Audio output enhancement algorithms for piezoelectric loudspeakers
Leung Kin Chiu, David V. Anderson, Benjamin Hoomes · 2011
Piezoelectric loudspeakers have a small form factor and are suitable for electronic devices that have a thin profile. However, they have poor frequency response, especially in low frequencies. This paper introduces a method that combines psychoacoustic bass extension and sub-band dynamic range compression to make the audio sound “richer” in piezoelectric speakers. Subjective test results are also presented.
