I research the internet for a long time and concluded that Basically it's a hardware problem. There is dust in your phone.

It's actually very easy to fix.

1) grab your phone and with  the top end of the phone hit  a soft surface like a sofa or pillow hard a few times and it will remove the dust from the speaker.

You can open it up and clean it but I wouldn't risk it.
