Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel speaker fixing structure. More specifically, it is an object of the present invention to provide a novel speaker fixing structure in which speaker mounting is simple and vibration of the speaker is suppressed to prevent so-called flicker of sound.

[0002]

2. Description of the Related Art Conventional speaker fixing, for example,
To fix the speaker in the television receiver, a large number of sound emission holes are formed on the side surface of the front frame called a bezel of the housing, and the speaker is directly screwed inside the portion where the sound emission holes are formed. It was fixed.

[0003]

Therefore, in the above-described conventional speaker fixing structure, it is necessary to tighten several screws, which is troublesome, and when the speaker is replaced, the above screws must be attached. There is a problem that a driver is needed to loosen it and it takes time.

Further, since the front frame is directly screw-fastened, when the volume is increased, the front cover and the rear cover attached so as to cover the rear part of the frame often vibrate, and so-called flicker of sound is often generated. As a measure against such sound flicker, there is a problem that extra members and extra labor are required, such as a member for absorbing vibration such as non-woven fabric must be interposed between the speaker and the front frame.

[0005]

In order to solve the above-mentioned problems, the speaker fixing structure of the present invention includes a contact surface for contacting a front surface of the speaker with a support member made of synthetic resin and a part of the speaker. A holding portion for engaging and holding and a resilient portion for resiliently contacting the contact surface with the speaker held by the holding portion are formed.

[0006]

Therefore, in the speaker fixing structure of the present invention, the front surface of the speaker is brought into contact with the contact surface of the support member,
Since the speaker can be attached to the support member only by elastically contacting the speaker with the contact surface by the elastic unit,
The workability of attachment and detachment is good, and since the elastic part absorbs the vibration of the speaker, so-called flicker of sound can be suppressed.
