Speaker 510 installed inside the head portion accommodated in the ear of the user, the on-off switch 530 is installed so as to protrude to the outside of the main body of the transceiver 500 for turning on and off the communication unit 500 The microphone 520 installed inside the lower part, the transmission and reception code inlet 560 of the tail portion, the speaker 510, the on-off switch 530, the microphone 520 and the transmission and reception code 410 are electrically disposed It consists of a PCB 540 to make.

The transceiver 500 is configured to isolate the position of the microphone 520 in a structure for maximally preventing a howling phenomenon with the microphone 520 adjacent to the speaker 510.

Reference numeral 482 in the above description is a step formed in the receiving base plate 430.

The operation of the additional transceiver of the portable communication device of the present invention having the above configuration will be described.

When the user does not use the additional transceiver of the present invention, the portable communication apparatus 100 is connected to the portable communication apparatus 100 by the connection cord 270, and is operated by the spring 440 of the code receiving box 200. The transmission / reception code 410 is all wound around the code accommodation port 400.

When the user wants to use the additional transmission and reception apparatus of the present invention, when the transmission and reception device 500 is pulled, the cord receiving device 400 rotates the spring fixing protrusion 220 while the transmission and reception code 410 receives the code. The transmission / reception code extraction unit 230 of 200 is drawn out.

At this time, the spring 440 of the cord receptacle 400 is dried inward to generate a pulling force.

When the transmission / reception code 410 releases the force pulled by the user in a state of exiting the code accommodation device 400 by an appropriate length, the code accommodation device is provided in the stopper 210 installed in the base plate 260 as shown in FIG. 8B.
