Description

Technical Field

[0001] This utility model relates to the field of far-field voice pickup technology for electronic devices, and in particular to a far-field voice pickup structure and electronic device. Background Technology

[0002] Far-field voice, as a new type of interaction method, is based on the principle of human-computer interaction through human voice. Theoretically, it can completely free users' hands and get rid of the constraints of remote control. Therefore, it is increasingly favored by people. In particular, with the development and maturity of Internet, artificial intelligence (AI) and big data technologies in recent years, far-field voice has been rapidly implemented in various products.

[0003] Taking a television as an example, in order to realize the far-field voice function of the television, the pickup module, the mounting panel, and the protective mesh are key components in the far-field voice pickup structure of the television. The connection method and layout between them have a significant impact on the sound pickup effect. Usually, the protective mesh and the pickup module are directly connected to the mounting panel, but the sound inside the device may resonate with the protective mesh and the mounting panel. Resonance will cause changes in the intensity and frequency characteristics of the sound signal, thereby mixing unnecessary noise into the sound signal picked up by the pickup module, thus interfering with the pickup effect of the pickup module.

[0024] This utility model proposes a far-field speech pickup structure 100.

[0025] Please see Figures 1 to 3 In one embodiment of this utility model, the far-field voice pickup structure 100 includes a mounting panel 1, a pickup module 2, and a protective net 3. Two first connecting portions 11 are protruding at intervals on one side of the mounting panel 1. The pickup module 2 forms a second connecting portion 21, which is connected to the side of the mounting panel 1 facing away from the first connecting portion 11, so that the pickup module 2 and the mounting panel 1 form a first gap space 22. The two sides of the protective net 3 are respectively connected to the two first connecting portions 11, and a second gap space 31 is formed between the side of the protective net 3 facing the mounting panel 1 and the mounting panel 1.

[0026] In this utility model's technical solution, the mounting panel 1 is the supporting component of the entire far-field voice pickup structure 100. Two first connecting parts 11 are protruding from one side of the panel, spaced apart. These two first connecting parts 11 are used to fix the protective net 3, ensuring a certain gap between the protective net 3 and the mounting panel 1. The second connecting part 21 of the pickup module 2 is connected to the side of the mounting panel 1 opposite to the first connecting part 11, so that the pickup module 2 and the mounting panel 1 form a first gap space 22. The formation of the first gap space 22 can be controlled by adjusting the height of the second connecting part 21 on the pickup module 2. The arrangement of the first gap space 22 and the second gap space 21 enables the pickup module 2 to effectively pick up sound signals from a distance and then transmit the picked-up sound signals to a digital array. The data is processed by the processing module, and then the control module controls the equipment to take corresponding actions based on the processing results. The protective net 3 is usually made of metal mesh or plastic mesh material, which has good air permeability and acoustic performance, allowing sound to pass through smoothly, while protecting the internal components from dust and foreign objects. By forming a first gap space 22 between the pickup module 2 and the mounting panel 1, and a second gap space 31 between the protective net 3 and the mounting panel 1, the interference of sound inside the equipment transmitted to the pickup module 2 through the mounting panel 1 and the protective net 3 can be effectively reduced. This gap design makes the sound encounter an air layer during transmission. The damping effect of the air layer will significantly reduce the transmission intensity of the sound, thereby reducing interference noise and improving the pickup effect of the pickup module 2.

[0027] Specifically, please refer to Figure 4 and Figure 5 In one embodiment of the present invention, the far-field voice pickup structure 100 includes fasteners, a connecting post 12 is formed on the side of the mounting panel 1 facing away from the first connecting part 11, the pickup module 2 is formed with a connecting plate, and the fasteners pass through the connecting plate and the connecting post 12 to connect the mounting panel 1 and the pickup module 2; the second connecting part 21 includes the connecting plate. A connecting post 12 is provided on the side of the mounting panel 1 facing away from the first connecting part 11. The pickup module 2 is provided with a connecting plate. Fasteners (such as screws, bolts, etc.) pass through the connecting plate and the connecting post 12 to firmly connect the mounting panel 1 and the pickup module 2. This connection method ensures the stability and reliability between the pickup module 2 and the mounting panel 1. The second connecting part 21 includes a connecting plate, which is a key component for connecting the pickup module 2 and the mounting panel 1. Through the fastener connection, a first gap space 22 is formed between the pickup module 2 and the mounting panel 1, which optimizes the acoustic performance of the pickup module 2. The use of fasteners not only realizes the physical connection between the mounting panel 1 and the pickup module 2, but also forms the first gap space 22 to reduce the transmission interference of sound inside the device. This design improves the far-field sound pickup effect of the pickup module 2, while maintaining the compactness and stability of the structure.

[0028] Further, please refer to Figure 4 and Figure 5 In one embodiment of this utility model, the far-field voice pickup structure 100 includes two fasteners. Two connecting posts 12 are spaced apart on the side of the mounting panel 1 facing away from the first connecting portion 11. Two connecting plates are spaced apart on the pickup module 2. Each fastener passes through one connecting plate and one connecting post 12 to connect the mounting panel 1 and the pickup module 2. Each fastener passing through one connecting plate and one connecting post 12 ensures a stable connection between the mounting panel 1 and the pickup module 2. The double fixing by the two fasteners significantly improves the connection stability between the mounting panel 1 and the pickup module 2, effectively preventing loosening or displacement that may be caused by a single-point connection, and ensuring the stability of the pickup module 2 during use. Through the design of the two connecting posts 12 and the connecting plates, a first gap space 22 is formed between the pickup module 2 and the mounting panel 1. This gap space design effectively reduces the transmission interference of sound inside the device, thereby improving the far-field pickup effect of the pickup module 2.

[0029] More specifically, in one embodiment of this utility model, a first adhesive layer is provided on both sides of the protective net 3, and each first adhesive layer is bonded to a first connecting part 11. The design of the first adhesive layer ensures a firm connection between the protective net 3 and the mounting panel 1. Through the bonding method, a stable second gap space 31 is formed between the protective net 3 and the mounting panel 1, which can effectively reduce the transmission interference of sound inside the equipment. The protective net 3 is usually made of metal mesh or plastic mesh material, which has good air permeability and acoustic performance, allowing sound to pass through smoothly, while protecting internal components from interference from dust and foreign objects. In one embodiment, the protective net 3 can be connected to the first connecting part 11 by AB dispensing. AB dispensing is a common bonding process. After mixing two adhesives (A glue and B glue) and curing, a high-strength bonding effect is formed. This connection method not only provides good sealing performance, but also ensures a firm connection between the protective net 3 and the mounting panel 1, preventing loosening caused by mechanical vibration or external force, providing higher bonding strength and better durability, and is suitable for application scenarios requiring high reliability.

[0030] To further improve the sound pickup performance of pickup module 2, please refer to [link / reference]. Figure 2 and Figure 3In one embodiment of this utility model, the mounting panel 1 has a mounting groove 13, the pickup module 2 includes a pickup plate 23 and a bracket 24, the bracket 24 has a protrusion 241, the protrusion 241 is accommodated in the mounting groove 13 and has a gap with the side wall of the mounting groove 13; the pickup plate 23 has a pickup groove 231, the protrusion 241 has a first through hole 242 corresponding to the pickup groove 231, the protective net 3 has a second through hole 32 corresponding to the first through hole 242, the pickup plate 23 is connected to the protrusion 241; the bracket 24 has a second connecting part 21. The protrusion 241 of the bracket 24 is accommodated within the mounting slot 13 and forms a certain gap with the side wall of the mounting slot 13 to ensure the stability and flexibility of the pickup module 2 on the mounting panel 1. This fit not only provides stable mechanical support but also reduces interference in sound transmission through the gap design. The pickup plate 23 is connected to the protrusion 241 of the bracket 24 to ensure the overall structural stability of the pickup module 2. The bracket 24 provides mechanical support for the pickup plate 23. The pickup plate 23 has a pickup slot 231 for picking up sound signals. The protrusion 241 of 24 has a first through hole 242 corresponding to the pickup slot 231 to ensure that the sound signal can be transmitted smoothly. The protective net 3 has a second through hole 32 corresponding to the first through hole 242 to further ensure the smooth transmission of the sound signal. This corresponding design ensures the continuity and integrity of the sound signal during transmission, improves the sensitivity and accuracy of the pickup module 2, and the first through hole 242, the second through hole 32 and the pickup slot 231 are connected in a straight line to shorten the pickup distance and further improve the pickup effect.

[0031] Furthermore, in one embodiment of this utility model, the pickup plate 23 has two pickup slots 231, the protrusion 241 has two first through holes 242, and the protective mesh 3 has two second through holes 32. Each first pickup slot 231 is provided with one first through hole 242 and one second through hole 32. The two pickup slots 231 can pick up sound signals from different directions respectively, thereby realizing dual-channel sound pickup. This design can significantly improve the sensitivity and accuracy of sound pickup, especially in complex sound environments. By setting two pickup slots 231, the target sound and background noise can be better separated, thereby reducing interference and improving the accuracy of speech recognition. The two pickup slots 231 can be used in conjunction with beamforming technology to enhance sound signals from specific directions while suppressing noise from other directions. This technology can significantly improve the effect of far-field speech pickup, especially in noisy environments.

[0032] Please see Figure 5In one embodiment of this utility model, multiple limiting protrusions 14 are formed at intervals on the opposite side walls of the mounting groove 13, and the protrusions 241 abut against the limiting protrusions 14 for positioning. The limiting protrusions 14 abut against the protrusions 241 of the bracket 24 to ensure the precise position and stability of the pickup module 2 on the mounting panel 1. The design of the limiting protrusions 14 can effectively prevent the pickup module 2 from shifting or loosening during installation, thereby improving the reliability of the structure. Furthermore, the abutment between the protrusions 241 of the bracket 24 and the limiting protrusions 14 forms a stable mechanical limit while ensuring that a certain gap is formed between the protrusions 241 and the side walls of the mounting groove 13, reducing interference in sound transmission and ensuring the flexibility and acoustic performance of the pickup module 2 on the mounting panel 1.

[0033] Please see Figure 4 and Figure 5 In one embodiment of the present invention, the mounting panel 1 has two buckles 15 spaced apart on the side facing the bracket 24, and the bracket 24 has two slots 243 spaced apart, with each buckle 15 engaging in one of the slots 243. Each clip 15 engages within a slot 243, ensuring a secure connection between the pickup module 2 and the mounting panel 1. This engagement method not only provides stable mechanical support but also allows for quick installation and disassembly, improving construction efficiency and maintenance convenience. The design of the clips 15 and slots 243 allows the pickup module 2 to be quickly installed onto the mounting panel 1 without additional tools or complex connectors. This design also facilitates disassembly, maintenance, and replacement of the pickup module 2, reducing maintenance time and costs. The cooperation between the clips 15 and slots 243 ensures the stability of the pickup module 2 during use, preventing loosening due to mechanical vibration or external forces. Through the cooperation of the clips 15 and slots 243, a stable second gap space 31 is formed between the pickup module 2 and the mounting panel 1, effectively reducing interference from internal sound transmitted through the mounting panel 1 to the pickup module 2, and improving the far-field pickup effect of the pickup module 2.

[0034] To further improve the sound pickup effect, in one embodiment of this utility model, the far-field voice pickup structure 100 further includes a dustproof mesh and at least two second adhesive layers. The dustproof mesh is disposed between the protrusion 241 and the pickup plate 23. One second adhesive layer is bonded to the protrusion 241 and the dustproof mesh, and the other second adhesive layer is bonded to the dustproof mesh and the pickup plate 23, and is disposed in a way that avoids the pickup groove 231. The dustproof mesh is located between the protrusion 241 and the pickup plate 23, inside the pickup module 2. The dustproof mesh can effectively prevent dust and foreign objects from entering the pickup module 2, protect the pickup plate 23 and the pickup slot 231, extend the service life of the pickup module 2 and improve the pickup effect. The dustproof mesh is bonded to the protrusion 241 and the pickup plate 23 respectively through two second adhesive layers. The second adhesive layers are set to avoid the pickup slot 231, ensuring that the sound signal can pass smoothly through the pickup slot 231 without affecting the pickup performance. The adhesive layers achieve a tight connection between the dustproof mesh and the protrusion 241 and the pickup plate 23, ensuring the structural stability and acoustic performance of the pickup module 2.
