Title:
SOUND REPRODUCING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/168903
Kind Code:
A1
Abstract:
Provided is an earhole open-type sound reproducing device with which it is possible to obtain satisfactory sound quality across a wide bandwidth while employing bone conduction. A first equalizer 303 removes a high-frequency component which is difficult to reproduce using a vibrating speaker 301 and which is not readily transmitted by bone conduction. Sound ranging from a low-frequency region to a medium-frequency region is then output by means of bone-conducted sound from the vibrating speaker 301. The equalizing process performed by the first equalizer 303 also reduces leakage of sound in the high-frequency region. Meanwhile, a second equalizer 304 removes components ranging from the low-frequency region to the medium-frequency region. High quality high-frequency component sound is then output by means of air-conducted sound from an air-conduction speaker 302.
