Description

Technical Field

[0001] This utility model relates to the field of karaoke entertainment equipment technology, and in particular to a portable karaoke entertainment system. Background Technology

[0002] Karaoke entertainment has always been popular, from dedicated KTV venues to home karaoke devices in every household. With the continuous development of network technology, karaoke apps based on PCs or mobile phones have further diversified the forms of karaoke entertainment. Early home karaoke devices primarily consisted of a combination of a television, speakers, microphone, and DVD / VCD players. However, DVDs and VCD players have gradually faded from view due to technological advancements. Television has also evolved into smart terminals. Smart terminals are new products born from the impact of the internet wave, aiming to provide users with a more convenient experience and have become a mainstream trend in television. Smart terminals are fully open platforms with operating systems, allowing users to install and uninstall various applications while enjoying regular television content, continuously expanding and upgrading their functionality. Smart terminals offer users a richer, more personalized experience compared to using a cable digital television receiver (set-top box).

[0003] Existing karaoke entertainment systems include a TV, microphone, and remote control. The microphone only has an on / off switch, and the remote control is used to control the TV's audio output, including volume control and song selection (previous / next track). The TV receives the audio output from the microphone and outputs it through its built-in speakers. To allow users to conveniently and quickly select songs, a system has been developed that allows one-click voice song selection via the microphone on any interface of a smart device. This involves adding a one-click voice song selection button to existing wireless microphones, and using the microphone's built-in module to convert the button press into commands, which are then sent to the karaoke receiver module and backend service to activate the recording device. This enables the microphone to transmit voice song selection information to the smart device, providing users with a convenient and quick song selection function using a wireless microphone on their smart devices.

[0004] However, most existing karaoke entertainment systems are all-in-one designs with fixed and non-removable screens, which cannot meet the needs of outdoor portability and multi-scenario use at home; at the same time, the high latency of wireless audio transmission causes the vocals and accompaniment to be out of sync, affecting the user experience.
