How does the DS know when it's been closed?

    Just playing around with my DS and got to thinking about this.

    When you close the DS, the screens turn off and it goes into standby mode or whatever, to save battery, blah, blah.

    But how does the Ds know that its been closed?

    There's no obvious switches anywhere near the hinge, but once you close it far enough, the screens turn off. How?

    Very mysterious! or am I missing something simple?

    actually there is a magnet in each of the speakers.there is a sensor between the a,b,x, and y buttons (probably hall effect) which activates sleep mode when brought near a magnetic field.
