When designing acoustic products, the speaker driver itself needs to go through quality assurance testing then again once the driver is implemented into the final product. The dual testing ensures the product works properly on its own and the surrounding device the speaker is introduced into is not causing the speaker to become defective. Amongst the many tests quality assurance puts a product through, in an acoustic product like a loudspeaker, detecting Rub & Buzz is critical before the product is shipped to the end customer. In this application note, we introduce what Rub & Buzz is and define four Rub & Buzz detection results used on production lines.
