An electro-acoustic transducer comprises a piezoelectric element (5) arranged on a transformer (6) and a membrane (1). The two ends of the transformer (6) facing away from the piezoelectric element (5) are connected on the one hand to the membrane (1) and on the other hand with a support (3). The transducer is characterized in that the membrane makes an angle with the transformer at the jonction between the two. This arrangement of the transducer and the piezoelectric element with respect to the support and the membrane makes it possible to achieve the full vibration capacity of the surface of the piezoelectric module and to eliminate resonance amplifications typical of piezoelectric elements, by using very small membranes. |
