Problems solved by technology

[0003] In the case of long-term high-intensity work, the high heat generated by the voice coil is easy to accumulate in the small space in the magnetic gap and cannot be dissipated quickly. The acoustic performance of the speaker deteriorates, and the glue between the voice coil wires in the voice coil is easy to melt at high temperature, resulting in a decrease in adhesion, and the voice coil is prone to the risk of loose wires. Once the voice coil is loose, the speaker system will not work properly

Abstract

The invention discloses a loudspeaker. The loudspeaker comprises a shell body, a magnetic circuit system and a vibration system, wherein a magnetic gap is formed in the magnetic circuit system, the vibration system comprises a vibrating diaphragm and a voice coil, the vibrating diaphragm is fixed on the shell body, one end of the voice coil is connected onto the vibrating diaphragm, the voice coil extends into the magnetic gap, and a first heat conducting layer is arranged on the internal surface of the magnetic gap. According to the loudspeaker disclosed by the invention, heat generated by the voice coil can be transferred rapidly, and wire loosening of the voice coil and heated deformation of the vibrating diaphragm caused by accumulation of the heat generated by the voice coil in a magnetic gap space are avoided.

Description

technical field [0001] The present invention relates to the field of electroacoustics, and more specifically, to a loudspeaker. Background technique [0002] With the rapid development of portable electronic devices, the appearance of micro-speakers is becoming thinner and thinner, the miniaturization trend is obvious, the magnetic gap space is getting smaller and smaller, and the power is getting higher and higher. Generally, the loudspeaker includes a casing, a magnetic circuit system and a vibration system. The vibration system includes a diaphragm and a voice coil connected together, and a magnetic gap is provided in the magnetic circuit system. As the power of the speaker increases, the voice coil also generates a lot of heat, which puts forward stricter requirements on the heat dissipation performance of the speaker. The heat dissipation performance of the speaker system directly determines the reliability of the speaker. [0003] In the case of long-term high-intensi...
