Specifically, the surface acoustic transducer comprises a primary assembly comprising a voice coil assembly having a voice coil former and wire, and a transducer housing for retaining said primary assembly and a magnet therein such in movable relations. The present surface acoustic transducer may further include a spider structured to provide an improved excursion. An external housing may additionally be provided comprising a rigid retaining wall for protecting the surface acoustic transducer from potential externally applied forces and a malleable excursion cover allowing for an excursion of the primary assembly thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surface acoustic transducer","description":"The present invention provides for a surface acoustic transducer optimally structured to produce sound within an aircraft cabin by vibrating the interior cabin walls.
