Description

Combined voice coil

Technical Field

The utility model relates to a speaker technical field especially relates to a voice coil loudspeaker voice coil that speaker was used.

Background

The loudspeaker generally comprises a voice coil, a vibrating diaphragm, a magnetic circuit, a shell and the like, wherein the voice coil is electrified to drive the vibrating diaphragm to vibrate so as to push air to vibrate and generate sound waves. The voice coil is an important component of the speaker and provides power to the speaker.

With the development of mobile phone technology, mobile phone stereo sound becomes a new development trend, in order to meet the Smart PA debugging requirement, under the limited input power, more excellent performance is obtained, and the requirements on the height, the resistance and the weight of a voice coil are higher. At present, most of voice coils are wound by enameled wires with single diameters, the height, resistance and weight of the voice coils are greatly limited, and the performance cannot be further improved. In order to improve this deficiency, it is necessary to improve the voice coil system by combining the voice coils to improve the performance of the speaker.

Fig. 5 is a schematic diagram of a conventional voice coil, using a full layer design. This type of structure adopts the enameled wire coiling of single kind diameter usually, receives very big restriction in balanced voice coil loudspeaker voice coil height, resistance and weight aspect, can't further promote the performance.

As shown in fig. 6, 7 and 8, a conventional voice coil combination method is adopted, and two kinds of enamelled wires with different wire diameters are wound to form a combined voice coil. The inner main voice coil is wound by adopting a varnished wire with a larger wire diameter to play a skeleton role. And the external small voice coil is wound by adopting a relatively thin wire diameter enameled wire. Because the large voice coil on the inner side is at least two full layers, otherwise, the voice coil cannot be wound successfully normally, and the wires are easy to be scattered. If the inboard big voice coil loudspeaker voice coil of this scheme adopts two-layer coiling, there is the high too high problem of leading to the vibration space not enough of speaker voice coil loudspeaker voice coil. If the inner large voice coil is wound by three layers, the start and end lines of the voice coil are arranged at the upper side and the lower side, so that the vibration system is easy to be unstable, and polarization is caused. If the large voice coil on the inner side is wound by four layers, the height of the voice coil is usually too low, the insertion magnetic gap of the voice coil is too small, and the harmonic distortion is too large. In order to solve the problem, the scheme of the special-shaped voice coil and the auxiliary small voice coil is adopted for optimization.
