Abstract
Abstract A speaker headrest is composed of a frame and a concave front surface to support the user's head through a cushion and members flanking the frame and rotatably attached thereto. Speakers contained in these flanking members are pressed against the user's ears when the user's head is moved backward to rest against the frame, thereby pushing lever plates attached to the flanking members backwards and causing the flanking members to rotate around their supporting axes of rotation.
