Description
Technical field
The present invention relates to field of communication technology more particularly to mobile terminal winding structures.
Background technique
In general, when having the people of dysaudia using mobile phone needing that hearing aid is cooperated just to be made a phone call with mobile phone.The United States Federal is logical
Federal communications commission (Federal Communications Commission, FCC) enforces hearing aid for each manufacturer of mobile phone
The certification of compatible (Hearing Aid Compatibility, HAC), HAC reference standard be ANSI C63.19 (U.S. without
Line communication apparatus and hearing aid compatibility measure national standard method).Purpose is to allow the people for having dysaudia in wear hearing aid
When can normal use mobile phone make a phone call.HAC test is related to 2 compatibility coefficients " M " and " T ", wherein " M " is to be directed to
The compatibility that the microphone of hearing aid is answered, meaning are to judge that electric field strength and magnetic field strength are to microphone near hearing aid
It influences；" T " is the compatibility answered for the induction coil of hearing aid, i.e. T-coil test, representative is wireless device in sound
The magnetic field strength of frequency wave band measures.Have T grades a on hearing aid, the T-coil on hearing aid can be passed through when hearing aid selects this grade
Coil comes the magnetic field of coupling audio range, is then converted to electric signal and amplifies, to achieve the purpose that hearing aid.
There are two types of the technical solutions for realizing HAC T-coil at present: one is T-coil coil is integrated in receiver,
This receiver is called HAC receiver；Another kind is using the HAC inductance for having T-coil function, and HAC inductance and non-HAC are called
The T-coil function of HAC is realized in device cooperation.Both schemes have certain cost disadvantage.Wherein, HAC receiver is than non-HAC
The cost of receiver is much higher, and some high-end producer's types use the HAC receiver of customization, needs higher cost, in addition,
It becomes thin now with mobile phone and mobile phone top device layout is more and more, it is desirable that receiver encapsulation wants small and thickness is wanted
It is thin, and the T-coil coil turn built in the receiver of small package reduces, T-coil performance can be deteriorated, and at high cost.
More than some low side machines uses more is the scheme of HAC inductance and the cooperation of non-HAC receiver.Existing HAC inductance
Encapsulation is all very big, needs to occupy very big layout area and space in layout, often will appear the difficult problem of layout.HAC
Inductance and receiver, which are used cooperatively, has magnetic direction matching.If the patch direction of HAC inductance is malfunctioned, HAC inductance
Most probably there is the problem of reversely offsetting in the pole the N S in the magnetic field that the magnetic field and receiver that coil generates generate, at this moment T-coil index
It can severe exacerbation.And the problem once occurs, production line has no idea to detect.Therefore the current side of evading to the problem
Certain distance use that method is receiver and HAC inductance is staggered, such reverse magnetic field cancellation level can weaken, but whole in this way
Magnetic field strength will not be too strong.

Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
As shown in Figure 1, present pre-ferred embodiments provide a kind of system block diagram of mobile terminal winding structure, including printing
Circuit board (printed circuit board, PCB), the audio codec on PCB, receiver and coiling.
Wherein, audio codec, receiver and coiling are electrically connected.Coiling carried out by way of in PCB trace around
Circle, and the coiling can be in parallel with receiver, can also connect with receiver.In other embodiments, coiling can be with
It is operated alone, to realize the function of being similar to HAC inductance.
The audio codec and receiver of the present embodiment can use audio codec, the receiver of the prior art,
The application is not particularly limited.
Optionally, the number of turns of coiling, which can be single layer, can also make multilayer, and this embodiment is not specifically limited.
The mobile terminal of the application can be implemented in a variety of manners.For example, may include such as mobile phone, tablet computer,
Laptop, palm PC, personal digital assistant (Personal Digital Assistant, PDA), portable media are broadcast
It is mobile eventually to put device (Portable Media Player, PMP), navigation device, wearable device, Intelligent bracelet, pedometer etc.
End.
As shown in Fig. 2, the coiling on PCB can be laid out in the winding area in Fig. 2, it may be assumed that according to HAC T-
Coil testing standard is using receiver as the region of center 50mm × 50mm.
Optionally, coiling layout is in the lower section of receiver, so that the coil on receiver and PCB generates the same direction
Magnetic field strength achievees the effect that magnetic field strength mutually enhances.
As shown in figure 3, being the schematic diagram of single-layer winding circle.Coil generate magnetic field intensity and coil shapes and sizes without
Close, shape, the size of the coiling of the unlimited order layer of the present embodiment, can PCB according to actual needs cabling situation it is specific
Adjustment.
Optionally, the number of turns of single-layer winding circle also according to other cablings of the layer the case where, accomplish as far as possible The more the better, do not do
It is specific to limit.According to the calculation formula of coil magnetic field intensity:
H=N × I ÷ L,
Wherein, N is the number of turns of coil；I is electric current, and L is effective magnetic circuit length.According to above-mentioned formula, increase can be passed through
The number of turns N of coil increases the magnetic field strength H of coil with the electric current I in coil is improved.Coiling use multilayer winding, each layer around
Line can connect or parallel connection.
As shown in figure 4, each layer line circle for coiling is schematic diagram in parallel.In Fig. 4, coiling, audio coding decoding
Device and receiver are electrically connected.Wherein, coiling include first layer coil, second layer coil ..., n-th layer coil, and
One layer line circle, second layer coil ..., n-th layer coil be arranged in parallel.Since the coil impedance of each layer parallel connection is smaller, impedance is small
In ten ohm, in the present embodiment, winder is arranged in series with receiver.Assuming that the impedance of first layer coil is R1, n-th layer line
The impedance of circle is Rn, then impedance comparison is small after each layer coils from parallel connection of coils of PCB, and the more impedances of the number of plies are smaller.
As shown in figure 5, each layer line circle for coiling is concatenated schematic diagram.In Fig. 5, coiling, audio coding decoding
Device and receiver are electrically connected.Wherein, coiling include first layer coil, second layer coil ..., n-th layer coil, and
One layer line circle, second layer coil ..., n-th layer coil be arranged in series.Assuming that the impedance of first layer coil is R1, n-th layer coil
Impedance be Rn, then after the series connection of each layer line circle of PCB, impedance R1+R2+ ...+Rn, impedance is larger, leads to the electric current on coil
Become smaller, according to above-mentioned formula, magnetic field strength can also become smaller therewith, then coiling is arranged in parallel with receiver.In other embodiments
In, setting can also be operated alone in coiling with receiver.
Optionally, each layer line circle on coiling is either in parallel or series connection requires each layer line circle and to set with one heart
It sets, it is superimposed with the magnetic field for guaranteeing that each layer coiled wire-wound coil generates.
The mobile terminal winding structure of the application, T-coil function is realized by the coiling on PCB, is adopted with saving
With the cost of HAC receiver and the cost of additional HAC inductance component, patch directionality existing for additional HAC inductance is evaded and has asked
Topic, and can determine the direction of winding of PCB trace according to the direction of winding of the receiver of use, while saving and encapsulating greatly
Layout area shared by HAC inductance.
