SFX Technologies Ltd.SFX Technologies Ltd. is using COMSOL Multiphysics to design a new type of loudspeaker driver that uses virtually any surface to produce high-quality sound. ...
WIDEX A/SA privately-owned company with a world market share of approximately 10%, Widex launched the world’s first fully digital CIC (completely in the canal)...
This is a model of a loudspeaker of the dynamic cone driver type, common for low and medium frequencies. The model analysis includes the total electric impedance and the on-axis sound pressure level at a nominal driving voltage, as...
The Bessel panel is a way to arrange a number of loudspeakers so that the angular sound distribution resembles that of a single speaker. This model combines five Bessel panels in the same pattern to approximate a purely radial sound...
A piezoelectric transducer can be used either to transform an electric current to an acoustic pressure field or, the opposite, to produce an electric current from an acoustic field. These devices are generally useful for applications that...
This example models the acoustic behavior of a woofer mounted in a bass reflex enclosure and placed in the corner of a room. One of the most important design parameters for a loudspeaker driver is its sensitivity as a function of the...
