Optimizing diaphragm behavior through simulations and measurements
The diaphragm (or membrane) of the speaker/driver is what transforms the alternating magnetic field generated in the voice coil into the pressure variations known as “sound”. In most cases, the ideal diaphragm should convert the applied voltage into piston-like movements regardless of frequency and amplitude. This is no easy task since phenomena like breakups and rocking modes, material nonlinearities etc. occur in the real world. Being able to predict and measure these imperfections can speed up a design process significantly.
