The utility model embodiment provides a kind of fingerprint module, as shown in Figure 1, Figure 2, in the fingerprint mould of the utility model
In group first embodiment, including fingerprint chip IC, wiring board（It is not shown in figure）And the first becket H1 and the second becket H2,
First becket H1 and the second becket H2 is set to fingerprint chip IC surrounding edge；Wiring board includes ground path, the first metal
Ring H1 connection ground paths are for conducting static electricity to ground；It second becket H2 connection lines plate and insulate with the first becket H1,
Fingerprint chip IC connects the impedance that the second becket H2 is used to detect the second becket H2.
Specifically, by the way that the first becket H1 and the second becket H2 is arranged, wherein the first becket H1 and traditional function
Similar ground connection conducting static electricity reduces signal interference.For second becket H2 for realizing vivo identification function, cardinal principle is profit
It can be changed with the variation of temperature with the impedance of metal.Here second can be calculated according to the normal temperature range of human body
The impedance ranges of becket H2, when finger pressing fingerprint module leads to fingerprint IC since true finger and prosthetic finger temperature are different
（Also referred to as fingerprint recognition chip, fingerprint chip IC）Detect that the impedance of the second becket H2 is different, when impedance is in the resistance of setting
It is determined as prosthetic finger when except anti-range, on the contrary then be true finger, fingerprint IC feeds back information to mainboard（That is wiring board circuit）
Do corresponding response.
As shown in Figure 1, further, the first becket H1 and the second becket H2 are split ring.First becket H1
It is concentric ring with the second becket H2, seam is equipped between the open end of the first becket H1 and the open end of the second becket H2
Gap.Specifically, according to the needs of design the first becket H1 and the second becket H2 can be set to the opening of non-close
The opening of ring, two split rings is oppositely arranged and there are gaps, and gap here can also be filled by megohmite insulant
To ensure beauty.
Further, the first becket H1 is identical as the second becket H2 sizes.Here can by the first becket H1 with
The concentric ring that second becket H2 is arranged concentrically, and its ring radius size is identical, the gap of two such split ring and open end
A closed ring can be collectively constituted.In addition the perimeter of two split rings may be set to be identical, and two split rings can be with
With certain point or a certain plane be symmetrical or mirror image setting.
As shown in Fig. 2, further, the first becket H1 and the second metal H2 rings are closed-loop.First becket H1
It is concentric ring with the second becket H2, the first becket H1 is placed on the inside of the second becket H2, and there are gaps for centre.Specifically
, can according to design need the first becket H1 and the second becket H2 are disposed as closed ring, and by two rings
It is set as concentric ring, is placed parallel according to inside and outside size, such as the first becket H1 is placed in the inside of the second becket H2,
First becket H1 can be placed in the outside of the second becket H2.There are gaps between two beckets, can pass through insulation
Gap between two beckets of substance is filled to ensure beauty.
Further, the first becket H1 and the second becket H2 is circular rings or rounded square ring.It here can root
According to needing to be designed, common can be circular rings or rounded square ring, also be sometimes elliptical ring.
Further, the second becket H2 is copper metal ring or silver metal ring.Specifically, the material choosing of the second becket H2
Selecting can select according to the requirement to temperature accuracy.Can certainly choose other temperature and impedance operator it is more obvious and
Stablize side material to be made, the first becket H1 can be identical as the material of the second becket H2, can also be different.
In addition, the utility model also provides a kind of electronic device, fingerprint module recited above may be used.
Further, electronic device includes handheld terminal.Specifically, the fingerprint module can be arranged on mobile phone, realize
Prosthetic finger discriminant function makes the safety higher of the functions such as unlocked by fingerprint, fingerprint payment.
