Description

Technical Field

[0001] This application relates to the field of electrical pulse output, and in particular to a method and apparatus for electrical pulse output of ultra-long volumetric harmonic waves. Background Technology

[0002] As electrical pulse stimulation (EPS) technology is increasingly used in muscle training, physical recovery, and rehabilitation, related devices typically apply electrical pulse signals of a certain frequency and intensity to target muscle groups or neuromuscular tissues to activate muscles, assist training, or improve somatosensory feedback. In existing technologies, some devices use carrier signals combined with low-frequency rhythmic signals to form stimulation waveforms, while others combine signals of different frequencies to attempt to enhance the sense of stimulation depth and training adaptability.

[0003] However, existing technologies still have significant shortcomings in practical applications. On the one hand, current harmonic output methods are often abrupt, with waveform switching or output transitions that are not smooth enough. This can easily lead to users experiencing monotonous sensations, poor comfort, or even stinging or abrupt sensations during stimulation. On the other hand, the duration of current harmonic output is usually short, making it difficult to create a long-term, continuous stimulation process. This results in limited changes in stimulation rhythm and insufficient output stability, which in turn affects the sustained effect on the target tissue and the overall user experience. These shortcomings are particularly pronounced in application scenarios that require a balance between stimulation depth, smoothness of sensation, and output continuity.

[0004] Therefore, it is necessary to provide an electrical pulse output method for ultra-long body-shaped harmonics to solve the technical problems of the existing harmonic output method being rigid and short in duration, resulting in a monotonous user experience, poor comfort, and difficulty in forming a stable, long-term effective stimulation output. Summary of the Invention

[0005] In view of this, it is necessary to provide a method and apparatus for outputting electrical pulses of ultra-long volumetric harmonic waves to solve the above problems.

[0006] Embodiments of this application provide a method and apparatus for outputting electrical pulses of ultra-long volumetric harmonic waves, the method comprising the following steps: Receive user input for training modes or invoke preset training modes, and generate control commands; The carrier signal, ultra-low frequency signal, and low frequency fundamental signal are generated according to the control command. Frequency matching, phase calibration, and timing latching are performed on the ultra-low frequency signal and the low frequency fundamental signal to form a harmonic control signal; The carrier signal is modulated based on the harmonic control signal to form a modulated output signal; The modulated output signal is subjected to AC-DC blocking waveform filtering to form an electrical pulse of ultra-long volumetric harmonics; Output the electrical pulse of the ultra-long body shape harmonic.

[0007] In at least one embodiment of this application, the control command also generates an output intensity parameter and an output duration parameter.

[0008] In at least one embodiment of this application, the step of "performing frequency matching, phase calibration, and timing latching of the ultra-low frequency signal and the low frequency fundamental signal" specifically includes the following steps: Frequency matching is performed on the ultra-low frequency signal and the low frequency fundamental signal to establish a rhythmic correspondence between them; Phase calibration is performed on the ultra-low frequency signal and the low frequency fundamental signal after frequency matching is completed, so as to adjust the waveform position relationship between the two on the time axis. The phase-calibrated ultra-low frequency signal and the low frequency fundamental signal are time-locked to maintain a stable time correspondence between them.

[0009] In at least one embodiment of this application, the step of "modulating the carrier signal based on the harmonic control signal to form a modulated output signal" specifically includes the following steps: The harmonic control signal is converted from digital to analog to obtain an analog modulation signal; The analog modulated signal is amplified in both signal and power. The carrier signal is modulated using the amplified analog modulation signal to form a modulated output signal.

[0010] In at least one embodiment of this application, the step of "outputting the electrical pulse of the ultra-long volumetric harmonic wave" specifically includes the following steps: Read the output intensity parameter and the output duration parameter; The target output intensity is determined based on the output intensity parameter, and the target output duration is determined based on the output duration parameter. The system outputs electrical pulses of the ultra-long body wave harmonics according to the target output intensity, and stops outputting the electrical pulses of the ultra-long body wave harmonics when the current output duration reaches the target output duration.

[0011] In at least one embodiment of this application, the step of "performing AC / DC blocking waveform filtering on the modulated output signal" includes the following steps: The modulated output signal is waveform filtered by transformer coupling.

[0012] In at least one embodiment of this application, the AC-DC filtering process includes isolating the DC component in the modulated output signal and retaining the AC variation component, so that the modulated output signal after waveform filtering transitions continuously.

[0013] In at least one embodiment of this application, the lowest harmonic frequency of the electrical pulse of the formed ultra-long body-shaped wave harmonic reaches 0.033 Hz.

[0014] In at least one embodiment of this application, the single output duration of the electrical pulse of the formed ultra-long body-shaped harmonic is greater than 22s.

[0015] This application provides an electrical pulse output device for ultra-long volumetric harmonics, applicable to any method for outputting electrical pulses for ultra-long volumetric harmonics. The output device includes: The control module is used to receive user input of training modes or call preset training modes and generate control commands. The signal generation module is used to generate carrier signals, ultra-low frequency signals, and low frequency fundamental signals according to the control instructions. The harmonic coordinated control module is used to perform frequency matching, phase calibration and timing latching on the ultra-low frequency signal and the low frequency fundamental signal to form a harmonic control signal. A modulation module is used to modulate the carrier signal based on the harmonic control signal to form a modulated output signal; The waveform processing module is used to perform pass-through-intercept-direction waveform filtering on the modulated output signal to form an electrical pulse of ultra-long volumetric harmonics; The output module is used to output the electrical pulses of the ultra-long body-shaped harmonic wave.

[0016] The aforementioned method and apparatus for outputting electrical pulses of ultra-long body-shaped harmonics generate carrier signals, ultra-low frequency signals, and low-frequency fundamental signals according to control commands, moving beyond simply outputting a single electrical pulse. Secondly, by performing frequency matching, phase calibration, and timing latching on the ultra-low frequency and low-frequency fundamental signals, a stable and orderly harmonic control signal is formed, thus avoiding the problems of harsh harmonic output and monotonous rhythmic changes. Then, the carrier signal is modulated based on this harmonic control signal, resulting in a richer and more coherent stimulation rhythm in the output waveform, which is beneficial for forming long-term stimulation processes. Finally, the modulated output signal undergoes pass-through-intercept-direction waveform filtering to further improve the smoothness and stability of the output waveform, reducing abruptness and discomfort. Attached Figure Description

[0017] Figure 1 This is a flowchart illustrating an electrical pulse output method for ultra-long body-shaped harmonics according to an embodiment of this application. Detailed Implementation

[0018] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0020] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0021] according to Figure 1 This application provides a method for outputting electrical pulses for ultra-long volumetric harmonic waves, the method comprising the following steps: S10. Receive user input for training mode or call preset training mode, and generate control commands; S20. Generate a carrier signal, an ultra-low frequency signal, and a low-frequency fundamental wave signal according to the control command; S30. Perform frequency matching, phase calibration and timing latching on the ultra-low frequency signal and the low frequency fundamental signal to form a harmonic control signal; S40. Modulate the carrier signal based on the harmonic control signal to form a modulated output signal; S50. Perform AC-DC blocking waveform filtering on the modulated output signal to form an electrical pulse of ultra-long volumetric harmonics; S60, Output the electrical pulse of the ultra-long body shape harmonic.

[0022] Specifically, S10 involves receiving user input for a training mode or invoking a preset training mode and generating control commands. Users can select appropriate training modes, such as warm-up mode, continuous stimulation mode, relaxation mode, or other modes tailored to the target muscle group, through the device, host computer, mobile terminal, or preset programs. Upon receiving user input, or when a preset training mode is invoked without user input, the control system generates control commands corresponding to that mode. These control commands are not simply on / off instructions but serve as the overall control basis for the entire output process, determining the generation methods and output rhythms of subsequent signals. By generating control commands, different stimulation rhythms, durations, and somatosensory needs in different usage scenarios are uniformly constrained by the upper-level control logic, thereby generating targeted output effects for subsequent signals. Receiving or invoking modes provides clear parameter basis for subsequent signal generation, enabling customized responses to different training or rehabilitation scenarios (such as muscle activation and deep relaxation).

[0023] Further, in step S20, a carrier signal, an ultra-low frequency signal, and a low-frequency fundamental wave signal are generated according to the control command. In this application, the carrier signal can be understood as the basic carrier signal for subsequent electrical pulse output. Its main function is to be responsible for the penetration depth and energy transfer of the stimulus, providing a bottom-level output channel for subsequent harmonic control, so that the modulated rhythmic information can be stably loaded into the output link. The ultra-low frequency signal mainly provides slow rhythmic changes, used to construct rhythmic fluctuations on a long time scale, so that the final output is no longer limited to short, repetitive, and mechanical stimulation patterns. The low-frequency fundamental wave signal plays the role of the main stimulus rhythm, and its function is to form a microscopic sense of stimulus, enhance the richness of stimulus, and thus form an actual stimulus beat for the target tissue at a relatively fast rhythmic level.

[0024] By generating these three types of signals separately, each type of signal can perform its own technical function, thus laying the foundation for building richer, more coherent, and more stable output waveforms.

[0025] Furthermore, step S30 involves performing frequency matching, phase calibration, and timing latching on the ultra-low frequency signal and the low frequency fundamental signal to form a harmonic control signal. This step is one of the key aspects of this application, aiming to avoid the rhythm mismatch, waveform misalignment, and output drift problems caused by the simple mixing of different frequency signals in the prior art.

[0026] Specifically, frequency matching is performed first to establish a clear correspondence between the ultra-low frequency signal and the low-frequency fundamental signal in terms of rhythm. At this point, the ultra-low frequency signal acts as a slow rhythm modulation component, and the low-frequency fundamental signal acts as the main stimulus component. After frequency matching, the two are no longer independent and randomly superimposed, but rather have a combined relationship with a pre-defined rhythmic connection.

[0027] Next, phase calibration is performed to further adjust the waveform position relationship between the two on the time axis, so that the effective range of the low-frequency fundamental signal corresponds better to the rhythm window defined by the ultra-low frequency signal, avoiding common problems such as peak misalignment, range misalignment, or sudden output inconsistency. Timing latching is then performed to maintain the correspondence after frequency matching and phase calibration, preventing drift or offset during subsequent continuous output. By adding timing latching, rhythm and phase alignment are achieved at the initial moment, avoiding the recurrence of rhythm disorder, waveform abrupt changes, or perceptual discontinuity during prolonged continuous output.

[0028] Furthermore, in step S40, the carrier signal is modulated based on the harmonic control signal to form a modulated output signal. This harmonic control signal is then loaded onto the carrier signal, making the carrier signal the underlying carrier, and the slow rhythm changes and the main stimulus rhythm are both reflected in the output waveform. The processed, smoothed harmonic control signal is used as a modulation wave to control the amplitude, frequency, or pulse width of the high-frequency carrier signal. Because the modulation wave itself has achieved perfect frequency matching and phase alignment, the modulated output signal will also have a smooth transition in waveform changes. This ensures that the final output electrical pulse can smoothly change in stimulation intensity, rhythm, and layering with the control signal, further improving the comfort of the body.

[0029] This application employs a method of "harmonic control signal modulating carrier signal," which enables the final output waveform to maintain basic output stability while possessing richer rhythmic layers and better continuity. In other words, the carrier signal provides a stable output base, while the harmonic control signal provides orderly rhythmic changes. The two are combined through modulation rather than simple splicing, enabling the output waveform to achieve better unity in energy transfer, rhythmic organization, and somatosensory expression.

[0030] Furthermore, in step S50, the modulated output signal undergoes AC-DC blocking waveform filtering to form an electrical pulse with ultra-long volumetric harmonics. This application adds AC-DC blocking waveform filtering before output, essentially further refining the modulated output signal: on the one hand, it isolates the DC component, reducing unnecessary bias effects; on the other hand, it retains the AC variation components, ensuring that the truly effective output components related to the stimulation rhythm are preserved. Through this processing, the transition between adjacent output stages of the waveform-filtered signal becomes more continuous and natural, avoiding the abrupt sensation caused by harsh waveform switching in existing technologies.

[0031] This solution employs a "pass AC, block DC" process, using high-pass filtering or capacitive coupling to filter out DC components and low-frequency drift, retaining only pure AC signals with complete and stable waveforms. This process results in an "ultra-long body-shaped wave harmonic electrical pulse" with extremely high waveform stability and purity. It can be output stably for extended periods without changes in output characteristics or degradation of the sensory experience due to DC accumulation, thus truly achieving continuous output of the "ultra-long body-shaped wave" and solving the problem of "difficulty in forming long-duration, continuous stimulation processes" in existing technologies.

[0032] Furthermore, S60 outputs the electrical pulses of the ultra-long body-shaped harmonic waves. The target output signal, formed after ordered coordination, carrier modulation, and AC / DC waveform filtering, can be applied to the target muscle group or neuromuscular tissue of the human body through electrodes, training clothing, patches, or other electrical pulse output terminals. Because this signal has undergone rhythm adjustment, time relationship calibration, and waveform purification during its formation, it can exhibit a longer duration, smoother, more stable, and more rhythmically rich stimulation process when output, thereby creating a more continuous stimulation experience.

[0033] In summary, by generating ultra-low frequency and low frequency signals and performing rigorous frequency matching, phase calibration, and timing latching, this scheme constructs a microscopically hierarchical and macroscopically ultra-smooth composite modulation wave. Through the dual-layer modulation wave structure of "ultra-low frequency and low frequency" in conjunction with the carrier wave, independent control and coordinated output of the ultra-low frequency, low frequency, and carrier waves are achieved, greatly enhancing the sense of hierarchy of the stimulus and scene adaptability. By performing "AC blocking and DC blocking" filtering on the modulated output signal, DC components and transient interference that affect output stability are eliminated, ensuring a high degree of consistency and stability of the waveform shape of the electrical pulse during long-term output.

[0034] In one specific embodiment, the control command also generates an output intensity parameter and an output duration parameter.

[0035] In at least one embodiment of this application, the control command is used not only to control the generation and coordinated processing of carrier signal, ultra-low frequency signal and low frequency fundamental signal, but also to output intensity parameter and output duration parameter.

[0036] Specifically, after the user inputs the training mode or the system calls the preset training mode, the control module further combines the purpose of the current training mode, the stimulation requirements of the target muscle group, and the preset output rules to form a control command with output intensity parameters and output duration parameters.

[0037] The output intensity parameter characterizes the target output intensity of the electrical pulses for ultra-long body-shaped harmonics in the current training mode. Specifically, the control module can determine the target output intensity range corresponding to the user-selected warm-up mode, continuous training mode, relaxation mode, or other preset mode, and write the corresponding output intensity parameter into the control command. During actual output, the subsequent output module controls the intensity of the electrical pulses for ultra-long body-shaped harmonics based on this output intensity parameter, thereby making the output intensity of electrical pulses in different training modes differentiated and adaptable. In this way, the problems of fixed output intensity or abrupt switching in existing technologies can be avoided, making the electrical pulse stimulation more suitable for the needs of different users and different stages of use.

[0038] The output duration parameter characterizes the target output duration of the electrical pulses for ultra-long body-shaped harmonics in the current training mode. Specifically, the control module can pre-set the output duration matching the called training mode and write the corresponding output duration parameter into the control command. During subsequent output, the output module maintains the output of the ultra-long body-shaped harmonics electrical pulses according to the output duration parameter and stops outputting when the corresponding target duration is reached. This setting ensures that the electrical pulse output process is no longer arbitrarily continuous or manually interrupted, but can be stably completed according to a predetermined duration, thereby improving the controllability and consistency of the output process.

[0039] Furthermore, this application introduces output intensity parameters and output duration parameters in advance into the control command, so that the subsequent output process has the characteristics of "controllable rhythm, controllable intensity, and controllable duration", thereby further enhancing the adaptability, stability, and practicality of the electrical pulse output of ultra-long body shape harmonics.

[0040] In one specific embodiment, the step of "performing frequency matching, phase calibration, and timing latching of the ultra-low frequency signal and the low frequency fundamental signal" specifically includes the following steps: Frequency matching is performed on the ultra-low frequency signal and the low frequency fundamental signal to establish a rhythmic correspondence between them; Phase calibration is performed on the ultra-low frequency signal and the low frequency fundamental signal after frequency matching is completed, so as to adjust the waveform position relationship between the two on the time axis. The phase-calibrated ultra-low frequency signal and the low frequency fundamental signal are time-locked to maintain a stable time correspondence between them.

[0041] Specifically, frequency matching is performed on the ultra-low frequency signal and the low-frequency fundamental signal to establish a rhythmic correspondence between them. In this embodiment, the ultra-low frequency signal is mainly used to provide slow rhythmic changes, while the low-frequency fundamental signal is mainly used to form the actual stimulus beat. The role of frequency matching is to establish a rhythmic correspondence between the two based on a preset training mode or preset output rules, enabling the ultra-low frequency signal to serve as the basis for slow rhythmic modulation, while the low-frequency fundamental signal can form a specific stimulus beat based on this rhythm. Through this step, the rhythmic mismatch problem caused by the independent and arbitrary superposition of different frequency signals in the prior art can be avoided, so that the final output waveform no longer presents a scattered, repetitive, or hierarchical stimulus rhythm, but forms a composite rhythmic structure with a primary and secondary rhythmic relationship. Therefore, the role of frequency matching is to first clarify the relationship between the ultra-low frequency signal and the low-frequency fundamental signal at the rhythmic level, creating the preconditions for further fine control.

[0042] Furthermore, after frequency matching is completed, phase calibration is performed on the ultra-low frequency signal and the low frequency fundamental signal to adjust their waveform position relationship on the time axis. Phase calibration addresses the issue of "how to accurately position the correspondence on the time axis." In other words, even if the two types of signals have established a correspondence in rhythm, if their starting positions, peak and trough distribution positions, or effective interval positions on the time axis are not coordinated, it may still lead to problems such as peak misalignment, unreasonable overlap of effective intervals, or abrupt switching during the output process.

[0043] In this embodiment, the waveform positions of the ultra-low frequency signal and the low frequency fundamental signal on the time axis are further adjusted by phase calibration, so that the main stimulation interval of the low frequency fundamental signal and the slow rhythm interval corresponding to the ultra-low frequency signal form a more reasonable time coordination.

[0044] Furthermore, after phase calibration, the phase-calibrated ultra-low frequency signal and the low-frequency fundamental signal are time-locked to maintain their stable time correspondence. By adding a time-locking step, it avoids the possibility that, even if the ultra-low frequency signal and the low-frequency fundamental signal have completed frequency matching and phase calibration at the initial moment, drift, offset, or mismatch may still occur as the output time increases due to control errors, accumulated deviations, or timing changes during continuous operation.

[0045] Therefore, this embodiment uses timing latching to maintain the established rhythmic and temporal relationships, ensuring that the ultra-low frequency signal and the low-frequency fundamental signal maintain a stable corresponding state throughout the subsequent output process. This step ensures that the subsequently formed harmonic control signal is not a temporary relationship that is effective for a short time but unstable over a long period, but rather a stable control relationship that maintains order and consistency throughout a relatively long output process.

[0046] In one specific embodiment, the step of "modulating the carrier signal based on the harmonic control signal to form a modulated output signal" specifically includes the following steps: The harmonic control signal is converted from digital to analog to obtain an analog modulation signal; The analog modulated signal is amplified in both signal and power. The carrier signal is modulated using the amplified analog modulation signal to form a modulated output signal.

[0047] Specifically, the step involves performing a digital-to-analog conversion (D / A conversion) on the harmonic control signal to obtain an analog modulation signal. This step transforms the harmonic control signal, after frequency matching, phase calibration, and timing latching, from a digital control form that facilitates control and logic processing into an analog modulation signal capable of participating in the actual analog signal modulation process. Through D / A conversion, the harmonic control signal, originally biased towards the control logic layer, can be converted into an analog modulation signal that can establish a continuous modulation relationship with the carrier signal. Thus, on the one hand, the advantages of the preceding digital control in rhythm design and timing preservation are retained; on the other hand, a signal foundation compatible with the carrier signal is provided for subsequent actual modulation output.

[0048] Furthermore, after the digital-to-analog conversion is completed, the analog modulated signal is amplified and its power is increased. This step is included because although the analog modulated signal obtained after digital-to-analog conversion already has the signal form to participate in modulation, its amplitude and driving capability are usually still insufficient to directly form a stable and effective modulation effect on the carrier signal.

[0049] If further amplification is not performed at this stage, it may result in insufficient modulation depth, unclear modulation results, unclear rhythm changes after carrier carrying, or even be masked by noise, attenuation, or other signal disturbances in the subsequent output chain. Therefore, this embodiment first amplifies the analog modulation signal to improve its amplitude level and recognizability; then it performs power amplification to enhance the signal's ability to participate in subsequent modulation and drive the subsequent output chain.

[0050] This two-stage processing makes the analog modulation signal clearer not only at the signal level but also more sufficient at the drive level, thus providing a stable control foundation for subsequent carrier modulation. This application, through a chain of "digital-to-analog conversion, signal amplification, and power amplification," enables harmonic control information to be more fully and reliably reflected in the subsequent modulation output, which helps improve the stability and layering of the output waveform.

[0051] Furthermore, the step of modulating the carrier signal using the amplified analog modulation signal to form a modulated output signal is performed. This application utilizes an amplified analog modulation signal to modulate the carrier signal, enabling the carrier signal to maintain its basic carrying capacity while being governed by a harmonic control signal, exhibiting the expected slow rhythmic changes and main stimulus beat changes. The carrier signal, as the carrying entity, forms a composite output signal with hierarchical rhythmic information under the modulation of the harmonic control signal. In this way, the final modulated output signal can simultaneously possess the characteristics of stable carrying capacity, rich rhythm, and more continuous transitions, thus laying the foundation for the subsequent formation of ultra-long volumetric harmonic electrical pulses after AC / DC waveform filtering.

[0052] In one specific embodiment, the step of "outputting the electrical pulse of the ultra-long volumetric harmonic wave" specifically includes the following steps: Read the output intensity parameter and the output duration parameter; The target output intensity is determined based on the output intensity parameter, and the target output duration is determined based on the output duration parameter. The system outputs electrical pulses of the ultra-long body wave harmonics according to the target output intensity, and stops outputting the electrical pulses of the ultra-long body wave harmonics when the current output duration reaches the target output duration.

[0053] Specifically, the system pre-establishes a correspondence between training modes and output parameters. That is, when a user selects a training mode, or the system invokes a preset training mode, the control module not only determines whether to start output but also simultaneously retrieves the output intensity and duration parameters corresponding to that training mode. The output intensity parameter can correspond to a target amplitude level, target power level, or target stimulus level, while the output duration parameter corresponds to the allowed duration of this output. In this way, the output process is no longer simply a matter of starting and continuing, but rather has a clearly defined target intensity and duration before output begins.

[0054] Furthermore, after reading the output intensity parameter, the control module converts this parameter into a control quantity that the output execution unit can recognize. For example, the output intensity parameter can be converted into a target amplitude range, target amplification factor, or target drive level of the modulated output signal, so that the electrical pulses of the subsequently formed ultra-long volumetric harmonic waves are output with corresponding intensities. The purpose of this is to avoid the problem of fixed or only coarsely adjustable output intensity, so that the stimulus intensity in different training modes can more accurately match the actual needs.

[0055] Simultaneously, after reading the output duration parameter, the control module determines the target duration of this output and starts timing at the start of output. During the output process, the system continuously monitors the current output duration and compares it with the target output duration; when the current output duration has not yet reached the target output duration, it maintains the output of ultra-long volumetric harmonic electrical pulses; when the current output duration reaches the target output duration, the control module issues a stop command to terminate the current output. In this way, the output duration can have a clear boundary, avoiding the problems of arbitrary, excessively long or short output times in existing technologies.

[0056] In one specific embodiment, the step of "performing AC / DC blocking waveform filtering on the modulated output signal" includes the following steps: The modulated output signal is waveform filtered by transformer coupling.

[0057] Specifically, after the modulation output signal is formed, it first enters the transformer coupling unit located after the power amplification unit. In this embodiment, the modulation output signal sequentially undergoes D / A conversion, signal amplification, and power amplification before being input to the transformer coupling unit, and then transmitted from the transformer coupling unit to the output connection terminal.

[0058] In this process, the transformer coupling unit isolates the DC component in the modulated output signal and transmits the alternating AC component to the subsequent output stage. This ensures that the electrical pulses of the ultra-long body-shaped harmonics output laterally retain the signal components related to the rhythmic changes of the stimulus. The transformer coupling unit not only performs signal transmission between the preceding and following stages but also performs AC-pass blocking and DC-isolation processing on the modulated output signal before output, ensuring that the modulation result formed in the preceding stage enters the final output link in a form more suitable for human stimulation output.

[0059] In at least one embodiment, the transformer coupling unit may include multiple sets of transformers, each set of transformers being connected to the power amplification output terminal of the corresponding channel. A TAR01 transformer can be used as the coupling device, along with its preceding and following stages' resistor, capacitor, and inductor networks, to process and transmit the modulated output signals of each channel before outputting them to the corresponding electrical pulse output port. In this way, multiple output channels undergo relatively consistent AC-DC blocking processing before entering the training suit or electrode output terminal, thereby improving the consistency and stability of the overall output process.

[0060] By placing this processing step after power amplification and before output connection, the signal can be pre-processed before output without destroying the effective alternating current components, making the final ultra-long body-shaped harmonic electrical pulse more suitable for continuous and stable action on human target tissue.

[0061] In one specific embodiment, the AC-DC filtering process includes isolating the DC component in the modulated output signal and retaining the AC variation component, so that the modulated output signal after waveform filtering transitions continuously.

[0062] Specifically, in this embodiment, after the modulation output signal is formed, it enters a transformer coupling unit located after the power amplification stage. During its passage through this transformer coupling unit, the DC component of the modulation output signal is isolated, while the AC component corresponding to the rhythmic changes of the stimulus is retained and continues to be transmitted to the output of the subsequent stage.

[0063] Furthermore, isolating the DC component is necessary because if the modulated output signal still contains a significant DC component after its formation, it can easily lead to unnatural abrupt changes in the output waveform at stage transitions, amplitude changes, or during continuous output. This can cause users to experience abruptness, discontinuity, or discomfort when receiving stimulation. In particular, this application aims to achieve an ultra-long body-shaped harmonic electrical pulse output method, which emphasizes long duration, continuity, and smoothness of sensation. Therefore, if too much DC component is retained in the output signal, it can easily disrupt the rhythmic continuity established by the front end through frequency matching, phase calibration, timing latching, and carrier modulation. By isolating the DC component before the subsequent output stage, the final output link can focus more on retaining the AC variation components that truly participate in the expression of the stimulation rhythm, thereby improving the continuity of the overall output process.

[0064] The electrical pulses of the ultra-long volumetric harmonic waveforms in this application need to maintain dynamic output characteristics with rhythmic, hierarchical, and stimulus variations over a long time period. The alternating current (AC) variation components are the key parts characterizing these rhythmic, waveform, and stimulus variations. If these AC variation components are weakened or lost during AC-DC blocking, the harmonic control relationship formed at the front end cannot be accurately reflected in the final output, causing the output waveform to revert to a single, flat, or lacking-level waveform.

[0065] Therefore, this embodiment uses the method of "isolating DC components and retaining AC variation components" to specifically process the modulated output signal before output, so that effective rhythm information can continue to be transmitted to the output end, while components that are not conducive to smooth output are blocked in the front-end processing chain.

[0066] In one specific embodiment, the lowest harmonic frequency of the electrical pulse of the generated ultra-long body-shaped wave harmonic reaches 0.033 Hz.

[0067] Specifically, in this embodiment, the front-end control module first generates control commands based on the training mode, and accordingly generates a carrier signal, an ultra-low frequency (ULF) signal, and a low-frequency fundamental wave (LF) signal. The ULF signal serves as a slow rhythmic variation component, and the LF signal serves as the main stimulus component. These two signals are not simply superimposed; instead, they undergo frequency matching, phase calibration, and timing latching to form a harmonic control signal. This processing allows the LF signal to be controlled by the ULF rhythm over a longer timescale, thereby further elongating the final harmonic output rhythm. After the above processing, the harmonic co-regulation module can achieve a minimum harmonic frequency of 0.033Hz, while supporting longer single-output times and more diverse waveform combinations.

[0068] Furthermore, when the lowest harmonic frequency decreases to 0.033Hz, the corresponding harmonic rhythm period is significantly lengthened, allowing the same harmonic change process to unfold over a longer time scale. This facilitates the realization of slow-changing, long-duration physical output and lays the foundation for achieving richer training sensations such as warm-up, fat burning, and relaxation.

[0069] In at least one embodiment of this application, the lowest harmonic frequency of 0.033Hz is achieved as follows: The control module is preset with a complete harmonic output cycle, and this complete harmonic output cycle is set to approximately 30 seconds. An ultra-low frequency signal is generated by an ultra-low frequency signal generation module, and a low frequency fundamental wave signal is generated by a low frequency fundamental wave generation module. The harmonic coordination control module performs frequency matching, phase calibration and timing latching on the two signals, so that the low frequency fundamental wave signal is distributed within the complete harmonic output cycle according to a preset rhythm relationship. The carrier signal is modulated by the generated harmonic control signal, thereby forming a complete harmonic variation cycle that lasts for about 30 seconds at the final output.

[0070] Since a complete harmonic variation cycle is approximately 30 seconds, the corresponding lowest harmonic frequency is approximately 0.033 Hz.

[0071] It should be noted that the 0.033Hz mentioned is the final harmonic output frequency, and not the fundamental frequency directly output by the front-end ultra-low frequency signal generation module.

[0072] In one specific embodiment, the single output duration of the electrical pulse of the generated ultra-long body-shaped harmonic is greater than 22s.

[0073] Specifically, after the harmonic output begins, the output module does not quickly stop outputting within a short period of time. Instead, it maintains the continuous output of the ultra-long body-shaped harmonic electrical pulses until the preset target output duration is reached before stopping the output. In this way, the entire stimulation process is no longer manifested as a single, short-duration interval pulse, but rather as an output process with continuous rhythmic changes over a longer time range.

[0074] Furthermore, the achievement of a single output duration exceeding 22 seconds is based on the aforementioned steps of frequency matching, phase calibration, timing latching, carrier modulation, and AC / DC blocking processing. This application enables the harmonic control signal, formed after harmonic coordinated modulation, to continuously act on the carrier signal over a relatively long period of time, and to form an output waveform with continuous rhythmic changes and a smoother tactile experience through subsequent output links.

[0075] In at least one embodiment, after the system enters the output phase, the output module executes an electrical pulse output of an ultra-long volumetric harmonic based on the target output intensity and target output duration, and continuously records the current output duration during the output process. If the current output duration does not reach the target output duration, the current output is maintained. If the current output duration reaches the target output duration, and the target output duration is greater than 22 seconds, the output is stopped. In this way, the electrical pulse output process of a single ultra-long volumetric harmonic has a clear time boundary, while ensuring that this time boundary meets the requirement of being greater than 22 seconds. This ensures that the output process is long enough to reflect continuity and hierarchy, while avoiding the impact of unlimited extension of the output time on overall controllability.

[0076] In at least one embodiment of this application, in order to make the single output duration of the electrical pulse of the generated ultra-long volumetric harmonic greater than 22s, the control module presets the output duration parameter when generating the control command, and the harmonic co-regulation module performs frequency matching, phase calibration and timing latching on the ultra-low frequency signal and the low frequency fundamental signal to form a long-time harmonic control signal.

[0077] Preferably, the lowest frequency of the generated harmonics can reach 0.033Hz, which extends a complete harmonic variation cycle to approximately 30s, thus providing a rhythmic basis for a single output duration greater than 22s. Subsequently, after completing carrier modulation and AC / DC blocking processing, the output module maintains the electrical pulse output of the ultra-long volumetric harmonics according to the output duration parameters, and stops outputting when the current output duration reaches the target output duration, thereby achieving a single output duration greater than 22s.

[0078] This application provides an electrical pulse output device for ultra-long volumetric harmonics, applicable to any method for outputting electrical pulses for ultra-long volumetric harmonics. The output device includes: The control module is used to receive user input of training modes or call preset training modes and generate control commands. The signal generation module is used to generate carrier signals, ultra-low frequency signals, and low frequency fundamental signals according to the control instructions. The harmonic coordinated control module is used to perform frequency matching, phase calibration and timing latching on the ultra-low frequency signal and the low frequency fundamental signal to form a harmonic control signal. A modulation module is used to modulate the carrier signal based on the harmonic control signal to form a modulated output signal; The waveform processing module is used to perform pass-through-intercept-direction waveform filtering on the modulated output signal to form an electrical pulse of ultra-long volumetric harmonics; The output module is used to output the electrical pulses of the ultra-long body-shaped harmonic wave.

[0079] Specifically, the control module, as the upper-level control core of the entire output device, is used to determine the target type and execution rules of the current output task. In practical applications, users can input the corresponding training mode through the terminal interface, host computer, mobile application, or the device itself, such as warm-up mode, continuous stimulation mode, soothing mode, or other preset training modes. After receiving the corresponding input, or when a preset training mode is directly invoked without manual input, the control module generates control instructions adapted to that mode. These control instructions not only serve as a start-up function but can also include various control parameters related to subsequent output. The reason for setting up a control module is that without unified mode management and parameter management, although each signal module can output signals independently, these signals lack a common control basis, which can easily lead to disordered output processes and fail to meet the differentiated needs for rhythm, intensity, and duration in different scenarios. By setting up a control module, the entire output device can have mode adaptation capabilities and unified scheduling capabilities, thereby providing a clear control source for subsequent signal generation, collaborative control, and output execution.

[0080] The signal generation module is used to generate carrier signals, ultra-low frequency signals, and low-frequency fundamental signals according to the control commands. In this embodiment, the signal generation module may include multiple functional sub-units or implement multiple signal generation functions in a time-sharing manner through the same hardware platform. The carrier signal mainly serves as the basic carrier signal for subsequent output, and its role is to provide a stable carrier foundation for harmonic control information; the ultra-low frequency signal is mainly used to construct slow rhythm changes, so that the final output has rhythmic fluctuations on a long time scale; the low-frequency fundamental signal is used to form the main stimulus beat, so as to construct the actual stimulus rhythm on a shorter time scale. That is to say, these three types of signals correspond to the functional positioning of the "carrier layer", "slow rhythm layer" and "main stimulus layer", respectively. The reason for setting the generation capabilities of carrier signals, ultra-low frequency signals and low-frequency fundamental signals separately in the device, instead of having a single module directly generate the final output waveform, is that a single waveform is difficult to simultaneously take into account output stability, rhythmic change levels, and long-term output capabilities. Through the multi-signal generation method of the signal generation module, different signals can undertake different technical functions, providing a foundation for subsequent realization of richer, more coherent, and longer-term output waveforms.

[0081] The harmonic coordination control module is used to perform frequency matching, phase calibration, and timing latching on the ultra-low frequency signal and the low-frequency fundamental signal to form a harmonic control signal. This module is a crucial core component of the device, and its function is to organize the two types of rhythmic signals output by the aforementioned signal generation module from their independent states into harmonic control signals with a clear correspondence and stable time relationship. Specifically, frequency matching is used to establish the rhythmic correspondence between the ultra-low frequency signal and the low-frequency fundamental signal, allowing the ultra-low frequency signal to participate in subsequent control as a slow rhythmic modulation component, and the low-frequency fundamental signal to participate in subsequent control as the main stimulus component; phase calibration is used to further adjust the waveform position relationship between the two on the time axis to avoid peak misalignment, interval misalignment, or rhythmic abrupt changes; timing latching is used to maintain the above rhythmic and time relationships, ensuring that the two do not experience significant drift or mismatch during continuous output. The reason for setting up the harmonic coordination control module is that in existing technologies, different frequency signals are often simply superimposed or output simultaneously, lacking a fine pre-processing coordination, which easily leads to waveform hierarchy chaos, discontinuous sensation, and poor output stability. By setting up a dedicated harmonic coordination control module, the two types of rhythm signals can be organized into an orderly and sustainable control relationship at the front-end control layer, thereby providing a stable and continuous control basis for subsequent carrier modulation.

[0082] The modulation module is used to modulate the carrier signal based on the harmonic control signal to form a modulated output signal. In this embodiment, the modulation module may include structures such as a digital-to-analog converter, a signal amplification unit, and a power amplification unit, used to implement the control results formed by the aforementioned harmonic collaborative modulation module onto the actual output waveform. That is, the harmonic control signal is not directly used as the final output, but rather acts as a modulation basis on the carrier signal, so that the carrier signal, while maintaining its basic carrying capacity, reflects slow rhythm changes and main stimulus rhythm changes. The modulated output signal formed in this way, compared with the simple superposition output or switch-type loading output in the prior art, can better reflect multi-level rhythmic characteristics and maintain better output stability and continuity. The reason for setting up the modulation module is that the aforementioned harmonic control signal itself is more inclined towards control logic results. Without a dedicated modulation execution stage, it is difficult to effectively convert these control relationships into actual output waveforms; however, through the modulation module, the harmonic control results formed in the previous stage can be stably loaded onto the carrier signal, so that the final output waveform simultaneously possesses rhythmic hierarchy, continuity, and carrying stability.

[0083] The waveform processing module is used to perform AC-DC blocking waveform filtering on the modulated output signal to form an ultra-long body-shaped harmonic electrical pulse. In this embodiment, the waveform processing module is preferably located after the modulation module and before the output module to perform pre-output conditioning. Specifically, the waveform processing module can perform AC-DC blocking on the modulated output signal through transformer coupling, that is, to isolate the DC component in the modulated output signal and transmit the alternating AC component to the subsequent output terminal. By setting up a waveform processing module and implementing AC-DC blocking within it, the modulated output signal can be further purified and conditioned before entering the final output stage, so that the final ultra-long body-shaped harmonic electrical pulse is more suitable for continuous and smooth action on human target tissue.

[0084] The output module is used to output the electrical pulses of the ultra-long body-shaped harmonic waves. In this embodiment, the output module may include an output interface, a conductive connection structure, a training garment connection terminal, an electrode connection terminal, or other structures capable of outputting electrical pulse signals to the target part of the human body. The function of the output module is to transmit the ultra-long body-shaped harmonic electrical pulses, processed by the aforementioned waveform processing module, to the final user end, so that they act on the user's target muscle groups or neuromuscular tissue. Through the final output of the output module, a more continuous, natural, and layered stimulation process can be achieved, thereby improving overall physical comfort and output stability.

[0085] Therefore, this application integrates a control module, a signal generation module, a harmonic co-regulation module, a modulation module, a waveform processing module, and an output module into a complete technical system. Each component addresses different technical issues and works together to achieve the final output effect. Specifically, the control module solves the problems of mode adaptation and parameter unification; the signal generation module addresses the construction of multi-layered signal foundations; the harmonic co-regulation module addresses the relationship between rhythm and time; the modulation module addresses the conversion of control relationships into actual waveforms; the waveform processing module addresses pre-output purification and smoothness; and the output module addresses the final stimulus execution. Through this coordination, the entire output device comprehensively overcomes the problems of harsh harmonic output, short duration, monotonous sensation, and poor stability in existing technologies.

[0086] Therefore, the aforementioned method and apparatus for outputting electrical pulses of ultra-long body-shaped harmonics, by generating carrier signals, ultra-low frequency signals, and low-frequency fundamental signals according to control commands, no longer simply outputs a single electrical pulse; secondly, by performing frequency matching, phase calibration, and timing latching on the ultra-low frequency signals and low-frequency fundamental signals, the two types of rhythmic signals are first made into a stable and orderly harmonic control signal, thereby avoiding the problems of harsh harmonic output and monotonous rhythmic changes; then, the carrier signal is modulated based on the harmonic control signal, so that the output waveform has a richer and more coherent stimulation rhythm, which is conducive to forming a long-term stimulation process; finally, the modulated output signal is subjected to AC-DC blocking waveform filtering processing to further improve the smoothness and stability of the output waveform and reduce abruptness and discomfort.

[0087] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
