ABSTRACT:
A piezoelectric capsule with resilient conducting holding means is disclosed, comprising a hollow metal lid (8) fitted on a base body (7) formed of a printed circuit, and a piezoelectric membrane (1) applied against a front step (17) of the lid (8). A resilient electrically conducting element (22), fixed to the base body (7), bears on the metallized external rear face (5) of the piezoelectric ceramic layer (3) of the membrane (1). The resilient element (22) provides simultaneously electric conduction and mechanical holding of the membrane (1) in position.
