Summary of the invention
The technical problem that the utility model solves: design a kind of gas mask electroacoustical transducer, combat duty is performed, when carrying out manoeuvre training and deal with contingencies chemical defence personnel, combine closely with breathing mask, the decay to voice sound pressure level and speech articulation that effective compensation breathing mask cavity and call film cause, the speech exchange ability of the personnel of wearing can be significantly improved, have and link up the features such as convenient, voice distortion is little, speech range is far away.
Technical solution of the present utility model: a kind of gas mask electroacoustical transducer, described communication is made up of main body, pick-up, described main body spiral-lock is in the outside of breathing mask front end, and pick-up is arranged on the inner side of breathing mask front end, and on pick-up, words socket is sent in connection; Described main body is made up of housing and the loud speaker be arranged in housing, battery, circuit board, and loud speaker is positioned at housing front, battery is positioned at housing rear; The rear end face of described housing has and send words plug, and make to send words plug to talk about socket and be connected with sending; Described circuit board is provided with signal processor, audio-frequency power amplifier, and described signal processor input is talked about plug and is connected with sending, and output is connected with audio-frequency power amplifier input, and audio-frequency power amplifier exports termination loud speaker; The bottom of described housing has exhalation path, and the entrance point of exhalation path exports corresponding with the outlet valve of breathing mask front end, and the port of export of exhalation path is positioned at the below of housing.
Described pick-up is by water proof ring, electret cover, electret lid, electret and be configured to, described electret is fixed in electret cover, water proof ring, electret lid are bonded in electret and overlap upper and lower both sides, electret cover loads the central authorities of support, support installing in the inner side of breathing mask front end, described in send words socket be connected with electret by shielding conductor.
The outside of described housing has self-lock switch and charging socket.
The advantage that the utility model compared with prior art has and effect:
1, the utility model pick-up and communication main body adopt split-type structural, make pick-up and loud speaker not on same cavity, by breathing mask cavity pickup district and amplifying separated from, to the suppression self-excitation effect of uttering long and high-pitched sounds significantly, do not affect the air-tightness of mask self simultaneously.
2, the utility model is combined with breathing mask and can obviously solves the problems such as the voice distortion caused when wearing a gas mask merely is large, speech range is short, personnel transfer is difficult, meet the Special use environment for use requirement that chemical defence personnel perform combat duty, carry out manoeuvre training and deal with contingencies, through repeatedly with user's joint-trial, reflection technology is excellent, practical.
3, the utility model adopts hermetically-sealed construction, can rainproof, dust-proof, Defend salt fog, and possesses good anti-electromagnetic interference capability, good environmental adaptability.

Embodiment
1,2,3,4,5,6 a kind of embodiment of the present utility model is described by reference to the accompanying drawings.
A kind of gas mask electroacoustical transducer, be made up of main body 1, pick-up 2, described main body 1 spiral-lock is in the outside of breathing mask 5 front end, and pick-up 2 is arranged on the inner side of breathing mask 5 front end, and on pick-up 2, words socket 3 is sent in connection; Described main body 1 is made up of housing 4 and the loud speaker 6 be arranged in housing 4, battery 7, circuit board 8, and loud speaker 6 is positioned at housing 4 front, battery 7 is positioned at housing 4 rear; The rear end face of described housing 4 has and send words plug 9, and make to send words plug 9 to talk about socket 3 and be connected with sending; Described circuit board 8 is provided with signal processor, audio-frequency power amplifier, and described signal processor input is talked about plug 9 and is connected with sending, and output is connected with audio-frequency power amplifier input, and audio-frequency power amplifier exports termination loud speaker 6; The bottom of described housing 4 has exhalation path 11, and the entrance point of exhalation path 11 exports corresponding with the outlet valve 12 of breathing mask 5 front end, and the port of export of exhalation path 11 is positioned at the below of housing 4.The outside of described housing 4 has self-lock switch 10 and charging socket 13.
Described pick-up 2 overlaps 2-2, electret lid 2-3, electret 2-4 and support 2-5 by water proof ring 2-1, electret and forms, described electret 2-4 is fixed in electret cover 2-2, water proof ring 2-1, electret lid 2-3 are bonded in the electret cover upper and lower both sides of 2-2, electret cover 2-2 loads the central authorities of support 2-5, support 2-5 is arranged on the inner side of breathing mask 5 front end, described in send words socket 3 be connected with electret 2-4 by shielding conductor.
During use, pick-up is stuck in inner corresponding hole, breathing mask front end by four short columns on support, communication main body snaps fitted to breathing mask front end by groove, ensure after wearing a gas mask that mask rubber part is adjacent to face, press self-lock switch, user's speech just can transmit call-information, and the exhalation path on the outlet valve of the gas of simultaneously breathing out on breathing mask (expiration is opened, and closes during air-breathing), housing flows to extraneous; When not using, closing self-lock switch, unload pick-up and communication main body from breathing mask, loading dedicated box in order to preserving.
