However, the terminal is not always under the worst working condition of the sound playing device in the using process, and under such a condition, the playing sound effect of the sound playing device is affected due to the over-small flow limiting value of the sound playing device, so that the experience of the user is reduced.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are only a subset of the embodiments of the present disclosure, and not all embodiments. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

The sound playing device is used as a power consumer of the terminal system, and with the gradual popularization of the terminal double sound playing device and the flat four sound playing device scheme, the power consumption of the terminal is greatly increased. However, since the power supply technology of the terminal is not significantly improved, the maximum current that can be provided by the terminal is within a certain range (for example, 10A), which may cause the current to exceed the maximum current that can be provided by the power supply of the terminal when the dual sound playing device or the quad sound playing device operates simultaneously, thereby causing a power failure of the terminal system.

FIG. 1 is a flow chart of a current power management method.

As shown in fig. 1, in the related art, in order to prevent the terminal system from power-down, it is necessary to forcibly limit the current value usable by the audio playback apparatus. For convenience of explanation, the current value usable by the audio playback apparatus is limited to the current range supplied by the power supply a, and the current value usable by the other power consuming components is limited to the current range supplied by the power supply B. In the application process, the sound playing device can be in the worst working condition (the working conditions that other power consuming components except the sound playing device are in the maximum power consuming state), and the maximum current value (the current provided by the power supply a) of the sound playing device, which can be borne by the power supply of the terminal, is taken as the current limiting value of the sound playing device. However, the terminal is not always in the worst working condition of the sound playing device during the use process. Under such a condition, if the current limit value of the audio playing apparatus is too small, all the situations of the terminal operation require that the power consumption of the audio playing apparatus does not exceed the determined current limit value, which will result in that the current limit value of the audio playing apparatus will be too small when other power consuming components of the terminal system are in a normal operating state or an inoperative state, for example, only the audio playing apparatus is operating and other power consuming components are not operating. Further, the playing sound effect of the sound playing device is affected, which causes the experience of the user to be reduced.

The power supply management method provided by the disclosure determines a first current limiting value matching the current power consumption state of the terminal, and dynamically adjusts the current limiting value of the sound playing device based on the first current limiting value. Because different power consumption states correspond to different current limiting values of the sound playing device, a first current limiting value matching the current power consumption state of the terminal is determined, and the current limiting value of the sound playing device is dynamically adjusted based on the first current limiting value, the current limiting value of the sound playing device can be ensured to always correspond to the current power consumption state of the terminal, the dynamic adjustment of the current limiting value of the sound playing device is realized, the playing sound effect of the sound playing device in different power consumption states of the terminal can be ensured, and the experience of a user in the using process is improved.

FIG. 2 is a flow diagram illustrating a method of power management according to an example embodiment. The power management method is applied to a terminal, wherein at least one sound playing device is installed in the terminal. In one example, the sound playing devices may be speakers, and the terminal mounted with at least one sound playing device may be a mobile terminal or a tablet computer with one speaker, a mobile terminal or a tablet computer with two speakers, or a mobile terminal or a tablet computer with four speakers.

The present disclosure will explain a power management method by taking an example in which a plurality of sound playback devices are mounted on a terminal.

In an exemplary embodiment of the present disclosure, as shown in fig. 2, the power management method includes steps S11 and S12, which will be described separately below.

In step S11, the current power consumption state of the terminal is determined in response to the plurality of sound reproducing apparatuses being in the operating state. Wherein, different power consumption states correspond to different current limiting values of a plurality of sound playing devices.

In one example, when detecting that a plurality of sound playing devices are in an operating state, determining the current power consumption state of the terminal. Wherein the power consumption state of the terminal may be determined according to power consumption components operated by the terminal. In one embodiment, when the plurality of audio playback devices are in an operating state, and the terminal is capable of simultaneously operating power consuming components such as a Global System for Mobile Communications (GSM) rf power amplifier, a screen with maximum brightness adjustment, a flash lamp, and a reverse charging power consuming component, the power consuming state of the terminal is referred to as a power consuming state a. When the terminal can simultaneously operate power consumption components such as a screen and a flash lamp with the maximum brightness under the condition that the plurality of sound playing devices are in the operating state, the power consumption state of the terminal is called a power consumption state B.

In one embodiment, the current power consumption state of the terminal may also be determined according to the power consumption components currently operated by the terminal.

In the application process, in order to ensure that the power supply of the terminal system does not generate power failure, under different power consumption states of the terminal, the current values which can be used by the plurality of sound playing devices need to be limited, and the maximum peak current which can be used by the sound playing devices under the power consumption state is used as the current limiting values of the plurality of sound playing devices under the power consumption state. As can be seen from the above description, the current limit values of the plurality of audio playback devices corresponding to the power consumption state a are different from the current limit values of the plurality of audio playback devices corresponding to the power consumption state B.

In step S12, a first current limit value matching the current power consumption state is determined, and the first current limit value is adjusted to the current limit values of the plurality of sound reproducing apparatuses.

In one example, a first current limit value that matches a current power consumption state of the terminal may be determined based on the current power consumption state. It can be understood that, if the current power consumption state of the terminal changes, the first current limiting value matching the current power consumption state also changes correspondingly. The first current limit value may be a maximum peak current that can be used by a plurality of sound playing devices operated by the terminal when the terminal currently operates with one or more power consuming components and the power supply of the terminal system is not powered down. In the application process, the current limiting values of the plurality of sound playing devices can be adjusted to be the first current limiting value, so that the current power consumption states of the plurality of sound playing devices correspond to the current power consumption values of the terminal, the sound playing effect of the plurality of sound playing devices in different power consumption states of the terminal is ensured, and the experience of a user in the using process is improved.

The power management method provided by the disclosure responds to the fact that the sound playing device is in the running state, determines the current power consumption state of the terminal, determines a first current limiting value matched with the current power consumption state of the terminal, and dynamically adjusts the current limiting value of the sound playing device based on the first current limiting value. The different power consumption states correspond to different current limiting values of the sound playing device, the first current limiting value matching the current power consumption state of the terminal is determined, the current limiting value of the sound playing device is dynamically adjusted based on the first current limiting value, the current limiting value of the sound playing device can be guaranteed to be corresponding to the current power consumption state of the terminal all the time, dynamic adjustment of the current limiting value of the sound playing device is achieved, the sound playing effect of the sound playing device in the different power consumption states of the terminal can be guaranteed, and the experience of a user in the using process is improved.

The present disclosure will explain a process of determining a first current limit value matching a current power consumption state by the following embodiments.

In an exemplary embodiment of the disclosure, the power consumption states may include a first number of preset power consumption states, where each type of preset power consumption state corresponds to a respective preset current limiting value. It can be understood that the preset current limit value may be a maximum peak current that can be used by a plurality of sound playing devices operated by the terminal when the terminal is in a preset power consumption state and the power supply of the terminal system is not powered down.

It is understood that the preset power consumption state may be adjusted according to actual conditions, and in the present disclosure, the preset power consumption state is not specifically limited. In one embodiment, the power consumption state of the terminal can be divided into three types, namely, a high power consumption state, a medium power consumption state and a low power consumption state. On the premise that a plurality of sound playing devices operate, the high power consumption state can correspond to the power consumption states of a Global System for Mobile Communications (GSM) radio frequency power amplifier, a screen with the maximum brightness, a flash lamp and a reverse charging power consumption component, which are operated by a terminal simultaneously. Under the premise that a plurality of sound playing devices operate, the medium power consumption state can correspond to the power consumption state of a screen with the maximum brightness adjusted by a terminal simultaneously operating a Global System for Mobile Communications (GSM) radio frequency power amplifier. Under the premise that a plurality of sound playing devices operate, the medium power consumption state can correspond to the power consumption state of a screen with the minimum brightness adjusted when the terminal operates. It can be understood that the preset current limiting value corresponding to the high power consumption state, the preset current limiting value corresponding to the medium power consumption state, and the preset current limiting value corresponding to the low power consumption state may be different from each other.

In an embodiment, if the current power consumption state of the terminal is the same as a first preset power consumption state in the preset power consumption states, a preset current limiting value corresponding to the first preset power consumption state may be used as a first current limiting value matching the current power consumption state, and the current limiting values of the plurality of sound playing devices are adjusted based on the first current limiting value. In one example, if the current power consumption state of the terminal is the same as the low power consumption state, the preset current limit value corresponding to the low power consumption state may be used as a first current limit value matching the current power consumption state, and the current limit values of the plurality of audio playback devices may be adjusted based on the first current limit value. By the method, the sound effect played by the sound playing devices in the low power consumption state of the terminal can be ensured, and the experience of a user in the using process is improved.

It can be understood that the power consuming components operated by the terminal will affect the power consuming state of the terminal, and further affect the current limiting values of the plurality of sound playing devices in the power consuming state. The present disclosure will explain another process of determining the first current limit value matching the current power consumption state by the following embodiments.

In an exemplary embodiment of the present disclosure, the power consumption state includes a power consumption state of one or more other power consuming components different from the sound playing apparatus. Wherein determining the first current limit value matching the current power consumption state may be performed with reference to the process shown in fig. 3.

In one embodiment, as shown in fig. 3, the process of determining the first current limit value matching the current power consumption state may include steps S21 and S22. The steps will be described separately below.

In step S21, the operating state of one or more other power consuming components other than the sound playing device is determined.

In step S22, a first current limit value that matches the current power consumption state is determined based on the operating states of other power consuming components.

In one embodiment, the operational status of one or more other power consuming components currently operating on the terminal other than the sound playing device may be determined. The current power consumption state of the terminal is influenced by the running state of one or more other power consumption components, so that the current limiting values of the plurality of sound playing devices are influenced. Therefore, the first current limit value matching the current power consumption state can be determined based on the operation states of other power consumption components, and the current limit values of the plurality of sound playing devices can be adjusted based on the first current limit value. The first current limiting value is adapted to the current power consumption state formed by other power consumption components currently running in the terminal, the playing sound effect of the plurality of sound playing devices in different power consumption states of the terminal is ensured, and the experience of a user in the using process is further improved.

The present disclosure will explain a process of determining a first current limit value matching a current power consumption state based on the operation states of other power consumption components by the following embodiments.

In an exemplary embodiment of the present disclosure, in response to a target power consuming component among the one or more other power consuming components, a first current limit value matching a current power consuming state may be determined based on a first peak current of the plurality of sound playing devices and a second peak current corresponding to each of the one or more first power consuming components. Wherein, the target power consumption component is one or more first power consumption components which are not in an operation state and exist in one or more other power consumption components. The first peak current may be a maximum peak current corresponding to the plurality of sound emitting devices when one or more other power consuming components are each operating at the second peak current. The second peak current may be a maximum peak current for the first power consuming component alone operating at maximum power.

In a possible embodiment, the determining of the first current limit value matching the current power consumption state is performed based on the first peak currents of the plurality of sound playing apparatuses and the second peak currents corresponding to the one or more first power consumption components, and may be performed in the following manner: the sum of the first peak current and the second peak current corresponding to each of the one or more first power consuming components may be used as the first current limiting value matching the current power consuming state.

FIG. 4 is a flow diagram illustrating another method of power management in accordance with an exemplary embodiment.

In an example, as shown in fig. 4, a process of the power management method will now be described by taking a terminal having multiple sound playing devices, for example, a mobile terminal having multiple speakers, as an example.

In one possible embodiment, the power consuming components of a mobile terminal with multiple speakers are now classified into six categories, namely: 1. a loudspeaker public address (also called loudspeaker PA for short) system; 2. a GSM radio frequency power amplifier (also called GSM radio frequency PA); 3. a screen; 4. flash/flashlight; 5. a reverse charging member; 6. other power consuming components of the end system. It will be appreciated that each of the power consuming components described above may be the first power consuming component described above.

In one example, the maximum supply current of the mobile terminal system may be 10A. And adjusting other power consumption components except the horn PA to a maximum power consumption state, opening the horn PA, and adjusting the usable current of the horn PA from small to large on the premise that the power supply of the mobile terminal system is not powered off (or the mobile terminal system works normally) until the peak current Amax of the horn PA is reached. And storing the peak current Amax as a first peak current (maximum current limit value) of the horn PA in the memory of the mobile terminal. It can be understood that the first peak current Amax is a current limiting value of the horn PA when the mobile terminal is in a state of maximum power consumption.

Further, the maximum peak currents corresponding to the first power consuming components such as the GSM rf PA, the screen, the flashlight/flashlight, the reverse charging component, and the like, which operate independently at the maximum power, may be respectively tested as Bmax, Cmax, Dmax, and Emax, and the maximum peak currents are defined as the second peak currents and stored in the memory of the mobile terminal.

In an example, a first current limit value matching a current power consumption state may be determined based on a first peak current of the horn PA and a second peak current corresponding to each of the first one or more power consumption components. In one embodiment, when the first power consuming components operated by the mobile terminal are the GSM rf PA and the screen, and the flash is turned off and the reverse charging component is turned off, the first current limit value a matching the current power consuming state is Amax + Dmax + Emax. Further, the current limiting value of the horn PA is adjusted according to the first current limiting value A matched with the current power consumption state, namely Amax + Dmax + Emax, so that the current limiting value of the horn PA can be adjusted in real time according to the running condition of the current power consumption component of the mobile terminal, and the playing sound effect of the horn PA in the scene is improved. For example, if the mobile terminal is currently listening to music using the speaker PA, the playing sound effect of the speaker PA formed based on the current determined current limit value of the speaker PA is significantly improved compared to the playing sound effect of the speaker PA when the mobile terminal is in a high power consumption state.

The present disclosure will explain another process of determining a first current limit value matching a current power consumption state based on the operation states of other power consumption components by the following embodiments.

In an exemplary embodiment of the present disclosure, in response to all of the one or more other power consuming components being in an operating state, the first peak current of the plurality of sound playing devices may be determined as a first current limit value matching the current power consuming state. The first peak current may be a maximum peak current corresponding to the plurality of sound playing apparatuses when one or more other power consuming components all operate at a second peak current, and the second peak current may be a maximum peak current corresponding to the first power consuming component operating at a maximum power alone.

The process of the power management method will be described by taking the mobile terminal with multiple speakers as an example.

In an example, when power consuming components (a horn PA, a GSM rf PA, a screen, a flashlight/flashlight, a reverse charging component, and other power consuming components of a terminal system) of a mobile terminal with multiple horns are all in an operating state, a first peak current Amax of the horn PA may be directly used as a first current limiting value matching a current power consuming state, and a current limiting value of the PA is adjusted based on the first current limiting value. The current limiting value of the loudspeaker PA can be adjusted in real time according to the current running power consumption component of the mobile terminal, and the loudspeaker PA playing sound effect is improved on the premise that the power supply of the mobile terminal system is not powered off.

To further illustrate the inventive concepts of the present disclosure, the present disclosure will illustrate the overall process of the power management method by the following examples.

In an exemplary embodiment of the present disclosure, the process of the power management method is described by taking the mobile terminal with multiple speakers as an example.

As shown in fig. 5, the power management method includes steps S31 to S36, which will be described separately.

In step S31, the terminal is powered on to read Amax, Bmax, Cmax, Dmax, Emax, and write Amax into the maximum current limit value of the horn PA.

During the application process, the mobile terminal may read the first peak current Amax of the speaker PA stored in the memory of the mobile terminal, and the second peak currents (Bmax, Cmax, Dmax, Emax) corresponding to the plurality of first power consuming components, respectively. It should be noted that, since the process of obtaining the first peak current Amax of the horn PA and the second peak currents (Bmax, Cmax, Dmax, Emax) corresponding to the plurality of first power consumption components has been described in detail in the foregoing, details are not repeated in this embodiment.

In step S32, the terminal reads the state of the GSM rf PA, and if the GSM rf PA is turned off, the horn PA current limit value a is Amax + Bmax, and if the GSM rf PA is turned on, a is Amax.

In one embodiment, if the mobile terminal detects that only the first power consuming component GSM rf PA is currently in the off state and the other first power consuming components are currently in the on state, the first current limiting value a matching the current power consuming state is Amax + Bmax. If the mobile terminal detects that all current states of the first power consuming components (including the GSM rf PA) are turned on, at this time, the first current limiting value a matching the current power consuming state is Amax. Further, the current limit value a of the horn PA may be adjusted according to the first current limit value a matched with the current power consumption state.

In step S33, the terminal reads the on state of the screen, and if off, the horn PA current limit value a is Amax + Cmax, and if on, a is Amax.

In another embodiment, if the mobile terminal detects that the current state of only the first power consuming component is off and the other first power consuming components are on, the first current limiting value a matching the current power consuming state is Amax + Cmax. If the mobile terminal detects that the current states of all the first power consumption components (including the screen) are all open, at this time, the first current limiting value a matching the current power consumption state is Amax. Further, the current limit value a of the horn PA may be adjusted according to the first current limit value a matched with the current power consumption state.

In step S34, the terminal reads the status of the flash/flashlight, and if turned off, the horn PA current limit value a is Amax + Dmax, and if turned on, a is Amax.

In another embodiment, if the mobile terminal detects that only the first power consuming component flash/flashlight is currently off and the other first power consuming components are currently on, the first current limit value a matching the current power consuming state is Amax + Dmax. If the mobile terminal detects that all current first power consumption components (including a flash lamp/flashlight) are in an on state, at this time, the first current limiting value a matching the current power consumption state is Amax. Further, the current limit value a of the horn PA may be adjusted according to the first current limit value a matched with the current power consumption state.

In step S35, the terminal reads the state of the reverse charging component, and if turned off, the horn PA current limit value a is Amax + Emax, and if turned on, a is Amax.

In another embodiment, if the mobile terminal detects that only the first power consuming component is currently turned off and the other first power consuming components are currently turned on, the first current limiting value a, which matches the current power consuming state, is Amax + Emax. If the mobile terminal detects that the current states of all the first power consumption components (including the reverse charging component) are all open, at this time, the first current limiting value a matching the current power consumption state is Amax. Further, the current limit value a of the horn PA may be adjusted according to the first current limit value a matched with the current power consumption state.
