Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wind noise interference caused by external wind vortices affects the normal use and user experience of wearable devices like smart glasses, particularly in windy scenarios.
Innovation Solution
A temple design with a bent first sound pickup channel and fairing structure that attenuates wind noise by elongating the path of wind vortices, reducing pulsating pressure on the microphone, and incorporating independent sound pickup ports and channels to minimize noise interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a direct sound pickup channel is used to ensure clear sound transmission, then sound pickup quality is improved, but wind noise interference increases
Solution Approach 1:
The sound pickup channel is designed with a bent/curved structure instead of a straight line. The curved channel includes a first curved section and a second curved section that change direction, which weakens the transmission of pulsating pressure from wind vortices while maintaining sound transmission capability to the microphone.
Solution Approach 2:
The sound pickup channel transitions from a one-dimensional straight path to a multi-dimensional curved path with multiple direction changes. This spatial reconfiguration elongates the transmission path and introduces geometric complexity that attenuates wind noise while preserving acoustic functionality.
2Object-affected harmful factors
If a wind noise reduction structure is added to attenuate wind vortices, then wind noise is reduced, but device complexity increases
Solution Approach 1:
The wind noise reduction function is merged with the existing sound pickup channel structure. The bent channel design integrates the noise attenuation feature directly into the acoustic pathway, eliminating the need for separate wind noise blocking components while still achieving wind noise reduction.
Solution Approach 2:
The bent sound pickup channel serves multiple functions simultaneously: it transmits sound waves to the microphone and attenuates wind noise. This multi-functional design avoids adding separate dedicated wind noise protection structures, thereby reducing overall device complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively reduces wind noise signals picked up by the microphone, improving sound pickup quality and ensuring normal device function in windy conditions, while maintaining a simple structural design and reducing production complexity.
Implementation Method 1
wind vortices need to be transmitted to the microphone through the first sound pickup channel. The provision of the first sound pickup channel can attenuate wind noise signals entering the temple

AI summary
Embodiments of this application provide a temple, glasses, and a wearable device. A mounting wall surface is provided on an outer surface of a housing of the temple. An accommodating cavity configured to accommodate a microphone is provided in the housing. A fairing covers the mounting wall surface. At least one first sound pickup channel is formed between an inner surface of the fairing and the mounting wall surface. A first sound pickup port and a second sound pickup port that communicate with the first sound pickup channel are provided on at least one of the fairing and the housing. The provision of the first sound pickup channel can implement diversion and attenuation of wind noise signals entering the interior of the temple, thereby achieving a wind noise reduction effect, reducing wind noise signals picked up by the microphone, ensuring normal use of glasses and other devices in a windy scenario, and improving user experience. The first sound pickup channel is formed by covering the outer surface of the housing with the fairing. A structural design and layout inside the housing of the temple are not affected. The structural design is easy to implement, and reduces difficulty and costs for implementing a wind noise prevention design on the temple.
