Description

Method and device for improving endurance time of communication device

Technical Field

The embodiment of the application relates to the field of communication, in particular to a method and a device for improving the endurance time of a communication device.

Background

True Wireless Stereo (TWS) headsets have a great market potential, attracting the competition of numerous manufacturers. The method provides high-quality tone quality, strong endurance and good comfort for users, and the three key indexes become important references for the users to select the TWS earphone. Especially, the cruising problem is always the technical bottleneck of the design of the TWS earphone.

Wherein endurance depends on power consumption, and the larger the power consumption, the less endurance for the TWS headset of the same battery capacity. While increasing battery capacity can effectively increase endurance, it will also result in an increase in the size and weight of the headset. The increase in size and weight of the headset will affect the comfort of the user in wearing the headset for a long time.

Disclosure of Invention

The embodiment of the application provides a method and a device for improving the endurance time of a communication device, which are used for improving the endurance capacity of the communication device.

In a first aspect, an embodiment of the present application provides a method for improving a endurance time of a communication device, where the method includes: the method comprises the steps of obtaining a first state and a second state, wherein the first state indicates whether uplink data comprise valid data, the second state indicates whether downlink data comprise valid data, and further the operating frequency of a processor can be configured according to the first state and the second state.

The method can be applied to a scene that at least two users carry out communication, wherein the uplink data refers to data sent to a communication opposite terminal. The downlink data refers to data received from the opposite end of the call. The valid data refers to data transmitted with an information amount, or the valid data refers to data including substantial content. For example, the valid data may include voice data of a call between users, and for example, the valid data may also include some environmental data, for example, during the call with the user b, the user a plays a piece of audio through another device (e.g., a tablet, a computer, or a television), where the piece of audio is information that the user a wants the user b to hear, and thus the piece of audio is also valid data. Or, when the user a rings or knocks the door bell at home or the user c talks to the user a during the conversation with the user b, the door bell, the knocks, and the voice of the user c are also valid data. It should be understood that the foregoing examples are not intended to limit the embodiments of the present application, and the valid data is not limited to voice data of a call between users, and may also include other data with information content. Then, the example of the user a in the call with the user b additionally explains the concept of downlink data, and the opposite end of the call of the user a is the user b. Thus, the uplink data of the telephony device of the user a refers to data to be sent to the user b, such as the voice data of the user a or the environmental sound of the user a, and the downlink data of the telephony device of the user a refers to the received data from the user b, such as the voice data of the user b or the environmental sound of the user b.

The operating frequency of a processor refers to the clock frequency or master frequency of the processor. Compared with the prior art, in the call process, the operating frequency of the processor is always at the fixed frequency, and the operating frequency of the processor can be dynamically adjusted by combining whether the uplink data comprises the effective data and whether the downlink data comprises the effective data. Because the running frequency of the processor is dynamically variable, the processor can work at a lower running frequency, so that the power consumption of the communication device can be saved, and the endurance time of the communication device is prolonged.

In one possible design, configuring the operating frequency of the processor according to the first state and the second state may employ the following method: and when the uplink data and the downlink data both comprise valid data, configuring the operating frequency of the processor as a first frequency. The first frequency is higher frequency, and the design can ensure that the conversation quality between users is not influenced.

In one possible design, configuring the operating frequency of the processor according to a first state and a second state further includes: and when at least one of the uplink data and the downlink data does not comprise the valid data, configuring the operating frequency of the processor as a second frequency, wherein the second frequency is less than the first frequency.

In one possible design, adjusting the operating frequency of the processor based on the first state and the second state may employ the following: when the uplink data and the downlink data both comprise valid data, configuring the operating frequency of the processor as a first frequency; when at least one of the uplink data and the downlink data does not comprise valid data, adjusting the operating frequency of the processor from a first frequency to a second frequency, wherein the second frequency is smaller than the first frequency. By adopting the design, when the uplink data and the downlink data comprise effective data, the operating frequency of the processor is kept high; when at least one of the uplink data and the downlink data does not include effective data, the processor does not need to be kept at a higher operating frequency, the reduction of the operating frequency of the processor does not affect the communication quality between users, the reduction of the operating frequency of the processor can also realize the power consumption saving of the processor, and the duration of the headset is prolonged.

In one possible design, when neither the uplink data nor the downlink data includes valid data, the operating frequency of the processing is configured to be a third frequency. If the operating frequency of the processor is a second frequency before that, adjusting the operating frequency of the processor from the second frequency to a third frequency, the third frequency being less than or equal to the second frequency. When the uplink data and the downlink data do not comprise effective data, the operating frequency of the processor is reduced, the power consumption of the processor can be effectively saved, and the endurance time of the equipment is prolonged.

In one possible design, adjusting the operating frequency of the processor based on the first state and the second state may employ the following: when the uplink data and the downlink data both comprise valid data, configuring the operating frequency of the processor as a first frequency; when the uplink data and the downlink data do not comprise valid data, adjusting the operating frequency of the processor from a first frequency to a third frequency, wherein the third frequency is smaller than the first frequency. By adopting the design, when the uplink data and the downlink data both comprise effective data, the operating frequency of the processor is kept higher, when the uplink data and the downlink data do not comprise the effective data, the processor does not need to be kept at the higher operating frequency, the operating frequency of the processor is reduced, the communication quality between users cannot be influenced, the power consumption of the processor can be saved by reducing the operating frequency of the processor, and the duration of the headset is prolonged.

In summary, in a possible implementation manner of the embodiment of the present application, the operating frequency of the processor may be set to a corresponding one of a first frequency, a second frequency and a third frequency according to whether the uplink data and the downlink data include valid data, where the first frequency is higher than the second frequency and the third frequency is less than or equal to the second frequency. Setting the operating frequency of the processor to be a first frequency when the uplink data and the downlink data both comprise valid data; setting the operating frequency of the processor to be a second frequency when at least one of the uplink data and the downlink data does not comprise valid data; and when the uplink data and the downlink data do not comprise valid data, setting the operating frequency of the processor as a third frequency. When the uplink data and the downlink data meet the judgment condition, the operating frequency of the processor can be adjusted to the corresponding frequency. That is, when the determination condition is satisfied, the operating frequency of the processor may be switched among the first frequency, the second frequency, and the third frequency, from a lower frequency to a higher frequency, or from a lower frequency to a higher frequency.

In one possible design, the uplink data is stored in a first buffer, and the first buffer is used for storing data to be processed by using a first preset audio algorithm. And when the uplink data does not comprise valid data, setting the first buffer to be zero. By adopting the design, when the uplink data comprises effective data, the first preset algorithm processing is executed on the uplink data, and when the uplink data does not comprise the effective data, the first preset algorithm processing is not executed on the uplink data. Therefore, the sound effect optimization of the uplink data including the effective data can be realized to ensure the user experience, and the waste of power consumption caused by the sound effect optimization of the uplink data not including the effective data can be avoided.

The zeroing of the first cache means that all bytes stored in the first cache are zeroed.

In a possible design, the downlink data is stored in a second buffer, and the second buffer is used for storing data to be processed by using a second preset audio algorithm. And when the downlink data does not comprise valid data, setting the second buffer to zero. By adopting the design, when the downlink data comprises effective data, the second preset algorithm processing is executed on the downlink data, and when the downlink data does not comprise the effective data, the second preset algorithm processing is not executed on the downlink data. Therefore, the method and the device can realize the effect optimization of the downlink data including the effective data to ensure the user experience, and can avoid the waste of power consumption caused by the effect optimization of the downlink data not including the effective data.

Wherein, zeroing the second cache means zeroing all bytes stored in the second cache.

In the embodiment of the application, the running frequency of the slave processor is started at the frequency, and the timer is triggered to start timing. When at least one of the uplink data and the downlink data does not comprise valid data, the time length indicated by the timer is combined to judge whether to execute the adjustment of the operating frequency, so that the influence on the system performance caused by frequently switching the operating frequency of the processor can be avoided.

Illustratively, a segment of speech may be divided into one or more data packets, the size of which may be determined by the audio protocol. For example, every 10ms of speech as a packet, a 3s segment of speech may be split into 300 packets. Each packet may comprise one or more 16-bit (bit) data streams, each bit having a value of 0 or 1. Further, each 16-bit data stream may be converted from a 2-ary system to a 10-ary system, a difference between a 10-ary system number corresponding to each 16-bit data stream and a 10-ary system number corresponding to a baseline may be used as an amplitude of the 16-bit data stream, and an amplitude mean value or an amplitude root mean square and the like of one data packet may be calculated.

Detailed Description

First, technical terms related to the embodiments of the present application will be described below.

1. TWS earphone (TWS Bluetooth earphone)

Compared with a wired earphone, the TWS earphone abandons wired troubles, achieves a real wireless structure, is free to move, can have multiple functions, and has better performances in tone quality, noise reduction and conversation quality. In addition, the TWS earphone is also provided with a portable box with charging and storage functions, and the TWS earphone can be automatically charged when placed into the portable box, so that the charging is very convenient.

The TWS earphone comprises a main ear and an auxiliary ear, wherein the main ear can be responsible for collecting uplink data, and the auxiliary ear can be responsible for collecting downlink data. The stereo system is formed by the main ear and the auxiliary ear, and better user experience can be realized by matching with a professional noise reduction technology.

2. Bluetooth communication

Based on the development of the bluetooth chip technology, terminal devices such as mobile phones and the like can transmit downlink data to the earphones based on a bluetooth protocol and receive uplink data collected by the earphones.

Illustratively, a handset establishes a connection with a headset. When the terminal equipment starts voice call, the earphone is informed to enter a call scene. An application core (ACore) in the headset controls a Digital Signal Processing (DSP) core to perform a call service.

3. Uplink path and downlink path

The uplink data refers to data sent to the opposite call end. The downlink data refers to data received from the opposite end of the call.

The following describes, by taking a scenario in which the terminal device a and the terminal device B communicate with each other, a transmission process of uplink data on an uplink channel of the communication device and a transmission process of downlink data on a downlink channel of the communication device, where the communication device establishes a connection (for example, a bluetooth connection) with the terminal device a. As shown in fig. 1(a), the communication device collects uplink data and transmits the uplink data to the terminal device a, and the terminal device a transmits the uplink data to the terminal device B. And the terminal equipment B sends the downlink data to the terminal equipment A, the terminal equipment A sends the downlink data to the communication equipment, and the communication equipment plays the downlink data. The communication device may be a component in the terminal device a, or may be a device independent from the terminal device a. Illustratively, the communication device may be an earphone, the terminal device a and the terminal device B may be a mobile phone of the user a and a mobile phone of the user B, respectively, the user a and the user B perform a voice call, and the user a wears the earphone. The uplink data and the downlink data mentioned herein refer to uplink and downlink data of the terminal device a or the communication device, the uplink data refers to data that is collected by the communication device and is to be sent to the terminal device B, and the downlink data refers to data that is received by the communication device and is received from the terminal device B.

As shown in fig. 1(b), in the headset uplink path, uplink data may be collected by any one or more of a Main microphone (Main Mic), a sub-Mic, and a bone vibration sensor (VPU), and transmitted to the DSP core via a Codec (Codec). The DSP core receives input uplink data through a communication bus protocol, calls sampling frequency converter (SRC) to process in sequence, and processes the uplink data through a 3A Uplink (UL) algorithm, the SRC and an uplink coding and decoding module. Further, the uplink data processed by the DSP core is transmitted to a Bluetooth (BT) core, and the BT core sends the uplink data to the terminal device a through an air interface. Further, the terminal device a processes the uplink data and sends the processed uplink data to the terminal device B.

As shown in fig. 1(B), the downlink data is sent from the terminal device B to the terminal device a, and the terminal device a may transmit the downlink data to the BT core of the headset through the bluetooth transmission module. In a downlink path, downlink data is transmitted from the BT core to the DSP core, and the DSP core sequentially calls a downlink codec module, an SRC, a 3A Downlink (DL) algorithm, the SRC, an audio mixing and gain processing module to sequentially perform processing on the downlink data, and outputs the downlink data processed by the DSP core through a communication bus protocol. Further, the downlink data processed by the DSP core is transmitted to Codec, and played through a Speaker (SPK). In a call scene, three cores are mainly used in the headset to participate in work, and the Acore is an application core and is mainly responsible for function logic control, such as call starting and call ending. Most functions of the Acore are actually in a sleep state during the whole call, and therefore, the power consumption of the Acore is also low (wherein, the Acore is not shown in fig. 1(a) and 1 (b)). The BT core is mainly responsible for transmitting uplink data and downlink data, and is generally in a low power consumption operating mode. The DSP core is responsible for encoding, decoding and processing uplink data and downlink data, for example, the DSP core may process the uplink data and the downlink data through an audio algorithm such as interface scheduling 3A. Therefore, in a call scenario, the power consumption of the headset is mostly derived from the DSP core. The 3A is a generic term of three algorithms, namely, An Echo Cancellation (AEC), an Automatic Gain Control (AGC), and an Active Noise Control (ANC).

Table 1 shows a cruising ability analysis table of 5 TWS headphones. The general call endurance of the following TWS headset is to be improved and does not reach the endurance level expected by the user.

TABLE 1

In addition, in a call scenario, the DSP core in the TWS headset always operates at a fixed frequency, which is typically set uniformly by the headset when the headset leaves the factory, and the frequency does not change with the change of the surrounding environment, as shown in table 2.

TABLE 2

Audio data	Operating frequency of DSP core
		Uplink data	Fixed frequency M ₁
Downstream data	Fixed frequency M ₁
		Both uplink and downlink data exist	Fixed frequency M ₁
No data exists between uplink and downlink	Fixed frequency M ₁

As can be seen from table 2, the uplink and downlink data states can be divided into four types, where only uplink data exists, only downlink data exists, both uplink and downlink data exist, and both uplink and downlink data do not exist. Under the four states, the DSP core always works at a fixed M ₁ Frequency. In an actual call scenario, the users of both parties of the call speak alternately in most cases, that is, the ratio of the speaking time of the users of both parties to the total call time is low. Illustratively, silence data (which may also be referred to as noise data or background noise data) accounts for up to about 60% of the call scenario.

As shown in fig. 2, in the voice communication process, the situation that the uplink and downlink loads are executed simultaneously, that is, the situation that the uplink and downlink data exist simultaneously, occurs only in a very small time period, but the DSP core always operates at a fixed frequency to ensure that the maximum load can be executed normally. Therefore, the DSP core operating at a fixed frequency will consume a lot of power during the whole call life cycle. The upper half of fig. 2 shows the waveforms of the uplink data and the waveforms of the downlink data, and the lower half of fig. 2 shows the operating frequencies of the DSP cores corresponding to the waveforms of the uplink data and the waveforms of the downlink data.

It is to be understood that the illustrated structure of the embodiments of the present application does not constitute a specific limitation to the earphone. In other embodiments of the present application, the headset may include more or fewer components than shown, or some components may be combined, some components may be split, or a different arrangement of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

The software system of the communication device may employ a layered architecture that divides the software into layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. Fig. 4 is a block diagram of a software configuration of a communication apparatus according to an embodiment of the present application. In some embodiments, the software system of the communication device is divided into three layers, namely, a kernel and driver layer, a framework and algorithm layer and an application layer from bottom to top.

Wherein the application layer may comprise a series of application packages. The framework and algorithm layer provides an Application Programming Interface (API) and a programming framework for the application programs of the application layer. The framework and algorithm layer includes some predefined functions, and illustratively, the framework and algorithm layer includes software modules for implementing the method for improving the endurance time of the communication device according to the embodiments of the present application. The kernel and driver layers are layers between hardware and software.

The embodiment of the application can be applied to a scene of communication between at least two users. For example, the user a makes a voice call with the user B by dialing a mobile phone number of the user B, or the user a makes a voice call or a video call with the user B through preset software. For example, a teleconference is performed between a plurality of users through preset software, or a video call is performed between a plurality of users through preset software. The preset software refers to software with a voice call function or a video call function. Any user can wear the earphone, and the earphone can adopt the method for adjusting the operating frequency of the processor provided by the embodiment of the application. The embodiment of the present application does not limit the specific structure of the earphone and the processor.

The uplink data referred to in the embodiments of the present application may also be referred to as uplink audio data, which refers to audio data sent to the opposite end of the call. The downlink data, which may also be referred to as downlink audio data, refers to audio data received from the opposite end of the call.

Based on this, the embodiment of the present application provides a method for improving a cruising time of a communication device, so as to achieve improvement of a cruising ability of an earphone. The communication device may be a headset, or a chip in the headset, or a processor, or a DSP core, etc. In the following, a communication device is taken as an example, and as shown in fig. 5, the method includes:

s501: the headset acquires a first state and a second state.

The first state indicates whether the uplink data includes valid data, and the first state may be denoted as S _in . Wherein S is _in 1, indicates that the uplink data includes valid data, S _in 0 indicates that the uplink data does not include valid data. The second state indicates whether the downlink data includes valid data, and the second state may be denoted as S _out . Wherein S is _out 1 denotes that the downlink data includes valid data, S _out 0 denotes the followingThe line data does not include valid data.

It should be noted that the uplink data may refer to an uplink data packet, and the downlink data may refer to a downlink data packet. Illustratively, a segment of speech may be divided into one or more data packets, the size of which may be determined by the audio protocol. For example, every 10ms of speech as a packet, a 3s segment of speech may be split into 300 packets. Each packet may comprise one or more 16-bit (bit) data streams, each bit having a value of 0 or 1. In addition, each 16-bit data stream can be converted from a 2-system to a 10-system, and the difference between the 10-system number corresponding to each 16-bit data stream and the 10-system number corresponding to the baseline can be used as the amplitude corresponding to the 16-bit data stream. Further, in the above manner, during the call, the amplitudes of the plurality of uplink packets and the amplitudes of the plurality of downlink packets may be obtained, and further, the waveform of the uplink data and the waveform of the downlink data may be plotted, as shown in fig. 2, and in addition, the baseline shown in fig. 2 is not necessarily 0, and may be other values. Further, the amplitude mean value or the amplitude root mean square of a packet can be calculated.

The valid data referred to in the embodiments of the present application refers to data transmitted with an information amount, or the valid data refers to data including substantial content. For example, the valid data may include voice data of a call between users, or the valid data may refer to non-noise data, or the valid data refers to data other than 0, or the valid data refers to data conforming to a preset curve rule, and the like. For another example, the valid data may also include some environmental data, for example, during the conversation with the user b, the user a plays a piece of audio through another device (e.g., a tablet, a computer, or a television), where the piece of audio is information that the user a wants the user b to hear, and thus the piece of audio is also valid data. Or, when the user a rings or knocks the door bell at home or the user c talks to the user a during the conversation with the user b, the door bell, the knocks, and the voice of the user c are also valid data. It should be understood that the foregoing examples are not intended to limit the embodiments of the present application, and the valid data is not limited to voice data of a call between users, and may also include other data with information content.

For example, but not limited to, the headset may determine whether the uplink data and the downlink data include valid data in the following manners 1 to 3, and then determine the first state and the second state.

Mode 1: whether the data packet includes valid data is determined by detecting whether the data packet is all 0 s. The data packet may be referred to as an uplink data packet or a downlink data packet.

For example, the headset may detect for each packet and determine whether all packets are 0. As shown in fig. 6(a), for each uplink packet, it is determined whether all the uplink packets are 0, and when all the uplink packets are 0, the first state S is obtained _in 0. When the uplink data packet is not completely 0, acquiring a first state S _in 1. Similarly, as shown in fig. 6(b), for each downlink data packet, it is determined whether all downlink data packets are 0, and when all downlink data packets are 0, the first state S is obtained _out 0. When the downlink data packet is not all 0, acquiring a first state S _out ＝1。

And 2, judging whether the data packet comprises valid data or not by detecting whether the energy of the data packet meets a preset condition or not. The data packet may be referred to as an uplink data packet or a downlink data packet.

Illustratively, the energy of the upstream data packet may be characterized by a first parameter, wherein the first parameter is calculated from the amplitude of the upstream data packet. For example, the first parameter may be an amplitude mean or an amplitude root of the uplink data packet. As shown in fig. 7(a), when the earphone determines that the first parameter is less than or equal to the first preset threshold, the first state S is obtained _in 0. Or, when the earphone determines that the first parameter is greater than the first preset threshold, acquiring a first state S _in ＝1。

It should be noted that the setting of the first preset threshold will affect the judgment of the valid data, generally, the first preset threshold may be determined according to an empirical value, and the empirical value is generally determined through experiments or historical data, for example, the value range of the first preset threshold is 30 to 80, and in addition, the first preset threshold may also be adjusted according to the environmental background sound.

Similarly, the energy of the downlink data packet can be characterized by a second parameter, wherein the second parameter is calculated according to the amplitude of the downlink data packet. For example, the second parameter may be an amplitude mean or an amplitude root of the downlink packet. As shown in fig. 7(b), when the earphone determines that the second parameter is greater than the second preset threshold, the second state S is obtained _out 1. Or when the earphone determines that the second parameter is smaller than or equal to a second preset threshold value, acquiring a second state S _out ＝0。

It should be noted that the setting of the second preset threshold will affect the judgment of the valid data, generally, the second preset threshold may be determined according to an empirical value, and the empirical value is generally determined through experiments or historical data, for example, the value range of the second preset threshold is 30-80, and in addition, the second preset threshold may also be adjusted according to the environmental background sound.

It will be appreciated that the first and second preset thresholds may be the same or different.

Mode 3: firstly, logarithm operation is executed for each data in the data packet, and then the logarithm results of the data are summed to be the corresponding energy of the data packet. Further, for the data packets with energy greater than the preset threshold, whether the amplitude distribution curve of each data packet conforms to gaussian distribution is further judged, if so, the data packet is determined to include valid data, and otherwise, the data packet does not include valid data. If the energy is judged to be less than or equal to the preset threshold, it is determined that the data packet does not include valid data, as shown in fig. 8.

The data packet may be an uplink data packet or a downlink data packet. Mode 3 is an open source scheme, and mode 3 may have a plurality of implementation manners, which is not limited in this application embodiment.

In the above-mentioned modes 1 to 3, it should be noted that the first mode 1 to 3 are only examples and are not intended to limit the embodiments of the present application, and those skilled in the art may determine the first state and the second state in other manners.

Secondly, the above-mentioned modes 1 to 3 may also be used in combination, for example, the mode 2 is combined with the mode 3, in the mode 2, when the earphone determines that the first parameter is less than or equal to the first preset threshold, the method of the mode 3 is adopted to determine whether the sum of the logarithm results of each data in the uplink data packet is greater than a preset threshold, and if so, then determine whether the amplitude distribution curve of the uplink data packet conforms to gaussian distribution. For example, the mode 1 is combined with the mode 2, or the mode 1 is combined with the mode 3.

Thirdly, the process of determining whether the uplink data includes valid data and the process of determining whether the downlink data includes valid data are independent of each other, that is, the first state and the second state are also independent of each other.

In addition, in some embodiments, the first buffer stores uplink data, and the first buffer is used to store data that needs to be processed by using a first preset audio algorithm. When the uplink data does not include valid data, the first buffer is set to zero, that is, the uplink data is not processed by adopting a first preset algorithm. Specifically, when the uplink data does not include valid data, the uplink data is transmitted to the bluetooth BT core, and the uplink data is not processed by using the first preset audio algorithm. And when the uplink data comprises effective data, after the uplink data is processed by adopting a first preset audio algorithm, the processed uplink data is transmitted to the BT core. The first preset audio algorithm herein may refer to a 3A algorithm. It should be noted that, when the uplink data does not include valid data, the uplink data at this time is not discarded, but only skips the processing of the first preset audio algorithm, and directly enters the next operation, or the uplink data skips the processing of the first preset audio algorithm and is replaced with preset noise data. Therefore, the sound effect optimization of the uplink data including the effective data can be realized to ensure the user experience, and the power consumption waste caused by the sound effect optimization of the uplink data not including the effective data can be avoided.

Similarly, the second cache stores the downlink data, and the second cache is used for storing the data to be processed by adopting a second preset audio algorithm. And when the downlink data does not comprise the valid data, the second cache is set to zero, namely the downlink data is not processed by adopting a second preset algorithm. Specifically, when the downlink data does not include valid data, the downlink data is transmitted to the codec, and the downlink data is not processed by using the second preset audio algorithm. And when the downlink data comprises effective data, after the downlink data is processed by adopting a second preset audio algorithm, the processed uplink data is transmitted to the coder-decoder. The second preset audio algorithm may be referred to as a 3A algorithm. It should be noted that, when the downlink data does not include valid data, the downlink data at this time is not discarded, but the processing of the second preset audio algorithm is skipped, and the next operation is directly performed, or the downlink data is skipped through the processing of the second preset audio algorithm and is replaced with preset noise data. Therefore, the method and the device can realize the effect optimization of the downlink data including the effective data to ensure the user experience, and can avoid the power consumption waste caused by the effect optimization of the downlink data not including the effective data.

The above-mentioned preset noise data, which may also be referred to as comfort noise data, may be generated from the ambient background sound or stored in the headphone in advance, for example, the preset noise data herein may be all-0 data.

It should be noted that, because the earphone system is in the debugging process within the preset time period when the call is just started, during this time period, even if it is determined that the uplink data does not include valid data, the uplink data is processed by using the first preset audio algorithm, and after the preset time period, if the uplink data does not include valid data, the uplink data is not processed by using the first preset audio algorithm. The same applies to the downlink data.

The stability of the algorithm can be ensured through the design, and the phenomena of system working abnormity, such as blockage, noise and the like caused by frequent system state switching are avoided. The size of the preset time period is related to the performance of the earphone, for example, the value range of the preset time period is 50ms to 200 ms.

Fig. 9 is a schematic diagram illustrating reporting of the first state and the second state, where the first module may be configured to determine the adjusted operating frequency of the DSP core, that is, to execute S502. The second module is for determining a first state and the third module is for determining a second state. In addition, the first module may be named an adaptive frequency modulation module, the second module may be named a first valid data identification module, and the third module may be named a second valid data identification module. The second module may report the first state to the first module after determining the first state. The third module may report the second state to the first module after determining the second state.

Illustratively, the first module, the second module, and the third module may be located at the framework and algorithm layer in fig. 4.

In some embodiments, the DSP core may invoke corresponding computer programs for the first module, the second module, and the third module, respectively, to perform corresponding functions. When the operating frequency of the DSP core is a first frequency, the first module triggers the operating power of the DSP core to be adjusted to a second frequency after determining the adjusted operating frequency (for example, a second frequency) of the DSP core. When the operating frequency of the DSP core is the second frequency, the first module triggers the operating power of the DSP core to be adjusted to the first frequency after determining the adjusted operating frequency (such as the first frequency) of the DSP core.

In some embodiments, the DSP core may invoke corresponding computer programs for the first module, the second module, and the third module, respectively, to perform corresponding functions. When the operating frequency of the DSP core is the first frequency, after the first module determines the adjusted operating frequency (for example, the second frequency) of the DSP core, the first module may notify the application processor of the second frequency, and issue, by the application processor, a first instruction to the DSP core, where the first instruction is used to instruct the DSP core to adjust the operating power of the DSP core to the second frequency. Alternatively, after determining the adjusted operating frequency (e.g., the second frequency) of the DSP core, the first module sends a first notification message to the application processor, where the first notification message indicates to turn down the operating frequency of the DSP core. And the application processor issues a second instruction to the DSP core, wherein the second instruction is used for instructing the DSP core to reduce the running power of the DSP core. When the operating frequency of the DSP core is the second frequency, after the first module determines the adjusted operating frequency (for example, the first frequency) of the DSP core, the first module may notify the application processor of the first frequency, and issue, by the application processor, a third instruction to the DSP core, where the third instruction is used to instruct the DSP core to adjust the operating power of the DSP core to the first frequency. Alternatively, after determining the adjusted operating frequency (e.g., the first frequency) of the DSP core, the first module sends a second notification message to the application processor, where the second notification message indicates to increase the operating frequency of the DSP core. And the application processor issues a fourth instruction to the DSP core, wherein the fourth instruction is used for instructing the DSP core to increase the running power of the DSP core.

In some embodiments, the DSP core may execute computer programs corresponding to the second module and the third module, respectively, and the application processor core executes computer programs corresponding to the first module. When the operating frequency of the DSP core is the first frequency, after determining the adjusted operating frequency (for example, the second frequency) of the DSP core, the first module issues a first instruction to the DSP core, where the first instruction is used to instruct the DSP core to adjust the operating power of the DSP core to the second frequency. Or, after determining the adjusted operating frequency (for example, the second frequency) of the DSP core, the first module issues a second instruction to the DSP core, where the second instruction is used to instruct the DSP core to reduce the operating power of the DSP core. When the operating frequency of the DSP core is the second frequency, after the first module determines the adjusted operating frequency (for example, the first frequency) of the DSP core, the application processor issues a third instruction to the DSP core, where the third instruction is used to instruct the DSP core to adjust the operating power of the DSP core to the first frequency. Or, after determining the adjusted operating frequency (e.g., the first frequency) of the DSP core, the first module issues a fourth instruction to the DSP core, where the fourth instruction is used to instruct the DSP core to increase the operating power of the DSP core.

Fig. 10(a) and 10(b) are schematic diagrams of an upstream path and a downstream path. Illustratively, the user a makes a voice call with the user B, the user a wears an earphone, that is, the mobile phone of the user a and the mobile phone of the user B execute a voice call service, and the earphone establishes a bluetooth connection with the mobile phone of the user a. The uplink data is data collected from the user a side, and the downlink data is data collected from the user B side. Illustratively, the handset of user a may correspond to terminal device a in fig. 1(a), the handset of user B may correspond to terminal device B in fig. 1(a), and the headset may correspond to the communication device in fig. 1 (a).

Specifically, the uplink data can be collected by the Main Mic, the sub Mic and the VPU of the earphone and transmitted to the DSP core through the Codec. The DSP core receives input uplink data through a communication bus protocol, and the DSP core sequentially calls the SRC and the second module to sequentially process the uplink data.

If the second module outputs S _in If the uplink data include valid data, the DSP core sequentially calls the uplink 3A algorithm, the SRC, and the uplink codec module to process the uplink data. Further, the uplink data processed by the DSP core is transmitted to the BT core, and the BT core sends the uplink data to the mobile phone of the user a through the air interface. Further, the mobile phone of the user a processes the uplink data and sends the uplink data to the mobile phone of the user B.

If the second module outputs S _in When the uplink data does not include valid data, in fig. 10(a), the DSP core sequentially calls the fourth module, the SRC, and the uplink codec module to process the preset noise data. And the fourth module replaces the uplink data with the preset noise data. Illustratively, the preset noise data may be generated from the ambient background sound or may be stored in the headset in advance, for example, the preset noise data herein may be all-0 data. Further, the preset noise data processed by the DSP core is transmitted to the BT core, and the BT core sends the preset noise data to the mobile phone of the user a through the air interface. Further, the mobile phone of the user a processes the preset noise data and sends the processed preset noise data to the mobile phone of the user B. In fig. 10(b), the DSP core sequentially calls the SRC and the uplink codec module to process uplink data. Further, the uplink data processed by the DSP core is transmitted to the BT core, and the BT core sends the uplink data to the mobile phone of the user a through the air interface. Further, the mobile phone of the user a processes the uplink data and sends the uplink data to the mobile phone of the user B.

And the mobile phone of the user A receives downlink data from the mobile phone of the user B and transmits the downlink data to the BT core of the earphone through the Bluetooth transmission module of the mobile phone of the user A. Further, downlink data are transmitted from the BT core to the DSP core, and the DSP core sequentially calls the downlink coding and decoding module, the SRC, and the third module to process the downlink data.

If the third module outputs S _out If the downlink data includes valid data, the DSP core sequentially calls a downlink 3A algorithm, an SRC, a mixing and gain processing module to process the downlink data, and outputs the downlink data processed by the DSP core through a communication bus protocol. Further, the downlink data processed by the DSP core is transmitted to Codec and played by SPK.

If the third module outputs S _out In fig. 10(a), the DSP core sequentially calls the fifth module, the SRC, and the mixing and gain processing module to process the preset noise data, and outputs the preset noise data processed by the DSP core through the communication bus protocol. Further, the preset noise data processed by the DSP core is transmitted to Codec and played by SPK. And the fifth module replaces the preset noise data with the downlink data. Illustratively, the preset noise data may be generated from the ambient background sound or stored in the headphone in advance, for example, the preset noise data herein may be all-0 data. In fig. 10(b), the DSP core sequentially calls the SRC, the mixing and gain processing module to process the uplink data, and outputs the uplink data processed by the DSP core through the communication bus protocol. Further, the uplink data processed by the DSP core is transmitted to Codec and played by SPK.

S502: the earphone adjusts the operating frequency of the processor according to the first state and the second state.

In some embodiments, the upstream data and the downstream data each include valid data, and the operating frequency of the headset configuration processor is a first frequency. The first frequency is a higher frequency, and the design can ensure that the call quality between users is not influenced.

In some embodiments, the operating frequency of the headset configuration processor is the second frequency when at least one of the upstream data and the downstream data does not include valid data. The headset may adjust the operating frequency of the processor from a first frequency to a second frequency, the second frequency being less than the first frequency. By adopting the design, when at least one of the uplink data and the downlink data does not comprise effective data, the processor does not need to be kept at a higher operating frequency, the operating frequency of the processor is reduced, the communication quality between users cannot be influenced, the power consumption of the processor can be saved by reducing the operating frequency of the processor, and the duration of the headset is prolonged.

In some embodiments, when neither the uplink data nor the downlink data includes valid data, the operating frequency of the headset configuration processor is a third frequency, and the third frequency is less than or equal to the second frequency. By adopting the design, when the uplink data and the downlink data do not comprise effective data, the processor does not need to be kept at a higher operating frequency, the operating frequency of the processor is reduced, the communication quality between users cannot be influenced, the operating frequency of the processor is reduced, the power consumption of the processor can be saved, and the duration of the headset is prolonged.

Optionally, the operating frequency of the processor may be periodically adjusted according to the first state and the second state, for example, the operating frequency of the processor may be periodically adjusted in response to a determination result whether the uplink data and the downlink data include valid data; the operating frequency of the processor may also be adjusted in response to the determination result of whether the uplink data and the downlink data include valid data.

A specific process for determining the operating frequency of the processor according to the first state and the second state is described below with reference to example 1 and example 2, and it is understood that example 1 and example 2 are only examples and are not intended to limit the embodiments of the present application.

Example 1:

and when the uplink data comprises valid data and the downlink data comprises valid data, adjusting the operating frequency of the processor to be a first frequency. And when the uplink data does not comprise the valid data and/or the downlink data does not comprise the valid data, adjusting the operating frequency of the processor from the first frequency to a second frequency, wherein the second frequency is less than the first frequency. By adopting the method, when the uplink data comprises the effective data and the downlink data comprises the effective data, the operating frequency of the processor is higher. When the upstream data does not include valid data and/or the downstream data does not include valid data, the operating frequency of the processor is low. The running frequency of the processor is dynamically adjusted along with whether the uplink data comprise effective data or not and whether the downlink data comprise effective data or not, so that the power consumption of the processor can be effectively saved, and the duration of the headset is prolonged.

Illustratively, as shown in FIG. 11, the processor includes a DSP core, when S _in 1 and S _out Operating power of the DSP core is at M1 when S is equal to 1 _in 0 and/or S _out 0, i.e. S _in 1 and S _out 0, or S _in 0 and S _out 1, or S _in 0 and S _out And the running power of the DSP core is at M2, and M2 < M1.

TABLE 3

A first state and a second state	Operating frequency of DSP core
		S _in ＝0，S _out ＝1	M2
S _in ＝1，S _out ＝0	M2
		S _in ＝1，S _out ＝1	M1
S _in ＝0，S _out ＝0	M2

In addition, in order to avoid frequently switching the operating frequency of the processor, when the uplink data does not include valid data and/or the downlink data does not include valid data, if the duration that the operating frequency of the processor is at the first frequency exceeds the first duration, the operating frequency of the processor is adjusted from the first frequency to the second frequency. Illustratively, the timer is triggered to start counting when the operating frequency of the slave processor is at a first frequency. The first duration may be determined according to an empirical value, and the empirical value is generally determined through experiments or historical data, for example, the first duration ranges from 80ms to 150 ms. After that, if the uplink data includes valid data and the downlink data does not include valid data, the operating frequency of the processor is adjusted from the second frequency to the first frequency, and the adjustment of the operating frequency is immediately performed to ensure the call quality of the user.

Example 2:

and when the uplink data comprises valid data and the downlink data comprises valid data, adjusting the operating frequency of the processor to be a first frequency. And when the uplink data does not comprise the valid data or the downlink data does not comprise the valid data, adjusting the operating frequency of the processor from the first frequency to a second frequency, wherein the second frequency is less than the first frequency. And when the uplink data does not comprise the valid data and the downlink data does not comprise the valid data, adjusting the operating frequency of the processor from the first frequency to a third frequency, wherein the third frequency is less than the first frequency. By adopting the method, when the uplink data comprises the valid data and the downlink data comprises the valid data, the operating frequency of the processor is the highest. When the upstream data does not include valid data or the downstream data does not include valid data, the operating frequency of the processor is higher. When the upstream data does not include valid data and the downstream data does not include valid data, the operating frequency of the processor is lowest. The running frequency of the processor is dynamically adjusted along with whether the uplink data comprise effective data or not and whether the downlink data comprise effective data or not, so that the power consumption of the processor can be effectively saved, and the duration of the headset is prolonged.

Illustratively, as shown in FIGS. 12 and 13, the processor includes a DSP core, when S _in 1 and S _out The operating power of the DSP core is at M1, 1. When S is _in 0 or S _out 0, i.e. S _in 1 and S _out 0, or S _in 0 and S _out The operating power of the DSP core is at M2, M2 < M1, whichever is 1. When S is _in 0 and S _out And the running power of the DSP core is at M3, and M3 < M2. The upper half of fig. 3 shows the waveforms of the uplink data and the waveforms of the downlink data, and the lower half of fig. 3 shows the operating frequencies of the DSP cores corresponding to the waveforms of the uplink data and the waveforms of the downlink data. Compared with fig. 2, the working frequency of the DSP core changes with the change of the uplink and downlink loads, and power consumption can be saved and endurance time can be improved by dynamically adjusting the working frequency of the DSP core.

TABLE 4

A first state and a second state	Operating frequency of DSP core
		S _in ＝0，S _out ＝1	M2
S _in ＝1，S _out ＝0	M2
		S _in ＝1，S _out ＝1	M1
S _in ＝0，S _out ＝0	M3

In addition, in order to avoid frequently switching the operating frequency of the processor, when the uplink data does not include valid data or the downlink data does not include valid data, if the duration that the operating frequency of the processor is in the first frequency exceeds the second duration, the operating frequency of the processor is adjusted from the first frequency to the second frequency. After that, if the uplink data includes valid data and the downlink data does not include valid data, the operating frequency of the processor is adjusted from the second frequency to the first frequency, and the adjustment of the operating frequency is immediately performed to ensure the call quality of the user. Or, after that, if the uplink data does not include valid data and the downlink data does not include valid data, it may be determined that the time length during which the operating frequency of the processor is at the second frequency exceeds the third time length, and if the time length exceeds the third time length, the operating frequency of the processor is adjusted from the second frequency to the third frequency.

Similarly, when the uplink data does not include valid data and the downlink data does not include valid data, if the duration that the operating frequency of the processor is at the first frequency exceeds the fourth duration, the operating frequency of the processor is adjusted from the first frequency to the third frequency. After that, if the uplink data includes valid data and the downlink data does not include valid data, the operating frequency of the processor is adjusted from the third frequency to the first frequency, and the adjustment of the operating frequency is immediately performed to ensure the call quality of the user. After that, if the uplink data does not include valid data or the downlink data does not include valid data, the operating frequency of the processor is adjusted from the third frequency to the second frequency, and the adjustment of the operating frequency is immediately performed to ensure the call quality of the user.

The method for determining the second duration, the third duration, and the fourth duration may refer to the method for determining the first duration, which is not described herein again.

In addition, the earphone adopting the method of the embodiment shown in fig. 5 is tested through two scenarios of ANC function off and ANC function on, and the specific test parameters are shown in table 5. When the ANC function is off, the average current of the primary and secondary ears using the method of the embodiment shown in fig. 5 is reduced by 1.42mA, the endurance of the headset is increased (4.97-4.41) × 0.6 ≈ 30 minutes, and when the ANC function is on, the average current of the primary and secondary ears is reduced by 1.88mA, and the endurance of the headset is increased (4.37-3.80) ≈ 0.6 ≈ 30 minutes.
