AI Technical Summary

Technical Problem

Existing wireless headphones, particularly those using Bluetooth Low Energy (BLE) connections, suffer from high latency issues when used as wireless microphones, making them unsuitable for real-time audio applications like live streaming or performance scenarios.

Method used

Implement a data processing method for wireless headphones to operate in a wireless microphone mode using a dongle device that establishes a higher latency wireless connection, bypassing speaker signals, and transmitting audio signals directly to a user device for real-time audio capture and transmission.

Benefits of technology

Enables wireless headphones to function as high-fidelity wireless microphones without dedicated equipment, reducing latency and ensuring seamless audio signal collection and transmission.

Abstract

A data processing method for a wireless headphone, corresponding wireless headphone and computer program product are provided. The data processing method includes: in response to an operating mode of the wireless headphone set as a wireless microphone mode from a wireless headphone mode, using one or more microphone of the at least one microphone to collect an audio signal; transmitting the collected audio signal to a user device through a first wireless connection with a dongle device in the wireless microphone mode, the dongle device being plugged into the user device, wherein the first wireless connection has lower transmission latency than that of a second wireless connection between the wireless headphone and the user device in the wireless headphone mode; receiving, in the wireless microphone mode, from the user device through the first wireless connection with the dongle device, a speaker signal corresponding to the audio signal, and bypassing the speaker signal.
