Abstract
A protective enclosure for an electronic device can include a waveguide to direct and enhance sound waves emanating from a speaker of an electronic device when installed in the protective enclosure. The waveguide can include a first end and a second end. The first end of the waveguide can be located proximate the speaker of the electronic device. The waveguide can increase in cross-sectional area between the first end and the second end. The second end of the waveguide can be located proximate a front surface of the protective enclosure and can direct sound waves toward a user of the electronic device.
