Pioneering scale-up manufactures optical MEMS microphones which show first-class sound high quality at just some millimeters in measurement.
SINGAPORE, Feb. 26, 2024 /PRNewswire/ — Sennheiser, along with present traders, is investing 7 million euros within the Norwegian scale-up enterprise sensiBel. The corporate has developed optical MEMS microphones which show first-class sound high quality regardless of their miniature measurement. The miniature microphones allow a totally new and improved expertise in utility areas equivalent to shopper electronics, automotive, conferencing options, and medical units.
Always constructing the way forward for the audio world and creating distinctive sound experiences – that’s the aspiration that drives the Sennheiser Group. Pushed by this intention, the family-owned firm is additional increasing its robust place as a supplier {of professional} audio options. “We wish to develop sustainably as an organization. Along with investments in our present enterprise, this additionally contains investments in promising future fields outdoors of our firm, offering these align properly to our firm and our imaginative and prescient,” explains Co-CEO Daniel Sennheiser. Andreas Sennheiser provides: “sensiBel’s modern optical MEMS expertise is clearly this kind of promising rising area. As traders, we stay up for actively driving ahead this groundbreaking improvement.”
sensiBel has developed a miniature microphone utilizing optical expertise that permits a generational shift in MEMS microphone efficiency, which is now sampling with lead prospects. “sensiBel shares the identical imaginative and prescient as Sennheiser and we’re proud to welcome Sennheiser as investor,” says sensiBel CEO Sverre Dale Moen. He continues: “We imagine an funding from such a extremely acknowledged audio firm speaks of the deserves of the expertise and the potential for optical MEMS expertise to form the way forward for miniature microphones.”
MEMS Microphone by sensiBel
The distinctive characteristic of sensiBel’s distinctive expertise is using mild waves to measure the motion of the diaphragm. In contrast, standard MEMS microphones measure an electrical area between the transferring diaphragm and a backplate. In sensiBel’s optical system nevertheless, a laser generates mild beams which are projected onto the microphone membrane and mirrored on a photograph detector. The mirrored beams are captured and processed in an Utility Particular Built-in Circuit (ASIC) with a digital output knowledge interface. In distinction to the traditional methodology, this new expertise makes it attainable to measure very small actions and due to this fact seize very low noise ranges – even when there’s a excessive stage of loud background noise. Moreover, the optical MEMS microphone can stand up to excessive sound stress ranges offering a big dynamic vary to the customers. Consequently, the microphones generate considerably higher sound high quality than earlier MEMS options in the marketplace – with a specification of 80 dBA SNR (14 dBA noise flooring), 132 dB dynamic vary, 24-bit digital output, and with low energy consumption, whereas being simply as compact.
