Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

The vibrating motor with the built-in vibrator 4 provided by the embodiment, as shown in fig. 1 to 3, includes a casing 1, a rotor assembly and a stator assembly 3 both disposed in the casing 1, and further includes a vibrator 4, wherein the vibrator 4 is fixedly mounted on the stator assembly 3.

Specifically, stator module 3 is the coil, and the shape of oscillator 4 can select the arc sheet structure as shown in fig. 1 to 3 to can laminate the coil setting, the effect of eccentric vibration can be realized as long as oscillator 4 of this embodiment is fixed in the side of coil. Traditional eccentric wheel needs to be installed on rotor frame 6 (pivot promptly) of rotor subassembly, and the eccentric wheel has certain height, consequently can lengthen vibrating motor's length on the whole, and the oscillator 4 of this embodiment, the laminating is on the coil, compares in traditional oscillator 4 (eccentric wheel promptly) the setting, can not lengthen vibrating motor's total length to still set up in casing 1, consequently also can not influence vibrating motor's waterproof function's setting, has higher practicality.

In the vibration motor with the built-in vibrator 4 provided by the embodiment, as shown in fig. 1 to 3, the casing 1 is provided with the end cover 2, the end cover 2 is provided with the rotating cavity, the end cover bearing 5 is assembled in the rotating cavity, and the rotor assembly is connected with the end cover bearing 5. The rotor assembly comprises a rotor frame 6, a commutator 7, a magnetic ring 8, a bushing 9 and a stator bearing 10, wherein the commutator 7 is installed on the rotor frame 6, the bushing 9 is sleeved on the periphery of the rotor frame 6, the magnetic ring 8 is sleeved on the periphery of the bushing 9, the stator assembly 3 is sleeved on the periphery of the magnetic ring 8, an axial cavity is formed in the bushing 9, the stator bearing 10 is assembled in the axial cavity, one end of the rotor frame 6 is inserted into the stator bearing 10, the other end of the rotor frame 6 is inserted into the end cover bearing 5, and a gap is reserved between the stator bearing 10 and the two ends of the rotor frame 6 and between the end cover bearing 5 and the two ends of the rotor frame 6 respectively.

Specifically, as shown in fig. 1 to fig. 3, which are schematic views of an assembly structure of the casing 1, the end cover 2 and the rotor assembly, the coil rotates under the action of the magnetic field to drive the vibrator 4 to rotate, and the commutator 7 is also installed on the coil, so that the rotor frame 6 is also driven to rotate by the rotation of the coil, and the rotation is kept in one direction to continuously rotate under the action of the commutator 7, which is the prior art and is not described herein again. The rotation of the stator assembly 3 and the rotor assembly operates the vibration motor, and the vibrator 4 may vibrate the vibration motor.

Further, an arc-shaped ball 11 is convexly arranged at the other end of the rotor frame 6, and the arc-shaped ball 11 is in contact with the end cover 2, so that the contact between the rotor frame 6 and the end cover 2 is smoother.
