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 equalizerremoves a high range component which is difficult to be reproduced by a vibration speakerand is hard to be conveyed by bone conduction. Then, the vibration speakeroutputs the sound over a low range to a middle range by bone conduction sound. By equalizing processing of the first equalizer, it is also possible to reduce sound leakage of the high range. On the other hand, a second equalizerremoves components over the low range to the middle range. Then, an air conduction speakeroutputs high quality sound of the high range component by air conduction sound.
