Better Sound From Your Cell Phone

A new system that uses tissue conduction to carry sounds promises to make cell phones audible virtually anywhere. Smart Sonic Receiver technology uses a piezo-electric actuator to create vibrations across a smart phone's display screen. These vibrations are transmitted to the skin, tissue - and ultimately the eardrum - resulting in clearer voice quality.

Current Bluetooth headsets that use bone conduction to supplement a phone's speaker tend to produce muffled sound because they bypass the eardrum. The new method works regardless of where the ear is placed on the screen, and also helps to block outside sounds by acting as a shield.
