Adding an audio input jack to a megaphone allows you to play music, sound effects, or use an external mic with your megaphone. This is a great mod for most cheaper model megaphones that do not come with an audio input jack. This was a quick and easy hack to perform and did not require permanently disabling any of the megaphone's functionality, such as the microphone. Follows are directions to help you perform this mod yourself.
Step 1: Go Get Stuff
You will need:
- A megaphone
- A 1/8" audio jack w/built in cutoff switch
