Lyra is a pair of hearing aid glasses that joins hearing support with everyday eyewear. A six microphone array captures sound from a selected direction and reduces background noise. A rotatable speaker sits close to the ear canal and provides up to 40 decibels of gain for clearer speech. Adaptive noise reduction and feedback control help in complex sound environments. Lenses can be made for myopia, presbyopia or progressive correction. The intent is to give hearing support a non medical appearance suited to daily use.
Press Kit
- Unique Properties
- Lyra integrates professional hearing-aid tech with consumer smart glasses, breaking traditional hearing aids' 'medical device' limitation. Core configs: 6-array directional mic (accurate pickup and noise reduction), rotatable ear canal-proximal speaker (40dB max gain for clarity), with adaptive noise reduction and acoustic feedback algorithms for complex sound fields. Supports myopia/presbyopia/progressive lens customization, delivering 'hearing and vision and daily wear' all-in-one experience.
- Dimensions & Packaging
- 155 x 168 x 35 mm
- Tags
- Smart glasses, Hearing aid function, Wireless charging, Acoustic tuning, Rotating speaker.
- Production Technology
- Temples: 0.8mm TR90 injection molding. Electronics: multilayer FPC, SiP with Bluetooth SoC & PMIC, LDS antenna, custom-shaped micro battery. Assembly: active alignment for optical engine & waveguide, adhesive sealing (IP56), fixture press-fitting.
- Design Challenge
- Wireless charging alignment: custom coil misalignment reduces efficiency; magnetic positioning + multi-coil array + Q-value detection for adaptive matching. Acoustic tuning: open-ear speaker has sound leakage & weak bass; dual-diaphragm inverted cavity + psychoacoustic EQ + bone conduction assist, anechoic chamber optimization.
- Project Duration
- Launched in Shenzhen, June 2025; now in prototype testing.
- Inspiration
- The design inspiration comes from hearing-impaired users' pain points: existing hearing aids have single functions (no multimedia connection) and medical-like looks, making users reluctant to wear them daily. Thus, we focus on 'non-medical and multi-functional', using a rotatable speaker (better clarity), 4 scenes and 4 hearing presets, and a stylish glasses design to make the device effective and integrated into daily life.
