Abstract
A radio communication apparatus includes a transceiver circuit, an internal speaker, an internal microphone, an external connection terminal, a connection detection circuit, a drive setting circuit, and a disconnection detection circuit. The transceiver circuit transmits and receives a transmission audio signal and a reception audio signal. The connection detection circuit detects a connection between the external speaker-microphone and the external connection terminal. The drive setting circuit drives the internal speaker and the internal microphone when the connection is not detected, and drives the external speaker-microphone when the connection is detected. The disconnection detection circuit detects a disconnection in an audio signal line for the external speaker. Further, when the disconnection is detected, the drive setting circuit makes the internal speaker output a sound represented by a reception audio signal.
