Abstract

The present invention relates to a loudspeaker, which includes a housing and a vibration system located in the housing. The vibration system includes a diaphragm assembly and a voice coil. The voice coil is formed by coiling an enameled wire. Axis, the voice coil is divided into the upper part of the voice coil and the lower part of the voice coil, the upper part of the voice coil is connected with the diaphragm assembly, in the radial direction of the voice coil, the upper part of the voice coil is a single-layer enameled wire, the voice coil The lower part is at least two layers of enameled wire, and the upper part of the voice coil is bonded with reinforcing paper on the side thinner than the lower part of the voice coil in the radial direction, and the reinforcing paper connects the two ends of the upper part of the voice coil and the two ends enameled wire. A technical effect of the present invention is that the present invention can improve the reliability of the single-layer enameled wire structure on the voice coil.

Description

technical field [0001] The invention belongs to the technical field of acoustic-electric transduction, and more specifically, the invention relates to a loudspeaker. Background technique [0002] The loudspeaker is a transducing device that converts electrical signals into acoustic signals. Audio electric energy causes the vertebral basin or diaphragm to vibrate and resonate with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. In the prior art, the voice coil of some speakers will adopt a 1.5-layer voice coil structure, one part is one layer of enameled wire, and the other part is two layers of enameled wire, but during the working process of the speaker, with the vibration of the voice coil, the single layer of enameled wire It is easy to loose wires, which reduces the reliability of the product.
