Abstract

Die Erfindung betrifft einen Ultraschallwandler mit einer zur Schwingung anregbaren Membran, die eine dünn ausgebildete und längliche Membranfläche umfasst, und mit wenigstens einem auf der Membranfläche angeordneten Piezoschwinger.The invention relates to an ultrasonic transducer with a vibration-excitable membrane which comprises a thin and elongated membrane surface, and with at least one arranged on the membrane surface piezoelectric oscillator.

Die Erfindung kennzeichnet sich dadurch, dass die Membranfläche an ihren Längsseiten jeweils wenigstens eine Einschnürung aufweist.

Figure imgaf001
The invention is characterized in that the membrane surface has at least one constriction on its longitudinal sides.
