1 is a state in which the jack of the magnetic conversion output device of the cassette type is inserted into the earphone is equipped with a jack socket

2 is the overall configuration of the design

Figure 3 is another embodiment

* Description of the signs in the drawings

1: socket for plugging jack 2: magnetic converter

3: Microphone 4: Cellphone Connection Earphone Jack

Referring to the present invention in detail based on the accompanying drawings as follows.

1 is connected to the jack socket (1) to the voice output unit 5 of the earphone and the jack (7) of the cassette-type magnetic conversion output device is connected to the socket when the jack (7) is inserted into the received earphone The output is cut off to the microspeaker 5 which outputs sound, and the output is transmitted to the magnetic converter 2. This is similar to the principle that when the earphone is inserted in the audio, the speaker does not sound and only the earphone is output.
