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 speakers 20, 30, sound-emitting direction regulating members 23, 33 that include annular portions 231, 331 that project forward by a predetermined distance are arranged. A three-dimensional fabric 421 is tensioned and arranged so as to cover the front surface sides of the sound-emitting direction regulating members 23, 33. When the three-dimensional fabric 421 is pressed against the annular portions 231, 331 configuring the sound-emitting direction regulating members 23, 33, the annular portions 231, 331 bite into the three-dimensional fabric 421 since the three-dimensional fabric 421 has a predetermined thickness. The annular portions 231, 331 are provided so as to surround diaphragms 221, 321 of the speakers 20, 30. Sound output from the speakers 20, 30 passes inside the annular portions 231, 331. However, the periphery of a region of the three-dimensional fabric 421 in which sound passes is supported by the biting of the annular portions 231, 331, thereby preventing the three-dimensional fabric 421 from flapping widely in response to the sound.
