DESCRIPTION JP2001309473
[0001]
FIELD OF THE INVENTION A method of using an air vibrating microphone
[0002]
2. Description of the Related Art A conventional vibration microphone is a method of directly
vibrating vibration from a vibration source and converting it into an electric signal.
[0003]
SUMMARY OF THE INVENTION It is an object of the present invention to convert into a
waterproof vibration type microphone by using an air vibration type microphone generally used.
[0004]
In order to convert an air vibration type microphone into a vibration type microphone, an air
chamber is provided at a position in contact with a vibration source to vibrate air in the air
chamber and operate the air vibration type microphone. Let it be a means to solve the problem.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION A method of disposing an air vibration
microphone supported by a vibration preventing material in a container of plastic or the like
suitable material, and converting only the vibration of a vibration source in contact with an air
chamber into an electric signal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention
will be described with reference to the drawings. In FIG. 1, 1 is case A, and 1-a is convex for easy
contact with the portion in contact with the vibration source. The case A is thinned so that air
vibration is transmitted to the air.
[0007]
A case B is well meshed with the case A so as to be waterproofed, and has an outlet for an
electrical signal output cord.
[0008]
A microphone support 3 is made of a vibration-damping material or an appropriate material, and
an air chamber can be configured to be in contact with the top of the back side of the case A.
[0009]
4 is an air vibration type microphone, generally an electret microphone, but a dynamic type
microphone and a ceramic type microphone can also be used.
[0010]
5 is shared by the air chamber 5 with the microphone support of 4 and is in contact with the
back side of the top of 1 case A, and the air chamber is provided, the vibration from the vibration
source in contact with 1-a As the air vibrates, the air vibrating microphone becomes a vibrating
microphone.
[0011]
6 is an outlet of the cord for drawing out the electric signal.
[0012]
In 1-b of FIG. 2, the portion 1-a is made of a vibration-damping material, and the upper portion is
made thin to transmit external vibration.

FIG. 3 shows the place to be used, and 7 is an example of using it as a bone conduction
microphone using vibration of a head bone at the head portion.
[0014]
8. The buccal area is an example where both bone conduction and skin vibration microphones
can be used, which can utilize the vibration of the cheekbone and skin of the cheek.
[0015]
9 Throat junction is an application example as a vibrating microphone that utilizes skin vibration
of the throat
[0016]
Although not shown in the drawings, this microphone is not efficient but is characterized in that
it can be used as a general waterproof microphone as a general audio microphone. [0016] Thus,
a throat microphone, a skin microphone, a bone conduction microphone, etc. This makes it
possible to block out external noise and communicate in noisy places.
Since an air vibration type microphone can be used, a mass-produced product can be used, so it
can be manufactured at a lower cost than conventional vibration type microphones.
[0017]
The present invention is characterized in that it can be used inexpensively in many aspects of
complete waterproofing by creating an air chamber and inserting a general air vibration type
microphone therein.
