Since the display monitor body 1 incorporating the acoustic output device as shown in FIG. 6 has the structure in which the speaker 3 and the amplifier circuit 4 are incorporated, the acoustic output device is already incorporated. It is impossible for a user who owns a display monitor main body which does not have a sound output device to be integrated with the display monitor main body as needed. Further, since the built-in speaker 3 is close to the CRT (CRT) of the display monitor main body 1, the vibration of the speaker 3 is a CRT.
There is also a problem that it is transmitted to the inner shadow mask and induces screen shake.

On the other hand, from the standpoint of the producer, in order to add the conventional model with the built-in sound output device, a space for accommodating the amplifier circuit 4 and the speaker 3 in the display monitor body is secured, Further, since it is necessary to modify the mold and the like, the cost and time required for the development become enormous, and it is difficult to add a new model by a small modification of the conventional model.

When the speakers 9 and 11 and the amplifier 8 are externally provided as an audio output device of a computer system, it is necessary to secure a space for installation, a sense of inconsistency in design, a cable 10, There is a problem that the number of 12 increases and the connection work becomes complicated.

The present invention solves the above-mentioned problems, and does not require modification of the display monitor body or increase of installation space, and an acoustic output device built-in rotation that can be easily added to a computer system. The purpose is to provide a stand.

[0013]

In order to solve the above-mentioned problems, the present invention provides an amplifier and a speaker for reproducing an audio signal from an audio signal output device such as a computer on a turntable supporting a display monitor body. It has a built-in.

[0014]

According to the above-mentioned structure of the present invention, the user mounts the rotary table with the built-in sound output device as necessary, so that the display monitor main body is not changed and the amplifier and the amplifier built in the rotary table are not changed. The speaker can be easily added to an existing computer system without increasing the installation space.

Further, since the vibration of the speaker built in the turntable is attenuated at the contact portion between the turntable built in the acoustic output device and the display monitor body, it is possible to prevent the screen shake from being induced by the vibration. .

On the other hand, for a producer, if a common rotating base is developed for each existing display monitor, the sound output device can be added to each display monitor main body without any modification. Compared to the case of developing a display monitor with a built-in display, the cost and time required for development can be reduced, and new demand can be expected due to optional sales of the rotary table with built-in sound output device.
