LEARNING MATERIAL FOR LEARNING THE PRINCIPLE OF A BOND CONDUCTIVE HEADPHONE, CAPABLE OF TRANSFERRING SOUND THROUGH BONES

摘要

PURPOSE: A learning material for learning the principle of a bond conductive headphone is provided to substantially learn with respect to acoustic sense by implementing a self experiment through a simple manipulation.;CONSTITUTION: A wood stick(11) is in contact with the body of a human and transfers sound waves through bones. A neodium magnet(13) is located at the end of the wood stick. The neodium magnet is surrounded by a compressive tube(12). An enamel wire(14) surrounds the circumference of the wood stick in which the neodium magnet is located. A plug jack(15) are in connection with both ends of the enamel wire.;COPYRIGHT KIPO 2011
