Question

How does putting my phone in a cup amplify the sound?

Carole Brock

Community Answer

Putting your phone in a cup compresses the waves of sound a little. This makes them louder.

Question

Does it sounds like real speakers?

Community Answer

It won't be as loud or clear as real speakers, but it will amplify the sound more than playing the music directly out of your phone.

Question

How long would this take to make?

Community Answer

if you are not decorating, then this will take about 3-4 minutes. If you are decorating, it will take about 5- 10 minutes. If you're painting, add 5 minutes of drying time.

Question

Will this work with plastic cups?

Community Answer

Yep! You can use any type of disposable cup you want. I think a Styrofoam cup might work as well.

Question

Why does it produce louder sound if we use these paper speakers?

Carole Brock

Community Answer

Sound is a wave, and when you compress it, rather than let it get weaker, it is louder.

Question

How do these paper cups and toilet paper roll make a much louder sound?

Community Answer

It amplifies the phone speakers to create more sound waves and more sound waves mean more volume! The sound quality is not great but phone speakers never sound good so at least you get more volume.
