Summary of the invention
For above defect, technical problem to be solved by this invention is to provide a kind of loud speaker, and this loud speaker ring and speech coil framework adhering state are good, and bonding difficulty is low, and leakage glue can not occur, and good product consistency, acoustical behavior is good.
For solving the problems of the technologies described above, the technical scheme of the present invention is:
A kind of Microspeaker, comprise shell, vibrational system and magnetic circuit system is contained in described shell, described vibrational system comprises voice coil loudspeaker voice coil, is bonded in the dust-proof cap above the ring of the skeleton periphery of described voice coil loudspeaker voice coil and skeleton, being arranged with retaining ring outside described skeleton, described retaining ring is arranged on the lower section of described skeleton with described ring phase bonding location.
Wherein, described magnetic circuit system comprises magnetic conductive part and the magnet being fixed on successively on described magnetic conductive part and washer.
Implementing mode as one, described magnetic conductive part is U iron, and the sidewall of described U iron is fixed on the inwall of described shell.
Implementing mode as another kind, described magnetic conductive part is T iron, and described washer is fixed on the inwall of described shell.
Wherein, the inwall of described shell is provided with the positioning boss of protrusion, and the upper surface of described U iron or described washer and the lower surface of described positioning boss fix.
After have employed technique scheme, the invention has the beneficial effects as follows:
Owing to the vibrational system of loud speaker of the present invention comprises voice coil loudspeaker voice coil, is bonded in the dust-proof cap above the ring of the skeleton periphery of described voice coil loudspeaker voice coil and skeleton, the periphery of skeleton is also arranged with retaining ring, and retaining ring is positioned at the lower section of the position that skeleton combines with ring.The bonding location of ring is served position-limiting action by retaining ring, it is possible to ensure the consistence of ring bonding location, and bonding difficulty is low, production efficiency height. Simultaneously the bonding glue of ring and skeleton is served the effect of barricade by retaining ring, effectively prevents leakage glue, glue distribute evenly, bonding stability is bigger, can not affect the acoustical behavior of loud speaker because glue distribution is uneven, and acoustical behavior improves.
Owing to the inwall of shell is provided with the positioning boss of protrusion, the upper surface of U iron or washer and the lower surface of positioning boss fix, positioning boss is serving positioning action, improve the contact area that simultaneously also add between magnetic circuit system and shell of the consistence of product, thus improve between magnetic circuit system and shell in conjunction with firmness, effectively reduce the risk that magnetic circuit system comes off from shell, it is to increase the reliability of product and work-ing life.
In sum, loud speaker of the present invention solves the technical problems such as the consistence that in prior art, loud speaker ring is bonding is poor, acoustical behavior difference, and speaker product consistence of the present invention is good, acoustical behavior height, production efficiency height, reliability height, it may also be useful to the life-span is long.
