Lever-type haptic feedback device

Abstract

A lever-type haptic feedback device. A longitudinal extension of the laminate piezoelectric ceramics is carryed out once so as to drive the swing end to swing upward through the driving end of the lever-type elastic transmission member so as to drive the mass block to directly impact the inner top surface of the shell, and the mass block moves downward under the elastic action of the lever-type elastic transmission member and the rebound force after the impact until the mass block directly strikes the bottom surface of the shell, then the mass is restored to the initial state by the elastic action of the lever-type elastic transmission member and the rebound force after the impact, and the laminated piezoelectric ceramics are longitudinally retracted to the initial state during the upwardmovement of the mass. The whole device is simple in structure and good in technicality, which is advantageous to the effective propagation of vibration. The vibration amplitude of laminated piezoelectric ceramics can be amplified by using lever-type elastic transmission parts, and the problem of small vibration amplitude of existing vibrators is solved.

Description

Technical field [0001] The invention relates to a lever type tactile feedback device. Background technique [0002] At present, in our daily life, in order to increase the user experience of products, many product manufacturers have added tactile feedback devices that provide tactile confirmation to their products, such as mobile phone call vibration reminders, electronic touch screens and other functions, which improve the use of products. The operability and simplicity of the process facilitate user identification. [0003] Traditional tactile feedback devices generally use vibration motors based on electromagnetic induction effects. Their complex structure leads to complex production processes and slow response speeds, making it difficult for products to have a good user experience. [0004] Although a tactile feedback vibrator with piezoelectric ceramics as the vibration source appears on the market, the structure is complex, and the transmission distance of the piezoelectric ce...

AI Technical Summary

Problems solved by technology

[0003] Traditional tactile feedback devices generally use vibration motors based on electromagnetic induction effects. Their complex structures lead to complex production processes and slow response speeds, making it difficult for products to have an excellent user experience.

[0004] Although the tactile feedback vibrator with piezoelectric ceramics as the vibration source has appeared on the market, the structure is complex, and the transmission distance from the piezoelectric ceramics to the mass block is long, and the mass block indirectly hits the shell, resulting in large energy loss and small amplitude. The vibration effect felt by the human body is not obvious
