The intelligent karaoke terminal, also known as the karaoke microphone Or K song treasure, it is a microphone with its own speaker, which is convenient for users to perform k song without speakers to meet the user's entertainment needs.

Existing general smart karaoke terminals all have a sound reinforcement system consisting of pickups, power amplifiers, and speakers. As long as it is a sound reinforcement system, there must be an acoustic feedback phenomenon. The acoustic feedback phenomenon is caused by part of the sound energy returning to the pickup through the reflection of objects such as human body and walls. Under normal circumstances, if the reflected sound re-enters the sound reinforcement system and forms positive feedback, and this phenomenon continues, the output signal volume will continue to increase, resulting in howling. Violent whistling can also make listeners feel extremely unpleasant. However, the existing smart karaoke terminals on the market generally have mounting holes on the top of the sound cavity body for installing the pickup components. Since the sound cavity body mainly plays the role of sound amplification, the sound generated by the speaker is easily reflected from the sound cavity.
