Staigen Posted March 16, 2006 Report Share Posted March 16, 2006 Hi kuwaiti badr, welcome to this forum, nice to have you here ;DCant you read, it is a piezo speaker, used as a sensor here. The speaker comesfrom a piezo buzzer. I belive you can use the piezo ringer from a modern telephoneas well, or an another piezo speaker.//Staigen Quote Link to comment Share on other sites More sharing options...
