Hi, my task is to build an audio amplifier for an mp3 player 3.5mm output, the spec says to run it on 3 AA batteries (4.5V), and to have a pre-amp, tone control and output amp.
Now i have the circuit all wired up and working, however we are given these cheap miniature loudspeakers to use (mylar) and the problem is they are terrible at handling bass, it just sounds like noise really, however if i remove the bass with my bass control circuit i get a nice output. I'm sure if my research is right they are only designed to handle frequencies above 400hz which is obviously the problem.
Now we are allowed to purchase other components if they are cheap and readily available, but i would like some advice on purchasing some speakers that can handle the full audio range (i think it was 20hz-20khz), which are small in size and power rating, and are cheap and readily available. We are currently using speakers i believe are rated at 8Ω with a power of 1W max.
As you can tell i don't really have any experience when it comes to loudspeakers and audio, so i don't know what info you might need or how stupid this question may be.
Thanks,
James
