Charging case, method and audio playback kit for wireless communication

Abstract

The embodiment of the present disclosure discloses a charging box for wireless communication, a method for wireless communication with an audio playback device, and an audio playback kit for wireless communication. The charging box includes: a wired communication connector configured to: via a wired connection with an audio interface of a smart device including a non-real-time operating system, directly receive the first audio data for transmission to an audio playback device from the smart device. Audio data; a wireless communication unit configured to transmit second audio data to the audio playback device; a processor configured to execute a real-time operating system to achieve the following operations: according to the format of the second audio data to be transmitted The received first audio data is encoded, and the encoded second audio data is transmitted to the wireless communication unit. As a transmission relay between the smart device and the audio playback device, the charging box of the embodiment of the present disclosure can realize high-speed transmission and real-time processing of audio data, and can effectively reduce time delay.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, and more particularly, to a charging box for wireless communication, a method for wireless communication with an audio playback device, and an audio playback kit for wireless communication. Background technique [0002] With the progress of society and the improvement of people's living standards, earphones have become an indispensable daily necessities for people. Traditional wired earphones are connected to smart devices (such as smartphones, laptops, tablets, etc.) through wires, which will restrict the wearer's movement, especially in sports situations. At the same time, the winding and pulling of the headphone cable, as well as the stethoscope effect all affect the user experience. Ordinary Bluetooth headsets cancel the connection between the headset and the smart device, but there is still a connection between the left and right ears. [0003] True wireless earphones without...

Problems solved by technology

However, since the systems of smart devices are generally non-real-time operating systems, they are often interrupted by other tasks for a long time. At this time, in order to keep the audio processing uninterrupted, it is necessary to configure a large cache for each audio processing, resulting in a large delay , which makes it difficult for wireless headphones to achieve low-latency playback, which affects the playback effect

Especially in scenarios that require high real-time sound, such as when playing games on smart devices, the audio played by the wireless headset will lag behind the game action and game video, which seriously reduces the user experience.
