On the other hand, the noise flowing through the core 60 (62) during a call has a common mode and a differential mode (normal mode), the in-phase mode is the noise induced in each core 60 (62) The direction of is the same, and in the differential mode, the direction of noise induced in the wire is reversed. The cylindrical ferrite 96 effectively removes the differential mode noise. That is, the noise current flowing through the core wire is removed through the heating of the ferrite when passing through the cylindrical ferrite.

In addition, since the in-phase mode noise flowing through the core wires is adjacent to each other and passes through the ferrites 96 while flowing through the core wires 60 and 62 inserted together with the ferrite 96, the ferrite 96 passes through the core wires. It generates magnetic fields in different directions. That is, when current in the same direction flows, magnetic fields M1.M2 in opposite directions are generated in the core wires 60 and 62 wound in different directions. This magnetic field is dissipated by being bridged in the ferrite 96 because they are in different directions. After the extinction, the remaining noise is bypassed to the ground line 102 through the capacitors 98 and 100, thereby eliminating the noise in the in-phase mode.

After the call, the user removes the earphone 32 from the ear and presses the motor operation switch 82, the rotational force of the motor is transmitted to the driven gear 74 through the drive gear 92 and the protrusion 74a is roller.
