摘要：A transmitter-receiver comprises a transmitter, a transmitter circuit, a receivercircuit, a receiver, a jack, and a switch. The transmitter circuit converts an aural signal to atransmit signal and transmits the transmit signal. The receiver circuit extracts an auralsignal from a receive signal. The jack is adapted to be connected with a plug of anexternal transmitter-receiver. The switch is on/off controlled dependent on whether ornot the jack of the external transmitter-receiver is connected with the plug. The switch,when the jack is not connected with the plug, supplies an aural signal from the

transmitter to the transmitter circuit and also supplies an aural signal from the receivercircuit selectively to the receiver. Further, the switch, when the jack is connected with theplug, supplies an aural signal from the external transmitter-receiver to the transmittercircuit through the plug and jack and also supplies an aural signal from the receiver circuitselectively to the external transmitter-receiver through the jack and plug.
