a of the speaker fixing boss 55B are stacked in this order on the end surface 22b of the bulging portion 22a. They are attached together by screws 62.

  Thus, the flange portion 41 (attached portion 41) of the speaker 30 is interposed between the speaker fixing boss 55B (boss 55B) and the lining 22, and the flange portion 41 and the speaker fixing boss 55B are: Both are attached to the lining 22 by the same screw 62B (coupling member 62).

According to the third embodiment, the same operations and effects as those of the first embodiment are exhibited. In addition, the speaker 30 and the speaker grille 50B are attached to the lining 22 with the same screw 62B. By attaching to the lining 22 with the same screw 62B, the speaker 30 and the speaker grille 50B can be attached to the lining 22 with less man-hours.
In particular, when the bulging portion 22a is provided in the lining 22, it is advantageous that the speaker 30 can be attached to a portion with increased rigidity by forming the bulging portion 22a.

  Next, a vehicle speaker mounting structure according to a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 7 shows a speaker mounting structure according to the fourth embodiment, corresponding to FIG.

  The vehicle speaker mounting structure of the fourth embodiment is characterized in that the speaker fixing boss 55B of the speaker grill 50B shown in FIG. 6 is changed to the speaker fixing boss 55C of the speaker grill 50C shown in FIG. The other configuration is the same as the configuration shown in FIG.

  Specifically, the speaker fixing boss 55C according to the fourth embodiment is formed of an elastic material such as soft resin or rubber, and is formed integrally with the speaker grill 50C. That is, the speaker fixing boss 55C has elasticity.

  The speaker grill 50C is formed by so-called two-color molding in which a main body 51 and a wall 52 made of a hard resin are molded by injection molding, and then a speaker fixing boss 55C made of an elastic material is injection molded.

  Since the speaker fixing boss 55C is formed of an elastic material, vibration transmitted between the speaker grill 50C and the speaker 30 can be suppressed. For this reason, in Example 4, the anti-vibration washer 61 interposed between the speaker fixing boss 55C and the flange portion 41 is not necessary.

  According to the fourth embodiment, the same operations and effects as those of the third embodiment are exhibited. In addition, by forming the speaker fixing boss 55C with an elastic material, vibration transmitted from the road surface to the speaker 30 and the speaker grille 50C via the vehicle body 20 can be weakened. Compared to the case where vibration is suppressed using a separate member, the number of parts can be reduced. Furthermore, since the speaker fixing boss 55C is formed integrally with the speaker grill 50C, the step of attaching the speaker fixing boss 55C to the speaker grill 50C can be omitted. Man-hours can be reduced and manufacturing costs can be reduced.

A separate speaker fixing boss 55C may be attached to the main body 51 after the main body 51 and the wall 52 are injection molded. That is, the manufacturing method is not limited to two-color molding, and can be manufactured by any method.
The speaker and the speaker grill according to the present invention have been described by way of example as being attached to the rear luggage compartment of the vehicle, but can also be attached to a ceiling or a vehicle door.
