ETron Circuit LabsLab 9Intro to SpeakersObjective:In this Lab you will learn how a Speaker works and build a simple circuit to observe that a Speaker turns electrical energy into sound.Step 1 – Take InventoryUsing the Parts Inventory as shown on the right under the “Here’s What You’ll Need” section, place each part needed for this experiment on its corresponding drawing. Observe the schematic symbol for each part. Make sure that you have all the parts ready before you begin Step 2.Step 2 – Build the CircuitUsing the Schematic Diagram and the picture of the completed lab, build the lab experiment with the electronic components. Use the “Check Your Work Here” Box to verify that your wiring is correct, and then proceed to Step 3.Step 3 – Do ExperimentTheory:In this simple electronic circuit, the electrons flow from the battery, through the resistor, through the Speaker, and back to the battery. A Speaker is an electromechanical device. It has a coil, a magnet, and a paper cone. These three parts are16
