Description

Technical Field

[0001] The present invention relates to the technical field of voice module recognition, in particular to an automatic voice recognition device assisted by an intelligent microphone. Background Art

[0002] A speech collection recognizer, also known as a speech recognition module, is a device that can convert sound into electrical signals. It is usually composed of components such as a membrane, a conductor, and a magnet. It uses the vibration of the acoustic pressure membrane to generate current, thereby converting sound. Speech collection recognizers can be divided into two categories: dynamic speech recognition modules and condenser speech recognition modules. The dynamic speech recognition module uses the principle of electromagnetic induction to generate current through the vibration of the acoustic pressure membrane, while the condenser speech recognition module uses the principle of capacitive induction to generate current through changes between the acoustic pressure membrane and the backplate.

[0003] However, when existing voice recognition devices are used in office meetings for a long time, dust will accumulate in the sound receiving area of ​​the voice recognition device due to long-term use. When voice recognition devices are not used for a long time, especially those placed in an open environment, dust in the air will adhere to the voice recognition module, causing dust and other particles to accumulate on the surface of the voice recognition module. This dust will affect the collection and transmission of the voice recognition device, reducing the sound quality and sensitivity of the voice recognition device, resulting in a decline in sound reception effect.

[0004] In addition, when using existing conference and office voice collection and recognition devices, landline voice collection and recognition devices are usually designed to receive sound in a specific direction, which means that only the sound directly in front of the voice collection and recognition device can be effectively captured. If the speaker deviates from this optimal receiving area, the clarity and volume of the sound may drop significantly. At the same time, because the height of the landline voice collection and recognition device is fixed and cannot adapt to users of different heights, this will not only cause the user to bend over or stretch their neck to adapt to the position of the voice collection and recognition device, but also cause discomfort or fatigue to the user after long-term use, affecting the use effect.

[0005] Therefore, an intelligent microphone-assisted automatic speech recognition device is proposed to solve the above problems. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose an automatic speech recognition device assisted by an intelligent microphone to solve the problems in the prior art that the speech collection and recognition device is cumbersome to use and the speech collection and recognition device is prone to dust accumulation.

[0008] The height adjustment mechanism is used to adjust the height of the voice recognition module;

[0009] The angle adjustment mechanism is used to adjust the angle of the voice recognition module;

[0010] The protection mechanism is used to protect the surface of the voice recognition module from dust and to automatically protect the voice recognition module before and after use.

[0011] As an improvement, the height adjustment mechanism includes an adjustment handle, the fixed cylinder is fixedly connected to a protective chamber on one side close to the adjustment handle, the adjustment handle is rotatably connected to the protective chamber, and the adjustment handle is fixedly connected to a worm on one end close to the inner wall of the protective chamber.

[0012] As an improvement, the worm tooth surface is meshed with a turbine, a connecting shaft is fixedly connected to the middle of the turbine, the outer surface of the connecting shaft is rotatably connected to the protective bin, and an engaging gear is fixedly connected to the end of the connecting shaft away from the turbine.

[0013] As an improvement, the fixing cylinder is provided with an engagement groove on the side close to the meshing gear, and the sliding rod is evenly provided with sliding tooth grooves on the side close to the meshing gear, and the tooth surface of the meshing gear passes through the engagement groove and meshes with the sliding tooth groove.

[0014] As an improvement, the angle adjustment mechanism includes a bracket, which is symmetrically fixedly connected to the slide rod, a pressing block is provided in the middle of one side of the bracket, and an adjustment plate is provided on the side of the bracket away from the pressing block.

[0015] As an improvement, the pressing block is rotatably connected to the adjustment plate, and the adjustment plate is fixedly connected with an engaging tooth on the side away from the pressing block. An engaging tooth groove is opened in the middle of the side of the bracket close to the engaging tooth, and the tooth surface of the engaging tooth is engaged in the engaging tooth groove.

[0016] As an improvement, the engaging tooth is rotatably connected to a guide plate on the side away from the adjustment plate, and the guide plate is fixedly connected to a return spring on the side away from the engaging tooth. The return spring is fixedly connected to a fixed shell on one end away from the guide plate, and the fixed shell is fixedly connected to the bracket on the side of the slide rod close to the engaging tooth, and the outer surface of the guide plate is slidably connected to the inner wall of the fixed shell.

[0017] As an improvement, the protective mechanism includes a slide, the bottom of the slide is slidably connected to the voice recognition module, a telescopic cylinder is installed on the voice recognition module, one end of the slide is fixedly connected to the drive shaft of the telescopic cylinder, and the other end of the slide is fixedly connected to a double-sided sliding rack, the bottom of the double-sided sliding rack is slidably connected to the voice recognition module, the tooth surface of the double-sided sliding rack is meshed with rotating teeth, the middle part of the rotating teeth is fixedly connected to the transmission shaft, and the protective cover is fixedly connected to the upper end of the transmission shaft.

[0018] Compared with the prior art, the present invention provides an intelligent microphone-assisted automatic speech recognition device, which has the following beneficial effects:

[0020] 2.

Compared with the existing telescopic rod, the bracket can be quickly adjusted and locked by manually adjusting the handle. This not only makes the voice collection recognizer adapt to users of different heights, allowing them to talk in a comfortable posture, but also reduces the existing need to manually and frequently turn the screws to adjust the bracket height, further improving the user efficiency.

[0021] 3. Through the setting of the protection mechanism and the angle adjustment mechanism, not only can the operator reduce the torque unevenness or tightness problems when manually tightening the nut, but also the accidents caused by over-tightening or loosening, especially for some occasions that require precise control of force, further reduce the damage to the voice recognition module caused by excessive force during fine-tuning of the electronic equipment. The voice recognition module that can be pressed to automatically adjust the angle can also make the voice collection recognizer more flexible to use. The user can quickly adjust the angle of the voice collection recognizer as needed, which is not only convenient to operate, but also avoids the torque unevenness or tightness problems when the thread is tightened, thereby adapting to different usage scenarios.

All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the scope of protection of the present invention.

[0035] The present invention will be further described in detail below based on the accompanying drawings and examples;

[0036] Example

[0037] Please refer to Figures 1 to 7 As shown:

[0038] To solve the problems mentioned in the technical solution, the embodiment of the present application provides an automated speech recognition device assisted by an intelligent microphone, including a support 1, a fixed cylinder 101 fixedly connected to the middle of the upper surface of the support 1, a sliding rod 102 slidably connected to the inner wall of the fixed cylinder 101, a speech recognition module 103 is provided at the upper end of the sliding rod 102, and protective covers 104 are symmetrically provided on both sides of the speech recognition module 103. The automated speech recognition device assisted by an intelligent microphone includes a height adjustment mechanism 2, an angle adjustment mechanism 3 and a protective mechanism 4, the height adjustment mechanism 2 is provided on the fixed cylinder 101, the angle adjustment mechanism 3 is provided on the upper end of the sliding rod 102, and the protective mechanism 4 is provided on the speech recognition module 103;

[0039] The height adjustment mechanism 2 is used to adjust the height of the voice recognition module 103;

[0040] The height adjustment mechanism 2 includes an adjustment handle 201. A protective chamber 203 is fixedly connected to the fixed cylinder 101 near the adjustment handle 201. The adjustment handle 201 is rotatably connected to the protective chamber 203. A worm 202 is fixedly connected to the end of the adjustment handle 201 near the inner wall of the protective chamber 203.

[0041] The tooth surface of the worm 202 is meshed with a turbine 204. A connecting shaft 205 is fixedly connected to the middle of the turbine 204. The outer surface of the connecting shaft 205 is rotatably connected to the protective chamber 203. The end of the connecting shaft 205 away from the turbine 204 is fixedly connected to a meshing gear 206.

[0042] A meshing groove is formed on the side of the fixed cylinder 101 close to the meshing gear 206, and sliding tooth grooves 207 are evenly formed on the side of the sliding rod 102 close to the meshing gear 206. The tooth surface of the meshing gear 206 passes through the meshing groove and meshes with the sliding tooth groove 207.

[0043] Among them: the bracket 301 is symmetrically arranged on the upper end of the slide bar 102, such as Figure 6 As shown, an engaging tooth groove 305 is formed in the middle of the left bracket 301 .

[0044] In the prior art, when the existing voice collection and recognition device is used in office meetings for a long time, dust will accumulate in the sound receiving area of ​​the voice collection and recognition device due to long-term use. When the voice collection and recognition device is not used for a long time, especially those placed in an open environment, dust in the air will adhere to the voice recognition module 103, causing dust and other particles to accumulate on the surface of the voice recognition module 103. These dust particles will affect the collection and transmission of the sound of the voice collection and recognition device, reduce the sound quality and sensitivity of the voice collection and recognition device, and lead to a decrease in the sound reception effect. Compared with the prior art, through the implementation of this embodiment, the height-adjustable support frame can not only make the voice collection and recognition device adapt to users of different heights, so that they can make calls in a comfortable posture, which is conducive to reducing neck fatigue and discomfort during use, but also make the voice collection and recognition device better positioned near the speaker's lips. Positioning the voice collection and recognition device near the lips can reduce the chance of receiving background noise, thereby improving the capture rate and clarity of the sound.

[0045] For further examples, please refer to Figures 1 to 7 As shown:

[0046] The angle adjustment mechanism 3 is used for adjusting the angle of the voice recognition module 103;

[0047] The protection mechanism 4 is used to protect the surface of the voice recognition module 103 from dust and automatically protect the voice recognition module 103 before and after use;

[0048] The angle adjustment mechanism 3 includes a bracket 301, which is symmetrically fixed to the slide bar 102. A pressing block 302 is provided in the middle of one side of the bracket 301, and an adjustment plate 303 is provided on the side of the bracket 301 away from the pressing block 302.

[0049] The pressing block 302 is rotatably connected to the adjusting plate 303. The adjusting plate 303 is fixedly connected to an engaging tooth 304 on a side away from the pressing block 302. An engaging tooth groove 305 is formed in the middle of the side of the bracket 301 close to the engaging tooth 304. The tooth surface of the engaging tooth 304 is engaged with the engaging tooth groove 305.

[0050] The engaging teeth 304 are rotatably connected to a guide plate 306 on the side away from the adjustment plate 303. The guide plate 306 is fixedly connected to a return spring 307 on the side away from the engaging teeth 304. The return spring 307 is fixedly connected to a fixed housing 308 on the end away from the guide plate 306. The fixed housing 308 is fixedly connected to the bracket 301 on the side of the slide bar 102 close to the engaging teeth 304. The outer surface of the guide plate 306 is slidably connected to the inner wall of the fixed housing 308.

[0051] The protection mechanism 4 includes a slide plate 401, the bottom of the slide plate 401 is slidably connected to the voice recognition module 103, a telescopic cylinder is installed on the voice recognition module 103, one end of the slide plate 401 is fixedly connected to the drive shaft of the telescopic cylinder, and the other end of the slide plate 401 is fixedly connected to a double-sided sliding rack 402, the bottom of the double-sided sliding rack 402 is slidably connected to the voice recognition module 103, the tooth surface of the double-sided sliding rack 402 is meshed with a rotating tooth 403, the middle of the rotating tooth 403 is fixedly connected to a transmission shaft 404, and the protective cover 104 is fixedly connected to the upper end of the transmission shaft 404;

[0052] Among them: because the power supply of the voice recognition module 103 is electrically connected to the telescopic cylinder installed on the voice recognition module 103, when the voice recognition module 103 is started by the power system, the electrical signal of the voice recognition module 103 is transmitted to the controller, and the controller controls the telescopic cylinder drive shaft to start extending, and the rotating gear 403 and the transmission shaft 404 are symmetrically arranged on both sides of the voice recognition module 103.

[0053] In the prior art, when the existing conference office voice collection and recognition devices are in use, the landline voice collection and recognition devices are usually designed to face a specific direction to receive sound, which means that only the sound directly in front of the voice collection and recognition device can be effectively captured. If the speaker deviates from this optimal receiving area, the clarity and volume of the sound may be significantly reduced. At the same time, because the height of the landline voice collection and recognition device is fixed and cannot adapt to users of different heights, this not only causes the user to bend over or stretch their neck to adapt to the position of the voice collection and recognition device, but also causes discomfort or fatigue to the user when using it for a long time, affecting the use effect. Compared with the prior art, through the implementation of this embodiment, it is possible to prevent The protective cover 104 can effectively protect the voice collection and recognition device from the influence of dust, oil and other dirt in the air, and prevent the dust in the air from adhering to the voice collection and recognition device when the voice collection and recognition device is not used for a long time, making the signal reception of the voice collection and recognition device unstable when in use, and can prevent external noise from interfering with calls. At the same time, compared with the landline-type voice collection and recognition device in the prior art, if the user accidentally bumps into the voice collection and recognition device after the use of the voice collection and recognition device, causing it to slide, fall and fall, the protective mechanism 4 can effectively protect the voice collection and recognition device from the influence of factors such as dirt and scratches, thereby extending the service life of the voice collection and recognition device.

[0054] Everything in the above example works as follows:

[0055] In the initial state, the return spring 307 is not compressed, the engaging teeth 304 and the engaging tooth grooves 305 are engaged with each other, and the telescopic cylinder is contracted.

[0056] The following is a working process of the height adjustment mechanism 2 for adjusting the height of the voice recognition module 103:

[0057] When the user needs to start the voice recognition device in the office or meeting, when the user needs to adjust the height of the voice recognition module 103 when using the voice recognition module 103, the user manually rotates the handle 201, such as Figure 4 As shown, since the adjusting handle 201 is rotatably connected to the protective chamber 203 and fixed to the middle of the worm 202, the user manually rotates the adjusting handle 201 to drive the worm 202 to start rotating in the same direction, and since the tooth surface of the worm 202 is meshed with the turbine 204, the rotation of the worm 202 causes the turbine 204 to start rotating in the opposite direction. At this time, since the middle of the turbine 204 is fixedly connected to the connecting shaft 205, and the outer surface of the connecting shaft 205 rotates on the protective chamber 203, the connecting shaft 205 is away from the turbine 204. 04 is fixed to one end of the meshing gear 206, and because the fixing cylinder 101 is provided with a meshing groove at one end thereof near the meshing gear 206, the meshing gear 206 meshes with the sliding tooth groove 207 provided on the slide bar 102 through the meshing groove. At this time, the reverse rotation of the turbine 204 drives the sliding tooth groove 207 to start moving, so that when the adjusting handle 201 rotates clockwise, the worm 202 drives the turbine 204 to start rotating counterclockwise, and the counterclockwise rotation of the turbine 204 drives the connecting shaft 20 5 drives the meshing gear 206 to make the slide bar 102 start to slide upward on the inner wall of the fixed cylinder 101; similarly, when the adjusting handle 201 rotates counterclockwise, the worm 202 drives the turbine 204 to start rotating clockwise, and the turbine 204 rotates clockwise, which drives the connecting shaft 205 to drive the meshing gear 206 to make the slide bar 102 start to slide downward on the inner wall of the fixed cylinder 101. Compared with the existing method of manually adjusting the height of the bracket by the operator turning the screw, it is necessary to manually tighten the bracket again. The height-adjustable support frame provided with the height-adjusting mechanism 2 only needs to manually adjust and lock the bracket by the operator to achieve the purpose of adjusting the height of the bracket by turning the adjusting handle 201. Compared with the existing telescopic rod, the bracket can be quickly adjusted and locked by manually turning the adjusting handle 201. This not only makes the voice collection and recognition device adaptable to users of different heights, allowing them to talk in a comfortable posture, but also reduces the need to manually turn the screw frequently to adjust the height of the bracket, thereby further improving the user's efficiency.

[0058] Please refer to the above working process Figures 1 to 7 .

[0059] The following is the working process of the angle adjustment mechanism 3 for adjusting the angle of the voice recognition module 103:

[0060] When the height adjustment mechanism 2 adjusts the height of the voice recognition module 103 to adapt to the voice reception of the voice recognition module 103, the voice recognition efficiency can be improved by adjusting the angle between the voice recognition module 103 and the user's speech. Figure 6 As shown, the left fixed shell 308 and the right pressing block 302 are pressed simultaneously. Since the fixed shell 308 is fixedly connected to the left bracket 301 of the slide bar 102, and the pressing block 302 slides in the middle of the right bracket 301, the pressing of the pressing block 302 will drive the adjustment plate 303 to start sliding to the left, and the sliding of the adjustment plate 303 to the left will drive the meshing teeth 304 that were initially engaged with the meshing tooth groove 305 to gradually disengage. At the same time, the sliding of the meshing teeth 304 to the left will cause the guide plate 306 to start sliding to the left in the fixed shell 308. The guide plate 306 slides on the inner wall of the fixed shell 308 to make the meshing tooth groove 305 disengage from the meshing tooth groove 305 and make it more stable after sliding. At this time, the return spring 307 begins to be compressed when the guide plate 306 slides to the left. At this time, the user only needs to manually adjust the angle of the voice recognition module 103. When the voice recognition module 103 is adjusted to the optimal angle, the user only needs to release the pressing block 302. At this time, the return spring 307 drives the guide plate 306 to slide to the right in the fixed shell 308 under the elastic action of the return spring 307. The angle adjustment mechanism 3 is provided so that the angle of the voice collection recognition device can be adjusted by manually pressing, and the user can make calls in a comfortable posture. Compared with the existing method of manually rotating the screw to adjust the angle of the voice collection recognition device, the angle adjustment mechanism 3 is provided. It can not only reduce the torque unevenness or looseness problems caused by the operator when manually tightening the nut, but also reduce accidents caused by over-tightening or loosening, especially for some occasions that require precise control of force. It further reduces the damage to the voice recognition module 103 caused by excessive force during fine-tuning of electronic equipment. The voice recognition module 103 that can be pressed to automatically adjust the angle can also make the voice collection recognition device more flexible in use. The user can quickly adjust the angle of the voice collection recognition device as needed, which is not only convenient to operate, but also avoids the torque unevenness or looseness problems caused by screwing, thereby adapting to different usage scenarios.

[0061] When the operator uses the voice recognition module 103, because the power supply of the voice recognition module 103 is electrically connected to the telescopic cylinder installed on the voice recognition module 103, when the voice recognition module 103 is started by the power system, the electrical signal of the voice recognition module 103 is transmitted to the controller, and the controller controls the telescopic cylinder drive shaft to start extending. Figure 7 As shown, because one end of the slide 401 is fixed to the telescopic cylinder drive shaft, the other end is fixed to the double-sided sliding rack 402, and the bottom of the slide 401 slides on the voice recognition module 103, when the slide 401 is as shown Figure 7 When the double-sided sliding rack 402 slides to the left, the sliding plate 401 will drive the double-sided sliding rack 402 to start sliding to the left. Because the sliding tooth surfaces on both sides of the double-sided sliding rack 402 are meshed with the rotating gear 403, and the rotating gear 403 is symmetrically arranged on both sides of the double-sided sliding rack 402, the sliding of the double-sided sliding rack 402 to the left will cause the rotating gear 403 above the double-sided sliding rack 402 to drive the transmission shaft 404 to start rotating clockwise, thereby driving the protective cover 104 to start opening clockwise, and the sliding of the double-sided sliding rack 402 to the left will cause the rotating gear 403 below the double-sided sliding rack 402 to drive the transmission shaft 404 to start rotating counterclockwise, thereby driving the protective cover 104 to start opening counterclockwise, thereby causing the voice recognition module 103 to automatically open the protective cover 104 when it is started. When the voice recognition module 103 is used and the user turns off the power of the voice recognition module 103, the telescopic cylinder will begin to retract. At this time, the protective cover 104 will be driven to close in the voice recognition state by the sliding plate 401. On the identification module 103, through the setting of the protective mechanism 4, the protective cover 104 can effectively protect the voice collection and recognition device from the influence of dust, oil and other dirt in the air, and prevent the dust in the air from adhering to the voice collection and recognition device when the voice collection and recognition device is not used for a long time, making the signal reception of the voice collection and recognition device unstable when in use, and can prevent external noise from interfering with the call. At the same time, compared with the landline-type voice collection and recognition device in the prior art, if the user accidentally bumps into the voice collection and recognition device after the use of the voice collection and recognition device, causing it to slide, fall and fall, the setting of the protective mechanism 4 can effectively protect the voice collection and recognition device from factors such as dirt and scratches, thereby extending the service life of the voice collection and recognition device, and there is no need to manually put the protective cover 104 on the voice collection and recognition device, which is more convenient to use. Compared with the existing method, it can prevent the protective cover 104 from being easily lost, and when in use, the protective cover 104 can be directly opened without affecting the normal use of the voice collection and recognition device.
