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.

Abstract: A protective case for a personal electronic device can include a compartment configured to receive and store an item such as, for example, a credit card, identification card, SIM card, memory card, keys, cosmetics, or cash. The compartment can be a waterproof compartment designed to protect the contents of the compartment from damage in situations where the protective case is exposed to liquids. In some examples, the compartment can include or be configured to receive and store cosmetics, cosmetic tools, or a mirror, and can eliminate the need to carry a separate compact. In some examples, the compartment can include an ejection mechanism configured to eject a credit or identification card from the compartment.

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.
