Description

A kind of vibrating motor

Technical field

This utility model relates to mobile phone spare and accessory parts field, espespecially a kind of vibrating motor.

Background technology

Fast development along with electronic product, the especially mobile terminal device such as mobile phone, panel computer, these electronic equipments have use motor vibrations substantially, extensively using of touch screen increases with quick now, the purposes of small-size vibration motor also result in the concern of people, can feel during such as user's point touching screen button vibrating function and play game time can experience vibrating function really.And the structure of this multi-functional vibrating motor is different with existing vibrating motor from performance, it is desirable to its volume is little, is quick on the draw, vibration force is strong, the high-performance vibrating motor that the electric current that consumed is low.Because I am more and more thinner along with handset size, customer requirement motor space in mobile phone is more and more less, and after common motor is mounted on pcb board, the height of motor is plus the thickness of PCB, and integral thickness is bigger, it is difficult to meet the requirement of thin money mobile phone.

Utility model content

For solving the problems referred to above, this utility model provides a kind of vibrating motor.

nullFor achieving the above object，This utility model adopts the following technical scheme that and is: a kind of vibrating motor，Including balance weight、Motor body，Described balance weight is connected with motor body output shaft，Described motor body includes stator pack、Rotor set、End cap group，Stator pack includes shell、The permanent magnet of laminating outer casing inner wall and bearing，Permanent magnet upper end is located at by described bearing，Described permanent magnet is to have both ends open to have the cylinder of cavity，Described rotor set is located in cylinder cavity，Rotor set includes rotor、Commutator and rheostat，Described commutator is located at below rotor and coaxial rotating，Described rheostat surrounds commutator，End cap group includes end cap、The bearing with end cover being embedded in end cap、Brush forms，Described brush includes the first supporter、Elastic contact chip、Second supporter，First supporter and the second supporter are separately positioned on the both sides, center of bearing with end cover，Described rectification rotor is located at by the first supporter、Elastic contact chip、In the receiving space that second supporter encloses.

Preferably, described balance weight includes fan-shaped main body and the fixing seat being located in fan-shaped main body, and the center of circle radius of the upper surface inner arc of described fan-shaped main body is 2mm, and the center of circle radius of outer arc is 4mm, and inside and outside upper surface, fan-shaped arc spacing is 0.5mm.

Preferably, described shell is cuboid, and described shell and end cap junction are provided with opening, and described shell is connected by grab is fixing with end cap.

Preferably, described housing diameter is 6mm.

The beneficial effects of the utility model are: this utility model makes overall volume little by compact structure, and height only 3MM, this utility model makes vibration performance and startup time remain to meet the performance requirement of mobile phone by balance weight.
