In order to make those skilled in the art better understand the embodiment of the present disclosure, the following describes one specific example:
Specifically, referring to
Specifically, the gravity sensor can measure motion acceleration values in three dimensions, which are represented by digits of three dimensions x, y, z. When the musical instrument is stationary, although there is no movement, there is still a gravity acceleration in a vertical direction. Therefore, changes of the gravity accelerations in three directions can be measured in the stationary state. For example, when a printed circuit hoard (PCB) of the portable electronic musical instrument is vertical, x=z=0, and y=g. When the PCB of the portable electronic musical instrument and a vertical line form a degrees, x=g*sin a, y=g*cos a, and z=0. The values of x, y, and z can be read from the sensor, thus calculating corresponding angles a. That is, an angle represents a register. Different registers correspond to a certain angle range. For example, (−180, −45), (−45, −45), and (45, 180) are defined to be three registers, which are respectively a treble area, a mid area, and a bass area.
For example, a finger piano is held with the left hand, with the speaker upwards, and a benchmark area is the mid area. The bass area is rotated from the benchmark area from the right to a certain angle, and the treble area is rotated from the benchmark area from the left to a certain angle. In the same way, the finger piano is held with the right hand, with the speaker upwards. The benchmark area is the mid area. The bass area is rotated from the benchmark area to the right. The treble area is rotated from the benchmark area to the left. The user can hold the portable electronic musical instrument, and dance while playing corresponding music. The portable electronic musical instrument has a light weight and a small volume, and is very suitable for the performance in the form of singing and dancing joyously.
