摘要： In one aspect, a sound transducer unit includes at least two magnet units having a permanent magnetic field and further includes at least two acoustic units. Each acoustic unit has a diaphragm that is deflectable along a stroke axis for generating sound waves. The sound transducer unit also includes a coil arrangement provided in association with each acoustic unit, wherein the coil arrangement is configured to be supplied electric current such that the diaphragm is deflectable along the stroke axis. The at least two magnet units and the at least two acoustic units are arranged alternatively one above the other.

摘要： A MEMS sound transducer for generating and/or detecting sound waves includes a support having a cavity wall which at least partially delimits a cavity of the MEMS sound transducer. At least one cantilever arm element includes a base section that is fixedly connected to the support. Each cantilever arm includes a flexible deflection section overhanging the cavity wall. At one end of the deflection portion is a base end that is disposed to face the cavity wall. Opposite the base end is a free end that is configured to be deflectable relative to the support in the direction of a stroke axis of the MEMS sound transducer. The base end of the deflection section in a sound transducer top view has a curved first contour.
