    I want to remove the mic from my mobile or the hand free of my mobile and join the output terminals of the sound card of my computer or a music player to the mobile so that the music could be listened to the other person whom I m calling to.

    Do I need a circuit for this??
    How the sound quality will increase?

    The output level from a mic is extremely low and it needs to have a preamplifier.
    The output level from your sound card is at a much higher level.

    So you need to amplify the mic signal then make a mixer circuit to mix together the two signals.

    The sound quality will remain as bad as the sound from a telephone.

    Make friends with an electronics geek and he will make the circuit for you.
