DESCRIPTION JPH09307614
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
simplified transmitter for mobile phones such as mobile phones and PHS (simple mobile phones).
[0002]
2. Description of the Related Art Recently, mobile phones such as mobile phones and PHSs are
rapidly spreading, and the use population thereof is increasing year by year. At the same time,
when using a mobile phone in a public transportation such as a train or Shinkansen, in a theater
or cinema, or during a meeting, speaking voice may be annoying to the surroundings and cause
social problems. I'm starting. This is because the size of the terminal of a mobile phone such as a
mobile phone or PHS is miniaturized, and as a result, the distance (dimensions) between the
receiving unit (the built-in portion of the speaker) and the transmitting unit (the built-in portion
of the microphone) ) Is short, and when the receiver is put on the ear, the transmitter becomes
far from the mouth, which is caused by speaking in a loud voice.
[0003]
In order to solve the above problems, an earphone microphone for mobile phones has been
developed. A conventional earphone microphone generally comprises an earphone and a

microphone and a plug electrically connected by a cord, and in use, the terminal is worn while
the plug is connected to a jack (plug insertion port) of the terminal. It is stored in a pocket etc.,
and the earphone is inserted into the ear hole and the microphone is hung down on the chest or
fixed in the chest with a tie pin for talking.
[0004]
Since the above-mentioned earphone microphone generally adopts a sound collecting type
microphone, it seems that the above-mentioned problem caused by the loud voice can be solved
once by making a call using this earphone microphone.
[0005]
However, it is generally unfamiliar to speak by hanging down the microphone or fixing it to the
chest, so I hate to feel psychologically uneasy and the mobile phone terminal is in the pocket etc.
Because it is stored and can not be seen from the outside, it is difficult to tell that it is in a call on
a mobile phone, and people around you may seem suspicious.
Also, since the conventional earphone microphone is open around the microphone and talks to
this microphone, even if it is a small voice call, the voice can be heard around. Therefore, using
the above-mentioned conventional earphone microphone has not been able to solve the problem
of annoying people who are very close.
[0006]
Since the present invention has been made in view of the above situation, it solves all the abovementioned problems caused by the call, the problem of psychological anxiety during the call, and
the above-mentioned various problems. It is an object of the present invention to provide a
portable telephone for mobile telephones.
[0007]
SUMMARY OF THE INVENTION In order to achieve the above object, the mobile telephone
simple telephone transmitter according to the present invention is a sound leakage prevention
device which abuts on the user's mouth to prevent leakage of voices uttered by the user. A
microphone provided in the preventer, a cord electrically connected at one end to the
microphone and led out of the preventer, and a plug electrically connected to the other end of
the cord; It is characterized in that the plug is connected to a mobile telephone terminal for use.

transmitter according to claim 1, the sound leakage preventive device is constituted by a cup-like
body.
The invention according to claim 3 is characterized in that, in the mobile telephone simple
transmitter according to claim 1, the sound leakage preventive device is constituted by a
cylindrical body having one end opened.
[0009]
[Functions] The simplified mobile telephone for mobile telephone according to the present
invention connects the plug to the jack (plug insertion port) of the terminal, holds the terminal
with one hand, applies the receiver to the ear and sounds The leak preventer is held by the other
hand, pressed against the mouth and abutted to make a call. According to the present invention,
the following action is exerted.
As you talk by covering the mouth with the sound leakage prevention device, it prevents the
sound from leaking outside. Since the user holds the terminal by hand and makes a call, it can be
known from the outside that the user is talking on a mobile phone. The terminal can be held by
one hand and put on the ear, and the sound leakage prevention device can be put on the mouth
by the other hand so that speech can be made without leaking outside, so that a sense of
psychological security can be given and the surroundings by the speaking voice Can solve the
problem of

view of the same simplified telephone, and FIG. It is explanatory drawing which shows the use
condition of a transmitter. The simplified mobile telephone transmitter 1 includes a sound
leakage prevention device 11, a microphone 12 provided in the prevention device 11, and a plug
14 electrically connected to the microphone 12 by a cord 13. The plug 14 is used by connecting
to the terminal 2 of the mobile telephone.
[0011]
The terminal 2 can adopt an arbitrary type or model of a mobile phone such as a cellular phone
or PHS, 21 is a receiver (incorporating part of a speaker), 22 is a transmitter (incorporating a
microphone), 23 is A display unit such as a message or the like, 24 indicates a dial push button
or other operation button, 25 indicates an antenna, and 26 indicates a jack (the insertion port of
the plug 14). This terminal 2 is a known one, and in the normal case, it is used as it is as a mobile
telephone terminal.
[0012]
The sound leak preventer 11 of the simplified transmitter 1 is used in contact with the mouth of
the user 3 (see FIG. 3), and the preventer 11 of this embodiment is constituted by a circular cupshaped body 15 Things are disclosed. The preventing device 11 covers the mouth of the user 3
and speaks in such a manner that the voice uttered by the user 3 does not leak from the
periphery of the opening 16 of the cup-like body 15 to the outside. There is no particular
limitation on the size of the opening 16, but in general, the inner diameter of the opening 16 is
likely to be set in the range of about 25 mm to 60 mm. The stopper 11 may be formed of a cupshaped body such as an oval or the like, or it may be freely formed of a cylindrical body such as a
circle or an oval having one end opened.
