Abstract

The utility model discloses a voice coil which comprises a voice coil framework and a diaphragm arranged in an upper position and a lower position respectively. The voice coil framework and the diaphragm and are vertically connected. A flat voice coil wire based on winding wires on the inner layer and the outer layer of the voice coil framework is enwrapped on the voice coil framework. The voice coil has the advantages that the heat radiation area is greatly improved, and the good pointing performance can be simultaneously generated, so as to broaden the frequency response curve of the high frequency section of an althorn.

Description

A kind of voice coil loudspeaker voice coil

Technical field

The utility model relates to a kind of loudspeaker parts, particularly a kind of voice coil loudspeaker voice coil.

Background technology

In the prior art, the coiling of the speech coil framework of voice coil loudspeaker voice coil adopted carry out two-layer or multilayer winding outward, as shown in Figure 1 based on speech coil framework.

The utility model content

The purpose of this utility model is to disclose a kind of voice coil loudspeaker voice coil, and it is bad to overcome existing voice coil loudspeaker voice coil heat radiation, the problem that pointing capability is not good.

A kind of voice coil loudspeaker voice coil described in the utility model comprises connecting speech coil framework and the diaphragm that is provided with up and down, is wound with the lenticular wire voice coil loudspeaker voice coil wire rod based on the coiling of speech coil framework ectonexine on the speech coil framework.

Preferably, the voice coil loudspeaker voice coil wire rod passes through the outer field alternately winding of speech coil framework internal layer on speech coil framework.

Voice coil loudspeaker voice coil of the present utility model, area of dissipation improves greatly, can produce good pointing capability simultaneously, and then widen the frequency response curve of loudspeaker HFS.

Fig. 3 is a kind of voice coil loudspeaker voice coil overall structure of the utility model schematic diagram;

Fig. 4 is the winding schematic diagram of the utility model speech coil framework.

Mark the following drawings mark thereon in conjunction with the accompanying drawings:

1-lenticular wire voice coil loudspeaker voice coil wire rod, 2-speech coil framework, 3-diaphragm.

Embodiment

Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection range of the present utility model is not subjected to the restriction of embodiment.

Fig. 2 is the overall structure decomposing schematic representation of a kind of voice coil loudspeaker voice coil of the utility model, and Fig. 3 is a kind of voice coil loudspeaker voice coil overall structure of the utility model schematic diagram, and Fig. 4 is the winding schematic diagram of the utility model speech coil framework.

As Fig. 2-shown in Figure 4, a kind of voice coil loudspeaker voice coil of the utility model comprises speech coil framework 2 and the diaphragm 3 that connects setting up and down, be wound with lenticular wire voice coil loudspeaker voice coil wire rod 1 on the speech coil framework 2 based on the coiling of speech coil framework 2 ectonexines, particularly, lenticular wire voice coil loudspeaker voice coil wire rod 1 is by outer one decks of one deck (or multilayer) (or multilayer) in the speech coil framework 2 are replaced winding on speech coil framework 2.

Voice coil loudspeaker voice coil of the present utility model is mainly used in loudspeaker, bass horn or full range loudspeaker, can improve the useful life of loudspeaker and the power of loudspeaker, because voice coil loudspeaker voice coil of the present utility model has adopted the winding of inside and outside coiling, the area of dissipation of its coil is 2 times of common winding voice coil loudspeaker voice coil area of dissipation, and area of dissipation improves greatly.In addition, the lenticular wire voice coil loudspeaker voice coil can increase the effective length of coil in the magnetic gap greatly, thereby increases the BL value of loud speaker, the sensitivity that improves loud speaker.

Voice coil loudspeaker voice coil of the present utility model can be widened the frequency response curve of loudspeaker HFS, improves the pointing capability of loudspeaker greatly; Voice coil loudspeaker voice coil is the main source of loud speaker power, the acquisition of common voice coil loudspeaker voice coil power is by the outer coil effect, can't guarantee its stationarity, therefore its pointing capability is relatively poor, and the winding of inside and outside coiling can make voice coil loudspeaker voice coil act on acquisition power simultaneously by the ectonexine coil, knee-action is very steady, can produce good pointing capability, therefore can widen the frequency response curve of loudspeaker HFS.

More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.

Claims

1. a voice coil loudspeaker voice coil is characterized in that, comprises connecting speech coil framework and the diaphragm that is provided with up and down, is wound with the lenticular wire voice coil loudspeaker voice coil wire rod based on described speech coil framework ectonexine coiling on the described speech coil framework.

2. voice coil loudspeaker voice coil according to claim 1 is characterized in that, described voice coil loudspeaker voice coil wire rod passes through the outer field alternately winding of described speech coil framework internal layer on described speech coil framework.
