Problems solved by technology

[0003] In order to meet the requirements of listening to music or other higher voice quality, it is mainly reflected in the flatter audio frequency response curve, wider bandwidth and richer timbre for sound quality output; traditional earphones are set to high, The structure of audio in different frequency bands of medium and low frequency is generally completed by multiple moving iron units, that is, each moving iron unit corresponds to a kind of audio frequency. Such a structural design makes one earphone include multiple moving iron units. , there is a certain difficulty in its assembly; and it makes the volume of the whole earphone larger and takes up space; it leads to an increase in the final production cost; in addition, the audio adjustment range is narrow, and it is impossible to achieve a wide range of audio adjustment

Embodiment 1

[0024] Such as figure 1 As shown, an earphone includes a body 1 and an ear wire 2. One end of the ear wire 2 is connected to the body 1, and the other end is connected to an earphone plug 3. The body 1 includes a receiver 4 connected to the ear wire 2 and an earplug 5 connected to the receiver 4. ; The receiver 4 includes a shielding shell, a moving iron unit and a chip for adjusting the audio frequency of the earphone, the moving iron unit and the chip are arranged inside the shielding shell, and the chip is connected to the moving iron unit. The connection relationship between the chip and the moving iron unit is in parallel, and the chip is set with an audio module for adjusting different audio segments of the earphone.

[0025] An adjustment switch 6 is arranged on the ear wire 2, the input end of the chip is connected to the adjustment switch 6, and the output end of the chip is connected to the moving iron unit. The adjustment switch 6 includes four gears of full freque...

Embodiment 2

[0028] The rest are the same as the above-mentioned embodiment, the difference is that, as image 3 As shown, the moving iron unit includes a magnetic drive mechanism, a conductive rod 42 and a diaphragm 43 , and the magnetic drive mechanism is connected to the diaphragm 43 through the conductive rod 42 . The magnetic driving mechanism includes an armature device 411, an iron core 412, a coil 413 and a permanent magnet 414. The coil 413 and the iron core 412 are sleeved on the armature device 411, and the permanent magnets 414 are arranged on opposite sides of the inner ring of the iron core 412. And the opposite sides are consistent with the vibration direction of the armature device 411 .

[0029] Such as Figure 4 As shown, the diaphragm 43 includes a diaphragm main body 431, a connecting portion 432, a diaphragm support 433 and a film, one end of the diaphragm main body 431 is connected to the diaphragm support 433 through the connection portion 432, and the film is arran...

Abstract

The invention discloses an earphone. The earphone comprises a body and ear wires connected with the body, wherein the body comprises a receiver connected with the ear wires; the receiver comprises a shielding case, a moving-iron unit and a chip used for regulating audio of the earphone, both the moving-iron unit and the chip are arranged inside the shielding case, and the chip is connected with the moving-iron unit. By the adoption of the earphone, different audio bands are controlled through the chip, multiple moving-iron units are not needed in the earphone, the size becomes small, space is saved, and production cost and assembly difficulty are reduced. Meanwhile, the audio bands within a large range can be regulated, applicability is better, and the earphone can satisfy customers having the higher requirement for tone quality.

Description

technical field [0001] The invention relates to an earphone, in particular to an in-ear earphone. Background technique [0002] Earphones are people's portable audio. Nowadays, there are more and more requirements for earphones to be subdivided. Choosing the right earphones according to different occasions has become a symbol of trendy life. Headphones are classified according to their energy conversion methods, mainly including: moving coil method, moving iron method, electrostatic type and equimagnetic type; from the structural and functional methods, they can be divided into semi-open type and closed type; from the wearing form, the classification is: There are earplugs, ear-mounted, in-ear and head-mounted; from the number of wearers, there are single earphones and multi-person earphones; from the source of sound, they can be divided into active earphones and passive earphones; Often referred to as plug-in headphones. [0003] In order to meet the requirements of liste...
