Abstract
The utility model relates to a novel vibration magnetic circuit vibration speaker, which comprises a cap-shaped conducting magnet; the cap top of the magnet and a circular magnetic steel form a magnetic gap; a quality block is inlaid in the cap top and coaxially fixed with a spring plate by a rivet. The speaker has the functions of the prior vibrators and speakers, and overcomes three main defects of the prior art, i.e. poor vibration effect, small rated power and short service life.
Description
Technical field
The utility model belongs to other sound---pickoff group in International Patent Classification (IPC), i.e. H04R, the particularly vibrator used of mobile communication terminal, device, the parts of loud speaker unification.
Background technology
General vibrating speaker mainly contains magnet steel, clamping plate, magnetic cover composition magnetic circuit, and quality loop, latch plate and above-mentioned magnetic circuit are formed the vibration magnetic circuit, and protecgulum, voice coil loudspeaker voice coil, sound film, base, terminal block, bonnet and vibration magnetic circuit are formed vibrating speaker.Described vibration magnetic circuit is to be nested with quality loop and latch plate in magnetic cover outer rim and use adhesive, voice coil centered in the magnetic cover with magnet steel outside the centre.The vibrating speaker that this structure is formed can calling vibration, saves independent vibrator, has saved the space, has alleviated the difficulty of wires design, makes bass that improvement arranged because of quality loop again.But it has following three main disadvantages: one, because the quality loop present position has determined its geometry, make it can't obtain enough big quality and strengthen vibrating effect; Two, latch plate and magnetic circuit and quality loop anotherly directly were kept in motion in when work, and adhesive has had certain restriction useful life to product; Three, the little unfavorable heat radiation of voice coil diameter, voice coil line footpath can not overstriking, can certain limitation have been arranged to the rated power of product.
The utility model content
The purpose of this programme is to provide the novel vibrating magnetic circuit vibrating speaker of a kind of more strong vibration effect, long service life, bigger rated power.
It is as follows to disclose new technical scheme:
A kind of novel vibrating magnetic circuit vibrating speaker, coaxial protecgulum, sound film, voice coil loudspeaker voice coil, clamping plate, magnet steel, magnetic conduction iron, mass, latch plate, rivet, base and the terminal block of being equipped with also comprises bonnet.
Magnetic conduction iron is the cap shape, and shade is identical with the magnet steel diameter, and crown stretches in the magnet steel and constitutes magnetic gap with it.
With the co-axially fixed voice coil loudspeaker voice coil of sound film, pass that clamping plate are coaxial to be suspended among the above-mentioned magnetic gap.
With the suitable mass of magnetic conduction chapeau de fer top internal diameter, be entrenched in crown inside after, coaxial being attached on the latch plate, three's center by closing-up together.
By the sample of this scheme trial-production, because the replacing of magnet steel and mass position, the quality of mass has had significantly to be increased, thereby has obviously strengthened vibrating effect.Had rivet that the hollow magnetic conduction iron of T shape, mass, latch plate riveted are fixed together, riveted has fixedly replaced adhesive, has therefore prolonged useful life.Voice coil loudspeaker voice coil is displaced to mass, the hollow magnetic conduction iron of the T shape outside, voice coil diameter is enlarged, improved the radiating effect of voice coil loudspeaker voice coil, voice coil loudspeaker voice coil is under identical resistance value, because voice coil diameter strengthens back voice coil line footpath chap, the improvement of radiating effect and voice coil line footpath chap make product have bigger rated power, have solved three main disadvantages of general vibrating speaker.
