The housing 1 is also provided with a frequency divider 3 and a moving iron unit 4 . In Fig. 2, when the user wears the earphone, the left side of the housing 1 faces the human ear canal, the right side of the housing 1 faces outward, the front side of the housing 1 faces the front of the human (such as the eyes), and the housing 1 faces the human ear canal. The rear side of the body 1 faces the rear of the person.

The frequency divider 3 is located on the right side of the moving coil unit 2 , and the moving iron unit 4 is located on the left side of the moving coil unit 2 . The housing 1 is provided with a moving coil cavity 5 for sound propagation of the moving coil unit 2 , and the moving iron unit 4 is located in the moving coil cavity 5 . The left part of the casing 1 is provided with a moving coil horn hole 6 for sound emission of the moving coil unit 2 and a moving iron sound emitting channel 7 for sound emission of the moving iron unit 4 . The input terminal of the frequency divider 3 inputs an electrical signal through a wire 8, that is, the input signal of the earphone is realized. The first output end of the frequency divider 3 is electrically connected to the moving coil unit 2, for example, it can be connected through a wire; the second output end of the frequency divider 3 is electrically connected to the moving iron unit 4, for example, it can be connected through a wire.

A sponge pad can also be set on the left side of the housing 1 to make it more comfortable to wear, but this is not necessary. If the variant according to FIG. 2 is taken into account, the size and shape of the parts depend only on the design of the earphone, and these designations are used in the description and claims only to make it easier to locate the part inside the earphone.

Of course, according to actual production, sound effects, etc., there may be one or more moving iron units 4 of the earphone, which should belong to the protection scope of the present invention.

In this embodiment, the moving coil speaker hole 6 faces to the left, the moving iron sound emitting channel 7 protrudes from the housing 1, and the moving iron sound emitting channel 7 is obliquely facing the front side, so that the sound emitting direction of the moving coil unit 2 is in line with the The sound of moving iron unit 4 emits in different directions.

This structure, improves the uniformity and therefore the quality in many cases, contributes to the fit for the user, better sound emission, etc.

The working principle of the present invention is: the frequency divider 3 provides signals for the moving coil unit 2 and the moving iron unit 4 respectively, so that the moving coil unit 2 is responsible for middle and low frequency pronunciation, and the moving iron unit 4 is responsible for high frequency pronunciation.

As shown in Figure 5, the A curve is the frequency response curve of the earphone of the present invention, and the B curve is the frequency response curve of the earplug earphone of the prior art in the figure, from left to right, the frequency 20～500 of horizontal axis is low frequency, 501 ~1.5K is the middle frequency, and after 1.5K is the high frequency. It can be seen from Figure 5 that the middle and high frequency part of the A curve is obviously higher, and the peak value of the high frequency part is also wider, while the attenuation of the B curve is relatively fast. Therefore, compared with the earplug earphones of the prior art, the earphone of the present invention has increased the thickness and analysis of the intermediate frequency, which makes people's singing more full of emotion and vitality, and has also increased the brightness analysis and extension of the high frequency, and can hear The extremely high-frequency sound makes people's sense of hearing richer, and better realizes the high-quality music effect of HIFI, that is, it can better experience the high-quality music of HIFI and bring the listener a live enjoyment.
