Connecting iPod Shuffle to Speaker Dock

I have solved my problem of connecting my iPod Shuffle to my speaker dock and I wish to share my findings:

The issue is to get the signal out of my iPod Shuffle by using the earphone jack female connector so the connection cable has to have a 3.5mm male audio connector on one end. The dock has a 30-pin male connector into which fits the non-Shuffle iPods, and iPhone, 30-pin female connector. Thus, the other end of the cable must have a 30-pin female dock connector.

I found 2 cables with a 3.5mm male audio connector on one end and a 30-pin female dock connectoron the other end:
