A single port multi-resonator acoustic resonator device ( 200, 300, 400, 490 ) possesses an input impedance that exhibits precisely designed electrical resonances. The device contains at least three parts: a transducer/resonator ( 201, 301, 401. 491 ) used both to interface to an external electrical circuit and to transform electrical energy into mechanical (i.e. acoustic) vibrations (and vice versa), and also function as a resonator; a mechanical (i.e. acoustic) resonator ( 203, 303, 460, 480 ) and an acoustic coupler ( 202, 302, 404, 494 ) that controls the acoustic interaction between the transducer/resonator and the mechanical resonator.
