Voice coil and winding method thereof and loudspeaker with voice coil

Abstract

The invention provides a voice coil and a winding method thereof and a loudspeaker with the voice coil. A winding switching part is arranged between every two adjacent layers of coils, the two ends ofeach winding switching part are located at the top and the bottom of the voice coil respectively, one end of each winding switching part is connected with the wire outlet end of the inner side of thecorresponding two adjacent layers of coil structures, and the other end of each winding switching part is connected with the wire inlet end of the outer side of the corresponding two adjacent layersof coils; and the output end of the voice coil is obliquely pulled downwards from the top of the Nth layer of coil to the bottom of the (N-1)th layer of coil and is wound to the Nth layer along the bottom of the (N-1)th layer of coil, so that the output end of the voice coil and the input end of the voice coil are positioned on the same side of the voice coil. The wire outlet end of the Nth layerof coil of the voice coil is obliquely pulled to the bottom of the (N-1)th layer of coil and is wound to the Nth layer of coil along the bottom of the (N-1)th layer of coil, so that the voice coil ofwhich the voice coil output end and the voice coil input end are positioned on the same side of the voice coil, the voice coil winding method and the loudspeaker comprising the voice coil are formed.

Description

【Technical field】 [0001] The invention relates to the technical field of acoustic design, in particular to a voice coil and its winding method, and a loudspeaker with the voice coil. 【Background technique】 [0002] In the related art, the loudspeaker includes a pot frame and a vibration system and a magnetic circuit system accommodated in the pot frame. The vibration system includes a voice coil, and the voice coil includes a voice coil input end, a voice coil output end, and a voice coil winding wire. The winding wire is wound from the inner side of the voice coil to the outer side to form a multi-layer structure. [0003] In the loudspeaker with a magnetic circuit in the direction of the long axis and no magnetic circuit in the direction of the short axis, the voice coils are arranged in an odd number of layers, the incoming and outgoing lines are distributed on the upper and lower end faces of the voice coil, and the outgoing lines on the upper end face are bent downward....

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a voice coil, a voice coil winding method and a speaker with the voice coil, so as to solve the problem that the curved wire on the upper end surface of the voice coil collides with the voice coil during the vibration process of the voice coil
