Abstract

PURPOSE:To reduce useless power consumption and to extend the service life of a battery by intermitting a power supply of a low frequency part depending on the strength of an electric field and intermitting the power supply of the low frequency part depending on the presence of sound information. CONSTITUTION:A signal received by a receiving section 1 is applied to a squelch section 2, a sound information detecting section 8 and a pre-sound-amplifier section 5. Further, a power supply is applied to the detecting section 8 when the strength of electric field is large and the power supply is interrupted when the strength of electric field is small. When the power supply is applied to the detection 8, the detection section 8 detects the presence of sound information and its output drives a switch 9. The switch 9 has a function intermitting the power supply to the sound information amplifier section 5 and a power amplifier section 6, supplies the power supply to the amplifier section 6 when a modulation has and interrupts the power supply to the amplifier sections 5 and 6 when no information exists.
