DESCRIPTION JP2001016672
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
radio for the purpose of sensing a vocal cord vibration and converting it into an electrical signal
for communication in a mobile phone or other wireless communication device. The present
invention relates to a handset for communication equipment.
[0002]
2. Description of the Related Art There has been proposed an invention of an auditory machine
which attempts to realize voice and sound through the skin, muscles and bones of a person
(Japanese Patent Application Laid-Open No. 10-285697). Also, as an element for converting
mechanical displacement into an electrical signal, for example, piezoelectric ceramics are widely
known.
[0003]
Although techniques for vibration of the skin and the like are known, their use in communication
devices is not yet known. Similarly, techniques are known for elements that convert mechanical
displacements into electrical signals, but the technical idea of converting the above-mentioned
techniques from human vocal folds into electrical signals and transmitting them from
communication equipment is known. It was not.

SUMMARY OF THE INVENTION According to the present invention, since a microphone having a
vocal cord vibration sensing function is attached to the support means on the neck, the
microphone is set in a place where vocal cord vibration can be easily captured. It succeeded in
converting the vocal cord vibration into an electric signal without using voice and achieving the
purpose of transmitting from a communication device such as a mobile phone to which the
output terminal of the microphone is connected.
[0005]
That is, according to the present invention, a microphone having a vocal cord vibration sensing
function is attached to the support means on the neck, and the output terminal of the
microphone and the input terminal of the earphone are inserted for inserting into the connection
hole of the wireless device. It is a handset for a wireless communication device characterized in
that the support means for the neck portion is a silicon-coated stainless steel frame.
[0006]
Also, the cords of the microphone and the earphone are carried on the support means on the
neck, and the microphone is made of ferroelectric ceramics.
[0007]
In the above-mentioned invention, although a stainless steel frame coated with silicon is used as
a means for supporting the neck, it is not limited to this.
The point is that it is only necessary that the microphone be held in place in the neck with
appropriate pressure, and the frame is preferably made of an elastic material, light in weight, and
not deformed during use.
[0008]
Although the microphone and earphone cords in the present invention are relatively long, by
attaching them to the frame, there is no possibility that they will get stuck in other objects during
use or interfere with the operation of the transmitter / receiver.

The present invention can be used for portable telephones and personal computer
communications and other voice receiving / wireless communication devices.

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a
microphone having a vocal cord vibration sensing function is attached to a support means to the
neck (for example, a frame attached to the neck) and inserted into a connection hole of a wireless
device. The output terminal of the microphone and the input terminal of the earphone are
integrally provided so as to be able to be connected to the connection hole of the communication
device.
[0011]
The microphone in the present invention is, for example, one obtained by polarization treatment
of a ferroelectric ceramic, and uses an element represented by Pb (Zr · Ti) O 3 (PZT).
The PZT is a solid solution of perovestite type ferroelectric PbTiO3 (tetragonal) and
antiferroelectric PbZrO3 (rhombohedral), and has a characteristic that its crystal system changes
at almost the same composition, and mechanical signal Is good, but the present invention is not
limited to this conversion element, and a conventionally known conversion element can be used.
[0012]
EXAMPLE An example of the present invention will be described with reference to FIGS.
[0013]
A microphone 2 having a vocal cord vibration sensing function is fixed to one end of a stainless
steel frame 1 curved in a plane arc shape, and its cord 3 is attached to the stainless steel frame 1
by a stop ring 4.
[0014]

The cord 6 of the earphone 5 and the cord 3 are attached to the stainless steel frame 1 by a stop
ring 7.
A terminal 9 connected to a connection hole (not shown) of the portable telephone 8 is
connected to the end of the cords 3 and 6 to configure the handset 10 of the present invention.
[0015]
The handset 10 of the present invention can be used by attaching the stainless steel frame 1 to
the neck 11 as shown in FIG. 2 and supporting the mobile phone 8 with the hand 12 or putting it
in a pocket it can.
[0016]
The stainless steel frame 1 in the above-mentioned embodiment has an appropriate degree of
curvature so that the microphone 2 can correctly capture vocal cord vibration when worn on the
neck.
[0017]
Therefore, the shape and length of the stainless steel frame 1 should be sufficient to achieve the
above-mentioned purpose, and be sized so that it can be easily worn by an average person on the
neck, but since it is originally an elastic material, it deforms. A frame of the same dimensions can
be applied to and worn by most people.
[0018]
According to the present invention, since vocal cord vibration can be captured and converted into
an electrical signal to be transmitted, noise is less likely to be picked up even if the noise at the
calling place is loud, and accurate conversation can be achieved. There are effects that can be
done.
In addition, people who have difficulty in speaking out and those who have aids in their throat
can easily communicate their intentions.
[0019]

Next, since the signal is received by the earphone, there is an effect such that there is no
possibility that the noise at the receiving place may disturb the call.
[0020]
Furthermore, there is an effect that it is not necessary to use a hand for both transmission and
reception, and it is possible to continue transmission and reception even with other work with
both hands.
