Abstract
A system for adjusting playing volume according to a predetermined time and a method for the same are provided. The system includes a time data unit, a volume adjustment database, a volume control unit, and an audio frequency module. The time data unit generates a current time data. The volume adjustment database is built-in and configured to store an audio variation data. The audio frequency module receives and outputs an audio frequency signal. By reference to the current time data and the audio variation data, the volume control unit adjusts variation of the audio frequency signal outputted in real time, thereby enchanting audience and enhancing delivery of advertisement messages.
Claims10
A system for adjusting playing volume according to a predetermined time, comprising:
- a time data unit for generating a current time data;
- a volume adjustment database being built-in and configured for storing an audio variation data;
- an audio frequency module for receiving and outputting an audio frequency signal;
- and
- a volume control unit for adjusting variation of the audio frequency signal outputted in real time according to the current time data and the audio variation data.
A method for adjusting playing volume according to a predetermined time, comprising the steps of:
- retrieving, by a volume control unit, a current time data generated by a time data unit and an audio variation data stored in a volume adjustment database, respectively;
- determining, by the volume control unit and according to a result of computation performed on the current time data and the audio variation data, whether playing volume should be currently adjusted, and generating a control signal;
- and
- controlling, by the volume control unit and according to the control signal, variation of an audio frequency signal outputted by an audio frequency module in real time.
