speakers Answered

hey you guys are all so creative and knowledgable, this site is so great (tho terrible for my procrastination) does anyone know how to build a speaker to fit certain dimensions? like how flat could i make a speaker, and how loud would it be for something only a half inch thick (if thats possible) and up to 12" wide? it is meant to plug into an mp3 for power source etc.

i saw something on how they make speaker on tv what they do is put a permanent magnet in and also a electro-magnet in then they put the outer carboard on and then when power is supplied to the electro-magnet it repels against the permanent one andvibrates and since sound is actually vibrated air the cardboard moves the air better. (the temperary magnet is connected to the cardboard) and well i dont know what an amp does but i think it gives more power to the electro-magnet. so if you had it flat it would probly produce less sound because of the air flow. back to what andy said is yes you would need an amp. making it too flat would also have to make the magnets smaller and the smaller the magnets the smaller the speaker/sound.

If you tried to make a speaker no doubt you would be able to do it but unless you knew what you were doing it would be very quiet and probably quite poor quality sound. If by mp3 power source you mean the audio output I can guarantee that it will be very quiet. You probably want to look into the projects on this site (portable self powered speakers) and thinks like the minty boost. if you really want to make your own I would suggest (for pure flatness) attaching one or more piezo speakers to a rigid board (you would probably want some strong glue for this) of the dimensions you require and wiring them up together (in parallel) then to a powerful audio source, probably an amp (like I said, there are a number of projects on this site that do just that). Hope this helps, Andy
