TH27717B - Methods and devices for controlling the volume of the telephone radio. - Google Patents

Abstract

Telephone radio system with adjustable volume control with microphone, speaker, sender And the microphone volume control will generate sound. The output power reacts to the sound and the speaker generates a sound in response to the electrical signal. The sender input responds to the microphone. And transmitting communications with radio and telephone To someone far away And receive telephone radio communications from people far away to generate electrical audio input Adjusting the volume control Will respond to the signal Electrical sound output And select the sound amplitude generated by the speaker. Therefore, the amplitude of the sound generated by the speaker increases as the amplitude of the sound received by the microphone increases. And decrease when the amplitude of the sound received by the microphone decreases
