Abstract
A mobile computing device includes a digital signal processor, a first speaker having a first sensitivity and a second speaker having a second sensitivity, where the second sensitivity is greater than the first sensitivity. The digital signal processor includes an audio signal manager that is configured to receive an audio signal having first and second channel signals, partition the first channel signal into a first high frequency signal and a first low frequency signal, partition the second channel signal into a second high frequency signal and a second low frequency signal, generate a mono low frequency signal based on the first and second low frequency signals, partition the mono low frequency signal into first and second mono low frequency signals based on an excursion limit of the second speaker, generate a first composite channel signal based on the first high frequency signal and the first mono low frequency signal for playback by the first speaker, and generate a second composite channel signal based on the second high frequency signal and the second mono low frequency signal for playback by the second speaker.
