The existing technical solution has the following disadvantages: (1) Single fixed brain region stimulation: The structure of the equipment cannot be adjusted, the spatial position of the TMS coil is fixed relative to the user's head, and only a single preset brain region can be stimulated, so the treatment effect cannot be maximized because the equipment cannot be flexibly switched according to individual differences of users and different needs of treatment stages; (2) Serious electromagnetic interference problem: Because the structure layout is compact, the driving lines of the TMS coil and the speaker are often arranged in parallel or integrated on the same circuit board. When the TMS coil works, a strong high-frequency pulse electromagnetic field is generated instantaneously, and the electromagnetic field seriously interferes with the audio signal of the speaker through spatial radiation and line coupling, resulting in noise and distortion of the binaural beat sound stimulation, and affecting the synergistic effect of the treatment; Based on the defects of the existing solutions, a foldable multi-brain region transcranial magnetic stimulation equipment and an anti-interference method thereof are provided.

[0016] Reference Figs. 1-3 A foldable multi-brain region transcranial magnetic stimulation device, comprising an upper cover 100 and a lower cover 200, the inner surface of the upper cover 100 is attached to the user's forehead to the top occipital region, and further comprising: A folding mechanism 300 for connecting the upper cover 100 and the lower cover 200; The upper cover 100 is internally integrated with a TMS coil 1, a binaural beat speaker module 3 and an operation interface. The TMS coil 1 is fixedly installed in the central region of the inner chamber of the upper cover 100, and is used to generate a focused magnetic field penetrating the skull. The binaural beat speaker module 3 is divided into a left ear beat speaker module and a right ear beat speaker module, which are respectively symmetrically embedded and fixed on the left and right sides of the inner chamber of the upper cover 100. The binaural beat speaker module 3 is used to output acoustic stimulation of a specific frequency. The operation interface is installed on the outer surface of the upper cover 100, and contains a volume increase / decrease key 4 and a power on / mode key 5, which are convenient for user operation. The lower cover 200 internally accommodates a main control board 6 and a DC power supply port 7. The main control board 6 is fixed in the inner chamber of the lower cover 200 and is electrically connected with a TMS coil output line 8. The main control board 6 is connected with the TMS coil 1 through the TMS coil output line 8. The inner surface of the lower cover 200 is provided with a grid-shaped anti-slip structure to increase the friction with the user's head and ensure the stability of the device during the treatment process. The DC power supply port 7 adopts a hidden left and right wire outlet design and is located on the side wall of the lower cover 200. The DC power supply port 7 is used to connect an external power adapter to supply power to the main control board 6 and each module. The main control board 6 and the binaural beat speaker module 3 are electrically connected through a speaker output line 2. The folding mechanism 300 is also used to realize stepless opening and closing or specific gear opening and closing between the upper cover 100 and the lower cover 200 within the range of 0-120°. The folding mechanism 300 internally adopts a physically isolated cavity, and is arranged left and right. The speaker output line 2 preferably adopts a twisted shielded wire, which maintains the maximum physical distance with the TMS coil output line 8. The speaker output line 2 is used to clearly transmit audio signals from the main control board 6 to the binaural beat speaker module 3. The TMS coil output line 8 adopts a double-layer shielded wire, and is used to transmit high-power pulse current generated by the main control board 6 to the TMS coil 1. In the working process of the embodiment, the high-power TMS pulse current generated by the main control board 6 is transmitted through the TMS coil output line 8, and most of the strong electromagnetic field generated thereby is absorbed and reflected by the shielding layer of the TMS coil output line 8. At the same time, since the speaker output line 2 is arranged in another physically isolated cavity of the folding mechanism 300, and the speaker output line 2 also has a shielding layer, the electromagnetic interference of the former is effectively avoided. The double design of "spatial separation + independent shielding" ensures that the audio signals transmitted to the binaural beat speaker module 3 are pure and noise-free, so as to output clear and stable binaural beat sound stimulation. The spatial position of the TMS coil 1 is adjustable relative to the user's head.

[0017] The embodiment also proposes an anti-interference method of a foldable multi-brain region transcranial magnetic stimulation device, which comprises the following steps: S1: Physical space isolation: Within the folding mechanism 300 connecting the upper cover 100 and the lower cover 200, independent wiring channels are constructed for the TMS coil output line 8 and the speaker output line 2 respectively, realizing the physical space isolation of the two; S2: Independent electromagnetic shielding: The TMS coil output line 8 is applied with a first layer of electromagnetic shielding and a second layer of electromagnetic shielding, forming a double-layer shielding structure, and the speaker output line 2 is applied with at least one layer of electromagnetic shielding, and preferably adopts a twisted pair structure to suppress common-mode interference; S3: Time-sharing drive control: Program control is performed by the main control board 6, and a time-sharing drive strategy is adopted, that is, during the short moment of TMS coil 1 emitting magnetic pulse, the drive to binaural beat speaker module 3 is suspended or weakened, and during the magnetic pulse interval, the binaural beat speaker module 3 is driven with full power, which can further eliminate interference from the time domain; S4: Common ground noise discharge: The shielding layer of the main control board 6, the TMS coil output line 8 and the shielding layer of the speaker output line 2 are connected to a unified grounding point through a low-impedance path, so that the coupled common-mode noise can be effectively discharged, and the unified grounding point is preferably located on the main control board 6; The anti-interference method of the embodiment cooperates through four dimensions of space, time, shielding and grounding, and systematically solves the electromagnetic interference problem of TMS to sound stimulation.
