Description
Technical field
The utility model relates to a kind of equipment that utilizes electromagnetic force to produce mechanical oscillation, particularly a kind of electromagnetic oscillation device.
Background technology
The electromagnetic vibrator that the applicant applied in the past, it is gone back to system and is formed by vibrating reed, outstanding limit, basin frame, magnetic, the vibrating reed back side links to each other with voice coil loudspeaker voice coil, voice coil loudspeaker voice coil places magnetic to go back to system again, described vibrating reed and outstanding limit are integral, and link to each other with terminal plate on the basin frame after the voice coil loudspeaker voice coil lead connects by vibrating reed again.During manufacturing, the back side of vibrating reed and voice coil loudspeaker voice coil are gluedd joint, and the voice coil loudspeaker voice coil lead is connected with conductor wire by vibrating reed, the conductor wire other end links to each other with basin frame upper terminal sheet again.
Above-mentioned this incomplete structure the making of vibrating reed need not to use or use the glue of nonessential function, finish and use machinery equipment instead, this machinery equipment contains injection moulding, Supersonic, ultrasonic, hot melt etc., therefore can reduce uniformity and the stability that artificial error guarantees vibrating reed.Vibrating reed links to each other with the basin frame and has also broken the traditional handicraft of loudspeaker, mode ultrasonic with ultrasonic, that hot melt is connected has replaced glue, therefore it has overcome conventional vibrator because the drawback that vibrating reed and outstanding limit adopt adhering method to bring, improve the quality and the qualification rate of product, thereby reduced cost.
But above-mentioned electromagnetic vibrator is because vibrating reed and voice coil loudspeaker voice coil still adopt glue then, and because glue is generally polar substances, time has been grown back easy oxidation, owing to the oxidation of glue makes its rerum natura variation, phenomenon is peeled off in generation so cause then not firm, and because the artificial mode operation of the normal use of applying glue process, therefore processing procedure is complicated, resin added is difficult to grasp consistent, so can't ensure the weight uniformity and the stability of vibrating reed, also can't guarantee the quality of entire product, limit its scope of application.
Adopt the loudspeaker of above-mentioned vibrating reed and this connected mode of voice coil loudspeaker voice coil, when the power of loudspeaker was big, because vibration is fierce, regular meeting occurred peeling off and throws off and damage between vibrating reed and voice coil loudspeaker voice coil.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and a kind of electromagnetic oscillation device is provided, and makes that its performance is more stable, quality consistency good.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Electromagnetic oscillation device, involving vibrations sheet, outstanding limit, basin frame, voice coil loudspeaker voice coil, magnetic go back to system up and down, the described vibrating reed surface voice coil loudspeaker voice coil fixing hole that is uniformly distributed along the circumference, described voice coil loudspeaker voice coil has corresponding inserted sheet, and the inserted sheet of voice coil loudspeaker voice coil passes the voice coil loudspeaker voice coil fixing hole of vibrating reed and is fixed on the vibrating reed.
The lead of above-mentioned voice coil loudspeaker voice coil embeds in the groove at the vibrating reed back side, and the lead other end is fixed on down on the basin frame.
Above-mentioned vibrating reed, the basin frame is directly injection molded up and down.
Above-mentioned vibrating reed, outstanding limit and last basin frame are welded together with the embedding injection molding way.
This vibrator returns structure according to the magnetic of loudspeaker, and when the input sine wave signal was given vibrator, vibrator can up-down vibration.And give vibrator, the frequency of this signal when fixing sinusoidal wave signal of input just in time is the natural resonant frequency of vibrator when identical, only need provide very little some electric energy to vibrator, will allow vibrator produce high vibration about the peak swing.
For making above-mentioned electromagnetic oscillation device, adopt following steps:
(1), injects the vibrating reed and the last basin frame of the voice coil loudspeaker voice coil fixing hole of and voice coil loudspeaker voice coil inserted sheet correspondence position even along circumference;
(2), vibrating reed, last basin frame are put into the mould embedding of outstanding limit and penetrate into the vibrating reed sub-assembly;
(3), vibrating reed sub-assembly and following basin frame combine with ultrasonic, ultrasonic wave or melt process;
(4), the protruding inserted sheet of voice coil loudspeaker voice coil passes the voice coil loudspeaker voice coil fixing hole of vibrating reed, the inserted sheet reflexed of the voice coil loudspeaker voice coil projection of vibrating reed will be passed, make it tightly to fasten on vibrating reed, voice coil loudspeaker voice coil and vibrating reed are firmly fixed, and linked to each other with following basin frame upper terminal sheet again after the lead of voice coil loudspeaker voice coil being embedded in the groove at the voice coil loudspeaker voice coil back side;
(5), magnetic goes back to system and is fixed on down in the basin frame.
Compared with prior art, advantage of the present utility model is:
1, traditional structure all is that voice coil loudspeaker voice coil and vibrating reed is bonding with glue, but when input was high-power, the vibrating reed amplitude was bigger, is easy to occur the disengaging between voice coil loudspeaker voice coil and vibrating reed or bulging paper.The utility model is because being connected by special inserting mode between vibrating reed and voice coil loudspeaker voice coil, need not glue and finish with machinery equipment compacting, therefore can guarantee to fixedly secure between vibrating reed and voice coil loudspeaker voice coil, prevent glue and use the back to produce the then not firm phenomenon of peeling off for a long time because of oxidation.Also saved glue, directly influence the resonant frequency of vibrating reed owing to beat the many of glue with I haven't seen you for ages, and no matter be engine sizing or artificial gluing, the glue amount require very little in, all can bring error, so the utility model has overcome the drawback that its vibrating reed of original vibrator and voice coil loudspeaker voice coil employing adhering method bring, the quality and the qualification rate of product have been improved, make it technology simple, produce fast, boost productivity greatly, thereby reduced cost.
2, omit conducting strip, directly adjusted the weight of vibrating reed, thereby convenient the making, the intrinsic frequency of vibrator also can be adjusted more easily.
Because the electromagnetic oscillation device volume can adjust arbitrarily, vibration efficiency height, stable performance, high conformity, cost are low, therefore can be widely used in various the need with in the vibrative product of electromagnetism, as radiator, loudspeaker etc.
