Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most from start to finish
Same or similar label represents same or similar element or has the element of same or like function.Below with reference to attached
The embodiment that figure describes is exemplary, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.
The mobile terminal and printing board PCB thereof proposed according to embodiments of the present invention is described with reference to the accompanying drawings.
Fig. 1 is the block diagram of the printing board PCB of mobile terminal according to an embodiment of the invention.
As it is shown in figure 1, the printing board PCB of this mobile terminal includes: body 100, pronunciation component 110, L channel pass
Defeated line 120, R channel transmission line 130 and ground wire 140.
Wherein, the pronunciation component 110 on body 100 it is arranged on for exporting L channel acoustical signal and right channel sound
Signal.Being arranged on the left channel transfer line 120 on body 100 and R channel transmission line 130, left channel transfer line 120 is used for
Transmission L channel acoustical signal, R channel transmission line 130 is used for transmitting right channel sound signal, wherein, left channel transfer line 120
All being connected with pronunciation component 110 with one end of R channel transmission line 130, the other end of left channel transfer line 120 connects L channel
Speaker, the other end of R channel transmission line 130 connects right channel loudspeaker.It is arranged on the ground wire 140 on body 100, ground
Line 140 is arranged between left channel transfer line 120 and R channel transmission line 130, ground wire 140 in order to make L channel acoustical signal and
Right channel sound signal forms false differential signal.Wherein, left channel loudspeaker can be left ear earphone, and right channel loudspeaker is right
Ear earphone, the width of ground wire 140 can be 0.3-0.5mm, the such as width of ground wire 140 can be 0.4mm.
Specifically, as in figure 2 it is shown, after printing board PCB powers on, pronunciation component 110 exports L channel acoustical signal
With right channel sound signal, when L channel acoustical signal transmits in left channel transfer line 120, right channel sound signal is simultaneously
R channel transmission line 130 transmits, now, the L channel acoustical signal in left channel transfer line 120, and R channel transmission line
