Abstract

The invention discloses a manufacturing method of a voice coil assembly and a loudspeaker, the loudspeaker comprises a vibration system, the vibration system comprises a vibrating diaphragm and a voice coil assembly, the voice coil assembly comprises a first voice coil and a second voice coil, the first voice coil comprises a first body formed by winding enameled wires in multiple layers, and a first lead connected with the first body. The second voice coil comprises a second body formed by winding multiple layers of varnished wires, and a second lead connected with the second body; wherein the first body is provided with a first inclined plane facing the second body, the second body is provided with a second inclined plane corresponding to the first inclined plane, and the first inclinedplane and the second inclined plane abut against each other, so that the first voice coil and the second voice coil are stacked up and down. According to the technical scheme, the structural reliability of the voice coil assembly can be improved.

Description

technical field [0001] The invention relates to the technical field of loudspeaker products, in particular to a manufacturing method of a voice coil assembly and a loudspeaker. Background technique [0002] Miniature electroacoustic devices are widely used in portable electronic devices such as mobile phones, notebook computers, and hearing aids. With the rapid development of these portable electronic devices, people have higher and higher requirements for the miniature electroacoustic devices used in them. The voice coil is the moving part of the miniature sound-generating device. When the alternating audio current passes through the voice coil, the voice coil generates a magnetic field that changes with the audio current, and the changing magnetic field attracts or The repulsive effect causes the voice coil to generate mechanical vibration, which drives the vibration of the diaphragm of the micro-electro-acoustic device. The vibration of the diaphragm repeatedly pushes th...
