Title:
SIGNAL PROCESSING DEVICE HAVING MULTIPLE ACOUSTIC-ELECTRIC TRANSDUCERS
Document Type and Number:
WIPO Patent Application WO/2020/051786
Kind Code:
A1
Abstract:
A device for processing an audio signal (205) may include a first acoustic-electric transducer (211) and a second acoustic-electric transducer (212). The first acoustic-electric transducer (211) may have a first frequency response, and may be configured to detect the audio signal (205) and generate a first sub-band signal (2151) according to the detected audio signal (205). The second acoustic-electric transducer (212) may have a second frequency response, the second frequency response being different from the first frequency response. The second acoustic-electric transducer (212) may be configured to detect the audio signal (205) and generate a second sub-band signal (2152) according to the detected audio signal (205).
