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 referring to shown in Figure 1, and magnetic pole 42 is located at yoke 41 central authorities, and coil 44 is sleeved on the magnetic pole 42, and two magnet 45 are installed in coil 44 outsides, and yoke plate 46 is installed in magnetic pole 42 tops, and and magnetic pole 42 between be provided with the gap.This design is owing to the coupling area between two magnet and the yoke plate is less, and and the magnetic circuit between the magnetic pole is longer, for overcoming bigger magnetic resistance, must increase the volume of magnet, and two magnet are installed in the coil outside, thereby make the bone-conduction device volume become very big, and conduction efficiency is not high, so can't be when guaranteeing conduction efficiency, with the bone-conduction device miniaturization, therefore this bone-conduction device can't be used in a lot of small-sized electronic products.In addition, two magnet are adopted in this design, and the magnet direction also goes wrong easily during assembling.
Summary of the invention
At the defective that exists in the above-mentioned prior art, technical problem to be solved by this invention provides a kind of bone conduction sensor simple in structure, that efficient is high, volume is little, manufacturing is easy, qualification rate is high, frequency response range is wide that has.
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 magnetic pole of yoke central authorities (making progress), be sleeved on the outer coil of magnetic pole, be located at being positioned at the outer protuberance of coil, being located at the magnet above coil and the protuberance of two ends, the yoke left and right sides (make progress), magnetic blow out centre is provided with perforate, and magnetic pole passes described perforate; Vibration component comprises yoke plate, vibrating reed, and the 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 the bending downwards; Be located at yoke plate in the vibrating reed central opening and be positioned at the magnetic pole top, and and magnetic pole between be provided with the gap.
Further, be provided with the gap between the perforate of described magnetic pole and its magnetic blow out centre that passes.
Further, described yoke plate is provided with at least one screwed hole that is used to install whole bone conduction sensor.
Further, described yoke profile and inside are all rounded.
Further, described yoke profile is rectangular, inner ovalize.
Bone conduction sensor provided by the invention, because magnet is installed in the coil top, shortened the magnetic circuit between magnet and the magnetic pole, also improved the coupling area between magnet and the yoke plate, make magnetic resistance significantly descend, thereby under equal output situation, can reduce coil turn, thereby dwindle the diameter and the height of coil, in height abdicate the space for magnet, make magnet take certain altitude, and do not take more area, thus under the situation that power output remains unchanged, dwindled the volume of bone-conduction device, and simple in structure, make easyly, make the qualification rate height of product; Owing to 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 used a magnet in the bone conduction sensor,, install very simple so need not to adjust the magnet direction when installing.
Bone conduction sensor provided by the invention both can be used as speaker operation, also can be used as pick-up work.
