Description

[Detailed Description of the Invention] The present invention relates to an improvement in the element structure of an electrolytic capacitor.

In a conventional electrolytic capacitor, as shown in FIG. 1, a lead plate 3 is connected to two electrode foils 1 by crimping or the like, and then wound through an electrolytic paper 2 to form a capacitor element 8. do.

Next, after the capacitor element 8 was impregnated with an electrolytic solution, the lead plate 3 was connected to the external terminal 4, which had been attached in advance to the sealing plate 5 by rivets, etc. so as to be electrically conductive, and then the element fixing material 6 was injected. Insert it into the capacitor case 7 and
As shown in the figure, the opening of the capacitor case 7 was sealed by winding or the like.

When the capacitors described above are used in audio equipment, they have the disadvantage that it is difficult to obtain sound quality close to the original sound.

In other words, in recent audio technology, it is said that the sound quality changes depending on the type and structure of the many electronic components used in audio equipment, and especially for electrolytic capacitors, the sound quality varies depending on the material and structure of the parts used. It is already known from numerous documents that the sound quality is different.

For this reason, attempts have been made to create a sound quality close to the original sound by examining various parts, materials, and structures, but the only way to evaluate sound quality is to rely on the listening results of experts. Good ones are evaluated as having good sound quality.

However, changes in sound quality caused by subtle changes in materials do not necessarily lead to consensus among everyone, and repeated experiments have not been conducted to further investigate the issue.

Based on numerous previous experiments, it has been found that adding various substances to the center of an electrolytic capacitor can significantly change the sound quality.

In addition, recent audio equipment is becoming increasingly consumer-oriented, from the traditional tendency of purchasing amplifiers with good sound to the direction of selecting the sound of one's own preference.

In the sense of creating one's own sound, from the time when the audition evaluation was judged to be good based on the consensus of all the listeners,
Rather, it is moving in the direction of finding one's own sound quality even in sound quality that has been judged as negative.

As a result, electrolytic capacitors must be manufactured in many different types to suit various sound qualities, making it difficult in practice.

This proposal was devised with these points in mind.

Hereinafter, the electrolytic capacitor of the present invention will be explained with reference to embodiments shown in FIGS. 2 to 5.

First, as shown in FIGS. 2 and 3, a pair of aluminum electrode foils 1 are attached to the outer periphery of a bottomed cylindrical case 9 made of polypropylene or other chemical-resistant material, to which a lead plate 3 is connected by crimping or the like. The capacitor element 10 is formed by winding the electrolytic paper 2 in between.

Next, after impregnating the capacitor element 10 with an electrolyte,
In the bottomed cylindrical case 9 made of polypropylene or other chemical-resistant material located at the center of the winding element, there are prepared materials in which hardening resin is mixed with ground carbon powder, alumina powder, etc., metal materials such as iron materials, copper materials, etc. Insert a material 11 selected for changing the sound quality, such as a magnetic material such as a ferrite core material, into the case 9 as shown in FIG. As shown in Fig. 5, the external terminal 4 is attached to the sealing plate 5 by rivets or the like in advance.
After connecting the lead plate 3 to the capacitor, the capacitor case 7 is inserted into the capacitor case 7 injected with the element fixing material 6, and the opening of the capacitor case 7 is sealed by winding or the like, as shown in FIG. be.

The cylindrical case 9 of the above-described embodiment is connected to the condenser case 7 or the sealing plate 5 so that a selected substance 11 for changing the sound quality stored in the cylindrical case 9 can be stored from the outside of the condenser. You can also do this.

Since the electrolytic capacitor of the present invention is constructed as described above, a chemical-resistant cylindrical case 9 is provided in the center of the capacitor element 10 to house a substance 11 selected for changing the sound quality. The sound quality can be selected according to each person's preference, and it can be useful as a DIY product for audio equipment, so it has extremely great practical value.
