Abstract
A double gong bell has an outer gong and an inner gong separately arranged to accommodate the inner gong within the space defined by the inner surface of the outer gong. In one embodiment at least two hammer driving members, disposed within the space defined by the inner surface of the outer gong and slidably supported within a mounting means are adapted for reciprocal movement upon the action of a hammer driving means. The ends of the hammer driving members closest to the gongs are attached to a first resilient member and a hammer. A pair of second resilient members attached to the hammer driving members and the mounting means are biased to urge the hammers to strike the inner and outer gongs upon the action of the hammer driving means generating a bell sound having composite tone colors.
