Underwater wireless voice electromagnetic communication simulating system

Abstract

The utility model relates to an underwater wireless voice electromagnetic communication simulating system and relates to a realizing method of an underwater wireless voice electromagnetic communication system. Voice signals of the system are input by a microphone (1), the rear end of the microphone (1) is connected with a pre-posed low noise amplifier circuit (2), the rear end of the pre-posed low noise amplifier circuit (2) is connected into a band-pass filter (3), the band-pass filter (3) is connected with a power amplifier (4), and finally the signals are sent to an antenna (C) by a matching network (5); a signal receiving part (B) firstly passes through a primary difference amplifying circuit (9), and then is connected with a high-pass filter (10), a secondary amplifying circuit (11), a low-pass filter (12), an automatic gain control circuit (13) and an earphone amplifying circuit (14), and finally the voice signals are restored; and real time voice can be heard from an earphone (15). The system is good in performance, can realize short-distance real time communication function with low noise under water, and adopts a half-duplex communication manner.
