Method of generating 3d haptic feedback and associated handheld electronic device

Abstract

The present invention is directed to a method of generating three dimensional (3D) haptic feedback and an associated handheld electronic device. A first, a second and a third directional actuator groups are disposed on an inner surface of a housing. The vibration inertial forces generated by the first, the second, and the third directional actuator groups are parallel with the first, the second and the third axial directions respectively. The first, the second, and the third directional actuator groups are individually or in combination driven, thereby generating haptic feedback.

Description

technical field [0001] The invention relates to an actuator, in particular to a method for generating three-dimensional tactile perception feedback and a handheld electronic device. Background technique [0002] An actuator is an energy conversion element, such as converting electrical energy into mechanical energy, and further generating sound waves or haptic feedback. Actuators can be designed and implemented with smart materials, common smart materials such as piezoelectric materials (piezoelectric material), electro-active polymer (Electro-Active Polymer, EAP), shape memory alloy (Shape Memory Alloy, SMA) , Magnetostrictive Material, Electrostrictive Material, etc. [0003] The actuators of conventional electronic devices for tactile feedback are generally disposed on the lower surface of the screen. When the actuator is driven, the actuator can convert electrical energy into mechanical energy, so that the mechanical energy acts on the touch screen to generate vibratio...

AI Technical Summary

Problems solved by technology

However, the traditional tactile feedback electronic device can only generate vertical unidirectional vibration, so it cannot present diversified feedback control, thus limiting its application level

[0004] It can be seen that the above-mentioned existing tactile sensing feedback electronic device obviously still has inconveniences and defects in the tactile sensing feedback generation method, product structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned existing problems, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable method and structure for general methods and products to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
