Abstract
The present utility model discloses a large power voice coil which comprises a voice coil skeleton, a voice coil wire and an outer leading-out wire. The voice coil is characterized in that the voice coil skeleton is formed by winding a flexible printed board, the flexible printed board is composed of a substrate, an adhesive and a conducting layer, the flexible printed board is provided with two copper coil electrodes, and the two copper coil electrodes are respectively welded with the voice coil wire and the outer leading-out wire. The large power voice coil is simple in structure and is formed only by reeling the flexible printed board into a loop, and welding the voice coil wire and the outer leading-out wire on the copper foil electrodes of the flexible printed board, and as the direct welding is adopted, the process is simple and the solidity is good.
Description
Technical field
The utility model relates to a kind of voice coil loudspeaker voice coil, particularly high-power voice coil loudspeaker voice coil.
Background technology
Voice coil line on the existing voice coil loudspeaker voice coil has two kinds usually with the link method of outer lead-out wire, and a kind of is direct welding, is exactly voice coil line is directly welded with outer lead-out wire; Then that weld and skeleton is bonding, this method is easy to generate defective, and product is often in use shaken disconnected; Another kind method is when the voice coil loudspeaker voice coil coiling, on skeleton, puts a copper bar earlier, after voice coil loudspeaker voice coil winds; Utilize it that voice coil line and outer lead-out wire are welded together again; This method operation requires high, complex procedures, and cost is high.
Summary of the invention
The purpose of the utility model is that a kind of simple in structure, high-power voice coil loudspeaker voice coil that steadiness is high is provided for the deficiency that solves above-mentioned prior art.
To achieve these goals, the high-power voice coil loudspeaker voice coil that the utility model designed comprises speech coil framework, voice coil line, outer lead-out wire, it is characterized in that speech coil framework is formed by the flexible printed circuit coiling; Flexible printed circuit is provided with two copper foil electrodes; Two copper foil electrodes weld with voice coil line and outer lead-out wire respectively.
Said flexible printed circuit is made up of base material, adhesive and conductive layer, and adhesive is between base material and conductive layer.
Said copper foil electrode is arranged on the base material of flexible printed circuit, and copper foil electrode is located at outside the speech coil framework.
The high-power voice coil loudspeaker voice coil that the utility model obtains, simple in structure, only need welding voice coil line and outer lead-out wire on above that the copper foil electrode after the lopping of flexible printed circuit coiling, and direct the welding makes that operation is simple, fastness good.
