s34: acquiring propagation data of selected radio and radio, wherein the propagation data comprises a propagation direction, a propagation wavelength, a propagation amplitude, a propagation frequency and a propagation phase, the propagation direction is set as a reference direction, the propagation phase equipment is set as a reference phase, the propagation wavelength is set as a reference wavelength, the propagation amplitude is set as a reference amplitude, and the propagation frequency is set as a reference frequency;

s35: generating a corresponding reference matching sound wave according to the reference wavelength, the reference amplitude and the reference frequency, and performing direction propagation on the reference matching sound wave according to the reference direction and the reference phase by using a regulation and control prompting module; the regulation and control prompt module comprises a loudspeaker, and the reference matching sound waves are reverse sound waves generated by the vibration of the loudspeaker.

4. The bluetooth headset for automatically reducing noise during playing music according to claim 3, wherein the adjustment coefficient of the selected music is obtained by calculation using a formula

Wherein c1 and c2 are both expressed as preset proportionality coefficients, mu is expressed as a preset adjustment correction factor, and JYHi0 is expressed as a preset standard extrusion thickness value.
