Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] The invention provides an audio processing method for a smart head-mounted wearable device. The audio processing method includes the following processing steps:

[0040] Step S10: The stereo audio signal 100 is sent to the audio signal processing module 10 to perform full-band audio algorithm processing on the stereo audio signal 100. The audio algorithm processing includes equalization adjustment processing, dynamic processing, distortion compensation processing, phase processing, and surround sound enhancement. at least one of the processing, wherein the stereo audio signal 100 comprises a left channel audio signal 101 and a right channel audio signal 102;

[0041] Step S20: The stereo audio signal 100 processed by the sound effect algorithm is simultaneously sent to the first audio power amplifier circuit 20 and the second audio power amplifier...

Abstract

The invention provides an audio system and an audio processing method for an intelligent head-mounted wearable device. The audio system comprises an audio signal processing module, a first audio poweramplification circuit, a second audio power amplification circuit, a first frequency division circuit, a second frequency division circuit, a left channel first sound production device, a right channel first sound production device, a left channel second sound production device and a right channel second sound production device. The left channel audio signal and the right channel audio signal aresubjected to full-band sound effect algorithm processing through the audio signal processing module, then subjected to power amplification through the first audio power amplification circuit and thesecond audio power amplification circuit, then subjected to frequency division through the first frequency division circuit and the second frequency division circuit and played through the corresponding sound production devices, and the replay effect is achieved. According to the audio system, fewer hardware components can be adopted to form the audio system, and only two audio signal processing links are adopted to complete audio signal processing of each sound channel.

Description

【Technical field】 [0001] The invention belongs to the technical field of smart wearable devices, and in particular relates to an audio system and an audio processing method for smart head-mounted wearable devices. 【Background technique】 [0002] The application of smart head-mounted wearable devices has become more and more popular, and has a wide range of applications in many fields such as industry, medical care, education, and culture. Hearing is one of the main ways for people to interact with the outside world, so the sound playback function is a smart Indispensable on headsets. [0003] At present, in order to improve the overall sound quality of smart head-mounted wearable devices, such as smart head-mounted glasses, especially the low-frequency sound quality, the sound playback system will use micro-sounding devices to reproduce mid- and high-frequency sounds, and use bone conduction vibration devices to reproduce low-frequency sounds. sound. [0004] In the curren...
