Rice, and the thickness of flexible PCB 32 can be 0.08 millimeter.
Referring to Fig. 4, in one embodiment, one end of printed circuit board (PCB) 34 could be formed with breach 341, flexible electrical
Road plate 32 can be arranged in the breach 341.
Referring to Fig. 5, in one embodiment, the area of flexible PCB 32 can be with the area equation of breach 341.
That is, the bottom of flexible PCB 32 can align with the bottom of printed circuit board (PCB) 34.It should be noted that in Fig. 5 breach
Gap be present between flexible PCB 32 and printed circuit board (PCB) 34, the gap is only intended to distinguish flexible PCB and print in figure
Printed circuit board.And when implementing, flexible PCB can just fill the breach of printed circuit board (PCB).
Referring to Fig. 6, in another embodiment, the area of flexible PCB 32 can be more than the area of breach 341.
That is, the bottom of flexible PCB 32 can protrude from the bottom of printed circuit board (PCB) 34.
Referring to Fig. 7, the first pad 321 can be provided with some embodiments, on flexible PCB 32, and print
The second pad 341 can be provided with printed circuit board 34, then flexible PCB 32 and printed circuit board (PCB) 34 can pass through first
The pad 341 of pad 321 and second welds together.
For example, the quantity of the first pad set on flexible PCB 32 can be 4.Accordingly, printed circuit board (PCB) 34
The quantity of second pad of upper setting can also be 4.That is, the quantity of the second pad can be with the quantity of the 3rd pad
It is equal.
Referring to Fig. 8, the first sheet metal 322 can be provided with another embodiment, on flexible PCB 32, print
The second sheet metal 342 can also be provided with printed circuit board 34, the first sheet metal 322 and the second sheet metal 342 can pass through bullet
Piece 35 connects, so as to which flexible PCB 32 and printed circuit board (PCB) 34 be linked together.

Wind 31 can be by the 3rd pad solder on flexible PCB 32.It is understood that the quantity of the 3rd pad is at least
One.
In some embodiments, microphone 31 can be the microphone comprising power amplification circuit or not wrap
Microphone containing power amplification circuit.
It should be noted that microphone 31 is arranged on flexible PCB 32 in the present embodiment, due to flexible circuit
The thickness of plate is less than PCB hardboards, therefore is arranged on compared to by microphone on PCB hardboards, and voice signal exists in the present embodiment
Through hole is passed through by sound guide tube, this section of leading note transmission path for entering back into the acoustic aperture of microphone is reduced.Road is transmitted in leading note
In the case that footpath is shortened, voice signal quickly can enter in microphone.
As shown in figure 9, voice signal successively can pass through sound guide tube 36 and through hole 33, the acoustic aperture 312 of microphone is entered back into.Cause
This, is in the case where the path length of sound guide tube 36 is constant, because the thickness of flexible PCB is less than PCB hardboards, therefore it is soft
Property circuit board on the path length of through hole can be less than the path length of the through hole on PCB hardboards, it is therefore whole in the present embodiment
Leading note transmission path is reduced.
In the case where leading note transmission path shortens, voice signal is lost smaller in transmitting procedure.If using with active
The microphone of rate amplifying circuit, then microphone can receive more excellent voice signal.
In the case where leading note transmission path shortens, because voice signal quickly can enter in microphone, therefore this
Microphone in embodiment can also be the microphone without power amplification circuit, can so reduce Mike in electronic equipment
The cost of wind element.
