Abstract

The invention provides a portable audio amplifying apparatus for an MP3 player, particularly various IPOD™ models, and any other portable handheld multimedia device, which comprises a receptacle, a connecting means, an amplifier means, at least one audio speakers and a power source means. The receptacle is made up of a door assembly and a lock plate assembly operatively linked to accommodate all existing MP3 players or portable handheld multimedia devices that are smaller than the original IPOD™ player while allowing easy access to the control units during playback. Sliding the multimedia device into the receptacle and closing the door locks the device into place to ensure extremely secure compartment. The connecting means is made up of a finger grasp, an input plug, a spring mechanism and a cable connector. Furthermore, the unique design of the finger grasp allows easy movements of large fingers within limited space of the receptacle.
