Horizontal vibrator

Abstract

The invention discloses a horizontal vibrator comprising a stator, a vibration unit, and a leaf spring unit, wherein the rotor comprises a support and a hollow coil, and the support and a housing are mounted together for limiting inner space, the coil being mounted on the support and being provided with a horizontal axis line. The vibration unit includes a magnet unit which penetrates the inner part of the coil and is provided with a magnet, the magnet being disposed on a side opposite to the magnet and being configured in a manner such that the magnetic poles of the magnet face each other; amagnetic yoke which surrounds the magnetic unit and the outer part of the coil and supports an end portion opposite to the magnetic unit; and a quality body which is disposed on the outer part of themagnetic yoke and is connected to the entire magnetic yoke so as to move along with the magnetic yoke. The leaf spring unit comprises a first leaf spring and a second leaf spring which is connected to the first leaf spring.

Description

[0001] Cross references to related applications [0002] This application claims the priority of the Korean patent application named “Horizontal Linear Vibrator” with the application number 10-2009-0094731 dated October 6, 2009, and the entire priority application is hereby incorporated by reference. In this application. Technical field [0003] The present invention relates to a horizontal linear vibrator. Background technique [0004] In order to avoid people from being disturbed by the noise of portable electronic devices (such as mobile phones, electronic game consoles or personal digital assistants), portable electronic devices have applied various types of vibration generators. Specifically, the vibration generator is installed in the mobile phone and serves as a silent call signal generator. In recent years, with the miniaturization and thinning of mobile phones, vibration generators installed in mobile phones also need to be miniaturized and have higher performance. [0005...

AI Technical Summary

Problems solved by technology

[0011] However, the problem with this conventional vertical linear vibrator 10 is that the amount of vibration is proportional to the product of the weight of the vibration unit 40 and its displacement, and thus, in order to obtain the desired amount of vibration, it is necessary to increase the weight or displacement of the vibration unit 40

This would undesirably increase the vertical thickness of the vertical linear vibrator 10

Moreover, it is difficult to miniaturize and thinn the mobile phone

[0012] In addition, a problem with the conventional vertical linear vibrator is that the vertical linear vibrator uses one leaf spring 50, so when the displacement of the vibrator 10 is large, stress concentration occurs on the bent portion of the leaf spring 50, possibly causing the Leaf spring 50 broken
