Description

A kind of loud speaker

Technical field

The utility model relates to a kind of sonic vibration device, refers in particular to a kind of by utilizing electromagnetic force to produce the loud speaker of mechanical oscillation sounding.

Background technology

As everyone knows, loud speaker is commonly called as " loudspeaker ", and it is a kind of electro-acoustic element that converts electrical energy into acoustic energy.The kind of loud speaker is a lot, though their working method difference finally all is to promote ambient air by producing mechanical oscillation, makes air dielectric produce fluctuation, thereby realizes the conversion of " electricity-Li-sound ".Widely applying the loud speaker aspect high-fidelity music center now, all is dynamic speaker mostly; The manufacturing process steps of conventional loudspeakers comprises that adhesion T iron or U iron, adhesion basin frame and magnetic return, and upper terminal, puts and plays ripple, epenthesis circle, puts the outstanding limit of bulging paper supervisor; At first to required material preparation from top to bottom, be made by hand from the inside to surface; And in manufacturing process; each procedure and step all need to beat repeatedly bonding each parts of glue; the loud speaker that technological requirement is high; to the quality of glue and the very strictness of operation requirement of playing glue; glue is chemical standpoint with that; generally be with Fan Dewaerli or hydrogen bond combination, the combination of very rare chemical bond is so usually have then reliability problems.Time has been grown and has afterwards caused then not firm the generation to peel off phenomenon easily owing to the oxidation of glue.And entire product will pass through the multiple tracks bonding process, adopts artificial mode to carry out owing to glued joint, and therefore makes complicatedly, can't ensure loud speaker consistency and stability, also can't guarantee the quality of entire product, limited its scope of application.The tradition gluing is also very high to the dense thick requirement of glue, is that the too thick gluing machine of glue can't be played glue, transfers too rare overflow everywhere again, shines into bulging paper vibrating reed very high bad by the glue adhesion as with outstanding edge joint above the drum paper vibrating reed.What of the amount of glue all can directly have influence on product quality with uniformity or the like; And need to operate by production process and standard closely, each procedure need increase the tool of a lot of necessity, as the voice coil loudspeaker voice coil of adhering need advise tool location with sound, and putting into that magnetic returns need be fixing or the like with magnetic rule, and technological process is very loaded down with trivial details, consume a large amount of artificial, not so, a step is wrong, will influence the loud speaker effect or scraps, simultaneously because the material and a large amount of various glue that use, can't reclaim and cause unnecessary waste; And whole manufacture craft flow process very complicated, substantially by manual operation, production efficiency is low, and many batches of all variant, the shortcomings such as quality is unstable, product percent of pass is low of the product of producing.

The patent No. as the applicant's application is ZL200720108969.6, authorizing publication number is a kind of electromagnetic vibrator patent of CN201064771Y, though efficiently solve manufacture craft flow process very complicated, reduced artificial, improved production efficiency and product percent of pass; But the product of producing is primarily aimed at ultrathin dull and stereotyped vibrator, and shape is comparatively single, is difficult to change its outward appearance and shape according to concrete needs.
