The active area of pole and yoke plate is compressed, and working efficiency is not high, while two magnet are mounted on two sides and also limit cutting for magnetic pole
The number of turns of area and coil further affects working efficiency, and frequency response is also uneven.
Summary of the invention
For above-mentioned defect existing in the prior art, technical problem to be solved by the invention is to provide a kind of work effects
Rate is high, and the double-round formula bone conduction sensor that processing efficiency is high.
In order to solve the above-mentioned technical problem, a kind of double-round formula bone conduction sensor provided by the present invention, including yoke, vibration
Movable plate, yoke plate, it is characterised in that:
The upper side of the yoke is equipped with electromagnetic assembly, and the electromagnetic assembly includes a magnet and two magnetic poles, wherein
Magnet be mounted in the middle part of yoke, two magnetic poles are symmetrically laid in the left and right sides of magnet, are respectively equipped with one on two magnetic poles
Coil；
The oscillating plate is mounted on yoke, and centre bore up and down is offered on oscillating plate, which is located at electricity
The surface of magnetic assembly；
The yoke plate is mounted on the center hole portion of oscillating plate, and is located at the surface of electromagnetic assembly, yoke plate and electromagnetic assembly
Between have gap.
Further, the yoke plate connects the upper end of magnet by the magnetic liquid of soft magnetism.
Further, the front center of the yoke plate has protruding portion outstanding forward, have in the middle part of the rear end of yoke plate to
Protruding portion outstanding afterwards, the rear and front end protruding portion of yoke plate are respectively rested on the left and right of oscillating plate centre bore along upper.
Double-round formula bone conduction sensor provided by the invention is realized conduction using double magnetic poles and twin coil mode, can be made
Magnetic pole section is long-pending and coil total number of turns increases, and the increase of magnetic pole section product can not only greatly reduce magnetic circuit reluctance, but also can further subtract
Small magnet volume, while magnetic circuit is less prone to magnetic saturation, fully ensures that sensing quality, has the characteristics that work efficiency is high, and
Due to having only used a magnet, when assembling, does not need adjustment magnet direction, reduces the probability of assembling error, has processing life
High-efficient feature is produced, and only also the magnetic line of force can be made efficiently to concentrate with a magnet, so that magnet volume, which is much smaller than, uses two
The traditional bone conductors sensor of a magnet saves more spaces for magnetic pole and coil.
