Claim 9:
10. A linear resonance device, comprising:
a linear resonance actuator;
a driving chip; and
a processor, wherein
the driving chip is configured to pre-store a driving waveform signal and a first braking waveform signal; and
the processor is configured to:
in response to a braking instruction, determine 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, control 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, control 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.
