    Hi,
    Can I amplify a card toy music chip circuit?
    If so how can I do that?[​IMG]
    Can somebody suggest a simple way?
    Chip is something like in the attachment.

    Try some PC speakers, or any speakers with a headphone cable. Cut the male end off the headphone cable and touch the center wire to one of the solder points on the speaker.

    or addon a plug to plug the speakers in.

    If you really wanted to build a circuit you could use a simple op-amp.....I think.

    No.
    An opamp does not have enough output current to drive a speaker. You need a power amp, not an opamp.

    That is why using a powered computer speaker was mentioned. It already has a power amp in it.
