Utility model content
For the defect existed in above-mentioned prior art, it is high that technical problem to be solved in the utility model is to provide a kind of operating efficiency, and two ring type bone conduction sensors that processing efficiency is high.
In order to solve the problems of the technologies described above, the two ring type bone conduction sensor of one provided by the utility model, comprises yoke, oscillating plate, yoke plate, it is characterized in that:
The upper side of described yoke is equipped with electromagnetic assembly, and described electromagnetic assembly comprises a magnet and two magnetic poles, and magnet is wherein arranged in the middle part of yoke, and two magnetic poles are respectively equipped with a coil in the left and right sides being laid in magnet of two magnetic pole symmetries;
Described oscillating plate is arranged on yoke, oscillating plate offers the centre bore of up/down perforation, and this centre bore is positioned at directly over electromagnetic assembly;
Described yoke plate is arranged on the centre bore portion of oscillating plate, and is positioned at directly over electromagnetic assembly, has gap between yoke plate and electromagnetic assembly.
Further, described yoke plate connects the upper end of magnet by the magnetic liquid of soft magnetism.
Further, the front center of described yoke plate has protuberance outstanding forward, and have rearwardly projecting protuberance in the middle part of the rear end of yoke plate, the rear and front end protuberance of yoke plate is shelved on the left and right of oscillating plate centre bore respectively along upper.
Two ring type bone conduction sensors that the utility model provides, two magnetic pole and twin coil mode is adopted to realize conduction, magnetic pole section sum coil total number of turns can be made to increase, the increase that magnetic pole section is amassed both can greatly reduce magnetic circuit reluctance, magnet volume can be reduced further again, not easily there is magnetic saturation in magnetic circuit simultaneously, abundant guarantee sensing quality, have the advantages that operating efficiency is high, and owing to only employing a magnet, do not need during assembling to adjust magnet direction, decrease the probability assembled and make mistakes, have the advantages that processing efficiency is high, and only the magnetic line of force also can be made efficiently to concentrate with a magnet, make magnet volume much smaller than the traditional bone conductors transducer of employing two magnet, for magnetic pole and coil save more spaces.
