The requirements of emerging application scenarios place new demands on the design of sound insulation rooms. On one hand, in the prior fixed sound insulation room, the sound insulation measure of the room is to add a structure with a sound insulation function on the wall surface, and the mode needs a fixed wall body as a support on one hand and increases the thickness of the wall body on the other hand; if the wall body with the sound absorption function is designed independently, the use safety is possibly influenced due to the bearing problem; on the other hand, the traditional sound insulation room does not simulate the environmental sound effect, and the requirement of virtual scenes possibly under various application scenes is not met.
If the sound insulation room is designed to be independent without depending on the existing wall body, the following technical characteristics need to be included: 1) the weight of the sound-proof compartment needs to be controlled to facilitate movement; 2) the thickness of the sound-proof room needs to be controlled to improve the space utilization rate; the above technical requirements will inevitably cause a contradiction between the sound insulation quality control and the weight and volume control of the sound insulation room. In addition, the emerging sound-proof room needs to be added with a multimedia screen to improve interactivity and commerciality, which also increases the overall thickness of the sound-proof room and requires a higher sound-absorbing effect. Therefore, it is necessary to provide a lightweight independent sound insulation room, which can reduce the volume of a wall body and improve the sound absorption effect while ensuring the strength of the sound insulation room, and in addition, the live broadcast or conference background can be switched freely in the sound insulation room.

And further, the hollow sound-insulating glass comprises light-transmitting glass, wherein the side surface or the top surface is arranged between the keel frame bodies, the sound-absorbing plate arranged at the position is eliminated, and the hollow sound-insulating glass is changed into the hollow sound-insulating glass for transmitting light.
Further, the air exhaust mechanism can be an exhaust fan or an air conditioner and is arranged between the skeleton bodies, the installation of the acoustic boards at the position is cancelled, or only the local area is installed, and the residual area is used for installing an air exchange opening of the air exhaust mechanism.
Furthermore, the first multimedia screen and the second multimedia screen are connected with a terminal control, and the terminal control is a computer and can switch the content played by the screens. Generally, the first multimedia screen can be used as a commercial, advertisement or propaganda information; the second multimedia screen may be used for background scene switching or simulation. Preferably, the frame rate of the second multimedia screen is higher than that of the first multimedia screen, the high frame rate screen is beneficial to displaying more vivid and lifelike pictures on the inner surface layer, the requirement of environment simulation is met, and different contents can be displayed on each media screen through the terminal so as to meet different application scenes. In the in-service use process, can be according to the demand of the different application scenes between giving sound insulation, install required equipment in giving sound insulation, including drinking water equipment, seat, office computer, microphone, stereo set etc..
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
