[0079] Some embodiments of this disclosure provide a recording device, offering a more portable recording device with higher recording quality. Specifically, the reason for the low portability and poor recording quality of most recording devices is that most current voice recorders adopt traditional cylindrical or columnar designs. While these designs are fully functional, they often cause inconvenience. For example, most voice recorders cannot be easily carried with common smart devices (such as mobile phones and tablets), limiting their portability. Furthermore, the microphones built into most smart devices are often limited by the internal space structure, resulting in poor recording quality. Based on this, some embodiments of this disclosure provide a recording device including a main control unit, a power management unit, a housing, a microphone assembly, and a communication unit. The power management unit and the microphone assembly are disposed within the housing. The microphone assembly is configured to collect audio from different directions. The main control unit and the communication unit are also disposed within the housing. The recording device is configured to communicate with a target terminal via the communication unit. The aforementioned recording device is an external device, and the microphone assembly is not affected by the internal structural design of the smart device. Furthermore, the microphone assembly is configured to capture audio from different directions, thus improving the recording quality. Therefore, a recording device with improved audio acquisition quality is provided, enhancing the user experience.

[0080] Figure 6 This is a schematic diagram of another embodiment of the recording apparatus disclosed herein. Figure 5 It includes a built-in camera recess 15, a snap-fit ​​recess 151, a first movable hinge 152, an outer bracket 153, a second movable hinge 154, an inner bracket 155, a third movable hinge 156, and a miniature camera 157.

[0081] Figure 7 This is a schematic diagram of the groove cover in the closed state of another embodiment of the recording device disclosed herein. Figure 6 Includes grooved cover 16.

[0082] In some embodiments, such as Figure 6-7As shown, the aforementioned housing may further include a miniature camera 157, a movable camera bracket, a built-in camera recess 15, and a recess cover 16. The miniature camera 157 may be a CMOS miniature camera, without specific limitation. The miniature camera 157 may be wireless or wired. In the wired case, the connecting cable can be configured within the movable camera bracket to communicate with the recording device. The built-in camera recess 15 may have a locking recess 151 on its periphery. The recess cover 16 may be configured to engage with the built-in camera recess 15 via the locking recess 151, thereby protecting the internal miniature camera 157 and the movable camera bracket to a certain extent. The movable camera bracket may include an outer bracket 153 and an inner bracket 155. The area of ​​the outer bracket 153 is larger than the area of ​​the inner bracket 155. One end of the outer bracket 153 may be fixed to one end of the built-in camera recess 15 via a first movable pivot 152. One end of the outer bracket 153 can be connected to one end of the inner bracket 155 via the second movable pivot 154. The outer bracket 153 may have an opening for the inner bracket 155. When the movable camera bracket is retracted, the inner bracket 155 is configured to fit into the inner bracket 155 opening, further saving space occupied by the movable camera bracket. The inner bracket 155 may have a camera mounting hole. The shape of the miniature camera 157 can match the shape of the camera mounting hole.

The inner bracket 155 can be configured to rotate via the second movable pivot 154. The miniature camera 157 can be configured to rotate about the third movable pivot 156 as its central axis. All of the above rotation methods can be triggered manually or by other feasible physical means, and are not specifically limited here. The aforementioned miniature camera 157 is configured to communicate with the aforementioned main control unit so that the aforementioned recording device can acquire the function of recording video.

[0083] The aforementioned miniature camera and related structure, as an inventive point of this disclosure, solves the technical problem that "most recording devices lack video recording functionality, and devices with recording functionality have a single lens angle." The specific factors leading to the lack of video recording functionality in most recording devices and the single lens angle of devices with recording functionality are as follows: most voice recorders cannot connect to other electronic devices, therefore, to simplify their structure, most voice recorders typically do not include a camera unit, resulting in a relatively simple recording function and low versatility. Furthermore, recording devices with camera functionality usually have difficult-to-adjust lens angles, leading to poor flexibility. Solving these factors can add video recording functionality to the recording device, improving its versatility and flexibility. To achieve this effect, this disclosure also provides a recording device that works in conjunction with a movable stand and a miniature camera. On one hand, the movable stand and miniature camera are small and foldable, occupying minimal space and not affecting the portability of the recording device. On the other hand, the movable stand can be moved and adjusted in multiple stages, offering high flexibility. Thus, without affecting the portability of the recording device, a flexible camera structure is provided, improving its versatility and flexibility.

[0084] In some embodiments, the recording system described above includes, for example, Figure 1-7 The described recording device and a target terminal connected to the recording device, wherein the target terminal is used to display a recording request. The recording device may include, for example: Figure 1-7 The corresponding embodiments describe the main control unit, power management unit, housing 1, microphone assembly, and communication unit. The target terminal may include, but is not limited to, mobile phones, tablets, and computers. The connection methods may include, but are not limited to, wired and wireless connections, wherein the wireless connection methods may include, but are not limited to, Bluetooth, Wi-Fi, 5G / 4G, and NFC connections. The wired connection method may be via a USB data cable. The recording requests may include, but are not limited to, start, end, pause, and marker.

[0085] Some embodiments of this disclosure provide a recording system that offers high-quality audio capture and wide compatibility. Specifically, the poor audio quality and limited compatibility of most recording systems stem from the fact that most recording devices are built-in microphones in common smart devices, whose design is easily affected by the device's structure, resulting in poor audio recording quality. Furthermore, most recording devices can only be used with wired or wireless connections to the target terminal, limiting their compatibility. Therefore, some embodiments of this disclosure provide a recording system characterized by comprising, for example,... Figure 1-7The described recording device and target terminal connected to the recording device are used to display a recording request. On one hand, the recording system provides a way to improve the quality of the captured sound by using an external recording device, thus preventing the microphone array from being affected by the structure of the target terminal itself. On the other hand, the recording device can be connected to the target terminal in various ways, making it widely applicable. Therefore, a recording system with high-quality sound capture and wide applicability is provided, enhancing the user experience.
