Step 5: Step 5: Test speaker (Battery test)

Using the 1.5-V battery with the loudspeaker, briefly connect the ends of the coil wires to the battery terminals. (One student lightly taps one battery connection on and off while her partner lightly touches the top of the lid or listens to the speaker close to her ear.) Students
feel and hear a light tapping as the battery connection is alternately made and broken. They might also be able to see the lid moving.
try replacing the decoupling capacitor in your radio, see if that makes your radio work<br>
Your loudspeaker is a complete fail, not because it was boring, but because it broke my radio!
So are the speakers loud and can you include like a video of it in action.
