ロール回路。 In a personal computer that uses a television receiver as a monitor, a switch circuit is provided between the audio output circuit of the personal computer and the speaker, and continuity is established by applying a control voltage from the power supply to the switch circuit via a resistor. On the other hand, when a connector for supplying a signal from the personal computer to the television receiver is connected, a control voltage to the switch circuit is supplied to the television receiver via the connector. A voice control circuit characterized in that it is grounded on the side and makes the switch circuit non-conductive.
