Description

Technical Field

[0001] The present invention relates to the technical field of music boxes, and particularly relates to a portable assembled music box. Background Art

[0002] At present, music boxes, as items with both practical value and artistic appreciation, are deeply loved by consumers. Traditional music boxes usually adopt an integrated structure, consisting of core components such as a cylinder, a comb, a spring box, etc., and a housing, and are produced in a factory through complex assembly processes. Although this structure can ensure the sound quality and stability of the music box, there are many limitations: on the one hand, the volume of the finished music box is fixed, occupying a large space during transportation, increasing the logistics cost, and the components are easily damaged during transportation due to the fragile structure; on the other hand, consumers can only buy fixed styles and cannot participate in the assembly process of the music box according to their personal preferences, lacking interactivity and personalized experience;

[0003] To solve the above problems, some music boxes have started to adopt a detachable assembly design, and users can complete the component splicing by themselves. However, the existing assembled music boxes still have obvious deficiencies. For example, their assembly methods mostly rely on connecting parts such as screws and glue. Not only is the assembly process cumbersome and time-consuming, requiring professional tools, but also screw fixation is likely to damage the surface of the parts, and glue adhesion is difficult to disassemble, which is not conducive to repeated assembly and component replacement; in addition, the assembly structure design of some music boxes is unreasonable, resulting in unstable connection of components, which is easy to loosen during use, affecting the music playback effect and service life; moreover, obvious splicing marks are visible on the appearance after most products are assembled, destroying the overall beauty and artistic value of the music box. Therefore, developing a music box with a clever structure, convenient assembly, firmness and beauty has become an urgent problem to be solved in the industry. Summary of the Invention

[0048] Working principle;

[0049] I. Working principle of the mechanical structure

[0050] 1. Power transmission of the rotating component

[0051] The rotating component takes the fixed shaft 7 as the core power source. When turning the handle at the bottom of the fixed shaft 7, the first gear 8 is driven to rotate. Since the second gear 10 and the third gear 11 at the bottom are both meshed with the first gear 8, the rotation of the first gear 8 drives the two rotating shafts 9 to rotate synchronously. Among them, the front rotating shaft 9 drives the second gear 10, and the rear rotating shaft 9 drives the two third gears 11, thereby transmitting power to the limiting component and the installation component, providing a power basis for subsequent assembly and fixing operations.

[0052] 2. Limiting component to fix the support seat 27

[0053] When the third gear 11 at the top of the rear rotating shaft 9 rotates, it drives the rack 12 meshed with both sides to move in a straight line. During the movement of the rack 12, the first clamping plates 13 at both ends and the limiting rod 14 at the bottom are driven to move. When installing the support seat 27, insert the second guiding block 26 at the bottom of the support seat 27 into the second guiding groove 3 of the base 1. At this time, rotate the fixed shaft 7, and the movement of the rack 12 causes the first clamping plate 13 to be stuck in the first clamping groove 28 inside the second guiding block 26, and at the same time, the limiting rod 14 slides into the limiting groove 6, providing double limiting fixation for the support seat 27 from the horizontal and vertical directions to ensure the stable installation of the support seat 27.

[0054] 3. Installation component to fix other parts

[0055] When the second gear 10 on the front rotating shaft 9 rotates, it drives the toothed ring seat 15 meshing with it to rotate. The toothed ring plate 16 at the bottom of the toothed ring seat 15 slides in the annular groove 5 to ensure the stability of rotation. As the toothed ring seat 15 rotates, the moving column 18 in the inner arc-shaped groove 17 of it can only move radially along the arc-shaped groove 17 due to the guiding effect of the dovetail block 20 and the dovetail groove. When other components (such as the main part of the music box) need to be installed, the first guiding block 21 at the bottom of the component is inserted into the first guiding groove 2 of the base 1, and the fixed shaft 7 is rotated to make the toothed ring seat 15 rotate. The moving column 18 drives the second clamping plate 19 to extend and snap into the second clamping groove 29 in the first guiding block 21, thereby firmly fixing the component on the base 1.

[0056] 4. Protection and storage of the telescopic component

[0057] The support block 22 slides in the first guiding groove 2 along with the first guiding block 21. After the component is installed, the telescopic frame 23 can be manually adjusted. The telescopic frame 23 can be expanded and retracted by means of pin hinge. When expanded, the protective cover 24 hinged at the top of multiple telescopic frames 23 rises, and at the same time, the annular protective plate 25 hinged outside the telescopic frame 23 also expands, protecting the internal structure of the music box; when retracted, the occupied space can be reduced, which is convenient for carrying or storage.

[0058] II. Working principle of the voice control module

[0059] 1. Audio acquisition and processing

[0060] The annular microphone array collects the user's voice commands within a range of 10 meters by virtue of the active noise reduction technology and far-field sound pickup ability. The collected audio signal is transmitted to the voice processing chip. The iFlytek offline voice recognition module integrated in the chip first recognizes and processes the local commands (such as basic control commands like play / pause, volume adjustment, etc.), and the response time is controlled within 0.3 seconds; for commands that cannot be recognized or commands that require more information support (such as song library search, personalized recommendation, etc.), the commands are uploaded to the cloud server for processing through the online AI voice engine such as Baidu DuerOS carried. Since the voice processing chip supports the recognition of mixed Chinese and English commands and dialect adaptation, it can widely meet the voice input needs of different users.

[0061] 2. Command parsing and execution

[0062] The ESP32-S3 chip on the main control module communicates with external devices (such as mobile phones, smart home systems) or cloud servers via Wi-Fi 6 or Bluetooth 5.2. After receiving the instructions parsed by the voice processing chip, the main control module processes them according to the instruction type: if the instructions are related to music playback, the main control module transmits the instructions to the audio decoding unit; if the instructions are for smart home linkage (such as controlling lights), it communicates with the corresponding devices through network protocols and executes operations.

[0063] 3. Audio Playback and Output

[0064] The audio decoding unit uses a HiFi-level CS43131 decoding chip to decode the received audio data, supporting 24bit / 192kHz high-resolution audio output. The decoded audio signal is played through a stereo speaker or output to external audio devices through external audio interfaces such as RCA and 3.5mm. At the same time, the multi-turn dialogue engine based on the NLP algorithm can understand the context meaning of user instructions and achieve natural and fluent voice interaction. For example, when the user gives an instruction like "Play a more upbeat song", the system can automatically match similar-style tracks in the music library and play them.

[0065] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
