The World’s First TRUE MEMS Microspeaker for:

TWS

In-ear

Over-ear

Replacement of Voice Coil Technology

Sealed-Ear

Full Bandwidth Speaker replaces single dynamic driver systems

Unsealed or Multi-Driver

Tweeter replaces 1 or more balanced armatures

Features

Montara, the industry’s first TRUE MEMS speaker, eclipses early hybrid-MEMS speakers by implementing the entire speaker (actuator and membrane) in silicon, reducing package height and eliminating driver matching and calibration due to inherent variability in traditional membrane assembly.

Through the combination of design innovation and monolithic capacitive piezo-MEMS manufacturing, Montara delivers a new level of performance, size, energy efficiency and uniformity not possible with traditional voice coil or hybrid MEMS approaches.

Sound Quality
  • Full bandwidth (20Hz-20kHz) with flat frequency response at 115dB SPL (sealed)
  • 0.5% THD (300Hz @ 94dB SPL)
  • Better SPL/mm3
Consistency
  • Highly uniform and reliable semiconductor process
  • Eliminates driver matching and calibration
Low Latency
  • <50µs group delay (mechanical latency) enables improved ANC of non-stationary noise
  • Near-zero phase delay increases maximum noise suppression of stationary noise
Robustness
  • Monolithic piezoMEMS 10,000g mechanical shock resistance
Longer listen times
  • Montara’s capacitive vs. current-driven architecture reduces driver power consumption
Water-proof
  • IP58 water immersion and dust resistance without special membrane
Implementation
  • World’s First SMT-ready microspeaker
  • Replace multiple balance armature drivers with a single chip
Small size
  • 50mm3
  • <1mm thickness
