商品說明

這是一款小巧的12mm圓形揚聲器,可在2kHz的可聽範圍內工作。您可以使用這些揚聲器創建簡單的音樂或用戶界面。

這不是真正的壓電揚聲器,但表現相似。這款微型揚聲器採用電磁鐵驅動薄金屬片,而不是用電流振動的壓電晶體。這意味著你需要使用某種形式的交流電來獲得聲音。好消息是這個揚聲器被調整為最好用方波(例如來自微控制器)。

=========================================================

 

This is a small 12mm round speaker that operates around the audible 2kHz range. 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).
