Abstract: An amplification device amplifies sound waves that emit from a portable electronic device. The portable electronic device joins the amplification device at a horizontal orientation that is efficacious for watching videos in wide screen format. A slot in the amplifying device engages a speaker in the portable electronic device. The amplifying device receives sound waves generated by the speaker at a narrow, speaker receiving end, passes the sound waves through an acoustic channel, and finally emits the sound waves from a wide, amplifying end. Increasing surface area at the wide end of the amplifying device lowers the acoustic impedance, and consequently amplifies the sound waves. The sound waves amplify because acoustic impedance is lowered and matched to the proximate air. A cone-shaped dispersion port positions within the acoustic channel to optimize sound wave dispersion. A housing contains the components and has a sloped surface for supporting chargers.
