On the other hand, the optical signal sent from the external device is processed by the optical detection diode and the amplifier inside the optical receiving module, so as to output an electrical signal with a corresponding code rate, and the electrical signal is transmitted to the control and processing unit. The musical instrument bullet following system and the external equipment carry out data transmission through the optical signals, so that the defect of large attenuation of electric signal transmission can be effectively overcome, the data transmission speed is higher, the anti-interference capability is stronger, and the performance of the musical instrument bullet following system is improved.

In another embodiment, the wireless transmission interface may be one or more of a bluetooth interface, an infrared interface, a WIFI interface, and the like, for example, as needed. The wireless transmission interface is connected with the control and processing unit in a wireless mode, and therefore data transmission between the musical instrument bullet following system and the external equipment is achieved. In one embodiment, the wireless transmission interface may be, for example, a bluetooth interface including a bluetooth module. The Bluetooth interface can be used for connecting the musical instrument bullet following system and the external loudspeaker, wherein the Bluetooth module can be arranged in the musical instrument bullet following system and the loudspeaker, so that the position of the external loudspeaker can be conveniently and flexibly placed according to the requirement of field playing.

Further, the external speaker can be used for broadcasting actions of a player during playing or broadcasting sound for correcting the player playing. The loudspeaker can comprise a magnet, a frame, a centering support sheet, a vibrating mould folded ring cone-shaped cone and the like. Alternatively, the speaker may further include a power amplifier. A loudspeaker, commonly known as a "horn", is a transducer device that converts an electrical signal into an acoustic signal. During the operation of the loudspeaker, the audio electrical signal causes the cone or diaphragm of the loudspeaker to vibrate and resonate (resonate) with the surrounding air to produce sound through electromagnetic, piezoelectric or electrostatic effects. The operation of the musical instrument heel-pop system of the present invention will be briefly described with reference to fig. 1 and 2, taking a piano as an example.

First, an external device (e.g., a mobile phone) plays a piano score file that a player wants to learn to play. And then, the controller receives the corresponding note of the piano music score file through the Bluetooth interface and controls to light up the indicator lamp corresponding to the corresponding note on the piano keyboard. Then, the player presses the key corresponding to the note in accordance with the indication of the indicator lamp. Further, the sensor receives the above-described key depression motion, and transmits the key depression state information to the controller.

The controller then analyzes and processes the received information. Specifically, the controller obtains the corresponding note of the pressed key by inquiring the corresponding relation between the key and the note of the piano music score file, compares the note with the current pointed note in the piano music score file, and indicates that the player operates correctly if the note of the currently pressed key is consistent with the note corresponding to the currently played piano music score file. In view of this, the controller outputs a control signal of the indicator lamp corresponding to the next note so as to continue to guide the player to play. In contrast, if the controller detects that the note of the currently depressed key is not identical to the note corresponding to the currently played piano score file, it indicates that the player has an operation error. In this case, the controller again controls to light the indicator lamp corresponding to the current note on the piano keyboard to instruct the player to depress the correct key.

In the process, the operation reminding can be carried out on the player in a voice broadcasting mode. For example, when the player presses the wrong key, the present invention can play a sound for "wrong" warning through the speaker to remind him to correct the playing operation. Further, when the key needs to be pressed for a long time, the controller can control the indicator lamp corresponding to the key to show different colors. For example, when the indicator lamp appears green, the player is reminded of the need to press the key for a long time. In addition, when the key needs to be pressed with a larger degree of pressure, the controller can control the indicator lamp corresponding to the key to show another color, for example, when the indicator lamp shows red, the player is reminded that the key needs to be pressed with force. In addition, other indicator lamp colors can be set to prompt the player of specific time for pressing the keys.
