Abstract

PURPOSE:To insert parts, in which several kinds of metals are combined, into a sound circuit to faithfully approach a reproduced sound to an original sound by pasting together two or more sheets of different metal plates in series and conductively for being fixed to a sound equipment while pulling out lead wires from the metal plates on their both ends. CONSTITUTION:Different kinds of metal plates 3 to 6 are conductively pasted together to be connected to the parts of a sound equipment for pulling out lead wires 2 from their both ends. A basic construction of these parts for a sound equipment is made into one unit, a plurality of these are connected in parallel to be inserted into the sound circuit for composing the parts of an integrated sound equipment. Then, a metal having the thickness less than 1mm and a diameter less than 5mm is used for the metal plates 3 to 6, while a material of the metal plate 3 to 6 is properly selected from among indium, gold, white gold, copper, vanadium, lead and aluminium so as to faithfully approach a reproduced sound to an original sound.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a component inserted into the circuit of audio equipment including televisions and radios. [Prior Art] Generally speaking, audio equipment converts sound vibrations collected by a microphone into electrical signals. After passing through the air circuit, this device reproduces the sound vibrations again and listens to them with the ears. However, there are limits to the performance of the conversion components when collecting and converting the reproduced sound during playback, and as an electrical signal, it is subject to distortion by electrical circuit components in the high and low frequency ranges, making it difficult to reproduce it faithfully. It rarely happens. It is difficult to perfectly reproduce the original sound, so efforts have been made to reproduce it as close to the original sound as possible, and it has been reported that various improvements have been made to audio equipment parts such as speakers and electrical circuit parts such as capacitors. (Problem to be solved by the invention) However, even with these improvements, the reproduction is still not sufficient. Distortion caused by the materials of the parts and conductors in the audio equipment circuit cannot be ignored when the human ear hears the reproduced sound. This is probably due to the resonance phenomenon observed in the reproduced sound depending on the type of metal of the parts and conducting wires used in the circuit. [Means and actions for solving the problem] Eliminating this resonance phenomenon is the tenth solution.
By dispersing the resonance points, that is, by inserting parts made of several different types of metal into the audio equipment circuit, it is possible to make the reproduced sound faithfully approach the original sound. [Example] Figure 1 (a) shows the basic structure of this part (1). Different types of metal plates (3), (4). (5). (
6) are conductively bonded and bonded, and lead wires (2), (2) are drawn out from both ends. Figure 1(b)
is an example of this part. In the basic structure shown in Figure 1(a), the metal (3) is indium, the metal (4) is platinum,
After using copper as the metal (5) and panadium as the metal (6), these metal plates were crimped. Lead wires (2) and (2) (normal copper wire) are pulled out. This part can be used as is, but since it is a conductor, it was coated with insulating resin to prevent short circuits with other parts. This part is connected to the amplifier (11) and network (11) of the audio equipment circuit shown in Figure 3.
12) and listened to the playback sound and compared it with the case without inserting it, there was no resonance. The original sound was faithfully reproduced. In Fig. 3, (10) is a component for audio equipment according to the present invention, and (13) is a speaker. The second embodiment is shown in Figure 2. It is a composite part made by combining and connecting seven units in parallel, with the basic structure as one unit. In the figure (7) is the soldered part that is connected together.
(8) is the lead wire of the composite part. When we inserted the second composite component into the audio equipment circuit shown in Figure 3 and compared the reproduced sound before and after insertion, we were able to reproduce it more faithfully than in the first embodiment. In this example, the size of the metal plate is 0.1mmQ, and the diameter is 0.5mm.
It was made into a disk of mm. When the size, especially the thickness, of the metal plate is increased, a resonance effect appears in the metal plate used, making it pointless to use it, but it was effective with a thickness of 1 mm or less and a diameter of 5 mm or less. In addition, although a circular plate was used, it was not affected much by the shape; a rectangular plate,
Or it could be any other shape. Furthermore, in the examples, the metal material is indium, platinum, #! , vanadium was used, but combinations of various metals or alloys can be considered, and in addition to the above, gold, beryllium, lead, aluminum, etc. have been selected to be effective. In addition to a single metal plate, an alloy may also be used, and the use of alloys of the above metals was effective. Furthermore, although the metal plates were joined by crimping, cold welding, welding, or soldering may also be used. [Effect of the Invention J When the reproduced sound was compared between when the component according to the present invention was inserted into the audio equipment circuit shown in Figure 3 (lO shown in the figure) and when it was not inserted, there was a clear difference. ．． When the parts according to the present invention were inserted, there was no resonance in the reproduced sound, and the original sound was faithfully reproduced. Along with that, bass re-4. This also had the effect of improving the quality of the audio and increasing the resolution of the audio.
