Description

Vibration tangible chair system using vibrator speaker mechanism {VIBRATION LIKE CHAIR SYSTEM USING VIBRATOR SPEAKER MECHANISM}

The present invention relates to a tangible vibration chair system, and to a vibration tangible chair system using a vibrator speaker mechanism that allows the human body to sense a sound heard through the human ear.

In general, there are two methods by which humans can hear sound, air conduction and bone conduction. The vibration of the tympanic membrane is transmitted to the screw-shaped cochlea through the ossicles, three bones located in the tympanic membrane, and the cochlea is filled with a fluid called lymph, and the vibrations of this fluid generate electrical signals. It is transmitted to the auditory nerve and the human brain recognizes the sound.

Since the bone conduction method omits the process of vibration passing through the eardrum and ossicles in the sound recognition mechanism, the vibration of sound is sent directly to the cochlea through the skull, so even if there is an abnormality in the eardrum or the ossicles, sound can be transmitted through bone conduction. Bone conduction speakers are used.

Various types and forms of bone conduction speakers are being developed, and most bone conduction speakers have a frame that forms the exterior, a voice coil that is installed inside the frame to form a magnetic field when an electric signal is applied, and the magnetic field of the voice coil. It consists of at least one magnet that interacts with and vibrates with a certain frequency, and a vibrating body that transmits the vibration of the magnet to the human body. Accordingly, when an electrical signal is applied to the voice coil, the voice A magnetic field proportional to the strength of the electrical signal is formed in the coil, and when the magnetic field interacts with the magnet, the magnet vibrates with a predetermined frequency in the vertical direction. As these vibrations are output through the vibrating body and transmitted to the human body, the human body recognizes a predetermined sound signal.

The advantage of such a bone conduction speaker is that there is no difficulty in hearing even after using it for a long time, and it is possible to simultaneously listen to external sounds through airway hearing and sound through bone conduction, so that sudden dangers can be dealt with. In addition, it is possible to communicate more accurately than a method using a general speaker even in a noisy environment. The application fields of these bone conduction speakers are widely used in communication devices for the hearing impaired, multimedia home appliances, Internet phones, Bluetooth headsets for mobile phones, and military use, and bone conduction earphones or earphones can be implemented including bone conduction speakers. .

In the bone conduction type earphone or earphone, the bone conduction speaker does not have any difficulty in hearing even after using it for a long time, so it is suggested as an alternative to the speaker method to prevent or reduce noise-induced hearing loss. It is suggested as an alternative to prevent safety accidents because it is possible to simultaneously listen to sounds through It is being considered and commercialized as an alternative that reduces the influence of external noise without blocking external noise by sending it and delivering it and enables more accurate communication than when using a general speaker.
