AI Technical Summary

Problems solved by technology

However, the aforementioned rotating motor is an existing DC brushed motor, so that the thickness of the vibration module cannot be further reduced
Furthermore, since the above-mentioned eccentric assembly is arranged outside the rotating motor and connected to the rotating shaft of the rotating motor, the length of the vibration module cannot be further reduced, so the vibration module cannot be further reduced in size.
In addition, the vibration module composed of a rotating motor and an eccentric component can only generate vibration in a single direction or a single plane

Abstract

This discloses the embodiment and provides a vibration device, contains a stator, an eccentric wheel and an electromagnetic drive assembly. This eccentric wheel is used for around a rotation axis rotatoryly for this stator. This electromagnetic drive assembly contains an at least magnetic component and an induction coil. An at least magnetic component sets up on this eccentric wheel. This induction coil corresponds magnetic component, and this induction coil sets up on this stator. Wherein, when an electric current offers this induction coil, produce this eccentric wheel of electromagnetic force drive around this rotation axis rotation with magnetic component to make this vibration device produce vibrations. Wherein, this rotation axis sets up on this stator.

Description

technical field [0001] The invention relates to a vibrating device, in particular to a vibrating device which utilizes an induction coil and a magnet to generate electromagnetic force to generate vibration. Background technique [0002] With the development of technology, many electronic devices (such as tablet computers or smart phones) now have a vibration reminder function. Through the vibration module set on the electronic device, when the electronic device performs a specific function, it can send out a vibration to remind the user. For example, when the electronic device receives a message or when the user presses the button of the electronic device, it can send out Vibration to remind the user. [0003] In the current vibration module, a rotating motor rotates an eccentric assembly to generate vibration. However, the aforementioned rotating motor is an existing DC brushed motor, so that the thickness of the vibrating module cannot be further reduced. Furthermore, s...
