Abstract:
Provided is an ear-hole open type sound reproducing apparatus which can obtain good sound quality over a wide band while adopting a bone conduction system. A first equalizer 303 removes a high range component which is difficult to be reproduced by a vibration speaker 301 and is hard to be conveyed by bone conduction. Then, the vibration speaker 301 outputs the sound over a low range to a middle range by bone conduction sound. By equalizing processing of the first equalizer 303, it is also possible to reduce sound leakage of the high range. On the other hand, a second equalizer 304 removes components over the low range to the middle range. Then, an air conduction speaker 302 outputs high quality sound of the high range component by air conduction sound.
