You can use these speakers to create simple music or user interfaces.This is not a true piezoelectric speaker but behaves similarly. Instead of a piezoelectric crystal that vibrates with an electric current, this tiny speaker uses an electromagnet to drive a thin metal sheet. That means you need to use some form of alternating current to get sound. The good news is that this speaker is tuned to respond best with a square wave (e.g. from a microcontroller).Documents:Datasheet","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":10789,"title":"Default Title","sku":"SF-COM-07950","price":4.92,"on_sale":false,"in_stock":true,"available_quantity":1966,"option1":"Default Title"}]}
