徴とするラジオ受信機。The configuration is such that a low frequency signal is supplied from the low frequency amplification stage to a first terminal of an earphone (or headphone) jack via a first high frequency signal blocking coil, and a second terminal of the jack
A second high-frequency signal blocking coil is provided between the terminal of the jack and the ground, and the high-frequency reception input signal induced in the lead wire of the earphone (or headphone) is blocked from the low-frequency signal from the first or second terminal of the jack. The radio receiver is configured to apply a high frequency signal to the high frequency input stage through a capacitor, and is provided with a switch that operates in conjunction with insertion and removal of an earphone (or headphone) plug into the jack, and the switch operates to connect the earphone (or headphone) plug to and removal from the jack. When the earphone (or headphone) plug is inserted into the jack, the low frequency amplification stage and the speaker are cut off, and when the earphone (or headphone) plug is not inserted into the jack, the low frequency from the low frequency amplification stage is cut off. A radio receiver characterized in that the radio receiver is configured to supply a signal to the speaker without passing through the first high-frequency signal blocking coil.
