A device for diagnosing and treating hearing disorders including a supersonic transducer which has a resonance frequency in the supersonic range. The transducer includes a piezoelectric ceramic tube which is compressed between a head mass and an inertial mass. A tensioning rod extends between the masses and is threadedly engaged with a nut which tensions the rod to adjust the compression on the ceramic tube. A tuning circuit can be used to increase the band width at resonance.
Dispositif de diagnostic et de traitement de troubles auditifs, comprenant un transducteur supersonique dont la fréquence de résonance se situe dans la gamme des fréquences supersoniques. Le transducteur comprend un tube de céramique piézoélectrique comprimé entre une masse de tête et une masse d'inertie. Une tige de tension relie les masses et s'engage dans un écrou qui tend la tige de façon à adapter la compression du tube de céramique. Un circuit de réglage peut être utilisé afin d'accroître la largeur de bande au point de résonance.
