[0042] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0043] The following will be described in detail Figures 1 - 7 , through specific embodiments and their application scenarios, the recording pen provided by the embodiments of the utility model.

[0044] As Figure 1 , Figure 2 and Figure 7 shown, an embodiment of the present utility model provides a recording pen, including: a housing 1, a main board 2, a camera module 3 and a microphone module 4;

[0045] The housing 1 has a receiving cavity, the main board 2, the camera module 3 and the microphone module 4 are respectively arranged in the receiving cavity, a receiving interval 40 for receiving the camera module 3 is arranged on one side of the microphone module 4, and at least part of the camera module 3 is arranged in the receiving interval 40;

[0046] The camera module 3 includes a camera 31, a flash 32 and a flexible circuit board 33; the camera 31 and the flash 32 are respectively connected to the flexible circuit board 33; the flexible circuit board 33 and the microphone module 4 are respectively connected to the main board 2.

[0047] It can be understood that the housing 1 can be in a flat strip structure, so that an operator can hold the housing 1, pick up ambient sound signals based on the microphone module 4, and capture images of the current environment based on the camera module 3. Among them, the camera module 3 and the microphone module 4 can be either separated from each other or in contact with each other; the camera module 3 and the microphone module 4 can be arranged in layers along the first direction as shown in Figure 2 shown, or can be arranged on the same layer along a direction perpendicular to the first direction.

[0048] The microphone module 4 is configured with a microphone and a sound receiving cavity matching the microphone. During use, there is no need to debug the microphone module 4. As long as the microphone module 4 is installed in the receiving cavity, the sound signals of the surrounding environment can be normally picked up based on the microphone module 4.

[0049] In some examples, the microphone can be an omnidirectional microphone, and multiple omnidirectional microphones form an omnidirectional microphone array. The omnidirectional microphone array can be used for 360-degree omnidirectional sound pickup in a recording scenario, and a moving coil microphone, a ribbon microphone, a silicon microphone, etc. can be used. Taking the silicon microphone as an example, it has good consistency, and the adaptive distance can reach 3-5 meters, which can meet the recording requirements of small scenarios.

[0050] In some examples, the microphone can be a directional microphone, also known as a super-directional microphone, which can only pick up sound in a single direction, and is more sensitive to the ambient sound signals in the pick-up direction than the ambient sound signals in other directions. The directional microphone can adopt a capacitive microphone, such as a microelectromechanical microphone, an electret condenser microphone, etc. The directional microphone can be applicable to a directional long-distance high-fidelity sound pickup scenario, and the recording sound quality and recording fidelity of the directional microphone are much higher than those of the silicon microphone.

[0051] Of course, the microphone module 4 can also include a combination of an omnidirectional microphone and a directional microphone. Since the ambient sound signals picked up by the omnidirectional microphone array can be used for noise reduction of the ambient sound signals, and the directional microphone is used for directional mode sound pickup, which has good directivity, the ambient sound signals in other directions such as the reverse direction will be physically filtered out. Therefore, through the cooperation of the directional microphone and the omnidirectional microphone array, a better sound pickup effect can be achieved.

[0052] Meanwhile, a groove can be formed on one side of the microphone module 4, and the internal space of the groove forms an accommodation section 40. By accommodating the camera module 3 in the accommodation section 40, the camera module 3 and the microphone module 4 can be compactly assembled together, reducing the space occupied by the two.

[0053] For the camera module 3, the camera 31 and the flash 32 can be arranged side by side. Both the camera 31 and the flash 32 are arranged on the upper side of the flexible circuit board 33 and are electrically connected to the flexible circuit board 33; the flexible circuit board 33 can be detachably connected to the main board 2 by using a BTB connector; wherein, the flash 32 is used to supplement light to the shooting environment of the camera 31 to ensure the shooting effect of the camera 31.

[0054] In some examples, during the use of the recording pen, while recording with the microphone module 4, the camera module 3 can be used to take images of paper manuscripts or images on the display screen, etc. The taken images can be processed by the main board 2 for image recognition, image denoising, etc.

[0055] In addition, the main board 2 can be a Printed Circuit Board (PCB), and the signal lead-out wire of the microphone module 4 can also be electrically connected to the main board 2 in a plug-in manner; the main board 2 is provided with a processor and a wireless communication module. The processor is respectively communicatively connected to the camera module 3 and the microphone module 4 and is configured to communicate with a remote server through the wireless communication module; wherein, the processor has sufficient computing power to provide local image and voice recognition, and provide a transcribing service for voice information.

[0056] The recording pen provided by the present utility model can install the camera module 3 through the accommodation section 40 by arranging the accommodation section 40 on one side of the microphone module 4, and compactly assemble the camera module 3 and the microphone module 4 together, facilitating the miniaturization design of the recording pen; meanwhile, since the camera 31 and the flash 32 of the camera module 3 are respectively connected to the flexible circuit board 33, after fixing the camera 31 and the flash 32, the flexible circuit board 33 can be connected to the main board 2, thereby completing the one-time assembly of the camera module 3, and then wiring the microphone module 4, so as to quickly complete the assembly of the recording pen, and its operation is simple and convenient.

[0057] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 shown, the accommodation cavity includes a first cavity 11 and a second cavity 12; both the camera module 3 and the microphone module 4 are arranged in the first cavity 11, and the main board 2 is arranged in the second cavity 12;

[0058] The housing 1 is provided with a first opening 101 and a second opening 102 that communicate with the first cavity 11. The lens of the camera 31 and the light-emitting end of the flash 32 are respectively arranged opposite to the first opening 101, and the sound pickup end of the microphone module 4 is arranged opposite to the second opening 102.

[0059] It can be understood that the first cavity 11 and the second cavity 12 are isolated from each other. This design can separate the installation areas where the camera module 3 and the microphone module 4 are located from the installation area where the main board 2 is located, ensuring that these two parts do not affect each other.

[0060] To facilitate image acquisition and sound signal acquisition of the current environment, the first cavity 11 is formed at the head end of the housing 1, and the second cavity 12 is formed in the handheld area of the housing 1 for the operator to hold, for example, the handheld area is located between the head end and the tail end of the housing 1.

[0061] Furthermore, since the lens and the flash 32 are arranged side by side, the first opening 101 is arranged opposite to both the lens of the camera 31 and the light-emitting end of the flash 32 at the same time; when there are multiple microphones in the microphone module 4, the microphone module 4 has multiple sound pickup ends, and multiple second openings 102 can be provided, and the multiple sound pickup ends of the microphone module 4 are arranged opposite to the multiple second openings 102 one by one.

[0062] In some examples, as Figure 3 shown, there are two second openings 102, the first opening 101 is located between the two second openings 102, and the first opening 101 and the two second openings 102 are arranged along the circumferential direction of the housing 1.

[0063] In some embodiments, as Figure 2 、 Figure 4 and Figure 5 shown, the housing 1 has a first side wall 111 and a second side wall 112 that are arranged opposite to each other in the first direction;

[0064] The first opening 101 is provided on the first side wall 111, and the accommodation section 40 is formed on the side of the microphone module 4 facing the first side wall 111; one end of the camera module 3 abuts against the first side wall 111, and the other end abuts against the first side of the microphone module 4, and the second side of the microphone module 4 abuts against the second side wall 112.

[0065] It can be understood that the camera module 3 and the microphone module 4 are arranged in the first direction as Figure 2 shown, and the assembly formed by these two abuts between the first side wall 111 and the second side wall 112 of the housing 1. Among them, the first side of the microphone module 4 can also be configured to abut against the first side wall 111.

[0066] Since the accommodation interval 40 is formed on the side of the microphone module 4 facing the first side wall 111, this design ensures that the camera module 3 can collect images of the surrounding environment through the first opening 101, and at the same time realizes the compact cooperation of the camera module 3 and the microphone module 4 along the first direction, which is beneficial to reducing the size of the recording pen along the first direction.

[0067] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 shown, the recording pen further includes: a protective lens 6; the protective lens 6 is disposed at the first opening 101.

[0068] It can be understood that the protective lens 6 can be a transparent glass lens or a transparent resin lens. The protective lens 6 is adapted to the size and shape of the first opening 101, and the protective lens 6 is used to provide physical protection and prevent dust from entering the lens of the camera 31 and the light emitting end of the flash 32.

[0069] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 shown, the recording pen further includes: a first seal 100; the first seal 100 extends along the circumference of the first opening 101, and the first seal 100 is disposed between the first side wall 111 and the protective lens 6.

[0070] It can be understood that the first seal 100 is bonded between the first side wall 111 and the protective lens 6. The first seal 100 is used to remove the possible gap between the first side wall 111 and the protective lens 6 and prevent water from entering the housing 1 through the first opening 101.

[0071] Optionally, the first seal 100 can be a waterproof adhesive tape, and the waterproof adhesive tape is bonded between the first side wall 111 and the protective lens 6.

[0072] Optionally, a sunk groove is provided on the outer wall surface of the first side wall 111. The sunk groove extends along the circumference of the first opening 101. The first seal 100 is annular and is bonded to the bottom surface of the sunk groove. At least part of the protective lens 6 is embedded in the sunk groove and is bonded to the first seal 100 as a whole.

[0073] In some embodiments, such as Figure 3 and Figure 4 shown, a spacer 13 is provided in the housing 1. The spacer 13 divides the accommodation cavity into a first cavity 11 and a second cavity 12. The spacer 13 is provided with a through-hole for the flexible circuit board 33 to pass through;

[0074] The voice recorder further includes a second seal 200 which is arranged to extend along the circumference of the through - opening; the second seal 200 is disposed between the spacer 13 and the camera module 3.

[0075] It can be understood that the second seal 200 can be a waterproof foam. The waterproof foam abuts between the spacer 13 and the camera module 3; when the waterproof foam is squeezed, it will contract at the squeezed part, while the non - squeezed part of the waterproof foam remains in a natural fluffy state, so that the physical properties of the waterproof foam can be utilized to ensure a good waterproof sealing effect between the spacer 13 and the camera module 3.

[0076] In practical applications, first install the second seal 200 circumferentially at the through - opening on the spacer 13, and then pass the flexible circuit board 33 of the camera module 3 through the through - opening to assemble the camera module 3 and the microphone module 4; when assembling the camera module 3, the camera module 3 can be driven to move towards one side of the spacer 13 and squeeze the second seal 200 to ensure the waterproof sealing between the spacer 13 and the camera module 3 through the second seal 200, and prevent the moist air with possible water leakage in the first cavity 11 from entering the second cavity 12 through the through - opening.

[0077] Among them, the spacer 13 can be a partition board. The spacer 13 can be provided with a plurality of through - openings. One of the plurality of through - openings is used for laying the flexible circuit board 33, and the other parts of the plurality of through - openings are used for laying the signal lead - out wires of the microphone module 4.

[0078] In some embodiments, as Figure 1 、 Figure 4 and Figure 6 shown, the camera module 3 further includes a first bracket 34; the first bracket 34 abuts between the first side wall 111 and the microphone module 4; the camera 31 and the flash 32 are arranged on the first bracket 34.

[0079] It can be understood that the first bracket 34 can be a plastic bracket or a stainless - steel bracket, and the first bracket 34 is used to provide an installation support and physical protection for the camera 31 and the flash 32.

[0080] In some embodiments, as Figure 4 、 Figure 5 and Figure 6 shown, the first bracket 34 includes a first frame body 341 and a second frame body 342. The first frame body 341 and the second frame body 342 are arranged along the first direction and are detachably connected;

[0081] The camera module 3 further includes a third seal 300 disposed between the first frame body 341 and the second frame body 342. The camera 31 and the flash 32 are disposed within the accommodation space formed by the first frame body 341 and the second frame body 342.

[0082] It can be understood that by providing the first frame body 341 and the second frame body 342 to be detachably connected, it is convenient to quickly install the camera 31 and the flash 32 within the accommodation space formed by the first frame body 341 and the second frame body 342.

[0083] In some examples, such as Figure 6 shown, the first frame body 341 is disposed on the upper side of the second frame body 342 along the first direction. The first frame body 341 is provided with a tongue, and the second frame body 342 is provided with a bayonet. The tongue and the bayonet form an engaged snap structure; when assembling the first bracket 34, by driving the first frame body 341 to move towards the second frame body 342 along the first direction, the tongue can be inserted into the bayonet to achieve snap connection between the first frame body 341 and the second frame body 342.

[0084] Furthermore, the third seal 300 can be a waterproof foam. The third seal 300 abuts between one end of the first frame body 341 facing the second frame body 342 and one end of the second frame body 342 facing the first frame body 341; this design can prevent water leakage from the gap between the first frame body 341 and the second frame body 342.

[0085] Among them, the third seal 300 can be provided in a sheet shape, and the camera 31 and the flash 32 are disposed within the accommodation space formed by the first frame body 341 and the third seal 300.

[0086] Based on the solution shown in the above embodiments, three sealing structures are provided on the path from the first opening 101 to the through-opening. This design can ensure the waterproof requirements of the area where the camera module 3 and the main board 2 are located, and the waterproof test can pass the IPX5 waterproof rating.

[0087] In some embodiments, such as Figure 2 、 Figure 3 and Figure 4 shown, the housing 1 is further provided with an installation opening 103, and a sealing plate 5 is detachably provided at the installation opening 103;

[0088] The camera module 3 and the microphone module 4 enter the first cavity 11 through the installation opening 103; the camera module 3 has a first inclined surface 301, and the microphone module 4 has a second inclined surface 401. The first inclined surface 301 and the second inclined surface 401 are fitted together and abut against each other along the first direction.

[0089] It is understandable that when assembling the camera module 3 and the microphone module 4, first, the first inclined surface 301 of the camera module 3 is attached to the second inclined surface 401 of the microphone module 4, and then a force is applied to the microphone module 4 along the length direction of the housing 1, and the assembly formed by the camera module 3 and the microphone module 4 is pushed into the first cavity 11 from the installation opening 103. By utilizing the cooperation between the first inclined surface 301 and the second inclined surface 401, when the microphone module 4 is pushed in place, the assembly formed by the camera module 3 and the microphone module 4 can be automatically abutted between the first side wall 111 and the second side wall 112 of the housing 1. Then, a locking member is used to connect the microphone module 4 to the housing 1, and there is no need to fix the camera module 3 again. Finally, the installation opening 103 is encapsulated with a sealing plate 5; this design simplifies the installation steps of the camera module 3 and ensures the convenience and reliability of the installation of the camera module 3.

[0090] It should be noted here that in order to facilitate the microphone module 4 to pick up the sound signals in the surrounding environment, a sound pickup area can also be provided on the sealing plate 5, and the sound pickup area is arranged opposite to the sound pickup end of the microphone module 4. Among them, the sound pickup area is configured with a plurality of sound pickup holes.

[0091] In some embodiments, such as Figure 1 and Figure 7 shown, the microphone module 4 includes a second bracket 41, a first microphone, and a second microphone;

[0092] The second bracket 41 includes a first mounting portion 411, a connecting portion 412, and a second mounting portion 413 that are connected in sequence; an accommodating interval 40 is formed among the first mounting portion 411, the connecting portion 412, and the second mounting portion 413.

[0093] Specifically, the first mounting portion 411 is used to mount the first microphone and is configured with a sound receiving cavity that matches the first microphone; the second mounting portion 413 is used to mount the second microphone and is configured with a sound receiving cavity that matches the second microphone; among them, both the first microphone and the second microphone can be omnidirectional microphones or directional microphones.

[0094] At the same time, the first mounting portion 411 and the second mounting portion 413 are isolated from each other and are arranged side by side; a groove-like structure is formed among the first mounting portion 411, the connecting portion 412, and the second mounting portion 413, and the internal space of the groove-like structure is the accommodating interval 40 for accommodating the camera module 3, and the groove bottom surface of the groove-like structure forms the second inclined surface 401 of the microphone module 4, so as to realize the convenient installation of the camera module 3 based on the inclined surface cooperation between the first inclined surface 301 of the camera module 3 and the second inclined surface 401 of the microphone module 4.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
