Question

When you listen to music using a speaker, the signal for the music must somehow travel from your phone to your speaker. How is this information communicated? How would the signal differ if you listened to soft versus loud music? How would the signal differ if you listened to a high-pitched violin versus a deep bass?

Once the music signal reaches your speakers, it must somehow be converted into sound. Discuss how the signal from question 2 is converted into sound waves. This question has multiple parts, and you should touch upon the following points.

PLEASE ONLY ANSWER c):

c) When you made your speakers, you had to use a coil of wire. How is a force produced when a current travels through the coil of wire? Demonstrate your knowledge of the right-hand rule and the Lorentz’ force law to explain what forces are acting on the coil. (10 points) Demonstrate your knowledge of Amperes law, the right-hand rule, and the Force law for magnetic charges to explain what forces are acting on the coil. (10points)
