发明名称 Megaphone cup
摘要 A new megaphone cup for providing a device that is convertible between a drinking cup and a megaphone. The inventive device includes a base having upper and lower surfaces with a tubular cup mount upwardly extending from the upper surface of the base. The cup mount has a lumen and an upper opening into the lumen. Removably inserted into the lumen is the bottom end of a cup member. The top and bottom ends of the cup member both have openings into the cup member hollow interior and the cup member is also tapered towards the bottom end of the cup member. When the cup member is detached from the cup mount, a user may shout into the opening of the bottom end to use the cup member as a megaphone. The cup member also includes an extendable portion which is retractably extendable between an extended position and a retracted position.
