Description

Technical Field

[0001] The present invention relates to the technical field of microphones, and in particular to a sound-activated luminous microphone. Background Art

[0002] A microphone is a common sensor that converts sound signals into electrical signals. It generally includes a mesh head, a handle, an acoustic-to-electrical conversion device, a signal transmission device, and a signal transmission switch. The mesh head is connected to the handle, which houses the acoustic-to-electrical conversion device. The handle houses the signal transmission device, and the handle houses the signal transmission switch. The acoustic-to-electrical conversion device is connected to the signal transmission device, which is then connected to the switch, which controls the transmission of sound signals. The signal transmission device can be either wired or wireless. With rising living standards, modern people are increasingly embracing leisure and entertainment after busy work. Singing is a popular leisure activity, leading to the rapid development of KTVs in recent years. However, when people sing and entertain themselves in KTVs or at home, the microphones they use are often limited to just singing, often leaving them feeling cold and unappealing.
