A speaker enclosure using a passive radiator (PR) usually contains an "active loudspeaker" (or main driver), and a passive radiator (also known as a "drone cone"). The active loudspeaker is a normal driver, and the passive radiator is of similar construction, but without a voice coil and magnet assembly. It is not attached to a voice coil or wired to an electrical circuit or power amplifier. The passive-radiator principle was identified as being particularly useful in compact systems where vent realization is difficult or impossible, but it can also be applied satisfactorily to larger systems.
Passive radiators are used in many modern speakers because they are a terrific way to get a whole lot of extra oomph out of a sound system without diverting valuable energy into creating that lovely bass effect that we all enjoy so much.
A passive radiator is powered by the air pressure generated by the smaller powered speaker inside a modern sound system. They use a subtle and clever method to do a lot of work using very little power. It cancels out vibration and noise significantly, bringing in high fidelity sound quality.
Cone body: Material cutting → Cone body Forming → Cone body Cutting → Surface anodized or painting
Rubber surround: Raw material preparation → Material Mixing → Milling → Cutting → Vulcanization → Gluing → Baking through the oven
Cone Assembly: Assembly → Reinforcement → Packing → Outgoing inspection
Passive radiators are used in Bluetooth speakers, home stereo speakers, subwoofer cabinets and car audio speaker systems, particularly in cases where there is not enough space for a port or vent system. While most studio monitor speakers are either ported bass reflex design, or closed-back without a vent or passive radiator, Mackie's HR824 and HR624 monitor speakers have a passive radiator installed on the rear of the cabinet. Focal also sells a studio monitor with a passive radiator called the SM9.
Respective examples of a smart speaker and a portable Bluetooth Speaker utilizing passive radiators are Apple's HomePod mini and Ultimate Ears' UE Boom.
