Description
Technical Field
[0001] The present invention relates to the technical field of electric flutes, in particular to an intelligent electric flute and a control system thereof. Background Art
[0002] As a traditional Chinese folk instrument, the bamboo flute has a long history and unique artistic charm. However, the learning threshold of the traditional bamboo flute is high, and players need to practice for a long time to master the correct blowing techniques and pitch control. What is particularly critical is that the traditional bamboo flute itself lacks an interactive feedback mechanism. It is difficult for beginners to immediately know whether the performance effect is correct during practice. They are easily frustrated by slow progress or deviation from the direction, which leads to a decrease in learning interest. Although some existing electric wind instruments have achieved electronicization of musical instruments, their sound triggering method generally adopts a vertical blowing structure, which is significantly different from the horizontal blowing method of the traditional bamboo flute. This difference is not only inconsistent with the habits and cognition of traditional bamboo flute players, but also makes it difficult to attract bamboo flute enthusiasts and beginners who are accustomed to the horizontal blowing method. More importantly, such products generally fail to effectively solve the learning difficulties of beginners, the learning curve is still steep, and there are obvious deficiencies in reducing learning costs and providing effective guidance.
[0003] The traditional bamboo flute has a high learning threshold and lacks feedback: The traditional bamboo flute is difficult to learn and lacks a real-time feedback mechanism, which can easily cause beginners to lose interest and find it difficult to continue learning and master it in depth. The current electric blowpipe playing method does not conform to traditional habits: Existing flute-like electric blowpipe products generally use a vertical blowing method to produce sound, which is fundamentally different from the horizontal blowing method of the traditional bamboo flute. It does not conform to user cognition and habits, and is difficult to attract traditional bamboo flute enthusiasts and beginners. The complexity of traditional fingering leads to high learning costs: The traditional bamboo flute fingering system is complex, and users need to invest a lot of time practicing to master it, which significantly increases the learning cost and difficulty.
