Description

Sound sensory device {SOUND BODILY SENSED SYSTEM}

The present invention relates to an acoustic sensation system (Sound Bodily Sensed System) to convert the electrical sound signal output from various sound equipment, such as mechanical vibration to the human body.

The acoustic sensor may convert an electric sound signal into a powerful vibration to transmit a low level vibration deeply to a human body, and maximize the effect when listening like a surround sound or a stereo sound.

In addition, the sound sensor may be applied to various AV systems such as music, movies, and games, such as a sofa for watching DVD (or video), a PC room vibration chair, a karaoke sofa, and a music listening vibration chair. When mounted on a chair or a floor, it can produce a three-dimensional appreciation effect by listening to sound and vibrating.

For example, the publication of Korean Patent Application No. 1991-181 exemplifies such an acoustic sensor. In particular, the publication described in Figure 2 is a vibrating body is installed inside the casing consisting of a top cover, a circular hole in the center, a stopper and a bottom cover for blocking the circular hole, the vibrating body in the center of the disc It is composed of a fixed coupling of the central body, the magnet, the support ring and the elastic damper is raised.

However, since the acoustic winder disclosed in the above publication has a structure in which the upper and lower covers are completely enclosed, there is not enough space between the upper and lower covers, so that heat generated by vibration of the damper cannot be released to the outside. As a result, load rise and current consumption increase.

In addition, there is a problem in that the center of gravity of the protrusion including the diaphragm, the magnet and the support ring is not uniform, so that sufficient vibration cannot be generated over the entire outer wall of the cover, and a satisfactory haptic effect cannot be obtained.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a high-powered sound sensor that can obtain a sufficient bodily sensation vibration and at the same time can sufficiently transmit low vibration to the body.
