DESCRIPTION JP2003070084
[0001]
BACKGROUND OF THE INVENTION The present invention converts an electrical signal of sound
sent to an electroacoustic transducer into mechanical vibration, further guides it into acoustic
vibration, and radiates it again into space as sound. The present invention relates to a device
which attempts to transmit mechanical vibration directly to human skin as subtle vibration of
sound by slightly changing the conventional method.
[0002]
2. Description of the Related Art An electroacoustic transducer is intended to convert an
electrical signal of sound sent into mechanical vibration, guide it into acoustic vibration, and
radiate it again into space as sound. And shall be defined in JIS.
[0003]
Problem to be Solved by the Invention The term "sound" refers to sound that is caused by the
vibration of an object causing air to vibrate.
When sound waves are transmitted to the human body, people always receive this throughout
the body. It does not mean that only the tympanic membrane resonates and feels. People can
receive sound other than the tympanic membrane even if they are stimulated by the vibration of
the sound.

According to the present invention, mechanical vibration caused by the electrical signal of the
sound sent to the electroacoustic transducer is directly transmitted to human skin as a subtle
vibration of the sound to artificially stimulate the vibration of the sound. This is intended to
reproduce and emphasize the scene where the original sound was recorded.
[0005]
According to the present invention, the mechanical vibration is directly transmitted to the human
skin as a subtle vibration of sound, with a slight change of the conventional method of leading to
the acoustic vibration from the mechanical vibration of the electroacoustic transducer. Purpose.
[0006]
Means for Solving the Problem The diaphragm of the electroacoustic transducer is directly
pressed against the skin of a person to transmit subtle vibrations of sound.
However, the diaphragm does not fit well on the skin.
Therefore, a rubber-like elastic body that is easy to conform to the skin and transmits vibration
well is attached to the diaphragm. The rubber-like elastic body may also be as follows. The
diaphragm is made into a double structure and the fluid is filled inside. The surface of the double
structure to be pressed against the skin is a rubber-like film.
[0007]
By attaching a rubber-like elastic body, the roundness of the skin is accepted and the contact
surface is made gentle. Even if the pressure to be pressed slightly changes, it can follow.
Moreover, vibration is transmitted well.

BEST MODE FOR CARRYING OUT THE INVENTION The device of the present invention is set in
an electroacoustic apparatus such as a radio cassette tape coder (radio cassette) and used in
combination with a conventional speaker to be heard through the ear. However, volume switches,
tone switches, etc. are separate. The device according to the present invention is used as an
auxiliary device when enjoying music by attaching it to a hand or foot with a band or touching it
with a finger.
[0009]
According to the present invention, when the apparatus of the present invention is set in an
electroacoustic apparatus and music is enjoyed, the music radiated from the conventional
speaker and heard through the ear, and the subtleties of the music transmitted from the
apparatus of the present invention through the skin Because vibration and an effect can be felt as
an integral effect, more realism is obtained. Sometimes I am impressed.
[0010]
When the device of the present invention is set on a NES or the like to enjoy the game, the sound
heard through the ear, the subtle vibration of the sound transmitted through the skin, and the
screen can be felt as an integral effect, so that the further Get a sense of presence.
[0011]
By using the device according to the present invention, deaf persons who have been thin in music
in the past can also receive tones such as classical music and jazz on their skin, and can fully
enjoy the music atmosphere.
[0012]
In addition, if the device of the present invention is used, deaf persons can also go to a music
concert.
Of course, you need to get an electric signal from the organizer.

Surely, you will be impressed by classical music, jazz and big applause.
[0013]
Further, by using the device of the present invention, the hearing impaired person can also
accept the tone of music on the skin, take a rhythm, and participate in the performance.
