[0031] In practical applications, the NFC sensing circuit can be used to enable watch A and watch B to sense and identify each other when they are close together, and then exchange data including device name, unique identification code, encrypted verification information and Wi-Fi or Bluetooth pairing information.
[0032] Once the watch receives the necessary networking information, it activates the corresponding Wi-Fi, Bluetooth modules, and NFC sensing circuits, and quickly establishes connections with other devices based on this information, completing the network setup. This process can be repeated to allow more watches (such as C, D, E, etc.) to join the existing network.
[0033] Once this smartwatch successfully networks with other watches, users can view a list of all devices on the network from any of the watches. It supports sending various types of files and data to single, multiple, or all watches, such as watch face designs, schedules, memos, reminders, text files, photos, videos, and audio. The recipient has the option to choose whether to accept the sent files.
[0034] Once this smartwatch successfully networks with other watches, it integrates the microphones of each watch into a single microphone array for sound pickup. During recording, the watch initiating the recording sends a reference clock signal to each participating watch via broadcast, ensuring real-time synchronization of all audio streams and avoiding sound issues caused by latency. Ultimately, all audio streams are merged into a single, complete recording file on the initiating watch, which can then be saved or further processed as needed.
[0035] In addition to directly saving audio files, this smartwatch can also transmit recordings to associated applications for advanced functions such as transcription, translation, or meeting summaries.
[0036] This intelligent networking and collaborative working mode between watches greatly enhances the ability of individuals and teams to share information and collaborate, especially when it is necessary to record meeting content or conduct remote collaboration.
[0037] The power management circuit manages and distributes power to the various components, ensuring efficient watch operation and enabling charging and battery monitoring. The motor control circuit generates vibration alerts, such as alarm reminders, incoming call vibrations, or other notifications. The recording button circuit provides the hardware support for users to start recording by pressing a button. The heart rate sensor circuit collects personal health data and activity information, such as steps, heart rate, and sleep quality. The firmware storage circuit stores the basic software code required for system operation, i.e., firmware, which typically includes the bootloader and operating system kernel. The audio file storage circuit is specifically used to save recorded audio files. The audio amplifier circuit enhances the sound signal, making the sound emitted through the speaker clearer and louder. The upgrade port circuit and USB interface circuit: these two are usually the same physical interface, used for both firmware updates (upgrade port) and data transfer and connection to a personal computer (USB interface). Multiple microphones mounted on the main control board improve recording quality, achieve better noise reduction, and support directional recording. The Bluetooth antenna mounted on the main control board sends and receives Bluetooth signals. In summary, this smartwatch can not only be used as a regular smartwatch, but also as an efficient meeting tool, providing high-quality recording, Bluetooth calling, and other health management features.
