The transducer section includes first and second cone loudspeakers arranged coaxially and in an opposed relationship. A compression plug having two input surfaces is mounted between diaphragms of the cone loudspeakers. Channels from the first and second cone loudspeakers feed common sound chambers located in a belt around the circular perimeter where they connect to external ports. A radial; folded waveguide has a circular throat which connects to the external ports."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radial waveguide for double cone transducers","description":"A radial waveguide assembly comprises a transducer section and a waveguide section.
