Description

Technical Field

[0001] The invention relates to music playing technology, in particular to a new type of music equipment with multi-functions and multi-channels for inputting audio signals. Background Art

[0002] MIDI technology, MIDI is the acronym for Musical Instrument Digital Interface, which can be translated into "electronic musical instrument digital interface". The sound of electronic musical instruments can be directly played through speakers through the MIDI interface, and the speakers that play the sound of electronic musical instruments are speakers with MIDI interfaces. Such speakers are widely carried by street artists for outdoor performances.

[0003] DSP chip technology, DSP is Digital Signal Processing, that is, digital signal processing technology, DSP chip refers to the chip that can implement digital signal processing technology. The DSP chip adopts the Harvard structure with separate program and data, has a special hardware multiplier, widely uses pipeline operation, and provides special DSP instructions, which can be used to quickly implement various digital signal processing algorithms.

[0004] Electroacoustic musical instrument technology refers to the fact that electric musical instruments are electric mechanical devices with active structures, while electronic musical instruments are completely composed of circuits. For example, the electric piano generates mechanical waves by striking a tuned metal rod, which are then converted into electrical signals; the electronic piano has no other moving parts except the keyboard and control buttons, and its sound is generated by circuits, not by striking metal rods. The electric piano is similar to the traditional piano in appearance and the process of producing sound, but its sound is very different from that of the traditional piano; the electronic piano only retains a keyboard similar to that of the traditional piano, and its process of producing sound is very different from that of the traditional piano, but it can produce sounds similar to those of the traditional piano.

[0005] When using musical instruments for performance, performers often need to use microphones, MIDI interfaces or external speakers and other sound enhancement and adjustment equipment to optimize the performance effect. However, since most performers lack professional knowledge about MIDI operation, microphone debugging and tuning technology, they often find it difficult to make full use of these advanced equipment on the stage, thus limiting the flexibility and expressiveness of the performance. In the existing solutions centered on the mixing console, various cables are needed to connect instruments with different music information formats, resulting in the need for a large number of connecting cables and adapters, which increases the difficulty of use and the versatility of the equipment.
