Novel regular quadrilateral voice coil

Technical Field

The utility model belongs to the technical field of loudspeakers, and particularly relates to a novel regular quadrilateral voice coil.

Background

In recent years, with the development of science and technology, especially the rapid progress of mobile communication technology, more and more mobile electronic devices are appearing in people's daily life, such as smart phones, tablet computers, notebook computers and multifunctional media players, which have become indispensable daily necessities. In these mobile electronic devices, the voice playing device is an indispensable component inside the mobile electronic devices, and the quality of the voice directly affects the user experience when the user uses the mobile electronic devices.

The voice coil is one of the important components of the horn, and is a key component for determining the service life of the horn. The working principle is as follows: when the alternating audio current passes through the voice coil, the voice coil generates alternating current which changes along with audio frequency, cuts magnetic lines of force to generate mechanical vibration, and drives the vibration basin to vibrate to make sound. The quality of the voice coil is related to the material, winding method and shape of the voice coil. The common voice coil framework materials comprise an aluminum sheet and a paper, and the electrical insulation property, high temperature resistance and other properties of the materials are mainly considered. The commonly used voice coil usually adopts a circular or oval aluminum sheet framework, the occupied space is relatively large, and the assembly of an ultra-thin notebook computer and the assembly of a micro electronic device are inconvenient.

The patent number is CN201520190594.7 discloses a voice coil loudspeaker voice coil and be equipped with speaker of this voice coil loudspeaker voice coil, relates to electroacoustic product technical field, forms by the voice coil line coiling, the cross section of voice coil line is the rectangle, four bights of rectangle voice coil line all are equipped with circular arc chamfer, the ratio of long limit size and minor face size of rectangle voice coil line is 1.05 ~ 3.15, just the extending direction on long limit of rectangle voice coil line with the direction of height of voice coil loudspeaker voice coil is unanimous.

The traditional voice coil is not strong enough in structural stability, and is easy to crack a framework, separate the framework from the voice coil and cause the problems of wire scattering and wire breaking of the voice coil; the structure of the voice coil affects the power of the loudspeaker, and the insufficient power causes the low experience feeling provided by the loudspeaker; the structure is not small and exquisite, and the subassembly is many, needs to accomplish fixed connection's problem with the help of the subassembly, and we propose a novel positive quadrilateral type voice coil loudspeaker voice coil for this reason.
