Abstract (en)
[origin: WO2007075674A2] A linear array acoustic transducer with multiple diaphragms arranged in one or more sets uses improved diaphragm designs that increase structural rigidity and acoustic efficiency. In one implementation, a single driving rod is used to drive multiple diaphragms in each set of diaphragms to reduce the number of diaphragm openings and mitigate adverse effects caused by air leakage through the openings. Improved methods of manufacture are also disclosed.
