Abstract
A mobile apparatus and control method thereof are provided, which includes an audio data signal input unit arranged to receive an audio data signal. An audio output unit is arranged to output an audio signal according to the received audio data signal within a first reproduction frequency. A balanced armature is arranged to output an audio signal according to the received audio data signal within a second reproduction frequency band. The second reproduction frequency band is different from the first reproduction frequency band. An audio signal processor is arranged to adjust the first reproduction frequency band and the second reproduction frequency band such that a combination of the first reproduction frequency band and the second reproduction frequency band is wider than the first reproduction frequency band and the second reproduction frequency band individually.
