Abstract

(57) [Summary] [PROBLEMS] In a commercial power cord for a monaural audio device of a plurality of units and the same model number for constructing a conventional stereophonic sound system for stereo reproduction or the like, since each device is supplied with power from a separate power outlet, Despite the same model number device, a difference in sound quality was produced and the sense of three-dimensional sound field was hindered. SOLUTION: With a power cord having a plurality of outputs with one power plug, commercial power under the same conditions can be supplied to each monaural audio device constructing a three-dimensional audio system, and sound quality can be improved.

Description

[Detailed description of the invention]     [0001]   [Technical field to which the invention belongs]   The present invention relates to a commercial power cord for improving the sound quality of a three-dimensional sound system.     [0002]   [Prior art]   Multiple units and the same model number for building a stereophonic system such as conventional stereo playback There is one commercial power cord for monaural audio equipment, one for each equipment. As an example of improving the sound quality, it is common to replace the power cord with an appropriate power cord sold separately.   [Problems to be solved by the invention]   It is well known in recent years that the sound quality of commercial power outlets differs depending on the model number. Has become. In addition, there are two outlets per commercial power outlet. However, as a result of strict viewing, it was found that these two openings also had a difference in sound quality. this is, Regardless of the way the external line is connected to the commercial power outlet, It comes from the impossibility of the same conditional branch that is completely mentally and physically possible. in this way In the conventional method of supplying power to monaural audio equipment, , The difference in outlet openings prevents uniform sound quality, It has led to worsening.     [0003]   The present invention seeks to solve the problems of the conventional power cord. The sound quality of multiple monaural audio devices of the same model An object of the present invention is to improve the sound quality of an acoustic system.     [0004]   [Means for Solving the Problems]   Then, in order to achieve the above object, the present invention This is a commercial power cord that can supply power to the same type of monaural audio equipment.     [0005]   [Embodiment of the invention] An embodiment of the present invention will be described below with reference to FIGS.     [0006]   In FIG. 1, two power cords are connected to the electric wire connection portion of the commercial power plug 1, and An output connector 2 is attached to each of the other long ends.     [0007]   When it is difficult to insert a plurality of power cords 3 into the power plug 1, as shown in FIG. The short power cord 4 is connected to the commercial power plug 1 and the connection 5 for multiple branches To the required number of power cords. And each other end of the power cord 3 of the same length Each output connector 2 is attached.     [0008]   [Effect of the invention]   The multi-branch output type commercial power cord of the present invention can Power supply to the same model monaural audio equipment from separate power outlets. To avoid the deterioration of sound quality due to the conventional power supply system and supply commercial power under the same conditions. Therefore, it is possible to improve sound quality.
