Description of the Related Art In recent years, in the field of electronic devices with built-in speakers, such as display devices for personal computers, speakers have been built in display devices of computer devices in addition to television receivers and audio devices. ing. For this reason, it is desired to minimize the influence of the vibration generated from the speaker on other electronic devices.

[0003]

As a conventional speaker mounting structure of this type, a bushing material such as a rubber member is mounted on a mounting flange portion of the speaker, and an electronic device housing is mounted via the bushing material. It was a method of screw fixing to the part. However, the elasticity of the bushing material is affected by the tightening force of the screw.
If the tightening force of the screw is high, the bushing material is strongly compressed, and the inherent elasticity of the rubber is lost, and it is difficult to obtain the effect of suppressing the vibration generated from the speaker from being transmitted to other electronic devices.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and a speaker mounting mechanism capable of effectively suppressing transmission of vibration from a speaker to other electronic devices. The purpose is to obtain.

[0005]

In order to achieve the above-mentioned object, a speaker mounting mechanism according to the present invention comprises a holder in which a vibration absorbing member is inserted into a mounting flange of a speaker unit, and an integral part of the holder. The speaker unit is formed with a mounting portion fixed to the housing of the electronic device, and the mounting portion is screwed to the housing of the electronic device while the mounting flange portion is held by the holder portion.

With this configuration, the vibration generated from the speaker is transmitted to the mounting flange. However, since the mounting flange is inserted into the holder of the vibration absorbing member, the vibration generated in the mounting flange is generated. Almost all of them are absorbed in the holder portion and are not transmitted to the mounting portion. Therefore, vibration to the electronic device housing can be avoided.

Further, the vibration absorbing member is made of an elastomer or an elastic rubber material having a high elastic coefficient. Thereby, the function of absorbing vibration can be enhanced.

The holder has a bag shape in which the mounting flange is accommodated. Thereby, the entire surface of the mounting flange portion of the speaker can be brought into surface contact with the inner surface of the holder portion, whereby the vibration transmitted to the holder portion is dispersed,
The effect of absorbing vibration can be enhanced.

The bag-shaped inner surface of the holder is formed as a fold surface. This effectively absorbs the vibration transmitted from the mounting flange of the speaker to the holder by the folds,
The vibration absorbing function of the entire holder can be further enhanced.

Further, the mounting portion has a through-hole which is erected from the housing of the electronic device and is inserted into a mounting boss having a thread groove on the inner surface, and this through-hole is formed as a fold surface. Thus, even if a part of the vibration is transmitted from the holder to the mounting part, the vibration is finally absorbed by the folds and does not exert a vibration on the boss of the electronic device housing.
