| 摘要 |
This portable sound speaker system has an elongated cylinder supporting a layer of acoustically absorbent material lining the interior surface thereof. The cylinder has an open, raised platform as its support in a vertical position, where the platform has a first base plate carrying a plurality of spacers on which is fastened a second plate having a large central hole open to the interior of the cylinder to allow the bass sound to radiate radially outward therefrom. A first, low frequency loudspeaker is fitted down into the upper end of the cylinder, and it radiates upwardly. A second, high frequency loudspeaker is mounted above the first loudspeaker, and it radiates in a generally horizontal direction. A cylindrical speaker grille is fitted over the second loudspeaker and mounted to the top end of the cylinder.
