Abstract

The invention discloses a miniature vibration motor which comprises a stator, a rotor and a motor shell. The rotor comprises a coil winding, a rotor core, a commutator and a central shaft, one end of the central shaft is provided with an end cover, and the end cover covers one end of the motor shell; the stator sleeves the rotor and is used for generating a rotating magnetic field and providing the rotating magnetic field for the rotor; the rotor is used for rotating in a rotating magnetic field generated by the stator to generate load torque and transmitting the load torque to the standard vibrator and the exhaust vibrator through the central shaft; the standard vibrator is eccentrically sleeved on the central shaft; the exhaust vibrator sleeves one end, close to the standard vibrator, of the central shaft; an electrode contact connected with a coil winding in the motor is arranged at the bottom of the motor shell; the commutator is electrically connected with the coil winding; an electric brush is arranged on the end cover and is connected with external direct current through an electrode contact; and the commutator is used for converting the direct current accessed through the electric brush into the alternating current in the rotor winding, so that the direction of the load torque is not changed.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a miniature 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. Existing motors have a single function. In order to improve the performance o...
