Solo cup phone speaker
Being the curious type, I naturally wanted to try this out myself. Guess what? It works, at least to amplify the sound. Does it sound any better? Well, no, not really, but it definitely sounds louder , and if louder is your intention then cutting a little hole into a paper towel roll and jamming your iPhone into it while blasting some music or a podcast will serve the purpose to amplify the audio with very little effort. Maybe adjusting some settings and the music EQ would make it sound better , but really if you want some decent iPhone speakers, just buy some or use an AUX cable to connect them to an existing setup.

String Telephone Explanation: How Sound Waves Travel
The old "two cans and a string" technique or better yet, "two paper cups and a string" really does work. The key is to make sure that the string is tight between the two cups, and this normally means that the distance is limited and the two people have to be connected to each other by a straight line. But as long as the string is tight, it works. It is also a great way to understand how telephones and radio work. To try this technique, take two large paper cups and punch a tiny hole in the center of the bottom of each with a sewing needle or similar.
Take a piece perhaps feet [30 meters] of non-stretchable thread or kite string and thread each end through each hole.
Either knot or tape the string so it cannot go back through the hole when the string is stretched. Now with two people, have each one take one of the cups and spread apart until the string is tight. If one of you talks into one of the cups while the other listens, the second person should be able to hear what the first person says. Here is why it works. Imagine the bottom of the cup moving back and forth very quickly 1, times per second or more with the sound waves of the speaker's voice.
The vibrations travel through the string by pulling the string back and forth. Therefore, the bottom of the second cup should start to vibrate back and forth just like the bottom of the first cup is vibrating, producing sound waves. The second person can hear the sound waves and can therefore hear what the first person says. This is not much different from how a telephone works , except that electric current replaces the string in a telephone. In an old-style telephone, the person speaking vibrates a metal diaphragm.
The diaphragm's vibrations rapidly compress and uncompressed carbon granules, changing their resistance. A current passing through the granules is strengthened or lessened by the changing resistance. At the other end, the rapidly changing current runs through a speaker and causes its diaphragm to vibrate back and forth, so the second person hears the first person speaking. See How Telephones Work for details. In a radio, the changing current from the microphone is used to modulate a radio transmitter.
The modulations are sent through the air to a radio receiver, which turns the modulations into the vibrations of a speaker, and the second person hears the first person speaking.
In a compact disc or a cassette tape , the sound waves vibrate the microphone and the vibrations are recorded on the tape or CD. In the tape, they are stored as magnetic fields in iron oxide. On a CD the vibrations are digitized and then written onto the face of the CD.

Physical Science. Can two cans and a string really be used to talk over a distance? Updated: Apr 28, Yes, it does, though it has distance limitations. A tin can and string phone works using a string instead of an electrical current to transport the sound vibrations.
What kind of string do you use for a tin can phone? A tin can phone typically uses a tight, non-stretchable thread or string to transmit sound. How do you make a tin can telephone? To make a tin can telephone, you need two paper cups, a piece of kite string or thread up to feet and tape. First, you need to punch a tiny hole in the center of the cup's bottom.
You use a pin or sewing needle for this. Next, you need to tie a knot or tape the string at both ends. Get two people to hold a cup, and make them go further apart until the string is no longer loose. Speak one at a time, and you should be able to hear one another if you press the cup around your ear.
How far can a tin can phone work? Depending on the quality of the string, a tin can phone can work up to feet. However, the further you go, the weaker the vibrations become and the quieter the sound will be. Cite This! Try Our Sudoku Puzzles! More Awesome Stuff.

This DIY boombox can save your next party
If you listen to music all the time, you might be familiar with the struggle of it never being loud enough. Speakers are expensive or sometimes you forget to bring it with you somewhere but what is a good party without loud music you can scream along with, without anyone actually hearing your voice? You can make your own speaker quickly and with objects you probably already own! These speakers are a major life hack, perfect to use when you just want a mini dance party in your room. All you have to do is play your music and put your phone in a cup! It will not be super loud but you will definitely hear a difference. For this one, all you need are clean, empty soda cans and the cardboard from a toilet paper roll. All you need to do is cut a hole in the sides of two soda cans, big enough for the toilet paper roll to fit in. Cut a hole in the middle of the roll to stick your phone in. Lastly, secure the toilet paper roll between the two cans.
Passive Smartphone Amplifier
Did you know you can make speakers out of almost anything? In this Instructable, we'll take the ever popular solo cup and show you how you can turn them into audio speakers! The first step to making your own speakers is to create a coil of wire, one for each speaker. These coils can be easy to make.

So instead we went low tech and created a DIY phone amplifier and stand from a toilet roll and a couple of paper cups. It is remarkable just how much of a difference this simple DIY phone amplifier and stand makes. It ensured that we could all hear the music. It was also a fab way to learn about sound waves, so yes we explored the science of sound too. It is turning a fairly omnidirectional speaker on the bottom of the phone into a directional antenna. Take your phone and trace around the bottom on the toilet roll.

Plug the mini phone plug into your radio, phone or other device, then turn it on and play some music you may have to turn the volume up louder than you normally would. With one hand, hold the cup to your ear.
Sound Design Stack Exchange is a question and answer site for sound engineers, producers, editors, and enthusiasts. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. We hypothesized that the sound was "amplified" because it directed the sound toward the front. We tested this by turning around the "speaker" and we found that indeed it was louder in front, but it was also louder in back than when the iphone is out of the speaker. We then hypothesized it had something to do with the sound vibrations in the cardboard, but when holding the iphone speaker to the cardboard directly without putting it into the "speaker", it didn't make any difference. Can someone explain why this appears to "amplify" the sound, and what effects we are experiencing with this?
