Powerbank Regulator For PoE Loudspeakers
(2024)Department of Automatic Control
- Abstract
- This master’s thesis project explores the development and implementation of a powerbank for Power over Ethernet (PoE) driven loudspeakers, addressing the inherent limitations of output power imposed by PoE Type 1. PoE, while advantageous for simplifying installations and reducing wiring costs, restricts the maximum power delivery to connected devices. This constraint poses significant challenges for audio applications, particularly in handling high amplitude peaks without causing clipping and distortion.
To overcome these limitations, the thesis introduces an innovative solution involving a supplementary powerbank added to the loudspeaker’s amplifier. The powerbank is intended to provide additional power during peak audio demands,...

PoE, while advantageous for simplifying installations and reducing wiring costs, restricts the maximum power delivery to connected devices. This constraint poses significant challenges for audio applications, particularly in handling high amplitude peaks without causing clipping and distortion.
To overcome these limitations, the thesis introduces an innovative solution involving a supplementary powerbank added to the loudspeaker’s amplifier. The powerbank is intended to provide additional power during peak audio demands, ensuring consistent and high-quality sound output. A critical component of this system is the Power multiplexer (MUX), which intelligently selects the power source, either the PoE or the powerbank, based on real-time analysis of the audio input.
An algorithm developed for the Power MUX monitors the audio signal, predicting power needs and seamlessly switching to the powerbank when the input data indicates potential clipping or power insufficiency. This adaptive power management strategy not only mitigates the limitations of PoE but also enhances the overall performance and reliability of PoE-driven loudspeakers.
The prototype and testing demonstrate the effectiveness of this approach, highlighting its potential in various environments where high-clarity audio and simplified installation are paramount. This thesis contributes to the advancement of PoE technology in audio systems, offering a viable solution to extend the capacity of PoE-driven loudspeakers beyond their conventional power constraints.
