Lobe to joy?

As Beethoven's hearing declined, the composer devised a way to hear music through his jawbone by biting onto a rod attached to his piano. This effect, know as bone/tissue conduction, is being put to good effect by Japanese mobile telephone manufacturer Kyocera to help overcome difficulties in hearing due to high ambient noise. Kyocera's phone display vibrates to create sound waves that are transmitted to your inner ear when you press the phone on your ear. In essence, the phone itself acts like a low powered speaker, but instead of a membrane, it is the actual screen that vibrates to emit sound waves. The sound waves then travel through your ear and skin by tissue conduction to reach the cochlea.
