[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
audio signal transmission means. 0 [Prior Art] FIG. 3 is a view showing a wiring between a
conventional audio amplifier and a speaker. In the figure, (1) is an audio amplifier, (2) is a
speaker cable, and (3) is a speaker. FIG. 4 is a diagram showing input / output signal waveforms
of the conventional speaker cable (2), wherein (4) is an input signal waveform, and (5) is an
output signal waveform. Next, the operation will be described. The audio signal output from the
audio amplifier (1) travels through the speaker cable (2) to drive the speaker C3. The input signal
waveform (4) of the speaker cable (2) is output to the speaker (3) as the output of the speaker
cable (2) connected to the speaker (3) ([in the output signal waveform (5) Ru. [Problems to be
Solved by the Invention] The conventional speaker cable has an electric resistance, and the
response of the signal waveform supplied from the audio amplifier is tb as shown in FIG. 4, and
the signal of the audio amplifier is faithful to the speaker It is impossible to tell. In addition, there
is a problem that the reproduced sound depends on the length of the speaker cable and the
material thereof. The present invention has been made to solve the above-mentioned problems,
and its object is to faithfully transmit the signal of an audio amplifier to a speaker. [Means for
Solving the Problems] The speaker cable according to the present invention uses a
superconducting material as the material of the cable. [Operation] The speaker cable in the
present invention uses a superconducting material as a material, so that the electric resistance of
the speaker cable becomes zero, the transmission loss of the audio signal is eliminated, and the
signal waveform is faithfully transmitted. An embodiment of the present invention will now be
described with reference to the drawings. FIG. 1 is a diagram showing the wiring between the
audio amplifier and the speaker, and FIG. 2 is a diagram showing the input / output signal
waveform of the speaker cable (6). In the figure, since (1) to (5) are equivalent to those shown in
FIG. 2 of the conventional example, the description will be omitted. The speaker cable (6) uses a

superconducting wire as a material. Next, the operation will be described. The audio signal
output from the audio amplifier (1) faithfully travels through the superconducting speaker cable
(6) without breaking the signal waveform, reaches the speaker (3), and drives the speaker (3).
Also, when the superconducting speaker cable (6) loses superconductivity due to heat generation
and the resistance rises, a signal is transmitted through the conventional speaker cable (2)
connected in parallel. , Drive the speaker (3).
In the above embodiment, although the case of the speaker cable (6) (7) has been described, the
internal wiring of the audio amplifier (1) and the speaker (3), and the bin code connecting the OD
player and the audio amplifier (1) A room temperature superconducting material may be used as
the wire rod, and the same effect as the above embodiment can be obtained. As described above,
according to the present invention, since the audio signal transmission path is configured to have
zero electrical resistance, faithful waveform transmission can be performed, and the audio signal
transmission path is beautiful regardless of the length of the speaker cable. There is an effect
that the playback sound can be obtained.
