Patent ID: 11482202

Abstract:
An apparatus comprises a circuitry and an acoustic-capture tile having a surface that is to face an acoustic source that is to emit a first acoustic wave having a first frequency and a second acoustic wave having a second frequency. The acoustic-capture tile comprises a first acoustic-capture subtile electrically coupled to the circuitry, the first acoustic-capture subtile to resonate at the first frequency, wherein the first acoustic-capture subtile is to capture the first acoustic wave and to convert the first acoustic wave into a first electric current in response to resonance at the first frequency. The acoustic-capture tile also comprises a second acoustic-capture subtile electrically coupled to the circuitry, the second acoustic-capture subtile to resonate at the second frequency, wherein the second acoustic-capture subtile is to capture the second acoustic wave and to convert the second acoustic wave into a second electric current in response to resonance at the second frequency.
