Abstract
The cellular telephone case comprises a sound deflector, a heat conducting sheet, a plurality of vent apertures, one or more bumpers, and an ear rest. The case fits onto a cellular telephone. The sound deflector may increase the audio volume of a cell phone by deflecting sound energy to the front of the phone. The ear rest may increase the comfort when using the cell phone. The heat conducting sheet and the plurality of vent apertures may enhance the cooling of the cell phone by spreading the heat over a larger surface area and by allowing air to carry the heat away. The one or more bumpers may enhance the cooling of the cell phone and increase the audio volume by creating a gap between the rear of the phone case and the surface upon which the phone has been laid.
