[0047] This utility model proposes a multifunctional mobile phone holder.

[0048] Please see Figures 1 to 10 In one embodiment of this utility model, the multifunctional mobile phone holder includes:

[0049] The housing 100 includes a mounting surface 11 and a support surface 12 disposed opposite to each other, the mounting surface 11 being capable of being connected to a mobile phone;

[0050] The bracket module 200 is disposed on the support surface 12 and includes a bracket base 21 and a support frame 22 rotatably connected about a first axis 25. The bracket base 21 is rotatable about a second axis 26 on the support surface 12. The first axis 25 is parallel to the support surface 12, and the second axis 26 is perpendicular to the support surface 12.

[0051] A pickup module 300 is disposed in the housing 100, and the pickup module 300 is capable of picking up sound within at least 5 meters around the periphery of the housing 100;

[0052] The transmission module, located inside the housing 100, is used to realize the signal transmission between the microphone module 300 and the mobile phone.

[0053] The multi-functional mobile phone holder proposed in this utility model can support the mobile phone on the placement surface while simultaneously serving as a sound pickup device, improving the phone's sound pickup range and effect. Specifically, the mounting surface 11 connects the housing 100 to the back of the mobile phone, at which point the sound pickup module 300 inside the housing 100 can record sound around the phone. Since the sound pickup range of the sound pickup module 300 in the multi-functional mobile phone holder is at least 5 meters around the housing 100, while the mobile phone can only pick up sound within a range of 1 to 3 meters around its perimeter, the sound pickup range of the multi-functional mobile phone holder is greater than that of the mobile phone. Therefore, it can effectively improve the sound pickup range when the user uses the mobile phone as a recording and translation device, enhancing the integrity of the mobile phone's sound pickup in complex environments. When the sound pickup module 300 in the multi-functional mobile phone holder completes sound pickup, the audio is transmitted to the mobile phone through the transmission module. The APP software on the mobile phone can then perform real-time translation, speech-to-text conversion, production meeting minutes, and other tasks based on the audio.

[0054] Furthermore, when the mounting surface 11 is connected to the mobile phone, the support frame 22 can rotate around the first axis 25 to move away from the housing 100. At this time, the support frame 22, the housing 100, and the placement surface can form a triangular structure to support the mobile phone on the placement surface. At this time, the support base can also rotate around the second axis 26 on the housing 100 so that the mobile phone can be supported on the placement surface in a vertical or horizontal posture relative to the user. When the user holds the mobile phone to pick up sound, the support frame 22 can rotate around the first axis 25 to fit against the bracket base 21, making it easier for the user to hold the mobile phone. When the user raises the mobile phone to take pictures, the support frame 22 can also be rotated around the first axis 25 to move away from the housing 100, and the multi-functional mobile phone holder can be placed on the edge of the mobile phone to pick up sound from the periphery of the mobile phone.

[0055] Therefore, the multifunctional mobile phone holder proposed in this utility model can be used with mobile phones to meet the recording and translation needs in various scenarios. It can also be used as an external stand for mobile phones to meet daily usage needs. Moreover, the multifunctional mobile phone holder is small in size and light in weight, making it easy for users to carry.

[0056] It's worth noting that when the phone is connected to the internet, it can upload recordings to a cloud server. The cloud server's powerful computing resources and real-time updated corpus then facilitate translation, supporting more complex grammar, uncommon words, and specialized terminology. Even when the phone is offline, without a mobile network or Wi-Fi connection, translation can still be performed using the built-in offline translation engine and pre-downloaded language packs within the mobile app. Therefore, when used with a phone, the multi-functional phone holder can function as a standalone device for both recording and translation in offline scenarios.

[0057] In one embodiment, the transmission module includes a wireless transmission component and / or a wired transmission component. Specifically, the wireless transmission component includes at least one of a Bluetooth connection component and a WiFi signal connection component, and the wired transmission component refers to a transmission method that connects the multi-functional phone holder and the phone via a data cable to achieve data transmission. That is, the multi-functional phone holder can transmit recorded audio to the phone via data cable transmission, Bluetooth transmission, WiFi signal transmission, etc. In other embodiments, the transmission module may have only one of a wireless transmission component and a wired transmission component.

[0058] In one embodiment, the sound pickup module 300 includes a noise reduction component and a sound pickup component 31. That is, the multi-functional phone holder can reduce ambient noise during recording, enhance the clarity of the recorded speech, and help improve the recognition accuracy of the software in the APP after the recording is uploaded to the phone, thus enabling more accurate translation, text conversion, meeting minutes, and other functions. In other embodiments, a noise reduction component may not be included.

[0059] In one embodiment, the housing 100 is further provided with a sound pickup sidewall 14, and the sound pickup assembly 31 includes a directional pickup 311 disposed near the sound pickup sidewall 14. The directional pickup 311 is capable of picking up sound in a range of 10 to 25 meters in front of the sound pickup sidewall 14; the directional pickup 311 is also capable of picking up sound in a range of 5 to 10 meters around the periphery of the housing 100.

[0060] Specifically, the directional microphone 311 also includes a DSP-4 component (fourth-generation Digital Signal Processor), enabling the multi-functional phone holder to serve as an accessory that enhances the microphone function on the phone. In a quiet environment, it can pick up sound directionally within 20 meters in the direction of the microphone sidewall 14 and within 10 meters in the direction around the phone.

[0061] In noisy environments, with 60dB noise reduction achieved through the noise reduction components, the multi-functional phone holder can pick up sound directionally within 10 meters in the direction of the sound-collecting sidewall 14 and within 5 meters upwards in the circumferential direction of the phone. Furthermore, the directional microphone 311 can pick up sound within 15 meters in front of the sound-collecting sidewall 14 and within 9 or 8 meters in the circumferential direction of the phone. In other embodiments, a directional microphone may not be provided, and the sound-collecting components can uniformly pick up sound circumferentially around the housing.

[0062] It should be noted that since the microphone module 300 performs directional microphone pickup on the front of the microphone sidewall 14 on the housing 100, and the microphone sidewall 14 is located between the mounting surface 11 and the support surface 12, when the mounting surface 11 is connected to the mobile phone, the orientation of the microphone sidewall 14 is horizontal with the mounting surface 11, that is, the microphone pickup direction of the multi-functional mobile phone holder is horizontal with the extension direction of the mobile phone. When the mobile phone is placed on a table or other surface for microphone pickup, the orientation of the microphone sidewall 14 on the multi-functional mobile phone holder can be adjusted by rotating the mobile phone to achieve a better microphone pickup effect. When the user holds the mobile phone to shoot a video, the support frame 22 can be rotated around the first axis 25 away from the housing 100, and the multi-functional mobile phone holder can be placed on the edge of the mobile phone. By rotating the housing 100 around the second axis 26 relative to the support base 21, the orientation of the microphone sidewall 14 can be adjusted in the direction intersecting with the extension direction of the mobile phone, so that the microphone sidewall 14 on the housing 100 is oriented towards the microphone object to achieve a better microphone pickup effect.

[0063] In one embodiment, the multi-functional mobile phone holder also includes a main control board 400 disposed within the housing 100. The microphone module 300 and the transmission module are both disposed on the main control board 400. The main control board 400 also has a data transmission port 41, which is electrically connected to the transmission module and is exposed on the side wall of the housing 100. When using wired transmission, one end of the data cable is inserted into the data transmission port 41 on the multi-functional mobile phone holder, and the other end is inserted into the data transmission port 41 on the mobile phone to achieve the transmission of recorded files. Furthermore, the main control board 400 can compress the audio files recorded by the microphone module 31, and then process and store the data through a Flash plugin running on the main control board 400. Subsequently, the audio processed by the Flash plugin is transmitted to the mobile phone through a wireless or wired transmission component in the transmission module. After the mobile phone processes the audio, it performs translation, text conversion, and meeting minutes generation through software in the APP.

[0064] In one embodiment, the multi-functional mobile phone holder also includes a storage battery 500 disposed within the housing 100, the storage battery 500 being electrically connected to the data transmission port 41 and the main control board 400. That is, an external power source can charge the storage battery 500 through the data transmission port 41. Further, the data transmission port 41 includes a Type-C data transmission port 41. Further, the data transmission port 41 is exposed on the microphone sidewall 14. In other embodiments, the data transmission port 41 may also include an Android data transmission port 41.

[0065] In one embodiment, the housing 100 is made of metal and has a through-hole 111. A sealing member 112 is provided on the through-hole 111 to seal it. The sealing member 112 is made of a material that does not have electromagnetic shielding properties. The wireless transmission component is disposed inside the housing 100 near the through-hole 111. Specifically, the housing 100 is made of aluminum or aluminum alloy to make it lighter, which helps to reduce the overall weight of the multi-functional mobile phone holder and provides better protection for components such as the main control board 400 and the storage battery 500 inside the housing 100.

[0066] By providing a through-hole 111 and a non-electromagnetically shielded sealing element 112 on the housing 100, the weak wireless signal emitted by the functional phone holder due to the inherent electromagnetic shielding properties of the metal material can be significantly reduced, preventing the metal housing 100 from interfering with the speed and stability of data transmission. During the connection of the multi-functional phone holder and the phone using the wireless transmission component, the wireless signal can pass through the through-hole 111 and the non-electromagnetically shielded sealing element 112, which helps improve the stability of wireless data transmission by the Bluetooth or WiFi connection component. Furthermore, the sealing element 112 prevents dust or moisture from entering the housing 100 through the through-hole 111. The sealing element 112 is made of plastic or ceramic. Furthermore, the sealing member 112 blocks the through hole 111 from the inside of the housing 100. The sealing member 112 includes an abutting section 113 that abuts against the end face of the through hole 111 and a sealing section 114 that extends into the through hole 111 and abuts against the hole wall of the through hole 111. Furthermore, the through hole 111 is located on the mounting surface 11 to shorten the signal transmission distance. Furthermore, the surface of the housing 100 is covered with leather 13, or the surface of the housing 100 is covered with a coating or oxide layer. In other embodiments, the housing 100 may also be made of plastic.

[0067] In one embodiment, the multi-functional mobile phone holder further includes a button module 600. The button module 600 includes a button assembly 61 exposed on the support surface 12 and a secondary control board 62 electrically connected to the button assembly 61. The secondary control board 62 is also electrically connected to the main control board 400. The button assembly 61 enables control of the start / stop of the microphone function and switching between recording and translation functions. Further, the button assembly 61 includes a function switching button 611 and a start / stop button 612. The function switching button 611 is movable in a horizontal direction relative to the support surface 12, and the start / stop button 612 is movable along the thickness direction of the housing 100. The function switching button 611 can be toggled in different directions to switch between recording and translation functions, and the start / stop button 612 can be pressed to control the start / stop of the microphone module 300. Further, the button module 600 also includes status indicator lights 63 located on the function switching button 611 and the start / stop button 612 to display the status of the multi-functional mobile phone holder. In other embodiments, the button module 600 may be omitted, and the recording and translation functions, as well as the start and stop of the pickup module 300, may be achieved through an APP software on a mobile phone.
