ABSTRACT:
It is the object of the invention to provide a compact and highly stable head-mount image display apparatus capable of always transmitting voice information of an optimal volume, irrespective of the positional relationship between the head and the ear of an observer, which is related to the shape and/or size of the head. To attain the object, speakers incorporated in the apparatus of the invention can be moved to desired positions in accordance with changes in the positional relationship between the head and the ears of observers. Further, the apparatus of the invention can be folded to reduce the area the apparatus occupies.
