Technology
The bone conduction
mechanism is already applied to some telephone sets, but the existing
technology asks the listener to put his ear over the receiver hard because it
vibrates the whole telephone set. Rohm developed a technology to allow the
listener to hear the voice on the mobile phone clearly using the bone
conduction mechanism in alliance with Professor Hiroshi Hosoi of Nara Medical University.
It helps the
listener hear the voice on the mobile phone clearer than a speaker system does
even if disturbing noise surrounds him. When the listener has difficulty
hearing the voice on the mobile phone, he can hear the voice clearly if he
presses the edge of his mobile phone, in which an element that vibrates with
voltage is incorporated, on his ear when surrounding noise prevents him from
hearing the voice clearly. The company plans to market the technology to mobile
phone and smartphone manufacturers both at home and abroad.
