Abstract

The invention discloses an underwater voice transceiver. The underwater voice transceiver comprises an underwater shell and a circuit system. The circuit system comprises an underwater voice pickup, an underwater loudspeaker, an underwater sound transducer, an underwater voice signal processing circuit, an underwater sound signal processing circuit, an underwater master control CPU, an underwater power supply management circuit and an underwater PTT switch. Different triggering signals are sent to the underwater master control CPU; when the underwater PTT switch is switched off, the underwater master control CPU controls the underwater sound signal processing circuit to work; the working mode of the underwater voice transceiver is a receiving mode; when the PTT switch is switched on, the underwater master control CPU controls the underwater voice signal processing circuit to work; and the working mode of the underwater voice transceiver is a transmitting mode. According to the transceiver, the circuit format is simplified, the circuit power consumption is reduced, and the communication confidentiality is effectively improved.

Description

technical field [0001] The invention relates to the field of underwater voice real-time transmission, in particular to an underwater voice transceiver, a water voice transceiver and an underwater acoustic intercom system. Background technique [0002] In underwater operations such as underwater rescue and salvage, diving adventure photography, etc., communication between diving operators and between divers and land commanders is often required in order to coordinate and cooperate with each other to carry out operations. Only acoustic signals in water can effectively transmit long distances, so diving operators usually use underwater acoustic intercom systems based on underwater acoustic communication technology to communicate underwater and above water. There are few existing underwater acoustic intercom systems on the market. These existing underwater acoustic intercom systems are large in size, high in power consumption, and not easy to carry and install. [0003] Conside...
