| 释义 |
The Clapper is a sound-activated electrical switch,[1] sold by San Francisco, California based Joseph Enterprises, Inc. Robert E. Clapper, Sr., and Richard J. Pirong marketed the clapper with the slogan "Clap On! Clap Off! The Clapper!".[2] The Clapper plugs into a U.S.-type electrical outlet, and allows control of up to two devices plugged into the Clapper.[3] An upgraded model, known as the Clapper Plus, includes a remote control function in addition to the original sound-based activation.[4] Although meant to activate by clapping, The Clapper can inadvertently be triggered by other noises,[5] such as coughing, a dog barking, a cabinet or door being closed, laughter, yelling, banging, knocking on a door or a wall, other sharp sounds, or noises from televisions and speakers. PatentThe Clapper was invented by Carlile R. Stevens and Dale E. Reamer, and issued U.S. Patent #5493618, which was published on 20 February 1996.[6] References1. ^{{cite news | url=https://news.google.com/newspapers?id=twIzAAAAIBAJ&sjid=UggGAAAAIBAJ&pg=6224%2C2334666 | title=A tale of useless toys | date=January 10, 2003 | work=The Free Lance-Star | accessdate=24 December 2013}} 2. ^{{cite book|last=Harry|first=Lou|title=As Seen on TV: 50 Amazing Products and the Commercials that Made Them Famous|year=2002|publisher=Chronicle Books|location=California|isbn=978-1-931686-09-9|pages=90–91|url=https://books.google.com/books?id=Q8_sMBcCVqEC&lpg=PT93&dq=%22the%20clapper%22%20clap%20on&pg=PT93#v=onepage&q&f=false|author2=Stall, Sam |chapter=The Clapper}} 3. ^{{cite news | url=http://www.kcbd.com/Global/story.asp?S=1059890 | title=The Clapper: Does It Work? | work=KCBD News | date=December 25, 2002 | accessdate=24 December 2013}}{{dead link|date=March 2019}} 4. ^{{cite web | url=https://gizmodo.com/5624015/the-21st-century-clapper | title=The 21st Century Clapper | website=Gizmodo | date=August 30, 2010 | accessdate=24 December 2013 | author=Lam, Brian}} 5. ^{{cite news | url=http://www.ktre.com/story/16366556/the-clapper-does-it-work | title=The Clapper: "Does It Work?" | work=KTRE News | accessdate=24 December 2013}} 6. ^{{cite web|title=Method and apparatus for activating switches in response to different acoustic signals|url=https://www.google.com/patents/US5493618|accessdate=2 November 2017}} Further reading
