Audio device and audio processing method

Abstract

The present disclosure provides an audio device and an audio processing method based on the charger cable. The audio device includes: at least two microphones configured to collect audio signals; and a microcontroller configured to, process the audio signals collected by the at least two microphones to generate one data stream; and when the audio device is connected to a computing terminal, send the data stream to the computing terminal, the data stream being further processed by the computing terminal to perform an action. Each of the at least two microphones is respectively connected to the microcontroller.

Description

FIELD OF THE DISCLOSURE[0001]The present disclosure relates to the field of smart hardware technologies and, more particularly, relates to an audio device and an audio processing method based on the audio device.BACKGROUND[0002]Human-machine interaction during vehicle driving is an important technical issue. Today, portable electronic devices like mobile phones becomes more and more popular the gateway for this interaction by playing two distinct roles at a time: with the help of various navigation apps downloading on-line maps and real-time traffic data base, it acts as the navigation assistant for the driver while it remains the access point for the same driver to the IM apps where he / she communicates with the correspondents and receives notifications. A long existing problem for this usage is that interactions with the mobile phone attract the attention of the driver which need to be highly concentrated on road, and this conflict gets worse when the driver need to adjust the navi...

AI Technical Summary

Benefits of technology

[0008]Another aspect of the present disclosure provides an audio system. The audio system includes an audio device and a computing terminal. The audio device includes at least two microphones configured to collect audio signals and a microcontroller. Each of the at least two microphones is respectively connected to the microcontroller. The microcontroller is configured to process the audio signals collected by the at least two microphones to generate one data stream; and when the audio device is connected to the computing terminal, send the data stream to the computing terminal. The computing terminal is configured to decode the data stream and reconstruct the audio signals, perform one or more multi-input audio processing schemes to obtain one or more enhanced audio signal, and perform an action based on a result of voice recognition of the enhanced audio signal.

Problems solved by technology

Human-machine interaction during vehicle driving is an important technical issue.

A long existing problem for this usage is that interactions with the mobile phone attract the attention of the driver which need to be highly concentrated on road, and this conflict gets worse when the driver need to adjust the navigation destination / choice according to its communication on IM apps.

As a result, most drivers have the need and / or experience of manually operating the mobile phone while driving or waiting for a green light, which poses great security risk.

Although many countries have established laws that prohibit this type of behavior, due to its inherent needs, such behavior is very difficult to be completely avoided and sometimes can cause serious accidents.

However, such configuration often cannot provide as many various functionalities and convenience as driver's own mobile phone does, which does not solve the fundamental problem.

Nevertheless, its cost remains considerable due to the necessity of embedded high-performance processor and / or communication module for the voice recognition, and a stand-alone device requires a dedicate power supply for itself, not always available in the vehicle.
