MULTI-FUNCTION DEVICE FOR CONTROLLING VOICE SIGNALS

摘要

PURPOSE: A multi-function device for controlling voice signals is provided to perform voice amplification and control simultaneously for voice signals received from media of mutually different sound producing apparatuses, so as to output and control the voice signals at the same time through one output unit. CONSTITUTION: A voice signal controller(201) detects electric voice signals inputted from mutually different media, to perform signal processing for the electric voice signals at the same time and independently with each other, for low frequency amplification. A first interface(202) connects the voice signal controller(201), the user interface part(30) and a second sound reproducing apparatus(40). A user interface part(30) enables a user to control the voice signal controller(201). In the user interface part(30), a microphone(302) and an ear phone(302) are included. An alarm switch(303) generates emergency signals to a speaker(106) of a first sound reproducing apparatus or the second sound reproducing apparatus(40) on emergency. A secret call switch(304) is for secret speech when the second sound reproducing apparatus(40) is a communication apparatus. And a multiple receiving/search switch/control(305) receives/searches/controls the voice signals from the media for amplification and reproduction.
