Loudspeaker panels, such as distributed mode loudspeakers (DML), are a promising alternative approach in loudspeaker design. DML have many advantages compared to pistonic loudspeakers. However, the frequency response is mostly associated with higher deviations. The position of the excitation is one parameter to optimize the frequency response. An electro-mechanical-acoustical model is presented that enables the optimization of the exciter location, based on the response of the radiated sound power. A simulation model is presented for different surface areas and aspect ratios of the panel. The appropriated positioning and its excitation are discussed based on a single criterion and finally compared with the State of the Art method.
