Description

Technical Field

[0001] This invention relates to the field of intelligent educational equipment technology, specifically to a handheld learning terminal designed for memorization scenarios, featuring offline intelligent processing and authorized network connectivity. Background Technology

[0002] Currently, in educational settings, students rely heavily on smartphones, tablets, and other general electronic devices for memorizing texts, key points, and foreign language vocabulary. These devices are often cluttered with entertainment features, easily distracting students and diverting their attention. While some dedicated learning devices are focused on the learning environment, they largely depend on cloud networks for intelligent processing, failing to function properly offline and lacking control over internet access, leading to uncontrolled internet use. Furthermore, existing devices often feature large, fully touch-screen designs, lacking portability and specific operational features, failing to meet students' needs for efficient and focused memorization. Therefore, developing a dedicated, offline-usable, and network-controllable intelligent memorization learning device has become a pressing technical challenge in the field of educational smart hardware. Summary of the Invention

[0003] To address the technical shortcomings of existing general-purpose learning devices, such as easy distraction, lack of offline intelligent processing capabilities, and lack of control over network access, this invention provides an intelligent memorization learning terminal. It achieves offline core function operation through an independent edge intelligent processing unit, manages network usage through a dual-authorization network mechanism, and combines a dedicated handheld configuration design to improve the focus and efficiency of memorization learning.

[0004] The technical solution of this invention is as follows: an intelligent memorization learning terminal, comprising a main control processing unit, a local data storage unit, a touch display unit, a voice acquisition and playback unit, an authorized network unit, a power supply unit, and an edge intelligent processing unit; the local data storage unit is used to pre-store various memorization text materials and voice template data, which can be retrieved without network access; the touch display unit is used to display memorization content, learning progress, and operation interface; the voice acquisition and playback unit can acquire the user's memorization voice in real time, and simultaneously play standard reading audio and learning prompts; the edge intelligent processing unit completes voice recognition, text comparison, pronunciation correction, and memorization scoring locally, without requiring network data transmission throughout the process; the authorized network unit only grants temporary network access after remote or near-field authorization, and automatically disconnects the network after data synchronization is completed; the power supply unit provides a stable power supply to the entire module, ensuring long-term offline operation of the terminal.

[0005] Furthermore, the terminal adopts a straight rectangular handheld structure with R1.5 rounded corners to avoid sharp edges and improve handheld comfort. The front features an 8-inch display panel with four equidistant circular physical buttons below, corresponding to functions such as memorization activation, content switching, voice recording, and progress query, making operation simple and easy to understand.

[0006] Furthermore, the back of the terminal features a linear array of elongated sound holes to ensure clear audio playback without noise interference, thus meeting the voice interaction needs for memorization and learning.

[0007] Furthermore, the authorized network unit adopts a dual authentication mechanism: remote authorization is achieved through cloud account verification, and near-field authorization is achieved through Bluetooth pairing with the control device. The two methods can be used independently to meet the temporary network needs in different scenarios. After the network connection ends, the network connection is automatically shut down to prevent unauthorized internet access.

[0008] The beneficial effects of this invention are as follows: It adopts a dedicated handheld design, eliminates redundant entertainment functions, focuses on the memorization and learning scenario, and effectively improves students' concentration; it is equipped with an edge intelligent processing unit to achieve fully offline intelligent voice recognition and error correction, and can use the core functions normally even in the absence of a network environment; the dual-authorization network mechanism enables controllable network use, avoids unrestrained internet access, and takes into account both the synchronization of learning materials and the security of use; the overall structure is simple and portable, easy to operate, and suitable for students' daily memorization and learning in various scenarios both inside and outside of school.

Detailed Implementation

[0011] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0012] like Figure 1 , Figure 2 As shown, the intelligent memorization learning terminal of the present invention has a straight rectangular structure with R1.5 rounded corners. An 8-inch touch display panel is installed in the center of the top of the front. Four circular physical buttons are evenly spaced below the panel. The buttons are of the same size and have a uniform layout, which is convenient for one-handed operation. A linear strip-shaped speaker hole array is opened in the center of the back of the terminal. The opening size of the sound holes is uniform and corresponds precisely to the internal voice playback components.

[0013] like Figure 3 As shown, the terminal uses the main control processing unit as the core control module. The local data storage unit and the edge intelligent processing unit are bidirectionally connected to the main control processing unit. The local data storage unit imports various memorization texts and audio materials in advance, while the edge intelligent processing unit independently completes voice acquisition, text comparison, and pronunciation correction without relying on the external cloud network. The touch display unit and the voice acquisition and playback unit respectively realize the interface display and voice interaction functions. The authorized network unit is controlled by the main control processing unit and only opens the network connection after authorization is passed and disconnects immediately after data synchronization is completed. The power supply unit uses a rechargeable lithium battery to provide continuous power to all modules.

[0014] like Figure 4 As shown, the terminal workflow is as follows: First, the terminal is started to complete system initialization, load locally stored memorization materials and system parameters, and directly enters offline learning mode after initialization. Users can rely on local materials to carry out memorization learning and complete recording and self-assessment through the voice acquisition and playback unit. When it is necessary to connect to the network to synchronize materials or update content, an internet access request is initiated, and the system automatically jumps to the authorization verification stage. Users can choose between remote cloud authorization or near-field Bluetooth authorization. After successful verification, the system proceeds to the authorization result query step. After confirming successful authorization, the terminal starts temporary network mode to execute network data interaction tasks. After the task is completed, the system automatically triggers a network disconnection command and returns to offline learning state. No manual intervention is required to switch the network on and off throughout the process.

[0015] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, or improvements made to the embodiments based on the technical principles of the present invention are included within the protection scope of the present invention.
