DETAILED DESCRIPTION OF THE INVENTION The present invention relates to wireless
microphones, and in particular, to a lumped constant antenna such as a ferrite antenna. 14
bundles, wireless microphone, micro, t f f 'and sending (,; machine + this one integral integral 2
even if integral type, microphone element 1' and transmitter body microphone (1) 32 There are
some which can also be used as a minute k 9 connected via a cord. In such a wireless
microphone using a lumped-constant antenna such as a ferrite antenna, one end of the lumpedloss antenna is connected to the output side of the transmission circuit, and the other end is
connected to one common line. One end of the family was connected to the input side of the
transmission circuit, and the other end was connected to one common line. Therefore, when this
wireless microphone is used as a separate type, the high directional technology flow flowing
through the ferrite antenna 1) is common to the flow through the microphone cord via +, and the
microphone cord functions as an antenna, as an integrated type In comparison to the case of
using it, the transmission radio wave was strong. When using the same wireless microphone as a
separate unit, as well as when it is used as a single unit, it is sent. E of the radio wave was
different. ? ? ? ? ? ? ? ? ? ? ? ?? ?? ? ? ? ? ? ? ? ? ? ? 1 ? ? ? ? ?

(2) j) will be described. FIG. 1 shows a first embodiment. Reference numeral 2 denotes a
transmitter main body, and a printed circuit board 4 is accommodated in the circular portion. A
low frequency increasing circuit 6, an oscillation modulating circuit 8 and a high frequency three
circuit 10 connected in series are formed on the printed circuit board 4. Further, the printed
circuit board 4 is also formed with a + side common power source clothes 12 and-power source
common lines 14 for supplying operating current to these circuits. Each of these circuits is
configured in minus one step. The + side common power source '@ 12 is connected to the
positive side electrode of the battery 11 i 16, and the ?11 111 power source common line 14 is
connected to one side electrode of the battery 16. The output 1lIlj of the high frequency circuit
1o is connected to one end of the ferrite antenna 18, and the other end is connected to the
source 1j. It is connected to w12. The low frequency amplification circuit 60 input side 1 is
connected to one terminal 22 of the jack 20 provided in the transmitter main body 2 via the high
frequency blocking coil 18, and the mesh 24 of that capability The 1st power supply is
connected to 4g14.
A microphone cord 28 has a plug 6 ░ at one end thereof; IXf-f. The plug 3o can be inserted into
the jack 2 (3) j. Also, a jack 32 is attached to the other end of the microphone cord 28. This jack
32 is identical to the jack 20. The 34U74 crophone element is, for example, a dynamo type, and
further has a plug 36. The plug 36 is the same as the plug 30, and one end r of the microphone
element 34 is connected to one of its terminals, and the other terminal of the microphone
element 34 is connected to the other terminal. Thus, by inserting the plug 36 of the microphone
34 into the jack 20, and by connecting the plug 36 to the jack 32 of the microphone core 128
and connecting the plug 30 of the microphone cord 28 to the jack 20 The microphone element
34 can be connected to the amplification circuit 6 and can be used as an integral type or a
separation type. In the wireless microphone configured in this way, the current flowing through
the ferrite antenna from the low frequency circuit lO flows to the common power supply line 12
during operation, so that (one quotient and one wave current hardly flows to the microphone 28
Microphone cord 28 does not function as an antenna. (4) FIG. 2 is the same as the first
embodiment except that the electret condenser type microphone element 38 having the Nchannel FET 37i is used as the impedance conversion element in the second embodiment ?. The
same reference numerals are given to the same parts and the description thereof is omitted. FIG.
6 shows the third embodiment, except that an electret condenser type microphone element 42
having a P-channel FET 40 is used as an impedance conversion element 1, and the other end of
the ferrite antenna is connected to one side power supply common line 14. The same as in the
first embodiment. The same reference numerals are given to the same parts and the description
thereof is omitted. The second and third embodiments 1 operate similarly to the first
embodiment, and even when used as a separated type, the low frequency current does not flow
in the microphone co-128 and it does not function as an antec. In these wireless microphones,
the Q power O end f of the microphone Jp (a gain between I and X and the input f of the # Jl'l 46
and the horse f not connected to the measurement) are connected to each other (5). Since the

other end of the ferrite antenna 18 is connected to the power supply common line of the
opposite polarity to the source common line, no high frequency current flows from the 7 elite
antenna 18 to the microphone coat 28 and the microphone cord 28 functions as an antenna иdo
not do.
Therefore, if this wireless microphone is adjusted so as to obtain the best radio wave strength
and the maximum radio wave power that can be used without a license according to the Radio
Law in the integrated state, it is possible to use as the separation type or Even if it is used as an
integral type, almost the same transmission and signal strength can be obtained. If the value of
the high frequency blocking coil 18.26 is appropriately selected, it is possible to make the
intensity of the transmitted radio wave the same. In the first embodiment, each circuit is
configured as -1-s, so the ferrite antenna 18 is connected to the + IIllI power supply common 1 и
line 12. However, when configured as + ground, the ferrite antenna 18 is m-power Connect to
common [14. 4. Brief description of the drawings (7) Fig. 1 shows the outline structure of the
