Claim 0:
1. A method for braking a linear resonance device, wherein
the linear resonance device comprises a linear resonance actuator and a driving chip, the driving chip pre-stores a driving waveform signal and a first braking waveform signal, and the method comprises:
in response to a braking instruction, determining whether a vibration of the linear resonance actuator under driving of the driving waveform signal meets a first condition;
in a case that the vibration of the linear resonance actuator meets the first condition, controlling the driving chip to output the first braking waveform signal to drive the linear resonance actuator to perform a first braking process on the linear resonance actuator;
and in a case that the first braking process meets a second condition, controlling the driving chip to stop outputting the first braking waveform signal, to finish braking the linear resonance actuator, wherein
the first braking waveform signal comprises at least two pulses, and among the at least two pulses, an amplitude of a preceding pulse is greater than an amplitude of a succeeding pulse.
