DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a
transmitter, and more particularly to a transmitter using a microphone unit. Recently, in order to
improve the performance of a telephone, there are an increasing number of telephones in which
one circuit is converted to an electronic 1-2 / 2J. The glider used for the handset in such a
telephone must be composed of a microphone unit and an amplifier, and the 0 microphone unit
and platform are unitized in consideration of use for a kite i It is more convenient to do it.
Moreover, it is desirable to use a fist that can be incorporated without changing the transmission
/ reception tk of the one used conventionally. The purpose of the present invention is to provide
four units of the spreader and the unitized feeder by using such a microphone unit ◆ According
to the present invention, it is provided on the swing plate side of the microphone unit main body

figure out the '-4 business of Jin in detail. The microphone 1 is integrated as a whole from the
perspective of the assembly 21 of the internal structure from the diagram of FIG. 1 in which the
internal structure is incorporated. The microphone unit body 2, the backing 3, the circuit base for

dimensions a little. The connection between the terminal 8 of the microphone unit body 2 and
the circuit board 4 and the connection terminal 18 for external connection and the circuit board
4 may be made by connecting a lead wire 19 or the like before caulking the front cover 6. In
addition, since it is easy to match the outline determined by the rear cover 5 and the front cover
6 and the conventional transmitter, it can be used as it is for the conventional handset. According
to the present invention, as described above, one microphone unit and an amplifier can be
unitized to provide a simple transmitter with few components.
