Mobile terminal and a sound pressure control method
First Claim
1. A sound pressure control method for a mobile terminal that has a target digital value of an adequate output sound pressure level at a maximum volume level, the method comprising:
- determining a digital value corresponding to a maximum output sound pressure level of an externally sourced audio material, wherein the externally sourced audio material is being replayed for a first time at a preset gain at the maximum volume level;
comparing the determined digital value with the target digital value;
adjusting, if the determined digital value is not equal to the target digital value, the gain so that a digital value corresponding to the adjusted gain is equal to the target digital value; and
storing the adjusted gain as a gain value associated with the maximum volume level for the externally sourced audio material.

Abstract
A mobile terminal and sound pressure control method using sound saturation sensing are disclosed. The mobile terminal has a target digital value of an adequate output sound pressure level at a maximum volume level. The sound pressure control method includes: determining a digital value corresponding to a maximum output sound pressure level of an externally sourced audio material, wherein the externally sourced audio material is being replayed for the first time at a preset gain at the maximum volume level; comparing the determined digital value with the target digital value; adjusting, if the determined digital value is not equal to the target digital value, the gain so that a digital value corresponding to the adjusted gain is equal to the target digital value; and storing the adjusted gain as a gain value associated with the maximum volume level for the externally sourced audio material.

13. A mobile terminal comprising:
-
a memory unit for storing a plurality of externally sourced audio materials, a target digital value of an adequate output sound pressure level at a maximum volume level for an externally sourced audio material, and a gain setting table for the stored externally sourced audio materials; an audio output unit for generating sounds with a preset gain at the maximum volume level for an externally sourced audio material selected for replay for a first time; a digital value producer for determining a digital value corresponding to a maximum output sound pressure level of the selected externally sourced audio material; a comparator for comparing the determined digital value with the target digital value; a gain adjuster for adjusting, if the determined digital value is not equal to the target digital value, the gain so that a digital value corresponding to the adjusted gain is equal to the target digital value; and a gain setter for storing the adjusted gain in the gain setting table as a gain value associated with the maximum volume level for the selected externally sourced audio material. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
