The reason why the voice signal extraction unit 28 is coupled to the speaker stage (SPK) line is that the speaker line is not only the voice signal of the other party, but the voice signal generated from the talker unit (microphone) of the handset 30 is the main body of the telephone. This is because it is amplified through the (10) and is delivered to the handset (speaker) of the handset 30 again to the side tone. Therefore, when the voice signal extraction unit 28 is coupled to the speaker stage, all call sounds between the talker and the receiver can be extracted.

Referring to the operation of the call-tone extraction coupler 20 having the circuit configuration as described above in detail, the first RJ connector 22 is coupled to the RJ connector connecting port of the telephone main body 10 and the handset 30 of the cord end When a telephone call is made while the RJ connector is connected to the first RJ connector connecting port 24, the call sound of each talker through the speaker line (SPK) line is transferred to the secondary side through the transformer T1 and is smoothed out by the smoothing circuit. After the smoothing process is output to the external recording device through the ear jack connection port (26). Therefore, the user can record a voice call transmitted through the ear jack connection port 26 to record a recording application on a recording medium (HDD) by running a separate dedicated application program installed in the personal computer 50.

On the other hand, if you look at the type of telephone currently on the market, the telephone line connecting the telephone body 10 and the handset 30 by manufacturer is not standardized. Therefore, there is a need for a coupler 20 for extracting a call sound having a switching circuit for simply selecting two speaker lines among telephone lines regardless of the phone manufacturer. As shown in FIG. 5, a coupler 20 for extracting a call sound having a switching circuit incorporated therein is illustrated.
