Abstract: An electronic device (10) such as a mobile phone, a cellular phone, a two-way radio, a laptop computer, a portable stereo receiver, a portable television, or any combination thereof can include a cover such as a battery door cover (14) having a predetermined thickness and an aperture (16) within the battery door cover serving as an audio port for the electronic device and further constructed to serve as a bottle cap opener. The aperture can be for a high audio port (11) on a speaker phone for example. The aperture can be formed substantially towards an end portion of the battery door cover. The battery door cover can also be made of a rigid material such as plastic, metal or carbon fiber composite and can further include a sharp edge (17) to serve as a cutting instrument. Optionally, the battery door can further include a retractable or removable blade (19).
