Abstract

Provided is a vibration and vocalization device, comprising a housing, and a vocalization system and vibration system which are accommodated in the housing, and an elastic support member used for suspending the vibration system in the housing, wherein the vocalization system comprises a vibrating diaphragm and at least one coil which is vertically fixed on one side, facing the vibration system, of the vibrating diaphragm; a central axis of the coil is parallel to a plane where the vibrating diaphragm is located, and is vertical to a vibration direction of the vibration system; the vibration system comprises a mass block and at least one permanent magnet provided on the mass block; the mass block is provided thereon with a through hole adapted to the coil; the coil yields in the through hole; and the coil and the permanent magnet form a sandwich structure. The vibration and vocalization device can improve the space utilization rate of a product and the performance of a product.

Description

technical field [0001] The present invention relates to the technical field of consumer electronic products, and more specifically, relates to a vibration and sound generation device with vibration and sound generation functions. Background technique [0002] With the development of portable terminal consumer electronics products, people have increasingly strong requirements for the functions of such products. In terms of functions such as mobile phone music, in order to make the entertainment effect stronger and the user experience better, there have been playing music The mode that can vibrate at the same time, the performance requirements for the sound generating device with vibration function are gradually increasing. [0003] At present, the vibration and sound generating device is mainly by setting elastic supports on the fixed magnetic system in the transmission speaker products, suspending the magnetic circuit system through the elastic supports, and increasing the v...
