Abstract
An apparatus includes a voice coil bobbin for an electroacoustic driver. The bobbin has a plurality of cutouts for venting an interior of the bobbin. The bobbin includes a plurality of integral flanges at the end of the bobbin which can be used to secure a diaphragm to the end of the bobbin. Each of the flanges extends from the bobbin at an angle that is no more than about thirty nine degrees relative to a plane that is substantially perpendicular to an intended direction of travel of the bobbin during operation of the driver. An electrically conductive voice coil is wound around the bobbin.
