Abstract

The invention discloses a vibrating motor. The vibrating motor comprises a stator set, a circular rotor set and an end cover set, wherein the rotor set comprises a slotless cylindrical supporting portion, a commutator, a coil and a center shaft, the end cover set is arranged at the end of the center shaft and the end of a stator shell, the center shaft extends out of the stator shell and extends into a vibrator, the center shaft is sleeved with the vibrator, the coil is attached to the outer side of the supporting portion, the supporting portion is made of magnetism conduction materials or non-magnetism-conduction materials, and the circular commutator is arranged on the outer side of the center shaft in a cooperative mode, and is connected with the coil. According to the vibrating motor, the coil can be conveniently installed, the structure is simple, the size is micro, the vibrating motor is suitable for being attached to a PCB, and can be applied to the prompt function or the effective reminding function of communication terminal products such as a mobile phone and a tablet personal computer, it is ensured that the size of the vibrating motor is micro, a magnetic field air gap of the vibrating motor is ensured, the flux leakage phenomenon is avoided, and the vibration quantity of the vibrating motor is increased.

Description

technical field [0001] The invention relates to the field of small motors, in particular to a patch type vibration motor. Background technique [0002] With the rapid development of electronic products, especially mobile terminal devices such as mobile phones and tablet computers, these electronic devices basically use motor vibration. Today, the wide use and rapid growth of touch screens have also attracted people's attention to the use of small vibration motors, such as When the user clicks on the touch screen, he can feel the vibration function of the button and can truly feel the vibration function when playing games. And the structure and performance of this multifunctional vibrating motor are different from existing vibrating motors, requiring its volume to be small, responsive, vibrating force is strong, the high-performance vibrating motor that the electric current that consumes is low. The air gap of the existing small hollow cup motor is too large, the vibration e...
