Description

Technical Field

[0001] The present invention relates to the technical field of capacitive pens, and particularly to an active capacitive pen with an AI intelligent voice module and a control method thereof. Background Art

[0002] An active capacitive pen is a high-precision input device that interacts with a touch screen through a built-in circuit. Compared with a passive capacitive pen (which only simulates finger touch), it has advantages such as pressure sensitivity, tilt detection, and low latency, and is widely used in fields such as drawing, note-taking, and design.

[0003] Existing active capacitive pens have the following limitations: single input method: only touch input is supported, and functions cannot be quickly called through voice; poor device compatibility: generally, a capacitive pen needs to manually switch system protocols to adapt to different systems. For example, users need to manually switch between the Android protocol system and the Apple protocol system, switch pen brushes, and manually select colors, etc., with low interaction efficiency. Therefore, an AI voice module needs to be loaded inside the capacitive pen to increase the convenience of the capacitive pen. The Android protocol system and the Apple protocol system can be switched through the voice system, solving the core pain points of traditional capacitive pens with single interaction and poor compatibility. Usually, the shapes of capacitive pens are divided into cylindrical, D-shaped, and other shapes. When using cylindrical and D-shaped capacitive pens, users will casually place the capacitive pen on the desktop, and the capacitive pen will roll under books and papers, and users still need to search for it. At the same time, in order to ensure the normal use of the microphone module on the capacitive pen, a dust-proof net is added on one side of the microphone module of the capacitive pen. However, after long-term use, the dust accumulated on the dust-proof net will affect the sound pickup and sound playback of the microphone module. Therefore, there is a lack of a mechanism for conveniently placing the capacitive pen and protecting the dust-proof net during the placement process. Summary of the Invention

[0004] To solve the above problems, the present invention provides an active capacitive pen with an AI intelligent voice module and a control method thereof to solve the problems of low interaction efficiency of the capacitive pen, easy rolling and the need for users to search, and the lack of protection for the dust-proof net.

The hollow rod rotates on the rotating rod and expands outward from the placement seat, and the moving rod moves inside the hollow rod. When the placement seat contacts one end of the capacitive pen body, the moving rod is perpendicular to the capacitive pen body and contacts the desktop. With the support of several rotating plates, the capacitive pen body can be stably placed on the desktop, facilitating subsequent use and retrieval by the user. At the same time, when not in use, one side of the placement seat contacts one end of the capacitive pen body, protecting the dustproof net and preventing dust from accumulating in the dustproof net, which affects the microphone group from transmitting commands to the AI main control chip for processing.

The active capacitive pen with an AI intelligent voice module according to claim 1, characterized in that, The flat placement protection mechanism (7) includes a rotating groove (701), a rotating plate (702), a rotating seat (703), a hollow rod (704), a moving rod (705) and a rotating rod (706). A plurality of rotating grooves (701) are provided. All of the plurality of rotating grooves (701) are formed on the outer side of the capacitive pen body (1), and the plurality of rotating grooves (701) are equidistantly arranged in a circular array along the outer wall of the capacitive pen body (1). The rotating plate (702) is rotatably connected inside the rotating groove (701). One end of the rotating plate (702) is rotatably connected to the rotating seat (703). A hollow rod (704) is arranged on one side of the rotating seat (703). A moving rod (705) is slidably connected inside the hollow rod (704). One end of the moving rod (705) is fixedly connected to one side of the rotating seat (703). A plurality of mounting grooves (9) are formed on the outer wall of the placement seat (8). The plurality of mounting grooves (9) are equidistantly arranged in a circular array. A rotating rod (706) is fixedly connected inside the mounting groove (9). One end of the hollow rod (704) is rotatably connected to the outer wall of the rotating rod (706).

10. A control method for an active capacitive pen with an AI intelligent voice module, characterized in that, Comprising the following steps: S1. Switch and power supply: When using the capacitive pen body (1), long-press the power key (501) to start or close. When the power key (501) controls the battery (504) to start, the capacitive pen body (1) is turned on. In cooperation with the charging port (502), a charging instruction can be given to the battery (504), and the charging condition of the battery (504) can be observed through the indicator light (503); S2. Sensing and Real-time Detection: When the conductive pen tip (201) contacts the place to be read, through the action of the infrared proximity sensor (202), the anti-mis-touch function can be realized according to the distance between the conductive pen tip (201) and the external screen. And through the six-axis gyroscope (204) and the pressure sensor (203), the holding posture of the user can be detected in real time, and the pen tip module (2) imports the instruction into the AI main control chip (3) for recognition and use; S3. Voice Mode: The user's instruction is transmitted to the AI main control chip (3) through the microphone group (601) for recognition, and then the voice instruction is exported through the speaker (605) by the AI main control chip (3) and transmitted to the user in the form of voice broadcast; S4. Pairing and Transmission: Through the action of the Bluetooth receiver (401) and the Wi-Fi Direct receiver (402), the multi-mode wireless protocol is adopted for pairing the device with the external terminal device, which is convenient for transmitting the user's handwriting and voice data to the external terminal for recording.
