The new NU Dolphin is a Waterproof MP3 player tailored for swimmers and water sports enthusiasts. The design concept is to create a portable & Waterproof music device that can be worn by swimmers and other water sport athletes while keeping the impact on their athletic performance to minimum. The NU design team come up with this ultra light weight, ultra compact player that weighs only 25g with a dimension of 60 × 20 × 20mm. Its cylindrical-shaped casing features a minimalist outlook with all control buttons located on one side, and the headphone jack on the other side. The Waterproof earphone attaches to the player via a special screw-in jack to keep the device water-tight.
Both the Waterproof earphone and the Waterproof MP3 player were tested to comply with IPx7 international water resistant standard. The Waterproof earphone employs a special non-woven fabric membrane to keep the speaker vibration plate dry while maintaining a high quality sound output. The earpieces are attached with a soft silicon earplug that fits snugly in the ears. The earplugs not only keep the earphones dry but also prevent the earphones from coming loose during vigorous activities.
Operating time for the NU Waterproof MP3 Dolphin is roughly 8 hours when fully charged, and recharging time is about 1.5 hours. Recharging (and file downloading) can be done via USB port.
Initial release of the NU Waterproof MP3 Dolphin is designed to be worn on swimmer goggles; there will also be an optional armband for surfing and other activities. Future plans for Waterproof MP3 Dolphin include accessory kits designed to provide better functionality for different water sports activities.
