Click Window -> Open Perspective -> DDMS

If this directory already has a directory called ringtones , go to it or create a new directory with the name mnt/sdcard/ringtones .
Note. To create a new directory, you need to click the "+" (plus) icon in the upper right corner
To download ringtones, click Push a file on to device , again in the upper right corner and download ringtones. After that, you need to restart Eclipse, as well as the emulator.
