Acoustically Coupled Resonators: Filters and Pressure Transducers,
Abstract
Acoustical radiation is of particular intensity for resonators having large normal components of displacement. This can be used as a simple and efficient way to transfer energy between two resonators in order to constitute a filter structure. A one dimensional modelization of gas coupled extensional composite resonators is described. This model indicates a simple dependence of the response on several parameters of the gas gap. A theoretical investigation of vibrational and electrical behaviour of composite resonators and of acoustically coupled biresonator filters made by a bi or tridimensional finite element analysis is reported. This analysis was performed for two different types of structures: one of cylindrical geometry, the other of paralellipipedic geometry.
