This is a protective enclosure for objects like electronic devices to protect them from environmental damage and mishandling. The enclosure has two halves that seal together to enclose the object inside fully. The halves are made of a shock-absorbing material that cushions impact. When sealed, the enclosure is waterproof to protect against liquids.

4. Customizable and Rugged Waterproof Enclosures for Electronic Devices

TREEFROG DEVELOPMENTS, INC., 2020

Modular device accessories allow users to customize and enhance their electronic devices like smartphones, tablets, and laptops for specific tasks, environments, and activities. The accessory consists of a protective enclosure covering the device and an adapter sealing the device's ports. The enclosure provides rugged protection from water, dust, and drops while maintaining touchscreen functionality. The adapter plugs into the device's ports to create sealed connections. This allows the device to be used in harsh conditions while preventing damage. Additional attachments like clips, mounts, and chargers can be added to the enclosure.

5. Waterproof and Shockproof Enclosure for Electronic Device Protection

Otter Products, LLC, 2019

A protective enclosure for encasing an object to protect it from adverse conditions, inclement weather, mishandling, and damage like contacting liquids. The enclosure has two or more portions that can be coupled together to form a waterproof seal and shockproof structure. The enclosure can be used to protect objects like electronic devices that are prone to damage from water and drops.

6. Dual-Function Protective Enclosure for Waterproof and Shockproof Device Protection

Otter Products, LLC, 2019

A protective enclosure for protecting electronic devices and other objects from damage due to water exposure and drops. The enclosure has two parts that can be coupled together to form a waterproof seal and a shockproof structure.

7. Advanced Waterproof Enclosures for Electronic Devices with Functional Feature Preservation

Otter Products, LLC, 2019

Protective enclosures for electronic devices like smartphones that protect against water damage without sacrificing functionality. The enclosures have features like a sealing membrane over the audio ports, blocking water penetration while allowing sound transmission. Other features include a curved seal around the camera flash to distribute light uniformly, a camera lens insert, and a sealed window over the touchscreen.

8. Waterproof Case with Sound Transmission and Device Interaction Features

CATALYST LIFESTYLE LIMITED, 2019

This waterproof case for electronic devices maintains water and air tightness while allowing device interaction and sound transmission. The case has a main housing and lid joined with a compression gasket. Features like stabilization structures, slots, ports, and buttons allow device actuation while sealed. The case interior traps air that vibrates membranes in response to sound pressure, transmitting audio.

9. Waterproof Cases with Interactive Features for Electronic Devices

CATALYST LIFESTYLE LIMITED, 2018

Waterproof, sealed cases for electronic devices. The cases have slots, ports, and membranes that allow interaction with the device while protecting it from water.

10. Waterproof Electronic Enclosure with Improved Vent Design for Water Drainage

ALPS ELECTRIC CO., LTD., 2018

This is a waterproof enclosure for electronics with an improved vent design that allows attached water to be easily removed. The enclosure has an outer shell with a penetrating hole covered by a waterproof filter and a projecting part covering the hole.
