Claim Text:
1. An acoustic volume wave resonator configured to resonate at a predetermined work frequency comprising: a mounting, comprising a first surface and a second surface, formed by a layer, with a first thickness (s a resonating substrate, comprising a first surface and a second surface, made up of at least one layer, with a second thickness (t a diaphragm, made up of a layer, with a third thickness (m characterized in that the mounting comprises an internal cavity emerging on the second surface of the mounting, having a floor surface situated withdrawn in the direction of the thickness of the mounting relative to the second surface of the mounting, and a planar metal internal electrode, deposited on the floor surface, so as to form a gap area between the internal electrode and a portion of the diaphragm positioned across from it, and in that the resonating substrate is configured by the choice of said second thickness (t
