[Detailed Description of the Invention] The present invention housed a microphone reflex on
element! The amplification element has been incorporated in the main body of the equipment! 7
on K11 l is also 0, especially the amplification element built into the body (no direct connection
to the bias power supply, so that the microphone w ? on signal is taken out via the internal
resistance of the bias power supply) In addition to the above, the power supply of (1) 48-5873002 relates to a microphone in which it is incorporated in the connection plug of the microphone.
Well-known oH, one-man bus, etc. for operation guidance S)% p All-you-can microphone All-youcan-own hat Cap or body Attach it to a part and drive a bus, even 1k, but for passengers On the
other hand, the operation status section O guidance of the path is to be viewed. The sensitivity of
the microphone is enhanced by incorporating the amplification element integrally with the closetalking microphone used in the 7-man pass or the like. Therefore, in order to operate this
amplification element, it is necessary to use an IC power supply separately from Kit, and it is a
practice to use w) to use a normal dry battery as this power supply. In addition, since this dry cell
is integrated with the microphone 7 on-board weight light in the conventional example, the
microphone 7 on the main body is integrated with the microphone attachment or the like. It only
needs to be heavy, and it needs space and Ks structure to accommodate this, so it has the
disadvantage of operating (1nJ- Since the dry battery used for the microphone which made this
K-S) gradually becomes an O internal resistance gradually with the lapse of use time of O, when
taking out the microphone shift signal, the dry battery and the amplification element (The load
resistance is inserted, and the microphone signal must be cut out between the terminals of this
load resistance 1 и). In this way, for the turtle reason to connect between the main body of the
miterifon and the amplifier 20, the lead IIs seven wires are necessary, and two signal lines
connected to both the butterfly, the ground line and the above-mentioned load resistance are
necessary. Also, when wiring the wiring, many man-hours are required. Not only that, but
because it requires its own shield area by having two signal lines, it must be expensive in terms
of price and 'spring. Here, internal resistance as a bias power supply for the amplification
element incorporated in the main shock plan ? mic sophone & body '' 4B-58730-04Dl #,

season cO dry battery!
I u uon on the main body I cut off! It is intended to eliminate the above-mentioned 0JlOI & defect
at once in such a manner that it is incorporated in the connection plug of W7 ON. The present
invention is based on the illustrated embodiment-a concrete KI! Specifically, in FIG. 1, the
reference symbol MFiv is 7 on the main body, and the microphone 97 on the inside of the main
unit Ka-As an example, the electric condenser microphone element Cm of the electric Flet
microphone is incorporated, and this microphone element Cm0 If both ends are provided with
input bias resistance R +, both k. The resistor R... Is connected to the gate terminal of the FET

mercury battery EK @ also this battery In addition to mercury batteries, it is self-reliant to use
alkaline batteries etc., and the internal resistance of the battery E of C is 1 to 41 i as shown in
FIG. It is possessed. That is, the vertical axis of #I 211 indicates the internal resistance of the
battery and the usage time of the battery C, and the characteristic curve ^ shows that the internal
resistance is always constant Is) up to the maximum service life time HK. It indicates that the
internal resistance increases with the passage of time H. It is a turtle that requires the use of a
battery having the above characteristics, and at the dead end of the CO battery 10, the gold

48-5873 C-08 attachment fund so that it can be optionally attached to a part of a body with a hat
in the operation 1fK of a one-man bus. The present invention has the above-mentioned
construction:... Works as follows. That is, when the battery E is housed inside the covering case
P'O, and this case is attached to the insertion portion by the screw $ 181, the voltage of the
battery E6 causes the amplifying element Q to be connected via the line (2 and (2) Bias to
operating condition. ??????????????? + ? head (voice vibration company 91 is
converted to an electric signal by the microphone element CmK constituting this, this signal is
further amplified by the amplification element Q, and the signal line (? ? ? and (2) Is
introduced into the battery ?. Further, the signal #cIII here is taken out as a signal voltage from
both terminals of the load resistor R1 via the internal resistance "1w" of this battery, and this
signal voltage is sent via the DC blocking capacitor 32C. It is introduced into a separate amplifier
(not shown). +8) 48-58730-091) As described above, according to the present invention, in order
to operate the amplification element incorporated in the main body of the microphone ? ? 7 on
(a mercury battery with stable internal resistance and an alkaline battery are used ? Therefore,
even if the audio signal amplified by the amplifying element S) is taken out via the internal
resistance of the mercury battery or alkaline battery supplying the bias voltage of this amplifying
element, the warpage signal voltage is The number of lines to transmit the voltage is lower than
that of the conventional one, and the mercury battery t and alkaline battery are stored inside the
connection plug of the microphone. In the conventional type that was equipped with a dry cell in
1% of the microphone body, the microphone body is made of a lightweight member. It can,
therefore can be two very compact 4 overall.
