ABSTRACT:
A driver unit for an audio speaker has a stationary component and a vibrating component associated with an automotive audio system and fixed to the vehicle panel. The stationary component is suspended from the vehicle body so that an electromagnetic section of the vibrating component is subject to a permanent magnetic field generated by the stationary component. A guide member is interposed between the stationary component and the vibrating component for guiding movement of the vibrating component in the axial direction. The guide member is adapted to restrict movement of the vibrating component in the direction perpendicular to the axial direction in order to prevent the vibrating component from being displaced laterally in relation to the permanent magnetic field.
