Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] It should be noted that, in the dual-frequency bidirectional micro linear vibrator in the embodiment of the present invention, high frequency and low frequency are relative terms, and various frequency ranges can be obtained by changing the width or material thickness of the shrapnel. At the same time, the relative positions of the high-fre...

Abstract

The invention discloses a dual-frequency bidirectional micro linear vibrator. The vibrator includes a supporting body, a flexible printed circuit, a coil, a limiting piece, a shielding block, a magnet, a balancing weight, a high-frequency elastic piece, a bracket, a positioning plate, a low-frequency welding piece and a high-frequency welding piece. A dual-frequency bidirectional structure is adopted, has two fixed vibration frequencies, two vibration directions and can provide high-frequency and low-frequency tactile feedback. When a driving mode combining high frequency with low frequency isadopted, additional tactile feedback experience can be obtained. By adjusting the mixing proportion of the high frequency and low frequency, diversified tactile feedback can be obtained, and more experience is provided for users.

Description

technical field [0001] The invention relates to the field of vibrators, in particular to a miniature linear vibrator with two natural oscillation frequencies and two vibration directions formed by a vibrator and a support body. Background technique [0002] Most of the traditional miniature vibrators used for tactile feedback are realized by the vibration generated by the rotation of the eccentric wheel driven by the DC motor; since the DC motor uses brushes for commutation, its life is limited by the brushes, and it is difficult to break through 200 hours. [0003] However, although there is a miniature brushless motor vibrator that can solve the problem of lifespan, its application is limited due to the long start-up time and slow response speed and feedback delay. [0004] At present, most linear vibrators developed using the principle of linear motors work at a single frequency, and the single-frequency tactile feedback mode can no longer meet the needs of diverse tactil...
