[0035] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0036] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0037] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0038] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0039] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art will be able to readily implement many other equivalent forms of the present application.

[0040] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0041] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0042] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0043] The circuit boards of electronic devices have many circuits, and some of them will generate magnetic fields when working. If the user of the electronic device also uses other devices that are sensitive to magnetic fields and easily affected, then other devices will be disturbed when they are close to the electronic device.

[0044] Taking portable electronic devices (such as mobile phones and tablets) as an example, the circuits in portable electronic devices will generate magnetic fields when working, and some users will use devices that are sensitive to magnetic fields, such as hearing aids. The signals captured by hearing aids are generally within a frequency range, such as between 20Hz and 20kHz. Once the magnetic field generated by the portable device falls within the frequency range of the signal captured by the hearing aid, if the walking aid device is close to the portable device, the user using the hearing aid will hear noise, affecting the user experience.

[0045] An electronic device according to an embodiment of the present application, such as Figure 1 As shown, the device includes a body 1, a target component 2, a first component 3 and a second component 4.

[0046] The target component 2 is arranged on the body 1 and can be interfered by the magnetic field of the target frequency range when working. The first component 3 is arranged on the body 1 and connected to the first circuit; the second component 4 is arranged on the body 1 and connected to the second circuit.

[0047] The first circuit and the second circuit can generate a magnetic field within the target frequency range; the first circuit and the second circuit are at least partially parallel and generate opposite magnetic fields; and the distance between the first circuit, the second circuit and the target component 2 is less than a preset distance value.

[0048] Specifically, the target component 2 can be interfered with by the target frequency when it is working by itself, or when other devices are working close to the target component 2, and the device that can be interfered with by the target frequency is generally a device that needs to capture the signal of the target frequency and perform further processing. For example, when the electronic device is a mobile phone, the target component 2 is an earpiece, and the earpiece is located at the top center of the body 1. The hearing aid close to the earpiece can be interfered with by the magnetic field in the target frequency range.

[0049] The target frequency is the frequency at which the target component 2 may be interfered with. For example, if the target component 2 is an earpiece, when the earpiece is working, if the user wearing the hearing aid uses the earpiece, the target frequency range at which the hearing aid may be interfered with by the magnetic field is 20Hz-20kHz. If the frequency of the magnetic field generated by the first circuit and the second circuit is between 20Hz-20kHz, and the first circuit and the second circuit are at least partially parallel and generate opposite magnetic fields, then the magnetic fields generated by the first circuit and the second circuit can cancel each other out. When the user wearing the hearing aid uses the earpiece, the hearing aid will not capture the magnetic field, thereby avoiding interference of the first circuit and the second circuit on the hearing aid.

[0050] Among them, the line that can interfere with the target component 2 is generally a line whose distance is less than the preset distance value. This distance can be a line where there are points on the line that exceed the preset length and the distance from the target component 2 is less than the preset distance value. For example, the distance between each point of the line of 1cm and the target component 2 is less than the preset distance value. Therefore, the distance between the first line, the second line and the target component 2 in the present application is less than the preset distance value. For example, the preset distance value can be 50mm. When the distance between the first line, the second line and the target component 2 is less than 50mm, the magnetic field generated by the first line and the second line will interfere with the device close to the target component 2. Therefore, by offsetting the magnetic fields with each other through a parallel setting, the interference of the target component 2 can be reduced.

[0051] For example, a user wears a hearing aid while using a mobile phone to make a call. In traditional designs, some circuits in the mobile phone (such as the power circuit and the radio frequency circuit) may generate a magnetic field, which interferes with the normal operation of the hearing aid and causes the user to hear noise. After adopting the above design of the present application, the circuit inside the mobile phone is designed to generate opposite magnetic fields, which cancel each other out near the receiver, thereby reducing interference with the hearing aid.

[0052] The present application can significantly reduce the magnetic field interference to the device close to the target component 2 by generating the opposite magnetic fields through the first circuit and the second circuit. For example, reducing magnetic field interference can improve the comfort of hearing aid users, avoid noise caused by interference, enhance the compatibility between electronic devices (such as mobile phones) and hearing aids, and reduce the potential negative impact of electronic devices on hearing aids.

[0053] In one embodiment, the first circuit and the second circuit have periodic current changes with a target period, and can generate a magnetic field within the target frequency range.

[0054] Specifically, a periodically changing current will generate a periodically changing electric field, and the periodically changing electric field will continue to generate a periodically changing magnetic field. The frequency of the magnetic field is related to the changing period, and the strength of the magnetic field is related to the magnitude of the current change. Among them, the magnitude of the current of different circuits can determine the degree of magnetic field cancellation. When the magnitude of the current of the first circuit and the second circuit is the same, the degree of magnetic field cancellation is the largest.

[0055] For example, the target period (variation period) of the current or electric field can be set to 5 ms, corresponding to a magnetic field of 1 / 5*1000=200 Hz. Since the target frequency range is 20 Hz-20 kHz, the frequency of the magnetic field falls within the target frequency range.

[0056] That is, when an electronic device sends current with a period of 5 ms, a peak current with a period of 5 ms will appear on the power supply line of the electronic device, and this current generates a magnetic field noise of 200 Hz.

[0057] The first circuit and the second circuit have specific periodic current changes, and this periodic current will generate a magnetic field of a specific frequency. Because the magnetic fields generated by the first circuit and the second circuit are opposite, the parallel arrangement can offset each other near the target component 2 (earpiece), thereby reducing the magnetic field interference to the hearing aid.

[0058] In actual applications, when the electronic device is a mobile phone, the power circuit on the mobile phone will generate a magnetic field, which will generate noise on the hearing aid, thereby affecting the user experience of using the hearing aid.

[0059] Regarding the above content, Figure 1 As shown, the first circuit is respectively connected to the first component 3 and the second component 4; the second circuit is respectively connected to the first component 3 and the second component 4. The first component 3 is used to supply power to the second component 4.

[0060] Exemplarily, the target component 2 is a handset, the first component 3 is a battery connector, and the second component 4 is a chip. The first circuit and the second circuit are respectively connected to the first component 3 and the second component 4. The first circuit is a circuit for current to be supplied from the battery connector to the chip, and the second circuit is a circuit for current to flow back from the chip to the battery connector.

[0061] Even if the direction of current flow remains unchanged, but the first circuit and the second circuit have opposite directions, the current direction of the current flowing through the first circuit will be opposite to the current direction of the current flowing through the second circuit, that is, the current flows in opposite directions in the two circuits, thereby generating opposite magnetic fields, achieving mutual cancellation of the magnetic fields, thereby weakening the total noise magnetic field on the mobile phone and reducing external interference.

[0062] In one embodiment, if Figure 1 and Figure 2 As shown, the body 1 includes a carrier, and the carrier is used to carry and conduct electronic components. The first component 3 and the second component 4 are arranged on the carrier.

[0063] Specifically, the carrier is a part of the body 1, which is used to provide a platform or medium to install and fix electronic components while ensuring electrical connection between these components. The carrier can be a printed circuit board (PCB), a flexible circuit board (FPC) or other types of substrate materials, which are usually made of insulating materials and have conductive traces arranged thereon for transmitting electrical signals.

[0064] Correspondingly, a first circuit connected to the first component 3 and a second circuit connected to the second component 4 are also arranged on the carrier.

[0065] For example, the carrier is a PCB board, the first component 3 is a battery connector, and the second component 4 is a chip, then the battery connector and the chip are both arranged on the PCB board. Two circuits are arranged between the battery connector and the chip. When the chip is charged, the current is transmitted from the battery connector to the chip along the first circuit, and then flows back from the chip to the battery connector along the second circuit to form a loop. The first circuit and the second circuit constitute the loop, and the two circuits are parallel to each other, and the current directions of the currents on different circuits are opposite to each other, so as to generate magnetic fields with opposite magnetic field directions, and the magnetic fields with opposite magnetic field directions cancel each other out to reduce the total magnetic field of the electronic device.

[0066] In another embodiment, if Figure 2 As shown, the carrier includes a first carrier and a second carrier superimposed on each other, the first circuit is arranged on the first carrier, and the second circuit is arranged on the second carrier.

[0067] The carrier includes a first carrier and a second carrier superimposed on each other. This design is commonly seen in the construction of a multi-layer printed circuit board (PCB) in electronic devices. The first circuit and the second circuit can be arranged on different planes. When the two circuits are close to each other, the magnetic field cancellation effect can be improved, thereby helping to reduce magnetic field noise.

[0068] like Figure 2 As shown, the first circuit and the second circuit overlap in a direction perpendicular to the carrier. The first carrier is Layer 2, the first circuit is the area framed by the yellow line on Layer 2, the second carrier is Layer 3, the second circuit is the red solid area on Layer 3, and the two areas overlap in a direction perpendicular to the carrier.

[0069] Furthermore, when the first circuit and the second circuit are located on different carriers, the more similar their circuit lengths, widths and shapes are, the better the effect of canceling the magnetic fields they generate. Figure 3 It can be seen that when the routing method of the present application is adopted on the PCB board, the magnetic field corresponding to the routing position is significantly weakened.

[0070] Specifically, the first circuit and the second circuit overlap in a direction perpendicular to the carrier, which means that although the first circuit and the second circuit are located at different physical levels (i.e., different carriers), they have a certain correspondence in space. This design optimizes the circuit layout, can improve the magnetic field cancellation effect, and help reduce the generated magnetic field noise.

[0071] In one embodiment, if Figure 4 As shown, the device further includes a third component 5 and a fourth component 6. The first circuit is connected to the first component 3 and the third component 5 respectively; the second circuit is connected to the second component 4 and the fourth component 6 respectively; wherein the first circuit passes through the second component 4, and the second circuit passes through the first component 3, and the first circuit and the second circuit are parallel between the first component 3 and the second component 4.

[0072] In this embodiment, if the first line and the second line close to the target component 2 belong to lines between different components, that is, the first line is the line between the first component 3 and the third component 5, and the second line is the line between the second component 4 and the fourth component 6, the first line and the second line between the first component 3 and the second component 4 can be arranged in parallel so that the magnetic fields between the two lines cancel each other out. For example, the first line passes through the second component 4 and the second line passes through the first component 3, so that the first line and the second line generate parallel lines to achieve magnetic field cancellation.

[0073] Exemplarily, the first component 3 is a first RF power amplifier (PA1, Power Amplifie), the second component 4 is a second RF power amplifier (PA2, Power Amplifie), the third component 5 is a second power chip (QET2, Qualcomm Envelope Tracker), and the fourth component 6 is a first power chip (QET1, Qualcomm Envelope Tracker).

[0074] The RF power amplifier is responsible for amplifying the low-power RF signal to a sufficient power level so that it can be effectively transmitted to a long distance through the antenna. The first power chip and the second power chip can be a Qualcomm envelope tracker, which is used to dynamically adjust the power supply voltage of the RF power amplifier to improve the efficiency and performance of the power amplifier.

[0075] The first circuit includes a portion of the circuit between the second power chip and the second RF power amplifier and a portion of the circuit between the second RF power amplifier and the first RF power amplifier, and the second circuit includes a portion of the circuit between the first power chip and the first RF power amplifier and a portion of the circuit between the second RF power amplifier and the first RF power amplifier. Part of the first circuit between the second RF power amplifier and the first RF power amplifier and part of the second circuit between the second RF power amplifier and the first RF power amplifier are parallel to each other.

[0076] That is, the second power chip is connected to the first RF power amplifier through the first line to realize power supply to the first RF power amplifier, wherein the first line passes through the second RF power amplifier. The first power chip is connected to the second RF power amplifier through the second line to realize power supply to the second RF power amplifier, wherein the second line passes through the first RF power amplifier. In this way, the first line and the second line generate parallel lines.

[0077] In the parallel line portion, the current on the first line is transmitted to the first RF power amplifier along the second RF power amplifier, and the current on the second line is transmitted to the second RF power amplifier along the first RF power amplifier. That is, the current directions of the parallel line portions are opposite, and magnetic fields with opposite magnetic field directions can be generated to cancel each other out.

[0078] In the present application, the area within the preset distance value close to the target component 2 on the body 1 can be set as the interference area, and the other areas can be set as the non-interference area. At this time, the routing area of ​​the overlapping part of the first line and the second line (that is, the first line and the second line between the first RF power amplifier and the second RF power amplifier) ​​is set in the interference area, and the first line and the second line generate parallel lines to achieve magnetic field cancellation.

[0079] The routing area of ​​the non-overlapping portion of the first line and the second line (i.e., part of the second line between the first power chip and the first RF power amplifier, and part of the first line between the second power chip and the second RF power amplifier) ​​is located in the non-interference area. This part of the first line and this part of the second line will also generate a noise magnetic field, but they are located in the non-interference area, far away from the earpiece, so the noise magnetic field falling in the earpiece area is also relatively small.

[0080] Among them, part of the second line between the first power supply chip and the first RF power amplifier, and part of the first line between the second power supply chip and the second RF power amplifier can be set to any form, for example, a curve or a straight line shape, as long as it meets user needs, without considering the influence of the magnetic field generated by this part of the line.

[0081] In another embodiment, the loop for current flowing back from the first RF power amplifier to the second power chip and the loop for current flowing back from the second RF power amplifier to the first power chip are arranged in the non-interference area. The two loops also generate magnetic fields, but they are far away from the earpiece, so that the magnetic field generated by them hardly affects the earpiece.

[0082] In practical applications, such as Figure 5 As shown, conventional mobile phones are half-board designs, with the motherboard in the upper part of the mobile phone and the battery in the lower part. This design allows the battery capacity to be larger than the solution where the motherboard is designed as a side strip board or a C-shaped board. The battery and the motherboard are buckled onto the battery connector 8 of the motherboard through the battery FPC to power the motherboard.

[0083] At present, fast-charging batteries are usually designed with two battery connectors 8 in order to increase the charging input current and achieve fast charging. In addition, the upper frame of the mobile phone contains multiple antennas, so placing the RF front-end chip as close to the antenna as possible is conducive to improving RF performance, that is, placing the RF power amplifier close to the antenna area in the upper left corner, shortening the distance between the RF power amplifier and the antenna, reducing the RF front-end loss, and improving the transmission power.

[0084] However, such a design will make the power line close to the earpiece area, so that the magnetic field noise generated by the power line will affect the use of other devices. Therefore, the RF power amplifier is placed in an area far away from the earpiece, but the RF power amplifier is far away from the antenna, which will sacrifice RF performance.

[0085] Regarding the above content, Figure 6 As shown, the device also includes a fifth component 7, the first circuit is connected to the first component 3 and the fifth component 7 respectively; the second circuit is connected to the first component 3 and the second component 4 respectively; the second circuit is parallel to part of the first circuit.

[0086] In this embodiment, the first line and the second line close to the target component 2 are connected to the same devices, that is, the first line is the line between the first component 3 and the fifth component 7, and the second line is the line between the first component 3 and the second component 4. When setting the lines, the second line can be set parallel to the first line, such as, the first line is set through the second component, so that the first line is partially set between the first component 3 and the second component 4, parallel to the second line.

[0087] The fifth component 7 is used to supply power to the first component 3, the first component 3 is used to supply power to the second component 4, and the second component 4 is used to amplify radio frequency power.

[0088] Exemplarily, the first component 3 is a power management device (PAPM, Power Amplifier Power Management), the second component 4 is a radio frequency power amplifier (PA, Power Amplifie), and the fifth component 7 is a battery. The device also includes an antenna, which is arranged on the frame of the body 1, and the radio frequency power amplifier is close to the antenna. The device also includes a battery connector 8.

[0089] Specifically, the battery connector 8 is placed in the back area of ​​the RF power amplifier, the first line includes part of the line between the battery and the battery connector 8 and part of the line between the battery connector 8 and the power management device, and the second line includes the line between the power management device and the RF power amplifier. Part of the first line between the battery connector 8 and the power management device and the second line between the power management device and the RF power amplifier are parallel to each other.

[0090] In the parallel line portion, the current on the first line is transmitted to the power management device along the battery connector 8, and the current on the second line is transmitted to the RF power amplifier along the power management device. That is, the current directions of the parallel line portions are opposite, and magnetic fields with opposite magnetic fields can be generated to cancel each other out.

[0091] Therefore, the RF power amplifier is powered by the power management device, and the current flows from the lower right to the upper left; the power management device is powered by the battery, and the current flows from the upper left to the lower right. The two power lines are in opposite directions, and the magnetic fields they generate can be partially offset, thereby reducing the magnetic field noise in the earpiece area.

[0092] In the present application, the area within the preset distance value close to the target component 2 on the body 1 can be set as the interference area, and the other areas can be set as the non-interference area. At this time, the routing area of ​​the overlapping part of the first line and the second line (part of the first line between the power connector 8 and the power management device, and the second line between the power management device and the RF power amplifier) ​​is set in the interference area, and the first line and the second line generate parallel lines to achieve magnetic field cancellation.

[0093] The routing area of ​​the non-overlapping part of the first line and the second line is set in the non-interference area. For example, the battery connector 8 is connected to the FPC from the left side of the battery. This part of the first line will also generate a noise magnetic field, but it is set in the non-interference area and is far away from the earpiece. Therefore, the noise magnetic field falling in the earpiece area is relatively small.

[0094] Part of the first line between the battery and the battery connector 8 can be set to any form, for example, a simple straight line can be used to route the line, as long as it meets user needs, and there is no need to consider the influence of the magnetic field generated by this part of the line.

[0095] This application adjusts the power supply layout to reduce the noise magnetic field generated by the power supply while meeting the RF performance, thereby improving the HAC test indicators.

[0096] An embodiment of the present application further provides an electronic device, including a processor and a memory, wherein an executable program is stored in the memory, and the processor executes the executable program.

[0097] The processor may be a general purpose processor, a digital signal processor, an application-specific integrated circuit (ASIC), a programmable logic device (PLD) or a combination thereof. The PLD may be a complex programmable logic device (CPLD), a field-programmable gate array (FPGA), a generic array logic (GAL) or any combination thereof.
