Electromagnetic wave generating device Technical Field The present utility model relates to the field of electromagnetic wave application, and more particularly, to an electromagnetic wave generating device. Background Although electromagnetic waves can harm the health of human bodies, electromagnetic waves with certain frequency can promote the health of human bodies, and a plurality of special instruments which use the electromagnetic waves as a treatment method exist at present, for example, when the human bodies have scalds or joint sprains, the electromagnetic waves can be used for physical treatment through electromagnetic therapy, and the electromagnetic waves can be used for beautifying and slimming, and can be applied to electromagnetic wave physiotherapy in mattresses and pillows, and the like. However, the electromagnetic wave instrument is large and expensive, and the high use cost cannot enable the user to keep using the electromagnetic wave instrument for a long time, so that the treatment effect is weakened. Although mattresses and pillows having electromagnetic wave physiotherapy functions have been made in which electromagnetic wave generating terminals are integrated into products, electromagnetic wave generating terminals have been mainly used as electromagnetic wave generators or electromagnetic wave radiating plates in view of current products. The electromagnetic wave generator has a complex structure and usually comprises a magnet, as disclosed in publication No. CN207506856U, and is difficult to be applied to light and thin products due to the volume effect, and has high unit price, and when the electromagnetic wave generator is applied to large-area products, a plurality of electromagnetic wave generators need to be arranged, so that the price of the final product is quite high. Although the electromagnetic wave radiation plate can be applied to a relatively flat and thin product, as described in the publication No. CN204617742U, the surface of the electromagnetic wave radiation plate needs to be coated with a rare earth coating to meet the generation of electromagnetic waves, and the application of the rare earth coating also increases the cost of the product undoubtedly, so that the price of the final product is relatively expensive and difficult to popularize.
