Continental Speakerless Ac2ated Sound System and Sennheiser Software Power Morgan Sports Cars

The next generation of Morgan sports cars will benefit from Sennheiser’s software technology to deliver a quality sound experience to Morgan drivers. The partnership is supported by the technology developed by Continental with its speakerless Ac2ated Sound System, which is based on actuators that excite selected surfaces in the vehicle interior to produce sound. In comparison to conventional audio systems, Ac2ated Sound enables a reduction of weight and space of up to 90 percent.

Cambridge Mechatronics Announces Ultra-slim, High Precision Rotary Actuator

Cambridge Mechatronics, a leading British company and developer of Shape Memory Alloy (SMA) actuators has developed a new ultra-slim, high precision rotary actuator product. The actuator characteristics include lightweight design, two thousand step positions per revolution and it is completely non-magnetic so it can operate in areas of high magnetic flux that might otherwise exclude conventional motor technologies. With a low profile of around 1mm, it can be used in the most space-constrained applications.

Sound Solutions Austria Presents World's First Actuator Loudspeaker for Stereo Sound

The micro-acoustics experts at Sound Solutions Austria GmbH have developed a compact actuator that is able to ensure stereo sound quality when used to transform the display of increasingly thin smartphones and tablets into a loudspeaker. According to the Vienna-based company, the new “Singing Display” actuator is ideal for space-saving, waterproof designs, extending the response beyond what is possible with conventional speakers technologies, by being applied directly to the back of the large tablet or smartphone screen surfaces.

STMicroelectronics Establishes World’s First “Lab-in-Fab” to Advance Adoption of Piezoelectric MEMS in Singapore

STMicroelectronics, a leading manufacturer of Micro-Electromechanical Systems (MEMS) technology, announced a collaboration with A*STAR’s Institute of Microelectronics (IME), a research institute in Singapore, and ULVAC, a leading Japanese manufacturing-tool vendor, to jointly setup and operate an 8-inch (200mm) R&D line focused on Piezo MEMS technology within ST’s existing manufacturing facility in Singapore. The concept aims to advance the adoption of piezoelectric MEMS in new applications including augmented reality.

Bass Shakers (Part 2): Motion Platforms Are Bass Shakers on Steroids

Bass Shakers (Part 2): Motion Platforms Are Bass Shakers on Steroids

In the first part of this article, our exploration of bass shakers introduced us to haptic sensations, which add the dimension of structure-borne vibrational energy to audio reproduction. At a concert, we see the performers, hear the music, and feel the amphitheater resonate with the bass. For home theaters, this “tactile” component adds another dimension (sometimes referred to as 4-D) to reproduce the impact of explosions, engine sounds, and thunder through by use of vibration. In this article we will focus directly on those haptic components. This article was originally published in audioXpress, May 2014.
