[0041] Example

[0042] The present application embodiment provides a cross pickup structure, combined with Figures 1 to 7 As shown, it includes: a structural body 1 and a pickup plate 2;

[0043] At least two sound pickup channels 10 and at least two mounting grooves 12 are formed in the structural body 1. One end of the sound pickup channel 10 is connected to the sound pickup hole 101 located on the outer surface of the structural body 1, and the other end of the sound pickup channel 10 is connected to the mounting groove 12 located inside the structural body 1.

[0044] Two sound pickup channels 10 that are arranged in a "V" shape and connected to the same mounting groove 12 form a V-shaped structure 11. There are at least two V-shaped structures 11 inside the structural body 1. The connecting line formed by the sound pickup holes 101 connected to each V-shaped structure 11 on the outer surface of the structural body 1 is a first connecting line 13. There are at least two first connecting lines 13 that intersect at one point.

[0045] The pickup piece 2 is detachably mounted in the mounting slot 12. The pickup piece 2 includes at least two pickup parts 21. After being mounted in the mounting slot 12, each pickup part 21 is respectively aligned with a different pickup channel 10 to achieve multi-angle cross pickup.

[0046] It can be understood that the sound collection direction and specific sound propagation direction between the pickup channels 10 of the V-shaped structure 11 of the same mounting groove 12 are different, which can enhance the accuracy of sound positioning, effectively avoid the influence of noise in the external environment by collecting sound from multiple angles, and enrich the three-dimensional sense and layering of the collected sound, thereby optimizing the sound collection quality.

[0047] The cross-setting of the pickup channels 10 in the V-shaped structure 11 also helps to reduce the sound capture distortion caused by the movement of the pickup structure or the sound source, and also helps to avoid the sound overlap or aliasing caused by multiple sound sources, thereby improving the pickup reliability of the pickup structure.

[0048] It can be understood that the sound pickup range of the sound pickup channel 10 of each mounting slot 12 is different. The connecting line formed by the sound pickup hole 101 of each V-shaped structure 11 on the outer surface of the structural body 1 is the first connecting line 13. Figure 2 , Figure 3 As shown by the dotted lines in the figure, at least two first connecting lines 13 intersect at one point; that is, the intersection of the sound pickup ranges between the installation grooves 12 and the V-shaped structures 11 is achieved, which can further increase the capture coverage of the sound source sound and improve the sound pickup ability of the sound pickup structure;

[0049] The sound source localization information can also be increased by cross-setting the pickup ranges between the multiple installation slots 12, which helps to determine the source of the sound. At the same time, it can also help to better separate the sound signal and reduce the impact of environmental noise on the recording quality, thereby capturing more sound details and making the recording effect more realistic and three-dimensional, meeting the needs of use in fields that require high-quality recording, such as music recording and film and television shooting.

[0050] Specifically, in some embodiments of the present application, two mounting grooves 12 are provided in the structural body 1, and each mounting groove 12 is respectively connected to two sound pickup channels 10, and the two sound pickup channels 10 are cross-arranged to form a V-shaped structure 11; the V-shaped structures 11 of different mounting grooves 12 are also cross-arranged with each other; of course, there is no restriction on the specific number of mounting grooves 12, sound pickup channels 10, and V-shaped structures 11, as long as they help to achieve cross-pickup.

[0051] Furthermore, combined with Figures 2 to 4 As shown, all first connecting lines 13 have the same length, and the sound pickup channels 10 connected to the same mounting slot 12 have the same length.

[0052] The lengths of the first connecting lines 13 are the same, that is, the distances between the pickup holes 101 connected to the V-shaped structures 11 are the same. In addition, the pickup channels 10 of the same mounting slot 12 are set to have the same length, so that the delays of the sound signals of different mounting slots 12 during transmission can be kept consistent, and the delays of the sound signals of the pickup channels 10 in the same mounting slot 12 during transmission can be kept consistent; this can effectively avoid phase misalignment or aliasing caused by delay differences, maintain the accuracy and consistency of the sound signals, reduce sound attenuation and distortion, and maintain the quality of the sound; at the same time, the same length of the pickup channels 10 also helps to reduce the complexity and cost of structural design and maintenance.

[0053] Furthermore, a surface of the structural body 1 on which the sound pickup holes 101 are arranged is a sound pickup hole surface 14 , all the sound pickup holes 101 are evenly distributed around the central area of ​​the sound pickup hole surface 14 , and the angles between adjacent first connecting lines 13 are the same.

[0054] The pickup holes 101 are evenly distributed in the central area of ​​the pickup hole surface 14, which can effectively receive sounds from all directions, improve the omnidirectionality of the sound pickup, and thus better capture the sound of the sound source, which is suitable for some application scenarios that require omnidirectional reception of the sound source sound; since the pickup holes 101 are evenly distributed, dead angles can be reduced, avoiding the inability to effectively receive sounds from certain directions due to limitations on the sound propagation path; the design with the same angle can improve the balance of sound reception, avoid the situation where the sound in certain directions is too strong or too weak, and make the received sound more balanced.

[0055] Specifically, in some embodiments of the present application, two first connection lines 13 are formed, and the angle between the first connection lines 13 is 90 degrees. Of course, there is no limitation on the specific angle setting;

[0056] It can be understood that if there are three installation grooves 12, and each installation groove 12 is connected to a V-shaped structure 11, there are three first connection lines 13, and the angle between adjacent first connection lines 13 can be set to 60 degrees.

[0057] Specifically, in some embodiments of the present application, one end of each sound pickup channel 10 is connected to and is only connected to one sound pickup hole 101 , and the other end of each sound pickup channel 10 is connected to and is only connected to one mounting slot 12 .

[0058] With the above design, each sound pickup hole 101 and sound pickup channel 10 are independent, so that the sound collected in each sound pickup channel 10 has a unique source, avoiding mutual influence, aliasing and interference between the collected sounds, and improving the clarity and accuracy of the sound.

[0059] Furthermore, the opening of the sound pickup channel 10 at one end close to the surface of the structural body 1 is smaller than the opening of the sound pickup channel 10 at one end close to the mounting groove 12, which can optimize the sound collection process. The small-area end of the sound pickup channel 10 can more accurately capture the sound of the sound source and improve the clarity, accuracy and realism of the sound. The large-area end of the sound pickup channel 10 can more effectively collect and integrate these sound signals, thereby improving the efficiency and quality of sound collection.

[0060] Furthermore, if Figure 1 As shown, the structural body 1 includes at least two detachable assembly components 15, which enhances the scalability and flexibility of the sound pickup structure;

[0061] One of the two assemblies 15 that can be combined with each other is provided with a protruding structure 31 , and the other one is provided with a recessed structure 32 that matches the protruding structure 31 , so that the assembly 15 can be combined by embedding the protruding structure 31 in the recessed structure 32 .

[0062] The design of the protruding structure 31 and the recessed structure 32 is simple and reliable, and they can be easily embedded and released from each other, providing a firm connection while achieving a convenient disassembly process.

[0063] Furthermore, if Figure 1 As shown, a first guide portion 41 is disposed at one end of the protruding structure 31 away from the assembly 15 where the protruding structure 31 is disposed, and a second guide portion 42 is disposed at one end of the recessed structure 32 away from the assembly 15 where the recessed structure 32 is disposed;

[0064] The first guiding portion 41 and the second guiding portion 42 are used to embed the protruding structure 31 into the recessed structure 32 along a predetermined direction.

[0065] Among them, the cross-sectional area of ​​the first guide portion 41 is smaller than the cross-sectional area of ​​the protruding structure 31, and the first guide portion 41 gradually narrows in the direction away from the assembly 15. The cross-sectional area of ​​the second guide portion 42 is larger than the cross-sectional area of ​​the recessed structure 32, and the second guide portion 42 gradually narrows in the direction approaching the assembly 15, so that when the protruding structure 31 is about to be engaged with the recessed structure 32, even if the relative position of the protruding structure 31 and the recessed structure 32 is not accurate enough, under the guiding action of the specific shapes of the first guide portion 41 and the second guide portion 42, the protruding structure 31 can be smoothly embedded in the recessed structure 32 to complete the combination between the assemblies 15.

[0066] Furthermore, if Figure 4 , Figure 5 and Figure 7 As shown, the pickup plate 2 is provided with slots 22 connected to different pickup parts 21 , and the slots 22 are used to connect all the pickup channels 10 of the same installation slot 12 .

[0067] By setting the slot 22, the pickup channels 10 corresponding to different pickup parts 21 on the pickup plate 2 can be connected, and then the different pickup holes 101 can be connected, so that the sound can be smoothly transmitted to the pickup plate 2 without being blocked by obstacles; at the same time, by collecting sounds through multiple pickup channels 10 at the same time, more sound details and spatial information can be captured, and the three-dimensional effect and realism of the sound can be improved.

[0068] Furthermore, if Figures 4 to 6 As shown, a stepped accommodation space 16 is formed in the structural body 1;

[0069] The mounting grooves 12 are distributed in different areas on the outer wall of the accommodating space 16 so that the pickup plates 2 are relatively separated in position.

[0070] By designing the accommodating space 16 in a stepped shape and dividing the accommodating space 16 into different areas, the mounting grooves 12 can be located at different positions of the accommodating space 16, so that the pickup plates 2 are relatively separated in position, which can reduce cross-interference between the pickup plates 2. Even if the accommodating space 16 is relatively limited and the pickup plates 2 are relatively close to each other, cross-interference of sound and reduction in sound quality are unlikely to occur, thereby improving the clarity and accuracy of the sound.

[0071] Furthermore, the included angle between the sound pickup channels 10 of the V-shaped structure 11 is between 40 degrees and 100 degrees.

[0072] The angle between the sound pickup channels 10 of the V-shaped structure 11 will affect the final sound pickup effect. When the angle between the sound pickup channels 10 is too small, phase interference may occur, affecting the clarity and accuracy of the sound. When the angle between the sound pickup channels 10 is too large, the sound source may not be accurately identified, and too much noise may be collected, which may also affect the clarity and accuracy of the sound. Therefore, it is necessary to set a reasonable range for the angle between the sound pickup channels 10.

[0073] The design of controlling the angle of the pickup channel 10 of the V-shaped structure 11 between 40 degrees and 100 degrees can enhance the perception of the direction of the sound source, thereby enhancing the accuracy of sound positioning and reducing phase interference; it can also increase the comprehensiveness of sound collection and capture sounds from different directions and angles, thereby improving the integrity and authenticity of the sound; it can also make the sounds captured by different pickup channels 10 more independent and clear, reduce overlapping recordings between pickup channels 10, and optimize the sound mixing effect, which is beneficial to later sound processing and mixing, thereby improving the pickup performance and effect.

[0074] The setting of the above-mentioned angle range ensures sufficient distinction between the various sound pickup channels 10, which can avoid too large a gap between sound sources due to too large an angle, and can also avoid too much mutual interference due to too small an angle; it balances the comprehensiveness of sound collection and the accuracy of sound positioning, thereby improving the comprehensive performance of the sound pickup structure.

[0075] Preferably, the included angle of the sound pickup channel 10 is controlled between 50 degrees and 60 degrees.

[0076] Furthermore, the shape of the sound pickup channel 10 includes any one of a cylindrical shape and a prism shape.

[0077] The linear cylindrical or prismatic arrangement of the sound pickup channel 10 can make the sound pickup path more direct, reduce factors that may cause sound distortion or reverberation, thereby improving the clarity of the sound; it can also reduce the impact of ambient noise from different directions on the sound, and improve the anti-interference ability of the sound pickup device.

[0078] An embodiment of the present application also provides an audio device, comprising a cross pickup structure of any one of the first part.

[0079] By way of example, common audio devices include microphones, earphones / headphones, microphones, audio recording equipment, sound cards, etc.

[0080] The audio device is equipped with a cross-pickup structure, which can create a more three-dimensional and natural sound field, enrich the auditory experience, and effectively reduce the interference of ambient noise from different directions on the sound quality, thereby improving the clarity and purity of the sound.

[0081] Other similar contents are not repeated here.

[0082] The embodiments of the present application have at least the following beneficial effects:

[0083] The embodiment of the present application provides a cross-pickup structure and an audio device having the same, which can effectively reduce interference from the external environment, enhance the positioning and capture of the sound source, and improve the sound capture quality; specifically, through the cross-setting between the pickup channels 10 of the same mounting slot 12 and the cross-setting between the pickup ranges of different mounting slots 12, a wider sound space is created, the three-dimensional sense and layering of the sound are enhanced, the precise positioning and capture of the sound source sound is achieved, and the auditory experience is improved.
