Windproof processing method for intelligent voice equipment, windproof structure and intelligent voice equipment with the same structure

Abstract

The invention discloses a windproof processing method for an intelligent voice device, which comprises the following steps: arranging a hollow body whose height is adapted to the microphone sound collecting channel and connected with the sound collecting hole of the casing in the microphone sound collecting channel; The end of the direction; the windproof filler is filled inside the hollow body, so that the hollow body forms a sealed space in the microphone sound collection channel. The invention also discloses a windproof structure formed based on the above method and an intelligent voice device using the same. According to the solution disclosed in the invention, the physical windproof effect based on the internal structure design can be realized, the audio signal and call quality can be ensured, and it can be widely used for various smart portable / wearable voice devices.

Description

technical field [0001] The invention relates to the technical field of voice denoising, in particular to a windproof processing method for intelligent voice equipment, a windproof processing structure for intelligent voice equipment, and an intelligent voice equipment with the structure. Background technique [0002] Today, portable and wearable devices, such as watches, earphones, mobile phones, tablets and other smart devices with voice functions are becoming more and more popular. With the rapid development of voice technology, the demand for voice functions of these smart devices is also increasing. However, in the application process of intelligent voice, the collected noise will seriously affect the effect of the voice function and user experience. Among the many noises, wind noise is a very typical and common noise interference in outdoor scenes. Therefore, in order to reduce the interference of wind noise on the collected voice quality, methods such as windproof co...

Problems solved by technology

Therefore, in order to reduce the interference of wind noise on the collected voice quality, methods such as windproof cover / cover, windproof membrane, and front-end algorithm are usually used for denoising processing, but these existing methods have their own defects in the application process: Due to its structural characteristics, the windproof cover / cover can only be applied to voice equipment with a slender structure, such as a headphone microphone board. For voice equipment with a non-slender structure such as watches and tablets, it will not be possible to install suitable or seriously affect the industrial design. Beautiful; although the windproof membrane is installed inside the structure without affecting the appearance, its windproof performance is poor. At low wind speeds such as 5-10km / h, there is only 1-2dB attenuation, and the windproof effect is basically lost at slightly higher wind speeds; while the front-end algorithm It is to perform high-pass filtering, noise reduction and other processing to suppress low-frequency wind noise at the signal level collected by the microphone, which cannot solve the problems of signal truncation and negative signal-to-noise ratio caused by wind noise, and in this processing method, the low-frequency frequency response It will attenuate many decibels, so that the collected speaker's voice signal is obviously distorted, thus affecting the effect of the voice function
