A demodulation part(123) demodulates a receiving signal of the radio broadcast receiver part. An amplification part(124) amplifies a signal of the demodulation part. A channel selection part(125) selects a radio broadcast channel by selecting a receiving frequency of the receiver part. A volume control part(127) controls a volume of the radio broadcast by controlling an output level of the amplification part. And a radio selection switch(128) selects an output of the amplification part and connects it to the speaker.
