#Raid Your Kitchen To Build This Potato chip Speakerin 1921 two scientists made the first modern loudspeaker out of magnets wire and paper. Now manufacturers use synthetic fibers and even ferrofluid. Why stop there? Your kitchen contains plenty of materials to build a functional woofer. A potato chip works as a sound-emitting diaphragm here but other rigid foods work just as well. Time: 5 to 10 minutescost: A few bucksdifficulty: 1/51) Gather the parts 25 feet of 30-gauge magnet wire Two-inch-diameter-by--inch cylindrical refrigerator magnets Two cardboard strips inch by 1. 5 inches A wooden cutting board or piece of particleboard One 6-inch-long-inch-diameter dowel Sandpaper A hot-glue gun Potato chips (thick-cut chips work best) 2) Build a voice coil Wrap the magnet wire tightly around the dowel to make a Ã¢Âinch-tall coil leaving 12 inches of wire on each end. Smear the coil with hot glue let it cool and slide the coil off the dowel. Sand an inch of paint off the wire's ends. 3) Assemble the speaker Fold the cardboard strips into A z shape. Hot-glue the magnets and strips to the particleboard and then the coil to a chip. Next glue a cardboard strip to each end of the chip while centering the coil over the magnet. 4) Rock out Connect the sanded speaker wires to an amplified audio source such as a home entertainment center (a portable player may lack enough power) and listen to the saltiest crispiest music you've ever played. Here is a song to play out of your potato chip speaker!..One potato two potato three potato four Five potato six potato seven potato more Potato chip yeah Potato chips now alright She always flips when she gets her grip on a crunchy munchy potato chipi got a girl she makes me flip All she wants is potato chips Whoa potato chips yeah What I say She always flips when she gets her grip on a crunchy munchy potato chipshe don't like'em hashed she don't like'em fried But there's only one way to make her satisfied Potato chip whoa Potato chips now you gotta listen to me She always flips when she gets her grip on a crunchy munchy potato chipwhoa yeah c'mon baby c'mon girl c'mon baby c'mon girl whoa whoa yeah She moves me and grooves me she's a mass of class a real gas My one and only potato chip She's my potato chip She's my potato chip She's my potato chip whoa She's my potato chipa potato chip works as a sound-emitting diaphragm here but other rigid foods work just as well. No they don't; the more flexible the better. If you want to make a fun loudspeaker (that works well) tape a coil to the side of an inflated balloon feed a signal in and bring near to a powerful permanent magnet-magic! My name is Sophia. I am 10 years old and my father just helped me make this for my science fair project. We not only made a a potato chip speaker but we also used a paper plate and a piece of swiss cheese and a tortilla chip. All of them worked. We thought the piece of cheese was a little too much so we tried one with just the coil and magnet and it worked also. So is the potato chip really doing anything? We could hear differences between the the different diaphragms but that might have been because we used different coils. Can anyone help us understand what is happening here? Why would the coil and magnet work without a diaphragm? Thanks for sharing this very informative article indeed you have provided us with a useful content that we can apply in our daily lives.
