Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting device with a speaker for supporting an electronic device such as a television receiver for reproducing an image and reproducing a sound by incorporating a speaker portion forming a part of the electronic device.

[0002]

2. Description of the Related Art Electronic equipment for reproducing images and sounds,
For example, in a supporting device for supporting a television receiver, a television receiver and a main body portion including an image display portion in the television receiver meet the requirements from the viewpoint of acoustic effects or design requirements. The speaker unit that constitutes a part of the above is practically used by being separated from each other and supported. Such a support device, for example, a support base that supports the main body of the television receiver,
It consists of a base that is supposed to have a built-in speaker section of the television receiver, and a support stand that supports the main body is attached to the upper part of the base that has the built-in speaker section and both are integrated. It Further, a display on an image display screen portion provided in an image display unit included in the main body is provided as a supporting device that separates the main body and the speaker of the television receiver from each other and supports them by a support base and a base, respectively. It is known that a support base attached to an upper part of a base having a built-in speaker unit is rotatable with respect to the base so that the front direction can be easily changed. .

[0003]

However, as described above, the support base for supporting the main body of the television receiver is attached to the upper part of the base having the speaker portion of the television receiver built thereinto. In the support device integrated with the support base, the vibration generated when the speaker unit operates is transmitted from the base base to the support base, and further transmitted from the support base to the image display unit included in the main body. As a result, there is a problem that "shaking" in the image reproduced on the image display screen portion provided in the image display unit, that is, partial or total small round-trip fluctuations occur. The problem of "shaking" in the reproduced image caused by the vibration generated when the speaker unit operates is
When the support base that supports the main body of the television receiver is attached to the upper part of the base that contains the speaker,
There is a possibility that it may become particularly serious in the case of being rotatable with respect to the base.

In the past, some measures against such a problem have been proposed, but with a relatively simple structure, an image display section is provided by a support table arranged on a base table containing a speaker section. The supporting device is capable of securely supporting the main body part that is provided, and surely preventing "shaking" in the reproduced image obtained by the image display part, which is caused by the vibration that occurs when the speaker part operates. I can't find it.

In view of the above point, the present invention is relatively simple and reduces the cost in supporting an electronic device for image reproduction and audio reproduction by separating the main body part including the image display part and the speaker part from each other. In addition to supporting the speaker unit as a built-in base,
The main body portion including the image display portion can be reliably supported by the support table arranged on the base, and further, in the reproduced image obtained by the image display portion due to the vibration generated during the operation of the speaker portion. It is an object of the present invention to provide a supporting device with a speaker, which can effectively prevent "sway".

[0006]

In order to achieve the above object, a supporting device with a speaker according to the present invention includes an image display unit in an electronic device such as a television receiver for performing image reproduction and sound reproduction. A support for supporting the main body,
It is arranged below the support base and is connected to the upper part of the base that houses the speaker portion of the electronic device by a vibration-proof connection member having elasticity.

[0007]

In the speaker supporting device according to the present invention having the above-described structure, the support base for supporting the main body portion including the image display portion of the electronic device has the speaker portion of the electronic device built therein. Is connected to the base via a vibration-proof connecting member, and is arranged on the base. As a result, the main body section including the image display section and the speaker section are securely supported under a relatively simple and cost-reducing configuration, and vibration transmission from the base to the support is performed by the vibration-proof connecting member. As a result, "shaking" in the reproduced image obtained by the image display unit due to the vibration generated when the speaker unit operates is effectively prevented.
