MEMS Loudspeaker with Position Sensor |
| 摘要 |
A MEMS loudspeaker for generating sound waves within an audible wavelength spectrum includes a circuit board, a membrane spaced from the circuit board and being deflectable along a z-axis, at least one piezoelectric actuator for deflecting the membrane, an electronic control unit embedded in the circuit board for controlling the at least one piezoelectric actuator, and at least one position sensor for providing to the control unit a sensor signal dependent on the deflection of the membrane, the control unit controlling the piezoelectric actuator based on the sensor signal. |

1. A MEMS loudspeaker for generating sound waves within an audible wavelength spectrum, the MEMS loudspeaker comprising:
a circuit board; a membrane spaced from the circuit board, the membrane being deflectable along a z-axis; at least one piezoelectric actuator for deflecting the membrane; an electronic control unit embedded in the circuit board for controlling the at least one piezoelectric actuator; and at least one position sensor for providing to the control unit a sensor signal dependent on the deflection of the membrane, the control unit controlling the piezoelectric actuator in a regulated way based on the sensor signal. |
