Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second"...

Abstract

The invention discloses a vibration motor, the vibration motor has a first direction and a second direction which intersect with each other, the vibration motor comprises a shell, a first vibration system and a second vibration system, and the shell has the first direction and the second direction which intersect with each other; the first vibration system is installed in the shell in a vibration mode in the first direction, the first vibration system comprises a vibration shell and two magnetic sets, and the two magnetic sets are both arranged in the vibration shell and fixed to the two ends of the vibration shell respectively; the second vibration system is installed in the vibration shell in a vibration mode in the second direction. The second vibration system comprises a frame arranged in the vibration shell, an iron core installed in the frame and a coil annularly arranged on the iron core in a sleeving mode. The two ends of the iron core are arranged corresponding to the two magnetic groups respectively. According to the invention, two sets of vibration systems can be obtained in a single vibration motor by utilizing two principles of the moving coil and the moving magnet, so that repeated arrangement of the vibrator and the stator is avoided, the structural design can be simplified, the mass can be reduced, and the size can be reduced.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a vibration motor. Background technique [0002] With the development of science and technology, various electronic device products have entered people's work and life. As a core component of tactile feedback in consumer electronics, electromagnetic vibration actuators are used in an increasingly wide range of applications. The electromagnetic vibration exciter is a kind of vibration motor. With the advancement of technology, a vibration motor that can realize two-way vibration appears on the market. This vibration motor usually includes a stator and a vibrator. The vibrator and the stator form a vibration system. [0003] In order to transmit more tactile information, dual-frequency bi-directional vibration actuators have been paid more and more attention. The dual-frequency two-way vibration exciter is a vibration motor that can realize two-way vibration. In rela...
