ABSTRACT:
A speaker system suppresses standing waves generated in the system and reproduces clear and dynamic bass sound. The system includes a cabinet formed of acoustic insulation walls, and at least one partition wall situated inside the cabinet to form a space by surrounding the space. The partition wall suppresses the standing waves generated inside the cabinet and is formed of a material having high internal loss.delete-start id="DEL-S-00001" date="20061010" ?The space has a total capacity more than one tenth of a capacity of the cabinet, wherein a closed end of the partition wall is located between one-half and four-fifths of a distance from one end to the other end, and an opening area of the same partition wall is located at a side opposite to the closed end in a longitudinal direction of the cabinet. The opening area is located between four-fifths and five fifths of a distance from one end to the other end.delete-end id="DEL-S-00001" ?insert-start id="INS-S-00001" date="20061010" ?The material has a density per volume greater than 0.1 g/cm3, a density per area from 0.01 g/cm2to 0.21 g/cm2and a characteristic of semi-transmission for the standing waves. The partition wall has a closed end portion. The closed end portion is formed of at least one of the partition wall and the acoustic isolation walls. The space is a substantially closed spaceinsert-end id="INS-S-00001" ?.
