Electrostatic Actuation

The sound generating beams consist of three electrodes. Between these electrodes an electrostatic field causes a force along each beam and an in-plane deflection. We call this Nanoscopic Electrostatic Drive (NED). Read more about NED in Nature Communications.

Sound Generation Inside the Chip

Dozens or even hundreds of sound generating beams – arranged between a top and a bottom wafer – are moving according to an audio signal. The sound is released through holes in a top and a bottom wafer. Since the "muscles" that drive the beams are contained in each beam, an incredible variety of chip designs is possible.

01.10.2020 - Arioso Systems at Virtual AES Show Fall 2020.

At the AES Show Fall 2020 we will present our latest developments in our electrostatic all-silicon MEMS µSpeaker technology. Our Head of Technical Marketing & New Business Development Lutz Ehrig will show measurement results of a new actuator design enabling significantly reduced harmonic distortion ratios. At the same time higher sound pressure levels are achieved due to increased actuator displacement and higher actuator count per chip area. This is a unique feature of Arioso’s µSpeaker technology since the sound is generated by the in-plane movement of hundreds of silicon cantilever beams. The presentation will be part of the technical program in the last week of the show. Watch our on demand paper presentation about our balanced electrostatic all-silicon MEMS Speaker from the 27th till the 30th of October here.

27.08.2020 - Arioso Systems Accepted for Soundtech Accelerator Program in Struer, Denmark.

Arioso Systems has been accepted to participate in the program of one of the European leading seed accelerators. During the international, six months program Arioso Systems gets access to the existing expertise of crucial players in the audio industry. In the first of three camps Arioso Systems elaborates strategic topics and value proposition for its silicon-based µSpeakers. Intensive trainings in tailormade workshops give a gateway to develop the business potential of µSpeaker to the maximum. In addition, networking with product specialists from the most reputable Danish sound industry grants Arioso Systems access to the market of wearable audio devices. In addition, Soundtech professionals also share their knowledge of how to distribute and digitally market products professionally. Accompanying the process, Arioso Systems profits from highly specialized skills of Accelerace and the Sound Hub Denmark based on coaching and exchange sessions.

02.04.2020 - Arioso Systems GmbH is financed and can starts to operate. Read more in our press release: English version and German version.
