On May 20th to 21st, our CEO Ferruccio Bottoni held a keynote speech at the Materials Physics and Materials Science Conference in Vienna. Here’s the presentation: Find the presentation also on Google Slides.
Below a typical frequency response of a Megaclite earpiece is shown. The origins of the various peaks are explained:
The THD peak at ~10 kHz stems mainly from a mode of the MEMS at 21 kHz. When the MEMS is excited with 21kHz it resonates strongly and produces movement and subsequently a higher SPL. Due to small inherent non-linearities in the movement of the MEMS, 10.5 kHz will produce a small frequency component at 21 kHz which resonates and
How USound measures Ganymede MEMS speakers USound specifies and measures Ganymede MEMS speakers, Achelous and Adap, in both acoustic domains: in the Baffle and in the Coupler (artificial ear). For both setups, proprietary measurement adapters are used to fit the standardised setup. In the case of the baffle, the measurement adapter places the MEMS speaker with appropriate sealing inside the
