Laser string with interaction effect

Abstract

The invention discloses a laser string with an interaction effect. The laser string comprises a mounting base and two calibration mechanisms, wherein an outer wall of the mounting base is symmetrically provided with arc-shaped mounting grooves, inner cavities of the two arc-shaped mounting grooves are both provided with U-shaped mounting rings, two calibration mechanisms are symmetrically arranged on the two sides of the mounting base, each calibration mechanism comprises a threaded hole, a telescopic hole is formed in one side of the inner wall of the threaded hole, a calibration hole is formed in one side of the U-shaped mounting ring, an inner cavity of the threaded hole is in threaded connection with a threaded rod, and one end of the threaded rod is rotationally connected with a calibration rod. Through the arrangement of the threaded hole, the threaded rod, the telescopic hole, the calibration hole and the calibration rod, the threaded rod in the threaded hole is rotated, so the calibration rod is driven to move in the telescopic hole and be inserted into the calibration hole, the alignment work of the two U-shaped mounting rings is completed, and meanwhile, the work that a laser emits light beams to be aligned with a photoelectric receiver is completed; and precision of laser string installation is improved.

Description

technical field [0001] The invention relates to the technical field of laser strings, in particular to a laser string with interactive effects. Background technique [0002] Laser piano is a laser piano with laser beams as strings. Through constant light control, different scales and melodies can be played. According to the structure of the beam forward direction, the laser outputs the total beam in turn, and the split beam is separated out as the strings by the light splitting element. The photoelectric receiver converts the optical signal into an electrical signal and sends it to the electronic controller connected to the keyboard. The laser beam strings can be seen but cannot be touched by human eyes. When placed in the playground, the strings with colored light will shine, and at the same time, they can emit beautiful piano sounds. The laser piano made by laser technology and optical control principle allows the player to play without touching the piano body with his h...

Problems solved by technology

[0003] During the installation process of the laser strings, it is necessary to ensure that the beam emitted by the laser is aligned with the receiving points on the photoelectric receiver. However, in the actual installation process, since the installation personnel only observe and calibrate with the naked eye, there will be a gap emitted by the laser. There is a deviation between the light beam and the photoelectric receiver. This phenomenon requires the staff to re-install the work or make fine adjustments, which is a waste of time and also reflects the poor accuracy of laser string installation.
