Abstract

PURPOSE:To obtain the natural feeling of site similar to the speaker reception, by locating sound body at the focus of the parabola of the audio reflector having parabola surface, and converting the audio waves reflected at the parabola surface for the sound from the sound source into plane waves. CONSTITUTION:The U-shaped support rods 10, 10' are fixed to the ring shape ear guides 9, 9' supported with the head phone band 8, and the audio reflectors 6, 6' are located at the support rods 10, 10', and the sound body 7, 7' are located with the rods 11, 11' at the focus of the parabola surface of the reflectors 6, 6'. Further, when the head phone unit is mounted on the ears 2, 2' of the listner 1, the angle theta between the reflector 6 and the front of the listner 1 is taken as 0-60 deg., and the diameter of the aperture of the reflector 6 and the distance to the ear are selected to optimum location, the sound from the front is listened as plane waves to obtain natural feeling of site the same as the case with the reception by speakers.
