Micro Audio Amp
Audio signals from audio sources such as computers, laptops, and smartphones are strong enough to directly power headphones but not larger speakers. If large speakers need to be driven then an audio amplifier is required which amplifies the small signal so that large speakers can be properly driven. In this kit, you will build a Micro Audio Amp which can drive headphones and small speakers from common sources!

Applications
This kit is perfect for the classroom as it teaches about amplifiers, push-pull stages, and audio signals as well as providing a project that can be constructed in under an hour. However, the kit needs to be used in conjunction with an audio source that has wired outputs. This kit can be connected to 3.5mm audio jacks if a 3.5mm audio connector is connected to the kits input. The speaker supplied with the kit works best when used with an amplifying cone which can either be a paper cup, bowl, or old metal tin.
