Abstract
The present invention prevents a three-dimensional fabric arranged in front surfaces of speakers from flapping due to sound. In the respective front surface sides of, sound-emitting direction regulating members that include annular portions that project forward by a predetermined distance are arranged. A three-dimensional fabric is tensioned and arranged so as to cover the front surface sides of the sound-emitting direction regulating members. When the three-dimensional fabric is pressed against the annular portions configuring the sound-emitting direction regulating members, the annular portions bite into the three-dimensional fabric since the three-dimensional fabric has a predetermined thickness. The annular portions are provided so as to surround diaphragms of the speakers. Sound output from the speakers passes inside the annular portions. However, the periphery of a region of the three-dimensional fabric in which sound passes is supported by the biting of the annular portions, thereby preventing the three-dimensional fabric from flapping widely in response to the sound.
