Abstract
Provided is a resonator. The resonator includes: at least one air cavity and a plurality of air passages communicating with the air cavity. The air cavity and the plurality of air passages are tuned to generate one or more acoustic resonances. Therefore, the desired low acoustic damping can be reasonably well maintained, while distributing higher modes over a wider set of frequencies, while also making each of them proportionally weaker. Thus, they may be more easily made weak enough not to interfere with the desired behaviour of the overall acoustic resonator construction.
