although you havent specifically said whats the problem with your speaker, I have searched the web for some possible ways to fix the speaker problem on your Lenovo A6000 phone. Here are some steps you can try to fix it:
* Check the speaker assembly for possible damage or misalignment. Use a multimeter to check it, replace if already busted. If the speaker is okay, check and clean the speaker terminal contact pads.
