R&D Stories: Using Multiphysics Simulation for an Electrovibroacoustic Analysis of a Balanced Armature Transducer

This article explains how multiphysics modeling and simulation can be used to analyze electroacoustic transducers. Using a balanced armature transducer as example, the analysis combines the electromagnetic field with structural vibrations and acoustic radiation using multiphysics coupling features. A moving mesh is also used to model the back Electromotive Force (EMF).

R&D Stories: The Role of Resonance in Audio Clarity

Years of research conducted by ClarityCap, the audio capacitor manufacturer, and the UK-based Institute of Acoustics at the University of Salford, explored how the resonance from the body of a capacitor in a loudspeaker crossover circuit has an audible impact on sound quality. The article details the extensive testing, measurements, and conclusions, which allowed ClarityCap to perfect its manufacturing process, minimizing resonances in capacitors.

R&D Stories: Developing an Electrostatic Transducer

This article discusses how Warwick Audio Technologies designed a completely new type of transducer for high-end electrostatic headphones using the latest materials, validated with computer simulation tools from Comsol. The design process for the High-Precision Electrostatic Laminate (HPEL) transducer was first available in the outstanding Sonoma Model One, the world’s first headphones to use HPEL audio transducers, and all subsequent Warwick products, now expanding also to automotive applications. This article was originally published in audioXpress, April 2018.

R&D Stories: Using Ultra-Wideband Technology for Wireless Delivery of Audio and Multimedia

February 9, 2023 by Frederic Nabki, Nicolas Paillusseau, and Ronald Rinkenbach

R&D Stories: Using Ultra-Wideband Technology for Wireless Delivery of Audio and Multimedia

In this exclusive article for audioXpress, Frederic Nabki, Chief Technology Officer, Nicolas Paillusseau, Applications Manager, and Ronald Rinkenbach, Applications Engineer, all from SPARK Microsystems, address the advantages of using Ultra-Wideband (UWB) technology to achieve high-quality wireless audio streaming and how UWB radios can be deployed effectively as a high speed and low latency data communication method demonstrating compelling advantages.

R&D Stories: How to Choose the Right Signal Processing Technique

R&D Stories: How to Choose the Right Signal Processing Technique

The Chief Science Officer at AudioTelligence discusses the merits and challenges of using beamforming and blind source separation techniques to correctly process voice sources from the audio signals picked up by microphones in real-world situations. This article explains how these signal processing techniques can help deal with the noises that make it difficult to pick out and clearly hear voice, and how to obtain clean audio signals picked up by microphones contaminated with interference, noise, and reverberation. This article was originally published in audioXpress, November 2022.

R&D Stories: Design and Development of the Holoplot X1 Matrix Array

Many product designers and manufacturers in the audio industry the world over have been making huge leaps forward in hardware, software, and interoperability that they have been largely unable to show off thanks to a disruption to live events. Following the return of trade shows in 2022, the lid has been lifted on a whole host of innovations in the pro audio space, and among them Holoplot has emerged as a standout with its X1 Matrix Array sound system. This is an inside account about how the Holoplot team has been pushing the boundaries of what is possible in the pro audio space.
