Based on the embodiment in the utility model, all other embodiments obtained by ordinary skilled in the art without creative labor belong to the scope of the protection of the utility model.

Therefore, they cannot be understood as a limitation on the present invention.

[0024] like Figure 1 As shown, a full-range audio composite capacitor includes a housing with a capacitor core disposed therein. The capacitor core has electrodes A1 and B4, which are respectively led out of the housing. A first dielectric 2 and a second dielectric 3 are sequentially stacked on electrode A1, and a third dielectric 5 and a fourth dielectric 6 are sequentially stacked on electrode B4. Electrode A1, first dielectric 2, second dielectric 3, electrode B4, third dielectric 5, and fourth dielectric 6 form a series structure inside the housing. The housing is made of tape, plastic, or metal.

[0025] Specifically, this full-frequency audio composite capacitor realizes the effective superposition of the first and second dielectrics on electrode A and the third and fourth dielectrics on electrode B through a parallel or series structure in the shell, forming a composite capacitor core.

[0026] The material of electrode A1 and electrode B4 is metal material;

[0027] Specifically, the electrodes A1 and B4 are made of metal materials including, but not limited to, aluminum, copper, silver, or gold. The purpose of this design is to effectively suppress the temperature rise and electrochemical reaction of the capacitor during use by using different metal materials, thereby maintaining the stability of various capacitor characteristics and improving its reliability and service life.

[0028] The transmission of electric current requires a metal medium. Aluminum plating with nanometer-level thickness is commonly used on the market. Replacing the aluminum plating with 2-16 micron-thick metal foil electrodes A1 and B4 increases conductivity by 1,000 times. This higher conductivity results in faster transmission efficiency and lower capacitor losses, preserving high-frequency treble without distortion, resulting in better sound quality and closer to the original sound.

[0029] The first medium 2, the second medium 3, the third medium 5, and the fourth medium 6 are made of organic thin films. The first medium 2 and the third medium 5 are made of the same material, the second medium 3 and the fourth medium 6 are made of the same material, and the first medium 2 and the third medium 5 are made of different materials from the second medium 3 and the fourth medium 6;

[0030] Specifically, the organic film can be polypropylene film PP, polyester film PET, polyphenylene ether film PPS, polycarbonate film PC, polyphenylene naphthalene film PEN, polyvinylidene fluoride film PVDF, etc., and the first medium 2, the second medium 3, the third medium 5, and the fourth medium 6 can also be paper, and some other media can also be used as media. The two materials are separately attached to the two poles of the capacitor, and have good high-frequency characteristics and good low-frequency characteristics respectively. Now the two are combined together, that is, one pole of the capacitor is attached to the two combined materials, and the other pole is also attached to the two combined materials. The two materials are directly integrated together to complement each other in frequency, so that both high and low frequencies are taken into account. There is no need for a frequency division circuit, and full-frequency processing is directly performed, which reduces circuit complexity, improves efficiency, and saves resources.

[0031] In the second embodiment, it should also include at least (such as Figure 2 ) The first medium 2 and the second medium 3 shown are homogeneous, and the third medium 5 and the fourth medium 6 are not homogeneous.

[0032] In the third embodiment, it should also include at least (such as Figure 3 ) The first medium 2 and the second medium 3 shown in FIG. 5 are of different natures, while the third medium 5 and the fourth medium 6 are of the same nature.

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
