Abstract:
A method and apparatus increase audio output of a device. A mode of audio output operation of a device can be determined. Audio output can operate in a determined first mode of audio output operation that powers at least one first speaker at a first bandwidth and at a first output level below a first output level threshold. The audio output can operate in a determined second mode of audio output operation. The second mode of audio output operation can power the at least one first speaker at a high pass filtered second bandwidth that filters out low frequencies of the first bandwidth. The second mode of audio output operation can power the at least one first speaker at a second output level below a second output level threshold. The second output level threshold can be higher than the first output level threshold. The second output level can exceed the first output level threshold at least once. The second mode of audio output operation can power at least one second speaker at a low pass filtered second speaker bandwidth that includes at least the low frequencies of the first bandwidth.
