Problems solved by technology
[0002] The Chinese invention patent No. 200520130124.8 discloses Ethernet remote power supply equipment, including signal lines, power lines for power supply systems, output connection lines for power amplifier speakers, network lines, and other types of signal lines that often require pre-embedded processing. There are many types, different distances, and the influence of human factors in the pre-embedded construction process, which will lead to technical problems such as a high probability of failure and difficult noise control in the final sound reinforcement system debugging. The power cord and the hardware configuration cost of the system will remain high

The invention discloses a digital power amplification system of an Ethernet power source electricity network, comprising a signal receiving module, a network transmission module, a signal processing module and a transmitting module. The signal receiving module is electrically connected with the network transmission module, and the signal processing module is electrically connected with the transmitting module. The system further comprises a power supply module electrically connected with the signal receiving module, and the network transmission module and the signal processing module are respectively in electrical connection with the signal receiving module, thus, the function of both transmitting audio signals and supplying power for the overall unit by one network line is realized, and the problem of noise interference caused by an analogue signal long-distance transmission line is overcome effectively.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a network digital power amplifier system powered by Ethernet power supply. Background technique [0002] The Chinese invention patent No. 200520130124.8 discloses Ethernet remote power supply equipment, including signal lines, power lines for power supply systems, output connection lines for power amplifier speakers, network lines, and other types of signal lines that often require pre-embedded processing. There are many types, different distances, and the influence of human factors in the pre-embedded construction process, which will lead to technical problems such as a high probability of failure and difficult noise control in the final sound reinforcement system debugging. The cost of the power cord and the hardware configuration of the system will also remain high. Contents of the invention [0003] Aiming at the shortcomings in the prior art, the present inv...
