The invention provides a continuous layer of polymer that is shaped to act
as the suspension, the former, and an attachment to the diaphragm. The
coil may be located within the pocket providing insulation to the coil
thus preventing electrical short circuiting of the voice coil as the
voice coil expands or contracts based on its operating temperature. The
invention also provides an inner flange area of a suspension that may act
as a spring generating additional acoustic energy from the compression
driver. The inner flange area may also be tuned to vibrate at a
predetermined high frequency. Thus, in certain applications, where more
acoustic energy is desired at high frequency, the inner flange area may
be tuned to provide that extra acoustic energy. To further increase the
high frequency energy generated by the compression driver, the diaphragm
may be coupled to the bottom side of the inner flange area. Such an
arrangement places the diaphragm closer to the phasing plug to minimize
the space or cavity between the two. With a smaller cavity, the resonance
in the cavity increases, so that the compression driver generates more
energy at high frequency.
