Knowles RAB Balanced Armature Drivers for premium earphones and communications earpieces feature an efficient design that provides high output in a small size. Dimensions of only 5.15mm x 2.96mm x 2.58mm help the designer to develop smaller, more comfortable devices. Requiring less power per output SPL than typical dynamic speakers, Knowles RAB Balanced Armature drivers can extend operating time in battery powered devices, such as smart earphones, Bluetooth headsets, and surveillance earpieces. These drivers' low magnetic radiation eases incorporation into devices with other magnetically-sensitive components, such as telecoils typically built into covert earpieces using neck loops.
