MR Series microphones combine a conventional element with a waterproof bellows assembly. The bellows conducts sound to the element and survives 15m (50 feet) of submersion in water. They may be panel mounted, attached for boom applications and are suitable for outdoor use or repeated submersion.
Knowles is the originator of balanced armature technology which they apply to their receiver, specialty transducers and hearing aid products. Knowles is also a market-leading manufacturer of MEMS microphones, electret microphones, voice processors and acoustical component accessories.
