To translate voltage into sound, speakers use tweeters, woofers, and midrange cones as the drivers. You will find the physics behind speaker’s functionality complex, even though they consist of only a few parts in essence. Each component associated with the speaker must adhere to very precise specifications in order to work properly. The speaker’s performance depends upon every single one of these components. The Speaker baffle plays an important role in this; let’s take a look.
Function of Speaker Baffle
The speaker’s baffle functions as a mounting surface for the woofer, tweeter, and subwoofer while forming the front face of the speaker. You can prevent sound from the back and the front of the drivers from causing noise interference and colliding with the help of the baffle. Also, you’ll be able to easily hold the drivers in place with it. The speaker baffle creates better sound and blocks interference by ‘baffling’ frequencies, thus the name.
Speaker Baffle and Interference
You can create sound through waves of energy that you can express as sine waves by using the speaker baffle to vibrate the air at a specific frequency. The opposite of the desired sound wave will reach your ear as sound waves reflect and their timing changes. You will feel as if no sound occurred if the original sound wave and its opposite add up to zero after meeting at the same time.
Only the desired sound will reach your ears as a speaker baffle absorbs sound energy broadcast from the driver and prevents reflection. With the help of the baffle, the system is able to absorb some of the energy of sound waves that strike it while reflecting the rest.
You’ll find that it produces an effect similar to ripples of water fading out in a pool—until the pool is calm; the ripples continue to lose energy as they strike the sides of the pool.
Speaker manufacturers use the same material as the speaker enclosure for the baffle, even though they can fabricate baffles from any material. What will work just as well include wood, plastic, or metal material that will not vibrate when exposed to sound. Compared to other walls of the enclosure, you can make the baffles thinner. In order to ensure that they absorb and reflect enough energy, test your baffles if you plan on making your own.
Not all speaker drivers require baffles as the physics of sound states so. You cannot generate enough power for sound cancellation to be an issue with small or low-powered drivers found in standard headphones. Also, their own noise-cancellation function is something the low-powered drivers will often incorporate.
When multiple drivers generate a range of frequencies in a larger cabinet, baffles take center stage. You can also avoid environmental damage in installations of car stereos with the help of baffles. Speaker baffles are equally important as another other component associated with car speakers. Therefore, you should definitely consider getting speaker baffles for your car audio system.
