A Japanese company Tuesday unveiled a new device that will allow people "speak" through their ear so they can use their mobile telephones in noisy places.
The device -- named "e-Mimi-kun" (good ear boy) -- doubles as an earphone and a microphone by detecting air vibrations inside the ear, developer NS-ELEX Co. said.
The earpiece and an accompanying device can be connected to a mobile phone, or wirelessly to a Bluetooth handset, so that users no longer have to cover their mouths when speaking in a loud environment, the company said.
Exterior noise is reduced six-fold by the earpiece, it said, while a chip developed by Sanyo Electric for the accompanying device reduces sound levels ten-fold, it added.
NS-ELEX believes the product would be useful for people working in places such as factories, restaurants and amusement parks.
