Document Type and Number:
WIPO Patent Application WO/2004/043114
Kind Code:
A1
Abstract:
The system consists of the sound box, the digital audio frequency processor, the audio frequency amplifier, the sound source, also including the storage medium and the reader of the storage medium as the characters of the system. The characteristic parameters and the desired characteristics are described in the digital form and stored in the storage medium. The storage medium is put in the reader, which is positioned in the digital audio frequency processor. Based on the characteristic parameters and the desired characteristics stored and described in the storage, the digital audio frequency processor modifies the frequency signal sent from the sound source, and through the audio frequency amplifier drives the sound box, in order to get the desired output of the sound. The invention is designed reasonably, which can improve the quality of the sound and enables the acoustic to obtain the desired output of the sound.
