发明名称 Ear Speaker Device
摘要 The ear speaker device includes a mount section that is provided with ear-hook sections, and rotation sections that rotate speaker movable sections with respect to the mount section. Tubular ducts are positioned more inside than the ear-hook sections in a natural state. When the ear speaker device is mounted, the speaker movable sections are rotated to the most outside positions. Then, the ear-hook sections are brought into contact with auricle base upper sections, respectively, and the speaker movable sections are rotated inwardly. In this manner, the tubular ducts can be positioned in the vicinity of the external acoustic meatus openings, respectively, of the listener without interfering with auricles and the like.
