==ULTRASONIC TRANSDUCER - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18651723 titled 'ULTRASONIC TRANSDUCER

An acoustic device described in the patent application includes an acoustic MEMS device that can generate ultrasound through vibration. This ultrasound resonates in an acoustic path connected to the MEMS device. The device also features an ultrasonic transducer with specific sound pressure frequency characteristics that lead to sound pressure peaks due to resonance of the MEMS device and the acoustic path.

* The acoustic device incorporates an acoustic MEMS device capable of generating ultrasound.
* Ultrasound is produced through vibration of the MEMS device and resonates in the acoustic path.
* An ultrasonic transducer with unique sound pressure frequency characteristics is utilized.

==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.
