Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] In order to solve the technical problem, the present invention provides a voice coil on the one hand. figure 1 It is a schematic diagram of an embodiment of the voice coil structure of the present invention, refer to figure 1 The voice coil 100 has a cubic structure as a whole. The voice coil 100 includes a voice coil input terminal 110, a voice coil output terminal 120, and a voice coil winding 130. The voice coil 100 is sequentially wound from the inside to the outside to form a three-layer coil structure 140. These are the first layer coil 141 , the second layer coil 142 , and the third layer coil 143 , and each layer of coil structure 140 is wound to form a multi-turn structure. A winding switching portion 150 is provided between two adjacent layers of coil structures. The winding switching portion 150 is a concave structure, and the winding...

Abstract

The invention provides a voice coil and its winding method and a loudspeaker with the voice coil. A winding switching part is arranged between two adjacent layers of coils, and the two ends of the winding switching part are located at the top and bottom of the voice coil respectively. , one end of the winding switching part is connected to the inner outlet end of the adjacent two-layer coil structure, and the other end is connected to the outer inlet end of the adjacent two-layer coil; the output end of the voice coil is from the top of the Nth layer coil Pull down to the bottom of the N-1th layer coil and wind along the N-1th layer coil bottom to the Nth layer, so that the voice coil output end and the voice coil input end are located on the same side of the voice coil. By pulling the outlet end of the Nth-layer coil of the voice coil to the bottom of the N-1-th layer coil and winding it to the N-th layer coil along the bottom of the N-1-th layer coil, a voice coil output terminal and a voice coil are formed. A voice coil with an input on the same side as the voice coil, a method of winding the voice coil, and a loudspeaker incorporating the voice coil.

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....
