Abstract
An inertial acoustic pickup (300) for use with a string musical instrument (700) having a soundboard (702) for delivering acoustic energy, comprises a chassis (302) including a coil (304) coupled to the soundboard (702), an armature including upper and lower substantially parallel planar suspension members (310) having planar perimeter regions (308) coupled to the chassis (302), and comprising a plurality of independent planar circular non-linear spring members (312) arranged regularly about a central planar region (314) within the planar perimeter region (305), an inertial mass (316) suspended between the upper and lower planar suspension members (310) about the central planar region (314) and having an axis (342) extending therebetween and including a plurality of permanent magnets (320) arranged regularly about a perimeter of the inertial mass (316), whereby acoustic energy coupled to the chassis (302) from the soundboard (702) is transformed through the planar non-linear spring members (312) into motional energy generated in a direction parallel to the axis (342) of the inertial mass (316) thereby generating an audio output signal in response to movement of the plurality of mag…
