Intelligent handheld equipment and resonant frequency measurement method for linear motor therefor

The embodiment of the invention discloses intelligent handheld equipment and a resonant frequency measurement method for a linear motor therefor. The intelligent handheld equipment comprises the linear motor, an acceleration sensor chip, and a drive chip. The method comprises the steps: employing the drive chip, taking a first frequency as the start frequency, taking a second frequency as an end frequency, taking a preset frequency as the interval, sequentially providing drive signals at all frequency points for the linear motor, and obtaining the measurement data of the acceleration sensor chip at all frequency points; obtaining the maximum measurement value of the measurement data of the acceleration sensor chip and a frequency point corresponding to the maximum measurement value based on the frequency points; and determining the frequency point corresponding to the maximum measurement value as the resonant frequency of the linear motor. The resonant frequency of the linear motor islocated in the range from
