One-Dimensional Haptic Rendering Using Audio Speaker with Displacement Determined by Inductance
Machines, 2016 We report overall design considerations and preliminary results for a new haptic rendering device based on an audio loudspeaker. Our application models tissue properties during microsurgery.

The Effect of Interchannel Time Difference on Localisation in Vertical Stereophony [PDF]
, 2015 Listening tests were conducted in order to analyse the localisation of band-limited stimuli in vertical stereophony. The test stimuli were seven octave bands of pink noise, with centre frequencies ranging from 125–8000Hz, as well as broadband pink noise.

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 ...

2D to 3D ambience upmixing based on perceptual band allocation [PDF]
, 2015 3D multichannel audio systems employ additional elevated loudspeakers in order to provide listeners with a vertical dimension to their auditory experience.

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.

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.

Developing and evaluating a hybrid wind instrument [PDF]
, 2014 A hybrid wind instrument generates self-sustained sounds via a real-time interaction between a computed excitation model (such as the physical model of human lips interacting with a mouthpiece) and a real acoustic resonator.

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.

Efficiency of low power audio amplifiers and loudspeakers [PDF]
, 2001 In this paper we look at the load presented to audio amplifiers by real transducers. We consider the power losses in Class-AB and Class-D amplifier topologies, and determine that in order to predict efficiency it is necessary to consider the amplifier ...
