As shown in fig. 3, the sound synthesis interactive module includes a sound synthesis unit 301, a sound receiving unit 302, a display unit 303, a broadband electronic sound emitting unit 304, and an interactive processing unit 305. The sound synthesis unit 301 synthesizes the electrical signals of the required tone, range and timbre according to the keys of the soft definition keyboard, and outputs the electrical signals through the broadband electronic sound production unit 304. The frequency domain range of the electric signal is a sound wave frequency band (namely, the frequency band of the hearing range of human ears is 20Hz-20 KHz) and an ultrasonic frequency band (namely, more than 20 KHz). The sound wave band is used for playing and interacting functions, the ultrasonic wave band is used for interacting functions, and the sound wave band is specifically determined according to the requirements of a use scene, for example: in small-scale multi-person ensemble scenes such as small class teaching, parent-child activities and the like, the multi-person ensemble scene can be arranged in a sound wave frequency band, and a frequency modulation signal with special tone can be adopted, so that the identification degree is improved, and the real-time interactive feedback is facilitated; on a large scale such as big class teaching, stage table performance, the multi-instrument performance scene can be set at the ultrasonic frequency range, and multi-person communication interaction is realized while other players and audiences are not influenced.
The sound receiving unit 302 is used for receiving sound wave band/ultrasonic band signals from other musical instruments and transmitting the signals to the interactive processing unit 305.

The interactive processing unit 305, according to the sound wave band/ultrasonic band signals received by the sound receiving unit 302 from other musical instruments, may demodulate the sound wave band/ultrasonic band interactive signals sent by other musical instruments, and may make various comparisons with the sound signals sent by itself, for example: self-correlation and the like, and automatically analyzes the playing state according to the music score to prompt the player that the rhythm is faster or slower, and the like.
The digital keyboard type musical instrument with the sound interaction function can realize interaction among the same types and can also interact with a traditional musical instrument without modification. An embodiment of acoustic interaction may take the following form:
1) between said instruments of the invention: the acoustic synthesis interaction module sends an interaction instruction to the outside to realize the coordination communication among the musical instruments; meanwhile, the sound synthesis interaction module automatically analyzes and prompts the playing state and prompts the player. The interactive instruction at this time can adopt a sound wave frequency band/an ultrasonic frequency band.
2) The invention interacts with the instrument without modifying the traditional instrument: the two musical instrument players agree on the form of interactive instructions, and the interactive instructions need to adopt a sound wave frequency band. A. The musical instrument can be used as a command role, can transmit modulated rich acoustic signals to coordinate the playing speed, and a traditional musical instrument player hears interactive instructions to make proper adjustment. B. If a traditional musical instrument player is used as a command role and can play sound signals of timbre and range which are predetermined before as interactive command signals, the sound synthesis interactive module of the musical instrument analyzes the received sound signals into interactive commands and displays and prompts the received sound signals to the player. Of course, the musical instrument player can directly distinguish the interactive instructions of the sound wave frequency band when the music literacy is high enough.
The above-mentioned sound synthesis interaction module can also be separated out as a supplementary accessory of the traditional musical instrument, and is used for interaction between the traditional musical instruments. A conventional musical instrument equipped with a sound synthesis interaction module as a supplementary accessory, which has the same interaction function as the musical instrument of the invention, and therefore, the embodiment of the sound interaction between them, and between them and the musical instrument of the invention can refer to the mode 1).
