Abstract (en)
[origin: WO2018215669A2] A micromechanical acoustic transducer comprises, according to a first aspect, a first bender transducer with a free end and a second bender transducer with a free end which are situated in a common plane, wherein the free end of the first bender transducer is separated from the free end of the second bender transducer by a gap. The second bender transducer is excited in phase to the vertical oscillation of the first bender transducer. A micromechanical acoustic transducer comprises, according to a second aspect, a first bender transducer which is excited vertically to the oscillation and a plate element which extends vertically relative to the first bender transducer and is separated from a free end of the first bender transducer by a gap.
