Power-over-ethernet multichannel streaming audio amplifier
The granted patent US12047040B2 describes a power-over-Ethernet (PoE) powered multichannel streaming audio amplifier designed to receive both power and audio data through multiple Ethernet ports. Each port is capable of connecting to an Ethernet cable, allowing for the transmission of power and high-resolution digital audio streams, such as those from online music services. The amplifier's power supply circuitry incorporates a Field-Effect Rectifier Diode and multiple PoE controllers, which work together to manage and combine the power received from the Ethernet connections. The system is designed to automatically identify available power levels from connected power sourcing equipment, such as PoE-enabled network routers, and can handle up to 90 Watts of power per port, adhering to the IEEE 802.3bt standard.
The amplifier's architecture includes isolation transformers to block direct current while permitting alternating current to pass, along with rectifier bridges that convert this alternating current into direct current. The power supply circuitry is further enhanced by a DC-DC converter that adjusts the voltage levels for the microprocessor subsystem and the digital audio amplifier, providing 5 VDC and 24 VDC outputs, respectively. The design allows for a flexible configuration of audio outputs, ranging from 4 to 8 channels, and integrates all components into a compact housing. The patent outlines a method for operating the amplifier, detailing the steps for receiving power and audio data, processing the audio signals, and amplifying them for output to connected speaker devices.
