  According to the mounting structure of the speaker according to the conventional example described above, the speaker body can be securely fixed to a desired site by using the bracket, but the speaker support section provided on the installation member and the bracket mounting section Therefore, it is difficult to apply to a vehicle-mounted speaker that is highly likely to have different positions for forming the speaker support portion depending on the vehicle type. In particular, when a user replaces a genuine product with a desired speaker body, the size and shape of the new speaker body to be replaced are often different from those of the genuine product, so there are many types depending on the vehicle model to which the genuine product was attached. Brackets had to be prepared, which was uneconomical and costly. Further, when the bracket is changed with the replacement of the speaker main body, there is a possibility that the speaker main body and the bracket cannot be incorporated into a limited space in the opening.

  The present invention has been made in view of the actual situation of the prior art, and an object thereof is to provide an in-vehicle speaker mounting structure capable of easily and reliably mounting a speaker body on the back surface of various shapes of mounting panels. There is to do.

  The present invention uses a bottomed cushion member as a support means of the speaker body, and in the state where the speaker body is inserted and held in the storage part of the cushion member, an attachment surface located around the opening end of the storage part is provided. It was fixed to the back of the mounting panel installed in the passenger compartment.

The mounting structure of the vehicle-mounted speaker according to the present invention is such that the mounting surface positioned around the opening end of the storage portion is a mounting panel in a state where the speaker body is held inside the storage portion formed in the bottomed cushion member. Since the mounting surface of the cushion member is deformed following the shape of the mounting panel, the speaker body can be easily and securely mounted on the back surface of various types of mounting panels. it can. In addition, the foam cushion member that surrounds the speaker body having a structure for releasing the back pressure of the diaphragm from the through-hole provided in the yoke exhibits the same sound absorption effect as the back cavity, thereby defining the back cavity. It is possible to provide an in-vehicle speaker mounting structure that can be installed in a space where there is no room.

The mounting structure of the vehicle-mounted speaker according to the present invention, a cushioning member having a bottom shape composed of foam around the open end and the mounting surface of the housing portion and having an accommodating portion having an open end, the magnet inside the yoke And a voice coil, and a speaker main body configured to relieve the back pressure of the diaphragm from the through hole provided in the yoke, and the speaker main body with the through hole facing the inner surface of the storage portion. It is held in the housing unit and so as to adhesively fixed to the rear surface of the mounting panel to the mounting surface is disposed in the passenger compartment of the cushion member.

In the mounting structure of the vehicle-mounted speaker configured as described above, the mounting located around the opening end of the storage portion in a state where the speaker body is held inside the storage portion formed in the bottomed cushion member. Since the surface is adhesively fixed to the back surface of the mounting panel, the mounting surface of the cushion member deforms following the shape of the mounting panel, so that the speaker body can be easily and securely attached to the back surface of the mounting panel of various shapes. Can be attached to. In addition, the foam cushion member that surrounds the speaker body having a structure for releasing the back pressure of the diaphragm from the through-hole provided in the yoke exhibits the same sound absorption effect as the back cavity, thereby defining the back cavity. It is possible to provide an in-vehicle speaker mounting structure that can be installed in a space where there is no room.

  In the above configuration, when the upper end of the speaker body is immersed in the storage portion with respect to the mounting surface of the cushion member, a large gap is formed between the upper end of the speaker body held in the storage portion and the back surface of the mounting panel. Therefore, when the mounting surface of the cushion member is bonded and fixed to the back surface of the mounting panel, it is preferable that the mounting surface as the bonding site can be pressed against the back surface of the mounting panel without being obstructed by the speaker body.

  In addition, in the above configuration, when the protrusion provided on the outer peripheral surface of the speaker body is locked to the inner peripheral surface of the storage portion of the cushion member, the protrusion is caught during the operation of bonding and fixing the cushion member to the back surface of the mounting panel. This prevents the speaker body from inadvertently dropping from the storage portion, which is preferable because the cushion member can be easily bonded and fixed to the mounting panel.

  The embodiment will be described with reference to the drawings. FIG. 1 is a sectional view showing a mounting structure of a vehicle-mounted speaker according to a first embodiment of the present invention, and FIG. 2 shows a speaker body and a cushion member before being attached to a mounting panel. FIG. 3 is an explanatory view showing a speaker body and a cushion member in the middle of being attached to the attachment panel.

  A speaker main body 1 shown in FIGS. 1 to 3 is a tweeter used for high sounds of an in-vehicle audio system, and has a bottomed cushion member on the back surface of a mounting panel 2 disposed at an appropriate position in a vehicle interior. 3 is attached. The speaker body 1 incorporates known speaker components such as a yoke 4, a magnet 5, a voice coil 6, and a diaphragm 7, and a frame 8 having a protrusion 8 a on the outer peripheral surface is integrated with the upper end of the yoke 4. It has become. A plurality of through holes 4a are formed in the bottom surface of the yoke 4, and the back pressure of the diaphragm 7 is released from these through holes 4a.

  The mounting panel 2 can be attached to and detached from an opening (not shown) provided in a door panel, an A pillar, or the like, and a dustproof net 2a that transmits sound output from the speaker body 1 is attached.

  The cushion member 3 is made of a foam having a high elasticity such as polyethylene or polyurethane, and a cylindrical storage portion 3a having an open upper end is formed at the center thereof. The upper end surface of the cushion member 3 is an attachment surface 3b that is bonded to the attachment panel 2. The attachment surface 3b is formed in an annular shape so as to surround the opening end of the storage portion 3a. The speaker body 1 is inserted and held inside the storage portion 3a and is not shown in the figure. However, a hole for leading a wire connected to the voice coil 6 of the speaker body 1 is provided around the storage portion 3a. Is formed. The depth of the storage portion 3a is set to be larger than the height of the speaker main body 1, and the speaker main body 1 has an upper end of the storage portion 3a with respect to the mounting surface 3b (open end of the storage portion 3a). It is held inside. Further, the diameter of the storage portion 3a is set to be slightly smaller than the outer diameter of the speaker body 1, and the projection 8a of the frame 8 bites into the inner peripheral surface of the storage portion 3a and gets caught when the speaker body 1 is inserted. The speaker body 1 is prevented from inadvertently dropping from the storage portion 3a.

  Next, the attachment method of the speaker main body 1 in a present Example is demonstrated. First, as shown in FIG. 2, a cushion member 3 is prepared in which one side of a double-sided adhesive tape 9 is attached to the mounting surface 3b, and an operator inserts the speaker main body 1 into the storage portion 3a from above the cushion member 3. Thus, as shown in FIG. 3, the speaker body 1 is held on the cushion member 3 in a state of being placed on the inner bottom surface of the storage portion 3a. As described above, when the speaker body 1 is inserted, the protrusion 8a bites into and catches on the inner peripheral surface of the storage portion 3a and prevents the speaker body 1 from being inadvertently detached from the storage portion 3a. The cushion member 3 can be easily handled without worrying about the dropping off of the main body 1.

Thereafter, the speaker body 1 is opposed to the dust-proof net 2a from the back surface side of the mounting panel 2, and the mounting surface 3b of the cushion member 3 is pressed against the back surface of the mounting panel 2 in this state, and the other surface of the double-sided adhesive tape 9 is adhered. By doing so, as shown in FIG. 1, the mounting surface 3 b of the cushion member 3 is bonded and fixed to the back surface of the mounting panel 2 via the double-sided adhesive tape 9. At this time, the upper end of the speaker main body 1 is held in a state where it is submerged inside the storage portion 3a with respect to the mounting surface 3b, and even when the mounting surface 3b is abutted against the mounting panel 2, it is attached to the upper end of the speaker main body 1. since a large gap is secured between the back surface of the panel 2, the operator can be adhered and fixed only with press mounting surface 3b without being disturbed by the speaker body 1 to the rear surface of the mounting panel 2. In this state, the speaker main body 1 and the cushion member 3 are assembled in a space facing an opening (not shown), and the mounting panel 2 is fixed to the opening using screws, snaps, or the like. The speaker main body 1 can be placed in an immersive state in a space facing an opening provided in, for example.

  In the embodiment described above, the speaker main body 1 is held inside the storage portion 3 a formed in the bottomed cushion member 3, and the mounting surface 3 b of the cushion member 3 is held via the double-sided adhesive tape 9 in this state. Since the attachment surface 3b of the cushion member 3 having excellent elasticity is freely deformed following the shape of the back surface of the mounting panel 2, the speaker body 1 can be easily attached to the various shapes of the mounting panel 2 because the attachment surface 3b is bonded and fixed to the back surface of the mounting panel 2. And it can be securely attached. In addition, since the upper end of the speaker body 1 is held in the cushion member 3 in a state where the upper end of the speaker body 1 is not protruded from the mounting surface 3b and is immersed in the storage portion 3a, the mounting panel 2 is attached when the cushion member 3 is bonded and fixed to the mounting panel 2. It is possible to easily press the attachment surface 3b, which is an adhesion portion, to the back surface of the attachment panel 2 without being obstructed by the speaker body 1. Further, since the protrusion 8a provided on the outer peripheral surface of the speaker body 1 is locked to the inner peripheral surface of the storage portion 3a of the cushion member 3, the speaker member 3 is bonded to the mounting panel 2 during the work of fixing the speaker. It is possible to prevent the main body 1 from being accidentally dropped from the storage portion 3a.

  Further, in the above-described embodiment, the speaker body 1 having a structure in which the back pressure of the diaphragm 7 is released from the through hole 4a formed in the bottom surface of the yoke 4 is used. However, since the cushion member 3 that surrounds the speaker body 1 exhibits the same sound absorbing effect as the back cavity, it can be used even in a space where there is no room to define the back cavity in space. The speaker body 1 and the cushion member 3 can be incorporated.

  FIG. 4 is a cross-sectional view showing a mounting structure of a vehicle-mounted speaker according to a second embodiment of the present invention, FIG. 5 is an explanatory view showing a speaker body and a cushion member before being attached to the mounting panel, and FIG. It is explanatory drawing which shows the speaker main body and cushion member of this, and duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol to the part corresponding to FIGS.

  This embodiment is different from the first embodiment described above in that the bottomed cushion member 3 is configured by integrating the flat plate portion 3A and the ring portion 3B that are separately formed. The configuration is basically the same. The flat plate portion 3A is formed in a disc shape, and by adhering and fixing the lower end surface of the ring portion 3B to the outer peripheral portion of the flat plate portion 3A, a cylindrical storage portion 3a having an open upper end is formed. The upper end surface of the ring portion 3 </ b> B becomes a mounting surface 3 b bonded to the mounting panel 2. Here, the flat plate portion 3A and the ring portion 3B may be integrated in advance before the speaker body 1 is held, but as shown in FIG. 5, the speaker is separated using the flat plate portion 3A and the ring portion 3B in the separated state. When the main body 1 is held, the wire (not shown) of the speaker main body 1 can be easily pulled out from between the bonding surfaces of the flat plate portion 3A and the ring portion 3B.
