Description

Technical Field

[0001] This invention relates to the field of recording equipment technology, and in particular to a recording device and its storage method, program product, medium and computer system. Background Technology

[0002] A recording device is a portable recording device that integrates artificial intelligence voice processing algorithms. For example, existing recording cards. After recording, the recording card transmits the recording to a mobile phone. The mobile phone then connects to the cloud to analyze the recording, performs text recognition, and then transmits the recognized text back to the mobile phone for the user to view.

[0003] Recording devices typically use eMMC (embedded multimedia card) for storing recordings. EMMCs are usually configured as a single storage space without physical or logical partitioning. However, recordings generally occupy relatively little storage, resulting in significant underutilization of the recording device's storage space. Existing eMMCs lack extended reuse capabilities, and common storage reuse schemes are prone to conflicts with recording functions, exhibiting poor compatibility. Furthermore, eMMCs only serve as passive storage media for recording data, without establishing a secure data exchange mechanism with external devices. One solution to simultaneously achieve recording and data storage functions is to use multiple external eMMCs. However, this approach leads to insufficient eMMC interfaces on the SoC. Even if there are enough interfaces, external solutions can cause high power consumption in the recording device, negatively impacting its long battery life and portability. Summary of the Invention

[0004] To address the problem of low storage space utilization and severe underutilization of storage space in existing recording devices, this invention provides a recording device and its storage method, program product, medium, and computer system.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a recording device, comprising a main control module and a storage module, a recording module, and a dual communication module electrically connected to the main control module; the storage module has a first storage partition and a second storage partition signal-connected to the main control module, the first storage partition and the second storage partition being independent of each other; the dual communication module includes a wired connection module, a wireless connection module, and a verification module; the main control module is signal-connected to the wired connection module, the wireless connection module, and the verification module respectively; the output terminal of the recording module is connected to the main control module, the main control module receives recording information from the recording module, processes the recording information into audio information, and stores the audio information in the first storage partition; the output terminals of the wired connection module and the wireless connection module are respectively connected to the main control module, the main control module receives external data storage information from the wired connection module or the wireless connection module, and controls the verification module to perform verification; after successful verification, the main control module stores the external data storage information in the second storage partition. When an external device initiates a connection via wired or wireless means, the main control module verifies the connection through the authentication module. Only after successful verification is access to the second storage partition granted. Existing recording products do not reuse the eMMC (emulated media player); the eMMC is only used to store recording information and does not provide extended storage functionality for external data. In this embodiment, the first and second storage partitions are independent. The main control module has control and scheduling capabilities to control the conversion of received recording data into audio information stored in the first partition, or the storage of received external data information in the second partition. The recording devices do not interfere with each other during recording and / or data storage, thus preventing stuttering or data loss during these processes. Furthermore, the unified scheduling by the main control module ensures the orderly execution of both recording and extended storage functions, avoiding idle storage space resources in existing recording devices.

[0006] Preferably, the verification module includes a first verification module and a second verification module. The main control module includes a connection terminal, a first information input terminal, a second information input terminal, a third information input terminal, a first information output terminal, a second information output terminal, and a third information output terminal. The connection terminal is connected to the first verification module and the second verification module respectively. The output terminal of the recording module is connected to the first information input terminal of the main control module, and the first information output terminal is connected to the first storage partition. The main control module receives recording information from the recording module, converts the recording information into audio information, and stores the audio information in the first storage partition. The output terminal of the wired connection module is connected to the first information input terminal of the main control module. The second information input terminal is connected, and the second information output terminal is connected to the second storage partition. The main control module receives external data storage information from the wired connection module and controls the first verification module to perform verification. After successful verification, the main control module stores the external data storage information in the second storage partition. The output terminal of the wireless connection module is connected to the third information input terminal of the main control module, and the third information input terminal is connected to the second storage partition. The main control module receives external data storage information from the wireless connection module and controls the second verification module to perform verification. After successful verification, the main control module stores the external data storage information in the second storage partition. The complete separation of the external data storage information and the recording information path ensures that data transmitted from external devices to the recording device cannot interfere with the audio information stored in the recording device.

[0007] Preferably, when the main control module does not receive recording information from the recording module and external data storage information from the wired connection module or the wireless connection module at the same time; the main control module is used to convert the recording information into audio information separately and store the audio information in the first storage partition, or, the main control module stores the external data storage information separately in the second storage partition. When the main control module receives recording information from the recording module and external data storage information from the wired connection module or the wireless connection module at the same time; the main control module is used to convert the recording information into audio information simultaneously and store the audio information in the first storage partition and store the external data storage information in the second storage partition.

[0008] Preferably, the recording module includes at least one airborne acoustic microphone and a bone conduction microphone, which are respectively connected to the first information input terminal of the main control module. Both the airborne acoustic microphone and the bone conduction microphone are used to collect external sounds and acquire recording information. The recording device also includes a power module and an interaction module. The power module is electrically connected to both the wired connection module and the main control module. The interaction module includes a display screen, an indicator light module, and a vibration motor module, which are electrically connected to the main control module. The power module provides power support, and the interaction module provides the user interaction experience.

[0009] To address the aforementioned technical problems, this invention provides another technical solution as follows: a recording device storage method for recording and storing data from an electronic device, comprising the following steps: providing a recording device, activating the recording device to enter standby mode, acquiring external recording information and / or external data storage information of the electronic device; if the recording device acquires recording information, processing the recording information to obtain an audio signal, and storing the processed audio signal in a first storage partition of a storage module; if the recording device acquires external data storage information, performing verification processing based on the external data storage information; if verification fails, the recording device returns to standby mode; if verification succeeds, the external data storage information is stored in a second storage partition of the storage module. Storing recording information and external data storage information in different storage partitions increases the security of the recording information while avoiding idle storage space resources in existing recording devices.

[0010] Preferably, activating the recording device to enter standby mode further includes: when the recording device enters standby mode, verifying the first and second storage partitions to obtain their storage information, generating a storage status based on the storage information, and sending the storage status to the electronic device; after sending the storage status, returning to standby mode. Users can grasp the storage status without guessing or performing tedious manual queries. The specific file transfer verification mechanism is as follows: in scenarios where files are transferred from the mobile phone to the device, the mobile phone first calculates the hash value (e.g., MD5) of the file to be transferred and temporarily stores this value; after the file is transferred to the device, the device recalculates the hash value of the received file and sends it back to the mobile phone; the mobile phone compares the hash values ​​calculated by both ends, and if they match, the file transfer is considered complete and error-free. Conversely, when files are transferred from the device to the mobile phone, the device first calculates the hash value of the file and sends it to the mobile phone; after the file transfer is complete, the mobile phone calculates the hash value of the received file and verifies it with the hash value sent by the device; if they match, the transfer is confirmed to be successful. The verification methods described above are not limited to the MD5 algorithm; other integrity verification methods such as SHA series hash algorithms, checksums, or error-correcting codes can also be used. Furthermore, the verification and comparison operation can be performed on either the mobile device or the terminal device, and the specific implementation method can be flexibly determined according to the system design.

[0011] Preferably, the process of processing the recording information to obtain an audio signal includes: sequentially performing signal fusion, noise reduction optimization, and encoding on the recording information to convert the recording information into an audio signal. Specifically, encoding to convert the recording information into an audio signal involves compressing the encoding and converting the audio signal into a compressed audio encoded file, which greatly reduces the storage size of the recording information.

[0012] Preferably, the external data storage information is acquired via a wired or wireless connection between the recording device and the electronic device. The verification process based on the external data storage information includes: determining the acquisition method of the external data storage information; if the external data storage information is acquired via a wired connection, the recording device sends a verification command to the electronic device via the wired connection, receives the verification result returned by the electronic device, and if the verification fails, the recording device returns to standby mode; if the verification succeeds, the external data storage information is stored in the second storage partition of the storage module; if the external data storage information is acquired via a wireless connection, the recording device displays the verification command, receives the verification result returned by the electronic device, and if the verification fails, the recording device returns to standby mode; if the verification succeeds, the external data storage information is stored in the second storage partition of the storage module. This added verification process enhances the security of the transmission process.

[0013] Preferably, activating the recording device to enter standby mode further includes: if the recording device and the electronic device simultaneously establish a wired or wireless connection, then the connection between the recording device and the electronic device is determined to be a wired connection. In abnormal or boundary states where dual communication links coexist, the recording device prioritizes the wired connection, as wired connections typically provide a more stable, lower latency, higher bandwidth, and less susceptibility to environmental interference.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] In the embodiments provided by this invention, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0028] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Those skilled in the art should also recognize that the embodiments described in the specification are optional embodiments, and the actions and modules involved are not necessarily essential to the invention.

[0029] In various embodiments of the present invention, it should be understood that the sequence number of each process does not necessarily imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0030] The flowcharts and block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of this application. In this regard, each block in a flowchart or block diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions indicated in the blocks may occur in a different order than those indicated in the drawings. For example, two consecutively indicated blocks may actually be executed substantially in parallel, or they may sometimes be executed in reverse order, depending on the functions involved. It is particularly important to note that each block in a block diagram and / or flowchart, and combinations of blocks in block diagrams and / or flowcharts, can be implemented using a dedicated hardware-based system that performs the specified function or operation, or using a combination of dedicated hardware and computer instructions.

[0031] Recording devices typically use eMMC (embedded multimedia card) for storing recordings. EMMCs are usually configured as a single storage space without physical or logical partitioning. However, recordings generally occupy relatively little storage, resulting in significant underutilization of the recording device's storage space. Existing eMMCs lack extended reuse capabilities, and common storage reuse schemes are prone to conflicts with recording functions, exhibiting poor compatibility. Furthermore, eMMCs only serve as passive storage media for recording data, without establishing a secure data exchange mechanism with external devices. One solution to simultaneously achieve recording and data storage functions is to use multiple external eMMCs. However, this approach leads to insufficient eMMC interfaces on the SoC. Even if there are enough interfaces, external solutions can cause high power consumption in the recording device, negatively impacting its long battery life and portability.

[0032] EMMC (Embedded MultiMediaCard) is a highly integrated embedded storage solution that encapsulates flash memory chips and flash memory controllers and connects to the host processor through a standardized interface. It provides unified storage management and read / write scheduling functions and is commonly used in mobile devices, embedded systems, and other applications with strict space and power consumption requirements.

[0033] SDNand (also known as surface mount SD card or eSD) is a storage medium that uses NAND flash memory and is packaged as a surface mount chip. Its electrical protocol is compatible with SD cards, but it is directly soldered onto the PCB in BGA or LGA form. This structure has better mechanical stability and shock resistance, and is suitable for embedded applications where high reliability is required and replacement is not easy.

[0034] A pogo pin (or spring probe) is an electrical connection component based on a spring structure. It achieves axial extension and retraction through an internal spring, and forms electrical contact with a mating terminal when compressed. It is commonly used in charging, data transmission, or testing interfaces in compact devices.

[0035] SoC (System on Chip) is an integrated circuit design paradigm that integrates a complete system component, such as a microprocessor, memory, peripheral interfaces, and digital and analog functional modules, onto a single chip. Through high integration, it achieves miniaturization, low power consumption, and high system performance, and is widely used in mobile communications, the Internet of Things, embedded control systems, and portable electronic devices.

[0036] Please see Figure 1 The first embodiment of the present invention provides a recording device 10, which includes a main control module 1, a storage module 2, a recording module 3, and a dual communication module 4 electrically connected to the main control module 1. The storage module 2 has a first storage partition 21 and a second storage partition 22 that are signal-connected to the main control module 1. The dual communication module 4 includes a wired connection module 41, a wireless connection module 42, and a verification module 43. The main control module 1 is signal-connected to the wired connection module 41, the wireless connection module 42, and the verification module 43, respectively. The output terminal of the recording module 3 is connected to the main control module 1. The main control module 1 receives recording information from the recording module 3, processes the recording information into audio information, and stores the audio information in the first storage partition 21. The output terminals of the wired connection module 41 and the wireless connection module 42 are respectively connected to the main control module 1. The main control module 1 receives external data storage information from the wired connection module 41 or the wireless connection module 42 and controls the verification module 43 to perform verification. After successful verification, the main control module 1 stores the external data storage information in the second storage partition 22.

[0037] It should be understood that in this embodiment, within a single recording device 10, the storage module 2 is divided into a first storage partition 21 and a second storage partition 22. It should be noted that, for example, if the main control module uses a Hengxuan 2800HP main control chip, this embodiment uses only one storage module 2, which is a storage medium. For example, the storage module 2 can be an embedded multimedia card (EMMC), i.e., a highly integrated miniature solid-state drive. This embodiment can select a storage medium with the largest possible capacity and then partition the large-capacity storage medium, which controls costs and solves the problem of excessive power consumption caused by multiple external storage media. Optionally, the storage medium can be EMC, SDNand, or an SD card; commonly used embedded device storage media can be selected, without further elaboration. The first storage partition 21 and the second storage partition 22 are independent of each other. The first storage partition 21 is dedicated to storing the recording information collected and processed by the recording module 3, ensuring the data independence of the core recording function. The second storage partition 22 is configured as extended storage space for receiving and storing data from external electronic devices such as smartphones. The independent partitioning design of the first storage partition 21 and the second storage partition 22 allows recording and data expansion to coexist at the physical storage level without interference. The dual communication module 4 integrates a wired connection module 41 and a wireless connection module 42, providing two optional transmission paths for data exchange in the second storage partition 22. The wired connection offers high-speed and stable data transmission capabilities, suitable for large file transfers; the wireless connection provides greater ease of use, suitable for real-time synchronization of everyday photos and documents. The authentication module 43 is associated with the external data storage function; any request attempting to access the second storage partition 22 via wired or wireless means must first pass authentication by the authentication module 43. This prevents unauthorized devices from accessing the extended storage area, protecting user privacy data, and also avoids the risk of interference or data leakage to the first storage partition 21 caused by abnormal external connections. Furthermore, because the first storage partition 21 and the second storage partition 22 are independent, the recording device 10 will not experience stuttering or data loss issues during recording and / or data storage.

[0038] Specifically, the main control module 1 serves as the control center of the entire system. For example, when the recording function is triggered, the main control module 1, after controlling the processing of the recording information, will store the processed data in the first storage partition 21. When an external device initiates a connection via wired or wireless means, the main control module 1 will wake up the corresponding communication interface and require verification by the verification module 43. Only after successful verification will access to the second storage partition 22 be granted. The unified scheduling by the main control module 1 ensures the orderly execution of the two major functions of recording and extended storage, avoiding idle storage space resources of the existing recording device 10. For example, the main control module 1 can adopt the Hengxuan 2800HP main control chip. Based on the advantages of the main control chip's high integration, low power consumption, and multi-protocol support, it can realize functions such as storage partition isolation, integration of dual communication modules 4, intelligent scheduling, and security authentication. The integration of dual communication modules 4 is mainly divided into wired transmission and wireless transmission. The wired transmission method can be a universal serial bus, such as USB-C interface connection, Micro-USB, Mini-USB, or Lightning interface connection. Wireless transmission can be achieved through Wi-Fi, Bluetooth, NFC, UWB, etc. In one possible implementation, for example, to achieve an extremely thin and light recording device 10, the Type-C port could be removed and replaced with another charging cable to charge the recording device 10. In this case, data transmission can be performed wirelessly. Alternatively, a dedicated transmission cable can be designed for wired transmission, allowing users to choose between wired and wireless transmission. In another possible implementation, a pogo pin interface can be used, enabling simultaneous charging and data transmission.

[0039] For example, when the main control module 1 does not receive recording information from the recording module and external data storage information from the wired connection module or the wireless connection module at the same time, the main control module 1 is used to convert the recording information into audio information separately and store the audio information in the first storage partition 21, or, the main control module 1 separately stores the external data storage information in the second storage partition 22.

[0040] For example, when the main control module 1 receives recording information from the recording module and external data storage information from the wired connection module or the wireless connection module at the same time, the main control module 1 is used to simultaneously convert the recording information into audio information, store the audio information in the first storage partition 21, and store the external data storage information in the second storage partition 22. Understandably, in this invention, the EMMC is divided into two independent partitions. For example, in an embedded Linux system, its device nodes can be identified as: First storage partition 21: corresponding to device node such as mmcblk0p1; Second storage partition 22: corresponding to device node such as mmcblk0p2; where mmcblk0 represents the EMMC storage chip in the device, and p1 and p2 represent the first and second physical partitions on the chip, respectively. Each partition has an independent physical address range on the EMMC flash memory medium, managed by the storage controller inside the main control chip through a partition table. Through the above partitioning method, complete isolation between the two regions is achieved at the physical storage level. When performing read and write operations, the main control module 1 strictly adheres to the physical address range corresponding to each partition: ensuring that the processed audio information is only written to mmcblk0p1; and that external data storage information transmitted via wired or wireless means by external devices is only written to mmcblk0p2. This isolation of physical address ranges ensures that even if one partition suffers data corruption or access abnormalities due to abnormal operations, file system errors, or partial hardware failures, the data integrity and normal access of another partition will not be affected. For example, frequent read and write operations or unexpected power outages on the extended storage partition (p2) will not affect the recording files already stored in the recording partition (p1).

[0041] Furthermore, the storage controller and driver software integrated within the main control module 1 are responsible for maintaining the partition table and completing the mounting and verification of each partition during system initialization. During operation, including recording mode for recording and extended storage mode for data transmission, the main control module 1 ensures that data flow is strictly directed to the corresponding partition through storage access control logic, based on the recording mode or extended storage mode. This ensures data isolation while also achieving efficient scheduling and secure management of storage resources.

[0042] It should be understood that simply partitioning without hardware-level coordinated control can lead to resource contention for storage media when recording and external data transmission occur simultaneously or alternately, resulting in dropped recording frames, transmission stutters, slow system response, or even system crashes. This embodiment can run both recording mode and extended storage mode simultaneously. For example, the address spaces of the first storage partition 21 (mmcblk0p1) and the second storage partition 22 (mmcblk0p2) are configured as independent regions in the main controller's memory management unit. The main control module 1 runs a dual-channel storage driver. The recording channel is directly connected to p1, and its driver is a high-priority, low-latency real-time task; the data channel is directly connected to p2, and its driver supports large-block data transmission protocols. When recording and transmission are triggered simultaneously, the internal scheduler of the main control module 1 assigns a higher fixed priority to recording to ensure the continuity of recording is not disrupted. While ensuring the minimum necessary write bandwidth for recording data, the scheduler dynamically allocates the remaining eMMC interface bandwidth to the data transmission task. For example, a recording task might only require a stable 10MB / s bandwidth, while the eMMC interface can reach a peak bandwidth of 200MB / s. The remaining bandwidth can be flexibly allocated to file transfer, enabling "recording and backing up simultaneously" without any noticeable lag. The main control module 1 is responsible for controlling the simultaneous or alternating recording and external data transmission. Therefore, the main control module 1 can link two different modes, allowing for recording only, data transmission only, or simultaneous recording and data transmission.

[0043] Specifically, please combine Figure 1 and Figure 2The verification module 43 includes a first verification module 431 and a second verification module 432. The main control module 1 includes a connection terminal 11, a first information input terminal 12, a second information input terminal 13, a third information input terminal 14, a first information output terminal 15, a second information output terminal 16, and a third information output terminal 17. The connection terminal 11 is connected to the first verification module 431 and the second verification module 432 respectively. The output terminal of the recording module 3 is connected to the first information input terminal 12 of the main control module 1, and the first information output terminal 15 is connected to the first storage partition 21. The main control module 1 receives recording information from the recording module 3, converts the recording information into audio information, and stores the audio information in the first storage partition 21. The output terminal of the wired connection module 41 and... The second information input terminal 13 of the main control module 1 is connected, the second information output terminal 16 is connected, and the second storage partition 22 is connected. The main control module 1 receives external data storage information from the wired connection module 41 and controls the first verification module 431 to perform verification. After successful verification, the main control module 1 stores the external data storage information in the second storage partition 22. The output terminal of the wireless connection module 42 is connected to the third information input terminal 14 of the main control module 1. The third information input terminal 14 is connected to the second storage partition 22. The main control module 1 receives external data storage information from the wireless connection module 42 and controls the second verification module 432 to perform verification. After successful verification, the main control module 1 stores the external data storage information in the second storage partition 22.

[0044] Understandably, the recorded information is transmitted to the main control module 1 through the first information input terminal 12, while external data is transmitted to the main control module 1 through the second information input terminal 13, which is independent of the first information input terminal 12. In this embodiment, the main control module 1 performs the conversion of the recording into audio information and stores the generated audio information in the first storage partition 21. First, using the audio processing unit and computing core integrated in the main control chip, the speech recognition task is completed in real time while the data is written into the main control module 1, converting the audio signal into digital audio information. The generated audio information is stored in the first partition. When querying recordings, users no longer need to listen to the audio content from beginning to end. They can quickly locate the corresponding time point of the recording in the audio information by searching for keywords in the application on the electronic device, realizing rapid retrieval of the recording content. In addition, the audio information is more easily read, edited, and utilized by other office software or data analysis tools. Specifically, the path for external data storage information is as follows: it enters through the second information input terminal 13 or the third information input terminal 14, and is stored in the second storage partition 22 after being verified by the first verification module 431 or the second verification module 432. The complete separation of external data storage and recording information paths ensures that data from external devices cannot interfere with audio information. Specifically, the input methods for external data storage include wired and wireless connections, and only one connection can be selected during a single transmission. Therefore, the wired and wireless connections are connected to different input terminals of the main control module 1, and their output ports are also independent. The independent configuration of the first verification module 431 and the second verification module 432 isolates the two different risks associated with wired and wireless transmissions.

[0045] Specifically, the recording module 3 includes at least one air wave microphone 31 and a bone conduction microphone 32. The air wave microphone 31 and the bone conduction microphone 32 are respectively connected to the first information input terminal 12 of the main control module 1. Both the air wave microphone 31 and the bone conduction microphone 32 are used to collect external sounds and obtain recording information.

[0046] Understandably, the recording module 3 must include at least one airborne acoustic microphone 31 (typically a MEMS silicon microphone) and at least one bone conduction microphone 32. These two types of microphones operate based on completely different physical principles. The airborne acoustic microphone 31 is a sensor that picks up sound by detecting changes in sound pressure in the air. It can record all sound information in the surrounding sound field, including the target speaker's voice, other people's conversations, ambient background noise, echoes, etc., thereby providing a rich, natural, and complete original audio signal. In noisy environments such as markets, factories, and inside vehicles, the target speaker's voice is easily drowned out by strong background noise. Even with noise reduction processing by backend algorithms, the airborne acoustic microphone 31 is difficult to completely separate the sound, leading to a decrease in recording clarity and subsequent speech recognition accuracy. Specifically, the bone conduction microphone 32 does not pick up sound through the air, but rather by fitting closely to the speaker's skin, usually on the neck, cheekbone, or in front of the ear, directly detecting the mechanical vibration of the vocal cords transmitted through the bones and soft tissues during speech, and converting this vibration into an electrical signal, thus possessing inherent physical noise immunity. Since ambient air noise is almost impossible to transmit efficiently through solid media, the signal collected by the bone conduction microphone 32 consists of the speaker's own voice, and the noise from the external environment has little interference.

[0047] For example, the recording device 10 in this embodiment includes five MEMS silicon microphones and one bone conduction microphone. The array of five silicon microphones enables 360° sound pickup and beamforming. The recording device 10 can have both normal recording and call recording scenarios. For example, when taking meeting notes in a quiet conference room, the recording device 10 operates in normal recording scenario, using only the airborne acoustic microphone 31 to obtain recordings with better sound quality across the entire scenario. When the device detects a sudden increase in ambient noise, or when the user manually switches to call recording scenario, the main control module 1 can dynamically increase the weight of the bone conduction microphone 32 signal, thereby ensuring that the speaker's voice can be clearly captured even in noisy environments.

[0048] Furthermore, the recording device 10 also includes a power module 5 and an interaction module 6. The power module 5 is electrically connected to the wired connection module 41 and the main control module 1, respectively. The interaction module 6 includes a display screen 61, an indicator light module 62, and a vibration motor module 63. The display screen 61, the indicator light module 62, and the vibration motor module 63 are electrically connected to the main control module 1, respectively.

[0049] Understandably, the power module 5 is electrically connected to both the wired connection module 41 and the main control module 1. When the device connects to an external mobile phone via the wired connection module 41, such as a USB or Type-C interface, and performs data transmission, this connection cable not only serves as a data path but also acts as a power cord, allowing an external charger to charge or directly power the power module 5 within the recording device 10. Furthermore, during high-speed wired data transmission or long-term recording backup operations, the device can simultaneously receive power replenishment, effectively preventing unexpected interruptions in data transmission or forced termination of recording tasks due to depletion of the built-in battery. The interaction module 6 consists of a display screen 61, an indicator light module 62, and a vibration motor module 63, and is connected to the main control module 1. The main control module 1 can control the indicator light module 62 to emit different colors or flashing patterns to intuitively indicate macroscopic device statuses such as "recording," "data transmission," "standby," or "error / alarm," facilitating quick confirmation of the recording device 10's status by the user.

[0050] Specifically, the display screen 61 can be a TFT screen, OLED screen, or LED screen. For example, when activating wireless transmission mode, the display screen 61 can dynamically generate and display a connection password or a QR code for quick pairing. Users can complete the wireless connection verification by entering the connection password or scanning the QR code on their mobile phones, simplifying the connection process. Simultaneously, the display screen 61 can also display more detailed information, such as remaining storage space, battery level, current recording duration, or transmission progress percentage, facilitating users' need to be aware of the device's deeper status. The vibration motor module 63 adds a silent tactile feedback dimension. For example, when meeting recording begins, in addition to the slight light emitted by the indicator light, a slight vibration can inform the user that "recording has started," avoiding the light attracting the attention of others. When the user operates the buttons to switch modes or complete verification, the vibration feedback provides a definite sense of confirmation, especially when the user's gaze is not focused on the device; touch provides the user with a perceptual means.

[0051] Please combine Figure 1 and Figure 3 The second embodiment of the present invention also provides a recording device storage method for recording and storing data of an electronic device. The recording device storage method includes the following steps: S1. Provide a recording device and start the recording device to enter standby mode; S2. Obtain external recording information and / or external data storage information of electronic devices; S3. If the recording device acquires recording information, it processes the recording information to obtain an audio signal, and then stores the processed audio signal in the first storage partition of the storage module. S4. If the recording device obtains external data storage information, it performs verification processing based on the external data storage information. If the verification fails, the recording device returns to standby mode. If the verification succeeds, the external data storage information is stored in the second storage partition of the storage module.

[0052] Understandably, in existing technologies, recording devices are typically used as single-function recording devices, with their large-capacity eMMC storage space remaining idle most of the time. When users attempt to reuse this storage space for other purposes, the lack of systematic process management and security controls often leads to direct conflicts between the recording function and the extended storage function in terms of resource access, causing system lag or even data loss. Simultaneously, unrestricted access to the storage space by external devices also poses risks of data leakage and tampering.

[0053] It should be understood that this embodiment divides the storage module into two independent storage partitions. Specifically, in step S2, the device starts up and enters a low-power standby mode. Standby mode is not a power-off state, but a listening state that can respond to external trigger events at any time. In standby mode, the control module is in a low-power sleep or minimized operation state, such as the press start signal of the recording button, the connection detection signal of the USB interface, or the wireless pairing button signal, so that the device consumes very little power during most non-use times, meeting the long battery life requirements of portable devices, while preparing for the immediate wake-up of subsequent functions. In step S2, the recording device can trigger a recording task or an external data transmission task independently at the same time, or it can perform both recording and external data transmission tasks simultaneously. In step S3, after the recording task is triggered, the recorded information is directly processed and stored in the first storage partition. The path in step S3 is closed and unidirectional, providing security for the information that needs to be stored. In step S4, a verification process is introduced for the external data storage path. If the verification fails, the process will terminate immediately, the device will directly return to low-power standby mode, and external access will be completely denied. Verification establishes a security barrier before the data writing operation, effectively preventing any unauthorized access attempts, regardless of whether they come from a wired or wireless interface. Only if the verification is successful will the data be allowed to be written to the independent second storage partition. This embodiment creates a boundary between the recording information and the external data storage information, ensuring isolation between the two in terms of physical storage location and access permissions.

[0054] Specifically, in step S2 above, starting the recording device to enter standby mode also includes: When the recording device enters standby mode, it verifies the first and second storage partitions to obtain their storage information. Based on the storage information, it generates the storage status of the recording device and sends the storage status to the electronic device. After sending the storage status, it returns to standby mode.

[0055] Understandably, by automatically executing a verification process each time the device enters standby mode, the verification primarily checks the file system integrity of each storage partition, confirms whether the partition capacity matches the preset or previously recorded capacity, and scans and records the used and remaining space of each partition. Through this verification process, the device can proactively detect minor data corruption that may be caused by abnormal power outages, improper disconnection, or software errors, and record or attempt to repair it before the problem escalates, thus maintaining the two storage partitions. Specifically, the main control module integrates the storage information obtained from the verification, such as partition size, used space, and file system status flags, into a storage status report. This storage status report transforms the device's own status from internal parameters into explicit information that can be understood and used externally. The storage status report is then sent to the electronic device. For example, when a user connects to the recording device via a mobile app, the app can immediately receive this storage status report and intuitively display information such as "Recording partition remaining XX GB, extended storage partition remaining XX GB," or prompt "Extended partition file system is normal and safe to use." This greatly improves the transparency and user control, allowing users to grasp the storage status without guessing or performing tedious manual queries.

[0056] Furthermore, in step S3 above, processing the recording information to obtain an audio signal includes: sequentially performing signal fusion, noise reduction optimization, and encoding on the recording information to convert the recording information into an audio signal.

[0057] Understandably, when a device is in recording mode, different microphones, such as silicon microphone arrays for pickup and bone conduction microphones for capturing pure human voices, simultaneously generate multiple independent analog or digital audio streams. These signals are synchronized in time but differ in content, phase, amplitude, and the noise components they contain. Signal fusion intelligently integrates these multiple signals into one or a few more representative main signals based on a preset algorithm strategy. For example, in a conference scenario, the fusion algorithm might calculate the correlation between the signals from each microphone, enhancing the speech components from the speaker's direction and suppressing interference from other directions; in a call mode with bone conduction microphones enabled, the algorithm might use the bone conduction signal as the primary reference, supplementing or enhancing it with the silicon microphone signal. Noise reduction optimization deals with audio signals that have undergone preliminary fusion but still contain a large amount of unwanted noise components. This noise may originate from ambient background noise, circuit background noise, or echoes. Noise reduction optimization analyzes and filters the signal in the frequency domain or time-frequency domain by applying digital signal processing algorithms. The goal is to separate and attenuate non-speech components in the signal as much as possible, while preserving and enhancing the clarity and naturalness of the speech components. Encoding converts the high-quality linear PCM audio signal, after fusion and noise reduction, into a more compact format suitable for long-term storage and specific purposes. Examples include the ".asr" format specifically for speech recognition, or the more common MP3 or WAV formats. The audio signal in this embodiment is in ".asr" format, which has the advantage of small memory footprint and can be directly read and converted into text readable on a mobile phone screen. The ".asr" format is not ordinary perceptual audio encoding, but is optimized for the characteristics of speech signals. It may preserve key speech features for recognition while discarding some details that are sensitive to the human ear but contribute little to machine recognition at a higher compression ratio. Encoding significantly reduces the final storage space occupied by the audio data, allowing for longer storage of recordings within the limited EMMC capacity. Furthermore, the generated ".asr" file itself prepares the data for subsequent speech recognition text conversion. The ".asr" file format typically embeds metadata or specific structures that are beneficial for the recognition engine, thereby improving the efficiency and accuracy of text conversion.

[0058] Specifically, the external data storage information is obtained through a wired or wireless connection between the recording device and the electronic device. In step S4 above, the verification process based on the external data storage information includes: Determine how external data storage information is obtained; If external data storage information is obtained through a wired connection, the recording device sends a verification command to the electronic device through the wired connection and receives the verification result returned by the electronic device. If the verification fails, the recording device returns to standby mode. If the verification succeeds, the external data storage information is stored in the second storage partition of the storage module. If external data storage information is acquired via wireless connection, the recording device displays a verification command and accepts the verification result returned by the electronic device. If the verification fails, the recording device returns to standby mode. If the verification succeeds, the external data storage information is stored in the second storage partition of the storage module.

[0059] Understandably, to determine the method of acquiring external data storage information, in one implementation, if the recording device is connected to the electronic device via a wired connection, the recording device, as the controlled end, can actively send a verification command to the electronic device via the wired connection. The main control module will send an authentication request to the connected mobile phone or computer through the established USB communication link. The user needs to complete the interaction on the companion application on the mobile phone, such as entering a preset password, using biometrics, such as fingerprint or facial verification, or completing device fingerprint matching. Subsequently, the electronic device returns the verification result to the recording device through the same wired link. This fully utilizes the stable characteristics of wired connections. The entire verification interaction process occurs on an established private physical link, which is not easily intercepted or interfered with by external third parties. For example, an AES-256 hardware encryption unit can be used, and the transmission of verification commands and results can be encrypted with high strength, further ensuring the security of the authentication process itself. If the verification fails, the main control module will immediately terminate the session and return to standby, effectively preventing unauthorized access.

[0060] Furthermore, in another implementation, for wireless connections such as those established via Wi-Fi or Bluetooth, after activating the Wi-Fi hotspot, the device dynamically generates and displays a QR code or random password on its integrated display screen. The user needs to scan the QR code or enter the password with their mobile phone to connect to the hotspot, and may complete further secondary confirmation within an app. Before establishing a trusted wireless link, there is a lack of secure communication between the device and the mobile phone. Therefore, displaying a dynamic password or QR code, whose information is instantaneous and unique, effectively prevents the risk of password leakage. The user can complete the verification by scanning with their mobile phone camera, and the user's active scanning is considered a participatory authentication, increasing the credibility of the operation. The subsequent verification result is returned through the newly established wireless link. If authentication fails, the device will immediately shut down the wireless module and return to standby mode to prevent the hotspot from being continuously cracked.

[0061] Specifically, activating the recording device into standby mode also includes: if the recording device and the electronic device are simultaneously establishing a wired or wireless connection, the connection between the recording device and the electronic device is determined to be a wired connection. It should be understood that in one implementation, a user might be performing high-speed file backup using a USB cable while the device's previously enabled Wi-Fi hotspot remains active; or, while the device is connected to a computer for charging via USB, the user might initiate a wireless connection request from a mobile app. In such abnormal or boundary conditions with dual communication links coexisting, the recording device prioritizes a wired connection. Wired connections typically provide a more stable, lower latency, higher bandwidth, and less susceptibility to environmental interference. The connection itself often indicates that the user may be performing a conscious operation with higher requirements for transmission speed or reliability. Furthermore, when the device is connected via wired connection, its power supply is usually guaranteed, which is beneficial for continuous data reading and writing. In another implementation, the file transfer verification mechanism is as follows: In scenarios where a file is transferred from a mobile device to a mobile device, the mobile device first calculates the hash value (e.g., MD5) of the file to be transferred and temporarily stores this value. After the file is transferred to the device, the device recalculates the hash value of the received file and sends it back to the mobile device. The mobile device compares the hash values ​​calculated by both ends; if they match, the file transfer is considered complete and error-free. Conversely, when a file is transferred from a device to a mobile device, the device first calculates the hash value of the file and sends it to the mobile device. After the file transfer is complete, the mobile device calculates the hash value of the received file and verifies it with the hash value sent by the device; if they match, the transfer is confirmed to be successful. The above verification method is not limited to the MD5 algorithm; other integrity verification methods such as SHA series hash algorithms, checksums, or error-correcting codes can also be used. Furthermore, the verification and comparison operation can be performed by either the mobile device or the mobile device, and the specific implementation method can be flexibly determined according to the system design.

[0062] To clearly demonstrate the use of the recording device in this embodiment, the following example is provided: A1. Device Initialization: Start the recording device.

Audio Recording Data Storage: The main control module stores the audio information in ".asr" format into the first storage partition, and at the same time controls the LED indicator to stay blue, indicating that it is in recording mode.

[0064] A7.

A8.

[0068] A12. Wired transmission ends: When the wired connection is disconnected or the transmission is completed, the main control module locks the second storage partition, and the recording device returns to standby mode.

[0069] A13. Assuming wireless transmission is triggered: When the user presses the Wi-Fi pairing button, the main control module activates the internal Wi-Fi 6 module or Bluetooth 5.3 module, and the recording device is in AP mode.

[0070] A14. Wireless ready to connect: The recording device releases a WPA3 encrypted hotspot, the display shows the dynamic paAAword, and the control LED indicator flashes yellow, indicating the wireless ready to connect status.

[0071] A15. Wireless Authentication: Connect your mobile phone to a Wi-Fi hotspot and complete secondary authentication via QR code scanning or Bluetooth assistance.

[0072] A16.

[0073] A17. Wireless data transmission: Enables data interaction between the mobile phone and the second storage partition via a Wi-Fi antenna, and supports resume download.

[0074] A18. Wireless transmission ends: If Wi-Fi is disconnected, transmission is completed, or extended storage mode is exited, the main control module locks the second storage partition, turns off the Wi-Fi module and Bluetooth module, and returns to standby mode.
