  • Patent number: 4990816
    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.
    Type: Grant

  • Patent number: 4978880
    Abstract: A piezoelectric capsule with flat supporting surface and resilient 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). The resilient holding means (22), fixed to the base body (7), bear on the central zone of the rear face (5) of the membrane (1). The resilient means (22) hodl the membrane (1) mechanically in position and simultaneously provide peripheral sealing by the fact that the corresponding surfaces of the front step (17) and of the membrane (1) are perfectly flat.

  • Patent number: 4947075
    Abstract: A piezoelectric insert is provided comprising a membrane (1) formed from a substrate (2) and two piezoelectric material layers (3, 4) whose external surfaces are metallized so as to form the electrodes (5, 6). The membrane comprises a radial excrescence (15) whose upper and lower faces are nipped between the clip shaped legs of connectors (22, 23). The electric connection of the electrodes thus requires no soldering.

  • Patent number: 4944017
    Abstract: The present invention provides an insert (1) forming an independent assembly of a coil body (15). The electroacoustic transducer comprises an insert (1) formed of a case with a vibrating membrane (2) and its electric connectors (4, 5) and a coil body (15) distinct and separable from the insert. The coil body can be fitted to the rear face (14) of the insert and comprises axial passages (20, 21) through which the insert connectors (4, 5) pass. Contact pieces (22, 23) provide the electric connection of the coil with the insert connectors.
