Horizontal linear vibration motor

Abstract

The present invention relates to a horizontal linear vibration motor, and more particularly, to a horizontal linear vibration motor in which a stopper rod comprising a non-magnetic body in the form ofa rectangular flat plate is formed, the stopper rod having, at both ends of a stopper rod main body, assembly groove parts having any one of a semicircular shape, an elliptical shape, and a polygonalshape; a yoke plate fixing groove part is formed by a guide form introduced from the central part of the stopper rod main body to the inner side, and a support sheet is formed by protruding to the outer side from the inner part of the guide form; the assembly groove parts are arranged at a specified interval towards the inner side. A projection for spring protection is formed to project upward, thereby preventing deformation of the spring due to impact of the weight portion, enabling the vibration motor to be driven horizontally, improving resonance noise of the camera, maximizing concentration of an intermediate electromagnetic field, and improving vibration response time.

Description

technical field [0001] The invention relates to a horizontal linear vibration motor, in particular to a horizontal linear vibration motor, which enables the vibration motor to be driven horizontally, thereby improving the resonance noise of the camera, maximizing the concentration of the intermediate electromagnetic field, thereby improving the vibration response time. Background technique [0002] Generally, with the recent rapid development of wireless communication technology, portable communication devices are gradually becoming smaller and lighter. With this trend of miniaturization and lighter weight, including devices mounted inside portable communication devices The components of mechanical devices, IC chips and circuits have become highly concentrated and highly functional, so in order to improve space utilization, it is necessary to improve the size and shape. [0003] Furthermore, a large amount of research has been carried out on a flat vibration motor that is in...

AI Technical Summary

Problems solved by technology

[0004] The initial model of the vibration motor installed in a portable communication device is a rotary vibration motor with a stator and a rotor as the basic structure. In this rotary vibration motor, the pole is fixed on the bracket of the stator so that the rotor is mounted on the pole. The upper part is supported to rotate to generate vibration. In order to increase the vibration force, the volume of the rotor is increased, or the number of revolutions is increased to improve the vibration force. However, due to structural problems, there are limitations in miniaturization and high vibration. There are great difficulties, and there is also a problem that it is difficult to ensure a life span beyond the specified time
