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.

Abstract: A handheld telephone set used by connecting a dual-ear mount type or single-ear mount type earphone that automatically sets an optimal signal level of an ambient sound according to the earphone type used, provided with: a telephone set main body unit, a detection device for detecting which type of earphone is mounted to the telephone set main body unit, an amplifier for amplifying the ambient sound to be delivered to the earphone, and a control device for controlling a signal level of the ambient sound output from the amplifier according to an output of the detection device. When either of these earphones is mounted, the control device controls the signal level of the ambient sound output from the amplifier to be fed back according to an output of the detection device.

Abstract: To automatically set an optimal signal level of an ambient sound according to earphone type even in the case where either of both-ear mount type and single-ear mount type earphones is mounted to a telephone set main body unit, and to recognize the ambient sound even in the case where a stereo headphone almost covering ears is used.
