受信機。[Claims for Utility Model Registration] (1) An intermediate frequency amplification and detection circuit that amplifies and detects an intermediate frequency signal from an input stage circuit, and a signal passing means arranged on a detection output line of this intermediate frequency amplification and detection circuit. and a control means for controlling the signal passing band of the signal passing means based on the operation of the volume adjusting means, and when the volume is set to a high level by the volume adjusting means, the control means controls the signal passing band of the signal passing means based on the operation of the volume adjusting means. The pass band of the signal passing means is made narrow, thereby restricting the passage of low-frequency signal components, and when the volume is set to a medium level or lower by the volume adjusting means, the control means allows the signal to pass. A radio receiver characterized in that the pass band of the means is wide band, thereby allowing passage of low frequency signal components. (2) A utility model registration claim characterized in that the signal passing means is a capacitor placed on the detection output line, and the control means is a series circuit consisting of a capacitor and a semiconductor switching element connected in parallel with the capacitor. Radio receivers listed in scope (1).
