An electromechanical device includes a piezoelectric support delimited by a surface, or by two surfaces parallel to each other, and, on this support, a resonator for elastic waves propagating parallel to the surface or surfaces, the resonator including two reflectors that delimit the resonator and which are reflective for the waves, several interfacing transducers, to generate the waves from an electrical signal, and several transducers for controlling the resonance frequency, each transducer including a first electrode and a second electrode that are interdigitated, the transducers being arranged along the propagation path followed by the waves in the resonator, with, along the path, an alternation between interfacing transducer and tuning transducer.
