Abstract
The implementations describe a method and a system to perform the method to reduce buzzing in a speaker by obtaining a signal having an audio content, determining a first value of spectral density of the audio content at a first resonance frequency, the first resonance frequency associated with a mechanical motion of at least one member of a speaker assembly, determining a second value of spectral density of the audio content at a second resonance frequency, the second resonance frequency associated with a port of the speaker assembly, determining, responsive to the first value and the second value, that the signal is to produce buzzing of the speaker at the second resonance frequency, producing a modified signal by limiting spectral density of the audio content at the first resonance frequency, and providing the modified signal to the speaker.
