Ananke: Our evaluation kit for MEMS speakers

/ USound/ 0 comments

Ananke is an evaluation kit made specifically to let you discover what USound’s piezo MEMS speakers sound like. This evaluation kit is your first step into the world of MEMS speakers, allowing you to test and experiment with MEMS speakers and customised audio filters. To access the filters, delays, routing and GPIO functions, we recommend you to use SigmaStudio (download

Why do MEMS speakers have such a high THD peak at 10 kHz?

/ FAQ/ 0 comments

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 to measure Ganymede MEMS microspeakers

/ FAQ/ 0 comments

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
