The elevator music is set on the controller in the car, and the music settings need to be completed through a computer.

Elevator refers to a permanent transportation equipment that serves several specific floors in a building and whose cars run on at least two rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° with the plumb line. There are also step-type escalators, where the treads are mounted on caterpillar tracks and run continuously, commonly known as escalators or moving walkways. Fixed lifting equipment serving specified floors. A vertical lift elevator has a car that runs between at least two rows of vertical or rigid guide rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or to load and unload cargo. It is customary to use elevators as a general term for vertical transportation within a building regardless of their driving method. According to speed, it can be divided into low-speed elevators (below 4 meters/second), fast elevators 4 to 12 meters/second) and high-speed elevators (above 12 meters/second). Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings. In 1852, E.G. Otis of the United States developed a safety elevator for wire rope lifting. In the 1980s, the driving device was further improved, such as the motor driving the winding drum through a worm drive and the use of counterweights. At the end of the 19th century, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator.

Elevators at the end of the 20th century used permanent magnet synchronous traction machines as power. It greatly reduces the area occupied by the computer room, and has the advantages of low energy consumption, energy saving and high efficiency, and fast improvement speed, which greatly promotes the development of real estate in the direction of super high-rise buildings.
