[0022] To better understand the technical content of this utility model, the technical solution of this utility model will be further introduced and explained below with reference to the schematic diagram, but it is not limited thereto.

[0023] Reference Figures 1 to 3 , Figures 1 to 3 This invention illustrates a specific embodiment of the signal transmission device 10 for underwater sports according to the present invention. The signal transmission device 10 for underwater sports according to the present invention can work in conjunction with a smartwatch (such as...). Figure 4 As shown in the attached figure, in the embodiment shown, the signal transmission device 10 for underwater movement includes a housing 11, a control chip 13 disposed within the housing 11, and an antenna assembly. The housing 11 has a through slot 111 for the strap 21 of the smartwatch 20 to pass through. The antenna assembly is electrically connected to the control chip 13, and the operating frequency of the antenna assembly matches the operating frequency of the antenna of the smartwatch 20, so as to receive wireless audio signals from the smartwatch 20 through electromagnetic coupling. The control chip 13 is used to process the received wireless audio signals and is electrically connected to an audio interface 15 exposed outside the housing 11.

[0024] Based on the above design, when the signal transmission device 10 for underwater motion is used in conjunction with the smartwatch 20, the antenna assembly is tuned to match the operating frequency of the antenna of the smartwatch 20 to optimize electromagnetic coupling efficiency and reconstruct the signal transmission path, such as... Figure 4As shown, it can be mounted on the strap 21 of the smartwatch 20 through the through slot 111, which shortens the distance between the smartwatch 20 and the signal transmission device 10. That is, the distance between the wireless signal transmitter and the signal transmission device 10 is shortened by the physical structure. The Bluetooth signal emitted by the antenna of the smartwatch 20 first undergoes electromagnetic coupling with the antenna component in the present invention in the very near field region, which can capture the signal in a short distance, effectively improving the stability of the Bluetooth connection and reducing the occurrence of signal interruption. The signal current generated by coupling is transmitted to the control chip 13, which demodulates and decodes the signal. It can be transmitted to the audio output device for playback in a wired manner through its audio interface 15. That is, the long-distance transmission from the signal transmission device 10 to the human ear is completed through a stable wired connection, avoiding the attenuation of radio frequency signals by water over long distances. Through the near-field coupling capture and stable wired transmission mode, stable and real-time audio content can be enjoyed underwater, meeting the user's need to listen to streaming media audio in real time.

[0025] Preferably, the signal transmission device 10 further includes a flexible circuit board 12. The antenna assembly can be an inverted-F antenna etched on the flexible circuit board 12. The control chip 13 and the audio interface 15 are soldered onto the flexible circuit board 12. The output end of the antenna assembly is electrically connected to the signal input end of the control chip 13 through a microstrip line on the flexible circuit board 12, so that the signal current generated by the coupling of the antenna assembly is transmitted to the control chip 13 for processing through the traces of the flexible circuit board 12. The signal output end of the control chip 13 is electrically connected to the audio interface 15, and one end of the audio interface 15 is exposed outside the housing 11. In this invention, the housing 11 can be made of silicone material, and the control chip 13 can be a commonly used chip that can realize signal processing (including demodulation and decoding, etc.), which will not be described in detail here.

[0026] Continue to refer to Figure 1 and Figure 3 In some embodiments, the housing 11 is further provided with control buttons 16 electrically connected to the control chip 13. Preferably, the control buttons 16 may include a power button, a pause button, and a return button, etc. The control chip 13 transmits the control button signals to the smartwatch 20 through the antenna assembly. Understandably, a battery may also be provided inside the housing 11 to power the signal transmission device 10 for underwater movement and ensure the normal operation of the signal transmission device 10.

[0027] In some other embodiments, the signal transmission device 10 for underwater movement may further include a fixing strap made of silicone material. The fixing strap passes through the through slot 111 of the housing 11 and is detachably fixed to the smartwatch 20, so that the antenna assembly inside the housing 11 and the signal transmitter of the smartwatch 20 are within the near-field communication range. Specifically, in this embodiment, a nested ring may be provided on the fixing strap, and the fixing strap is detachably fixed to the watch strap 21 of the smartwatch 20 through the nested ring. That is, both the watch strap 21 of the smartwatch 20 and the fixing strap can pass through the nested ring, and a tight fit is achieved through the nested ring. Understandably, if the watch strap 21 of the smartwatch 20 is detachable, the watch strap 21 of the smartwatch 20 can also be removed, and the fixing strap passes through the housing 11 of the smartwatch 20 and the signal transmission device 10, thereby fixing the smartwatch 20 and the signal transmission device 10 to the fixing strap. The fixing strap can replace the function of the watch strap 21. The length of the fixing strap can be adjusted according to actual needs, so that the smartwatch and the signal transmission device 10 of this utility model for underwater sports can be worn together on the wrist or around the neck.

[0028] As can be seen from the above, when the signal transmission device 10 for underwater sports is used, that is, when working in conjunction with the smartwatch 20, the signal transmission link is reconstructed. Through near-field coupling capture and wired stable transmission, the long-distance transmission attenuation of radio frequency signals by water is avoided, and stable, real-time audio content can be enjoyed underwater, meeting the user's need to listen to streaming media audio in real time.

[0029] Meanwhile, this utility model can also provide a signal transmission device for underwater sports, which includes a smartwatch 20, an audio output device, and the signal transmission device 10 described in the above embodiments. The signal transmission device 10 is detachably fixed to the smartwatch 20 (e.g., Figure 4 As shown, it can be fixed to the watch strap 21 of the smartwatch 20 through the through slot 111, or it can be fixed to the smartwatch 20 through a fixing strap. The audio output device is a waterproof earphone, which is connected to the audio interface 15 through a physical wire to output audio. Preferably, the earbud of the waterproof earphone can also be designed as a three-layer silicone earbud structure, and a fixing member can also be provided on the physical wire. The fixing member can be, for example, Figure 5The fixing clip 30 shown can be made of silicone material. During use, the waterproof headphones are inserted into the audio interface 15 of the signal transmission device 10 worn on the user's hand via a physical wire. Since the distance from the wrist to the ear is relatively far, the physical wire can be fixed to the user's arm by the fixing clip 30, that is, a part of the physical wire is fixed between the user's arm and the groove wall of the clip 31 to prevent the physical wire from being pulled or tangled during vigorous exercise. Understandably, in some other embodiments, the fixing member can be a fixing clamp, which can clamp a part of the physical wire to the user's collar, which can also prevent the physical wire from being pulled or tangled during vigorous exercise and improve the user experience.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
