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.

News, Press & Publications

14.12.2020 - We are publicized in the January edition of the audioXpress magazine.

In the article "Electrostatic Pure Silicon Microspeakers for Wireless Earbuds" of the audioXpress magazin January 2021 edition we explore how smart earbudes provide voice-controlled access to advanced Internet services. Read more about how our MEMS microspeaker, based on CMOS-compatible materials and manufacturing processes, is contributing to the next generation of wireless earbuds and how we apply pure silicon technology to create sound from the smallest of volumes.

01.12.2020 - We are one of the 22 WINNERS in the Deep Tech Programme 2020!

We are honored to be selected by the Expert Jury of VC and corporate investors as one of the 22 best-scored companies of the Tech Tour Deep Tech Programme 2020. As winner of the Deep Tech Programme we will participate at the World Tour in March 2021.

Tech Tour brings startups and a network of leading entrepreneurs, service providers and actors from the world of high technology and investors together to create a Europe-wide network, to exchange ideas and to promote young, dynamic companies.

06.11.2020 - Arioso Systems awarded as the most exciting Hardware & Systems Startup for Deep Tech 2020.

Arioso Systems have been chosen by the prestigious TechTour as one of the 15 most exciting Hardware & Systems Startup for the Deep Tech 2020. TechTour is an exclusive club of startups selected by an experienced deep tech investor panel and one of the key Deep Tech Startup events in Europe. Our goal is to build a network with the leading entrepreneurs, investors and industry players from the world of high technology and to exchange ideas with them. As part of the TechTour Deep Tech 2020 program, which includes various investment and partnership opportunities, we will take part at the Opening Tour on the 17th November at 5 p.m. CET, the pitching session on 25th November between 2-4 p.m. CET and the online One2Ones on 30th November.

06.11.2020 - Arioso Systems at TechDay Online 2020.

We are honored to be selected for the TechDay Online 2020 event by the STEP USA program of the German American Chamber of Commerce. TechDay is one of the largest yearly events where startups from many sectors encounter, present themselves and meet investors. We will participate at this year’s TechDay Online 2020 during the three days 17th (from LA), 18th (from NY) and 19th (from London) of November.

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.

16.10.2019 - Arioso Systems at High Tech Venture Days in Dresden. Read more in an article by Sächsische Zeitung.
