<p>A speaker enclosure includes a first chamber (5) and a second chamber (6) separated by a partition (4) having an opening to which a speaker (7) is fitted. The partition is made of a member capable of flexural vibration and/or is supported on the inner surface of the enclosure through a flexible member (10) and is equipped with through-holes (9) permitting the passage of air between the first and second chambers (5,6). When the speaker (7) is driven, the partition vibrates with the vibration of cone paper (8) of the speaker, and a sufficiently strong bass sound can be generated as if the diameter of the speaker were expanded, and clarity of the sound can be improved. Since the through-holes are formed in the partition thus vibrated, the vibration effect of the partition can further be improved, and a sound pressure generated by the vibration of the partition is further improved by the contraction effect of the through-holes. As a result, the sound felt by the body through the vibration of the outer wall of the container has sufficiently high clarity particularly in strong bass low sound. <IMAGE></p> |
