Title: Conference telephone system
Inventor: MARUYAMA TADASUKE
IPC: H04M9/08
Filed: 1988-01-25
Abstract: PURPOSE:To remove the influence of the non-linear distortion of a loudspeaker generated since the loudspeaker is removed from a conventional echo path by supplying the output signal of a microphone for sound-receiving to a dummy echo path, and supplying a receiving input signal to the loudspeaker and a double-talk detecting circuit. CONSTITUTION:The receiving input signal introduced from a receiving signal input terminal 7 is supplied to a loudspeaker 8, and supplied to a double-talking detecting circuit 5 in the same way. A sound wave made loud inside a room is sound-received by a microphone 9 for sound-receiving, and the output signal is conducted to a dummy echo path 3. On the other hand, the sound wave made loud is sound-received by a microphone 1 for transmitting, and the output signal is conducted as the input signal of one side of a subtracting circuit 4 or as the input signal of the double-talking detecting circuit 5. The double-talking detecting circuit 5 executes a level comparison between the receiving input signal and a transmitting input signal, and when the level of the receiving input signal is larger than the level of the transmitting input signal, a control is executed so as to correct the dummy echo path characteristic of the dummy echo path 3.
