ABSTRACT:
A lightweight miniature mobile communication unit allows the user to listen sufficiently and talk quietly in a noisy place so that the user can make a call without disturbing nearby people in the crowd. The mobile communication unit uses a bone conduction speaker (1) separated from the main body (2) instead of a built-in speaker or an external earphone.
