Description

[0001] The invention initially relates to the use of a silver-copper-gold alloy according to claim 1. Furthermore, the invention relates to an electrical, electronic and / or electrotechnical component for sound reproduction and / or recording and / or for sound signal processing, output, reception and / or transmission, comprising the aforementioned silver-copper-gold alloy according to claim 6.

[0002] In devices for sound reproduction and / or recording and / or for sound signal processing, output, reception and / or conduction, for example for music reproduction, recording and / or processing, for example in loudspeakers, amplifiers, sound signal sources, microphones, pickups, for example guitar pickups, mixing consoles and cables and / or components therefor, the composition of metals and metal alloys used therein, for example in an electrical, electronic and / or electrotechnical component, can have an influence on the timbre of the sound output, received and / or processed via it.

[0003] DE 10 2009 013 983 A1 concerns a transformer for low-frequency signals.

[0004] DE 696 29 613 T2 discloses an electrically conductive multilayer film or a transparent electrode substrate and a liquid crystal display device, wherein a silver-copper-gold alloy is used.

[0005] For example, JP 2002 140 929 A describes components for use in liquid crystal displays, using certain silver-copper-gold alloys to achieve high weather resistance with low resistance. This applies to films and membranes.

[0006] JP 2002 141 242 A also discloses electrical components that are coated with a silver-copper-gold alloy to achieve weather resistance.

[0007] Finally, DE 600 22 951 T2 discloses alloys for electronic components, in particular in connection with liquid crystal display panels for the realisation of specific resistances.

[0008] However, the metals and alloys known in the prior art are not yet optimally formed. For example, the use of pure copper in electrical, electronic, and / or electrotechnical components in such devices can achieve a warm timbre, but the resulting timbre lacks transparency. The use of pure silver in electrical, electronic, and / or electrotechnical components in such devices can achieve a timbre with high transparency, but the resulting timbre is also cool.

[0009] 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 may be desirable to achieve a timbre with both a certain transparency and a certain warmth, which has not been possible to a sufficient extent to date using 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 conduction, for example for music and / or speech reproduction, recording and / or processing.

[0010] The invention is therefore based on the object of designing and developing the use of the alloy or the component mentioned at the outset in such a way that the alloy, when 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, enables the achievement of a timbre with both a certain transparency and a certain warmth - and in particular also with a certain luminosity.

[0011] The problem underlying the invention is solved for use with the features of patent claim 1 and for the corresponding component with the features of patent claim 6.

[0012] The silver-copper-gold alloy consists of, based on the total weight of the alloy, ≥ 97.50 wt% to ≤ 98.50 wt% silver, ≥ 0.75 wt% to ≤ 1.25 wt% copper and ≥ 0.75 wt% to ≤ 1.25 wt% gold.

[0013] The alloy can be designed or 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 transmission, for example for music and / or speech reproduction, recording, and / or processing. The corresponding electrical, electronic, and / or electrotechnical component is at least partially made of this alloy, in particular a connection element is made of this alloy. The alloy is electrically conductive and can therefore itself be used or employed as an electrical component and / or as a component of an electronic and / or electrotechnical component or device.

[0014] Such an alloy composition can advantageously achieve a timbre that is both transparent and possesses a certain warmth 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 transmission, for example for music and / or speech reproduction, recording, and / or processing. Furthermore, the timbre of an alloy with such a composition can advantageously also possess luminosity.

[0015] In the sense of the invention, the term "consist" in connection with the alloy composition can be understood in particular to mean that the alloy, in addition to the specified elements, may also contain traces of other elements in amounts customary for impurities in alloys, for example in the mass-related ppm range, for example of < 0.0050 wt.%, for example of < 0.0040 wt.%, for example of < 0.0030 wt.%, in particular in each case per other element.

[0016] For example, the alloy may comprise, based on the total weight of the alloy, ≥ 97.50 wt% or ≥ 97.80 wt% to ≤ 98.50 wt% or ≤ 98.40 wt% or ≤ 98.30 wt% or ≤ 98.20 wt% or ≤ 98.10 wt% or ≤ 98.00 wt% of silver.

[0017] For example, the alloy may contain, based on the total weight of the alloy, ≥ 0.75 wt% or ≥ 0.80 wt% or ≥ 0.85 wt% or ≥ 0.90 wt% or ≥ 0.95 wt% to ≤ 1.25 wt% or ≤ 1.20 wt% or ≤ 1.15 wt% or ≤ 1.10 wt% or ≤ 1.05 wt% of copper.

[0018] For example, the alloy may contain gold in an amount of ≥ 0.75 wt% or ≥ 0.80 wt% or ≥ 0.85 wt% or ≥ 0.90 wt% or ≥ 0.95 wt% to ≤ 1.25 wt% or ≤ 1.20 wt% or ≤ 1.15 wt% or ≤ 1.10 wt% or ≤ 1.05 wt%, based on the total weight of the alloy.

[0019] In a preferred embodiment, the alloy consists, based on the total weight of the alloy, of - ≥ 97.50 wt% to ≤ 98.50 wt%, for example up to ≤ 98.40 wt% or ≤ 98.30 wt%, silver, - ≥ 0.75 wt%, for example ≥ 0.80 wt% or ≥ 0.85 wt%, to ≤ 1.25 wt%, for example to ≤ 1.20 wt% or ≤ 1.15 wt%, copper and - ≥ 0.75 wt%, for example ≥ 0.80 wt% or ≥ 0.85 wt%, to ≤ 1.25 wt%, for example to ≤ 1.20 wt% or ≤ 1.15 wt%, gold.

[0020] Such an alloy composition has proven to be very advantageous for achieving a transparent, warm and luminous tone.

[0021] In a further preferred embodiment, the alloy consists, based on the total weight of the alloy, of - ≥ 97.80 wt% to ≤ 98.20 wt%, for example to ≤ 98.10 wt% or ≤ 98.00 wt%, silver, - ≥ 0.90 wt.%, for example ≥ 0.95 wt.%, to ≤ 1.10 wt.%, for example to ≤ 1.05 wt.%, copper and - ≥ 0.90 wt%, for example ≥ 0.95 wt%, to ≤ 1.10 wt%, for example to ≤ 1.05 wt%, gold.

[0022] Such an alloy composition has proven particularly advantageous for achieving a transparent, warm and luminous tone.

[0023] For example, the alloy can consist of 98 wt% silver, 1 wt% copper and 1 wt% gold.

[0024] In a further embodiment, the mass fraction of copper and the mass fraction of gold in the alloy are equal.

[0025] This has proven particularly advantageous for achieving a transparent, warm and luminous timbre.

For this purpose, reference is first made to the claims subordinate to claims 1 and 6. Preferred embodiments are explained in more detail below with reference to the drawings and the associated description, as well as the results of timbre analyses on various metals and metal alloys. The drawing shows: Fig. 1 shows a schematic representation of a sound reproduction system or an audio reproduction system with a loudspeaker, an amplifier and a sound signal source and illustrates a variety of possible uses of the alloy according to a variety of different possible embodiments of a respective use of the component according to the invention.

[0036] Fig. 1 shows an audio reproduction system with a loudspeaker 10, an amplifier 20 and a sound signal source 30, in which a silver-copper-gold alloy which - based on the total weight of the alloy - consists of ≥ 97.50 wt.% to ≤ 98.50 wt.% silver, ≥ 0.75 wt.% to ≤ 1.25 wt.% copper and ≥ 0.75 wt.% to ≤ 1.25 wt.% gold can be used in a variety of applications.

[0037] Fig.Figure 1 illustrates that the loudspeaker 10 has a loudspeaker housing 11. In particular, three loudspeaker chassis with three voice coils 12, 13, 14 are mounted in the loudspeaker housing 11. The aforementioned three voice coils 12, 13, 14 each have at least one electrical conductor, one of which can be formed from the alloy. For example, the silver-copper-gold alloy can be in the form of a voice coil wire, for example, with a diameter of approximately ≥ 0.1 mm to ≤ 2 mm.

Timbre analyses

[0050] To analyze the timbre of different metals and metal alloys, voice coils were fabricated from the metals or metal alloys under investigation 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 Nr. Silver [wt%] Copper [wt%] Gold [wt%] Timbre 1 100 warm, familiar 2 100 cool, transparent 3 99 1 less cool, transparent 4 98 2 narrow, throaty 5 97 3 narrow, throaty 6 98 1 1 transparent, warm, luminous

[0051] Table 1 shows that voice coil No. 1 made of copper resulted in a warm and familiar timbre, whereas voice coil No. 2 made of silver resulted in a cool and transparent timbre.

[0052] Voice coil No. 3, made of a silver-gold alloy of 99 wt% silver and 1 wt% gold, resulted in a transparent, but less cool, timbre than the silver voice coil No. 2. However, tests of voice coil No. 4, made of a silver-gold alloy of 98 wt% silver and 2 wt% gold, and voice coil No. 5, made of a silver-gold alloy of 97 wt% silver and 3 wt% gold, showed that increasing the gold content to 2 wt% and 3 wt%, respectively, resulted in a narrow, throaty timbre.

[0053] Finally, Table 1 shows that voice coil No. 6, made of a silver-copper-gold alloy of 98 wt% silver, 1 wt% copper and 1 wt% gold, surprisingly resulted in a transparent and at the same time warm and, in particular, bright timbre.

[0054] From the above statements it follows that different / various electrical, electronic and / or electrotechnical parts and / or electrical, electronic and / or electrotechnical components can have the above-mentioned silver-copper-gold alloy.
