In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0020] Example like Figure 1-2 As shown, this embodiment provides a triple stimulation ear therapy device, including a main unit 1; an ear therapy terminal 2 connected to the main unit 1; pulse signals from the left ear therapy terminal connected to the main unit 1 are connected to a first electrode 3, pulse signals from the left ear therapy terminal connected to a second electrode 4, pulse signals from the right ear therapy terminal connected to a first electrode 5, pulse signals from the right ear therapy terminal connected to a second electrode 6, a shielded ground wire connected to an electrode 7, audio signals from the left ear therapy terminal connected to a first electrode 8, audio signals from the left ear therapy terminal connected to a second electrode 9, audio signals from the right ear therapy terminal connected to a first electrode 10, and audio signals from the right ear therapy terminal connected to a second electrode 11. First pulse output electrode 12; Second pulse output electrode 13; Ear acupoint electrode 14; Audio signal transducer 15; The device includes an elastic connecting bridge 16 and an elastic neck-hanging U-shaped rod 17. The elastic neck-hanging U-shaped rod 17 is connected to the audio signal transducer 15 via the elastic connecting bridge 16. The first pulse output electrode 12, the second pulse output electrode 13, and the auricular acupuncture point 14 are disposed on the ear assembly connected to the audio signal transducer 15. The ear assembly is connected via lines to the left ear therapy terminal pulse signal input first electrode 3, the left ear therapy terminal pulse signal input second electrode 4, the right ear therapy terminal pulse signal input first electrode 5, the right ear therapy terminal pulse signal input second electrode 6, the left ear therapy terminal audio signal input first electrode 8, the left ear therapy terminal audio signal input second electrode 9, the right ear therapy terminal audio signal input first electrode 10, and the right ear therapy terminal audio signal input second electrode 11 on the host.

[0021] The first pulse output electrode 12 and the second pulse output electrode 13 are arranged adjacent to each other on the ear assembly, and the acupuncture point 14 is located beside or below the first pulse output electrode 12 and the second pulse output electrode 13.

[0022] The host 1 and the ear therapy terminal 2 are connected by a multi-core cable. The multi-core cable includes wires that correspond to the following terminals: left ear therapy terminal pulse signal input first electrode 3, left ear therapy terminal pulse signal input second electrode 4, right ear therapy terminal pulse signal input first electrode 5, right ear therapy terminal pulse signal input second electrode 6, shielded ground wire input electrode 7, left ear therapy terminal audio signal input first electrode 8, left ear therapy terminal audio signal input second electrode 9, right ear therapy terminal audio signal input first electrode 10, and right ear therapy terminal audio signal input second electrode 11.

[0023] The audio signal transducer 15 is used to convert audio electrical signals into vibration signals and transmit them to the ear.

[0024] The elastic connecting bridge 16 is an elastic component that can undergo elastic deformation with the wearing action.

[0025] The elastic neck-hanging U-shaped rod 17 is made of a flexible and resilient material to adapt to the neck shape of different wearers.

[0026] The host 1 sets the envelope frequency of the electrical stimulation pulse, the difference frequency of the audio signal scale, and the difference frequency of the auricular acupoint tapping. All three fall within the δ, θ, α, or β brainwave frequency bands and are at the same or similar frequencies to form a triple stimulation resonance.

[0027] The host provides at least three pulse polarity modes: positive pulse, negative pulse, and alternating positive and negative pulse, and provides thirteen envelope frequency selection levels of 1-3 Hz, 4-11 Hz, and 12-13 Hz for each polarity mode, corresponding to δ, θ, α, and β brain waves respectively.

[0028] The host 1 has a built-in music library. The adjacent pitch difference frequencies of its music segments are classified and marked as δ, θ, α or β categories. The host 1 automatically selects a music category that matches the current electrical stimulation envelope frequency for output, so as to achieve electrical stimulation-brainwave music synchronization.

[0029] The host 1 supports unilateral or bilateral working modes and can independently turn off electrical stimulation or audio output to meet the needs of pure stimulation, pure sound therapy or unilateral treatment.

[0030] This embodiment also provides a treatment method for simultaneously applying triple stimulation to the ear using the aforementioned triple stimulation ear therapy device, including the following steps: a) Wear the left and right ear therapy terminals on the user's ears respectively, so that the inner auricular electrode and the outer auricular electrode clamp the auricular vagus nerve distribution area, and the ear acupoint protrusions abut against the depression acupoints below the ear root. b) The main unit outputs simultaneously via a pluggable composite connector: The electrical stimulation pulse signal has its envelope frequency set in any brainwave frequency band of 1-3 Hz, 4-11 Hz or 12-13 Hz; the audio signal has adjacent pitch difference frequencies of musical segments that are pre-classified and belong to the same δ, θ, α or β category as the envelope frequency. c) The audio transducer converts the audio signal into mechanical vibration, which is transmitted through the skull and generates synchronous vibration on the ear acupoint, so that the ear acupoint performs synchronous mechanical tapping on the acupoint at the root of the ear and the infrared diode emits infrared light pulses at the same frequency. d) Formed simultaneously on one or both ears: The triple stimulation of vagus nerve electrical stimulation, brain wave audio resonance, and acupoint tapping-infrared light, with the frequencies of the three stimulations being the same or similar to each other, continuously acts on the ear area to achieve synergistic regulation of the autonomic nervous system, emotions, and meridians.

[0031] Stimulation methods like Figures 3 to 6 As shown, 1. Electrical stimulation: Pulsed current is applied to the vagus nerve area (A, B, C) of the auricle via inner and outer electrodes.

[0032] 2. Audio stimulation: The vibration of the oscillator travels through the skull → cochlea → central nervous system, and the difference frequency of the music is in the same frequency band as the pulse envelope.

[0033] 3. Acupoint tapping - infrared light: The vibrator vibrates → the Bian electrode mechanically taps point D; at the same time, the infrared diode emits light pulses at the same frequency as the audio, realizing the dual external treatment of "force-light".

[0034] Synchronous resonance mechanism (core) Electrical envelope frequency = music difference frequency dominance value ≈ Bian pole tapping difference frequency, the three frequencies are consistent or close to each other, forming phase synergy, maximizing nerve-meridian-brain wave coupling.

[0035] Usage Mode Bilateral or unilateral options available; Electrical stimulation / audio / triple independently switchable; The LCD displays parameters in real time, and it supports USB charging.

[0036] Compared with the prior art, the beneficial effects of the present invention are: The triple stimulation expands the treatment dimension from "point" to "surface + depth", significantly improving clinical effectiveness and comfort.

[0037] The frequency resonance enhances the synchronous regulation of the vagus nerve, brain waves, and meridians, thus shortening the treatment course.

[0038] Ear acupuncture incorporates the theory of "original points on the head" from natural medicine, expanding its indications.

[0039] Composite plug + shielded twisted pair, high signal isolation, and tangle-free wearing.

[0040] Unilateral working mode saves energy and is suitable for unilateral diseases or daily health care.

[0041] USB charging and large-screen interaction eliminate the need for frequent battery changes and the inconvenience of small-screen operation.

[0042] Example 1 Bilateral triple stimulation The user wears the left and right ear therapy terminals → the neck-hanging U-shaped rod automatically clamps them; The host selects the "Anxiety-Relaxation" prescription: pulse envelope 9 Hz (α), music difference frequency α set; After activation, electrical stimulation, audio, tapping, and infrared output are simultaneously provided for 30 minutes. The music stops automatically when finished, and the user can remove the device. Clinical trials (n=60) showed a 42% increase in the number of people with a ≥50% decrease in HAMA scores.

[0043] Example 2 Unilateral pure sound therapy With electrical stimulation off, only the right ear's audio oscillator is active, and the difference frequency is selected as delta wave (2 Hz). It is used for midday naps, and wearing it for 15 minutes can significantly prolong the deep sleep period.

[0044] Example 3 Pure stimulation without music, with audio turned off, selected 1-3 Hz delta envelope, bilateral electrical stimulation for 20 minutes, used to help sleep at night, resulted in an average decrease of 3.7 points in PSQI score.

[0045] Triple Stimulation Synchronous Resonance Algorithm (1) Frequency-matched electrical stimulation envelope frequency Fe is selected by the user / prescription (1-3Hz, 4-11Hz, 12-13Hz, three levels in total, 13 levels); (2) After the above envelope frequency is selected, the subset of brainwave music library classified according to music difference frequency will be automatically matched for the user to select. (3) The striking difference frequency F is calculated by subtracting the frequency values ​​of each adjacent note name in the musical melody and taking the absolute value: Fi = | Front frequency Fi - Back frequency Fi + 1 | Hz If more than 60% of a track's Fi frequencies fall within the α range, then the track is classified as α brainwave music, and so on. The higher the percentage, the more pronounced the brainwave category classification. The host music library uses this formula to guide track selection; specific brainwave music can only be selected within a specific frequency range to find suitable tracks. Composers can also create specific brainwave music tracks using this formula.

[0046] (4) Brainwave classification of a piece of music (which can be named Lu's criterion): When (|Fi-Fi+1|∈1-3Hz) ≥60%, brainwave music is classified as delta. When (|Fi-Fi+1|∈4-7Hz)≥60%, brainwave music is classified as θ; When (|Fi-Fi+1|∈7-11Hz)≥60%, brainwave music is classified as α; When (|Fi-Fi+1|∈12-13Hz)≥60%, brainwave music is classified as β; (3) Infrared emitting tube (a) The ear acupuncture point has two built-in infrared emitting diodes (integrated in one light cap), both with a wavelength of 940nm. Alternatively, one wavelength can be infrared 940nm and the other near-infrared 640nm. (b) The two diodes reuse the audio drive signal of the audio oscillator by full-wave rectification and current-limiting resistor.

[0047] (c) The power of the infrared emitting tube is less than 100mW, and its main function is to inject light wave stimulation information into the meridians through acupoints. Some studies suggest that the liquid crystal molecular state in the meridians is a high-speed information channel for infrared and near-infrared light.
