Detailed Description

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

Fig. 1 shows a schematic diagram of an electronic device 100 provided by an embodiment of the present disclosure. Referring to fig. 1, an electronic device 100 includes: a processing component 110, a codec component 120, and a first number of audio acquisition components 130;

a processing component 110 connected to the codec component 120;

a codec component 120, comprising: an input pin 121;

each audio capture assembly 130, includes: a data pin 131 connected to the input pin 121;

the processing component 110 is configured to send a first control signal to the codec component 120 when the remaining power of the electronic device 100 in the sleep state is less than the low power threshold; and when the remaining power is greater than or equal to the low power threshold, sending a second control signal to the codec component 120;

the encoding and decoding component 120 is configured to receive, according to the first control signal, a second number of audio acquisition components 130 smaller than the first number through an input pin 121 and send first audio signals through a data pin 131, encode the first audio signals to obtain first wake-up signals for waking up the electronic device 100, and send the first wake-up signals to the processing component 110;

the encoding and decoding component 120 is further configured to receive, according to the second control signal, a third number of audio acquisition components 130 that is greater than the second number through the input pin 121 and send a second audio signal through the data pin 131, encode the second audio signal to obtain a second wake-up signal for waking up the electronic device 100, and send the second wake-up signal to the processing component 110.

The electronic device 100 may include: mobile terminals and fixed terminals. For example, the electronic device 100 may include a cell phone, a tablet computer, a palmtop computer, a laptop computer, a desktop computer, a wearable mobile device, a smart speaker, and so on.

The processing component 110 may include: an Application Processor (AP).

The coding component 120 may include: devices having both encoding and decoding functions, such as coders-decoders (CODECs).

The audio capture component 130 may include: a device with an audio capture function. Such as a microphone.

It is understood that the first number is an integer greater than 1, the second number is a positive integer, the third number is a positive integer, and the third number is less than or equal to the first number.

The electronic device 100 being in the sleep state may include: the electronic apparatus stops outputting the states of the voice signal and the image signal. In practical applications, taking the electronic device 100 as a mobile phone as an example, when the mobile phone stops displaying images and stops playing sound, the mobile phone may be considered to be in a dormant state. At this time, the power consumption of the mobile phone is usually less than the power consumption threshold.

The remaining power may include: the amount of power in the power supply components in the electronic device. For example, when the electronic device is a mobile phone and the power supply component is a battery, the remaining power can be regarded as the battery power of the mobile phone.

The low battery threshold may include: a certain percentage of the total charge (e.g., 20%), or a certain predetermined charge value (e.g., 200 ma-hrs). When the remaining power of the electronic device is less than the low power threshold, the remaining power stored in the battery of the electronic device may be considered less. At this time, the usable time of the electronic device tends to be more concerned.

The first control signal may be used to enable the input pins 121 of the codec component 120 connected to the second number of audio capture components.

The input pin 121, which is in an enabled state, may receive audio signals transmitted through the data pin by the second number of audio collection components connected thereto. Therefore, compared with the case that the coding and decoding component receives the audio signals sent by the first number of audio acquisition components and selects the first audio signals acquired by the second number of audio acquisition components for coding, the embodiment of the disclosure reduces the number of the audio signals that need to be received by the coding and decoding component 120 when the remaining power of the electronic device is less than the low power threshold, reduces the power consumption of the coding and decoding component, and is beneficial to improving the usable time of the electronic device.

The first control signal may also be used to control the opening of a second number of audio capture assemblies. A second number of audio capture assemblies that are turned on for capturing audio signals.

Like this, compare in all the time and gather speech signal in the audio frequency collection subassembly that uses first quantity, this disclosed embodiment can control when the residual capacity of electronic equipment is less than the low-power threshold value and use the audio frequency collection subassembly of second quantity to gather audio signal, reduces the quantity that is used for carrying on the audio frequency collection subassembly that the pronunciation awakened up, has reduced the consumption when electronic equipment carries out the pronunciation awaken up, is favorable to improving electronic equipment's available duration.

The first audio signal can be sent from the data pins of the second number of audio acquisition components to the input pins of the coding and decoding components in the form of differential signals.

It can be understood that, when the audio acquisition component sends the audio signal to the coding and decoding component in the form of differential signal, two data pins of the audio acquisition component are correspondingly connected with two input pins of the coding and decoding component, and two transmission lines for transmitting the audio signal are arranged between the audio acquisition component and the coding and decoding component, as shown in fig. 2. The first data pin of the audio acquisition component is used for transmitting a first difference sub-signal of an audio signal, the second data pin of the audio acquisition component is used for transmitting a second difference sub-signal of the audio signal, and the first difference sub-signal and the second difference sub-signal have the same amplitude and opposite phase. Therefore, the anti-interference capability of the audio signal sent by the audio acquisition component to the coding and decoding component can be improved, and the signal-to-noise ratio is improved.

Since the power consumption for receiving the audio signals sent by the first number of audio collecting components 130 and processing the audio signals collected by the first number of audio collecting components 130 to obtain the wake-up signal for waking up the electronic device 100 is high, when the remaining power of the electronic device 100 is less than the low power threshold, the audio signals sent by the first number of audio collecting components 130 are still processed to obtain the wake-up signal, which may cause the electronic device 100 to shut down due to power exhaustion in a short time.

Therefore, in the embodiment of the present disclosure, when the remaining power of the electronic device 100 is less than the low power threshold, the first audio signals sent by the second number of audio collecting components 130 are received, and the first audio signals are encoded to obtain the first wake-up signal for waking up the electronic device 100, where the first number is less than the second number, and when the remaining power of the electronic device 100 is less than the low power threshold, and under the condition that the voice wake-up function of the electronic device 100 is ensured to work normally, compared with when the remaining power of the electronic device is less than the low power threshold, the audio collecting components 130 in the first number or the third number are still used for waking up, so that the power consumed by wake-up is reduced, and the available duration of the electronic device when the remaining power is less than the low power threshold is prolonged.

The second control signal may be used to enable the input pins 121 of the codec component 120 connected to the third number of audio capture components.

The second control signal may also be used to control the opening of a third number of audio capture assemblies. A third number of audio capture components in an on state for capturing audio signals.

When the remaining capacity of the electronic device is greater than or equal to the low capacity threshold, it may be considered that the remaining capacity stored in the battery of the electronic device is large. At this time, the effect of the voice wake-up function of the electronic device tends to be more noticeable. Therefore, when the remaining power of the electronic device is greater than or equal to the low power threshold, the audio capture array formed by the third number of audio capture components can be used for waking up.

When the environment in which the electronic device is located is noisy, the effect of the voice awakening function of the electronic device is poor due to more noise signals in the environment, and the user experience is reduced.

This disclosed embodiment receives the second audio signal that audio acquisition component 130 of third quantity sent when the residual capacity is greater than or equal to the low power threshold value, and is right the second audio signal encodes and obtains the second wake-up signal that awakens up electronic equipment 100, and will the second wake-up signal sends for processing component 110, compares in when the residual capacity is greater than or equal to the low power threshold value, still uses the audio acquisition component of second quantity to awaken up for the pronunciation, this disclosed embodiment is favorable to improving the noise reduction effect to the audio signal who gathers, strengthens the recognition ability of electronic equipment to the signal that the user sent in the environment is used for awakening up electronic equipment, and then improves the sensitivity of awakening up the function.

In some embodiments, the processing component 110 is further configured to send the second control signal to the codec component 120 when the remaining power is less than the low power threshold and the remaining power is in an increasing trend;

the processing component 110 is specifically configured to send the first control signal to the codec component 120 when the remaining power is less than the low power threshold and the remaining power is in a decreasing trend.

For example, the situation that the remaining capacity is increasing may include: the electronic device 100 is in a charging state. For example, when the electronic apparatus 100 is connected to a power supply apparatus, the power supply apparatus may input power to the electronic apparatus 100 such that the remaining capacity of the electronic apparatus 100 tends to increase. Here, the power supply apparatus may include: an external power supply, or other electronic devices such as a mobile terminal and a fixed terminal capable of outputting electric power.

It is understood that when the remaining capacity is less than the low capacity threshold and the remaining capacity is on an increasing trend, the electronic device receives a power input, e.g., the electronic device may be charging. At this time, the effect of the voice wake-up function of the electronic device is more focused.

The embodiment of the disclosure receives the second audio signals sent by the audio acquisition components of the third quantity when the remaining power is smaller than the low power threshold and the remaining power is in an increasing trend, encodes the second audio signals to obtain second wake-up signals for waking up the electronic device 100, and sends the second wake-up signals to the processing component 110.

The situation that the residual capacity is in a decreasing trend can include: the electronic device 100 is not in a charging state. It is understood that at this time, the electronic device does not obtain power input. Therefore, as the functional devices included in the electronic apparatus consume power, the remaining power of the electronic apparatus tends to decrease.

It is understood that when the remaining capacity of the electronic device is less than the second capacity threshold and the remaining capacity is in a decreasing trend, the electronic device has no power input or the power input to the electronic device is less than the power consumption consumed by the electronic device. At this time, the usable time of the electronic device tends to be more concerned.

The embodiment of the disclosure receives the first audio signal sent by the audio acquisition component 130 of the second quantity when the remaining power of the electronic device 100 is smaller than the low power threshold and the remaining power is in the decreasing trend, and encodes the first audio signal to obtain the first wake-up signal for waking up the electronic device 100, wherein the first quantity is smaller than the second quantity, so that the voice wake-up function of the electronic device 100 can be guaranteed to work normally, and compared with the case that the remaining power of the electronic device is smaller than the low power threshold and the remaining power is in the decreasing trend, the audio acquisition components of the first quantity or the third quantity are still used for waking up. In some embodiments, the spacing between at least two audio acquisition components 130 is greater than or equal to a distance threshold.

For the sound generated by the same sound source in the environment, the positions of the audio acquisition components in the electronic equipment are different, so that the sound quality of the sound source from the same fixed position collected by each audio acquisition component is different for the sound source at the same fixed position. Here, the sound quality may include: intensity, signal-to-noise ratio, etc.

Taking sound quality as the intensity of sound as an example, generally speaking, when sound propagates in the air, the intensity of sound attenuates with the increase of propagation distance, that is, the longer the sound propagation distance is, the smaller the intensity of sound is, so the intensity of sound collected by the audio collection assembly has a positive correlation with the distance between the audio collection assembly and the sound source. That is, when the distance between the microphone and the sound source generating the sound is small, the intensity of the sound signal collected by the microphone is large; when the distance between the microphone and the sound source generating the sound is large, the intensity of the sound signal collected by the microphone is small.

Therefore, the distance between the two audio acquisition assemblies with the distance larger than the distance threshold value can be changed by setting the distance between the two audio acquisition assemblies with the distance larger than the distance threshold value and the same sound source, so that the sound quality acquired by the two audio acquisition assemblies with the distance larger than or equal to the distance threshold value is changed, the noise reduction effect of the electronic equipment is favorably improved, the recognition capability of the electronic equipment on the voice of the electronic equipment, which is sent by a user in the environment and used for awakening the electronic.

Illustratively, the spacing between the two audio capture components may include: linear spacing. For example, when the audio acquisition component is a microphone, the spacing may comprise a linear spacing between the diaphragms of the two microphones.

The distance threshold value can be set according to the requirements of users. For example, the distance threshold may include: a housing width of the electronic device or a housing length of the electronic device.

Illustratively, the electronic device 100 is a cell phone, the audio acquisition component 130 is a microphone, the first number is 3, and the distance threshold is a housing length of the electronic device.

Fig. 3 is a schematic diagram illustrating an electronic device 100 according to an example embodiment. Referring to fig. 3, the electronic device 100 includes: processing component 110 (not shown), codec component 120 (not shown), earpiece 140, display area 150, and 3 microphones; wherein, the first microphone 130a, the sound inlet hole of the earphone 140 and the display area 150 are disposed on the first surface of the handset housing; a second microphone 130b and a third microphone 130c, both disposed on a second surface of the handset housing, said second surface being perpendicular to said first surface; the housing length (L) of the handset is greater than the housing width (W) of the handset.

At this time, the distance between the second microphone 130b and the first microphone 130a is greater than the distance threshold, and the distance between the second microphone 130b and the third microphone 130c is less than the distance threshold.

Specifically, in practical applications, when a user holds the mobile phone to perform voice wake-up, the side of the mobile phone where the microphone is disposed is usually directed toward the user. Referring to fig. 3, when the user faces the second surface of the mobile phone case to himself, the first microphone 130a is spaced apart from the user by a first distance, the second microphone 130b is spaced apart from the user by a second distance, and the third microphone 130c is spaced apart from the user by a third distance.

It can be appreciated that when the user speaks, since the first distance is greater than the second distance and the first distance is greater than the third distance, the signal-to-noise ratio of the audio signal collected by the first microphone 130a is lower than the signal-to-noise ratio of the audio signal collected by the second microphone 130b, and the signal-to-noise ratio of the audio signal collected by the first microphone 130a is lower than the signal-to-noise ratio of the audio signal collected by the third microphone 130 c.

Since the difference between the second distance and the third distance is smaller, the difference between the signal-to-noise ratio of the audio signal collected by the second microphone 130b and the signal-to-noise ratio of the audio signal collected by the third microphone 130c is smaller than the difference between the signal-to-noise ratio of the audio signal collected by the second microphone 130b and the signal-to-noise ratio of the audio signal collected by the first microphone 130 a.

Therefore, compared with the audio signal collected by the third microphone 130c, the audio signal collected by the second microphone 130b is subjected to noise reduction, the present disclosure wakes up the first microphone 130a and the second microphone with the distance greater than the distance threshold, and reduces the noise of the audio signal collected by the second microphone 130b by the audio signal collected by the first microphone 130a, thereby improving the noise reduction effect.

For example, when the mobile phone is a full-screen mobile phone, that is, the first surface of the mobile phone housing is a display area, the first microphone 130a may be disposed on a third surface of the mobile phone housing, which is parallel to the second surface and perpendicular to the first surface. At this time, the distance between the first microphone 130a and the second microphone 130b may be greater than or equal to the distance threshold.

The processing component 110 may be configured to detect a battery level of the mobile phone. Here, the battery level is the remaining battery level of the mobile phone, and the low battery threshold may be 20% of the total battery level.

When the battery power is lower than 20% of the total battery power and the mobile phone is not charged, the processing module 110 sends a first control signal to the codec module 120, and the single-microphone voice wake-up mode is turned on. At this time, the second number is 1.

For example, turning on a single-microphone voice wake-up mode may include: the coding and decoding component 120 starts the second microphone 130b to collect the audio signal according to the first control signal, receives the first audio signal sent by the second microphone 130b, codes the first audio signal to obtain a first wake-up signal for waking up the mobile phone, and sends the first wake-up signal to the processing component 110.

When the battery power is lower than 20% of the total battery power and the mobile phone is charging, the processing module 110 sends a second control signal to the codec module 120, and the multi-microphone voice wake-up mode is turned on. At this time, the third number may be 2 or 3.

For example, when the third number is 2, turning on the multi-microphone voice wake-up mode may include: the coding and decoding component 120 starts the second microphone 130b and the third microphone 130c to collect the audio signals according to the second control signal, receives the second audio signals sent by the second microphone 130b and the third microphone 130c, codes the second audio signals to obtain a second wake-up signal for waking up the mobile phone, and sends the second wake-up signal to the processing component 110.

As another example, when the third number is 2, turning on the multi-microphone voice wake-up mode may include: the coding and decoding component 120 starts the first microphone 130a and the second microphone 130b to collect the audio signals according to the second control signal, receives the second audio signals sent by the first microphone 130a and the second microphone 130b, codes the second audio signals to obtain a second wake-up signal for waking up the mobile phone, and sends the second wake-up signal to the processing component 110.

Because the distance between the first microphone 130a and the second microphone 130b is greater than the distance threshold, and the distance between the second microphone 130b and the third microphone 130c is less than the distance threshold, compared with the case where the second microphone 130b and the third microphone 130c are turned on to collect audio signals, turning on the first microphone 130a and the second microphone 130b to collect audio signals can improve the accuracy of noise reduction, improve the recognition capability of the electronic device for the voice sent by the user in the environment for waking up the electronic device, and improve the voice wake-up effect.

When the battery power is higher than 20% of the total battery power, the processing module 110 sends a second control signal to the codec module 120, and the multi-microphone voice wake-up mode is turned on. At this time, the third number may be 2 or 3.

Because the distance between the first microphone 130a and the second microphone 130b is greater than the distance threshold, and the distance between the second microphone 130b and the third microphone 130c is smaller than the distance threshold, compared with the case where the second microphone 130b and the third microphone 130c are turned on to collect audio signals, turning on the first microphone 130a and the second microphone 130b to collect audio signals can improve the accuracy of noise reduction, improve the recognition capability of the electronic device for the voice sent by the user in the environment for waking up the electronic device, and improve the voice wake-up effect.

As another example, when the third number is 3, turning on the multi-microphone voice wake-up mode may include: the coding and decoding component 120 starts the first microphone 130a, the second microphone 130b, and the third microphone 130c to collect the audio signals according to the second control signal, receives the second audio signals sent by the first microphone 130a, the second microphone 130b, and the third microphone 130c, codes the second audio signals to obtain a second wake-up signal, and sends the second wake-up signal to the processing component 110. According to the embodiment of the invention, voice awakening is carried out by opening the microphone array formed by the plurality of microphones, so that the noise reduction effect is improved, and the awakening sensitivity is favorably improved.

Fig. 4 shows a flowchart of a control method provided by the embodiment of the present disclosure, which is applied to the electronic device 100 provided by the embodiment of the present disclosure. Referring to fig. 4, the method includes the steps of:

s110: when the residual electric quantity of the electronic equipment in the dormant state is smaller than a low electric quantity threshold value, receiving first audio signals sent by a second number of audio acquisition components smaller than the first number;

s120: encoding the first audio signal to obtain a first wake-up signal for waking up the electronic equipment;

the method further comprises the following steps:
