## Description

Listen up! This tiny 1" diameter speaker cone is the perfect addition to any small audio project where you need an 8 O impedance and will be using 0.5W or less of power. Adafruit particularly like this cone as it's very simple and its metal body is extremely lightweight. [It's very similar to the speaker in the Drawdio kit.](https://core-electronics.com.au/drawdio-kit-v1-1.html)
 
 Works great with Adafruit's [Wave shield](https://core-electronics.com.au/adafruit-wave-shield-for-arduino-kit-v1-1.html) or [class D amplifier board](https://core-electronics.com.au/stereo-3-7w-class-d-audio-amplifier-max98306.html). Just be careful not to overdrive it if you're using the class D amp breakouts as it can put 1.7W into the speaker, blowing it out! Start with lower volume and increase carefully.
