Why 8 ohms speaker are used in Mobile phones

Piyush Gaur New member Username: Piyush_gaur Post Number: 2 Registered: Sep-09	Posted on Thursday, September 03, 2009 - 06:41 GMT hi just want to know why 8 ohms speakers are use din Mobiles phones and not 4 ohms or 16 ohms speaker. i understand 4 ohms will draw more current and hence are not used. in that case why 16 ohms are not used as they will draw less current than 8 ohms. regards Piyush

It is 8 for now, but they are on rations. Whiz kids are working on just one really small one even as we speak. Her name is Milli.

Use less currrent and the battery lasts longer. I doubt heat has anything to do with a mobile phone's speaker choice since ic's don't produce much heat. .
