The manufacturing principle of the orientable laser pointer
In today's multimedia classrooms, computers, projectors, electronic whiteboards, etc. are widely used in presentation activities such as lectures and teaching. Rich voices, texts, images, videos, animations, etc. can be displayed in front of students and audiences in many ways. The lecturer needs to use multiple devices such as Laser pointer and mice to control the explanation software and works running in the computer to assist in classroom teaching.
In teaching or demonstration, the traditional mouse is used only, the speaker is restricted to the computer, and cannot approach the audience. When interacting with the audience and requiring mouse operation, they have to return to the computer, which delays the explanation time and affects the explanation. Quality, and the use of a wireless mouse requires a flat surface, which is inconvenient to use. In addition, the laser pointer has a color pointing and marking function that the traditional mouse does not have. Some words on the above are pointed to to guide the audience to follow the explainer’s thoughts.

The directional laser pointer includes a protective casing and a controller module arranged inside the protective casing. A signal conversion module is also arranged inside the protective casing, and a first infrared emitting device and a first infrared receiver are arranged at one end of the protective casing. A device and a laser emitting device, wherein the first infrared emitting device and the first infrared receiving device are both connected to the controller module through a signal conversion module, and the laser emitting device is directly connected to the controller module; and, on the external object to be pointed A second infrared receiving device and a second infrared emitting device are provided, and the second infrared receiving device is electrically connected to the second infrared emitting device through a controller. The directional laser pointer provided by the utility model can solve the problem that the laser irradiates others due to misoperation by the operator.
