发明名称 Piezoelectric transducer device
摘要 The present invention relates to a transducer device (10), comprising: an acoustic membrane (14); a piezoelectric element (12) mounted to the acoustic membrane; two oppositely arranged elastic damping elements (16a, 16b) between which a peripheral portion (22) of the acoustic membrane is sandwichably supported; and a clamp (28) having two surfaces (30a, 30b) between which the two elastic damping elements are clamped so that the two elastic damping elements are pressed together, whereby the peripheral portion of the acoustic membrane is secured between the two elastic damping elements. The present invention also relates to a method of assembling such a transducer device.
