Stereophonic device for a bed

摘要

A stereophonic device for a bed disposed adjacent to at least a wave reflecting object is provided. The bed has an upper side and a lower side. The stereophonic device includes a loudspeaker disposed on the lower side of the bed. The loudspeaker is adapted to generate direct sound waves radially propagating therefrom. A part of the direct sound waves propagate through the bed toward the upper side of the bed, and another part of the direct sound waves propagate toward the wave reflecting object, reflected by the wave reflecting object and becoming a reflected sound waves. The reflected sound waves then propagate toward the upper side of the bed and demonstrate stereophonic sound along with the direct sound waves propagating theretoward.
