Abstract

See full text

An electro-acoustic device includes a plurality of suspended, piezoelectric, acoustically waveguiding membranes supported in a common plane. An input transducer coupled to one of the waveguiding membranes converts input electrical signals to traveling-wave acoustic signals. An output transducer coupled to one of the waveguiding membranes converts acoustic signals to electrical signals. At least two of the waveguiding membrane have parallel straight sections that are longer than a guided acoustic wavelength and that are mutually separated by an air gap having a width less than the guided acoustic wavelength.
