Introducing Microphones and Speakers - The Learning Circuit

[@BarefootBushcraft]

Always helpful Karen. This series is one of the best on KZbin for beginners. I've recently shown my 9 year old niece the learning circuit, now she is smarter than I am! Haha thanks for all the great videos :)

Great video! Little detail: The string of your ukulele doesn't move air particle that much. The sound is mainly caused by the soundboard of the instrument and this phenomona depends on the rigidity of the bridge. But it is a current believe that the string can cause sound, in fact it will splits the air more than creating a soundwave :)

phantom power? The low amp voltage put on a microphone line to power up mics that require electricity. Usually it is +48 Volts DC. Most professional audio equipment can provide this power, when switched on.

I'm loving these answers to "What is phantom power?".

[@JoshuaPritt]

I remember using the Left ear of my cheap walkman headphones in 1996 as a microphone on my old PC to record my voice and send over AOL email. Just plug the headphones into the MIC input of the PC and talk into the Left ear and it worked great. All because speakers and microphones are basically the same thing!

Phantom power is the ability to power devices using the same wire for power and signals. Examples: pots telephones, professional microphones that has active circuitry, and power over Ethernet

[@luisdaniel3363]

Power over Ethernet isn't phantom, it uses separate wires for power.

[@harryrickenbach5890]

gigabit Ethernet uses all 4 pairs of wires for data. Power over Ethernet 802.3 AF and 802.3at uses 2 pairs for data and power and the other 2 pairs just have data 10\100 Ethernet only uses 2 pair for data and the other 2 pair for power

Still don't understand! How does the speaker identify the song it plays?

[@clemensmayer9171]

stunnign animations! and well explained!

[@MrCardeso]

Thanks, Karen!

[@nickstamatiou9871]

Excellent video

[@madcockney]

Phantom power was so called as it was induced from other circuits, and so called free power, from the likes of mixing desks, etc. If could also be safer than directly connected power. Being able to provide 48 volts made it ideal for microphones. However these days many supplies listed as "Phantom Power" are actually specially created from input power to 48 Volt power out so in reality the free "phantom" element disappeared.

This is so amazing! Thank you

[@Bob-tu9jq]

Fantastic!

Hi Karen. It would be great if element14 could make a playlist with your videos to make it easier to navigate.

[@maker_karen1785]

Jamie Lane There is already a playlist called The Learning Circuit. Are you having trouble finding it?

[@JD-ud6lq]

@@maker_karen1785 ah thanks Karen I found it on the home page. I was looking in the Playlists tab where it hasn't been added. Maybe it could be added here as well.

Liked commented and subscribed. Helpful tutorials.

Phantom power is a kind of power than cant be seen but some people believe exists. Some say its 48v for condenser mics.

[@thingnumbertwo2]

Neat and informative video!

[@jeffdlr3056]

Phantom power is from a Nickelodeon show by the name of Danny Phantom in which a teenage boy uses Phantom power to fight crime.

[@DAVIDGREGORYKERR]

What do the amplification using DSP processing and using a DAC at 16 times frequency and processed using a TI Blackfin DSP processor and using a R2R network and lopass filter to clean up the output and using high school math to do the donkey work. Just a thought

[@3DSage]

I 3D printed a speaker on my channel!

[@JoelHudson]

Oohhh Acoustic Transducers FTW

[@StigDesign]

Awesome :D Great explaned :) next how to make a microphone that is better tha the ons that are in HeadSet`s hehe ;D or a mic for pc/MobilePhone :)

[@adventureoflinkmk2]

Isn't phantom power kinda like a parasitic draw.. I mean from outta nowhere you find your car battery dead, until you get a new one and put an ammeter across the negative cable and battery terminal

[@sorow9523]

:) good video
