Problems solved by technology

However, the root of the incoming wire in the related art is on the inner side of the voice coil body, and the incoming wire needs to span the entire wall thickness of the voice coil body and extend to the outside of the voice coil body. A part will protrude from the side wall of the voice coil body, which will cause problems such as the incoming wire of the voice coil is higher than the surface of the voice coil body, the root of the AMS reliability incoming wire is broken, and the vibration is high.

Abstract

The invention provides a voice coil winding method, which is characterized in that an enameled wire is wound into a voice coil through a winding tool, and an inlet wire and an outlet wire of the wound voice coil are flush with the surface of a voice coil body. Compared with the prior art, the voice coil wound by the voice coil winding method provided by the invention can effectively reduce the risks of wire breakage and high-order vibration of the root part of the AMS reliable inlet wire and the overall height of the voice coil.

Description

【Technical field】 [0001] The invention relates to the field of wire winding, in particular to a voice coil winding method. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. Electroacoustic transducers used for sound-to-electric conversion are widely used in smart mobile devices such as mobile phones. [0003] The electroacoustic transducer includes a voice coil wound by a single enameled wire, and the voice coil includes a voice coil body and incoming and outgoing wires extending from the voice coil body. However, the root of the incoming wire in the related art is on the inner side of the voice coil body, and the incoming wire needs to span the entire wall thickness of the voice coil body and extend to the outside of the voice coil body, which will inevitably cause the incoming w...
