Fig. 3 is the plane graph schematically showing the magnetic piece according to example embodiment.Implement according to example
The magnetic piece 100 of example can include the first magnetic component 111 and the second magnetic component 112.
First magnetic component 111 may be provided at the central authorities of magnetic piece 100, and the second magnetic component 112 can be
The outside of the first magnetic component 111 it is arranged on same layer.It is to say, the first magnetic component 111 He
Second magnetic component 112 can arrange on the same layer each other.
Additionally, the first magnetic component 111 and the second magnetic component 112 can have characteristic different from each other.
It is to say, the first magnetic component 111 and the pcrmeability of the second magnetic component 112, screen effect and
At least one in fissipation factor can be different from each other.
First magnetic component 111 can improve coil or the sky sending and/or receiving the signal with first frequency
Signal in line sends and receives characteristic, and the second magnetic component 112 can improve transmission and/or reception has ratio
Signal in the coil of the signal of the second frequency that first frequency is high or antenna sends and receives characteristic.First
Frequency can be the frequency for wireless power transmission according to wireless charging alliance (WPC) standard, root
According to the frequency sent for wireless power of power supply item alliance (PMA) standard or according to wireless charging
The frequency sent for wireless power of Electricity Federation alliance (A4WP) standard, second frequency could be for leading to
Believe the frequency of (such as, near-field communication (NFC)) or mark according to wireless charging alliance (A4WP)
The accurate frequency sent for wireless power.The frequency for wireless power transmission according to WPC standard can
To be 110kHz to 205kHz, according to the frequency for wireless power transmission of PMA standard can be
277kHz to 357kHz, the frequency for NFC can be 13.56MHz, according to A4WP standard
The frequency sent for wireless power can be 6.78MHz.
When there is metal etc. near the coil receiving low frequency high power signal (such as wireless power signal)
Time, vortex flow the loss caused can increase, when there is circuit arrangement near coil, and circuit arrangement
Also the appreciable impact of the signal (such as, field signal) that coil receives can be received through.Therefore, exist
In the case of coil receives low frequency high power signal (such as wireless power signal), for the magnetic of coil
Sheet need to have sufficiently large pcrmeability and screen effect with prevent magnetic field affect the metal neighbouring with coil or
Circuit.According in the magnetic piece of example embodiment, with to be provided with reception low frequency high power signal (all
Such as wireless power signal) coil corresponding region, region in arrange the first magnetic component 110 exist
80 or more up to 2000 or more can be had in the frequency range of 110kHz or more up to 205kHz or lower
Low pcrmeability, or can have 100 or the magnetic conductance of more up to 700 or lower in the frequency of 6.78MHz
Rate.
In the case of comprising the amorphous sheet of non-crystalline material, due to the architectural characteristic of material, pcrmeability and screen
It can be high for covering effect.It addition, along with the thickness of magnetic piece reduces, magnetic saturation reduces, but even if
In the case of amorphous sheet thickness reduces, amorphous sheet also can have high magnetic saturation.Therefore, according to showing
In the magnetic piece of example embodiment, receiving low frequency high power signal (such as wireless power signal) with being provided with
Coil corresponding region, region in arrange the first magnetic component 111 can comprise non-crystalline material.In detail
Say, the first magnetic component 111 can comprise Nb-Si, Ti-Nb-Si, Mo-Si, Zr-Si, Nb-Ti, Nb3Sn
Or V3Ga。
Generally, in the case of magnetic piece, along with pcrmeability increases, fissipation factor trends towards increasing.?
Coil receives the situation of the such as high-frequency low-power signal of communication (such as, near-field communication (NFC)) signal
Under, when the pcrmeability of magnetic piece increases, the loss in magnetic piece also increases, thus communication distance can subtract
Little.Therefore, for the high frequency sent with receive (such as, near-field communication (the NFC)) signal that such as communicates
The coil of low-power signal, needs the magnetic piece using the magnetic conductivity and low loss factor low.Real according to example
Execute in the magnetic piece of example, such as communicating (such as, near-field communication (NFC)) with being provided with to send and receive
The second magnetic component 112 arranged in the corresponding region, region of the coil of the high-frequency low-power signal of signal
Frequency at 13.56MHz can have 80 or the pcrmeability of more up to 300 or lower and 1 or bigger extremely
The fissipation factor of 20 or less.
In the case of comprising the ferrite sheet of Ferrite Material of sintering, pcrmeability is little, and during low frequency
The difference between pcrmeability and fissipation factor when pcrmeability and fissipation factor and high frequency is little.Therefore, at root
According in the magnetic piece of example embodiment, be provided with transmission and receiving and such as communicate that (such as, near field is logical
Letter (NFC)) signal high-frequency low-power signal coil corresponding region, region in arrange the second magnetic
Property component 112 can comprise the Ferrite Material of sintering.In detail, the second magnetic component 112 can comprise
Mg-Zn、Ni-Zn、Mn-Zn、SrFe12O19、BaFe12O19Or CoFe2O4。
Wireless power according to A4WP standard is characterised by that frequency is higher and power is the biggest.Therefore,
In the case of the wireless power that coil receives according to A4WP standard, can be according to the size Selection magnetic of coil
The material of property component.Such as, in the case of the radius of coil is little, say, that be arranged at coil
In the case of the corresponding region, region being provided with the first magnetic component 111, can use and comprise amorphous
The magnetic component of material, in the case of the radius of coil is big, say, that be arranged at coil and set
In the case of being equipped with in the corresponding region, region of the second magnetic component 112, the ferrum comprising sintering can be used
The magnetic component of ferrite.
Although Fig. 3 showing, the first magnetic component 111 is centrally disposed and the second magnetic component 112 sets
Put the situation in outside at the first magnetic component 111, but the first magnetic component 111 and the second magnetic component
The setting of 112 can carry out various change, as long as the first magnetic component 111 and the second magnetic component 112 are arranged
On mutually the same layer.It is to say, be arranged on arbitrary plane at the first magnetic component 111
Under conditions of on first area, the second magnetic component 112 is identical with the plane of the first magnetic component 111
Plane on be arranged on not overlapping with first area second area, the first magnetic component 111 and second
The setting of magnetic component 112 can carry out various change.
Fig. 4 is the plane graph schematically showing the magnetic piece according to example embodiment.Implement according to example
The magnetic piece 100-1 of example can include the first magnetic component 111-1, the second magnetic component 112-1 and the 3rd magnetic
Property component 113-1.
First magnetic component 111-1 may be provided at the central authorities of magnetic piece 100-1, the second magnetic component 112-1
First can be arranged on the layer identical with the layer of the first magnetic component 111-1 with the 3rd magnetic component 113-1
The outside of magnetic component 111-1, so that the second magnetic component 112-1 and the 3rd magnetic component 113-1 not that
This is overlapping.It is to say, the first magnetic component 111-1 to the 3rd magnetic component 113-1 may be provided at each other
On identical layer.
Additionally, the second magnetic component 112-1 and the 3rd magnetic component 113-1 can have and the first magnetic structure
The characteristic that part 111-1 is different.First magnetic component 111-1 can have with Fig. 3 described in the first magnetic structure
The characteristic that the characteristic of part 111 is identical, the second magnetic component 112-1 and the 3rd magnetic component 113-1 can have
