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