Description

[Detailed Description of the Invention] The present invention relates to a speaker mounting device for mounting a speaker to a cabinet such as a radio receiver.

2. Description of the Related Art Conventionally, a method shown in FIG. 1 has been known as a method for attaching a speaker to, for example, a radio receiver cabinet.

First, to briefly explain this, the main body of the cabinet is composed of a separable assembly of a front cabinet auxiliary body 1 and a rear cabinet auxiliary body 2, which are combined to form a cabinet. A speaker 3 is installed in the through hole or opening (not shown) in advance.
The sound emitting part of is temporarily fixed.

On the other hand, a support base 4 is provided protruding from the rear cabinet auxiliary body 2, and a cushion material 5 such as a sponge is attached to the support base 4 by a method such as adhesive bonding.

By abutting and coupling the cabinet auxiliary bodies 1 and 2 to which the speaker 3 and the cushioning material 5 are respectively attached, the overwriting force 3 is elastically and firmly fixed within the cabinet body. It's becoming like that.

However, the work of temporarily fixing or gluing the speaker 3 and cushioning material 5 to the two cabinet auxiliary bodies 1 and 2 is complicated in the radio assembly work, and the number of steps increases accordingly, resulting in poor workability and making automatic assembly difficult. There were some drawbacks such as:

On the other hand, the speaker 3 is adhered or placed on the cushion material 5, and finally the speaker 3 is placed in the opening of the speaker 3.
Front cabinet auxiliary body 1 so as to match the above-mentioned through holes etc.
A method was also adopted in which the speaker 3 was connected to the rear cabinet auxiliary body 2, but in this case, the speaker 3 was not temporarily fixed, so the work of bringing the opening of the speaker 3 into contact with the predetermined part of the front cabinet auxiliary body 1 was carried out. There were drawbacks such as difficulty.

FIG. 2 shows another conventional example.

The cabinet body is composed of a separable assembly of a front cabinet auxiliary body 6 and a rear cabinet auxiliary body T, and a speaker is installed in a through hole or opening (not shown) in the front cabinet auxiliary body 6. No. 8 sound emitting section is temporarily fixed.

On the other hand, a boss 9 is integrally provided on the inner side of the rear cabinet auxiliary body 1, and a coil spring 11 is accommodated in a recess 10 of the boss 9.

By abutting and coupling the two cabinet auxiliary bodies 6 and 7, the protrusion 12 that encloses the magnetic circuit of the speaker 8 fits into the recess 10, and the protrusion 12 engages with the spring 11. It is resiliently supported so that the speaker 8 is firmly fixed within the cabinet body.

However, with such a configuration, a relatively expensive coil spring 11 is required;
The spring force of 1 tends to vary, which tends to make assembly work complicated.

The present invention was made to improve such conventional drawbacks, and combines a magnetic circuit storage section in which the magnetic circuit of a speaker is stored, and a pair of cabinet auxiliary bodies provided at the proximal end of this storage section. A relative fitting part is integrally formed with a synthetic resin on an engaging protrusion provided on one cabinet auxiliary body of a cabinet constituted by a cabinet, and a plurality of elastic pieces provided on the tip side of the magnetic circuit housing part. a holding member, the magnetic circuit of the speaker is housed in the magnetic circuit storage portion of the holding member to hold the speaker, and the fitting portion is fitted to the engaging protrusion of one of the cabinet auxiliary bodies; By combining one cabinet auxiliary body with the other cabinet auxiliary body, the speaker frame is elastically suppressed and supported by a plurality of elastic pieces provided on the cabinet and the holding member, and the speaker is mounted in the cabinet. Accordingly, it is an object of the present invention to provide a novel speaker mounting device that allows the speaker to be mounted to a cabinet easily and reliably.

An embodiment of the present invention will be specifically described below with reference to the drawings.
