Claim 1:
2. The method according to claim 1, wherein the first braking waveform signal comprises a first pulse and a second pulse, wherein
the controlling the driving chip to output the first braking waveform signal to drive the linear resonance actuator comprises: controlling the driving chip to output the first pulse prior to the second pulse;
and an amplitude AMP(i) of the first pulse and an amplitude AMP(i+1) of the second pulse meet the following equation:

AMP(i+1)=floor(N*AMP(i)/2m);

wherein i represents an integer not less than 1, N represents a pulse amplitude attenuation factor, m represents the number of bits of the pulse amplitude attenuation factor stored in a register, and a floor function is a ROUNDDOWN function.
