1. A speaker system for a mobile device comprising:
- a first audio processing unit and a first speaker for reproducing an audio signal and outputting the reproduced audio signal, wherein the first speaker is embedded in a main body of the mobile device;
a second audio processing unit and a second speaker for reproducing the audio signal and outputting another reproduced audio signal;
a first battery embedded within the main body and a second battery within a battery module releasably connected to the main body, wherein the second speaker is embedded in the battery module;
a controller positioned in the mobile device and configured to perform operations comprising;
determining if the battery module is connected to the mobile device;
in response to a determination that the battery module is not connected to the mobile device, controlling the first audio processing unit to transfer the audio signal to the first speaker and controlling the second audio processing unit not to transfer the audio signal to the second speaker; and
in response to a determination that the battery module is connected to the mobile device, controlling the first audio processing unit to transfer the audio signal to the first speaker and controlling the second audio processing unit to transfer the audio signal to the second speaker.

14. A method of controlling a speaker system for a mobile device, comprising:
-
determining if a battery module having an embedded speaker is operatively connected with the mobile device, the mobile device having a first speaker and a first battery embedded within a main body of the mobile device, the battery module being releasably connected to the main body;
the battery module having a second battery; andcontrolling, by a controller positioned in the mobile device, an operation mode of first and second audio signal processing units based on the determination of whether the battery module is operatively connected with the mobile device, the controlling comprising; in response to a determination that the battery module is not connected to the mobile device, controlling the first audio processing unit to transfer the audio signal to the first speaker and controlling the second audio processing unit not to transfer the audio signal to the embedded speaker; and in response to a determination that the battery module is connected to the mobile device, controlling the first audio processing unit to transfer the audio signal to the first speaker and controlling the second audio processing unit to transfer the audio signal to the embedded speaker; and transmitting the audio signal from the mobile device to the embedded speaker in the battery module. - View Dependent Claims (15, 16, 17, 18, 19)
