For example, the video-audio device 5 rotates the rotary shaft 6 by the motor 7, and controls the rotation of the video-sound device 5 by the motor 7 by the controller 8. By controlling it, it is possible to rotate back and forth on the basis of the wall (3), the specific example can be referred to the above-mentioned Republic of Korea Patent No. 10-064883.

In the case of the rotatable image-acoustic device system 2 of FIG. 1, the rotating image-acoustic device 5 and the through hole 4 are formed over the entire height of the wall 3, but the through hole ( It is obvious that the sound insulation device 1 of the present invention can be applied to a system in which 4) is not formed over the entire height of the wall 3 but is formed over a certain height and width so that the image-acoustic device 5 rotates. Do.

Soundproofing device 1 according to the invention, basically, the wall frame 10, the sound insulation groove 11, the device frame 20, sound insulation entrance and exit piece 30, the connecting rod 40, the elastic member 50, Cam 60 and drive motor 70 is included.

The wall frame 10 is a frame installed around the inner circumference of the through hole 4 formed in the wall 3 to form a space in which the image-acoustic device 5 can be rotatably mounted.

The sound insulating groove 11 is formed in the wall frame 10, for example, on the contact surface 10a facing the device frame 20 of the image-acoustic device 5 inserted into the wall frame 10. It is formed into a mold.

As shown in Fig. 4, forming the contact surfaces 10a and 20a of the wall frame 10 and the device frame 20 into circular arcs having the same center is characterized in that the contact surfaces 10a and 20a correspond to the image-acoustic apparatus ( This is to avoid obstacles to the rotation of 5).

The apparatus frame 20 is a frame installed around the image-acoustic apparatus 5 and faces the wall frame 10, and the image-acoustic apparatus 5 is mounted in the apparatus frame 20. It rotates within the frame 10.

The sound entry and exit piece 30 is formed on the contact surface (20a) of the device frame 20 in contact with the wall frame 10, it is installed in the mounting hole 21 formed in a position corresponding to the sound insulation groove (11). The sound insulation entrance and exit piece 30 is not formed as a single member over the entire side of the apparatus frame 20, but is divided into at least one side unit so as to enter and exit from each side in a different direction.

The sound insulating entrance and exit piece 30 is installed to fit in and out of the sound insulating recess 11 of the wall frame 10, and cooperates with the sound insulating recess 11 of the wall frame 10 to perform sound insulation.

That is, when the sound insulation entrance and exit piece 30 is inserted into the sound insulation recess 11 while the wall frame 10 and the device frame 20 are in contact with the contact surfaces 10a and 20a, the wall frame 10 and the device frame ( 20, the sound passing through the gap between the block and the sound entry and exit piece 30 is separated from the sound insulating recess 11, the device frame 20 can be rotated with respect to the wall frame 10, the image-acoustic The device 5 is in a rotatable state.
