DESCRIPTION JPH0720793
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
cordless microphone system for a tourist bus karaoke consisting of a cordless microphone and a
receiving device for receiving the output signal of the cordless microphone, and in particular, to
the receiving device side The present invention relates to a cordless microphone system having
noise removal means for removing specific noise and a plug connected to a plug connection jack
of a microphone provided in a car.
[0002]
2. Description of the Related Art A conventional microphone for karaoke provided for sightseeing
buses is wired, and a lead wire of a predetermined length is connected to the output side of the
microphone. A plug is provided at the tip. On the other hand, a jack for receiving the plug of the
microphone of the karaoke apparatus is installed at an appropriate place in the car of the
sightseeing bus, and the microphone is connected to the karaoke apparatus by inserting the plug
of the microphone into the jack. The output signal of is input to the karaoke apparatus.
[0003]
According to the prior art described above, in use, the lead wire of the microphone is pulled
around the foot or seat of another passenger. There were a number of problems such as the need
for the cooperation of other passengers and the fact that the lead wire being routed was a
hindrance when turning.

The present invention has been made in view of the above problems of the prior art, and the
purpose of the present invention is to use a cordless phone as a microphone, and mount a
receiver for receiving the output signal of the cordless phone to the jack. To provide a cordless
phone system that eliminates the need for cordless microphone leads.
[0005]
SUMMARY OF THE INVENTION In order to achieve the above object, the cordless microphone
system in the present invention comprises a cordless microphone and a receiving device for
receiving an output signal of the cordless microphone, and the receiving device described above
And a plug connected to the output side of the receiving circuit is protruded outside the case. is
there.
[0006]
Preferably, the noise removal means removes vehicle-specific noise when the output signal of the
cordless microphone is a radio wave.
[0007]
Preferably, the noise removing means is a polarizer when the output signal of the cordless
microphone is infrared.
[0008]
Furthermore, the plug is connected to a plug connection jack of a microphone provided in the car
of the sightseeing bus.
[0009]
The present invention is extremely simple and inexpensive because the receiver for receiving the
output signal of the cordless microphone is electrically connected to the existing jack for
inserting the plug of the wired microphone. A cordless microphone can be used for this, and as a
result, many problems with the lead wire routing of the conventional microphone can be solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present
invention will be described below based on the drawings shown as an embodiment.
FIG. 1 is a perspective view of a receiving apparatus for receiving an output signal of a cordless
microphone, in which 1 is a case, and a plug is in contact with one side surface of the case 1.
The plug 2 is, for example, for plugging directly into a jack 3 for a plug of a wired microphone
already installed in the car 3a of the tourist bus.
[0011]
In the case 1 described above, the receiving means of FIGS. 2 and 3 described later are
incorporated.
FIG. 2 shows an outline of the receiving means when the output signal of the cordless
microphone 4 is a radio wave.
The configuration is connected to the antenna 5 in the order of the RF tuning circuit 6, the high
frequency amplifier 7, the low frequency amplifier 8, and the output terminal, ie, the plug 2.
The known receiving means are provided with known noise removal means 9 for removing carspecific noise.
[0012]
FIG. 3 shows a schematic receiving means when the output signal of the cordless microphone 11
is infrared.
The configuration is as follows: an output signal from the cordless microphone 11 at the front of
the light detection means 12 of the known reception means connected in the order of the light

detection means 12, the amplifier 13, and the output terminal, ie the plug 2. An extraneous-part
removing means 14 is disposed, which is made of a known polarization means for transmitting
only infrared light of a predetermined wavelength as the light source and for blocking, for
example, sunlight and the like.
[0013]
In the case of using the cordless microphone 4 which uses radio waves as an output signal, the
receiving apparatus of FIG. 1 incorporating the above-mentioned receiving means of FIG. 2 is
used.
That is, the plug 2 of the receiving apparatus is inserted into the jack 3 already installed for the
plug of the wired microphone. (Or put in advance. Under this condition, by turning on the switch
of the cordless microphone 4, its output signal is transmitted as a radio wave. This is received by
the receiving device and finally supplied to, for example, a karaoke device via the plug 2 and the
jack 3. In this case, the noise specific to the vehicle is removed by the noise removal means 9.
[0014]
When using a cordless microphone 11 whose output signal is infrared light, the receiver shown
in FIG. 3 is used. That is, the plug of the receiver of FIG. 1 is inserted into the existing jack 3. (Or
put in advance. Under this condition, by turning on the switch of the cordless microphone 11, its
output signal is transmitted as infrared light. This is received by the receiving device and finally
supplied to, for example, a karaoke device via the plug 2 and the jack 3. In this case, light rays
that become noise sources such as sunlight are removed by the noise removal means 14.
[0015]
Although merely plugging the plug 2 into the jack 3 may cause the plug 2 to slip out of the jack
3 due to vibration or the like generated during travel of the tourist bus, an optional retaining
means is provided although not shown. It is done. The amplifiers 8 and 13 in FIGS. 2 and 3 may
be digital or analog.

[0016]
According to the cordless microphone system of the present invention, the lead wire of the
conventional microphone is not routed, and therefore, it is only necessary to pass the
microphone when setting the microphone and when passing the microphones of the passengers.
Because it is good, the transfer operation is extremely easy. Also, simply plugging the case into
the existing jack can receive the signal from the cordless microphone, and thus can be used
without improving the sightseeing bus. Also, when the output signal of the cordless microphone
is a radio wave, the noise removal means removes the noise specific to the vehicle. In addition,
when the output signal of the cordless microphone is an infrared ray, the noise removal means
has many advantages such as removal of signals of wavelengths other than the wavelength of the
above signal.
