How does a speaker work?

In this clip I demonstrate how a speaker works, in this case a guitar speaker. I go through how the ingoing parts such as the magnet, voice coil, voice coil former, back plate, front plate, pole piece, cone, gasket, suspension, spider and dust cap are related.

Thanks, Johan, for answering a simple question in under 5 minutes, using clear diagrams, just the right amount of science, and a concise, well-recorded narrative.

awesome lesson . internet bringss passionate teachers closer to eager students

[@josephdonahue2996]

I am a physics major and think I understand the Lorentz force equation... the magnetic field inside a ring magnet should resemble the force inside a solenoid, which is all in one direction with the same direction as the axis of the magnet. The voice coil is within this uniform field, with lets say the field pointing up at every point on the voice coil. If I pick a point on the voice coil and do the "right hand rule" for a cross product of current with the magnetic field, I get an "outward" force on the coil at each point, as if the coil is being forced to expand. This doesn't produce a force upwards or downwards on the coil. If I want the right hand rule to produce an upward force, I need the magnetic field(or some component of it) to be pointing "inwards" at every point on the coil. This is best produced at the ends of the magnetic gap or even outside the magnet... so is the ideal rest position placing the coils near the top or outside of the magnetic gap?

Hi, Johan! I can't get enough of your channel. Brilliant. I was wondering if you could explain sometime WHY different speakers sound different from each other from an design/engineering perspective? For example, Creambacks and Greenbacks LOOK like they're constructed similarly: Basket, paper cone, voice coil, ceramic magnet... But what is it that makes them emphasize different frequencies to sound different? For example, if I got a brand new Greenback and immediately re-coned it with a non-Celestion replacement cone, would it still sound like a Greenback? Why does an Alnico magnet make the speaker sound different from a ceramic magnet or an electro dynamic magnet? There are a lot of guys on KZbin who do speaker A/B comparisons, but you're an engineer and understand (and can explain) the actual mechanics better.

[@sarinapaparone]

A brilliant tutorial for a scientific dummy like me. Great stuff...I actually understand it thus far!

[@JohanSegeborn]

Thanks Freo, Glad to hear that! Cheers Johan

[@karimaddas7617]

thanks for the lovely video. the reason there is a force on the coil is not due to faradays law. if a wire with a current exists in a magnetic field, it experiences a force due to the magnetic part of the Lorentz force law

The pole pieces convert the ring magnet with a pole on opposite sides into a bent horse shoe magnet with the poles facing each other in the gap. Well imagine a ring of horse shoe magnets with the poles bent inwards to create a narrow ring shaped corridor with the north pole on one wall and the south pole on the other. In this sits the coil of wire, held in place perpendicular to the magnetic fields, such that the ring magnetic fields induced in each wire produce the strongest force upwards or downwards.

very interesting sir. you know i am fan of physics. there was an old speaker at my house. i knew that every speaker had a magnet. so i was eager to crack that and take out the magnet to play. but after i did it, i really didn't like to destroy it. i am planning to remake it in my own way and understand the mechanism so i will present in the science exhibition. help m with your appreciative videos.

THANKYOU so much Johan! You are an amazing Teacher Wish I could talk to you face to face. Ive always been perplexed about speakers. I do have a question: In a movie scene we may have a bird chirping and a person talking at the SAME TIME. How does the diaphragm produce these two pitch's simultaneously if it can only move at one frequency. Either it moves at pitch of bird or the person. Do you understand my question? I havent got a straight answer from anyone at university!

[@ron030363]

With bass at high volume, the excursion of the diaphragm or cone would cause the voice coil former to hit the inside back up the magnet structure. They make us believe the illusion of this cannot happen and this creates anxiety for the spirit due to fear of damage

Great voice

[@miscellanywell]

[@littlechildrenasmr5405]

This looks like AC work , what if DC made this...Can you explain to us the difference between AC current that Powers the amp and the difference between the speaker wires and the current that travels through them how it's different than electricity I don't understand.seems like the speakers pretty primitive for not changing how long of a long we've had it and it's amazing the work the wire work that goes into building it how intricate it is the wired out of this spooled is amazing

[@alexlee6129]

Thanks for the great video! I just have one quick question. What is the difference between the mechanism introduced 0:10 and the one you talked about later on. I made a simple speaker with the first method, and it worked just fine, does the latter produce a different sound?

[@JohanSegeborn]

+Alex Lee Thanks Alex! I think they are the same. The first concept where the magnet is moved through the coil and a signal or current is induced is basically a microphone. In a speaker you instead have a signal/current that you wanna transform into movement. Cheers Johan

[@TimpBizkit]

You get a stronger concentration of field lines at right angles to the coil with the second model, so it is more efficient. Field lines at right angle to the current flow gives the most force.

[@SamVieiraGuitar]

Thanks a lot for the video!! Im using a tube amp, and im sure you are aware that I cannot disconnect a speaker out of the amp while it is on because it will damage the output transformer. So I was thinking, can I remove the coil out of a speaker and wire it to a jack and use it as a dummy load for the amp? This was I can use the DI out without having to use the speaker, so is it possible?

[@benmacpherson2675]

grouse video johan have learned so much from you already just wondering i have a fender bassman and it has greenbacks in it. i would love to know exactly what that means. what makes it a greenback shorly its not just a colour thing. just trying to understand my amp better. cheers johan your the best. there jensen if that means anything

[@JohanSegeborn]

+Ben Macpherson Thanks Ben! Greenbacks are the Ceramic Celestion G12, G10 and G15 speakers made basically between 1965 and 1973. They all have speaker cones made by Pulsonic, Celestion changed to other cones RIC1 in 74 and those are often referred to as Creamback. During the Pulsonic period, green magnet covers were he most common, thereby the name. Jensen is an American speaker brand (today made in Italy) Cheers
