Description

Technical Field

[0001] This utility model relates to the field of folding keyboard technology, specifically a three-fold multi-microphone array intelligent voice input keyboard device. Background Technology

[0002] With the popularization of computer technology, keyboards have become an important input device for office work, study, and entertainment. Folding keyboards are keyboards that can be folded when not in use. Their design is intended to make them easy to carry and store. They have multiple folding methods, such as vertical folding and horizontal folding, which is one of the most significant features of folding keyboards. They can be easily folded up and put into a bag without taking up much space. They are suitable for people who frequently need to go out for work, business trips, or travel, allowing users to unfold and use them anytime, anywhere, getting rid of the problem of traditional keyboards being bulky and inconvenient to carry.

[0003] Most common folding keyboards adopt a single-axis double-folding design, which is not enough to reduce the volume after folding. For example, the patent with the existing authorization announcement number "CN 206460417 U" discloses a folding keyboard with a single-axis double-folding design. This design is not only difficult to adapt to the storage needs of ultra-thin mobile devices, resulting in a large size of the keyboard when folded, making it inconvenient to put in a pocket or backpack for carrying, but also changes the standard layout of the keyboard when unfolded, requiring users to adapt and resulting in poor user comfort.

[0004] Integrated voice keyboards often use a 2-4 microphone linear array (such as the smart voice keyboard disclosed in the existing patent with the authorization announcement number "CN206363267U"). This keyboard has a directional sound pickup blind zone in complex sound field environments, resulting in a low signal-to-noise ratio and a significant decrease in far-field recognition rate, making it difficult to meet the user's needs in diverse scenarios.

Two sets of adjustment components are provided on the inner side of the mounting grooves, which can fix the base plates B and C after the keyboard is folded, preventing the base plates B and C from becoming loose and causing discomfort when carrying them.

[0008] Preferably, the adjustment assembly includes a magnetic block B, guide rods, and sleeves. Two sets of guide rods are located inside the mounting groove, and sleeves are fitted on the outer sides of the two sets of guide rods. The magnetic block B is fitted on the side of the two sets of sleeves that are close to each other. When the keyboard is in use, the magnetic block B can be unfolded to form a keyboard support.

[0009] Preferably, there are eight sets of microphones. Two sets of microphones are located at both ends of the base plate A, three sets of microphones are located at both ends and one side of the base plate B, and three sets of microphones are located at both ends and one side of the base plate C. The eight sets of microphones are distributed in different positions of the keyboard to form an efficient sound acquisition array, which improves the voice recognition effect.

[0010] Preferably, the bottom of the base plate A has four sets of grooves, and the iron sheet is located inside the grooves for mounting the iron sheet. After the keyboard is folded, the magnetic block B and the magnetic block A can be inserted into the grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the three-fold multi-microphone array intelligent voice input keyboard device;

[0013] 1. Through the cooperation between base plate A, base plate B, base plate C and hinge axis, the three-fold structure allows the keyboard to be easily folded when not in use, significantly reducing its size compared to traditional keyboards. This makes it convenient for users to carry around in mobile office, travel and other scenarios, greatly improving the ease of use of the keyboard. Furthermore, when unfolded, it can form a drive keyboard layout, making it more comfortable to use.

[0014] 2. Through the cooperation between the voice recognition module, microphone, and signal processing chip, the eight-microphone pickup matrix, combined with advanced voice recognition technology, greatly improves the accuracy of voice input. Whether in a quiet indoor environment or a noisy outdoor environment, it can accurately recognize the user's voice commands, effectively reduce voice recognition errors, and improve work efficiency.

[0015] At the same time, by combining a multi-microphone array with advanced speech recognition technology, the keyboard device can adapt to various complex environmental noises, ensuring stable and accurate voice input in different environments and meeting users' needs in diverse scenarios.

[0016] 3. Through the cooperation between the iron sheet, mounting groove, magnet A, magnet B, guide rod and sleeve, the keyboard can be prevented from loosening and affecting carrying comfort after folding by the magnetic attraction between the magnet and the iron sheet. When in use, by flipping magnet B, the repulsive force of the magnets can support one end of the keyboard to act as a stand. It can be adjusted according to the user's needs, thus improving the comfort of using the keyboard. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4The present invention provides an embodiment of a three-fold multi-microphone array intelligent voice input keyboard device, comprising a base plate A1, with hinge shafts 15 on both sides of the base plate A1, and base plates B2 and C6 respectively fitted on the outer sides of the two sets of hinge shafts 15. Circuit boards 3 are provided inside the base plates A1, B2 and C6, and multiple sets of keys 4 are evenly arranged on the three sets of circuit boards 3. A voice recognition module 5 and a signal processing chip 14 are provided on the right set of circuit boards 3. The voice recognition module 5 adopts iFlytek voice recognition technology. iFlytek has leading technical advantages in the field of voice recognition. Its powerful algorithm can quickly and accurately recognize and convert the voice signal collected by the 8-microphone receiving matrix, and accurately convert the voice content into text displayed on the connected electronic device.

[0024] Multiple sets of microphones 8 are installed on the outer sides of base plate A1, base plate B2 and base plate C6. There are a total of eight sets of microphones 8. Two sets of microphones 8 are located at both ends of base plate A1, three sets of microphones 8 are located at both ends and one side of base plate B2, and three sets of microphones 8 are located at both ends and one side of base plate C6. The eight sets of microphones 8 are distributed in different positions of the keyboard to form an efficient sound acquisition array, which improves the voice recognition effect. Four sets of magnetic fixing components are installed at the bottom of base plate A1.

[0025] The magnetic fixing assembly includes an iron sheet 7, a mounting groove 9, and a magnetic block A10. The iron sheet 7 is located at the bottom of the base plate A1. The bottom of the base plate A1 has four sets of grooves, and the iron sheet 7 is located inside the grooves for mounting. After the keyboard is folded, the magnetic blocks B11 and A10 can be locked into the grooves. The bottom of the base plates B2 and C6 has mounting grooves 9. The inner sides of the two sets of mounting grooves 9 and the bottom of the base plates B2 and C6 are all equipped with magnetic blocks A10. The inner side of the mounting grooves 9 is equipped with two sets of adjustment components, which can fix the base plates B2 and C6 after the keyboard is folded to prevent the base plates B2 and C6 from becoming loose and causing discomfort during carrying.

[0026] The adjustment assembly includes a magnetic block B11, guide rods 12, and sleeves 13. Two sets of guide rods 12 are located inside the mounting groove 9, and sleeves 13 are fitted on the outer sides of the two sets of guide rods 12. Damping plates are provided at the bottom of the two sets of guide rods 12 to prevent the magnetic block B11 from shaking continuously when supporting the keyboard. The magnetic block B11 is fitted on the side of the two sets of sleeves 13 that are close to each other. When the keyboard is in use, the magnetic block B11 can be unfolded to form a keyboard support.

[0027] Example:

[0028] When the device is in use, the magnetic block B11 can be rotated 180 degrees so that the like poles of magnetic block B11 and magnetic block A10 repel each other. The repulsive force can be used to push magnetic block B11 downward. At this time, magnetic block B11 can support one end of the keyboard and act as a support. Since the keyboard only bears the force of the fingers pressing the keys, and with the damping effect of the damping plate at the bottom of the guide rod 12, the keyboard will not shake when typing and can buffer the vibration of the keyboard.

[0029] Working principle: When using this keyboard, the base plates B2 and C6 can be unfolded and placed on the desktop. Eight microphones 8 are distributed in different positions on the keyboard to form an efficient sound acquisition array. Each microphone 8 can independently collect sound signals. The built-in signal processing chip 14 analyzes and integrates these signals, which can effectively improve the range and sensitivity of sound acquisition. It can accurately capture the user's voice in different environments. The voice recognition module 5 can quickly and accurately recognize and convert the voice signals collected by the eight microphones 8 into text, which is then accurately converted into text and displayed on the connected electronic device. At the same time, this technology also has good environmental adaptability and can effectively filter noise interference in noisy environments to ensure the accuracy of voice input.

[0030] When it is necessary to carry it, the base plate B2 and base plate C6 can be flipped 180 degrees and folded to the back of the base plate A1 from the hinge axis 15. At this time, the magnetic blocks B11 and A10 can be inserted into the corresponding grooves and magnetically attracted to the iron plate 7, so that the base plate B2 and base plate C6 are fixed to the base plate A1, greatly reducing the overall size of the keyboard and making it convenient to put the keyboard into a backpack pocket for carrying.
