Description

Technical Field

[0001] This utility model relates to the field of audio recorder technology, specifically a multi-functional integrated WIFI audio recorder. Background Technology

[0002] With the widespread adoption of mobile office, remote collaboration, and smart home scenarios, the demand for portable recording devices integrating wireless transmission and audio processing functions has surged. Traditional recording devices typically employ wired connections or single-function module designs, making it difficult to meet users' needs for multi-scenario adaptability, high sound quality, and intelligent interaction. In the existing technology, some manufacturers have launched audio recorders supporting Wi-Fi / Bluetooth connectivity, such as wireless recorders that upload audio to mobile phones via Wi-Fi. However, extended functions rely on USB or dedicated interfaces, and external microphones require physical plugging and unplugging, which can easily cause interface wear and tear, making them inconvenient to use. Alternatively, built-in voice assistants and microphone arrays are mainly used for near-field voice command recognition, with insufficient far-field pickup accuracy, resulting in inconvenience and limitations. Therefore, those skilled in the art provide a multi-functional integrated Wi-Fi audio recorder to solve the problems mentioned in the background technology. Utility Model Content

[0022] Please see Figures 1-4 In this embodiment of the utility model, a multi-functional integrated WIFI audio recorder includes a functional component 1, an AI processing chip 2, and an external component 4. The functional component 1 includes a device body 11, with an SD card slot 15 located at the upper right side surface of the device body 11, and the external component 4 located in the middle right side of the device body 11. Microphones 121, 222, 323, and 424 are respectively located at the four corners of the outer surface of the device body 11. A camera 13 is electrically connected to the upper outer surface of the device body 11, and two supplementary light slots 111 and 112 are symmetrically arranged on either side of the camera 13. The supplementary lighting slot 111 is electrically connected to an LED bead 12, and the lower part of the camera 13 is embedded with a display screen 14. The external component 4 includes a magnetic power contact +41 and a magnetic power contact -43. A magnetic data contact 42 is set between the magnetic power contact +41 and the magnetic power contact -43. A power switch 20 is set at the lower end of the right outer surface of the device body 11, and a solar panel 3 is embedded at the upper end of the outer surface of the device body 11. A speaker 19 is set at the middle of the left outer surface of the device body 11, and an intercom switch 18 is electrically connected at the lower end of the left outer surface of the device body 11. A fixing clip 31 is fixedly connected at the upper end of the rear outer surface of the device body 11, and a charging port 34 is electrically connected at the lower end of the outer surface of the device body 11. A battery cover 16 is fastened to the rear outer surface of the device body 11, and a cover bolt 17 is fastened to the middle of the upper end of the battery cover 16. The device body 11 contains a WIFI antenna 35, an AI processing chip 2, a main controller 32, and a battery 33.

[0023] The working principle of this utility model is as follows: When using this utility model, firstly, the operator presses the power switch 20. At this time, the device is powered on and starts up. The supplementary light bulb 12 and the camera 13 automatically start to record. The image captured by the camera 13 will be immediately displayed on the display screen 14. At the same time, the MIC121, MIC222, MIC323 and MIC424 located at the four corners of the outer surface of the device body start to work. The AI ​​processing chip 2 uses beamforming algorithm to accurately calculate the direction of the sound source through time difference and phase difference, and then dynamically enhances the target direction signal and suppresses noise from other directions. This effectively solves the problem that the existing built-in voice assistant and its microphone array are mainly used for near-field voice command recognition, and the far-field sound pickup accuracy is insufficient, making it inconvenient to use and having certain limitations. At this time, the image and audio recorded by the device are processed by the main controller 32 and then stabilized by the WIFI antenna 35. The data is transmitted to a cloud server for subsequent evidence retrieval. If an external extended recording microphone is needed on-site, it can be effectively magnetically connected through the magnetic power contact +41, magnetic power contact -43, and magnetic data contact 42 in the external component 4. The positioning groove 44 can be embedded with the external microphone to prevent misalignment and complete the long-distance sound acquisition task. This perfectly solves the problem that existing sound pickup extension functions rely on USB or dedicated interfaces, and external microphones need to be physically plugged in and unplugged, which can easily cause interface wear and is inconvenient to use. In addition, the device has a walkie-talkie function. Just press the walkie-talkie switch 18 to communicate with collaborators in real time. The device is also equipped with a solar panel 3. Just point the solar panel 3 to a sunny place to charge it at any time. This can play an emergency role even when it is difficult to obtain power in complex scenarios. This utility model is convenient to use and deserves to be vigorously promoted.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
