The Horn

Because the STONE serial port screen comes with an Audio driver and reserved the corresponding interface, so you can use the most common magnet loudspeaker, commonly known as horn. The loudspeaker is a kind of transducer that converts electrical signals into sound signals. The loudspeaker is one of the weakest components in sound equipment and one of the most important components for sound effects. There are many kinds of loudspeakers and the prices vary greatly. Audio electrical energy produces sound by making its paper basin or diaphragm vibrate and resonate (resonate) with the surrounding air through an electromagnetic, piezoelectric, or electrostatic effect.
