Abstract

The invention discloses a flat vibration motor. The flat vibration motor comprises a shell assembly, a rotor assembly and a lower bracket assembly, wherein magnetic steel is arranged in the shell assembly; a rotary shaft, a coil, a heavy hammer and a commutator segment are arranged in the rotor assembly; the rotary shaft, the heavy hammer and the commutator segment are molded into a rotor by injection; the coil is arranged on an outer side face of the rotor, and electrically connected with the commutator segment; an electric brush and an FPC (Flexible Printed Circuit) are arranged in the lower bracket assembly; the rotor assembly is arranged on the lower bracket assembly through the rotary shaft; the electric brush is electrically connected with the FPC; the electric brush is in contact with the commutator segment; the shell assembly is arranged above the lower bracket assembly; the rotor assembly is arranged between the shell assembly and the lower bracket assembly; and the magnetic steel is arranged on the outer side of the coil. The flat vibration motor has the beneficial effects of long service life, high response speed, strong vibration sense, capability of providing a stable magnetic field, simple structure, convenience in operation and wide application range.

Description

technical field [0001] The invention relates to the related technical field of vibration motors, in particular to a flat vibration motor. Background technique [0002] The micro vibrating motor is a DC brushed motor. There is an eccentric wheel on the motor shaft. When the motor rotates, the center point of the eccentric wheel is not on the center of rotation of the motor, so that the motor is constantly out of balance, causing vibration due to inertia. . [0003] As a micro motor, small vibration motors are mainly used in small electronic products such as mobile phones and electric toys, especially smart phones. As the screens of smart phones are getting larger and larger, the weight of mobile phones is also getting heavier. At the same time, mobile phones have higher requirements for vibration touch, especially when playing games on mobile phones, the frequency of using the vibration function is also more. Heavier volume, faster response and better vibration touch, it is...
