Title: Hand free talking set
Inventor: YAJIMA MASAHARU
IPC: H04M1/60
Filed: 1985-11-01
Abstract: PURPOSE:To listen to an interruption request of opposite party without causing howling and intermission of transmission by attenuating a reception signal within an audible level without interrupting the signal even at the talking state and setting the setting time for reception/transmission independently. CONSTITUTION:A reception and a transmission signal level are detected by a reception signal level detection circuit 1 and a transmission signal level detection circuit 4 respectively and a transmission and a reception switch 6, 7 are controlled via a reception comparator 2, a transmission comparator 5 and a control section 3. When the transmission level is less than the 1st setting value or below and the reception level reaches the 2nd setting value or over, the reception state is set and when the reception level is the 2nd setting value or below and the transmission level reaches the 1st setting value or over, the transmission state is set independently of the reception and transmission, they are switched after a set time elapses to prevent howling. On the other hand, an attenuator 8 is connected to the switch 7 and the interruption request of the opposite party is listened to without intermission of the transmission by reception at the transmission state.
