Description

The invention relates to a silver-copper-gold alloy for an electrical, electronic and/or electrotechnical component and/or for a device for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission . The invention also relates to the use of this alloy in an electrical, electronic and/or electrotechnical component and/or device for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission, and the invention relates to a corresponding electrical, electronic and/or electrotechnical component and/or device comprising this alloy. Finally, the invention relates to an electrical, electronic and/or electrotechnical component or a corresponding component which has this alloy.

In devices for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission, for example for music reproduction, recording and/or processing, for example in loudspeakers, amplifiers, sound signal sources, microphones, pick-ups , for example guitar pick-ups, mixers and cables and/or components for these, the composition of the metals and metal alloys used in them, for example in an electrical, electronic and/or electrotechnical component, can have an influence on the timbre of the received sound and/or processed tone.

However, the metals and alloys known in the prior art are not yet optimally formed. Thus, although a warm timbre can be achieved through the use of pure copper in electrical, electronic and/or electrotechnical components in such devices, the timbre that can be achieved in this way has no transparency. Although the use of pure silver in electrical, electronic and/or electrotechnical components in devices of this type allows a timbre with a high level of transparency to be achieved, the timbre that can be achieved in this way is also cool at the same time.

However, in some areas of application, for example to achieve a certain sound impression and/or in the reproduction, recording and/or processing of sound, such as music and/or speech, it can be desirable to have a timbre with both a certain transparency and a certain To achieve heat, which is achieved by the metals and alloys known in the prior art, in particular when used in an electrical, electronic and/or electrotechnical component for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or or line, for example for music and/or voice playback, recording and/or processing, has not previously been possible to a sufficient extent.

The invention is therefore based on the object of designing and developing the alloy mentioned at the outset, the use mentioned at the outset and the component or component and/or device mentioned at the outset in such a way that the alloy when the alloy is used in an electrical, electronic and/or electrotechnical component or in a corresponding component and/or in a device for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission, in particular for music and/or speech Reproduction, recording and/or processing that allows to obtain a timbre with a certain transparency as well as with a certain warmth - and in particular also with a certain luminosity.

The object on which the invention is based is achieved by the silver-copper-gold alloy with the features of patent claim 1, the corresponding use with the features of patent claim 6 and the corresponding component or the corresponding part and/or device with the features of patent claim 9 or patent claim 12.

The silver-copper-gold alloy, based on the total weight of the alloy, includes
≥ 90.00% to ≤ 99.98% by weight silver,

In particular, the alloy can be used for an electrical, electronic and/or electrotechnical component for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or conduction, for example for music and/or voice reproduction, recording and/or processing, be designed or used, in particular the corresponding electrical, Electronic and/or electrotechnical components can be made at least partially from this alloy, in particular an electrical line, a conductor track or a connection element can be made from this alloy. In particular, the alloy is electrically conductive and can therefore itself be used or employed as an electrical component and/or in particular as part of an electronic and/or electrotechnical component or device.

Such a composition of the alloy can advantageously, especially when the alloy is used in an electrical, electronic and/or electrotechnical component for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission, for example for music and/or speech reproduction, recording and/or processing, a timbre can be achieved which is both transparent and has a certain warmth.

timbre analysis

To analyze the timbre of different metals and metal alloys, voice coils were made from the metals or metal alloys to be examined and installed one after the other in a loudspeaker. The timbres produced by the loudspeaker were then determined. Table 1: Comparative tests using a timbre analysis of a loudspeaker equipped with different voice coils made of copper, silver and alloys thereof No. Silver [wt%] Copper [wt%] Gold [wt%] timbre 1 100 warm, familiar 2 100 cool, transparent 3 99 1 less cool, transparent 4 98 2 tight, throaty 5 97 3 tight, throaty 6 98 1 1 transparent, warm, luminous

Table 1 shows that copper voice coil #1 resulted in a warm and familiar tone, while silver voice coil #2 resulted in a cool and transparent tone.

Voice coil #3, made from a silver-gold alloy of 99 wt% silver and 1 wt% gold, resulted in a transparent but less cool timbre than silver voice coil #2. The investigations of voice coil No. 4 made of a silver-gold alloy of 98% by weight silver and 2% by weight gold and voice coil No. 5 made of a silver-gold alloy of 97% by weight silver and 3 However, wt% gold showed that increasing the gold content to 2 wt% or 3 wt% resulted in a tight, throaty timbre.

Finally, Table 1 shows that voice coil No. 6, made of a silver-copper-gold alloy of 98% by weight silver, 1% by weight copper and 1% by weight gold, surprisingly produces a transparent and at the same time warm and, in particular, glowing timbre.

It follows from the above statements that different/different electrical, electronic and/or electrotechnical components and/or electrical, electronic and/or electrotechnical components can have the aforementioned silver-copper-gold alloy. Capacitors, transistors or resistors are particularly suitable here. In particular, the connection points/connecting wires of these parts and/or components can be formed from the aforementioned silver-copper-gold alloy or be or are produced from this aforementioned alloy. Particularly in the case of a capacitor, where the capacitor then has a carrier element or an insulator element, such as a plastic film or a paper film, for example, the carrier element or the insulator element is then in particular at least on one side with the aforementioned silver-copper-gold Alloy provided, in particular metallized accordingly with the aforementioned silver-copper-gold alloy. In this case, in particular, a corresponding layer of the silver-copper-gold alloy in the above-mentioned alloy composition has then been vapour-deposited onto the carrier element or onto the insulator element of the capacitor.
