Electronic device comprising piezoelectric device, and touch input detection method using piezoelectric device

Abstract

At least one processor, individually and/or collectively, of an electronic device, according to various embodiments of the present disclosure, may be configured to: if communicatively connected to an external electronic device through a short-range communication circuit in a state where a piezoelectric element and an audio output circuit are electrically connected, control at least one switching circuit so that the piezoelectric element and a touch sensing circuit are electrically connected; if a touch input is detected in the piezoelectric element through the touch sensing circuit, control the at least one switching circuit so that the piezoelectric element and the audio output circuit are electrically connected, and output audio through the audio output circuit; and after outputting the audio, control the at least one switching circuit so that the piezoelectric element and the touch sensing circuit are electrically connected.
