Physics Assignment Possibly on Headphones?

[tengarp]

So, idk if this is in the right sub forum but i know that some of you guys have an understanding of headphones in an in depth way. Anyways, my Physics teacher assigned us a 12 page paper and we can do it on anything we want as long as he approves it. Thus, I thought about doing it on headphones (maybe orthodynamic cuz magnets i think). But ya, i just wanted to know if you guys who know about this topic see it as a good idea, and not ALL of the paper will we words, some are calculations and graphs and tables but i need to be able to write a lot about it. If you want any more details i can give it but yeah...

What are you required to prove in this assignment?  Do you need to provide basic knowledge and application of Newtonian physics? does it need to center around electrical or electromotive theory or both?  Headphones can be prime examples of most physics but you may need to go into amplifiers and acoustics to properly explain pending the assessment rubric.

we have to talk about the history of the technology and its modern applications. As far as the physics goes we have to talk about how it works and the equations that govern its operation, IF this is too similar to an amp i might not do it, because he recommends that we do not do a guitar amp as our topic...

also thanks for the help

I'd talk to him about it. You'd likely have to cover speakers in general and not just different types of headphones

ok, i will deff do it tomorrow thanks for the help

Okay, so I asked him today and he said that doing headphones or speakers would be a very good idea. He said that as far as headphones go, I can talk about the different types (ex: orthodynamic, dynamic, etc...) and how they are different but I should not focus too much about on that and still have how the electronics themselves and the physics of them work. He also said thought that I could either add something about speakers or do the actual report on speakers instead, as those comprise of sub woofers, woofers, tweeters, and the like, as with those I may be able to talk more about frequency response, cut off and more physics-related topics, as well as power and driving them. So now I am leaning more towards speakers as there are more types of drivers that can have graphs of such response. Anyways, tell me what you guys think i will be writing a paragraph soon on my topic and how the physics works.

PS: he also said that he does not like it when people leave out descriptions of the electronics themselves so keep that in mind if that makes a difference

Definitely do speakers then, the electronic side of the amp is not that difficult to explain, however it is sufficiently complex that if you need to pad out your paper you don't have to dig too deep.

 

Sub woofers all by them selves encompass, wavelength, rarefaction, air pressure, volume, displacement, resonance. To name a few, and that's before you even get into impedance, electromagnetic force, inductance Equivalence volumes etc etc etc.

okay lol ya that seems like alot of topics i can go over, it is 12 pages i guess. thanks for your response i think I'll definaetley go for speakers

hey guys, remember this physics assignment? Well we've finally started doing it and my work has been going very well so far. The only issue I have been running into is that I cannot find any sites that give specific equations for the physics behind the speakers. I realize teat there would have to be frequency and such for the size of the speaker, but what about the other various factors in speakers? This site talks about the frequency equations, but do you guys know anything about the other factors? This would include type of container, size of container, maybe type of materials although that might be too much. I was considering impedance as well but I'm not entirely sure if that's a good idea. Anyways, thanks for the help as always!
