receiving a third signal output by the attitude sensor,

and determining a sound zone corresponding to the third signal according to the third signal.

This step is used to determine the range before the performance is started, for example, the simulated piano is divided into a bass range, a midrange range and a treble range, the gesture sensor is connected to the touch screen, the motion state of the touch screen can be detected, and the different ranges are determined by analyzing the motion state of the gesture sensor. In one embodiment, different sound zones are determined by detecting angular movement data of the gesture sensor, and a user can hold the touch screen for operation and use the elbow joint as an axis, and after the touch screen rotates by a certain angle in the horizontal direction (the angle is measured by the gesture sensor), the sound zone where the touch screen is located is determined, for example, after the touch screen rotates by every 15 degrees by using the elbow joint as the center in the horizontal direction, the user needs to determine the sound zone in the range of 45 degrees before playing starts, and when a key zone on the touch screen is touched, a pitch corresponding to the key zone in the sound zone can be emitted.

calculating the duration t1 of the pressed area on the touch screen,

judging whether the time t1 is greater than a preset time threshold t 0;

when t1 is greater than t0, the generated tone is caused to be played for a prolonged period.

The above steps are used for simulating a long tone when the intelligent musical instrument simulates some musical instruments (such as a piano, an electronic organ or a wind-string musical instrument, for example, a flute, etc.), and after detecting that the duration of the touch key of the user exceeds a preset threshold, for example, the threshold is set to 500ms, the corresponding musical tone is continuously played, and conversely, after the user clicks the touch screen, the finger rapidly leaves the touch key area, and the corresponding musical tone is instantly generated. The method more truly simulates the traditional musical instrument.
