The diagram illustrates a basic mp3 player dock.
On either side of the dock are speakers which take up almost the full height of the unit, and take about one fifth of the width each. On the top is a protruding button to turn the unit off or on.
In the middle of the dock is a section where the mp3 player sits. At the base of this section is a series of pins that power the mp3 player and allow it to connect with the speakers. To the left of this is a red hexagonal receiver for remote control devices and to the right is a volume control knob.
Below this section is a digital clock, to the right of which are the clock control buttons which allow an alarm to be set. To the left of the entire unit is a power cable, and at the base of the unit are two oval shaped feet.
This ends this description of the mp3 dock.
