Problems solved by technology
[0002] Now it is advocated that everything is connected to the Internet, and network technology has penetrated into every corner of our lives, while traditional pianos lack a bridge to connect to the network
Although the electric pianos currently on the market have a certain way to connect to the network, the electric piano is purely electroacoustic, so there is still a big gap between the feel and the fidelity of the sound quality compared with the traditional piano.
In addition, for pianos, there are currently no external strength scoring products. For the photoelectric sensor used in the piano detection strength products, when installing, the existing piano system must be disassembled, and the detection distance needs to be measured and screwed. It is relatively complicated and has certain structural damage to the piano, which is unacceptable to many users
If the sensor is placed outside, the detection environment is inconsistent, changeable, unstable, and easily interfered by sunlight, which will eventually lead to inaccurate or insufficient strength collection.
In addition, due to the complicated installation and connection, the detection of the pedal signal is often ignored, which leads to the incomplete collection and retention of the information of the user playing the piano

The invention provides a piano sound collecting and broadcasting device and a key calibration method. The device includes a testing rod arranged over piano keys and is inside provided with a plurality of key detecting units in communicational connection with each other. The piano keys are divided into multiple sections and each key detecting unit is corresponding to one section of the piano keys and is used for detecting displacement of the keys during a playing process and generating corresponding key sampling signals. By arranging the piano sound collecting and broadcasting device in a traditional piano, teaching can be realized and defects of electric pianos in the prior art can be made up.
