Patent EP-0296139-A3 (EP)
IPC: H04R9/04
Filed: 1988-06-17
Abstract: An audio transducer device capable of acting as a full range 
speaker which achieves the propogation of a peaked wavefront from 
the diaphragm instead of generating a substantially planar 
wavefront as in the case of the common speaker construction 
utilizing a diaphragm driven as a piston. The speaker has a 
frame with a central open area in which is supported a substan­
tially planar, thin, flexible film forming the diaphragm. The 
diaphragm is driven by a driver which imparts motion to the 
diaphragm at a small source area preferrably centrally disposed 
of the diaphragm, the motion being imparted in a direction 
normal to the plane of the diaphragm so that ripples radiate 
from the drive area and travel at the same time across the 
flexible diaphragm, one behind the other, towards the frame. 
The drive area is small relative to the overall diaphragm and 
may be a point source or a line source. The rest of the 
diaphragm is driven by the central moving portion, endowing it 
with a built-in time delay, much in the same manner ripples move 
out in a still pond when a pebble is thrown into it. Because of 
the time delay involved in spreading the energy across the 
diaphragm, the wavefront radiated by the speaker gets a head 
start at the centre and lags towards the edges. The result is 
that of a spreading spherical wave front for a point source and 
a cylindrical wave front from a line source, and allowing a large 
diaphragm to behave as a small virtual audio source. This 
ensures excellent treble dispersion from a diaphragm capable of 
substantial bass response. In each case, the full range 
transducer requires no crossover, equalization or time delay 
circuits. The linear coil in the line source arrangement 
presents an amplifier with the ideal purely resistive load, with 
no substantial inductance or reactance. Similarly, the point 
source can be readily designed to present a simple load with only 
a mild inductive characteristic.
