Large Speaker Driver needed.? Answered
I have a large 8ohm speaker with a "12W500" rating, and another sticker saying 3/38/5 (QC check?)
~18cm Magnet and 30cm Cone.
I want a signal generator for chladni plate (vibrating plate)
I know how to make a signal generator from a 555, but i dont know how to drive the speaker magnet.
Do I put the output to a "power transistor"? I have only used them for signal amplification before not power supply..
Will it run on 12V, 3V 24V? What kind of amps may it draw 200mA 500mA? 1A? 4A? I don't even know ballpark figures!
Any tips, Circuits or transistor reccomendations will be VERY appreciated... I am fairly proficient at electronics, but this eludes me completely as it is taken for granted in most instances, or they use a 300€ amplifier....
I already build a signal generator.
