Feeding apparatus and noise reduction module and method thereof

A noise reduction module applied to a feeding apparatus, the feeding apparatus comprising a motor and a driving unit, the driving unit driving the motor to run, the noise reduction module comprising:

• an audio receiving unit receiving the sound generated by the feeding apparatus as the motor is running;
• and
• a control unit electrically connected to the driving unit and the audio receiving unit, wherein 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;
• and the motor drive data corresponding to the optimized sound signal is stored as a setting motor drive data.

A noise reduction method applied to a feeding apparatus, the feeding apparatus comprising a motor, a driving unit, and a noise reduction module;

• the driving unit driving the motor to run;
• the noise reduction module comprising an audio receiving unit and a control unit;
• the noise reduction method comprising the following steps:
• the control unit suppling a plurality of motor drive data to the driving unit to drive the motor to run;
• the audio receiving unit receiving the sound generated by the feeding apparatus as the motor is running, and sequentially generating a plurality of sound signals corresponding to those motor drive data respectively;
• the control unit sequentially receiving the sound signals from the audio receiving unit;
• the control unit analyzing the sound signals and selecting one of the sound signals as an optimized sound signal;
• and
• the control unit storing the motor drive data corresponding to the optimized sound signal as a setting motor drive data.
