PURPOSE:To provide a head phone with less positional deviation between the video and the sound image when a voice is listened together with the video in the head phone of localizing the sound image outside the head. CONSTITUTION:The outside localizing head phone device with the sound image localized outside the head updates the signal processing contents in the signal processor according to the rotation angle of the head of a listener 21. When the rotation angle calculated by the microprocessor is within the angle returnable range 24, the device is returned to the front direction angle (0 deg.) at a prescribed speed corresponding to the angle concerned. By preventing the return of the device in the case of an angle non-returnable range 23, when a deviation occurs between the result of rotation angle calculation and the actual head part rotation angle due to the integral arithmetic error, the deviation can be reduced. |
