Abstract:
1. A horn comprising: (a) a body; (b) a sound generating unit in the body; (c) at least two means for storing at least one electrical power source in said body; (d) at least one of said at least two means for storing being operatively engageable with at least one electrical power source upon an assembly therewith to power said sound generating unit, and wherein said body is configured with a handle so as to be hand-held, extending along a first direction and a casing extending along a second direction away from said first direction, at least one of said at least two means for storing being mounted in said handle and another of said at least two means for storing being mounted to said casing, thereby enabling an enhanced electrical power source storage capability of said horn; and (e) a central processing unit (CPU) mounted in said body and coupled to each of said at least two means for storing and to said sound generating unit, said CPU executing software operative to selectively couple each of said at least two means for storing to said sound generating unit to prevent discontinuity of an operation of said sound generating unit when a resource of one said at least two means for storing reaches a predetermined value.
