Water proof type moving-iron receiverTechnical field
The present invention relates to moving-iron receiver technical field, be specifically related to a kind of water proof type moving-iron receiver.
Background technology
In prior art, the vibration that the principle of acoustic is because in air is delivered to vibration by external ear auditory meatusTympanum, by the auditory nerve of the vibratory drive people that tympanum is formed, the thus vibration of perception sound.But existing receiver is subject toAmbient temperature, the environmental effect such as humidity causes, and tonequality is unintelligible, and noise is big, and in terms of electroacoustic conversion ratio, conversion efficiency is low,Causing power consumption big, flying power is not enough.
Summary of the invention
Non-watertight for above-mentioned existing receiver, the problems such as tonequality is unintelligible, the technical problem to be solved isA kind of water proof type moving-iron receiver is provided.
For solving above-mentioned technical problem, the technical scheme that the present invention takes is: a kind of water proof type moving-iron receiver, including being subject toWords device body, sound mouth and coil, it is characterised in that: being receiver's body below described sound mouth, described receiver's body is provided withThrough hole, is vibrating diaphragm below described through hole, and described vibrating diaphragm is fixed on vibrating diaphragm support, and described vibrating diaphragm support is fixed on receiver's bodyOn, described vibrating diaphragm is provided with protecting film, and this internal blade of a sword ferrum that is provided with of described receiver, described blade of a sword ferrum is provided with contiguous block, described companyConnecing block to be connected with reed, this internal coil that is provided with of described receiver, described reed passes coil, and described reed is arranged over firstPermanent magnet, described first permanent magnet is fixed on blade of a sword ferrum, is provided with the second permanent magnet below described reed, and described second permanent magnet is fixedOn receiver's body, described reed being connected with vibration-sensing rod, described vibration-sensing rod is connected with vibrating diaphragm, below described receiver's bodyBeing provided with pad, described pad is connected with coil by wire.
The preferred version of such scheme is: be provided with groove between described vibrating diaphragm and vibrating diaphragm support, and the both sides of described groove setThere is outlet.
The preferred version of such scheme is: described vibrating diaphragm thickness is 0.015-0.03mm, and material is almag.
The preferred version of such scheme is: described sound mouth and through hole are at same position.
The preferred version of such scheme is: described protecting film is TPU material.
The preferred version of such scheme is: the material of described contiguous block is natural rubber.
Provide the benefit that: water proof type moving-iron receiver of the present invention, shake including receiver's body, permanent magnet, coil, biographyBar, reed, blade of a sword ferrum and vibrating diaphragm, when there being electric current to pass through on coil, the reed in coil produces magnetic, sets above and below reedHaving Magnet, during therefore reed is in magnetic field, owing to the effect reed favour of magnetic force produces vibration, reed is connected with vibration-sensing rod, and biography is shakenBar is connected with vibrating diaphragm, causes diaphragm oscillations, from hearing sound, is provided with groove between vibrating diaphragm and vibrating diaphragm support, and groove both sides set outThe mouth of a river, during the water inlet of sound mouth, water can be flowed in groove, be discharged by outlet, is affected by water and produces miscellaneous when reducing diaphragm oscillationsSound, is provided with natural rubber between reed and blade of a sword ferrum, is possible to prevent receiver's body to vibrate, and produces noise, and this receiver can not onlyEnough the most waterproof, the features such as dynamic ferrum technology has reliable and stable, extremely low distortion, energy saving, enclosed construction, not by external environment because ofElement interference, clear sound will not be lost one's head without noise, noiselessness, long-time use.
