Horizontal linear vibration motor

Abstract

The invention discloses a horizontal linear vibration motor, which comprises a stator assembly, a vibration assembly and a housing provided with an accommodation space, wherein the housing comprises an upper housing and a lower bracket, and the stator assembly and the vibration assembly face each other and are arranged in the accommodation space of the housing; The stator assembly comprises an upper shell, a lower bracket and a magnet steel assembly, wherein the magnet steel assembly is fixedly connected with the upper inner shell surface of the upper shell; The vibration assembly includes a mass, elastic support, a coil and a flexible circuit board, the flexible circuit board has a U-shaped structure, The upper end face of the upper part of the U-shaped structure is connected with the lower end face of the mass block, the lower end face of the upper part of the U-shaped structure is electrically connected with the coil, the lower end face of the lower part of the U-shaped structure isfixedly connected with the lower bracket, and the two elastic supports are respectively arranged at the two ends of the mass block and fixedly connected with the mass block and the side wall of the upper shell. The invention has the advantages of low magnetic flux leakage of the motor, quick response of the motor and good vibration effect, and has good market application prospect.

Description

technical field [0001] The invention belongs to the field of miniature vibration motors, in particular to a horizontal linear vibration motor. Background technique [0002] Miniature vibration motors are indispensable components of electronic products such as mobile phones, tablet computers, and handheld game consoles, which provide users with tactile feedback. [0003] As the competition in the smartphone market intensifies, mobile phone manufacturers pay more and more attention to the user's tactile experience, and the vibration feedback effect of customers on the motor is also getting higher and higher. As a result, linear vibration motors that are different from traditional rotor motors have appeared on the market. Compared with traditional rotor motors, linear motors have great advantages in vibration characteristics, response time, service life, noise, etc., and they can provide a variety of vibration modes, providing users with rich and varied and delicate and realist...
