ABSTRACT:
An electronic device having a piezoelectric pump. The electronic device includes: an audio input section; an audio recording section recording input sound from the audio input section; a piezoelectric pump cooling air by a piezoelectric element; a drive circuit driving the piezoelectric element; and a control circuit monitoring and controlling operation of the audio input section, the audio recording section, and the drive circuit, wherein when an operation mode being monitored is an audio recording mode, in which the input sound is used for recording by the audio recording section, the control circuit controls the drive circuit to decrease the amount of air flow exhausted outside from the piezoelectric pump, and when the operation mode being monitored is another mode without audio recording, the control circuit maintains the amount of the air flow.
