| 摘要 |
The present invention relates to speaker systems and, more particularly, to a network audio speaker system, in which a speaker management system compresses and transmits original audio signals to be reproduced and control signals, and a speaker system, assigned an IP address, decompresses the received signals and reproduces the signals as original MP3 sound, so that only a single UTP (CAT5) cable is used, thus simplifying the line structure, facilitating maintenance, and preventing noise from occurring, and, so that individual or group automatic broadcasting control is possible, thus improving efficiency in emergency broadcasting in case of emergency. |
