How does a microphone work? With materials listed
>>16777153>posts a solenoid>doesn't notice
you could always buy an introduction to radio or kids' radio guide book op
>>16777153it just does.
>>16777153An amplifier powered solenoid, fixed to a mechanical diaphram to move the air around.>I said microphone, not speaker.Oh whoopsA mechanical diaphram moved around by the air, fixed to a solenoid powering a sensing circuit.
>>16777267Friendship ended with paper plate speaker science project.New best friend is paper plate microphone science project.
>>16777153There's a couple of different ways microphones work. The one you pictured uses induction to convert vibrations in the air into an electrical signal by physically moving a coil through a stationary magnetic field. It's the same way that spinning a motor can generate current.One of the older ways we used to make microphones is called a carbon microphone. It is essentially two plates, one very thin, with carbon granules in between them. You run an electrical current through from one plate to the other, and the pressure from the air compresses and decompresses the plate, increasing and decreasing the resistance in proportion to the input.
>>16777153the vibrations in the micronoid generate different amounts of voltages which travels in the cable as sound waveshow does the sound come back out of diodes and capacitors? is it strored in the capacitors as sound?
>>16777511the cups and the string are just like the microphonnoid and the cables and the speakernoidmaybe can i make my string amplify the sound out of my paper cup on the other end of my string
>>16777153It's a transducer that converts mechanical energy into electrical energy. A fuggin speaker is a transducer that converts electrical energy into mechanical energy. Get with the program! You'll never be an audio engineer at this rate!
>>16777853Hey, let's add some tension to that string. Not much, but just enough, like a guitar or violin. Now we'll use my brother's new phone to take some slo-mo video of the vibrations.We should digitize the shit out this.
>>16777883does making the cables tighter increase the volume of my microphone or speker
>>16777897Idk, but it makes the video better.We should do some experiments.But do we publish or patent?
>>16777933maybe we could try using a comstrate with some resistance like elastic string to increase the vomume of my paper cup microphone
>>16777940maybe the stored energy in my comstrate will provelop into louder sound
>>16777897If your tightness is my capacitance, then yeah.
>>16777961have you tried using elacticated cables
>>16777963>more boingy, more doingygenius.
