Abstract

PURPOSE:To ensure the smooth talking for the sound volume adjustor for the speaker of the TV or the like through the automatic reduction of the speaker's sound volume by picking up the receiver of the telephone and via the signal of the transmitter provided with contact to the telephone under talking. CONSTITUTION:The call is detected by the originating part under talking through telephone 5 and then converted into the prescribed signals to be transmitted. Receiver 6 connected into the speaker circuit of speaker 7 of the TV or the like senses the signals transmitted from transmission part 4. During this time, control part 8 gives the reduction to the sound volume of speaker 9. The sound is reduced automatically under talking through telephone 5, thus ensuring the smooth talking.
