Japanese mobile phone provider KDDI has introduced a mobile phone today that uses bone-conduction technology, targeted for the Japanese market. Previously, phones using this technology were only aimed at construction site workers who needed to use their mobile phone in noisy environments.

I had also written a post about an underwater mp3 player just last month that uses the same bone-conduction technology to deliver sound via cheekbones.

More of how the phone works and specs after the jump.

The KDDI A1407PT from handphone makers Pantech works by propagating sound waves through the user’s bone to the eardrum directly instead of using the conventional method of projecting sound waves to the ear through the air filled with ambient noises. This results in a clear signal and allows the user to hear sounds much clearer.

All the user needs to do is to press the handphone’s speaker behind or under the ear, to make use of bone-conduction to listen to a conversation.

The phone comes with 2.4-inch lcd screen, 1.2 inch sub-display, a 1.3-megapixel camera, 200-minute talk time and weighs in at 120 grams.

Pricing for the phone is at 20,000 Yen which is about SGD$251.00. It’s only for the Japanese market currently, but such a technology certainly comes in handy for people who work or live in noisy environments so I hope handphones similar to this will enter the Singapore market too.
