Abstract

The invention provides a vibration assembly, a loudspeaker and electronic equipment. The vibration assembly comprises a dome, a vibrating diaphragm and a voice coil. The dome comprises a porous metal heat dissipation layer; a part of the vibrating diaphragm covers a part of the surface of the dome; the voice coil is connected with one surface of the dome back to the diaphragm. The vibration assembly and the loudspeaker are good in heat dissipation effect and can work normally for a long time, so that the acoustic performance of the loudspeaker and the electronic equipment is ensured, and the user experience is improved.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, in particular to a vibrating component, a loudspeaker and electronic equipment. Background technique [0002] Electronic devices such as phones, tablets, and smart speakers include speakers that give them the ability to play audio. The speaker includes a diaphragm and a voice coil, and the diaphragm is driven to vibrate to produce sound through the voice coil. However, the voice coil heats up during operation. If the heat is not dissipated in time, it will affect the normal operation of the voice coil and diaphragm. Contents of the invention [0003] The present disclosure provides an improved vibration assembly, speaker and electronic device. [0004] One aspect of the present disclosure provides a vibration assembly comprising: [0005] Dome, including porous metal heat dissipation layer; [0006] a diaphragm partially covering a portion of the surface of the dome; a...
