发明名称 TOY RACKET WITH SOUND RESONATING MEMBRANE
摘要 <p>A toy games racket is provided with a sound resonating membrane. The racket (58) has an inner frame (45) held within an outer frame (70), and the inner frame (45) has a striking surface in the form of a tympanum (54) stretched tautly across the inner frame (45) in a manner so as to apply a preselected degree of tension to the tympanum. The tympanum is formed of a flexible, transparent plastic film (55) held within the inner frame (45) by a drum-head assembly having an outer hoop member (46) and an inner ring member (56), thereby forming a sound-reverberating and resonating ball impact surface. The outer frame (70) of the racket (58) has a handle (59) which extends outwardly from the frame (70), and the outer frame (70) may include opposing frame halves (60, 62) which engage each other by way of interlocking members (38).</p>
