Abstract
A system for adjusting playing volume automatically according to ambient sound and a method for the same are provided. The system includes a volume sensing unit, a volume adjustment database, a time data unit, an audio frequency module, and a volume control unit. The volume sensing unit detects for a change of ambient sound and generates a sensing signal. The time data unit generates a current time data. The volume adjustment database is built-in and configured for storing an audio variation data. The audio frequency module receives or outputs an audio signal. The volume control unit retrieves the sensing signal, the audio variation data, and the current time data, adjusts the audio variation data according to the sensing signal, and controls variation of the audio signal outputted in real time, so as to enable automatic adjustment of playing volume and enchant audience.
