AI Technical Summary
The microphones of existing wearable devices are affected by wind noise in high wind conditions, resulting in a decrease in recording quality and failing to meet the needs of outdoor sports or windy weather.
Design a wind noise reduction device, including a support structure, a receiving groove, a first acoustic damping structure, a first air layer, a second acoustic damping structure, and a second air layer. Combine high acoustic damping material and a waterproof layer to form a compact structure that effectively blocks and weakens the impact of wind noise, and offsets wind pressure fluctuations through the phase difference of the air layers.
Significantly reduces the impact of wind noise on the microphone sensor, improves recording quality, maintains the device's small size and portability, is suitable for outdoor environments with strong winds, and enhances user experience and recording stability.
