Custom earbud scanning and fabrication

A method comprising:

• performing a first scan, with at least a first scanner, of an interior shape of a cavity, the first scan of the interior shape comprising:
• inflating an inflatable membrane with a medium, the inflating of the inflatable membrane conforms an exterior surface of the inflatable membrane to the interior shape of the cavity;
• generating light from an emitter to at least illuminate an interior surface of the inflatable membrane;
• detecting, at a detector, light from the interior surface of the inflatable membrane, the light comprising a first optical wavelength and a second optical wavelength;
• and
• generating, at a processor, a first electronic representation of the interior shape, the generating being based at least on the detected light;
• performing a second scan of a second shape proximate to the cavity, the second scan of the second shape generates a second electronic representation of the second shape;
• modifying, at a design computer, the first electronic representation into a three-dimensional shape corresponding to at least a portion of the interior shape;
• generating, at the design computer, a combined electronic representation comprising the first electronic representation and the second electronic representation;
• fabricating, at a fabricator, an earbud, the fabricating based at least on the combined electronic representation;
• and
• actuating, between an extended position and a retracted position, a scanning tip, the scanning tip comprising the emitter and the detector and the scanning tip being actuated during the generating and detecting of the light.

A method comprising:

• performing a first scan, with at least a first scanner, of an interior shape of a cavity, the first scan of the interior shape comprising detecting, at a detector, light comprising a first optical wavelength and a second optical wavelength, the detected light generated by at least one of:
• detecting structured light generated from a pattern imprinted on an interior surface of an inflatable membrane;
• and
• emitting, by an emitter, structured light to form a pattern on the interior surface of the inflatable membrane conforming to an interior shape of an ear and the detected light generated by reflection of the structured light from the interior surface;
• and
• generating, at a processor, a first electronic representation of the interior shape, the generating being based at least on the detected structured light;
