DETAILED DESCRIPTION
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] like Figures 1-7 As shown: A music device capable of automatically adjusting rhythm includes a tension strap 101; The tightening band 101 is equipped with a hook and loop fastener body 102, which includes a loop fastener and a hook fastener. The loop fastener is fixed to one end of the tightening band 101, and the hook fastener is fixed to the other end of the tightening band 101. The loop fastener and the hook fastener are located on opposite sides of the tightening band 101. A housing 103 is fixedly installed on one side of the tension strap 101, and an audio processing and playback module 106, a main control module 105 and a battery 107 are sequentially integrated inside the housing 103. The main control module 105 is communicatively connected to the signal acquisition module 104 to receive the basic rhythm signal input by the composer. The main control module 105 is also connected to the control button 112 to receive style instructions or scene requirement instructions input by the composer. The main control module 105 has a built-in multi-style rhythm algorithm model to generate target music rhythm instructions based on the basic rhythm signal and style instructions or scene requirement instructions, and supports dynamic optimization of rhythm speed, beat accent, and rhythm density. The audio processing and playback module 106 is communicatively connected to the main control module 105 and configured to establish an audio connection with an external smart terminal via the wireless data communication module 108 to receive the raw audio stream from the external smart terminal; the audio processing and playback module 106 adjusts the rhythm of the raw audio stream in real time according to the target music rhythm instruction; the audio processing and playback module 106 includes a Bluetooth audio receiving module for establishing a Bluetooth audio connection with a smartphone. The housing 103 is equipped with a contact mechanism 2, and the contact mechanism 2 is equipped with a signal acquisition module 104. The housing 103 is provided with a through hole adapted to the signal acquisition module 104 for capturing the composer's rhythm instruction signal. The contact mechanism 2 includes a mounting base 201 located inside the housing 103. A telescopic rod 203 is fixed between the mounting base 201 and the housing 103. A first spring 202 is sleeved on the surface of the telescopic rod 203. The two ends of the first spring 202 are fixedly connected to the mounting base 201 and the housing 103 respectively. An audio feature recognition module 109 is also installed inside the housing 103 and is connected to the main control module 105. It is used to analyze the melody direction, harmonic texture, and pitch change characteristics of the original audio stream. The housing 103 is equipped with a control button 112 for receiving style instructions or scene requirement instructions input by the composer; The earphone body 114 has two sets of earphones, which are connected to the audio processing and playback module 106 via the connecting cable 113 for playing audio materials with rhythm adjustment. The bottom of the housing 103 has a charging port 110.
[0019] A display screen 111 is also installed on the housing 103, and the display screen 111 is connected to the main control module 105; The main control module 105 is configured to simultaneously combine the composer's input instructions with the analysis results of the audio feature recognition module 109 to generate a target music rhythm instruction, thereby achieving precise matching between rhythm and core audio features.
[0020] In this implementation scheme: the music device that can automatically adjust the rhythm is used by the user to securely fix the device to the wrist or forearm using the tightening strap 101 and the Velcro body 102. The design of the Velcro's loop side and hook side being opposite to the tightening strap 101 facilitates one-handed operation and fine adjustment of tightness. After wearing, the user presses the control button 112 on the housing 103 to start the system. The main control module 105 completes a self-test, and the audio processing and playback module 106 automatically establishes an audio connection with an external smart terminal through its integrated wireless data communication module 108. The display screen 111 displays the system status, battery level, and connection information in real time. The vibration signal generated when the user rhythmically taps the surface of the housing 103 is captured by this module. When tapping, the first spring 202 of the abutment mechanism 2 undergoes elastic deformation to buffer the impact force, ensuring that the vibration signal is clear and stable and avoiding damage to internal components. The collected basic rhythm signal is converted into a digital signal in real time and sent to the main control module 105. Users input advanced semantic commands by operating the control buttons 112 on the housing 103, such as cycling through different preset music styles by short presses, or selecting a specific motion scene by rotation. These style or scene commands are encoded and sent to the main control module 105. Meanwhile, the audio processing and playback module 106 continuously receives raw audio streams from external smart terminals, while the independent audio feature recognition module 109 simultaneously performs real-time analysis on the audio stream. It extracts core features such as melody contours, harmonic textures, basic tempo, and accent positions using built-in algorithms, and generates a structured music feature report that is continuously sent to the main control module 105. The main control module 105, acting as the data processing and decision-making center, initiates the intelligent fusion processing flow after receiving the three input signals. First, it filters and extracts features from the signal acquisition module 104 to construct a user state model. Then, based on the received style or scene command, it calls the corresponding reference model from its built-in multi-style rhythm algorithm model library. This library pre-stores the mapping relationship between rhythm parameters and user state and music features under different music styles or motion scenes. Finally, through a multi-source information fusion algorithm, it comprehensively analyzes and matches the user state model, music feature report, and the called rhythm model to dynamically generate a precise "target music rhythm command." This command includes detailed parameters such as the target rhythm speed, beat accent enhancement intensity, and rhythm density adjustment parameters, aiming to make the music rhythm simultaneously adapt to the user's real-time state and audio content characteristics. Subsequently, the audio processing and playback module 106 receives this "target music rhythm command" and the original audio stream, and uses real-time digital audio processing technology to process the audio stream according to the command parameters. The processing techniques include time stretching based on phase vocoders to change tempo, transient detection and reshaping to adjust beat accents, and rhythmic remapping to adapt to rhythm density. The processed audio signal is transmitted via conductive ring 302 to connecting line 113 wound on the reel 301 of the storage locking mechanism 3. The inner and outer rotating ends of conductive ring 302 are respectively connected to connecting line 113 and the module main board to ensure circuit continuity during rotation. Finally, the signal drives the two sets of earphone bodies 114 to produce sound. Throughout the operation, users can view the Bluetooth connection status, battery level, current rhythm parameters and playback progress in real time through the display screen 111, and play, pause and fine-tune parameters through the control button 112.
[0021] Furthermore; In an optional embodiment, a storage and locking mechanism 3 for winding and preventing tangling of the connecting wire 113 is installed inside the housing 103. The storage and locking mechanism 3 includes a winding reel 301 that rotates within the housing 103 via a rotating shaft. A conductive ring 302 is installed on one side of the winding reel 301. A locking sleeve 303 is fixedly installed at the center of one side of the winding reel 301. A circular disc 304 is provided inside the locking sleeve 303. Locking pins 305 are fixedly arranged in annular intervals on the surface of the circular disc 304. One end of the locking pins 305 is designed with a truncated cone structure. A locking hole 307 adapted to the locking pins 305 is opened on one side of the locking sleeve 303. A [missing information - likely a device or mechanism] is fixedly installed on the inner side wall of the housing 103 near the locking sleeve 303. A limiting sleeve 308 has a limiting block 309 inside it for limiting and sliding. A second spring 311 is fixed between the limiting block 309 and the limiting sleeve 308. A circular hole adapted to the limiting sleeve 308 is opened on one side of the housing 103. An adjusting rod 310 is fixedly installed on the limiting block 309. One end of the adjusting rod 310 extends to the outside of the housing 103, and the other end is fixedly connected to the circular disk 304. One end of the connecting wire 113 is wound around the take-up reel 301 and connected to the inner rotating end of the conductive ring 302. The outer rotating end of the conductive ring 302 is connected to the audio processing and playback module 106 through a wire. A counterweight ball 306 is fixedly installed on the outer surface of the locking sleeve 303.
[0022] In this embodiment: When the user needs to wear the headphones, first press the adjusting rod 310 on one side of the housing 103. The adjusting rod 310 drives the circular disc 304, which is fixedly connected to it, to move closer to the locking sleeve 303. The locking pin 305 on the surface of the circular disc 304 moves accordingly and separates from the locking hole 307 on the locking sleeve 303, releasing the locking state between the locking sleeve 303 and the winding reel 301. At this time, the user can pull the connecting cable 113. The winding reel 301 rotates under the pulling force, releasing the connecting cable 113 until the headphone body 114 is pulled to a suitable wearing length. After releasing the adjusting rod 310, the second spring 311 in the limiting sleeve 308 restores its elastic deformation, pushing the limiting block 309 to reset, thereby driving the circular disc 304 and the locking pin 305 to reset. The locking pin 305 re-inserts into the locking hole 307, relocking the locking sleeve 303 and the winding reel 301, preventing the connecting cable 113 from extending or retracting arbitrarily. The counterweight ball 306 fixed to the outer surface of the locking sleeve 303 ensures that the locking sleeve 303 remains stable due to gravity during the rotation of the winding reel 301, ensuring that the locking hole 307 and the locking pin 305 can be precisely aligned, thus improving the reliability of the locking operation. Subsequently, the user wears both sets of earphone bodies 114 on their ears to receive the audio processed by the audio processing and playback module 106.
[0023] Furthermore; In an optional embodiment, the earphone body 114 is provided with a latching mechanism 4. The latching mechanism 4 includes a rectangular groove opened on the side of the two sets of earphone bodies 114 that are far apart from each other, and a rectangular plate 401 is slidably limited in the rectangular groove. A third spring 402 arranged symmetrically is fixed between the rectangular plate 401 and the earphone body 114. A latching groove 403 is opened on the side of the two sets of earphone bodies 114 that are close to each other, and a latching opening 404 is opened on the top of the housing 103.
[0024] In this embodiment: After use, press the adjustment lever 310 again to release the lock of the take-up reel 301. Under the action of the elastic restoring force of the take-up reel 301 itself or the built-in restoring mechanism, the connecting wire 113 is automatically wound onto the take-up reel 301, preventing the connecting wire 113 from getting tangled. After storage, release the adjustment lever 310 to lock it. At the same time, the earphone body 114 can be fixed by the snap-fit mechanism 4: bring the two sets of earphone bodies 114 close to each other, so that the rectangular plate 401 slides in the rectangular groove and presses against each other, and the third spring 402 is compressed; insert the earphone body 114 after it is pressed against the snap-fit slot 404 on the top of the housing 103, and after releasing the earphone body 114, the third spring 402 rebounds, driving the two sets of earphone bodies 114 away from each other, so that the snap-fit slot 403 is locked at both ends of the snap-fit slot 404, realizing the limiting snap-fit locking of the earphone body 114, preventing the earphone from shaking or falling off at will, and improving the overall neatness of the device storage. This solution directly captures the composer's tapping motions as rhythmic instructions through the signal acquisition module 104, eliminating the need for professional arrangement skills. Composers can input their creative intentions anytime, anywhere through simple tapping. Combined with the real-time calculation of the main control module 105 and the dynamic adjustment of the audio processing module, it achieves the instant conversion of inspiration and rhythm, completely solving the problem of delayed inspiration expression in traditional composition and making the creative process smoother and more efficient. The dual-input dimension ensures rhythm adaptability, receives dynamic instructions from the composer in real time, and accurately responds to changes in creative intent. The audio feature recognition module 109 deeply analyzes the core features of the original audio, such as melody and harmony. The main control module 105 combines the two types of information to generate the target rhythm, so that the rhythm not only matches the composer's needs, but also highly matches the emotional tone and musical structure of the audio itself, avoiding the problem of rhythm rigidity and greatly improving the artistic expression and harmony of the musical work. The device features a lightweight design with a strap 101 and Velcro strap 102, allowing it to be securely fastened to the wrist, arm, or other parts of the body without hindering the composer's movement. The combination of the signal acquisition module 104 and the contact mechanism 2 ensures accurate capture of rhythmic commands even during movement, while the buffer structure prevents signal deviation caused by device shaking. It is perfectly suited for outdoor and mobile creative scenarios, freeing composers from spatial limitations. The storage and locking mechanism 3 achieves orderly winding of the connecting cable 113 through the winding reel 301. With the locking function of components such as the locking sleeve 303 and locking pin 305, the length of the connecting cable 113 can be quickly adjusted and fixed, effectively preventing tangling. The snap-fit mechanism 4 realizes convenient locking when the headphones are not in use, preventing the headphones from shaking randomly, improving the overall integrity and ease of use of the device, and solving the problem of inconvenience in the use of audio transmission components in the prior art.
