LOUDSPEAKER COMPOSITE COAXIAL DIFFUSER Russian patent published in 2018 - IPC H04R1/24 

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics, particularly to loudspeakers. Loudspeaker composite coaxial diffuser is configured to minimize distortions during the sound reproduction and is the main element of loudspeaker comprising housing, permanent magnet, diffuser suspension system, voice coil, characterized in that the diffuser consists of two independent parts: the diffuser active part, which is located in the speaker center cone or disk, powered by the audio frequency amplifier and the diffuser stabilizing part, which is configured to accumulate the central part sound energy, has the form of ring with two suspensions – upper and lower, the upper suspension is fixed to metal basket, the lower one is fixed to the mounting ring, which is located around the diffuser active part, the diffuser stabilizing part accumulates the central part sound energy radiated by it in the frontal plane, outside the active part and the energy reflected from the diffuser active part back side, transforming it into sound, the diffuser active and stabilizing parts are configured to operate in the one air volume and create sound together.
