A novel fire control and extinguishing method intended for a Fire Suppression System. This system can be mounted statically, deployed from a vehicle, or incorporated into a complete unmanned vehicle (autonomous or remotely operated) using an electrical system or thermoacoustic means to generate acoustic waves to accomplish fire control and/or fire suppression. This approach eliminates the need for a vehicle to carry chemical flame retardants/extinguishers, or other traditional fire combating means, resulting in an impactful environmental footprint reduction and a marked specific efficiency improvement. The acoustic wave is generated through thermoacoustic or mechanical means using a linear actuator of magnet-and-coil, piezoelectric, or magnetostrictive construction and operating near mechanical, electrical, and acoustic resonance to reduce system power and mass.

A diaphragm for a piezoelectric micromachined ultrasonic transducer (PMUT) is presented having resonance frequency and bandwidth characteristics which are decoupled from one another into independent variables. Portions of at least the piezoelectric material layer and backside electrode layer are removed in a selected pattern to form structures, such as ribs, in the diaphragm which retains stiffness while reducing overall mass. The patterned structure can be formed by additive, or subtractive, fabrication processes.
