Improvements in a light speaker are disclosed where power to the light speaker is provided by the Ethernet connection. The light speaker module is connected to the Ethernet such that power to the fan is from a portion of the power to the Ethernet is stolen or otherwise parasitically harvested. Depending upon the available Ethernet power, the fan can be powered directly, or from a storage supply such as a battery. The speed of the fan can also be adjusted based on a local temperature sensor. Measuring a local temperature provides the best indicator for when air movement and air volume is needed. The temperature sensor can be located on a specific device, housing or in the air around the fan. Fan speed and the temperature to be communicated to other devices or a host over the Ethernet or to a cloud-based application or database.
