[0002] With the continuous advancement of science and technology, smart pen (dot pen) products have gradually been accepted by the market as an electronic product to assist writing. In the existing smart pen, when the pen tip is pressed down, the pressure sensor is triggered, and the built-in high-speed camera is started to take pictures of the dot matrix passed by the pen tip at a speed of 100 pictures per second, and the dot matrix coordinates, handwriting sequence, pressure data, movement speed and other information are transmitted to the built-in processor, and finally transmitted to the outside in real time through the Bluetooth or USB communication unit. However, the current smart pen needs to be connected to other smart devices to synchronize or read the written information, and the dot matrix pen itself cannot interact with the user; for this reason, there is a public technology that proposes a dot matrix pen, including a shell, the shell surrounds to form a accommodating space, and a camera module and an output module are arranged in the accommodating space, the output module includes a display screen and a speaker, the shell is provided with an opening matching the display screen, the display screen is exposed from the shell through the opening, and the shell is provided with a sound outlet corresponding to the speaker; a pen tip is provided at one end of the shell, the camera module is exposed from the end of the shell where the pen tip is provided, and takes pictures of the reading or writing information when the pen tip is reading or writing, and the output module outputs the information photographed by the camera module. The dot matrix pen provided by the improved technology, by setting a display screen and a speaker, enables the user to view the written information through the display screen and also read aloud through the speaker, through the dual interactive functions of vision and hearing;

[0003] However, in order to improve the battery life of smart pens, other existing technologies including the above-mentioned improved technologies, especially after adding new power consumption units, have higher requirements for battery life. Many manufacturers choose to extend and thicken the battery so that more electricity can be stored in one charge. The corresponding increase in battery volume will inevitably increase the weight of the pen body, seriously affecting the writing action, and needs further improvement. Utility Model Content
