In certain implementations, an earpiece includes an electro-acoustic transducer and an acoustic back volume configured to provide a desirable fit along with desirable acoustic performance. In some particular aspects, an earpiece includes: an electro-acoustic transducer; a housing supporting the electro-acoustic transducer such that the housing and the electro-acoustic transducer together define a first acoustic volume and a second acoustic volume, the electro-acoustic transducer being arranged such that a first radiating surface of the transducer radiates acoustic energy into the first acoustic volume coupled to an outlet and such that a second radiating surface of the transducer radiates acoustic energy into the second acoustic volume, where at least a portion of the second acoustic volume is located between the first radiating surface and the outlet."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Earpiece with moving coil transducer and acoustic back volume","description":"Various implementations include audio devices and related earpieces.
