You can use these speakers to create simple music or user interfaces.\u003c\/p\u003e\n\u003cp\u003eThis 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).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"http:\/\/cdn.sparkfun.com\/datasheets\/Components\/General\/cem-1203-42-.pdf\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":27864697415,"sku":"COM-07950","price":2.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/07950-1.jpg?v=1471512086","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/mini-speaker-pc-mount-12mm-2-048khz","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
