摘要:
The resonator comprises a first electrode (E1), a second electrode (E2) and a piezoelectric layer (P) arranged between the above. A first acoustic compression layer (V1) is arranged between the piezoelectric layer (E1) and the first electrode (E1) with a higher acoustic impedance than the first electrode (E1).
