Abstract

The present invention is a multi-source powered audio playback system which integrates multiple energy charging sources that charge an internal battery, with a digital audio player and an analog audio amplifier and multiple audio outputs. In one embodiment, the present invention includes a mechanical power generating means, rectifier, solar power cell, blocking circuit, external AC/DC charger, blocking circuit, charge control circuit, at least one rechargeable battery pack, a power control circuit, a digital audio player, at least one mass memory device with secure content, voltage regulator circuit, power supply de-coupling circuit, analog audio amplifier, output circuit and a waterproof speaker. The audio content is secured by the elimination of a consumer usable data port and/or password protection. The invention optimally provides an audio output signal that is sufficient for private, room or group use.
