Description

Technical Field

[0001] This utility model relates to the field of speech transcription technology, and more specifically, to an offline speech transcription device for an intelligent scheduling system. Background Technology

[0002] With the rapid development of artificial intelligence and speech recognition technologies, speech-to-text (STT) has become an important application in the field of natural language processing (NLP). Traditional speech-to-text services typically rely on cloud computing, such as Google Speech-to-Text and Microsoft Azure Speech, which require an internet connection and suffer from issues such as latency, privacy breaches, and network dependency. In recent years, on-device AI technology has emerged, and localized speech recognition devices have been increasingly used for organizing and recording meeting minutes.

[0003] However, existing offline speech transcription devices have poor stability. They are usually fixed with simple brackets or magnetic attachments, which are prone to displacement or falling off when the desktop vibrates, moves, or is slightly touched. This causes the microphone to deviate from the sound source, reducing the accuracy of sound pickup. Poor stability not only affects the core functions of offline speech transcription devices (sound pickup and transcription accuracy), but also reduces user experience and scene adaptability.

[0004] Therefore, there is an urgent need for an offline speech transcription device for intelligent scheduling systems to solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, the present invention proposes an offline speech transcription device for intelligent scheduling systems, aiming to solve the problem of poor stability of existing speech transcription devices.

[0006] This utility model provides a voice offline transcription device for an intelligent scheduling system, comprising:

[0007] The housing has a locking groove on its outer surface;

[0008] A locking mechanism is engaged with the housing via a locking groove for a locking connection.

[0009] The voice mechanism is fixedly connected to the locking mechanism;

[0010] The pickup mechanism is housed within the housing;

[0011] The adsorption mechanism is fixedly connected to the lower surface of the housing.

[0012] Furthermore, a first groove is formed on the inner wall of the locking groove. The first groove is a semi-circular groove. A second groove is formed on the right side of the first groove. A locking block is provided in the second groove. A torsion spring is provided between the locking block and the bottom wall of the second groove. The torsion spring is fixedly connected to the locking block and the second groove respectively.

[0013] Furthermore, the locking mechanism includes a locking post, a locking cone, locking beads, a locking ring, and a sealing ring. The sealing ring is sleeved on one side of the locking post and is fixedly connected to the locking post. The other side of the locking post is fixedly connected to the locking cone. The outer surface of the locking cone is provided with locking beads, and the locking beads are arranged one-to-one with the first groove. A plurality of locking rings are arranged between the locking cone and the sealing ring, and a locking groove is formed between the plurality of locking rings. The size of the locking groove corresponds to the locking block.

[0014] Furthermore, the adsorption mechanism includes a suction cup and a vacuum mechanism. The suction cup is connected to the vacuum mechanism through a guide tube, and a shock-absorbing mechanism is also provided between the vacuum mechanism and the housing.

[0015] Furthermore, the vacuum mechanism includes a switching valve and a vacuum generator, the vacuum generator being connected to the switching valve for introducing negative pressure into the suction cup or blocking negative pressure from entering the suction cup.

[0016] Furthermore, the switching valve includes a valve body and a pressing handle. The valve body has a negative pressure inlet, a negative pressure outlet, and an exhaust port that are interconnected. The negative pressure inlet is connected to the vacuum generator, and the negative pressure outlet is connected to the suction cup. The pressing handle is movably sleeved with the valve body and can move along its own axis. The pressing handle can selectively connect the negative pressure inlet to the negative pressure outlet or the negative pressure inlet to the exhaust port.

[0017] Furthermore, the voice mechanism includes a microphone body and a long gooseneck tube, one end of which is fixedly connected to the microphone body, and the other end of which is fixedly connected to the sealing ring.

[0018] Furthermore, the shock-absorbing mechanism includes a support part and a shock-absorbing part. The support part includes a bottom frame plate and reinforcing columns. The bottom frame plate is fixedly connected to the lower surface of the shell. Reinforcing columns are respectively provided at the four corners of the bottom frame plate. Shock-absorbing parts are provided between the bottom frame plates, and shock-absorbing parts are provided inside each of the reinforcing columns.

[0019] Furthermore, the shock-absorbing part includes a connecting column, a sliding plate, a torsion spring, a sliding groove, and a limiting plate. The sliding groove is disposed inside the reinforcing column, and the sliding plate is vertically slidably connected inside the sliding groove. A torsion spring is disposed between the lower surface of the sliding plate and the bottom wall of the sliding groove, and a connecting column is disposed on the upper surface of the sliding plate. The upper end of the connecting column passes through the reinforcing column and is fixedly connected to the lower surface of the bottom frame plate.

[0020] Furthermore, the pickup mechanism includes a microphone and a through hole, and the outer surface of the housing has a through hole, with the microphone located inside the through hole.

[0021] Compared with existing technologies, the advantages of this utility model are as follows: This utility model achieves a rigid connection between the housing and external components through the cooperation of the locking groove and the locking mechanism, avoiding displacement problems caused by vibration or external force in traditional adsorption or clamping methods. This improves the stability of the device in complex environments. The adsorption mechanism at the bottom of the housing can adapt to different material surfaces (such as metal, glass, and plastic), providing reliable fixation in vehicle-mounted and industrial equipment scenarios, reducing the risk of functional interruption caused by device detachment. Simultaneously, the locking mechanism reduces wear and tear on the structure from repeated disassembly and assembly, extending service life. The physical locking method avoids the loosening defects of pure magnetic or adhesive solutions after long-term use, improving the device's stability in continuous operation. To ensure reliability in various working scenarios, the built-in layout of the pickup mechanism integrates the pickup module into the housing. The housing structure shields some external electromagnetic interference and reduces microphone angle shift caused by device displacement, ensuring the stability of the sound source direction and thus improving the clarity of voice signal acquisition. Furthermore, the rigid connection between the housing and the locking mechanism reduces mechanical noise caused by vibration. Combined with the shock absorption effect of the adsorption mechanism, it suppresses background noise interference on the voice signal in noisy environments. The direct fixing design between the voice mechanism and the locking mechanism avoids the problem of loose or broken connecting cables in traditional split structures, ensuring the signal transmission stability between the voice processing module and the pickup module and reducing the probability of transcription interruption.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] See Figure 1 As shown, this embodiment provides a voice offline transcription device for an intelligent scheduling system, including: a housing 1, wherein a locking groove 2 is provided on the outer surface of the housing 1;

[0033] The locking mechanism 3 is locked to the housing 1 through the locking groove 2;

[0034] The voice mechanism 4 is fixedly connected to the locking mechanism 3;

[0035] The pickup mechanism 6 is disposed inside the housing 1;

[0036] The adsorption mechanism 8 is fixedly connected to the lower surface of the housing 1.

[0037] Specifically, a locking groove 2 is provided on one side of the housing 1. The voice mechanism 4 is fixedly connected to the locking mechanism 3. The voice mechanism 4 is locked by the locking mechanism 3 and the locking groove 2. A pickup mechanism 6 is provided in the middle of the housing 1 on one side of the locking groove 2 for receiving voice data. The adsorption mechanism 8 is located at the bottom of the housing 1 and the housing 1 can be kept stable by negative pressure adsorption.

[0038] Understandably, the rigid fit between the locking groove 2 and the locking mechanism 3 mechanically secures the voice mechanism 4 to the housing 1, avoiding the loosening issues caused by vibration or collisions in traditional snap-fit ​​or magnetic structures. This ensures the device remains stable in dynamic environments (such as vehicle bumps or industrial vibrations). The negative pressure fixation of the adsorption mechanism 8, located at the bottom of the housing 1, adheres to the contact surface through the negative pressure principle, forming strong adhesion on smooth materials (such as glass or metal), reducing the risk of displacement or tipping due to external interference. The dual fixation of the locking mechanism 3 and the adsorption mechanism 8 suppresses the impact of external vibration or impact on the device's posture, reduces mechanical noise caused by device shaking, and prevents sound source deviation due to displacement of the pickup module. The integrated structure of the housing 1 and the locking groove 2 reduces exposed connection gaps, preventing dust or liquid from entering the internal circuitry and improving durability in harsh environments (such as humid or dusty environments).

[0039] In some embodiments of this application, see Figure 2As shown, the inner wall of the locking groove 2 is provided with a first groove 201, which is a semi-circular groove. A second groove 202 is provided on the right side of the first groove 201. A locking block 203 is provided in the second groove 202. A torsion spring 7 is provided between the locking block 203 and the bottom wall of the second groove 202. The torsion spring 7 is fixedly connected to the locking block 203 and the second groove 202 respectively.

[0040] Specifically, the first groove 201 is located at the inner end of the locking groove 2. The first groove 201 is semi-circular in shape and is used to cooperate with the locking mechanism 3 to achieve locking. At the same time, the locking block 203 in the second groove 202 is displaced by the torsion spring 7 and is used to cooperate with the locking mechanism 3 to achieve further locking. Since the locking block 203 is trapezoidal in shape, when the locking mechanism 3 moves inward, it will drive the locking block 203 to move into the second groove 202. When it moves to a certain distance, the locking block 203 rebounds, achieving the locking effect.

[0041] Understandably, the geometric structure of the semi-circular first groove 201 provides a precise guiding path for the locking mechanism 3, ensuring that the locking component fully fits against the groove wall during insertion, increasing the contact area, thereby improving the tensile strength and torsional resistance of the mechanical connection.

[0042] The dynamic locking of the trapezoidal locking block 203 involves the trapezoidal inclined surface of the locking block 203 contacting the locking mechanism 3. This inclined surface guides the locking mechanism 3 towards the interior of the second groove 202. Combined with the elastic rebound force of the torsion spring 7, a self-locking effect is formed, preventing accidental loosening due to external vibration or impact. The elastic return characteristic of the torsion spring 7 allows the locking block 203 to automatically complete the continuous "guide, lock, and fix" action when the locking mechanism 3 is inserted, eliminating the need for manual adjustment of the locking force and simplifying the operation. The trapezoidal structure of the locking block 203 allows for rapid separation by applying reverse force during unlocking, avoiding the wear accumulation problems caused by repeated disassembly and assembly of traditional screw or snap-fit ​​structures. The torsion spring 7 forms an elastic connection between the locking block 203 and the locking mechanism 3, absorbing external vibration energy and reducing the impact of mechanical impact on locking stability. The arc-shaped inner wall of the first groove 201 evenly distributes the force on the locking mechanism 3 to the housing 1, preventing localized deformation or cracking caused by stress concentration and enhancing the structural reliability for long-term use.

[0043] In some embodiments of this application, see Figure 3As shown, the locking mechanism 3 includes a locking pin 301, a locking cone 302, a locking bead 303, a locking ring 304, and a sealing ring 305. The sealing ring 305 is sleeved on one side of the locking pin 301 and is fixedly connected to the locking pin 301. The other side of the locking pin 301 is fixedly connected to the locking cone 302. The outer surface of the locking cone 302 is provided with locking beads 303, and the locking beads 303 are provided in a one-to-one correspondence with the first groove 201. A plurality of locking rings 304 are provided between the locking cone 302 and the sealing ring 305, and a locking groove 306 is formed between the plurality of locking rings 304. The size of the locking groove 306 corresponds to the locking block 203.

[0044] Specifically, the locking post 301 is the central support post, and a tapered locking cone 302 is provided on one side of the locking ball 303. The surface of the locking cone 302 is provided with the locking ball 303. The locking ball 303 can retract and rebound into the locking cone 302. That is, when the locking ball 303 moves into the locking groove 2, the locking ball 303 rebounds into the locking cone 302 under the action of the inner wall of the locking groove 2, without affecting the displacement of the locking post 301. When it moves to the corresponding position of the first groove 201, since the shape of the locking ball 303 corresponds to the first groove 201, the locking ball 303 rebounds into the first groove 201, that is, half of the locking ball 303 is located in the first groove 201. The locking block 203 fits into the first groove 201, with half of it located inside the locking cone 302. Several locking rings 304 are provided in the middle of the locking pin 301, forming a locking groove 306 between the locking rings 304. When the locking pin 301 moves to the corresponding position of the second groove 202, the locking block 203 rebounds downward into the locking groove 306 to achieve the locking effect. The sealing ring 305 is on the other side of the locking pin 301. When the locking pin 301 is completely moved into the locking groove 2, the sealing ring 305 is used to seal the gap between the locking groove 2 and the locking pin 301. A sealing sleeve can also be fitted between the sealing ring 305 and the locking pin 301 for further sealing and to improve the sealing performance.

[0045] It is understandable that the dynamic engagement of the locking ball 303 with the first groove 201 utilizes the elastic retraction and springback characteristics of the locking ball 303 on the surface of the locking cone 302, allowing it to automatically adapt to the inner wall of the groove when the locking pin 301 is inserted into the locking groove 2. When the locking ball 303 is aligned with the first groove 201, it partially embeds into the groove to form initial fixation, achieving precise positioning and anti-pull-out capability. The secondary locking of the locking ring 304 and the locking block 203 is achieved when the locking pin 301 is displaced to the second groove 202, and the locking block 203 embeds into the groove between the locking ring 304, forming a double lock through mechanical engagement. This suppresses axial displacement caused by vibration or external force, improving the overall torsional and impact resistance. The adaptive springback structure of the locking ball 303 can compensate for the dimensional tolerances or safety features between the locking groove 2 and the locking pin 301. The installation angle deviation ensures stable connection under high temperature, low temperature or vibration scenarios. The conical structure of the locking cone 302 guides the locking ball 303 to distribute pressure evenly along the force direction, avoiding deformation or wear of parts caused by local stress concentration. At the same time, the electrical connection of the voice mechanism 4 is formed with the locking groove 2 through the top of the cone. The sealing ring 305 and the locking column 301 work together to seal the locking mechanism 301. The sealing ring 305 is tightly attached to the inner wall of the locking groove 2, preventing external dust and liquid from entering the locking mechanism 3. With the optional sealing sleeve, a multi-layer protective barrier is formed, which enhances the durability of the equipment in humid and dusty environments. After the locking column 301 is fully inserted, the sealing ring 305 fills the gap between the housing 1 and the locking column 301, avoiding mechanical jamming or circuit failure caused by the accumulation of foreign objects due to long-term use.

[0046] In some embodiments of this application, see Figure 4 As shown, the adsorption mechanism 8 includes a suction cup 801 and a vacuum mechanism. The suction cup 801 is connected to the vacuum mechanism through a guide tube. A shock-absorbing mechanism 5 is also provided between the vacuum mechanism and the housing 1.

[0047] In some embodiments of this application, the vacuum mechanism includes a switching valve and a vacuum generator 803, wherein the vacuum generator 803 is connected to the switching valve for introducing negative pressure into the suction cup 801 or blocking the introduction of negative pressure into the suction cup 801.

[0048] Specifically, the suction cup 801 is located at the bottom and is used to adsorb objects such as desktops. The vacuum generator 803 is controlled by a switch valve, and then the vacuum is applied to the suction cup 801 through the guide tube to achieve the adsorption effect.

[0049] Understandably, the dynamic adjustment of vacuum negative pressure actively regulates the negative pressure intensity within the suction cup 801 through the vacuum generator 803, adapting to the adsorption needs of different material surfaces (such as glass, metal, and rough tabletops). This avoids the accidental detachment of the traditional suction cup 801 due to uneven air pressure. The vibration isolation of the damping mechanism 5 absorbs and disperses external vibration energy (such as vehicle bumps and industrial equipment vibrations), reducing the impact of mechanical shock on adsorption stability and ensuring the equipment remains stable in dynamic environments. The active negative pressure generation mechanism of the vacuum generator 803 can compensate for minor surface bumps or gaps, improving the adaptability to non-ideal contact surfaces and reducing the risk of adsorption failure due to uneven surfaces. The vacuum generator 803 is quickly opened and closed via a switching valve, enabling instant adsorption and release of the suction cup 801. This avoids the cumbersome operation of manually pressing to expel air, as required by traditional mechanical suction cups 801, improving deployment efficiency. Furthermore, adsorption fixation does not require drilling, gluing, or reliance on magnetic surfaces, protecting the integrity of the installation surface. This is especially suitable for temporary meetings, rental venues, or high-end furniture environments.

[0050] In some embodiments of this application, the switching valve includes a valve body 802 and a pressing handle 804. The valve body 802 is provided with a negative pressure inlet 805, a negative pressure outlet 806, and an exhaust port 807 that are interconnected. The negative pressure inlet 805 is connected to the vacuum generator 803, and the negative pressure outlet 806 is connected to the suction cup 801. The pressing handle 804 is movably sleeved with the valve body 802 and can move along its own axis. The pressing handle 804 can selectively connect the negative pressure inlet 805 to the negative pressure outlet 806 or the negative pressure inlet 805 to the exhaust port 807.

[0051] Understandably, the axial displacement control of the pressing handle 804 directly switches the connection state between the negative pressure inlet 805 and the outlet or exhaust port 807 by moving the pressing handle 804 along the axial direction, realizing the rapid switching of adsorption and release functions, reducing the time cost of traditional knob or multi-step operation. The isolation of the unidirectional flow channel is achieved through the independent channel layout of the negative pressure inlet 805, outlet and exhaust port 807, avoiding gas backflow or cross-contamination, ensuring that the negative pressure output by the vacuum generator 803 is stably transmitted to the suction cup 801, improving the response speed and consistency of the adsorption force. The linear movement of the pressing handle 804 conforms to ergonomic intuition, and users can complete adsorption and release with simple push and pull actions without learning complex operating logic, which is especially suitable for emergency scenarios or non-professionals.

[0052] In some embodiments of this application, the voice mechanism 4 includes a microphone body 401 and a long gooseneck tube 402, one end of which is fixedly connected to the microphone body 401, and the other end of which is fixedly connected to the sealing ring 305.

[0053] Understandably, the free-bending nature of the long gooseneck tube 402 allows users to manually adjust the bending angle and length of the gooseneck tube to position the microphone body 401 in the optimal pickup position (such as near the speaker's mouth or away from ambient noise sources), ensuring clear speech signals and reducing the degradation of pickup quality caused by fixed position deviations. The flexible structure of the gooseneck tube allows the microphone to bypass obstacles (such as laptops and desktop devices) or adapt to narrow spaces (such as car dashboards and medical operating tables), expanding the application potential of the device in complex scenarios. It eliminates the need for fixed brackets or external extension cables, and the self-supporting characteristics of the gooseneck tube enable the microphone to float and position itself, avoiding pickup blind spots caused by insufficient desktop space or device obstruction. The rigid connection between the sealing ring 305 and the locking mechanism 3 ensures that the gooseneck tube remains stable after adjustment, preventing microphone displacement due to gravity or slight touch.

[0054] In some embodiments of this application, see Figure 5 As shown, the shock-absorbing mechanism 5 includes a support part and a shock-absorbing part 510. The support part includes a bottom frame plate and reinforcing columns 520. The bottom frame plate is fixedly connected to the lower surface of the housing 1. Reinforcing columns 520 are respectively provided at the four corners of the bottom frame plate. Shock-absorbing parts 510 are provided between the bottom frame plates, and shock-absorbing parts 510 are provided inside each reinforcing column 520.

[0055] In some embodiments of this application, the shock-absorbing part 510 includes a connecting column 5101, a sliding plate 5102, a torsion spring 7, a sliding groove 5103, and a limiting plate 5104. The sliding groove 5103 is disposed inside the reinforcing column 520. The sliding plate 5102 is vertically slidably connected inside the sliding groove 5103. A torsion spring 7 is disposed between the lower surface of the sliding plate 5102 and the bottom wall of the sliding groove 5103. The connecting column 5101 is disposed on the upper surface of the sliding plate 5102. The upper end of the connecting column 5101 passes through the reinforcing column 520 and is fixedly connected to the lower surface of the bottom frame plate.

[0056] Understandably, the elastic buffering of the slide plate 5102 and the torsion spring 7 absorbs external impact energy through the elastic deformation of the torsion spring 7 when the slide plate 5102 slides vertically within the slide groove 5103, reducing the direct transmission of vibration to the housing 1 and ensuring the device maintains functional stability in severe vibration scenarios. The distributed support of the four corner reinforcing columns 520 evenly distributes the load on the housing 1 through the reinforcing columns 520 at the four corners of the bottom frame plate, suppressing deformation or cracking caused by local stress concentration and improving the overall structure's resistance to bending and torsion. The multi-level buffering design of the shock absorber 510 (sliding of the slide plate 5102 + spring deformation) gradually attenuates the vibration energy of different frequencies, reducing the performance degradation of precision electronic components (such as the pickup module and processor) caused by long-term vibration. The rigid fixation of the connecting column 5101 to the bottom frame plate, combined with the flexible sliding of the slide plate 5102, forms a support system that combines rigidity and flexibility, avoiding the problem of brittle fracture under impact in a single rigid structure. The coordinated limiting of the slide groove 5103 and the limiting plate 5104, through the constraint of the vertical sliding range of the slide plate 5102 within the slide groove 5103 by the limiting plate 5104, prevents elastic failure caused by excessive compression or stretching of the spring, ensuring that the damping mechanism 5 is always within the effective working range. The built-in damping of the reinforcing column 520 is integrated into the reinforcing column 520 through the damping part 510, which enhances the vibration resistance of the four corner support points without taking up additional space, and avoids tilting or displacement of the equipment due to single-point impact.

[0057] In some embodiments of this application, the pickup mechanism 6 includes a microphone 601 and a through hole 602. The outer surface of the housing 1 is provided with a through hole 602, and the microphone 601 is located inside the through hole 602.

[0058] Understandably, the directional sound wave guidance of the through-hole 602 forms a sound wave conduction channel through its opening, focusing on the direction of the target sound source (such as human voice), reducing interference from side or rear environmental noise (such as wind noise or mechanical vibration), and improving the signal-to-noise ratio of the speech signal. The near-field optimized layout of the receiver 601, embedded inside the through-hole 602, shortens the physical distance to the external sound source, reduces the attenuation of the speech signal in the air, and enhances the ability to capture low-volume or distant speech. The smooth treatment of the inner wall of the through-hole 602 reduces the reverberation effect caused by sound wave reflection and avoids speech blurring caused by echo superposition.

[0059] The voice offline transcription device for an intelligent scheduling system described in the above embodiments achieves a rigid connection between the housing 1 and external components through the cooperation of the locking groove 2 and the locking mechanism 3. This avoids displacement problems caused by vibration or external force due to traditional adsorption or clamping methods, improving the device's stability in complex environments. The adsorption mechanism 8 at the bottom of the housing 1 can adapt to different material surfaces (such as metal, glass, and plastic), providing reliable fixation in scenarios such as vehicle-mounted and industrial equipment, reducing the risk of functional interruption caused by device detachment. At the same time, the locking mechanism 3 reduces wear on the structure caused by repeated disassembly and assembly, extending its service life. The physical locking method avoids the defects of pure magnetic attraction or adhesive solutions that are prone to loosening after long-term use, improving the device's stability in continuous operation. In terms of reliability in working scenarios, the built-in layout of the pickup mechanism 6 integrates the pickup module into the housing 1. The structure of the housing 1 shields some external electromagnetic interference and reduces microphone angle shift caused by device displacement, ensuring the stability of the sound source direction and thus improving the clarity of voice signal acquisition. Furthermore, the rigid connection between the housing 1 and the locking mechanism 3 reduces mechanical noise caused by vibration. Combined with the shock absorption effect of the adsorption mechanism 8, it suppresses the interference of background noise on the voice signal in noisy environments. The direct fixing design of the voice mechanism 4 and the locking mechanism 3 avoids the problem of easy loosening or breakage of connecting cables in traditional split structures, ensuring the signal transmission stability between the voice processing module and the pickup module and reducing the probability of transcription interruption.

[0060] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
