Original Abstract Submitted
An acoustic device includes an acoustic MEMS device. An acoustic path communicates with the acoustic MEMS device. Ultrasound generated by vibration of the acoustic MEMS device can resonate in the acoustic path. An ultrasonic transducer has sound pressure frequency characteristics such that sound pressure peaks occur as a result of a combination of resonance of the acoustic MEMS device and resonance in the acoustic path. A relationship of about 5≤(f−fl)/f×100≤about 33 is satisfied, where f represents a resonance frequency of the acoustic MEMS device and fl represents a frequency lower than the resonance frequency and closest to the resonance frequency among frequencies at which the sound pressure peaks occur in the sound pressure frequency characteristics.
