Check out Kyocera’s Urbano Progresso smartphone. It works in a very, very interesting way. It transmits sound directly through connective tissue and into your inner-ear rather than through your ear canal. It’s done through some sort of vibrations transmitted through the screen.
In the end, this means that you can hear sound through the phone even if you are in a noisy environment, because it’s playing in your head, which sounds crazy, but it seems to work pretty well according to the videos and reports by those who had a chance to test it out. It also means that it is great for hearing impaired users.
The handset runs Ice Cream Sandwich, and has a 4-inch WVGA OLED screen and 8MP camera. The processor is a dual-core Snapdragon MSM8655 clocked at 1.4GHz.
