On the lower end of the device as seen on the diagram you see the following:

1. Speaker - the perforated one
2. Hardware screen lock
3. Audio jack

On the upper end;

1. Speaker
2. May be micro usb
3. I am not sure what the third one is

Then on the left side of the device:

1. power button in the center
2. zoom keys on the top
3. Power hole

Now compare with the image i posted in the thread. The lower end matches exactly.
