发明名称 Writing utensil structure with plural whistles
摘要 A writing utensil structure includes a body having an upper end portion and a lower end portion defining a first sound emitting nozzle. A spacer is mounted in an inner wall of a mediate portion of the body for closing it, thereby defining an upper chamber and a lower chamber communicating with the first sound emitting nozzle. A first sound diffusing nozzle is defined through an outer wall of the lower end portion of the body and communicates between the lower chamber and the first sound emitting nozzle. A first sound guiding wedge is mounted in an inner wall of the lower end portion of the body and is located diametrically opposite to the first sound diffusing nozzle. By such an arrangement, the writing utensil structure can function as a whistle.
