Weatherproof 50mm ultra slim mylar cone speaker 8Ω 0.5W for portable equipment
Description:
Traditional speakers produce sound by using an electromagnet to move a flexible cone back and forth. They use drivers to help translate electrical signals into physical vibrations so that you can hear recorded sounds. A tweeter is the type of speaker driver that produces the highest range frequency. The other two main drivers are woofers and midrange.
Basically, a driver moves a flexible cone, or diaphragm, back and forth very quickly to produce sound waves. The diaphragm is normally made of paper, plastic or metal and it's attached to the suspension's wide end. The suspension, also called the surround, is a flexible metal rim that lets the cone move. It's connected to the basket, which is the driver's metal frame. On the narrow end of the cone is a voice coil, which hooks up to the basket via a flexible metal ring that lets the coil move back and forth while still keeping it in place.
