Wind noise prevention equipment and design method

Abstract

The invention discloses wind noise prevention equipment, relates to the field of wind noise treatment, and solves the problem of how to reduce wind noise formed when irregular airflow impacts the equipment. The wind noise prevention device 100 comprises a first woven mesh 101, a second woven mesh 102, a device housing 103 and a structural member 104. And the equipment shell 103 is provided with a pickup hole 1031. The first woven mesh 101 covers the pickup hole 1031. The pickup hole 1031 is provided with a structural member 104. The structural member 104 is connected to the device housing 103 to form a cavity. The structural member 104 is provided with a sound transmission hole 1041. And the second woven mesh 102 covers the sound transmission holes 1041. And the microphone is arranged at the sound transmission hole 1041. Due to the structural characteristics of the pickup hole 1031, the first woven mesh 101, the structural member 104 and the second woven mesh 102, the energy of wind noise can be suppressed, and the wind noise contained in an audio signal received by the microphone from the sound transmission hole 1041 is effectively reduced.

Description

technical field

[0001] The present application relates to the field of wind noise treatment, and in particular, to a wind noise prevention device and a design method. Background technique

[0002] Generally, when a user is in an environment of flowing airflow, when the user uses an electronic device carrying a microphone, the flowing airflow will hit the electronic device, causing the electronic device to receive pressure pulsations, and the time-varying pressure pulsations form wind noise. The wind noise signal received by the microphone is transmitted to the human ear through the speaker, and the user hears the noise. At present, the components used to prevent the microphone diaphragm from being affected by a large sudden pressure change have little effect on the continuous pressure pulsation with low intensity generated by the airflow, and cannot effectively suppress wind noise. Therefore, how to reduce the wind noise caused by the irregular airflow impacting the electro...

Embodiment Construction

[0044] The wind noise prevention device provided in this application is applied to include but not limited to earphone products, mobile phones, tablets, portable computers and wearable devices (such as watches, glasses, etc.) with functions of calling, audio positioning and noise reduction, etc. The specific form of the electronic device including the wind noise prevention device is not limited. When the user is in an environment with external air flow, when the user picks up the audio signal containing wind noise with the wind noise prevention device, the structural features of the wind noise prevention device and the woven mesh can suppress the wind noise energy, and the audio signal passes through the structure. After weaving the net, the wind noise energy contained in the audio signal received by the microphone is smaller than the wind noise energy at the pickup hole of the wind noise prevention device. Therefore, the wind noise prevention device provided by the present app...
