Abstract

The utility model discloses an improved trumpet structure which arranges a damper in the voice coil to reduce the volume (width) of the whole trumpet to enlarge the magnet, fix the voice coil, increase the power, reduce the amplitude of vibration and further reduce the poor part rate of the product. The traditional trumpet arranges the damper in the outside of the voice coil.

Description

Improved horn structure

Technical field

The utility model relates to a kind of improved horn structure, refers to especially a kind of damper is arranged on the loudspeaker of voice coil loudspeaker voice coil inside, can dwindle the volume of horn integral, increases magnet, increases power, and can reduce the fraction defective of product.

Background technology

The loudspeaker of general traditional type, as shown in Figure 1, in horn bulb 100 devices one magnet 200, magnet 200 tops are nested with a voice coil loudspeaker voice coil 300, the damper 400 that the installing one of voice coil loudspeaker voice coil 300 outer rims is made by cloth matter, voice coil loudspeaker voice coil 300 tops are installed a vibrating membrane 500 again; These loudspeaker of commonly using are because the damper 400 of transverse vibration is installed in voice coil loudspeaker voice coil 300 outsides, so the volume (width) of horn integral can't dwindle, and expend unnecessary space, loudspeaker under equal volume, this magnet 200 can't strengthen because of the outer damper of opening 400, loudspeaker magnetic relatively a little less than, so power output relatively a little less than.

In addition, existing loudspeaker are in order to possess stronger magnetic of loudspeaker and power output, under the situation that magnet 200 volumes equate, damper is not set, but the loudspeaker voice coil loudspeaker voice coil of this machine more built on the sand, power also can't increase and amplitude strengthens, thereby increases the fraction defective of product.

Summary of the invention

In view of this utility model designer accumulates and is engaged in this journey experience for many years, studies intensively and test improvement repeatedly, nowadays creates a kind of novel horn structure finally, and the habitual product shortcoming of can forgoing is to promote effect.

Main purpose of the present utility model is to provide a kind of improved horn structure, mainly damper is arranged on voice coil loudspeaker voice coil inside, with the volume (width) that dwindles horn integral, loudspeaker under the equal volume, magnet of the present utility model can strengthen, and with enhancing magnetic force, and then improves output power of speaker; Moreover damper is established in voice coil loudspeaker voice coil inside, and can surely die voice coil loudspeaker voice coil, increase power, minimizing amplitude are to reduce the fraction defective of product.Its concrete structure comprises horn bulb, magnet, voice coil loudspeaker voice coil, damper, vibrating membrane and dust cap, wherein the horn bulb bottom can be inserted for magnet, the magnet outer rim is nested with a voice coil loudspeaker voice coil, one vibrating membrane is nested with on voice coil loudspeaker voice coil with the center nose end, voice coil loudspeaker voice coil top and cover are put a dust cap, and it is characterized in that: damper is installed in voice coil loudspeaker voice coil inside, to dwindle the volume of horn integral, also can increase magnet, firm voice coil loudspeaker voice coil, increase power, reduce amplitude, to reduce the fraction defective of loudspeaker.

Understand for the utility model being had further, Zi Zuo is as follows with graphic detailed description the utility model:

Embodiment

See also Fig. 2～shown in Figure 3, the utility model by horn bulb 1, magnet 2, voice coil loudspeaker voice coil 3, play component compositions such as ripple 4, vibrating membrane 5 and dust cap 6 and form; The magnet groove of horn bulb 1 bottom can be inserted for magnet 2, magnet 2 outer rims also are nested with a voice coil loudspeaker voice coil 3, one vibrating membrane 5 is nested with on voice coil loudspeaker voice coil 3 with centre bore 51 ends, voice coil loudspeaker voice coil 3 open top end and cover cap one dust cap 6, the sound that vibrating membrane 5 resonance are sent then can be sent by the bellmouth orifice of horn bulb 1, and principal character of the present utility model is:

Damper 4 is arranged on voice coil loudspeaker voice coil 3 inside (as Fig. 3), owing to damper is installed in the interior mode that contracts but not open outward, so can dwindle the volume (width) of horn integral; If the utility model with commonly use loudspeaker and under equal volume (width), compare, magnet 2 of the present utility model can increase, thereby can increase magnetic force, and then improves output power of speaker.

If the magnet that the utility model and existing habitual loudspeaker have equal volume simultaneously, habitual loudspeaker do not add damper, and the utility model can add damper 43 li of voice coil loudspeaker voice coils, thus firmly voice coil loudspeaker voice coil, increase power, reduce amplitude, and can reduce the fraction defective of product.Moreover the utility model also can set up heat-barrier material 7 (as Fig. 3) in damper 4 bottoms, and this heat-barrier material 7 can reduce damper 4 and send overheated heat.

In sum, the structural improvement of the utility model loudspeaker, be to improve the structure that the traditional type loudspeaker are arranged on damper the voice coil loudspeaker voice coil outside, and damper is arranged on voice coil loudspeaker voice coil inside, except the volume (width) that can dwindle horn integral, also can increase magnet, firm voice coil loudspeaker voice coil, increase power and can reduce amplitude, and then reduce the fraction defective of loudspeaker; Its practical effect is when unquestionable.

Claims

1, a kind of improved horn structure, comprise horn bulb, magnet, voice coil loudspeaker voice coil, damper, vibrating membrane and dust cap, wherein the horn bulb bottom can be inserted for magnet, the magnet outer rim is nested with a voice coil loudspeaker voice coil, one vibrating membrane is nested with on voice coil loudspeaker voice coil with the center nose end, voice coil loudspeaker voice coil top and cover are put a dust cap, and it is characterized in that: damper is installed in voice coil loudspeaker voice coil inside.

2, improved according to claim 1 horn structure is characterized in that: the bottom of damper is set up to reduce the heat-barrier material of damper superheat.
