Abstract (en)
[origin: WO2022180161A1] A MEMS acoustic transducer array (10*) comprises at least two acoustic transducers (12, 13, 14), a first acoustic transducer (14) of the at least two acoustic transducers being designed to reproduce an amplitude characteristic of a first resonant frequency, and a second acoustic transducer (12) of the at least two acoustic transducers being designed to reproduce an amplitude characteristic of a second resonant frequency. The second resonant frequency is higher than the first resonant frequency. The second acoustic transducer has a quality factor Q ≥ 1 or ≥ 3.
