Background

When enjoying music or learning, it is most desirable to reduce unwanted environmental noise; sometimes, when using headphones, attention is paid to the worry-saving information required by the external environment. The active noise reduction function is to generate opposite-phase sound waves equal to external noise through a noise reduction system and neutralize the noise, so that the noise reduction effect is realized. The passive noise reduction earphone mainly forms a closed space by surrounding ears, or adopts sound insulation materials such as a silica gel earplug and the like to block external noise.

The existing active noise reduction earphone is designed into an in-ear type earphone and a head-wearing type earphone, the in-ear type earphone is good in isolation of external noise, but the in-ear type earphone can bring larger air pressure to the auditory canal of a human body, has larger influence on the hearing protection of people, and the head-wearing type active noise reduction earphone is inconvenient to carry and is not suitable for going out to carry. The existing noise reduction scheme is to eliminate noise as much as possible, and does not consider that external environmental sounds need to be timely taken into consideration sometimes, and meanwhile, a longer gap exists between the ear frame and the main body of the ear hanging earphone, so that the ear frame is damaged when external acting force is applied (such as the ear frame is scraped and bumped).
