[0003] Traditional walkie-talkies employ a distributed assembly architecture, with components such as speakers, microphones, and printed circuit board assemblies (PCBAs) installed independently inside the housing. This design necessitates the cumbersome process of locating, connecting, and securing each component individually during assembly. Furthermore, in complex operating environments, if a component malfunctions, the entire housing must be disassembled for troubleshooting. Repair operations involve the disassembly and reassembly of numerous circuits and parts, resulting in high maintenance difficulty and costs. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing a walkie-talkie, the specific solution of which is as follows:

[0005] A walkie-talkie, the walkie-talkie comprising:

[0006] The shell has an internal space for receptacle;

[0007] The inner frame is located entirely or partially within the accommodating space;

[0008] The inner frame is provided with speaker mounting positions, microphone mounting positions and printed circuit board assembly (PCBA) mounting positions. The speaker mounting positions are used to install speakers, the microphone mounting positions are used to install microphones, and the PCBA mounting positions are used to install PCBAs.

[0009] The speaker, the microphone, and the PCBA are pre-assembled in the inner frame to form an inner frame assembly. The PCBA is electrically connected to the speaker and the microphone respectively. The inner frame assembly is an independent assembly unit and is detachably connected to the housing.

[0010] In an optional embodiment, the housing includes:

[0014] In an optional embodiment, the inner frame is provided with a first connecting structure on its opposite two side edges, and the first shell and the second shell are respectively provided with a second connecting structure that matches the first connecting structure. The first connecting structure and the second connecting structure are detachably connected.

[0015] In an optional embodiment, the PCBA integrates a voice recognition unit, a transmitting unit, a receiving unit, and a signal processing unit.

[0016] The input terminal of the receiving unit is used to receive signals, the output terminal of the receiving unit is connected to the input terminal of the speech recognition unit, the output terminal of the speech recognition unit is connected to the input terminal of the signal processing unit, and the output terminal of the signal processing unit is connected to the speaker.

[0017] The microphone is connected to the input terminal of the voice recognition unit, the output terminal of the voice recognition unit is connected to the input terminal of the signal processing unit, the output terminal of the signal processing unit is connected to the input terminal of the transmitting unit, and the output terminal of the transmitting unit is used to transmit signals.

Compared to the traditional distributed assembly architecture that installs each component one by one, this application only requires a detachable connection between the inner frame assembly and the housing, reducing assembly steps and improving assembly efficiency. When a component fails, since the inner frame assembly is an independent assembly unit, it can be directly disassembled for inspection and repair without the need for extensive disassembly of the entire housing as in the traditional method. This greatly reduces the workload of disassembling and assembling circuits and parts, lowers maintenance difficulty, and saves maintenance costs and time. Attached Figure Description

[0046] Example 1

[0047] This embodiment provides a walkie-talkie, as shown in Figures 1-3 of the instruction manual. The specific solution is as follows:

[0048] A walkie-talkie, the walkie-talkie comprising:

[0049] The shell 1 has an internal accommodating space 12;

[0050] The inner frame 20 is located entirely or partially within the accommodating space 12; the inner frame 20 is provided with a speaker mounting position 21, a microphone mounting position 22 and a printed circuit board assembly (PCBA) mounting position 23, the speaker mounting position 21 is used to mount a speaker, the microphone mounting position 22 is used to mount a microphone, and the PCBA mounting position 23 is used to mount a PCBA;

[0051] The speaker, the microphone, and the PCBA are pre-assembled on the inner frame 20 to form the inner frame assembly 2; the PCBA is electrically connected to the speaker 21 and the microphone respectively; the inner frame assembly is an independent assembly unit and is detachably connected to the housing.

[0052] The housing 1 serves as the external protective frame of the walkie-talkie, and its interior forms a receiving space 12, as shown in Figure 2 of the instruction manual. This provides a stable and safe installation environment for the internal components, which can not only resist physical damage such as collisions and scratches during daily use, but also play a certain role in dustproofing and waterproofing, thus extending the service life of the walkie-talkie.

[0053] The inner frame 20 is an integrated mounting carrier for all the internal components of the walkie-talkie. The inner frame 20 takes into full account factors such as signal transmission, sound propagation and electromagnetic compatibility between various components, and sets up speaker mounting position 20, microphone mounting position 22 and PCBA mounting position 23 respectively to ensure that the components can work together without interfering with each other.

[0054] Specifically, after receiving the signal, the speaker can efficiently convert the electrical signal into clear, loud sound, providing users with a high-quality audio output experience. When the user speaks, the microphone can accurately capture the sound signal and transmit it to subsequent circuits. The PCBA (Printed Circuit Board Assembly) electrically connects the speaker and microphone, undertaking key tasks such as signal processing and control command transmission.

[0055] In the manufacturing process, the pre-assembled inner frame component 2 greatly simplifies the assembly process of the walkie-talkie, significantly improves production efficiency, and reduces labor costs. Regarding product performance, this integrated design makes the connections between components tighter and more stable, reducing signal transmission failures caused by loose wiring or poor contact, and improving the overall reliability and stability of the walkie-talkie.

[0056] In an optional embodiment, the speaker mounting position 20 employs an adjustable elastic clip structure, with the clip spacing adjustable to accommodate speakers of different sizes. The microphone mounting position 22 is configured as a slot structure with an elastic buffer layer, and retractable limiting blocks on both sides of the slot to accommodate microphones of various shapes and sizes. The PCBA mounting position 23 can adopt a standard drawer-type guide rail structure, allowing the PCBA to be easily inserted and removed along the rail; the mounting position contains multiple universal electrical connectors, enabling quick and stable electrical connections with PCBAs of different layouts and interfaces.

[0057] In an optional embodiment, the inner wall of the housing 1 is provided with an annular groove, in which a waterproof sealing ring is embedded. The edge of the inner frame assembly is provided with a sealing flange, which corresponds to the annular groove on the inner wall of the housing 1. When the inner frame assembly is installed into the housing 1, the sealing flange is embedded in the annular groove, compressing the waterproof sealing ring to achieve a good sealing effect.

[0058] In an optional embodiment, as shown in Figure 2 of the specification, the housing 1 can be a split structure, including a first housing 10 and a second housing 11, which together form the receiving space 12. This split structure design ensures protective performance while improving the ease of assembly and maintenance. Specifically, the first housing 10 can be an inverted U-shaped structure, which is fitted onto the inner frame assembly 2 from the top downwards during assembly; the second housing 11 is an upright U-shaped structure, fitted onto the inner frame assembly 2 from the bottom upwards.

[0059] The first housing 10 and the second housing 11 can be fixed together by a detachable connection (e.g., snap-fit ​​connection, threaded connection, or magnetic adsorption) to facilitate the convenient assembly and secure fixation of the inner frame assembly 2.

[0060] In an optional embodiment, a positioning groove and an elastic buckle can be provided on the edge of the first housing 10, and correspondingly, a guide boss and a limiting groove are provided on the edge of the second housing 11. During assembly, the guide boss is precisely positioned along the oblique guide angle of the positioning groove. When the two housings are fitted to the preset position, the elastic buckle is deformed by compression and then embedded into the limiting groove, forming a 360° annular fastening and locking.

[0061] Optionally, the outer surfaces of the first housing 10 and the second housing 11 may be treated with special processes, such as using a wear-resistant coating or an anti-fingerprint design, to improve the user's tactile experience and extend the durability of the device's appearance.

[0062] In an optional embodiment, the first housing 10 is detachably connected to the top of the inner frame 20, and the second housing 11 is detachably connected to the bottom of the inner frame 20. This detachable connection allows the inner frame assembly 2 to be encapsulated between the first housing 10 and the second housing 11.

[0063] As shown in Figures 1 and 4 of the specification, to ensure the stability of the inner frame assembly 2 inside the housing 1, first connecting structures 200 are respectively provided on the opposite side edges of the inner frame 20, and second connecting structures 14 corresponding to the first connecting structures 200 are respectively provided on the first housing 10 and the second housing 11. The first connecting structure 200 and the second connecting structure 14 are detachably connected. Through the detachable connection of the first connecting structure 200 and the second connecting structure 14, the inner frame 20 can be detachably connected to the first housing 10 and the second housing 11.

[0064] The first connection structure 200 is designed based on the shape, material, and stress characteristics of the inner frame 20 in the overall structure of the equipment. It can take the form of evenly distributed buckle protrusions, threaded holes, or grooved tracks with guiding functions, etc., in order to provide a stable and suitable foundation for the connection between the inner frame 20 and the housing 1.

[0065] The design of the second connecting structure 14 takes into full consideration its fit with the first connecting structure 200, connection strength, and ease of operation. For example, if the first connecting structure 200 is a snap-fit ​​protrusion, the second connecting structure 14 is designed as a corresponding elastic groove. The opening size, depth, and elastic coefficient of the groove are calculated to ensure that sufficient tightening force is provided during connection without damaging the components due to excessive compression. If the first connecting structure 200 is a threaded hole, the second connecting structure 14 is a corresponding threaded post or through hole, equipped with a suitable screw specification to achieve a reliable threaded connection.

[0066] The design of the first connecting structure 200 and the second connecting structure 14 enables the inner frame assembly 2 to be stably installed in the housing 1 without affecting its use; and enables the inner frame assembly 2 and the housing 1 to be installed quickly, improving the overall efficiency of the production line.

[0067] In order to realize the intelligence, interactivity and efficient communication of the walkie-talkie, a series of key functional units are integrated on the core control component PCBA, as shown in Figure 6 of the specification. The PCBA integrates a voice recognition unit 230, a transmitting unit 231, a receiving unit 232 and a signal processing unit 233.

[0068] The input terminal of the receiving unit 232 is used to receive signals, the output terminal of the receiving unit 232 is connected to the input terminal of the speech recognition unit 230, the output terminal of the speech recognition unit 230 is connected to the input terminal of the signal processing unit 233, and the output terminal of the signal processing unit 233 is connected to the speaker.

[0069] The microphone is connected to the input terminal of the voice recognition unit 230, the output terminal of the voice recognition unit 230 is connected to the input terminal of the signal processing unit 233, the output terminal of the signal processing unit 233 is connected to the input terminal of the transmitting unit 231, and the output terminal of the transmitting unit 231 is used to transmit signals.

[0070] As a crucial entry point for the device to interact with the outside world, the receiving unit 232 receives various external signals. These signals may originate from wireless data transmitted by other devices, sensor feedback in a specific environment, or analog / digital signals transmitted through a specific interface. Leveraging its highly sensitive receiving module and advanced signal filtering technology, the receiving unit 232 can accurately capture valid signals while effectively filtering out environmental noise interference and irrelevant signals, ensuring that the received data is accurate and clear.

[0071] Furthermore, the output of the receiving unit 232 is connected to the input of the speech recognition unit 230, forming an efficient information transmission channel. When the receiving unit 232 acquires a valid signal, it immediately converts it into a format suitable for processing by the speech recognition unit 230 and quickly transmits it to the speech recognition unit 230. The speech recognition unit 230 incorporates advanced speech recognition algorithms and a speech model library, enabling it to perform in-depth analysis of the received signal, recognize the speech signal, and accurately convert the speech content into text or corresponding command codes, providing a reliable foundation for subsequent signal processing and interactive operations.

[0072] In voice interaction scenarios, the microphone, as a key device for capturing user voice commands, is directly connected to the input terminal of the voice recognition unit 230. The microphone converts the user's voice commands into electrical signals and transmits them to the voice recognition unit 230. The voice recognition unit 230 quickly and accurately converts the user's voice commands into digital signals that the device can understand and execute.

[0073] Furthermore, the output of the voice recognition unit 230 is connected to the input of the signal processing unit 233, transmitting the recognized voice commands or related information to the signal processing unit 233. The signal processing unit 233 possesses powerful data processing and analysis capabilities. It performs multi-dimensional processing on the received signals, such as semantic analysis of voice commands to understand the user's intent; encrypting, decrypting, compressing, or decompressing the received data to ensure data security and transmission efficiency; and optimizing and adjusting the signals according to preset rules and algorithms to better meet the device's operational requirements.

[0074] In the voice interaction output stage, the output terminal of the signal processing unit 233 is connected to the speaker. After the signal processing unit 233 completes the response processing of the voice command, it transmits the generated audio signal to the speaker. Leveraging its excellent audio conversion performance, the speaker can quickly convert the electrical signal into a clear and loud sound signal for playback, promptly providing feedback to the user on the device's operation results or offering relevant information, thus achieving natural and smooth voice interaction between the device and the user.

[0075] In signal communication scenarios, the output of the signal processing unit 233 is connected to the input of the transmitting unit 231. When the device needs to send processed data or instructions to other devices or systems, the signal processing unit 233 further encapsulates and encodes the generated data before transmitting it to the transmitting unit 231. The transmitting unit 231 employs advanced radio frequency technology and a high-efficiency power amplifier circuit, enabling high-frequency modulation and power enhancement of the processed signal. This ensures that the signal can be transmitted wirelessly in a stable and reliable manner, with a long transmission distance and strong anti-interference capability, effectively guaranteeing the communication quality between the device and other devices or systems.

[0076] By highly integrating the voice recognition unit 230, transmitting unit 231, receiving unit 232, and signal processing unit 233 onto a PCBA, the number of circuit boards and space required inside the device are greatly reduced, allowing for a more compact, thinner, and easier-to-carry and install device. At the same time, this integrated design also reduces production costs, improves production efficiency, and facilitates product marketing and widespread adoption.

[0077] Meanwhile, the voice recognition unit 230, in conjunction with the microphone, signal processing unit 233, and speaker, provides users with a convenient and natural voice interaction method. Users do not need to manually operate complex buttons or interfaces; they can easily control various functions of the device simply through voice commands, greatly improving operational efficiency.

[0078] The close cooperation of the receiving unit 232, signal processing unit 233, and transmitting unit 231 forms a highly efficient and stable signal processing and communication system. The receiving unit 232 accurately receives external signals, the signal processing unit 233 performs in-depth signal processing and optimization, and the transmitting unit 231 ensures stable and reliable signal transmission. This series of processes effectively reduces errors and interference during signal transmission, improves the accuracy and stability of communication, ensures real-time and efficient communication between this device and other devices or systems, and meets the communication needs of various complex application scenarios.

[0079] As shown in Figures 1 and 3, in an optional embodiment, the walkie-talkie further includes:

[0080] The intercom button 3 is disposed on the outer surface of the housing 1, and the intercom button 3 is electrically connected to the PCBA.

[0081] Optionally, the outer surface of the housing 1 is provided with an intercom button 3. The position and layout of the intercom button 3 have been ergonomically tested to ensure that users can quickly reach it whether holding it with one hand or operating it with both hands, which greatly improves the efficiency and convenience of operation.

[0082] The intercom button 3 is electrically connected to the PCBA. When the user presses the intercom button 3, the PCBA will respond quickly and start the voice transmission function of the intercom. The user's voice signal is processed by the internal circuit and transmitted to the transmission module to achieve instant and clear voice communication.

[0083] In an optional embodiment, the walkie-talkie further includes:

[0084] Power module 4 is mounted on the inner frame 20 and is electrically connected to the PCBA;

[0085] The charging port 5 is located on the inner frame 20 and can be exposed relative to the housing 1. The charging port 5 is electrically connected to the power module 4.

[0086] Optionally, as shown in Figure 5 of the instruction manual, the walkie-talkie is equipped with a power module 4 and a charging port 5. The power module 4 is securely mounted on the inner frame 20, which provides good support and fixation for the power module 4. At the same time, its internal structure design fully considers the heat dissipation requirements of the power module 4, ensuring that the power module 4 can maintain a suitable temperature during operation and extend its service life.

[0087] Furthermore, power module 4 is electrically connected to the PCBA, providing a continuous and stable power supply to the PCBA and other functional modules through a stable power line. Power module 4 adopts high-performance battery technology and advanced power management circuitry, which can automatically adjust the output voltage and current according to the actual working status of the equipment, ensuring stable operation of the equipment under various load conditions and effectively avoiding equipment failure or performance degradation caused by power fluctuations.

[0088] The charging port 5 is also located on the inner frame 20 and is exposed relative to the housing 1. This allows users to charge the walkie-talkie without disassembling the housing 1; they can simply insert the charging cable directly into the charging port 5, making operation simple and convenient. The charging port 5 is electrically connected to the power module 4, ensuring that electrical energy can be efficiently and stably transferred to the power module 4 during charging, achieving fast charging. Simultaneously, the charging port 5 also features overcharge protection and short-circuit protection functions, effectively ensuring the safety of the charging process and preventing equipment damage or safety accidents caused by abnormal charging.

[0089] As shown in Figure 2, in an optional embodiment, the walkie-talkie further includes:

[0090] A button assembly 6 is disposed on the side of the housing 1, and the button assembly 6 is electrically connected to the PCBA.

[0091] The button assembly 6 includes volume adjustment buttons, and / or a power button, and / or a function switching button. The volume adjustment buttons allow users to flexibly adjust the volume of the walkie-talkie according to their actual needs. The power button controls the power on / off of the walkie-talkie; users can quickly turn the device on or off with a simple press, making operation simple and quick. The function switching button provides users with a variety of function options, allowing them to quickly switch between different working modes (such as walkie-talkie mode, scanning mode, etc.) to meet the needs of different scenarios.

[0092] The button assembly 6 is reasonably positioned on the side of the housing 1. Its button layout is carefully planned, with appropriate spacing and tactile differences between each button to ensure that users can easily distinguish and operate it accurately.

[0093] The button assembly 6 is electrically connected to the PCBA. Through precise circuit design and signal transmission mechanism, it ensures that every button operation can be accurately recognized by the PCBA and the corresponding function command can be executed.

[0094] The diverse button components provide users with a wealth of operating options, enabling the walkie-talkie to adapt to more complex application scenarios and meet the personalized needs of different user groups.

[0095] In an optional embodiment, the speaker mounting position 21, and / or the microphone mounting position 22, and / or the PCBA mounting position 23 are provided with protrusions, and the inner frame 20 is provided with corresponding grooves that match the protrusions, and the protrusions are engaged with the grooves.

[0096] Optionally, to improve the stability and ease of assembly of the walkie-talkie's internal structure, protrusions are provided at one or more of the speaker mounting position 21, microphone mounting position 22, and PCBA mounting position 23. The protrusions are customized according to the shape, size, and installation requirements of each component. For example, the protrusions on the speaker mounting position 21 are designed with the speaker's fixing requirements in mind, and may employ multiple small protrusions evenly arranged around the speaker's edge to ensure the speaker remains stable and evenly stressed after installation. The protrusions on the microphone mounting position 22 are designed with specific shapes at key support points based on the microphone's sensitivity and anti-interference requirements, effectively fixing the microphone and reducing the impact of external vibrations on its performance. The protrusions on the PCBA mounting position 23 are designed with a certain height and shape according to the PCBA's circuit layout and heat dissipation requirements, providing reliable support and reasonable installation space for the PCBA.

[0097] Meanwhile, the inner frame 20 is provided with corresponding grooves that match these protrusions. During assembly, simply place each component in its corresponding mounting position and press gently; the protrusions will then precisely embed into the grooves, achieving a tight connection. This ensures a stable connection between each component and the inner frame 20, preventing the components from loosening due to vibration or external force.

[0098] This stable installation structure ensures that all components of the walkie-talkie maintain optimal working condition during prolonged use. It prevents issues such as poor contact or signal interruption due to loose components, extending the walkie-talkie's lifespan, reducing maintenance costs and failure rates, and providing users with a more reliable and durable user experience.

[0099] As shown in Figure 1, in an optional embodiment, the housing 1 has a sound hole 13 for transmitting audio in the area corresponding to the microphone and / or the area corresponding to the speaker. The sound hole 13 communicates with the receiving space 12, forming a smooth acoustic channel between them, providing an unobstructed transmission path for the microphone to collect external audio signals and for the speaker to release audio.

[0100] Optionally, a sound hole 13 for transmitting audio is provided on the housing 1 in the area corresponding to the microphone and the area corresponding to the speaker 21. The sound hole 13 takes into account various factors such as the physical characteristics of audio transmission, the usage environment of the walkie-talkie, and aesthetic appearance. It may adopt a design with fine, evenly distributed circular holes, which can effectively prevent external dust, water droplets, and other impurities from entering the housing space 12, avoiding damage to the microphone and speaker 21, while ensuring smooth transmission of sound signals. Furthermore, the edges of the sound hole 13 are smoothed to avoid sharp edges reflecting or scattering the incoming sound signal, thereby reducing sound distortion and improving the clarity and accuracy of voice acquisition.

[0101] Furthermore, the sound port 13 communicates with the internal housing space 12 of the walkie-talkie. This ensures that sound can propagate efficiently and unobstructed between the housing space 12 and the external space. For example, within the housing space 12, there may be sound guiding channels or buffer chambers that cooperate with the sound port 13. These structures can guide and optimize the sound, reduce sound reflections during propagation, and further improve the quality of audio transmission.

[0102] In an optional embodiment, the outer surface of the housing 1, and / or the outer surface of the inner frame 20, and / or the outer surface of the speaker 21, and / or the outer surface of the microphone, and / or the outer surface of the PCBA, and / or all airflow contact surfaces of the sound hole portion 13 are covered with a waterproof and dustproof coating.

[0103] In complex usage scenarios (such as outdoor operations, factories, mines, and other industrial sites), the waterproof and dustproof coating enables walkie-talkies to maintain stable and reliable communication even in harsh weather conditions, meeting the needs of outdoor workers in various climatic environments. It also prevents harmful substances such as dust, oil, and chemical gases from corroding the internal components of the walkie-talkie, ensuring its stable operation over long periods in complex industrial environments, reducing equipment failure rates, improving production efficiency, extending the overall lifespan of the walkie-talkie, and saving on maintenance and replacement costs.

[0104] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
