Apparatus and method for controlling operation of audio low sound output means

A method for operating an audio device in or coupled to a portable system, comprising:

• identifying a file type being currently executed in the system;
• selectively disabling a lower sound audio output device of a plurality of audio output devices in or coupled to the system under a first condition that is based on identification of the file type as a text file type;
• and
• disabling the lower sound audio output device under a second condition that corresponds to when a current power source is a battery, the lower sound audio output device disabled when the current power source is a battery irrespective of a text file type to be executed in the system.

A method for operating an audio device in or coupled to a portable system, comprising:

• setting an enable/disable status of a low sound audio output device based on text file type, wherein information corresponding to the enable/disable status is set in a table stored in advance in a memory of the portable system;
• identifying a file type of a file to be currently executed;
• determining an enable/disable status of the identified file based on said information in the table;
• and
• disabling an operation of the low sound audio output device when the identified file type corresponds to the text file type and said information in the table corresponding to the text file type indicates that the enable/disable status is disable, wherein:
• the low sound audio output device is one of a plurality of audio output devices having different characteristics, and an audio signal of a high-pass component and an audio signal of a low-pass component in connection with a low sound audio output are separately output from a CODEC to the audio output devices, and
• disabling operation of the low sound audio output device when a current power source of the system is a battery, operation of the lower sound audio output device disabled when the current power source is a battery irrespective of a text file type to be executed by the system.

A method for operating an audio device in or coupled to a portable system, comprising:

• determining an enable/disable audio command responsive to at least one of a plurality of audio information of audio to be output, wherein the enable/disable command is set in a table stored in advance in a memory of the portable system;
• identifying said at least one of audio information of a file being currently executed;
• determining the enable/disable audio command corresponding to the identified file;
• and
• disabling an operation of the low sound audio output device when the determined enable/disable command is disable, wherein the low sound audio output device is one of a plurality of audio output devices having different characteristics in an audio device and wherein the identified file is a text file, said method further comprising:
• disabling operation of the low sound audio output device when a current power source of the system is a battery, operation of the lower sound audio output device disabled when the current power source is a battery irrespective of a text file type to be executed by the system.
