Detailed ways

Further details will be given below in conjunction with the preferred embodiments shown in the accompanying drawings.

As shown in Figures 1 and 2, the first embodiment of the headphone of the present invention includes a casing 1, a steel bar 2, a protective sheet 3, a lower head clip cover 4, a head clip upper cover 5, a bracket 6, and a backing plate 7 , speaker 8, circuit board 9, support plate 10, transparent plate 11, ear shell 12, line cover 13, wire 14, audio controller 15, audio plug 16, USB plug 17 and ear cover 18.

Wherein, tube 1, steel bar 2, protective sheet 3, head clip lower cover 4 and head clip upper cover 5 constitute the head-mounted structure of the earphone, pad 7 and ear shell 12 constitute the shell of the earphone, speaker 8, circuit board 9 , the support plate 10 and the transparent plate 11 are located in the inner cavity of the housing, the ear shell 12 has a central opening, and the transparent plate 11 is arranged at the central opening. The transparent plate is provided with at least one buckle bent to one side, and the support plate is provided with slots for matching with these buckles, the support plate has a hole in the center, and the printed circuit board is fixed on the support plate and the transparent plate 11 are not on the same side, and the LED is located within the boundary of the opening in the center of the support plate. The speaker is located between the printed circuit board and the backing plate, and the backing plate has mesh openings to allow the sound to pass through effectively. The earmuffs 18 wrap the shell of the earphone. In fact, the transparent plate 11 plays the role of light penetration here, so it can also be replaced by a non-transparent material with appropriate light-transmitting openings on it.

The USB plug 17 is used as a power plug, and can obtain power from an external USB host device to provide energy for the circuit in the earphone.

The sound source signal sends the audio signal to the speaker 8 through the audio plug 16, the connecting wire and the audio controller 15, and the signal is also sent to the circuit board 9 at the same time. The circuit on the circuit board drives the LED to produce light source changes according to the frequency and current of the sound source. That is to say, the intensity and color of the LED light can be changed by changing the volume arbitrarily.

Since the above-mentioned circuit belongs to the existing mature technology, it will not be repeated here.

It can be seen that in this structure, the light-emitting circuit inside the earphone can control the LED to emit light, and provide a light-transmitting window to emit light, so as to provide a decorative function for the earphone.

As shown in Figures 3 and 4, the second embodiment of the headphone of the present invention includes a casing 1, a steel bar 2, a protective sheet 3, a lower head clip cover 4, a head clip upper cover 5, a bracket 6, and a backing plate 7 , Speaker 8, decoration 19, support plate 10, transparent plate 11, ear shell 12, line cover 13, wire 14, audio controller 15, audio plug 16 and ear cover 18. Compared with the first embodiment, the decorative board 19 is added, while the circuit board 9 and the USB plug 17 are omitted. With this structure, the decorative object 19 is arranged between the transparent plate 11 and the support plate 10. The decorative object 19 can be: a printed product, by printing technology, the exquisite patterns of landscape painting, calligraphy art, folk art, etc. are printed on the colored paper ; Paper-cut works, making exquisite patterns through folk paper-cutting art; photographic works, making exquisite patterns through photography; calligraphy works; embroidery works; knitted products; paintings. Obviously, if the decoration 19 is paper or fabric or a flat plate, it can be pasted on the transparent board 11 on the front side or pasted on the support board 10 on the back side, and the content on it can be displayed through the transparent board 11 . The transparent plate 11 can be made of organic glass, PC (polycarbonate), crystal, silicate glass, SAN (styrene-acrylonitrile) and other transparent materials.

It can be seen that, compared with the structure of Embodiment 1, the realization of the decorative function of Embodiment 2 depends on the pattern and color of the decoration 19 itself, without the need for earphones to provide light sources, and without the need for circuit board 9 and USB plug 17.

As shown in Figures 1 and 5, the third embodiment of the headphone of the present utility model includes a casing 1, a steel bar 2, a protective sheet 3, a lower head clip cover 4, a head clip upper cover 5, a bracket 6, and a backing plate 7 , speaker 8, circuit board 9, support plate 10, transparent plate 11, ear shell 12, line cover 13, wire 14, audio controller 15, audio plug 16, USB plug 17, earmuff 18 and decoration 19.

It can be seen that Embodiment 3 is actually a combination of Embodiment 1 and Embodiment 2. It is conceivable that decoration 19 can also be an active electronic display screen, such as a liquid crystal screen, which can provide rich and colorful video content. Then, in addition to the function of decoration, the earphones can allow both bystanders and users to obtain the necessary spiritual/visual enjoyment. In this way, the decoration and background light source can be provided by LED lighting, and the visual enjoyment can also be provided by the pattern and color of the decorative object 19 itself.

The best embodiment described above is intended to specifically illustrate the ideas of the present utility model, including: 1. Set a light-transmitting window on the ear shell; 2. Use an external power plug to obtain circuit work energy; Decorations are set behind the light window. The implementation of the utility model is not limited to the methods disclosed in the above-mentioned preferred embodiments. Any specific headphones obtained through simple deduction and replacement based on the above-mentioned design idea belong to the implementation of the utility model.
