Description

Headphones with adjustable tone

technical field

The utility model relates to an earphone, in particular to an earphone with adjustable timbre.

Background technique

Along with the development of electronic communication technology, the application of earphone is more and more popular, and the people who use earphone can enjoy music or receive information without interfering with each other, brings many conveniences to people. Traditional earphones in the prior art are designed and debugged to produce products with certain timbre characteristics. The defect of the product is that the timbre and sense of hearing of a product are fixed. Some users are satisfied with earphones with fixed timbre and sense of hearing, while others are not. This is because each user has different requirements for the timbre of the earphones when listening to music, watching movies, or playing games. Headphone products with fixed sound characteristics cannot meet the real needs of the market. How to adjust the timbre of each earphone to meet the needs of different people, this research topic is placed in front of people. Regarding the adjustment of the timbre of the earphones, there is a way to realize it, that is, divide the audio electronic signal into many frequency bands, and adjust the strength of each frequency band separately. The disadvantage of this method is that the adjustment is inconvenient, because it is time-consuming and laborious to carefully adjust and match each frequency band separately; the second is that after the electronic EQ tuning is completed, the electrical signals of certain frequency bands are sometimes artificially amplified, and there may be distorted signals The third is the increase of the circuit, which directly leads to the increase of the product cost. People urgently hope that a kind of adjustable tone earphone with obvious tuning effect and inconspicuous increase of the cost of the product comes out.

Utility model content

The technical solution adopted by the utility model to solve the technical problem is: adjustable tone earphones, including the earphone shell, the earphone shell is composed of the shell cover and the bell mouth shell which is integrated with the shell cover, and at least one is designed on the shell cover A through hole and an adjusting device for adjusting the air flow of the through hole, the adjusting device is assembled with the shell cover.

The through holes designed on the shell cover are arranged on a straight line, or on an arc line, or in a matrix, or in a symmetrical or asymmetrical manner.

One form of regulating device for adjusting the air flow through the through hole includes a turntable, and a rotating shaft is designed at the center of the turntable, and the rotating shaft and the center hole on the shell cover are assembled together in a dynamic fit; at least one through hole is designed on the turntable , the corresponding number of through holes on the turntable and the through holes on the case cover are equal, and the arrangement is the same; a convex ring is designed on the case cover, and a ring groove is designed on the turntable. The convex ring on the case cover and the circle on the turntable The ring grooves are assembled together in a moving fit manner.

Another form of regulating device for adjusting the air flow through the through hole includes a disc and a slide plate, the disc and the shell cover are assembled together in a static fit mode, and a cavity is designed between the disc and the shell cover, and the slide plate and the shell cover The cavities are assembled together in a sliding manner, one end of the slide plate extends outside the cavity, and the other end is located in the cavity; at least one through hole is designed on the disk.

The beneficial effects of the utility model are: adopting the adjustable timbre earphone with the above structure, one or more through holes are designed on the turntable; The adjustment device in the form can adjust the ventilation volume of the through hole designed on the shell cover, so that the user can freely change the openness of the ear shell cavity, thereby having a significant impact on the timbre of the earphone, turning the earphone with a fixed timbre into a The earphones can be freely changed in timbre; the utility model has obvious tuning effect, the cost increase of the product is not obvious, does not involve the processing of electronic audio signals, does not bring additional distortion signals, and the quality of the product can be guaranteed; it can meet different According to the user's requirements, the tone of the earphone is easy to adjust and the effect is good.
