Why is Phonon not connecting?

Question

Python

I'm trying to connect the Phonon sound output library in this way:

from PyQt4 import QtGui,QtCore
from PyQt4.phonon import Phonon

And what I get in the terminal:

Traceback (most recent call last):
  File "player.py", line 6, in <module>
    from PyQt4.phonon import Phonon
ImportError: No module named phonon

Although I installed packages with phonon before, but still such an error, how to fix it?
