Abstract:
The invention relates to a MEMS sound transducer, in particular a MEMS loudspeaker and/or a MEMS microphone, for generating and/or detecting sound waves in the audible wavelength spectrum, with a support element ( 9 ), a membrane ( 2 ) deflectable with respect to the support element ( 9 ) along a z-axis, at least one piezoelectric actuator ( 7 ) supported on the support element ( 9 ) for deflecting the membrane ( 2 ) and one electronic control unit ( 11 ) for driving the actuator ( 7 ). In accordance with the invention, the MEMS sound transducer features at least one position sensor ( 19 ), by means of which the control unit ( 11 ) can provide a sensor signal ( 37 ) that is dependent on the membrane deflection. Furthermore, the control unit ( 11 ) is designed such that, for the functional self-test, for distortion reduction, for damage protection and/or for the compensation of behavioral changes, the sensor signal can be analyzed and/or can be reconciled with a reference signal ( 8 ) stored in the control unit ( 11 ), and that the actuator ( 7 ) can be driven in a controlled manner by taking into account the analysis result ( 35 ) and/or the comparison result ( 34 ).

Claim (Index 1):
MEMS sound transducer for generating and/or detecting sound waves in the audible wavelength spectrum, comprising:\n a support element, a membrane deflectable with respect to the support element along a z-axis, at least one piezoelectric actuator supported on the support element and disposed for deflecting the membrane when the one piezoelectric actuator becomes driven, one electronic control unit disposed for driving the actuator and at least one position sensor connected to the control unit and configured to provide to the one electronic control unit a sensor signal that is dependent on the membrane deflection, wherein the control unit is configured for performing a functional self-test process a distortion reduction process, a damage protection process and/or a compensation process for the compensation of behavioral changes, wherein the control unit is configured to analyze the sensor signal to obtain an analysis result and drive the actuator in a controlled manner in accordance with the analysis result and/or configured to reconcile the sensor signal to obtain a comparison result with a reference signal stored in the control unit and drives drive the actuator in a controlled manner in accordance with the comparison result.
