i urgently need a speaker simulator program for the project. i try searching my intrnet but cannot find much that is good. please someone must have some like anyone have library or source code for it?
"speaker is money and too big"
So just get a small, cheap speaker!
You have never stated anything about size or cost constraints in your previous posts - so how was anyone supposed to guess that??
Again, nobody knows anything at all about your project apart from what you explicitly describe in your posts! You cannot expect useful answers if you don't explain what the question is!!
"my watch is small and no speaker but it sounds because procesor make sound!"
Wrong: your watch does contain a miniature "speaker"
It probably actually uses a Piezo-electric transducer - commonly known as a "Piezo buzzer" or "Piezo sounder" or similar.
"you understand now?"
Gradually getting there - but you still haven't said what sounds you want to make...
i want it to sound music
i like sara kibuts on mp3
You cannot get good sound reproduction without good speakers - and good speakers are inherently large and expensive.
The size is governed by the laws of physics - there's nothing you can do about that.
Does the speaker have to be integral to your project?
Couldn't you just provide a socket for earphones - like most MP3 players...?
