PURPOSE:To attain the sense of locality and to listen to stereosonic sound felt by the entire human body by making the direction of vibration of an oscillating signal nearly vertical to a floor, and guiding the said oscillating signal in a direction to the front of the human body and irradiating it so as to enclose the human body. CONSTITUTION:The vibrating direction of sound waves is made vertical to the floor by fitting a speaker having a diaphragm 8 vibrated in floating to the upper face of a box 7 upward, and the waves are reflected in the inner face of a 1/4 spherical shell 10 covered on the diaphragm to guide them in the front direction 11 to the listener. Three speakers 12, 13, 14 are arranged to the listener 3 in this embodiment and the speaker 13 sends the sound in the direction of the listener 3 by using reflecting plate 15 in the upward direction 9. On the other hand, the sound from the speakers 12, 14 flows around a face 17 including the speaker 12, 14 and ears 4, 5, the sound of the speakers 12, 13, 14 flows so as to enclose the human body 3 truly three-dimensionally. |
