Abstract
The utility model provides an electric loudspeaker, comprising a diaphragm, a voice coil, a magnetic circuit, a support and two kinds of movable suspension parts, wherein one kind is a folding ring encircling the diaphragm, and the other kind is a group of spring waves perpendicular to the diaphragm, the upper ends of the spring waves are bonded on the bottom surface of the diaphragm, the lower ends are bonded on the support, and the bonding points are outside the voice coil and outside the external diameter of the magnetic circuit. The electric loudspeaker having the structure becomes thinner, and no additional connector or magnetic circuit part with complicated shape is used.
Description
Technical field
The utility model relates to a kind of dynamic speaker.
Background technology
The dynamic speaker of general structure is seen Fig. 1, usually by vibrating diaphragm 1, voice coil loudspeaker voice coil, magnetic circuit, support 5 and two movably suspension hardware form, this suspension hardware is a ring 6 and a bullet ripple 7 that is parallel to vibrating diaphragm.Voice coil loudspeaker voice coil by outside voice coil loudspeaker voice coil pipe 3 and voice coil loudspeaker voice coil pipe 3 bottoms around voice coil loudspeaker voice coil coil 4 form, magnetic circuit is formed by washer 8, magnet 9, pad 10 and around the U sections 11 of above-mentioned three parts, copper cap 12 is enclosed within the outside of washer 8 and magnet 9.Ring 6 is suspended on the support 5 vibrating diaphragm 1, and voice coil loudspeaker voice coil pipe 3 upper ends and vibrating diaphragm 1 are bonding, plays ripple 7 voice coil loudspeaker voice coil pipe 3 appropriately also is suspended in the magnetic circuit with one heart.Ring 6 and play the hardness balance of ripple 7 suppresses the mobile amplitude of voice coil loudspeaker voice coil pipe 3 under the high-frequency resonance mode, prevents that therefore voice coil loudspeaker voice coil pipe 3 from running into the part of magnetic circuit.Dust cap 13 is fixed on the top of voice coil loudspeaker voice coil pipe 3.
Along with audio amplifier is more and more thinner, loud speaker also will design thinlyyer inevitably, or shorter.Conventional loud speaker is to be bonded on the voice coil loudspeaker voice coil with playing ripple, gapped requirement between voice coil loudspeaker voice coil, bullet ripple and magnetic circuit, and this has increased the height of loud speaker.Gap between vibrating membrane and the bullet ripple requires also to have increased the height of loud speaker.These gaps require to have restricted the attenuation of conventional loud speaker.
At above-mentioned restriction, exist two kinds of solutions.In first kind of solution, see Fig. 2, a bullet ripple connector 2 is introduced in the speaker design, and this plays the outside that ripple connector 2 is bonded in vibrating diaphragm 1 bottom and voice coil loudspeaker voice coil pipe 3, plays ripple 7 and is bonded on support 5 and the bullet ripple connector 2.In second workaround, see Fig. 3, changed the magnetic circuit of loudspeaker design, introduce an open magnetic circuit, the perforate that bullet ripple 7 passes magnetic circuit is bonded on the voice coil loudspeaker voice coil pipe 3 again.
More than two kinds of solutions can make play corrugated and magnetic circuit end face very near or clear-cut coplane, and make this loud speaker extremely thin.Though this loud speaker is very thin, adopt the stroke of the loud speaker of this method also can be similar with the stroke of general loud speaker, the extra part or the part of redesign have increased the complexity and the product cost of production technology.
Summary of the invention
Utility model purpose of the present utility model is to provide a kind of dynamic speaker, and the dynamic speaker of this structure can reduce the thickness of loud speaker, and does not use extra bullet ripple connector and complicated magnetic circuit component.
The utility model purpose can realize by following technical solution: a kind of dynamic speaker, comprise movably suspension hardware of a vibrating diaphragm, voice coil loudspeaker voice coil, magnetic circuit, support and two classes, described two classes are suspension hardware movably, one class is a ring around described vibrating diaphragm, it is characterized in that, the another kind of bullet ripple that is a group perpendicular to described vibrating diaphragm, the upper end of described bullet ripple is bonded in the bottom surface of described vibrating diaphragm, the lower end is bonded on the support, and adhesive spots is positioned at the outside of voice coil loudspeaker voice coil and the outside of magnetic circuit external diameter.
Preferably, the bullet ripple of described vertical direction, the adhesive spots of its lower end is parallel with the upper surface of described magnetic circuit or under it.
As can be seen, the bullet ripple of described vertical direction, the adhesive spots of its lower end can also be bonded in describedly on described magnetic circuit, and its adhesive spots can be in the outside of described voice coil loudspeaker voice coil cylinder, also can reach the same technique effect at the inner face of described voice coil loudspeaker voice coil cylinder.
Preferably, the bullet ripple of described vertical direction adopts the cloth of handling to knit material.
Preferably, the bullet ripple of described vertical direction adopts pliable and tough elastomeric material.
Preferably, the bullet ripple of described vertical direction adopts pliable and tough elastic fiber material.
Preferably, the bullet ripple of described vertical direction adopts the metal spring material of coiling.
Preferably, the bullet ripple of described vertical direction adopts the bending metals material.
Preferably, the bullet ripple of described vertical direction adopts the cloth of any processing to knit material material, pliable and tough elastomeric material, pliable and tough elastic fiber material, metal spring material, bending metals material and other any resilient suspension material of coiling.
In this utility model, the bullet wave structure that typically is parallel to vibrating diaphragm is replaced by one group of bullet ripple perpendicular to vibrating diaphragm.
Adopt the dynamic speaker of this structure, can use a thinner loud speaker, and do not use the magnetic circuit component of extra connector and complicated shape.

Embodiment
Embodiment: referring to Fig. 4 and Fig. 5, the dynamic speaker of the utility model embodiment, a vibrating diaphragm 1 is bonded on the ring 6, this ring 6 is bonded on the support 5 again, a voice coil loudspeaker voice coil pipe 3 is bonded in the bottom surface of above-mentioned vibrating diaphragm 1 by hookup 2, voice coil loudspeaker voice coil pipe 3 and its underpart around voice coil loudspeaker voice coil coil 4 be suspended among the magnetic circuit, this magnetic circuit is formed with the washers 8, magnet 9, pad 10 in footpath and round above-mentioned three U sections 11 with the footpath parts by three, bullet ripple 14 perpendicular to vibrating diaphragm 1, the one end is bonded in the bottom surface of vibrating diaphragm 1, and the other end is bonded on the support 5.
The function of this dynamic speaker is the same with traditional electrical dynamic formula loud speaker, voice coil loudspeaker voice coil pipe 3 and magnetic circuit convert electrical input signal to mechanical energy, this mechanical energy drives vibrating diaphragm 1 and produces an air pressure wave, ring 6 plays the effect of hanging vibrating diaphragm 1 with vertical bullet ripple 14, and voice coil loudspeaker voice coil pipe 3 is suspended in the magnetic gap.
