Abstract
Abstract A bellows sounder is operated by both opening and closing a door on a toy building. The sounder comprises a vibrating reed actuated by the closing of the bellows, and a cam on the door and a follower on the toy are arranged for moving the follower on both opening and closing of the door to expand the bellows which then close under spring pressure to generate the sound.
