DESCRIPTION JPH06225376
[0001]
FIELD OF THE INVENTION The present invention relates to wireless microphones or
conventional microphones.
[0002]
In recent years, wireless microphones not bound by codes have come to be used from theaters
and studios to lectures, classrooms, shops and banquet halls. Since the microphone side is a kind
of wireless transmitter, it naturally involves operations of turning on and off the power.
According to market demands, microphones with switches are required for applications where
users of the microphone themselves operate switches, such as banquet halls, and for applications
operated by specialized coordinators such as broadcast stations and theaters, no switches are
required to prevent malfunctions. ing.
[0003]
Conventionally, according to each of the above applications, the switch-equipped microphones
shown in the plan view of FIG. 3A and the switch-free microphones shown in the plan view of
FIG. 3B have been separately manufactured.
[0004]
However, with the above-mentioned conventional wireless microphones, it is difficult to expand

the same product in a wide variety of markets because there are switches and switches
independently. Had the problem of requiring an assortment of
[0005]
SUMMARY OF THE INVENTION The present invention solves the above-described conventional
problems, and provides an excellent microphone capable of changing both with and without a
switch, which can be changed with a single operation and with a small amount of simple work.
[0006]
In order to achieve this object, the microphone of the present invention comprises means for
covering a switch placed in a recess in the outer wall of the microphone body and means for
fixing the means for covering the switch. It has a configuration.
[0007]
According to this configuration, the switch-equipped microphone can be formed by removing the
means for covering the switch, and the switch-less microphone can be provided by attaching the
means for covering the switch and fixing the means for covering with the means for fixing .
[0008]
Embodiment 1 An embodiment of the present invention will be described with reference to the
drawings.
[0009]
FIG. 1 is a perspective view showing the configuration in the first embodiment of the present
invention.
In FIG. 1, 1 is a wireless microphone main body.
1a is a screw hole provided on the back surface of the wireless microphone body 1, 2 is a power
switch provided in a recess on the back surface of the wireless microphone body 1, 3 is a switch
cover, 3a is provided on the back surface of the switch cover 3 A projection 4 is a screw for
fixing the switch cover 3, and a ring 5 prevents the screw 4 from coming off the switch cover 3.

The operation of the wireless microphone configured as described above will be described with
reference to FIG.
First, in the state of only the wireless microphone main body 1 with the switch cover 3, the screw
4 and the ring 5 removed, the wireless microphone main body 1 can be operated or stopped by
operating the power switch 2 and works as a switch-equipped microphone .
Next, by screwing the screw 4 into the screw hole 1 a of the wireless microphone body 1, the
switch cover 3 is attached to the rear surface of the wireless microphone body 1.
At this time, the projection 3a on the back surface of the switch cover 3 is in contact with the
knob of the power switch 2 to hold the power switch 2 in the ON state to prevent a malfunction.
In this state, it works as a switchless microphone.
[0011]
As described above, according to the present embodiment, the combination microphone with and
without switch is provided by including means for covering the switch provided in the recess of
the outer wall of the microphone body and means for fixing the means for covering the switch.
can get.
[0012]
(Example 2) FIG. 2 shows an example of a normal microphone having a cord, wherein (a) is a
perspective view showing a configuration when used as a switch, and (b) is a perspective view
showing a configuration in use without a switch. It is.
2 (a) and 2 (b), 21 is a microphone body, 21a is a female screw provided on the rear surface of

the microphone body 21, 21b is two groove holes provided on the side of the microphone body
21, 22 is a microphone body. An audio switch provided in a recess on the side surface, and a
cover plate for covering the audio switch 22, has a semi-cylindrical shape, and straight end edges
are bent inward at a right angle so as to fit in the slot 21b. ing. Reference numeral 24 denotes an
annulus having an external thread which can be screwed into an internal thread 21a provided on
the microphone body 21.
[0013]
In the second embodiment configured as described above, (a) of FIG. 2 is one in which the ring
24 is screwed into the female screw 21 a in a state where the cover plate 23 is removed, and the
voice switch 22 is operated to produce an audio signal. The output can be turned on and off. If
the type of microphone requires a power supply such as a condenser microphone, it also doubles
as a power switch. In (b), after the ring 24 is removed once, the voice switch 22 is inserted, and
then the cover plate 23 is inserted along the slot 21b on the upper side, and the ring 24 is
screwed into the female screw 21a again It can be used as a switchless microphone.
[0014]
As described above, the present invention comprises the means for covering the switch installed
in the recess of the outer wall of the microphone body and the means for fixing the means for
covering the switch, and removing or attaching the means for covering the switch It is possible to
realize an excellent microphone that can be used both with and without a switch.
