The invention relates to an anti-noise industrial broadcast talkback station that includes a host machine and a microphone. At the front face of the host machine panel are set with a channel selection switch and a microphone hanging-seat on which is fitted with a magnetic attracting hang-up switch. At the back face of the host machine are set with sealing material, channel selection circuit board and signal amplification coupling circuit board. At the base of the host machine are set with power supply board, transformer and line conduct bank. A push button is set on the microphone handle. The microphone is low in sensitivity and is fitted with a protective cover having bevel face with stripe-like sound-transmission grating. The earphone is fitted with a protective cover in which is provided with a high-sensitivity loudspeaker. Between the peripheral of the interior of microphone and earphone is provided with a cotton sound-absorption layer. Advantage: high production efficiency and security.
Description
technical field [0001] The present invention relates to industrial communication equipment, relates to an industrial radio talk-to-talk station, in particular to an anti-noise industrial radio talk-to-talk station. Background technique [0002] As we all know, the use of industrial communication equipment is completely different from that of ordinary communication equipment. Not only must the dustproof and waterproof issues be considered, but more importantly, it must have the function of anti-noise. [0003] However, the existing industrial communication equipment can only solve the protection problem of the industrial site in general, that is, it only considers the problem of dustproof and waterproof, but cannot effectively resist the interference of environmental noise to the communication system. At present, in the prior art, the dynamic microphone is simply used as the input device of the on-site telephone station to solve the environmental noise, and this device is use...
