SPEAKER BOX, TV RECEIVER AND ITS REAR COVER

摘要

PROBLEM TO BE SOLVED: To inexpensively provide a speaker box with excellent sound quality, by which standing wave or specified wave generated between two parallel wall surfaces is efficiently reduced. SOLUTION: As against standing wave or specified wave generated between the two parallel wall surfaces, a first reflection board 15 which is adjacent to the wall surface 11a at the opposite side of a speaker 13 and is provided with an opening 14 at one end or both ends is arranged with inclination to the wall surface 11a. A plurality of second reflection boards 16a and 16b are disposed in a vertical direction, for example, so as to be crossed with the wall surface 11a in order to form a nearly Z shape in the first reflection board 15.
