    In this study, we propose a device that can output high-frequency signals without touching the vibration source by using sound, and to improve the problem of reduced output in the low-frequency band, which is a characteristic of a speaker, I use amplitude modulation to reproduce low-frequency waves from high-frequency waves. I conducted pressure measurements to validate the amplitude modulation. The results confirmed that the modulated waves were output correctly and that the modulation increased the output in the low frequency band.
