Ok,pretty sure I know how the belt works.The lock seed gets placed in it from the top.The wearer pulls the knife handle,cutting the fruit on the lock in half and quickly pulling the knife back up.The cut half swings down and hangs there,revealing inside the fruit either the symbol of the rider or the current power.My guess is that the electronice are either in the lock itself or it reads like a switch or Beast Battery does,or both.

What I mean is that when you look at a normal padlock,the metal bar that locks into the lock itself has a notch.I'm thinking the bars on the different lock seeds have different notches,letting the belt itself identify the lock.When the fruit is cut,the front half falls away,triggering the sound effects by a tab holding the front half of the fruit in.So the electronics in the belt identify which fruit it is and the electronics in the lock identify the powers they use.
