MEMS-Voix 3

01 / Identity

Full control over Time Domain

Voix 3 takes the legacy of MEMS-3S 2025 and improves even further. Evolving from the isobaric chamber of the MEMS-3S 2025, the new Voix acoustic system giving the xMEMS Muir a defined role in the midrange and vocals, while the xMEMS Montara exclusively handles the super high frequencies.

02 / Sound + Voix

Where speech lives, the system flourishes.

Voix does not recreate pinna gain resonance. It changes how the driver is acoustically configured in the vocal-presence region, where voices carry most of their information. Muir’s own 12.2 kHz mechanical resonance is not shifted.

xMEMS Montara

Six cells. One silicon die.

Montara is built differently even by MEMS standards. Six individual piezoMEMS speaker cells are fabricated into one monolithic silicon transducer and move together as a single acoustic source. [CONFIRM: Montara's role in Voix 3]

Monolithic silicon · 6 speaker cells · 1 acoustic output

05 / Use · AP GO energizer

AP GO energizer, exclusively designed for monolithic silicon MEMS

Included in the package, a pocket-sized energizer with regulated DC bias of 9000 mV, driving Muir & Montara within its signal range. Plug in, listen.

  • Regulated DC bias≥ 9000 mV
  • Signal handlingup to 24 Vpp
  • FormPocket-sized
