The bone conduction sensor consists of an electromagnetic assembly and a vibration assembly from the bottom up; the electromagnetic assembly comprises a yoke iron, a magnetic polearranged at the center of the yoke ion, a coil sheathed on the magnetic pole, projections arranged on left end and right end of the yoke ion outside the coil, and a disk-shaped magnet arranged abovethe coil and the projections, and an opening is provided at the center of the magnet for the magnetic pole to pass through; and the vibration assembly comprises a yoke board and a vibrating plate, thevibrating plate is provide with an opening at the center, wing plates at front end and rear end bend downwards and then are connected to the front end and the rear end, and the yoke board is arranged in the opening at the center of the vibrating plate and arranged above the magnetic pole, and a gap is provided between the yoke board and the magnetic pole. The bone conduction sensor is characteriz ed by simple structure, high efficiency, small size, convenient manufacture, high qualification rate and wide frequency response range.
Description
Technical field
The present invention relates to bone conduction technology, particularly relate to a kind of technology of bone conduction audio-frequency device.
Background technology
Existing bone-conduction device is shown in Figure 1, and magnetic pole 42 is located at yoke 41 central authorities, and coil 44 is sleeved on magnetic pole 42, and two magnet 45 are arranged on coil 44 outsides, and yoke plate 46 is arranged on magnetic pole 42 tops, and and magnetic pole 42 between be provided with gap.This design is because the coupling area between two magnet and yoke plate is less, and and the magnetic circuit between magnetic pole is longer, for overcoming larger magnetic resistance, must increase the volume of magnet, and two magnet are arranged on coil outside, thereby make bone-conduction device volume become very large, and conduction efficiency is not high, so cannot be when guaranteeing conduction efficiency, by bone-conduction device miniaturization, therefore this bone-conduction device cannot be applied in a lot of small-sized electronic products.In addition, this design adopts two magnet, and during assembling, magnet direction also easily goes wrong.
Summary of the invention
For the defect existing in above-mentioned prior art, technical problem to be solved by this invention be to provide a kind of have simple in structure, efficiency is high, volume is little, it is easy to manufacture, bone conduction sensor that qualification rate is high, frequency response range is wide.
In order to solve the problems of the technologies described above, a kind of bone conduction sensor provided by the present invention, is followed successively by electromagnetic assembly, vibration component from bottom to top; It is characterized in that, electromagnetic assembly comprises yoke, be located at the yoke central authorities magnetic pole of (upwards), be sleeved on coil outside magnetic pole, be located at being positioned at protuberance outside coil, being located at the magnet of coil and protuberance top of two ends, yoke left and right (upwards), magnetic blow out centre is provided with perforate, and magnetic pole is through described perforate; Vibration component comprises yoke plate, vibrating reed, and vibrating reed center is provided with opening, and the wing plate of vibrating reed rear and front end is connected on the rear and front end of yoke after bending downwards; Be located at yoke plate in vibrating reed central opening and be positioned at magnetic pole top, and and magnetic pole between be provided with gap.
Further, described magnetic pole and its through the perforate of magnetic blow out centre be provided with gap.
Further, described yoke plate is provided with at least one screwed hole for whole bone conduction sensor is installed.
Further, described yoke profile and inside are all rounded.
Further, described yoke profile is rectangular, inner ovalize.
Bone conduction sensor provided by the invention, owing to magnet being arranged on to coil top, shortened the magnetic circuit between magnet and magnetic pole, also improved the coupling area between magnet and yoke plate, magnetic resistance is significantly declined, thereby in equal output situation, can reduce coil turn, thereby dwindle diameter and the height of coil, in height for magnet is abdicated space, make magnet take certain altitude, and do not take more area, thereby in the situation that remaining unchanged, power output dwindled the volume of bone-conduction device, and simple in structure, manufacture easy, make the qualification rate of product high, owing to having improved coupling area, make yoke plate and vibrating reed stressed evenly, reduced the hesitation of vibrating reed, the frequency response range of bone conduction sensor is widened, definition is improved, in addition, owing to only having used a magnet in bone conduction sensor, so while installing without adjusting magnet direction, install very simple.
Bone conduction sensor provided by the invention, both can be used as speaker operation, also can be used as pick-up work.
