Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a structure for mounting a speaker to a cabinet, a speaker, or the like.

[Prior art] Conventional structures for attaching a speaker to a cabinet or bracket include a structure in which the speaker is attached and fixed using screws, bolts, etc., a structure in which the speaker is bonded and fixed using an adhesive, and a structure in which the speaker is attached and fixed using an adhesive, and a structure in which the speaker is attached by heat fusion using a pin installed integrally in a synthetic resin cabinet. Fixing structures and mounting and fixing structures using claw metal fittings were often used, but in recent years, as a structure for attaching speakers without using the above-mentioned fixing metal fittings, for example, as shown in Fig. 3, a structure with a cross section of approximately L formed integrally on the inner surface of the cabinet 01 has been proposed. The speaker 02 is attached to the cabinet 01 by fitting the outer circumference of the speaker 02 into the grooves 01c and 01d formed by the letter-shaped angles 01a and 01b.
A structure was devised to attach and fix the .

[Problems to be solved by the invention] In the mounting structure having the above configuration, as shown in FIG. 4, the thickness A of the outer peripheral part of the speaker 02 is
The width a of the grooves 01c and 01d is required to be slightly larger than the width a of the grooves 01c and 01d of the cabinet 01, but since the cabinet 01 itself is made of synthetic resin, it is susceptible to variations due to deformation during molding, thermal deformation due to the temperature of the usage atmosphere, etc. It was difficult to strictly maintain the above conditions due to dimensional errors in the gasket 02c of the speaker 02.

Also, as in Japanese Utility Model Publication No. 10217/1983, by forming a cut and raised piece on the flat part of the speaker frame and inserting the tip of the cut and raised piece into the inner surface of the groove formed by the angle having a substantially L-shaped cross section. There is a mounting structure in which the speaker is mounted and fixed, and the dimensional error is absorbed by the elasticity of the cut and raised pieces.

However, in this structure, the mounting direction of the speaker is specified, so even if the speaker has the same shape, the shape of the cabinet to which it should be mounted,
In particular, this method cannot be adopted if the driving power supply lines are drawn out in different directions, and there is a drawback that it is necessary to prepare various speakers of the same shape with different formation positions of the cut and raised pieces.

[Means for Solving the Problems] This invention consists of a cabinet having an approximately L-shaped cross-sectional angle formed in parallel on the inner surface, and an approximately rectangular outer periphery, each of which is bent at each of the four corners to form a bent piece. This speaker mounting structure includes a speaker having a formed frame, and the speaker is attached by fitting the bent piece forming portion of the speaker into a groove formed between the angle having a substantially L-shaped cross section and the cabinet.

[Embodiment] This invention will be described with reference to an embodiment shown in FIG.
a, 1b are integrally formed in parallel, grooves 1c, 1d are formed between the cabinet 1 and the angles 1a, 1b, respectively, and a sound emitting hole 1e is bored in the cabinet 1. .

Reference numeral 2 denotes a speaker having a frame 2a having a substantially rectangular outer peripheral edge, and each corner of the frame 2a is bent into a substantially doglegged shape to form a bent piece 2b.

As shown in FIG. 2, the dimension A from the bottom surface of the outer periphery of the frame 2a to the front surface of the gasket 2c is the distance between the cabinet 1 and the L-shaped angles 1a and 1b.
The dimension B from the lowest part of the bent piece 2b to the front surface of the gasket 2c is larger than the width a of the grooves 1c and 1d.

According to the above configuration, the frame 2a of the speaker 2
The speaker 2 is elastically supported within the grooves 1c, 1d by the elastic restoring force of the bent piece 2b, and is attached and fixed to the cabinet 1 only by fitting the outer peripheral portion into the grooves 1c, 1d.

[Effects of the invention] According to the invention explained in the above embodiment, (1) Since the elastic force of the bent piece is used for fixation, some error occurs between the width of the groove and the dimension A. Even if the width of the groove changes due to fluctuations due to deformation during molding or thermal deformation due to the temperature of the usage atmosphere, or even if the tolerance of the width of the groove is made large, it can be absorbed by the amount of displacement of the bent piece. Even if the tolerance of the dimension A of the outer periphery of the speaker frame including the gasket is increased, it is possible to mount and fix the speaker in a predetermined manner.

(2) Since the bent pieces are provided at each of the four corners of the speaker frame, it can be installed in any of the four directions of the speaker frame.If the positional relationship of the angles is the same, For example, the same speaker can be used even if the drive power supply lines are drawn out in different directions, and costs can be reduced by mass production of the same structure.

Note that the shape of the bent piece is not limited to a dogleg shape, and the same effect can be obtained even if it is, for example, a U shape.
