Description

Technical Field

[0002] With the continuous development of wireless audio transmission technology, especially in scenarios such as meetings, live broadcasts, and audio recordings, wireless microphones have become common audio acquisition devices. However, existing wireless microphone devices usually lack an intuitive real-time status feedback system, making it difficult for users to quickly understand whether the device is currently working or whether there are any abnormalities. Especially in a multitasking environment, the synchronous feedback of the status of audio devices and audio transactions is crucial for the user experience.

[0003] The feedback method of traditional wireless microphones usually relies only on a single LED indicator light, which often cannot provide comprehensive feedback information. Especially in complex audio transaction processing, it is difficult to meet the user's precise perception requirements for the device status. To improve the user experience, there is an urgent need for a new type of intelligent feedback system that can dynamically feedback to users according to the device status and task changes during audio transmission. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to propose a method and device for audio transmission reminder between the receiving end of a wireless lapel microphone and a mobile phone end. By establishing an intelligent transaction perception engine between the receiving end and the mobile phone end and combining a multimodal interaction device, a comprehensive perception and feedback of audio status, audio transactions, and device status are realized. The system can provide real-time intelligent reminders through the stroboscopic light, color change of the LED light source, and a tactile feedback mechanism to help users better understand the current device status.
