ア電線としたものを用い、電磁波を遮断している。2. Description of the Related Art It is necessary to block generation of noise due to electromagnetic waves in electric wires constituting a circuit connected to a speaker or the like. Therefore, twisted pair wires are used, which are formed by twisting a pair of wires forming a single circuit consisting of a wire connecting the power supply and the speaker and a wire connecting the speaker and the ground, to block electromagnetic waves.

When a wire is present, an electromotive force E is applied to the electric wire so that a current flows through directional arrows X1 and X2 that prevent a change in magnetic flux.
1, E2 occurs, and this becomes noise. On the other hand, as shown in FIG. 4B, when the electric wires w1 and W2 are twisted, the electromotive forces E1 and E2 generated by the magnetic flux density B become
Since current flows in the direction of canceling each other for one electric wire, the electromotive forces cancel each other, and therefore, no noise is generated.

That is, the electric wires w1 and w2 are made parallel,
Both ends of these electric wires are sandwiched between chucks C1 and C2, and the chuck C1 at one end is fixed, and the chuck C2 at the other end is rotated in the direction of the arrow, so that the electric wires w1 and w2 are rotated.
