AES Online Fall 2021
Recently introduced MEMS micro speakers target in-ear audio applications such as true wireless earbuds, hearables and hearing aids. A key requirement in these ultra-mobile applications is a high energy efficiency of the components. In our presentation at AES Fall Online 2021, you will learn why MEMS microspeakers claim this competitive advantage.
The most advanced approaches to MEMS speakers are based on capacitive transducer technology. In this contribution, we discuss some fundamental energetic relations that such electroacoustic transducers are subject to, and draw some implications for the requirements of a transducer that can operate at high efficiency.

MEMS World Summit EU
The MEMS World Summit EU in Munich brings together political, business, financial, research and industry leaders in the field of micro electrical mechanical systems. This world’s leading MEMS manufacturing gathering took place from 7th to 8th September. Our Head of MEMS Development, Holger Conrad explained why MEMS microspeakers made from 100% silicon are the best solution for audio reproduction in wireless in-ear headphones. In his presentation on 8th September at 4:25 p.m. CET, he showed balanced speaker designs and technology with improved linearity.
15. – 18. Aug 2021
The demand for wireless earbuds is increasingly shifting towards aspects beyond sound quality, such as comfort, increased battery life and integration with other electronic components. These factors impose tighter requirements in the power budget for the audio transducer.
At DAGA2021 our Head of Technical Marketing, Lutz Ehrig, answered the question of how MEMS speakers can become more powerful than moving-coil speakers and gain competitive advantage. During the online session “MEMS loudspeakers – where do we stand today?” we discussed some basic energetic relationships that such electroacoustic transducers are subject to and draw some conclusions from these relationships on the requirements for a transducer that can operate with high efficiency.

Fraunhofer reports about us
Our technology does everything differently from previous techniques. With this approach, we want to offer a new gateway into the digital world.
Our innovation: “We have virtually thrown overboard the central element of a loudspeaker, the membrane. Insted, we integrate many thin bending bars, similar to the strings of a harp, into a MEMS silicon chip. This gives us a large acoustic inner surface, but at the same time we can keep the outer surface minimal.”
Beside the innovation of our technology, you can read in the latest article of Fraunhofer magazine how our microspeakers emerged from a failed start and what are still planing. Click here to read the article in German.

We are featured in Handelsblatt
Europe is increasingly disappearing from the semiconductor world map.
In 2020, only 8.5% of the industry’s turnover was generated in Europe. Between 2015 and 2020, the industry grew globally by an average of 5.6% each year, in Europe by only 1.8%.
Our CEO, Jan Blochwitz Nimoth and two other Dresden-based start-ups are quoted from a conversation with Handelsblatt, explaining their chip innovations and the potential for Europe to stop this decline in global market share. Our goal is to become a globally leading chip design house, thus also contributing to the relevance of Europe.

180th Meeting of the Acoustical Society of America
Recently, a new approach for an all-silicon MEMS-based microspeaker has been presented for in-ear applications. The volume displacement is generated by multiple electrostatic actuated beams called “Nanoscopic Electrostatic Drives” (NED) that move in lateral direction between a top and a bottom silicon wafer. The top and the bottom wafers are provided with openings through which air can flow in and out.
Two fundamentally different actuator designs have been realized: An asymmetric electrostatic pull-actuator and an electrostatic push-pull actuator.
While the push-pull actuator can be actively displaced in both directions, the pull actuator can only be displaced actively in one direction and therefore requires an offset voltage to oscillate around a working point. These different driving schemes have a major impact on stability and harmonic distortions.
These two approaches implemented for MEMS loudspeakers were compared and the impact on acoustic performance was demonstrated by our Head of Technical Marketing, Lutz Ehrig in his presentation “From Single-Ended to Push-Pull Electrostatic MEMS Speakers for In-Ear Audio Applications” on 9th June at the conference Acoustics in Focus of the ASA.

Interview with Mergermarket
On March 25, we participated at Tech Tour Future 21. Our successful participation was also noted by major financial intelligence platform Mergermarket. Following an interview with our Managing Director, Jan Blochwitz-Nimoth, Mergermarket published an article highlighting our growth, financing strategies as well as our objectives.
Our CEO reported among other things on our preparations for Series A: “[Our] company is interested in raising the funds from venture capital firms with expertise in deep tech and with deep pockets […].”
When asked if we would also welcome US investors, Jan Blochwitz-Nimoth confirmed we would, “both to broaden [our] Europe-centric ownership and because a large proportion of [our] customers is in the region […].” We plan to be more active in discussions with investors in the third quarter of this year, therefore we are looking for interested parties. Our aim is to complete our Series A in the first half of 2022.
Jan also said, “[we] plan to use the new capital to further develop [our] micro-speaker chip and prepare to commercialize it in 2024.”
Our goal is to become the number one provider of micro speaker technology for the ultra-mobile audio world. The article also explained that our microspeakers are easily scalable for mass markets, because they are CMOS compatible and thus widespread MEMS production capacities can be used.

Arioso Systems at Tech Tour Future21
As an award winner of the Tech Tour Deep Tech Programme 2020 in the category Hardware & Systems, we were honored to participate at Tech Tour Future21. Our goal is to exchange and network with Europe’s leading tech entrepreneurs and investors. Furthermore, we would like to extend the circle of our investors.
Tech Tour Future21 was taking place from 24th till 26th of March 2021.

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.
