Abstract

The present invention discloses a linear vibration motor and electronic equipment. The vibration motor comprises a housing, a coil, a vibrator and an elastic element. The housing has a cavity, the coil and the elastic element are arranged in the cavity, the vibrator comprises a permanent magnet, the vibrator is suspended in the cavity through the elastic element, and the coil is matched with the vibrator; the permanent magnet is arranged relative to the inner wall of the housing along the direction of vibration, and magnetic fluid is provided between the permanent magnet and the inner wall, or the permanent magnet is arranged opposed to the elastic element along the direction of vibration, and magnetic fluid is provided between the permanent magnet and the elastic element; and the magnetic fluid is adsorbed on the permanent magnet. The linear vibration motor disclosed by the present invention has a good damping effect.

Description

technical field [0001] The present invention relates to the technical field of vibration devices, and more specifically, to a damped linear vibration motor and electronic equipment. Background technique [0002] Miniature linear vibration motors generally include a vibration assembly and a stator assembly. The vibrating assembly consists of a mass block, a permanent magnet, and shrapnel or springs. The stator assembly is composed of FPCB, coil, limit block and buffer pad. [0003] Micro linear motors usually achieve reciprocating regular vibration through vibration components. The vibration experience is not only reflected in the magnitude of the natural frequency and vibration acceleration, but also in its response speed (that is, the time when the vibration frequency of the product rises and falls). The performance parameter of the response speed of the linear vibration motor (also known as the start-up braking time), the start-up braking time is affected by the damping ...
