  —Spatial Audio: Incorporates sensor fusion technology to achieve precise synchronization between head movements and spatial audio, creating an immersive auditory experience.

In response to the post-pandemic trend of hybrid work, the development team addressed common pain points in remote meetings—such as "limited video field of view" and "audio distortion"—by creating an "all-scenario immersive video conferencing system." Through deep hardware-software integration, it bridges the gap between remote and in-person participants, enhancing
communication efficiency and engagement.

• Smart Panoramic Vision and Precise Tracking
  —Seamless Panoramic Stitching: Utilizing an optimal three-camera configuration that balances cost and image quality to achieve a panoramic, blind-spot-free field of view.

  —International Standards: Complies with Microsoft Teamsʼ rigorous certification  standards, ensuring high reliability  for enterprise-grade communication.
• Premium Acoustic Design and Robust Protection
  —High-Quality Audio Capture and Output: Equipped with dual MEMS microphone acoustic channels and speakers with optimized electromagnetic structures, delivering high signal-tonoise ratio (SNR) omnidirectional audio capture and low-distortion sound in compact spaces.
  —Cutting-edge Encapsulation Technology: Utilizes a specialized encapsulation process to effectively block audio interference,ensuring crystal-clear calls.
  —Comprehensive Weatherproof Protection: With IP67-rated dust and water resistance, it significantly enhances the deviceʼs operational stability and durability across various environments.

In response to the complexity of "Mechanical  Layout" and the demand for lightweight design in smart glasses, MERRY has developed a "directional microphone module" that integrates two types of microphones, successfully overcoming the size constraints posed by current "Beamforming" technology.

• Innovative Features:
  —Innovative Co-chamber Design (Material Reduction): Through optimization via finite element analysis (FEM) simulation, MERRY
  has successfully moved beyond traditional independent chamber designs to achieve "co-chamber integration" for omnidirectional and bidirectional microphones. While maintaining
  98% of performance, the moduleʼs length has been reduced by 20%, significantly saving internal space and contributing to product light weighting.
  —Low-Power Algorithm (Extended Battery Life): Compared to traditional multi- microphone arrays, this technology leverages
  the complementary physical characteristics of the two microphones to achieve excellent directional sound pickup with only low-power weighted calculations. This effectively reduces the computational load on the chip, extends device battery life, and reduces the frequency of charging and energy consumption  for electronic products.
