DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for
attaching audio equipment, and more particularly to a windscreen apparatus for acquiring a
recording input signal which can be arbitrarily switched to a plurality of types of recording and
reading aspects of the tape recorder. For example, self-set tape recorder with radio L The use of
the tape recorder L has been considered, and especially how to record radio programs directly on
tape, how to record microphone signals with wired hand microphones, and built-in radio wave
generator in hand microphones. This microphone also uses O to transmit a microphone signal as
a radio wave, and this is received by the radio of the tape recorder with radio and recorded on
the received signal tape. The usage is connected to the recording input terminal of the tape
recorder. It is conceivable that the output signal of the sound reproducer can be recorded on a
tape by inserting the plug of the recording wire into the earpiece jack of the sound reproducer
such as a television or stereo storage. Although various usages such as those described above are
considered, in order to make them effectively effective, it is necessary to acquire recording input
signals each time (wired hand microphone, wireless hand microphone, recording wire plug, etc.)
Replacement switching work is troublesome. SUMMARY OF THE INVENTION The present
invention eliminates the above-mentioned drawbacks, and provides an attachment of an audio
device which can easily and accurately change the acquisition means of the recording input
terminal. The example is custom-made below. Microphone 7o (referred to as a J2I lower
microphone) Fi used in the invention of the present invention As shown in FIG. 1, it comprises a
sound receiving part 11, a body part 12 and a connecting part 13, and the connecting part 13

has a jack 14 Is attached. This jack 14 is the body! ! It is housed in a part of 1512 and is used to
lead the output signal of the transducer 5 to the outside of the microphone by being coupled
with the output terminal of the transducer 15 and the lead wire 16 by V, . A radio wave
generator 11 can be detachably coupled to the coupling portion 13 of the microphone 10. That
is, the connecting portion 18 of the radio wave generator is provided with a plug 19 which can
be connected to the jack 14 of the microphone 10. By inserting the plug 19 into the jack 14 of
the microphone 10, the microphone 10 and The respective coupling portions 13 and 18 of the
radio wave generator 11 are in close contact and mechanically and electrically coupled. The
radio wave generator 17 is coupled to the microphone 10 (the shape of the microphone is
considered to be natural in design-like connection with the shape of the microphone). For
example, the radio wave generator 17 and my) ylo The end face of each of the joint portions 13
and 18 is completely open, and so on.
It is designed to hold part III in hand. The radio wave generator 17 has a radio wave signal
generation circuit unit 20 including an oscillation circuit, a modulation circuit, a power supply,
etc., and the plug 19 is connected to the input side of the circuit unit 20 by a lead 21. Leads 22
are coupled to the side. The output lead 22 is further coupled to the antenna wire 23.
Furthermore, a switch member is provided on the body portion 24 of the radio wave generator
17 and only the operating member 25 is provided so as to protrude outside the body portion 24.
In this switch member, as shown in FIG. 2, in the first stage switching position OFF of the
movable contact piece 30 (sliding in the direction of the arrow in the figure), the eight step
switching function is a J function. The power supply E of the unit 20 is set to [0FFJ, and the input
signal from the input terminal (plug 19) is directly applied to the radio wave signal generation
circuit unit 20 at the second stage switching position @IMJO. In switching position 11AUX of the
eye, switching 1 # is continued such that the input signal from the input terminal (plug 19) is
applied to the forward radio wave signal generation (b) path portion 20 via the attenuation
element, for example, resistor 3a. . That is, in the case where there is a difference in magnitude of
the level of the signal applied to the input terminal, the switching operation is used, and there are
other usages as described later. One lag 19 of the radio wave generator 11 is, for example, sound
reproduction t such as a television, a disk record reproduction machine or another tape deck.
This sound reproducer has a structure that can be releasably coupled to an earphone jack or
lineout jack 27 provided to IrlSxe and can be coupled to the sound reproducer 26 in addition to
being connectable to the microphone 10 The output signal of the twenty-six is converted into a
radio wave so that it can be broadcasted (on air). Furthermore, the jack 14 of the microphone 10
is also connected to the end plug 29 of the recording wire connected to the tape recorder 28 of
the company 14 in a detachable manner. The accessory device of the acoustic electronic device
according to the present invention has a structure in which the radio wave generator with the
plug is made detachable to the microphone with the jack, and the plug of the radio wave
generator is detachable with the television and the earphone jack of the storage battery. Since
the jack of the microphone is further provided with a detachable structure for the recording wire

end plug connected to the tape recorder, the following usage can be made. How to use (1): The
radio wave generator 11 is connected to the microphone 10, and the microphone signal is
transmitted to a radio placed as a wireless hand microphone and placed at a remote place and
received by the radio.
If this radio is a radio cassette tape receiver with radio, the received signal can be immediately
ringed by the tape recorder. In this case, the switch position of the switch member company's
second stage of the radio wave generator 11 is switched to the switching position so that the
microphone output signal is directly output to the radio wave signal generation circuit unit 20.
Obviously, when temporarily stopping the microphone output, the switch member changes the
switching position of the eighth stage @ AUXK @. This is to prevent ambient noise picked up by
the microphone from being sufficiently attenuated by the level attenuator 31π and applied to
the input side of the radio wave signal generation circuit unit 20, and the power of the radio
wave generator 11 is operated without turning OFFJ. This is because there is no input signal in
this state and only this carrier wave is generated to prevent the generation of noise called data
on the receiving side. If the switch member is switched to the first stage 0FFJ position just
because the microphone output is interrupted, the power of the radio wave generator 11
becomes (0FPJ, so the operation of the radio wave generator 17 is stopped and the radio wave
is stopped. Will not fly at all. As a result, the radio receiving side has power "ON" and although
there is K in the receiving state, there is no received radio wave and noise called "day" is
vigorously generated. Therefore, when the radio output is ringing, this noise is recorded on the
tape, and it is not preferable because it becomes very audible during reproduction. How to use :)
Connect the recording wire end plug 29 of the tape recorder 28 to the microphone 10 and apply
a microphone signal to the tape recorder 28 by the wire and also record a radio program when
the tape recorder 28 is a tape recorder with a radio You can enjoy mixed recording play of socalled radio program and microphone signal. How to use it): The microphone 10 is wired to the
tape recorder with radio as in method (2), and the radio wave generator 17 separated from the
microphone 10 is connected to the earphone jack 27 of the television this time to fly the
television output by radio waves. By receiving this by the radio of the radio-equipped tape
recorder 28 and recording the received signal by the tape recorder, it is possible to freely join
one's own voice or singing voice to a television program. In the case of the ring, the switch
member of the radio wave generator 17 attenuates the switching position AUXK switching input
signal level of the eighth stage by a predetermined amount to bring the input signal level to the
radio wave signal generation circuit unit 20 to a predetermined level. As described above, if the
auxiliary device of the present invention is used, the input signal power to the radio or to the
tape recorder with radio can be easily changed by simple connection switching, and it exerts a
great effect as a recording signal acquisition means for the cassette tub recorder with radio in
particular. The function of the tape recorder with radio can be fully utilized, and enjoyable
acoustic play is possible.
