Description

Technical Field

[0001] The present application relates to the technical field of terminal equipment, and in particular to a board noise suppression method, device, equipment, storage medium and program product. Background Art

[0002] Currently, users are more concerned about the power consumption of terminal devices. In order to save power, terminal devices will enter the discontinuous reception power saving mode (English: connected Mode DRx; abbreviated as: CDRx) during mobile communications. After entering the discontinuous reception power saving mode, the terminal device will periodically switch between the active state and the inactive state. In the active state, the terminal device will monitor the downlink channel for downlink reception, while in the inactive state, the terminal device will not monitor the downlink channel, that is, it will not receive downlink, thereby achieving the purpose of power saving. In actual applications, when the terminal device enters the discontinuous reception power saving mode, the large capacitor of the power supply will form a piezoelectric effect, which will cause the capacitor to vibrate. The sound of the capacitor vibration is transmitted to the earpiece, which will cause noise to the voice call. This is the board noise problem.

[0003] In the related art, in order to suppress board noise, the distance between the large capacitor of the power supply and the earpiece can be increased, thereby reducing the noise transmitted to the earpiece, thereby achieving suppression of board noise.

[0004] However, with the current trend of miniaturization of terminal devices, the space inside the terminal devices is extremely limited, which means that the distance between the large power capacitor and the earpiece cannot be very far. Therefore, the related technology suppresses board noise by increasing the distance between the large power capacitor and the earpiece, but the suppression effect of board noise is poor. Summary of the invention

[0005] Based on this, it is necessary to provide a board noise suppression method, device, equipment, storage medium and program product that can improve the board noise suppression effect in response to the above technical problems.

[0006] In a first aspect, the present application provides a board noise suppression method, comprising:

[0007] Detect whether the terminal device is in a discontinuous reception power saving working mode; if the terminal device is in the discontinuous reception power saving working mode, control the RF power management chip to enter a continuous working state so that the RF power management chip continuously outputs a voltage of a target level; wherein the RF power management chip is used to power a target device in a RF transmission link in the terminal device.

[0008] In a second aspect, the present application also provides a board noise suppression device, comprising:

[0009] A detection module, used to detect whether the terminal device is in a discontinuous reception power saving working mode;

In actual applications, after the terminal device enters the discontinuous reception power saving working mode, the RF power management chip will be periodically opened and closed, thereby forming a periodic high and low voltage output, and it is this periodic high and low voltage that causes the large capacitor of the power supply to form a piezoelectric effect, thereby causing capacitor vibration, and then bringing about a board noise problem. In the present application, when the terminal device is in a discontinuous reception power saving working mode, the RF power management chip can be controlled to continuously output a voltage of a target level. In this way, the RF power management chip will not form a periodic high and low voltage output, thereby avoiding the board noise problem at the source. Therefore, the board noise suppression effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] In order to save power, the terminal device will enter a discontinuous reception power saving working mode during mobile communication. After entering the discontinuous reception power saving working mode, the terminal device will periodically switch between an active state and an inactive state.

[0030] In the active state, the terminal device monitors the downlink channel for downlink reception, while in the inactive state, the terminal device does not monitor the downlink channel, that is, does not receive downlink. Since the terminal device does not receive downlink in the inactive state, the RF receiving link in the terminal device can enter the dormant state, thus achieving the purpose of power saving.

[0031] Generally speaking, the uplink transmission and downlink reception in the terminal device are synchronized. Therefore, in the inactive state, the RF transmission link of the terminal device will enter the sleep state synchronously with the RF reception link, and in the active state, the RF transmission link of the terminal device will enter the working state synchronously with the RF reception link.

[0032] Please refer to Figure 1 , which is an exemplary simplified schematic diagram of a radio frequency transmission link, Figure 1 In the figure, 101 indicates a transceiver, 102 indicates a radio frequency power management chip, 103 indicates a power amplifier, 104 indicates a filter, 105 indicates an antenna switch, and 106 indicates an antenna.

[0033] Among them, the transceiver 101 is connected to the RF power management chip 102 through the MIPI (English: Mobile Industry Processor Interface; Chinese: Mobile Industry Processor Interface) bus interface to control the RF power management chip 102. The RF power management chip 102 can power the power amplifier 103. The power amplifier 103 is used to amplify the power of the uplink signal output by the transceiver 101. The filter 104 is used for signal filtering, and the antenna switch 105 is used to select the working frequency band.

[0034] When the RF transmission link is in working state, the RF power management chip 102 is turned on to supply power to the power amplifier 103 , and when the RF transmission link is in sleep state, the RF power management chip 102 is turned off to stop supplying power to the power amplifier 103 .

[0035] From the above description, it can be seen that after the terminal device enters the discontinuous reception power saving working mode, the RF power management chip 102 will be periodically turned on and off, thereby forming a periodic high and low voltage output. The periodic high and low voltage will cause the large capacitor of the power supply to form a piezoelectric effect, thereby causing the capacitor to vibrate. The sound of the capacitor vibration is transmitted to the earpiece, which will cause noise to the voice call. This is the board noise problem.

[0036] In the related art, board noise is generally suppressed from a hardware perspective. For example, in one method, the distance between the large power supply capacitor and the earpiece can be increased to reduce the noise transmitted to the earpiece, thereby achieving suppression of board noise. In another method, the large power supply capacitor can be disassembled into small capacitors. For example, a 4.7uF 0402 capacitor can be disassembled into two 2.2uF 0201 small capacitors. The smaller the capacitance and package, the smaller the vibration and the lower the board noise. Therefore, the board noise can be suppressed. In yet another method, the gluing and windowing of the large power supply capacitor can be prohibited to suppress board noise.

[0037] However, there are many constraints on suppressing board noise from a hardware perspective, and the board noise suppression effect is poor. For example, for the first method mentioned above, under the current trend of miniaturization of terminal devices, the space inside the terminal device is extremely limited, which means that the distance between the large power capacitor and the earpiece cannot be very far. Therefore, the method of suppressing board noise by increasing the distance between the large power capacitor and the earpiece has a poor suppression effect on board noise. For the second method mentioned above, disassembling the large power capacitor into small capacitors can only alleviate the board noise problem, because any capacitor will vibrate after forming a piezoelectric effect, and there will be board noise problems. In addition, when the capacitance of the large power capacitor is large, in order to ensure the effective capacitance, it needs to be disassembled into many small capacitors, which greatly increases the circuit layout area. For the third method mentioned above, the prohibition of dispensing and window opening has many structural restrictions, and some terminal devices may not be able to meet them.

[0038] In view of this, an embodiment of the present application provides a board noise suppression method, which can effectively suppress board noise and improve the suppression effect of board noise. The board noise suppression method can be applied to a board noise suppression device, and the board noise suppression device can be implemented as part or all of a terminal device through software, hardware, or a combination of software and hardware. Among them, the terminal device can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart car-mounted devices, etc., and the portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. In the following method embodiments, the execution subject is explained as a terminal device. In the optional embodiments of the present application, the execution subject is specifically a transceiver in the terminal device.

[0039] In an exemplary embodiment, Figure 2 As shown, a board noise suppression method is provided, comprising the following steps. Among them:

[0040] Step 201: The terminal device detects whether it is in a discontinuous reception power saving working mode.

[0041] In a possible implementation, the terminal device may determine whether the terminal device enables the discontinuous reception power saving working mode through control information or configuration information sent by the network side.

[0042] In another possible implementation, the terminal device may determine whether the terminal device enables the discontinuous reception power saving working mode according to whether the radio frequency receiving link is periodically dormant.

[0043] Step 202: If the terminal device is in the discontinuous reception power saving working mode, the terminal device controls the RF power management chip to enter a continuous working state, so that the RF power management chip continuously outputs a voltage of a target level.

[0044] Among them, the RF power management chip is used to power the target devices in the RF transmission link in the terminal equipment, such as Figure 1 As shown, the target device may be a power amplifier in a radio frequency transmission link.

[0045] When the terminal device is in the discontinuous reception power saving mode, by default, the RF power management chip will be periodically turned on and off, resulting in periodic high and low voltage outputs. As can be seen from the above description, it is this periodic high and low voltage that causes the board noise problem.

[0046] In the embodiment of the present application, if it is in the discontinuous reception power saving working mode, the terminal device controls the RF power management chip to enter the continuous working state, that is, controls the RF power management chip to skip the sleep stage and keep it normally on. Since the RF power management chip is normally on, the RF power management chip will continue to output the voltage of the target level (high level). In this way, periodic high and low voltage outputs will not be formed, thereby causing the large capacitor of the power supply to form a piezoelectric effect, and the capacitor will not vibrate, thereby suppressing the board noise at the source.

[0047] In this embodiment, by controlling the RF power management chip to enter a continuous working state when the terminal device is in a discontinuous reception power saving working mode, the RF power management chip is enabled to continuously output a voltage of a target level, wherein the RF power management chip is used to power a target device in a RF transmission link in the terminal device. In actual applications, after the terminal device enters the discontinuous reception power saving working mode, the RF power management chip will be periodically switched on and off, thereby forming a periodic high and low voltage output, and it is the periodic high and low voltages that cause the large capacitor of the power supply to form a piezoelectric effect, thereby causing capacitor vibration, and then bringing about a board noise problem. In the present application, when the terminal device is in a discontinuous reception power saving working mode, the RF power management chip can be controlled to continuously output a voltage of a target level, so that the RF power management chip will not form a periodic high and low voltage output, thereby avoiding the board noise problem at the source, and therefore, the board noise suppression effect is better.

[0048] In addition, the board noise suppression method provided in the embodiment of the present application adopts a software control method. Compared with the hardware method, the software control method is not restricted by factors such as structure and internal space of the terminal device. Therefore, it has higher flexibility and does not need to change the hardware layout and hardware settings inside the terminal device. Therefore, the hardware overhead caused by changes in the hardware layout and hardware settings can be avoided. At the same time, it can also be better compatible with equipment that has been put on the market.

[0049] In one embodiment, Figure 3 As shown, step 201 includes steps 301 and 302. Among them:

[0050] Step 301: The terminal device detects whether it is operating under the target communication standard.

[0051] Among them, the target communication standard includes 4G communication standard and 5G communication standard.

[0052] Step 302: If the terminal device operates under the target communication standard, the terminal device executes a step of detecting whether it is in a discontinuous reception power saving operation mode.

[0053] In actual applications, generally only in 4G communication standards and 5G communication standards does the terminal device have a discontinuous reception power saving working mode, while in other communication standards, for example, 2G / 3G communication standards and WIFI communication standards, the terminal device does not have a discontinuous reception power saving working mode. Therefore, in an embodiment of the present application, the terminal device can first detect whether it is working under the target communication standard. If it is working under the target communication standard, it can further detect whether it is in a discontinuous reception power saving working mode. In this way, the terminal device can avoid blindly detecting whether it is in a discontinuous reception power saving working mode, thereby saving power consumption of the terminal device.

[0054] It should be pointed out that although the embodiments of the present application only list the target communication standards including 4G communication standards and 5G communication standards, with the development of communication technology, new communication standards may emerge. As long as the new communication standards support the discontinuous reception power saving working mode, they should be included in the target communication standards of the embodiments of the present application.

[0055] Furthermore, since in an embodiment of the present application, when the terminal device is in a discontinuous reception power saving working mode, the RF power management chip will enter a continuous working state, that is, the RF power management chip will skip the sleep stage and remain normally on. Therefore, compared with the default working mode of the RF power management chip that periodically opens and closes, it is bound to cause an increase in power consumption.

[0056] The embodiment of the present application has conducted a detailed study and analysis on this issue. After research and analysis, it is found that the RF power management chip entering a continuous working state will cause the terminal device to increase its power consumption by 0.6mA in an idle state, and will cause the terminal device to increase its power consumption by 4mA in a discontinuous reception power saving working mode. After converting the increased power consumption, it can be concluded that the RF power management chip entering a continuous working state will reduce the terminal device's flight time by 0.0018 days.

[0057] According to the above description, the increase in power consumption caused by the RF power management chip entering the continuous working state is relatively slight, and in the discontinuous reception power saving working mode, the main contribution to the reduction in power consumption comes from the RF receiving link, not the RF transmitting link. Therefore, although the RF power management chip entering the continuous working state will cause an increase in power consumption, the power saving of the discontinuous reception power saving working mode will still be guaranteed when the RF receiving link saves power. Therefore, the RF power management chip entering the continuous working state will not have a significant impact on the power saving effect of the discontinuous reception power saving working mode.

[0058] Although the increase in power consumption caused by the RF power management chip entering the continuous working state is relatively slight, and will not have a significant impact on the power saving effect of the discontinuous reception power saving working mode, the embodiment of the present application still provides the following two methods to alleviate the problem of increased power consumption caused by the RF power management chip entering the continuous working state. The two methods correspond to Figure 4 The embodiments shown and Figure 5 The embodiment shown.

[0059] In an exemplary embodiment, Figure 4 As shown, step 202 includes steps 401 and 402. Among them:

[0060] Step 401: The terminal device obtains a discontinuous reception cycle corresponding to a discontinuous reception power saving working mode.

[0061] The discontinuous reception cycle refers to the period during which the terminal device switches between the active state and the inactive state. The discontinuous reception cycle is a very important indicator in the discontinuous reception power saving working mode.

[0062] In an optional embodiment of the present application, the terminal device can obtain the discontinuous reception period from the control information or configuration information sent by the network side.

[0063] In an optional embodiment of the present application, the terminal device may obtain the discontinuous reception cycle from the configuration information of the discontinuous reception power saving working mode stored locally.

[0064] Step 402: The terminal device controls the radio frequency power management chip to enter a continuous working state according to the discontinuous reception cycle.

[0065] In practical applications, the range of the discontinuous reception cycle is between 10ms and 2560ms, which is converted into a frequency range of 0.4Hz-100Hz, while the frequency range that the human ear can hear is 20Hz to 20kHz. Therefore, in theory, there will be a critical point of the discontinuous reception cycle. If the discontinuous reception cycle is greater than the critical point, the frequency of the generated noise will exceed the frequency range that the human ear can hear. At this time, although the large capacitor of the power supply will vibrate, the sound of the vibration cannot be heard by the human ear.

[0066] Based on the above analysis, in an optional embodiment of the present application, the terminal device can obtain a discontinuous reception cycle, and determine whether to control the RF power management chip to enter a continuous working state according to the discontinuous reception cycle.

[0067] In an optional embodiment of the present application, if the discontinuous reception period is less than the first preset period threshold, it can be considered that the frequency of the noise does not exceed the frequency range that can be heard by the human ear. At this time, the terminal device can control the RF power management chip to enter a continuous working state to suppress the board noise. If the discontinuous reception period is greater than or equal to the first preset period threshold, it can be considered that the frequency of the noise exceeds the frequency range that can be heard by the human ear. At this time, the terminal device can control the RF power management chip to enter a normal working state, wherein the normal working state is the default working state corresponding to the current working mode of the terminal device. For example, the normal working state is a state in which the RF power management chip is periodically opened and closed, that is, at this time, the terminal device may not suppress the board noise.

[0068] Since the terminal device can selectively control the RF power management chip to enter a continuous working state according to the discontinuous reception cycle, it can be Figure 2 On the basis of the illustrated embodiment, power consumption is reduced to a certain extent. At the same time, the terminal device will not control the RF power management chip to enter a continuous working state only when the frequency of the noise exceeds the frequency range audible to the human ear. Therefore, it is possible to reduce power consumption while ensuring that the voice call of the terminal device is not affected by the board noise.

[0069] As mentioned above, since the frequency range that the human ear can hear is 20Hz to 20kHz, theoretically, as long as the discontinuous reception period is above 50ms (the frequency is less than 20Hz), the human ear cannot hear the noise. That is, theoretically, the critical point of the discontinuous reception period is 50ms.

[0070] However, actual tests have found that there is a difference between the switching frequency of the output voltage of the RF power management chip (the switching frequency is consistent with the frequency corresponding to the discontinuous reception period) and the frequency of the capacitor vibration. Therefore, the theoretical critical point described above is not accurate. After actual tests, it was found that when the discontinuous reception period exceeds 320ms, the human ear cannot hear the noise. Therefore, according to the results of actual tests, the critical point of the discontinuous reception period can be 320ms, or near 320ms. Accordingly, the first preset period threshold in the above text can be set to 320ms, and can be set to a duration whose difference with 320ms is less than the preset difference threshold.

[0071] In an optional embodiment of the present application, after the RF power management chip enters a normal working state, if the discontinuous reception cycle changes, the terminal device can determine whether the discontinuous reception cycle after the change is less than a second preset cycle threshold. If the discontinuous reception cycle after the change is less than the second preset cycle threshold, the terminal device can control the RF power management chip to switch from a normal working state to a continuous working state.

[0072] The changed discontinuous reception period is less than the second preset period threshold, indicating that the frequency of the currently generated noise is already within the frequency range audible to the human ear. Therefore, at this time, the terminal device can perform board noise suppression, that is, the terminal device can control the RF power management chip to switch from a normal working state to a continuous working state.

[0073] In an optional embodiment of the present application, the second preset cycle threshold is less than or equal to the first preset cycle threshold. For example, when the first preset cycle threshold is 320ms, the second preset cycle threshold may also be 320ms. Alternatively, the second preset cycle threshold may be less than 320ms. For example, in an optional embodiment of the present application, the second preset cycle threshold may be 160ms.

[0074] Setting the second preset cycle threshold to be smaller than the first preset cycle threshold can avoid a ping-pong effect near the first preset cycle threshold, that is, avoid frequent switching of the RF power management chip state near the first preset cycle threshold.

[0075] In one embodiment, Figure 5 As shown, step 201 includes steps 501 and 502. Among them:

[0076] Step 501: The terminal device detects whether it is in a voice call state.

[0077] In a possible implementation, the terminal device may obtain the distance between the human ear and the earpiece of the terminal device, and determine whether the terminal device is in a voice call state according to the distance.

[0078] In actual applications, terminal devices are generally equipped with distance sensors. Distance sensors are sensors based on infrared, ultrasonic, photoelectric and other principles that can detect the distance between an object and the sensor and output the distance value. Taking an infrared sensor as an example, it sends out an infrared signal and detects its return time, and calculates the distance between the object and the sensor based on the speed of light and the return time. If the object is closer, the return time is shorter and the distance value is smaller. If the object is farther away, the return time is longer and the distance value is larger.

[0079] The terminal device can detect the distance between the human ear and the earpiece according to the distance sensor arranged near the earpiece, and the terminal device can determine whether the distance is less than a preset distance threshold. If the distance is less than the preset distance threshold, it means that the human ear is close to the earpiece. At this time, it can be determined that the terminal device is in a voice call state. Otherwise, it is considered that the terminal device is not in a voice call state. In an optional embodiment of the present application, the preset distance threshold can be 13 mm.

[0080] In another possible implementation, the terminal device obtains service information of its currently performing communication service, and determines whether the terminal device is in a voice call state according to the service information.

[0081] Optionally, if the service information indicates that the terminal device is currently performing a VONR (voice communication through a 5G network) or VOLTE (voice communication through an LTE network) communication service, it can be determined that the terminal device is in a voice call state.

[0082] Step 502: If the terminal device is in a voice call state, the terminal device detects whether it is in a discontinuous reception power saving working mode.

[0083] From the above description, it can be seen that the board noise problem has a greater impact on voice calls, but has relatively little impact on other types of services of the terminal device. Therefore, in an embodiment of the present application, the terminal device can execute subsequent board noise suppression steps when it is in a voice call state, and does not execute subsequent board noise suppression steps when it is in a non-voice call state. In this way, power consumption can be reduced while ensuring the quality of voice calls.
