Miniature Megaphone

Other Miscellaneous
1

Hi all, I’m new to electronics tinkering and am looking to make a miniature megaphone (that’s the best way to describe it). An important aspect is that it must be mobile - AKA can’t be connected constantly to a power supply. I was looking on sparkfun’s website for products to help me make this. I found the following but am unsure about a microphone to get it to work:

SparkFun Mono Audio Amp Breakout: https://www.sparkfun.com/products/11044

Speaker - 0.5W (8 Ohm): https://www.sparkfun.com/products/9151

Battery Supply: https://www.sparkfun.com/products/10891

Any recommendations for the setup and a microphone? Do these seem like good products for my project? Thanks for the help!

Looks like sparkfun has two microphones that might work for you.

    • Everything else looks like it would work for you.
