AxiDriver is a BEM simulator. The program calculates the sound pressure in front and
to the rear of a loudspeaker-driver with a cone, dome or piston type rigid diaphragm
radiating from an infinite baffle. The baffle can be extended into waveguides of
arbitrary shape, as long as it is axis-symmetric. It is also possible to place
reflectors in front of the diaphragm.
AxiDriver provides valuable information about the radiation pattern
in the near- and far-field. Its great for learning, for understanding what is going
on and is helpful in designing speakers. The program is easy to use and intuitive.
The axis-symmetric assumption allows for partial analytical solution in 3D
which is quickening the calculation. Even if the actual problem is asymmetric
then approximate AxiDriver-models can give insights and clues about the
AxiDriver displays the near-field at a single frequency as contours,
which are overlayed by a sketch of the driver and its diaphragm. Further, the
application allows for broad-band analysis into plots of the spectra of the
sound pressure and radiation impedance with the help of
Vacs as a graphing server.
The acoustics is fully coupled to the mechanical rigid body mode of the driver.
The layout of AxiDriver is such, that after solving, the motor parameters can be
modified and the result is displayed immediately. For example, you can spin up and down
the Bl-factor and see the effect on the response almost in real time.
