Transcranial magnetic-acoustic stimulation (TMAS) is a new non-invasive brain neuromodulation technique based on the development of traditional neuromodulation techniques. This technique applies ultrasound and magnetic field to the neural tissues together, and realizes the modulation of specific brain regions by generating induction current. With the advantages of modulation area focusing, controllable, deep stimulation depth, and non-invasiveness, it is expected to achieve clinical applications. In this paper, a magnetic-acoustic stimulation method based on pulsed magnetic field is proposed, which uses a coil to generate a pulsed magnetic field instead of a permanent magnet. This reduces the size and weight of the magnet, and is easy to operate. It is also conducive to more flexible adjustment of the value of the magnetic flux density, which increases the adjustable range of the value of the current density obtained in the target area. It helps to better achieve the effect of magnetic-acoustic stimulation as well.
