Claim 11:
12. The linear resonance device according to claim 10, wherein the first braking waveform signal comprises a first pulse and a second pulse, wherein
the driving chip being configured to output the first braking waveform signal to drive the linear resonance actuator comprises the driving chip being configured 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.
