Light-emitting-diode (#LED#) system and method for illuminating a cover for a portable electronic device commensurate with sound or vibration emitted therefrom

A cover system for covering a portable electronic device may include: a protective cover that covers the portable electronic device, the protective cover having: an assembly energized by an electrical signal, the assembly being removably coupled with the protective cover; and an electronic panel fixedly coupled with the assembly and the protective cover, the electronic panel having: a microphone that detects a sound and/or a vibration emitted by the portable electronic device to generate a communication signal indicative thereof; a plurality of light-emitting-diodes (LEDs) embedded in the electronic panel; a plug powering the plurality of LEDs; and an integrated circuit that generates the electrical signal to activate the plurality of LEDs in response to receipt of the communication signal from the microphone to cause the LEDs to produce a luminescence proportionate to and commensurate with an intensity and/or a rhythm of the sound and/or the vibration.
