Title:
TACTILE VIBRATION CONTROL SYSTEM AND METHOD FOR SMART TERMINAL
Document Type and Number:
WIPO Patent Application WO/2017/113652
Kind Code:
A1
Abstract:
Provided are a tactile vibration control system and method for a smart terminal, said system comprising a command generator (11), a filter (12), a tactile driver (13), and a linear resonant actuator (14); the command generator (11) generates an original command signal according to an input signal; the filter (12) filters the original command signal, and after filtering, the magnitude of the initial predetermined number of pulses is larger than a predetermined threshold and the phase of the predetermined number of pulses of the extremity reverses; according to the filtered command signal, the tactile driver (13) generates a drive signal to drive the linear resonant actuator (14) to vibrate. In the system, the original command signal generated by the command generator (11) is filtered by means of the filter (12), such that when a subsequently generated drive signal is used to drive the linear resonant actuator (14) to vibrate, the linear resonant actuator (14) is able to rapidly dynamically respond as well as respond by braking, weakening the extent of overlap of the vibration events before and after the short interval in the time dimension, thereby increasing the degree of distinction in time dimension between the vibration events and ensuring that a desired effect is achieved.
