Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a speaker mounting device.

[Conventional technology]

A conventional speaker mounting device has a structure as shown in FIG.

A speaker mounting hole 3 is provided in the front baffle plate 2 of the speaker box 1, and a plurality of through holes 4 are provided around the speaker mounting hole 3.
It has a structure in which an onymen nut 5 is driven into the through hole 4, and a mounting bolt 7 passing through the speaker frame 6 from the front side is screwed into the onyme nut 5.

Further, in the above structure, a ring-shaped vibration loss material 8 made of a viscoelastic body is inserted between the speaker frame 6 and the front buffle plate 2 for the purpose of absorbing vibrations and improving airtightness.

[Problem that the invention attempts to solve]

In the conventional structure, the mounting structure uses mounting bolts and nuts, so (a) the speaker is fixedly mounted.

(b) Due to the thinness of the speaker mounting part on the front panel and the vibration loss material, the situation is equivalent to that of a loosened mounting bolt.

(c) Therefore, the sound quality is adversely affected.

There were flaws.

The present invention aims to solve these problems.

[Means for solving problems]

The present invention consists of a substantially spherical portion, a flat portion connected to the end of the approximately spherical portion and perpendicular to the axis of the approximately spherical portion, and a flat portion connected to the flat portion and extending in a direction approximately parallel to the axis. A mounting hole is provided around the through hole of the speaker mounting plate, and the mounting piece of the elastic mounting plate is inserted into the mounting hole to attach the elastic mounting plate. It has a structure in which it is attached to the speaker mounting plate, and a mounting bolt that passes through the speaker frame is passed through the through hole and screwed onto the substantially spherical portion of the elastic mounting plate.

According to the problem solving means as described above, the following effects are achieved.

(a) The curved portion of the elastic mounting plate further curves depending on the degree of tightening of the mounting bolt, and the speaker is mounted to the speaker mounting plate with a predetermined elastic force due to the elastic restoring force of the curved portion.

(b) Therefore, the equivalent loosening of the mounting bolt due to thinning of the speaker mounting portion of the speaker mounting plate or the vibration loss material can be absorbed.

(c) Workability is good because the elastic mounting plate can be easily attached to and removed from the speaker mounting plate.

〔Example〕

This will be explained with reference to FIGS. 1 and 2. In the figure,
Components equivalent to those of the conventional example shown in FIG. 3 are given the same reference numerals, and their explanations will be omitted.

Reference numeral 9 denotes a substantially cross-shaped elastic mounting plate, which includes a substantially cross-shaped substantially spherical portion 9a with a screw hole 10 provided in the center, and is integrally connected to an end of this substantially spherical portion 9a. A flat part 9b perpendicular to the axis of the part, a mounting piece 9c integrally connected to the flat part 9b and extending in a direction substantially perpendicular to the axis, and integrally connected to the end of the mounting piece 9c. It consists of a large locking part 9d.

On the other hand, around the through hole 4 of the front baffle plate 2,
A mounting hole 11 is provided at a position corresponding to the mounting piece 9c of the elastic mounting plate 9, and a notch 12 is provided by cutting the front opening edge of this mounting hole 11.

Then, the mounting piece 9c of the elastic mounting plate 9 is inserted into the mounting hole 11, the enlarged locking part 9d is locked in the notch 12, and the elastic mounting plate 9 is inserted into the substantially spherical part 9a of the elastic mounting plate 9 through the through hole. 4 facing the front buttful plate 2
Attach to.

Here, since the large locking portion 9d is inserted into the mounting hole 11, there is a slight gap between the wall surface of the mounting hole 11 and the mounting piece 9c.

Mounting bolt 7 passing through speaker frame 6
through the through hole 4 of the front face full plate 2,
Screw into the screw hole 10 of the elastic mounting plate 9 and tighten. The substantially spherical portion 9a of the elastic mounting plate 9 expands depending on the degree of tightening of the mounting bolt 7. Due to the elastic restoring force of the substantially spherical portion 9a, the speaker is attached to the front baffle plate 2 by being elastically pressed against it.

In the above embodiment, the elastic mounting plate 9 may have a Y-shape, star-shape, or other shape, and the speaker may have the same or similar shape not only on the front bumper plate 2 but also on the side surface of the speaker box. Can be installed depending on the structure.

[Effect of idea]

According to the present invention as described above, (a) the speaker can be attached with a predetermined elastic force;

(b) Equivalent loosening of the mounting bolts due to thinning of the speaker mounting portion of the speaker mounting plate or the vibration loss material can be absorbed.

(c) There is no deterioration in sound quality due to equivalent loosening of the mounting bolts.

(d) Workability is good because the elastic mounting plate can be easily attached to and removed from the speaker mounting plate.
