Zusammenfassung:	A linear resonant device and a braking method for the same. The linear resonant device comprises a linear resonant motor (100) and a drive chip (200). The drive chip (200) pre-stores a drive waveform and at least one first braking waveform therein. The method comprises: determining, in response to a braking instruction, whether vibration of the linear resonant motor (100) meets a first condition while being driven by the drive waveform; and if so, controlling the drive chip (200) to drive, by using the first braking waveform, the linear resonant motor (100) and to conduct a first braking process for the linear resonant motor (100), wherein the first braking waveform comprises at least two pulse waveforms, and an amplitude value of each of the at least two pulse waveforms gradually decreases along a propagation direction of the first braking waveform, such that vibration damping is achieved according to a current vibration amplitude of the linear resonant motor (100), thereby realizing fast and effective braking.
