MOBILE APPARATUS AND CONTROL METHOD THEREOF
First Claim
1. An apparatus comprising:
- a housing forming at least part of a surface of the apparatus, the housing including an opening formed thereon;
interface circuitry adapted to receive an audio signal;
a first filter adapted to adjust the audio signal to produce a first audio signal corresponding to a first frequency band;
a second filter adapted to adjust the audio signal to produce a second audio signal corresponding to a second frequency band;
a dynamic driver located in the housing and adapted to output the first audio signal via the opening; and
a balanced armature driver located in the housing and adapted to output the second audio signal via the opening.

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.
