Abstract

PURPOSE:To reproduce received-audio signals at a basis-audio-volume level set by audio-volume adjusting means by equipping the audio-volume adjusting means adjusting audio-volume signals obtaining through switching means. CONSTITUTION:Normally, when the selection switch 9 is selected to the audio circuit 6, reception audio signal is obtained from the circuit 6, this is fed to the audio adjusting set 10 via the switch 9, and after it is adjusted to the audio volume level predetermined, it is fed to the speaker 7 and audio sound is broadcast. When a finger is touched on the touch plate 14, the gate circuit 13 is opened while touching, and the clock pulse produced from the clock pulse generator 12 is fed to the counter 11 sequentially via the circuit 13. The output is sequentially changed when the clock pulse is fed to the counter 11 and thus, the set level of the adjustor 10 is changed over in step. Accordingly, the listener detouches the finger touch plate 14 at the desired audio volume, while listening to the audio volume broadcast from the speaker 7, then desired audio volume can be obtained.
