Abstract: During the monitoring of the behavior of different types of exciters attached to the same loudspeaker panel, significant deviations of the upper-frequency limit were discovered. These deviations depend on the resonance of the voice coil former and cannot be explained with the linear T/S parameters. This paper shows the indirect and direct measurement of the voice coil’s break-up with two exemplary exciters. Furthermore, an FE-simulation model has been built to validate and visualize these break-up modes. Finally, a prototype with reinforced structure was constructed to increase the resonance frequency and to extend the frequency range of the loudspeaker panel.

AB - During the monitoring of the behavior of different types of exciters attached to the same loudspeaker panel, significant deviations of the upper-frequency limit were discovered. These deviations depend on the resonance of the voice coil former and cannot be explained with the linear T/S parameters. This paper shows the indirect and direct measurement of the voice coil’s break-up with two exemplary exciters. Furthermore, an FE-simulation model has been built to validate and visualize these break-up modes. Finally, a prototype with reinforced structure was constructed to increase the resonance frequency and to extend the frequency range of the loudspeaker panel.
