Vibration measuring head for medical examination of middle ear has electromechanical transducer with oscillating element supporting measuring head needle applied to part of inner ear

摘要

The oscillating element supports a measuring head needle (6) pressed against part (7) of the middle ear, which bends when the maximum application force is reached, the second winding supplying a signal representing the detected movement of the contacted part of the middle ear. The vibration measuring head has an electromechanical transducer (1) operated at its resonance frequency, with an oscillating element (4,4') having a coil with 2 windings (2.2') respectively coupled to a LF generator (9) and an evaluation device (10).
