    Abstract: A MEMS loudspeaker arrangement for generating sound waves in the audible wavelength spectrum includes a housing that defines a sound-conducting channel and a sound outlet arranged at the end of the sound-conducting channel. At least two MEMS loudspeakers are arranged in the interior of the housing so that they generate sound waves through the sound-conducting channel to the sound outlet. One of the MEMS loudspeakers is disposed downstream of the other in the direction of the sound outlet. A control unit is connected to control the MEMS loudspeakers so as to increase the maximum loudness of the MEMS loudspeaker arrangement. The first of the two MEMS loudspeakers is controlled to function as a sound generator for generating an initial wave, and the second MEMS loudspeaker is controlled to function as a sound amplifier for amplifying the initial wave.

    Abstract: The present invention relates to a sound transducer assembly (1) with a MEMS sound transducer (21) for generating and/or detecting sound waves in the audible wavelength spectrum, which comprises a first cavity (41), and an ASIC (11) electrically connected to the MEMS sound transducer. In accordance with the invention, the ASIC (11) is embedded in a first substrate (10), and the first MEMS sound transducer (21) is arranged in a second substrate (20). In addition, it is provided that the first substrate (10) and the second substrate (20) are electrically connected to one another, and that the first cavity (41) is at least partially formed in the first and/or second substrate (10, 20).

    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).

    Abstract: A loudspeaker arrangement for a plurality of MEMS loudspeakers for generating sound waves in the audible wavelength spectrum includes a housing, which has a sound conduction cavity and at least one sound outlet opening, and at least two MEMS loudspeakers, arranged in the interior of the housing opposite and spaced apart from each other by the sound conduction cavity. Each MEMS loudspeaker has a cavity in the region of their opposite faces. The loudspeaker arrangement includes a shielding wall for acoustically decoupling the two MEMS loudspeakers from each other. The shielding wall is arranged in the interior of the housing between the two MEMS loudspeakers such that the sound conduction cavity is subdivided into a first and a second a cavity region respectively associated with one of the two MEMS loudspeakers
