Technical Field

[0001] The utility model relates to the field of entertainment equipment, and in particular to a Bluetooth speaker with omnidirectional screen projection, projection and text functions. Background Art

[0002] A speaker is a device that can convert audio signals into sound. In layman's terms, it means that the speaker main box or subwoofer box has a built-in power amplifier, which amplifies the audio signal and then plays it back through the speaker itself, making the sound louder.

[0003] At present, when using existing karaoke speakers for a series of entertainment such as singing, people often connect the speakers to the speakers through the Bluetooth of mobile phones, and then sing. However, the Bluetooth connection of mobile phones to speakers only has a simple audio output function, that is, the speakers can only realize singing, and the singer still needs to sing through the lyrics on the mobile phone screen. However, the mobile phone screen and subtitles are too small, which makes it inconvenient for the singer to see the lyrics, which brings great inconvenience to the users. The applicability is poor and cannot meet the actual use requirements.

[0004] Therefore, it is necessary to provide a Bluetooth speaker with all-round screen projection, projection and text functions to solve the above problems. Utility Model Content
