do speaker give off electro magnetic pulses?

Question

my printer wouldn't turn on again when i turned one of these on
(aside from making sparks from the camera flash circuit by charging it and placing a wire in betwing the capacitors terminals)

just wondering and pardon the spelling

it also started working again when i did two things
(someone said that the camera flash was producing emp so i thought there was inductance in the printer so i un pligged it from the wall got a wire and attached it to the terminals that go into the wall and held down the power button and it worked)

and it also started to work again when i reached for one of those flashlight that don't need batteries you just have to shake them to make them work and ran it across the printer's dc to ac adapter i think it atracted all the inductance like a magnet, it will reciave some inductance from the emp's given off from the sparks i was producing

Answer 1

A speaker works by applying an electromagnet to a speaker cone to produce movement and compression waves. So there is electrical current involved, but you're not going to have much ambient effect from normal electrical current.

It's more likely you just blew a fuse or had a power surge from turning something on.

Answer 2

Your question is somewhat confusing - and confusing a simple mind like mine isn't difficult.

Your main question - the answer is yes, but that isn't what makes the sound you hear - that's the cone compressing and expanding the air.

As far as the flash circuit, I sincerely hope you fully realize what these voltages are when you start "placing a wire between the capacitor terminals."

And your printer? Not a clue.

Answer 3

yes
