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 ...

Evaluating the onset conditions of a thermoacoustic Stirling engine loaded with an audio loudspeaker
Frontiers in Thermal Engineering, 2023 This paper aims to evaluate the onset conditions of a thermoacoustic Stirling engine loaded with a commercially available audio loudspeaker. The thermoacoustic engine converts supplied heat power into mechanical power in the form of sound, without any ...

Optimized Driver Placement for Array-Driven Flat-Panel Loudspeakers
Archives of Acoustics, 2017 The recently demonstrated ‘modal crossover network’ method for flat panel loudspeaker tuning employs an array of force drivers to selectively excite one or more panel bending modes from a spectrum of panel bending modes.

IEEE Transactions on Magnetics, 2007 We note the drawbacks of classical loudspeaker motors: the inductance varies with the coil's position, there is a reluctant effect and Eddy currents appear because of the iron in the motor. We then present ironless structures of loudspeaker motors to eliminate these drawbacks.

Driver Filter Design for Software-implemented Loudspeaker Crossovers
Archives of Acoustics, 2014 A hybrid method is presented for the integration of low-, mid- and high-frequency driver filters in loudspeaker crossovers. The Pascal matrix is exploited to calculate denominators; the locations of minimum values in frequency magnitude responses are ...
