A horizontal vibrating linear motor

Abstract

The invention provides a horizontal vibration linear motor which comprises a motor shell, a cover plate and a vibration assembly. The cover plate is installed on the motor shell in a covering mode, an installation space is formed by the cover plate and the motor shell, the vibration assembly is hung in the installation space through location of elastic supporting pieces located on the two opposite lateral walls of the motor shell respectively and comprises a vibration block and a permanent magnet installed on the vibration block, the permanent magnet can drive the vibration assembly to perform reciprocated vibration in the direction basically parallel to the bottom face of the motor shell under the effect of the magnetic field force and enables the two elastic supporting pieces located on the opposite lateral walls to be correspondingly stretched and retracted in the vibration process, and a limiting device for limiting the reciprocated vibration amplitude of the vibration block is further installed in the installation space. According to the horizontal vibration linear motor, the capacity for overcoming faults such as short circuits can be improved, and the whole quality level of machines with the motor is easily improved.

Description

technical field [0001] The invention relates to a horizontal vibration linear motor, which belongs to the technical field of linear vibration motors. Background technique [0002] At present, mobile consumer electronics products on the market generally use vibration motors as system feedback components, such as mobile phone call notifications, game console vibration feedback, and so on. Existing vibration motors on the market mainly include cylindrical iron core motors, coreless motors and linear motors. Cylindrical iron core motors and coreless motors not only have complex structures, large thickness, and many manufacturing processes, but also have high motor noise and poor control accuracy. Nowadays, in order to meet the design requirements of thin, light and portable electronic consumer products, vibration motors are gradually developing in the direction of flat, light and thin. A linear vibration motor refers to a motor in which the vibration direction of the vibrator ...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the purpose of the present invention is to overcome the defect that when the current in the coil of the linear vibration motor in the prior art suddenly increases, it is easy to cause damage to the entire motor, which is not conducive to improving the overall quality level of the linear vibration motor machine, thereby providing a Strong adaptability, even if the current in the coil suddenly increases, it will not damage the elastic support and then damage the horizontal vibration linear motor of the entire linear vibration motor
