Shin, Mincheol, Fazi, F., Nelson, Philip A., Lee, Sung Q., Lee, Hong-Yeol, Park, Kang-Ho and Seo, J. (2009) Illustration of source control methods for personalised sound field At Active 2009 Conference. 20 - 22 Aug 2009. 10 pp.

Record type: Conference or Workshop Item (Paper)


A control strategy is introduced to manage the acoustic radiation pattern of two small-size loudspeakers used in small-sizeaudio devices. Each loudspeaker is modeled as an imperfect dipole which has a slight irregularity that represents the introduced loudspeaker. An efficient source control method, acoustic energy difference maximization, is applied to obtain a radiation pattern for a personalised sound area with the proposed model. The dipole irregularities are also optimized in order to obtain a better radiation pattern. This paper shows the feasibility of practical implementation for the generation of a personalised sound area with just two stacked miniature loudspeakers
