A wireless interphone of an antigas mask is composed of a body, a pickup and an earplug receiver. The body and the pickup are installed at the front end of the antigas mask in a partitioned manner, and a speech transmitting socket is connected on the pickup; the body is composed of a shell, a loudspeaker, a battery, a circuit board and an antenna, the loudspeaker, the battery and the circuit board are arranged in the shell, and the antenna is arranged outside the shell; a speech transmitting plug and a speech receiving socket are arranged outside the shell, the speech transmitting plug is connected with the speech transmitting socket, and the speech receiving plug is connected with the earplug receiver; a DSP (digital signal processor), an audio coder and decoder unit, a radio frequency transceiver circuit, a radio frequency front-end amplifier and an audio power amplifier are arranged on the circuit board; an analog voice signal input terminal of the audio coder and decoder unit is connected with the speech transmitting plug, first and second analog voice signal output terminals are respectively connected with the input end of the audio power amplifier and the speech receiving socket, and the output end of the audio power amplifier is connected with the loudspeaker; an exhaling passage on the lower portion of the shell corresponds to an exhalation valve of the antigas mask. By the arrangement, wireless communication of multiple people can be realized, and a voice-amplifying communication function is achieved.
Description
technical field [0001] The invention belongs to the field of electroacoustic and communication technologies, and in particular relates to a wireless communicator for a gas mask. Background technique [0002] At present, due to factors such as the structure, material, and airtight cavity of the gas mask, the voice communication of the personnel is seriously affected, and it is difficult to communicate between the personnel. Usually, the voice amplification method is used to compensate and amplify the voice to improve the voice sound pressure level and language. clarity. However, this method has a limited calling distance, which is about 50 meters in a quiet environment. If the distance is long, especially in a noisy environment, it cannot meet the needs of use. Contents of the invention [0003] The technical problem solved by the present invention is to provide a gas mask wireless communicator, which is integrated with the gas mask, combines electroacoustic communication...
