摘要：
An oscillation device includes a first oscillator (120), a second oscillator (112), and a control unit (50). The first oscillator (120) includes a first piezoelectric vibrator, and the second oscillator (112) includes a second piezoelectric vibrator. The control unit (50) inputs an audio signal of an audible sound to the first piezoelectric vibrator included in the first oscillator (120), and inputs a modulation signal of a parametric speaker to the second piezoelectric vibrator included in the second oscillator (112).
