Description

Technical Field

[0001] This invention relates to the field of router technology, specifically to a voice-controlled miniature router and its voice control system. Background Technology

[0002] A router is a hardware device that connects two or more networks. It acts as a gateway between networks and is a dedicated intelligent network device that reads the address in each data packet and then decides how to transmit it. In this era of rapid development of network devices, routers are one of the most common devices we see. The prior art CN201921765256.6 discloses a router, including a router top cover, a router housing fixedly connected to the lower part of the router top cover, a router bottom baffle fixedly connected to the lower part of the router housing, an indicator light fixedly connected to the upper part of the front of the router housing, a connection cable interface one fixedly connected to one side of the front of the router housing, a lower support suction cup fixedly connected to the lower part of the router bottom baffle, a connection cable interface two fixedly connected to the other side of the front of the router housing, a connection cable interface three fixedly connected to the middle of the front of the router housing, an antenna connecting rod fixedly connected to the front of the antenna connecting rod, an antenna top cover plate fixedly connected to the upper part of the antenna, a middle support plate fixedly connected to the inner side of the middle of the router housing, a vent hole opened in the lower part of the router housing, a motor support bracket fixedly connected to the lower part of the middle support plate, a motor fixedly connected inside the motor support bracket, and a fan fixedly connected to the lower part of the motor. Existing technology involves fixing a lower support suction cup to the lower part of the router's lower baffle. The lower part of the lower support suction cup is a circular pad. During use, the router is fixed to the desktop using the lower support suction cup. However, in common use, routers are often simply placed on the desktop, and touching them can cause them to shift in position, fall to the ground, and be damaged. Based on a review of existing technologies and actual product use, it has been found that existing routers mostly use a bolt-fixed encapsulated shell structure. This type of router structure requires finding and removing multiple sets of bolts during assembly and disassembly, which is time-consuming and inefficient, resulting in certain shortcomings. Furthermore, existing routers lack voice control capabilities, resulting in a poor overall level of intelligence during use. Summary of the Invention

[0003] The purpose of this invention is to provide a voice-controlled miniature router and its voice control system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a voice-controlled miniature router, comprising a front shell, a back shell on the back of the front shell, a recessed limiting groove on the inner edge of the back shell, a plurality of evenly distributed snap-fit ​​claws fixedly installed on the inner wall of the back shell, a limiting edge adapted to the recessed limiting groove fixedly installed on the back of the front shell, the limiting edge and the recessed limiting groove being in clearance fit, a plurality of fasteners fixedly installed on the inner wall of the front shell, a plurality of heat dissipation grooves on both sides of the outer surface of the back shell, and a plurality of internal mounting brackets fixedly installed inside the back shell.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The router of this invention utilizes a recessed limiting groove and a limiting edge strip to limit movement during the assembly of the back and front shells. This limiting structure effectively prevents movement of the shells during assembly, resulting in better limiting and assembly performance. This improves the assembly accuracy between the two shells, facilitates alignment, and enhances overall practicality. Meanwhile, the snap-fit ​​structure between the front and back shells allows for the snap-fit ​​fixing of the router housing. The aligned snap-fit ​​structure effectively improves the assembly speed of the router, providing a fast and precise assembly experience. Compared to traditional screw fixing, the housing of this invention does not require multiple screws during assembly; it can be quickly assembled by snap-fit, saving assembly time and providing a fast-assembly feature. Furthermore, disassembly and separation can be achieved simply by prying the housing to the sides, making it highly practical and easy to install. Furthermore, the voice control system of the present invention can use a microphone to collect external control audio, which is then converted into a signal by an analog-to-digital converter. The converted audio signal can be processed by a voice recognition unit for voice recognition, and the voice-recognized signal can be transmitted to the system control unit.

[0020] Please see Figure 1-4 One embodiment provided by the present invention: Example

[0021] A voice-controlled miniature router includes a front shell 1, a back shell 2 on the back of the front shell 1, a recessed limiting groove 4 on the inner edge of the back shell 2, and several evenly distributed locking claws 5 fixedly installed on the inner wall of the back shell 2. A limiting edge 6 adapted to the recessed limiting groove 4 is fixedly installed on the back of the front shell 1. The limiting edge 6 and the recessed limiting groove 4 are in clearance fit, so that the limiting edge 6 can be inserted into the recessed limiting groove 4. Through the limiting effect of the recessed limiting groove 4 and the limiting edge 6, the limiting structure can limit the front shell 1 and the back shell 2 when the back shell 2 is assembled with the front shell 1. This can effectively prevent the shell from moving when it is recessed during assembly, and has a better limiting assembly effect. This can improve the assembly accuracy between the two shells, facilitate limiting alignment, and enhance overall practicality. In order to finally snap and fix the front shell 1 and the back shell 2, several snap fasteners 7 are fixedly installed on the inner wall of the front shell 1.

[0022] When using this type of small router, if the front shell 1 and back shell 2 need to be assembled, the limiting edge 6 of the front shell 1 and the recessed limiting groove 4 of the back shell 2 can be aligned. The limiting structure can limit the front shell 1 and back shell 2, which can effectively prevent the movement of the shell during the assembly process and improve the assembly accuracy. After the recessed limiting groove 4 is aligned with the limiting edge 6, the front shell 1 can be manually pressed to close the front shell 1 and the back shell 2. During the pressing of the front shell 1, several locking claws 5 inside the back shell 2 can be engaged into the locking clips 7 of the front shell 1. Thus, the locking structure between the front shell 1 and the back shell 2 completes the locking and fixing of the router shell. Through the aligned pressing and locking structure, the assembly speed of the router of this invention can be effectively improved, and it has the practical effect of quick limiting assembly. Compared with the traditional screw fixing, the shell of this invention does not need to be fitted with multiple screws during assembly. It can be quickly assembled by pressing and locking, saving assembly time and having the practical characteristic of quick assembly. Moreover, when disassembling and separating, the shell can be quickly disassembled and separated by simply prying it to both sides. In actual use, it has the practical characteristic of quick disassembly and assembly, and the overall practicality is stronger.

[0023] In this embodiment, in order to improve the structural adaptability of the fastener 7 and the locking claw 5, the number of fastener 7 and the locking claw 5 are the same, and the positions of several fasteners 7 and locking claws 5 correspond one-to-one.

[0024] In this embodiment, please refer to the appendix to the specification for details. Figure 4As shown, the outer surface of the snap fastener 7 is provided with a ramp for snapping and guiding the flow. By providing a flow guiding ramp on the outer surface of the snap fastener 7, the flow guiding work can be effectively carried out during the snapping process of the snapping claw 5, thereby improving the smoothness of the snapping claw 5 snapping in, reducing structural obstruction, and having a better snapping and guiding effect.

[0025] In this embodiment, several heat dissipation slots 8 are provided on both sides of the outer surface of the back shell 2. The heat dissipation slots 8 can ensure the normal heat dissipation of the router of the present invention. Several internal mounting brackets 3 are fixedly installed inside the back shell 2.

[0026] In this embodiment, to improve the anti-slip properties of the desktop contact surface on the back of the router, please refer to the attached instruction manual for details. Figure 2 As shown, an anti-slip contact 9 is fixedly installed at the center of the back of the back cover 2, and anti-slip contacts 10 are fixedly installed at the four corners of the back of the back cover 2. The anti-slip contact 9 and the anti-slip contacts 10 are both made of anti-slip rubber material. In this way, the anti-slip contact 9 and the anti-slip contacts 10 can be placed in contact with the desktop, thereby effectively improving the anti-slip performance of the router on the desktop, preventing the router from slipping, and improving the anti-slip protection performance.

[0027] In this embodiment, a power connection port 11 is provided on one side of the back of the back shell 2. Example

[0028] A voice control system for a small voice-controlled router includes a microphone electrically connected to an analog-to-digital converter (ADC), the ADC electrically connected to a voice recognition unit, the voice recognition unit electrically interconnected with a system control unit, the system control unit electrically interconnected with a voice prompt feedback unit, the voice prompt feedback unit electrically connected to the ADC, and the ADC electrically connected to the router's speaker. In this system architecture design, the microphone can be used to collect external control audio, which is then converted into a signal by an analog-to-digital converter. The converted audio signal can then be processed by a speech recognition unit for speech recognition. The speech recognition signal can then be transmitted to the system control unit, which can issue control signals to complete the voice acquisition and control processing of the router. In actual use, it has a good voice recognition control effect, improves the intelligence of the router, and has an intelligent voice control effect. Meanwhile, the system of this invention is equipped with a voice prompt feedback unit. The voice feedback unit can decode and feedback the voice, which facilitates the tracing of the source of the control audio signal. It has a better control feedback effect and facilitates the fundamental tracing of the control signal. This facilitates the comprehensive management and use of the router and has a better tracing voice control effect, making it more practical overall.

[0029] The analog-to-digital conversion unit includes an ADC module and a DOC module. The ADC module is electrically connected to a microphone and a speech recognition unit, respectively. The DOC module is electrically connected to a voice prompt feedback unit and a speaker. The analog-to-digital conversion unit receives the input voice signal at its input end and converts it into a digital sampling signal that can be processed by the digital chip. At its output end, it converts the decoded digital voice signal into an analog audio signal and plays it through the speaker.

[0030] In this embodiment, the speech recognition unit includes an endpoint detection module, which is electrically connected to a feature extraction module. The feature extraction module is used to extract features from external speech to obtain key speech control information. The feature extraction module is electrically connected to a template storage module, which is electrically connected to a template analysis module. The template analysis module is electrically connected to a DTW template matching module. The DTW template matching module is electrically connected to both the feature extraction module and the recognition decision module. The recognition decision module is used to make a decision on the final control information of the speech to confirm the control information.

[0031] Speech recognition unit algorithm: Currently, microcontrollers (MCUs) or DSPs are commonly used as hardware platforms to implement speech recognition in consumer electronics products. This type of speech recognition mainly involves isolated word recognition, which has two implementation schemes: one is speaker-independent recognition based on the Hidden Markov Model (HMM) framework; the other is speaker-specific recognition based on the dynamic programming (DP) principle. In this embodiment, one of the two algorithms mentioned above can be used.

[0032] The template matching algorithm of the DTW template matching module is described below: DTW is a typical speaker-specific algorithm using dynamic time warping. To overcome the differences in natural speech rate, it uses dynamic time warping to match the template feature sequence and the speech feature sequence, compares the distortion between the two, and derives the basis for recognition decisions.

[0033] Suppose a stored term template includes M frames of cepstral features R={(m); m=1,2,A,M}; and the recognition feature sequence includes N frames of cepstral features T={(n); n=1,2,A,N}. Define frame local distortion D(ij) between r(i) and t(), D(i,j)=|r(i)-t(j). Through dynamic programming, find the path with the minimum cumulative distortion in the search path, i.e., the optimal matching result. Use the symmetric form DTW: (S(i-1,j-2)+2D(i,j-1)+D(i,j)S(i,j)=min, S(i-1,j-1)+2D(i,j)S(i-2,j-1)+2D(i-1j)+D(i,j); S(i-1,j-1)+2D(i,j); S(i-2,j-1)+2D(i-1j)+D(i,j); Where S(i,j) is the cumulative distortion and D(i,j) is the local distortion. When the dynamic programming process reaches the fixed node (NM), the normalized distance of the template dynamic matching can be calculated, and the recognition result is the template term with the smallest normalized distance: x=argmin{S(N,M,)}.

[0034] In this embodiment, the system control unit includes a system control module and an I / O communication module.

[0035] In this embodiment, the voice prompt follow-up unit includes a voice encoding module, which is electrically connected to an endpoint detection module and a voice follow-up module. The voice follow-up module is electrically connected to a voice decoding module, which is electrically connected to a DOC module and a voice prompt module. The voice prompt feedback unit consists of a DSP, flash memory (FLASH), and a codec (CODEC). The DSP is the core of the entire voice recognition module, responsible for voice recognition, voice encoding / decoding, and FASH read / write control. The advantages of the DSP are its fast processing speed, large memory space, and fast data exchange speed. It can be used to implement complex algorithms, improve recognition rate, reduce response latency, and achieve higher recognition performance.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
