Experimental Characterisation of a Flat Dielectric Elastomer Loudspeaker
Actuators, 2018 Conventional loudspeakers are often heavy, require substantial design spaces and are hard to integrate into lightweight structures (e.g., panels). To overcome these drawbacks, this paper presents a novel extremely flat loudspeaker which uses dielectric ...

Synthesis of soundfields through irregular loudspeaker arrays based on convolutional neural networks [PDF]
EURASIP Journal on Audio, Speech, and Music Processing, 2022 Most soundfield synthesis approaches deal with extensive and regular loudspeaker arrays, which are often not suitable for home audio systems, due to physical space constraints. In this article, we propose a technique for soundfield synthesis through more

Loudspeaker cabinet design by topology optimization [PDF]
Scientific Reports, 2023 Using material distribution-based topology optimization, we optimize the bandpass design of a loudspeaker cabinet targeting low frequencies. The objective is to maximize the loudspeaker’s output power for a single frequency as well as a range of ...

A LOUDSPEAKER ORCHESTRA FOR CONCERT HALL STUDIES
Auditorium Acoustics 2008, 2023 1-4 . These parameters, however, each provide only a single value computed from an impulse response. In concert halls, the impulse responses are often measured with an omnidirectional sound source and microphone. However, such a single source is far from

Optimal model-based beamforming and independent steering for spherical loudspeaker arrays [PDF]
in IEEE Trans. Audio, Speech, and Lang. Proc., vol. 19, no. 7, pp.
2234-2238, Sept. 2011, 2023 Spherical loudspeaker arrays have been recently studied for directional sound radiation, where the compact arrangement of the loudspeaker units around a sphere facilitated the control of sound radiation in three-dimensional space. Directivity of sound radiation, or beamforming, was achieved by driving each loudspeaker unit independently, where the ...
