PURPOSE: To obtain a speaker device by which the excellent stereo sound field reproduction can be realized. CONSTITUTION: By arranging three diaphragms 6a to 6c and voice coils 8a to 8c in line in a horizontal direction on frames 4 and adding the synthetic signals (L-R), (L+R) and (R-L) of a stereo signal to each voice coils 8a to 8c, the sound fields 7a to 7c to be created by the sound waves radiated from each diaphram 6a to 6c are acoustically synthesized. Because the stereo sound fields 7d and 7e are created by normally positioning the L and R signals on the external side of a listener 3, a stereo reproduction can be easily realized by saving space, even if the stereo reproducing device installing two conventional speakers with a constant spacing is not used. |
