[0026] The implementation manners of the present invention will be described below in combination with relevant embodiments. The implementation manners of the present invention are not limited to the following embodiments, and the relevant necessary components involved in the present invention should be regarded as well - known technologies in the technical field, which can be known and mastered by those skilled in the technical field.

[0027] As Figures 1 to 9 shown, a wireless microphone capable of wireless internal recording includes a charging case 3, a wireless microphone 1 and an adapter 2 stored in the charging case 3. The charging case 3 includes a lower housing 31 and an upper cover 38 hinged to one side edge of the lower housing 31. The surface of the lower housing 31 is provided with a microphone charging slot 36 for accommodating the wireless microphone 1 for charging. A second charging post 35 is arranged inside the microphone charging slot 36. The wireless microphone 1 is arranged in the microphone charging slot 36. A storage slot 37 is arranged on the surface of the lower housing 31 at one end of the wireless microphone 1. The adapter 2 is arranged in the storage slot 37. The wireless microphone 1 includes a housing 11, a pickup 12 arranged at one end of the housing 11, a back splint 14 hinged to the bottom surface of the housing 11, and a first circuit board 13 arranged inside the housing 11. A windproof sponge sleeve 121 is sleeved at one end of the pickup 12. A rotating cavity 122 is arranged inside the windproof sponge sleeve 121. A windproof component 4 connected to the other end of the pickup 12 is arranged inside the rotating cavity 122.

[0028] In the structure of the present invention, the wireless microphone 1 can collect and record external audio and store it in the internal storage module, enabling users to record high-quality audio without being restricted by cables. Through the wireless transmission module, the wireless microphone 1 can establish a wireless connection with external devices such as mobile phones to achieve instant transmission of recording data. This wireless transmission method not only improves the convenience of data transmission but also allows users to use the wireless microphone 1 in a wider range of scenarios. The coordinated use of the adapter 2 further enhances the flexibility of data transmission, allowing the mobile phone to further transmit the recording data to the memory card 24 through the adapter 2, thus realizing the long-term storage and convenient transfer of the recording data.

[0029] In the structure of the present invention, the windproof component 4 can effectively improve the windproof performance of the wireless microphone 1. The windproof plate 41 can rotate in the rotation cavity 122 of the windproof sponge cover 121 and be fixed in different orientations by the engagement of the first fixed tooth 47 and the second fixed tooth 48, forming a semi-surrounding structure for the pickup 12, thereby effectively reducing the impact of wind noise on the recording quality and enabling the wireless microphone 1 to maintain a clear recording effect even in environments with high wind noise such as outdoors. At the same time, the built-in high-frequency filtering and noise reduction module in the wireless microphone 1 further improves the clarity of the recording. The high-frequency filtering and noise reduction module can filter out the high-frequency noise in the recording, and when used in conjunction with the windproof function, it can significantly improve the recording quality of the wireless microphone 1.

[0030] In the structure of the present invention, the charging bin 3 provides a convenient charging method for the wireless microphone 1 and the adapter 2. The microphone charging slot 36 and the storage slot 37 enable the wireless microphone 1 and the adapter 2 to be placed in the charging bin 3 in an orderly manner and be charged through the second charging post 35, ensuring the long-term battery life of the wireless microphone 1.

[0031] As one of the preferred embodiments of the present invention, as Figure 1 、 Figure 7 and Figure 8 shown, the upper cover 38 is provided with an upper microphone storage slot 39 for accommodating the wireless microphone 1 and corresponding to the microphone charging slot 36. The upper cover 38 is also provided with a storage slot 37 for accommodating the adapter 2 at one end of the microphone charging slot 36. The side edge positions of the upper cover 38 and the lower housing 31 are correspondingly provided with magnets 32 that can magnetically attract each other.

[0032] The upper microphone storage slot 39 designed on the upper cover 38 corresponds to the microphone charging slot 36. When the wireless microphone 1 is not in use, it can be conveniently placed in the microphone charging slot 36 and fixed and protected through the upper microphone storage slot 39 of the upper cover 38, which helps prevent the wireless microphone 1 from being damaged and ensures its stability during charging.

[0033] Meanwhile, the upper cover 38 is also provided with a storage groove 37 at one end of the microphone charging groove 36 for storing the adapter 2. In this way, the adapter 2 can also be properly stored and protected to avoid loss or damage.

[0034] Magnets 32 capable of magnetic attraction to each other are correspondingly arranged at one side edge positions of the upper cover 38 and the lower housing 31. This magnetic attraction design enables the upper cover 38 to be easily attached to or separated from the lower housing 31 without additional latches or buttons, effectively improving the convenience of the charging case 3 and ensuring its sealing performance.

[0035] As one of the preferred embodiments of the present invention, as Figure 7 and Figure 8 shown, the lower housing 31 includes a bottom shell 312 and a top cover 311 provided on the top of the bottom shell 312. At both ends of the inner side wall of the bottom shell 312, connecting clamping plates 313 are symmetrically erected. One end of the connecting clamping plate 313 is connected to the inner side wall of the bottom shell 312. At the corresponding position of the connecting clamping plate 313 on the lower surface of the top cover 311, a clamping groove capable of being clamped and connected to the other end of the connecting clamping plate 313 is provided. The other end of the connecting clamping plate 313 is clamped and connected in the clamping groove. The storage groove 37 and the microphone charging groove 36 of the lower housing 31 are provided on the upper surface of the top cover 311.

[0036] The connecting clamping plates 313 are symmetrically erected at both ends of the inner side wall of the bottom shell 312, and one end is firmly connected to the inner side wall of the bottom shell 312, while the other end is designed to be a clamping structure. The clamping groove is provided on the lower surface of the top cover 311 corresponding to the position of the connecting clamping plate 313. The other end of the connecting clamping plate 313 can be tightly clamped in the clamping groove, thereby realizing the stable connection between the top cover 311 and the bottom shell 312. Through the above clamping connection method, the top cover 311 can be relatively easily detached from the bottom shell 312, which is convenient for repairing or replacing the components inside the lower housing 31.

[0037] As one of the preferred embodiments of the present invention, as Figure 7 and Figure 8 shown, a third circuit board 30, a second storage battery 33 electrically connected to the third circuit board 30, a third power interface 34 provided on the surface of the lower housing 31 on the side hinged to the upper cover 38 and electrically connected to the third circuit board 30 at one end are provided inside the lower housing 31. One end of the second charging post 35 is electrically connected to the third circuit board 30, and the other end of the second charging post 35 is placed in the microphone charging groove 36. A first charging post 10 electrically connected to the first circuit board 13 at one end is provided inside the outer shell 11, and the other end of the first charging post 10 is placed on the surface of the outer shell 11 on the side hinged with the back clamping plate 14.

[0038] When the wireless microphone 1 needs to be charged, the user places it in the microphone charging slot 36. At this time, the first charging post 10 on the wireless microphone 1 contacts the second charging post 35 in the charging bin 3. Since the second charging post 35 is electrically connected to the third circuit board 30, and the third circuit board 30 is also electrically connected to the second storage battery 33, a power transmission path is formed. Specifically, the second storage battery 33 supplies power to the second charging post 35 through the third circuit board 30. When the first charging post 10 contacts the second charging post 35, the power is transmitted from the second charging post 35 to the first charging post 10. The first charging post 10 transmits the received power to the first circuit board 13. The first circuit board 13 is provided with a charging management module for controlling the power flow to the first storage battery 17 inside the wireless microphone 1, thereby charging it. At the same time, the third power interface 34 charges the second storage battery 33 through the charging management module.

[0039] As one of the preferred embodiments of the present invention, as Figures 2 to 4 shown, the wireless microphone 1 is provided with a housing 11. The housing 11 is provided with a first storage battery 17 and a first circuit board 13 electrically connected to the first storage battery 17. On the surface of one side wall of the housing 11, there is a first power interface 111 electrically connected to the first circuit board 13. On the surface of the other side wall of the housing 11, there are a power switch 18 and a wireless connection switch 19 that are opposite to the first power interface 111 and electrically connected to the first circuit board 13.

[0040] Furthermore, in the above structure, the first circuit board 13 is further provided with a high-frequency filtering and noise reduction module, a wireless transmission module, a storage module, and a first processing module.

[0041] Specifically, in the above structure, the first circuit board 13 serves as the control center of the wireless microphone 1, connecting and managing each functional module. The first power interface 111 is used to connect to an external power source to charge the first storage battery 17, enabling the wireless microphone 1 to be conveniently charged by a wired method when the power is insufficient. The power switch 18 controls the power on and off of the wireless microphone 1 to ensure that the user can start or stop the device at any time as needed. The wireless connection switch 19 controls the wireless connection between the wireless microphone 1 and a receiving device (such as a mobile phone). This design enables the user to easily turn on the wireless connection function when wireless recording is required.

[0042] The high-frequency filtering and noise reduction module of the first circuit board 13 performs high-frequency filtering and noise reduction processing on the audio signals collected by the pickup 12, reduces background noise and interference, improves the recording quality. The storage module is used to store the recording data. When the wireless microphone 1 is in the recording state, the processed audio signals will be stored in the storage module in real time. The wireless transmission module is responsible for wirelessly transmitting the audio data inside the storage module to the receiving device. The first processing module, as the core processor of the wireless microphone 1, is responsible for controlling the working processes of each module, including the acquisition, processing, storage, and transmission of audio signals, etc.

[0043] When the user needs the wireless microphone 1 to work, the user presses the power switch 18. The first battery 17 provides power for the first circuit board 13 and each module connected thereto. The pickup 12 collects external audio and transmits the collected analog audio signals to the high-frequency filtering and noise reduction module on the first circuit board 13. The high-frequency filtering and noise reduction module performs high-frequency filtering and noise reduction processing on the received analog audio signals, reduces background noise and interference. The processed analog audio signals are converted into digital audio signals and stored in the storage module.

[0044] When the user needs to transmit the audio data in the storage module, the user presses the wireless connection switch 19, and the wireless transmission module starts to work. It wirelessly transmits the digital audio signals in the storage module to the receiving device (such as a mobile phone, etc.). During or after the wireless transmission, the user can export the recording data in the storage module to a computer or other storage devices for saving or subsequent processing.

[0045] As one of the preferred embodiments of the present invention, as Figures 2 to 4 shown, a hinge seat 15 is connected between the bottom surface of the housing 11 of the wireless microphone 1 and one end surface of the back splint 14. One end of the hinge seat 15 is connected to the bottom surface of the housing 11 of the wireless microphone 1, and the other end of the hinge seat 15 is connected to one end of the back splint 14. A hinge shaft 151 is passed through the inside of the hinge seat 15, and a torsion spring 16 is sleeved outside the hinge shaft 151. Two arms of the torsion spring 16 are respectively in abutting contact with the bottom surface of the housing 11 of the wireless microphone 1 and one end surface of the back splint 14.

[0046] The back splint 14 cooperates with the outer shell 11 and can be clamped at the edge of the user's clothing to fix the wireless microphone 1 during the recording process, reduce the need for hand holding, and improve the convenience and stability of use. The hinge seat 15 is used to connect the outer shell 11 and the back splint 14. The hinge shaft 151 is arranged inside the hinge seat 15, and the torsion spring 16 is sleeved outside the hinge shaft 151. Its two arms are respectively in contact with the bottom surface of the outer shell 11 and one end surface of the back splint 14, and are used to provide a restoring force. When the user clamps the back splint 14 on the clothing, the elastic force of the torsion spring 16 will make the back splint 14 closely adhere to the outer shell 11, thereby increasing the wearing stability of the wireless microphone 1, helping to reduce the shaking and noise interference during the recording process, and improving the recording quality.

[0047] As one of the preferred embodiments of the present invention, as Figure 1 and Figure 9 shown, the adapter 2 includes a housing 21, a second circuit board 25 arranged inside the housing 21, a mobile phone connection port 22 and a memory card 24 symmetrically arranged on the upper surface of the housing 21. The mobile phone connection port 22 is electrically connected to the second circuit board 25. The memory card 24 is provided with a plug-in slot 23 on the upper surface of the housing 21, and the memory card 24 is electrically connected to the second circuit board 25 through the plug-in slot 23.

[0048] The adapter 2 is an intermediate device of the present invention, connecting the wireless microphone 1, the mobile phone and the memory card 24, and realizing the transmission and storage of audio data. The adapter 2 is provided with a second circuit board 25 inside the housing 21. The adapter 2 is also provided with a mobile phone connection port 22 and a memory card 24. The mobile phone connection port 22 is electrically connected to the second circuit board 25, allowing the mobile phone to perform data transmission with the adapter 2 through the mobile phone connection port 22 and supply power to the second circuit board 25. The wireless microphone 1 can transmit the recorded audio data to the mobile phone through the wireless transmission module, and then the mobile phone transmits these data to the memory card 24 through the adapter 2. The memory card 24 is electrically connected to the second circuit board 25 through the plug-in slot 23, which enables the user to conveniently insert or remove the memory card 24 to store or export the recording data.

[0049] As one of the preferred embodiments of the present invention, as Figures 3 to 6As shown, the windproof component 4 includes a windproof plate 41 disposed in the rotation cavity 122 of the windproof sponge sleeve 121 and semi - surrounding the pickup 12, a mounting plate 411 disposed at one side of the windproof sponge sleeve 121 and connected to the windproof plate 41, a mounting sleeve 42 fixedly sleeved on the surface of the end of the pickup 12 outside the windproof sponge sleeve 121, a connecting plate 44 for connecting the mounting sleeve 42 and the mounting plate 411, an arc - shaped fixing pressure plate 43 capable of fitting on the surface of the mounting sleeve 42, a lifting rod 45 passing through the mounting plate 411 and having one end connected to the arc - shaped fixing pressure plate 43, and a spring 46 movably sleeved outside the lifting rod 45 and disposed between the mounting plate 411 and the arc - shaped fixing pressure plate 43.

[0050] Further, in the above structure, a rotating ring groove 49 is circumferentially provided on the surface of the mounting sleeve 42. One end of the connecting plate 44 is connected to the mounting plate 411, and the other end of the connecting plate 44 is snap - fitted into the rotating ring groove 49 and can be limitedly slid within the rotating ring groove 49. A second fixing tooth 48 is circumferentially provided on the surface of the mounting sleeve 42, and a first fixing tooth 47 capable of engaging and fixing with the second fixing tooth 48 is provided on the surface of the arc - shaped fixing pressure plate 43.

[0051] The function of the windproof component 4 is to improve the windproof performance of the microphone, ensure the clarity of recording in outdoor or windy environments, and effectively reduce or eliminate the noise caused by wind, thereby improving the recording quality. During the recording process, through its unique semi - surrounding design and rotating fixing mechanism, the windproof component 4 effectively blocks the direct impact of the air flow on the pickup 12. At the same time, the adjustment function of the lifting rod 45 and the spring 46 enables the user to flexibly adjust the position and fixing state of the windproof plate 41 according to the actual situation.

[0052] Specifically, the windproof plate 41 is disposed in the rotation cavity 122 of the windproof sponge sleeve 121 and surrounds the pickup 12 in a semi - surrounding manner, so as to be able to block most of the air flow directly blowing towards the pickup 12 and reduce the noise caused by the air flow. The windproof plate 41 is connected to the connecting plate 44 through the mounting plate 411, and the connecting plate 44 can be limitedly slid within the rotating ring groove 49 of the mounting sleeve 42, enabling the windproof plate 41 to rotate within a certain range in the rotation cavity 122 to adapt to different wind directions and recording requirements. After the windproof plate 41 rotates to a suitable position, the arc - shaped fixing pressure plate 43 can be engaged and fixed with the second fixing tooth 48 on the surface of the mounting sleeve 42 through the first fixing tooth 47 on its surface, ensuring the stability of the windproof plate 41 during the recording process and preventing it from moving due to wind force or other factors.

[0053] The lifting rod 45 is inserted through the mounting plate 411 and is connected to the arc-shaped fixed pressing plate 43. By pulling the lifting rod 45 up and down, the user can easily adjust the position of the arc-shaped fixed pressing plate 43, thereby realizing the fixation or release of the windproof plate 41. The spring 46 is movably sleeved outside the lifting rod 45 and is placed between the mounting plate 411 and the arc-shaped fixed pressing plate 43. The elastic force of the spring 46 helps to maintain the close contact between the arc-shaped fixed pressing plate 43 and the mounting sleeve 42, ensuring the effective engagement of the first fixed tooth 47 and the second fixed tooth 48.

[0054] In addition, the windproof sponge sleeve 121 itself also has a certain windproof effect. When used in conjunction with the windproof component 4, it can further improve the windproof performance of the wireless microphone 1.

[0055] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
