Abstract

The present disclosure discloses a feeding apparatus, which includes a motor, a driving unit, and a noise reduction module. The noise reduction module includes an audio receiving unit and a control unit. The audio receiving unit receives the sound generated by the feeding apparatus when the motor is running. The control unit is electronically connected to the driving unit and the audio receiving unit. The control unit sequentially supplies a plurality of motor drive data to the driving unit to drive the motor to run. The control unit sequentially receives a plurality of sound signals corresponding to those motor drive data from the audio receiving unit. The control unit analyzes the sound signals and selects one of the sound signals as an optimized sound signal. The control unit stores the motor drive data corresponding to the optimized sound signal as a setting motor drive data.
