Loudspeaker Abnormal Sound Classification Using Auditory Perception Weighted by Energy Entropy
IEEE Access, 2023 In order to improve the classification accuracy of loudspeaker abnormal sounds, this paper proposes a method based on time-varying specific loudness weighted by energy entropy and principal component analysis.

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 ...

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 ...

Electrostatic graphene loudspeaker [PDF]
Applied Physics Letters, 2013 Graphene has extremely low mass density and high mechanical strength, and key qualities for efficient wide-frequency-response electrostatic audio speaker design. Low mass ensures good high frequency response, while high strength allows for relatively large free-standing diaphragms necessary for effective low frequency response.

Time-Domain Sound Field Reproduction with Pressure and Particle Velocity Jointly Controlled
Applied Sciences, 2021 Particle velocity has been introduced to improve the performance of spatial sound field reproduction systems with an irregular loudspeaker array setup. However, existing systems have only been developed in the frequency domain. In this work, we propose a
