Detailed ways

In order to make those skilled in the art better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

With the popularity of the full-screen design of electronic devices, in order to save the top space of electronic devices, more manufacturers have adopted ultrasonic proximity monitoring solutions to replace traditional infrared proximity detection solutions on electronic devices. The electronic equipment transmits ultrasonic waves through ultrasonic transmitting devices (such as earpieces, speakers, special ultrasonic transmitters, etc.), and part of the ultrasonic waves propagates through the air directly to the ultrasonic receiving device (pickup) (path 1 in Figure 1), and part of the ultrasonic waves propagates through the air. The object forms reflection and then reaches the ultrasonic receiving device (path 2 in Figure 1). The ultrasonic receiving device picks up the superimposed signal of the direct sound and the reflected sound, which is converted into an audio signal through the A/D converter. The operation state of the object relative to the electronic device is obtained by processing the audio data through the algorithm, and then the display screen of the electronic device is guided to be in a bright screen state or an off screen state.

Specifically, when it is monitored that the electronic device is in a talking state, an ultrasonic signal of a fixed frequency can be sent through the built-in ultrasonic transmitting device of the electronic device. It can be understood that a part of the ultrasonic signal sent by the ultrasonic transmitting device is transmitted through the air and directly received by the ultrasonic wave The other part is reflected by the object through the air and then reaches the ultrasonic receiving device. The ultrasonic receiving device picks up the superimposed signal of the direct sound and the reflected sound, and converts it into an audio signal through A/D. The object can include a human being. face, human body, etc. For example, as shown in Figure 2, a fixed frequency ultrasonic signal is sent through the built-in earpiece, speaker or special ultrasonic transmitter of the electronic device. Part of the ultrasonic signal propagates through the air and reaches the pickup directly, and the other part propagates through the air and forms reflection from the object before reaching the The pickup picks up the superimposed signal of the direct sound and the reflected sound, and converts it into an audio signal through A/D.

In addition, after the electronic device acquires the ultrasonic wave, it can use the A/D converter to convert the acquired ultrasonic wave into audio data, and transmit the audio data to the audio digital signal processor (Audio Digital SignalProcessor, ADSP), and use the audio digital signal processor. A signal processor processes the audio data. At the same time, after the sensor obtains the sensing data, it can transmit the sensing data to the Communication Digital Signal Processor (CDSP), and the communication digital signal processor can process the sensing data to obtain the attitude of the electronic device information, and then the communication digital signal processor transmits the attitude information of the electronic device to the audio digital signal processor according to a fixed period. The audio digital signal processor can process the acquired audio data to obtain the motion state of the object relative to the electronic device, and at the same time it can process the attitude information of the electronic device transmitted by the communication digital signal processor, that is, the audio digital signal processor can The screen of the electronic device is controlled on and off according to the obtained motion state and the posture information of the electronic device.

The communication digital signal processor needs to transmit the obtained attitude information of the electronic device to the audio digital signal processor in a fixed period, which will lead to a large amount of data transmission between the two processors, which will cause the electronic device to generate relatively high noise. large power consumption.

Therefore, in order to overcome the above defects, as shown in FIG. 3 , an embodiment of the present application provides an information processing method, which is applied to a communication digital signal processor of an electronic device, the electronic device further includes an audio digital signal processor, an attitude detection device and screen, the method may include steps S301 to S304.

Step S301: Obtain the relative motion state sent by the audio digital signal processor, where the relative motion state is the motion state between the electronic device and the object, wherein the relative motion state is the audio digital signal processor Obtained from the received audio data returned by the object.

In one embodiment, the communication digital signal processor may receive the relative motion state sent by the audio digital signal processor, where the relative motion state is the motion state between the electronic device and the object, that is, the motion state of the electronic device relative to the object, and the relative motion state is the motion state of the electronic device relative to the object. The motion state is acquired by the audio digital signal processor according to the audio data returned by the object.

If the electronic equipment uses the ultrasonic transmitter and the pickup to obtain the audio data, it first performs analog-to-digital conversion on the data, and then transmits the converted audio data to the audio digital signal processor, and the audio digital signal processor receives the audio data. Then, the audio data can be analyzed to obtain the motion state of the object relative to the electronic device, and then the audio digital signal processor can combine the relative motion state and the attitude information of the electronic device to control the on-off of the electronic device screen, which will lead to Electronic devices generate a large amount of power consumption. However, in the embodiment of the present application, after the audio digital signal processor obtains the motion state of the object relative to the electronic device, the motion state can be transmitted to the communication digital signal processor, and the communication digital signal processor can be used to compare the relative motion state of the electronic device and the electronic device. The attitude information of the electronic device is analyzed, and then the control of the screen on and off of the electronic device can be realized. The specific data transmission process is shown in Figure 4.

Step S302: Acquire attitude data collected by the attitude detection device.

The communication digital signal processor can collect the attitude data of the electronic equipment by using the attitude detection device, wherein the attitude detection device refers to a sensor, which is mainly used for real-time detection of the attitude data of the electronic equipment. Obviously, electronic devices will have built-in sensors for collecting attitude data or operating status information of electronic devices, such as acceleration sensors, gyroscope sensors, infrared sensors, gravity sensors, magnetic sensors, orientation sensors, and linear sensors. In addition, light sensing sensors, pressure sensors, temperature sensors, and proximity sensors that assist in collecting other information of electronic devices can also be built-in. Sensing data collected by the above attitude detection device can be called attitude data of the electronic device. In this embodiment, the attitude data may include at least one of data collected by a gravity sensor, data collected by an acceleration sensor, and data collected by a gyroscope.

Step S303: Determine the posture information of the electronic device according to the posture data.

After acquiring the attitude data of the electronic device, the communication digital signal processor can analyze and process the attitude data to obtain the attitude information of the electronic device. In this embodiment, the attitude information of the electronic device may include acceleration information, distance information, or position information, etc., and the information such as the moving distance and moving direction of the electronic device within a certain period of time can be determined by using this information, and then the attitude of the electronic device can be determined.

Step S304: Control the screen to turn on and off according to the attitude information of the electronic device and the relative motion state.

It can be known from FIG. 4 that the attitude data obtained by the electronic device using the attitude detection device and the audio data obtained by using the ultrasonic transmitter and the pickup are directly or indirectly transmitted to the communication digital signal processor. Obviously, in this embodiment, after the attitude data collected by the attitude detection device is acquired by the communication digital signal processor, it does not need to be transmitted to the audio digital signal processor in a certain period, but only needs to be analyzed and processed to obtain the electronic signal. The attitude information of the device is used by it to control the electronic device screen on and off.

It should be noted that the communication digital signal processor can first obtain the attitude information of the electronic device according to the attitude data, and then receive the relative motion state sent by the audio digital signal processor, or can first receive the relative motion state sent by the audio digital signal processor, Then, the attitude information of the electronic device is obtained according to the attitude data, or the two data can also be obtained according to the actual situation. For example, if the attitude detection device first collects attitude data, the communication digital signal processor can first obtain attitude information of the electronic device according to the attitude data, and then receive the relative motion state sent by the audio digital signal processor. In addition, the communication digital signal processor can also acquire the two data of the attitude information and the relative motion state of the electronic device at the same time, and which data is acquired first is not specifically limited here.

In the information processing method proposed by the embodiment of the present application, the communication digital signal processor uses the attitude detection device to obtain the attitude information of the electronic equipment, and combines the attitude information of the electronic equipment with the relative motion state sent by the audio digital signal processor, Further, the control of the screen on and off of the electronic device can be realized. The present application avoids transmitting the attitude information of the electronic device to the audio digital signal processor in a fixed period, which can reduce the transmission of a large amount of data between the two devices to a certain extent. , thereby reducing the power consumption of the electronic device.

Another embodiment of the present application provides an information processing method, please refer to FIG. 5, a communication digital signal processor applied to an electronic device, the electronic device further includes an audio digital signal processor, an attitude detection device and a screen, the information The processing method may include steps S501 to S504.

Step S501: Obtain the relative motion state sent by the audio digital signal processor, where the relative motion state is the motion state between the electronic device and the object, wherein the relative motion state is the audio digital signal processor Obtained from the received audio data returned by the object.

Step S502: Acquire attitude data collected by the attitude detection device.

Step S503: Determine the posture information of the electronic device according to the posture data.

Step S504: Control the screen to turn on and off according to the attitude information of the electronic device and the relative motion state.

After acquiring the attitude information and relative motion state of the electronic device, the communication digital signal processor can control the brightness of the screen of the electronic device in combination with the attitude information and the relative motion state of the electronic device. When the communication digital signal processor determines that the motion state between the electronic device and the object is that the electronic device approaches the object, and the attitude information of the electronic device changes, the screen can be controlled to be in an off-screen state.

In this embodiment, the motion state between the electronic device and the object may be acquired based on the Doppler effect area difference and the Doppler effect area sum, or the property value of the ultrasonic signal during the transmission process may be directly used to acquire the electronic device and the object state of motion between. In a specific embodiment, the change in the amplitude of the ultrasonic signal can be used to determine the motion state between the electronic device and the object. When the amplitude of the ultrasonic signal becomes larger, it can be determined that the electronic device is approaching the object, and when the ultrasonic signal becomes smaller, it can be determined that the electronic device is far away from the object.

In addition, in order to make the screen on and off control more accurate, in this embodiment, when it is determined that the amplitude of the ultrasonic signal becomes larger, it can be further judged whether the amplitude of the ultrasonic signal is greater than the first preset threshold, and if the amplitude of the ultrasonic wave is greater than the The first preset threshold determines that the electronic device approaches the object. At the same time, the communication digital signal processor can determine whether the attitude information of the electronic device changes within the preset time period, and if the attitude information of the electronic device changes within the preset time period, it can control the screen to be in an off-screen state. In this embodiment, the attitude information of the electronic device may include gravity information, acceleration information, and gyroscope information, etc. When judging whether the attitude information of the electronic device has changed, it is possible to compare whether the attitude information of the electronic device has changed at two moments before and after. , if the posture information of at least two electronic devices changes at two moments before and after, it can be determined that the posture information of the electronic devices changes. At this time, the electronic device can be controlled to be in an off-screen state.

In one embodiment, when the relative motion state is that the electronic device is in a state where the relative position of the electronic device remains unchanged relative to the object and the attitude information of the electronic device has not changed, the last motion state of the electronic device is acquired , and control the on/off of the screen according to the last relative motion state. In other words, if it is determined that the motion state of the electronic device relative to the object has not changed and the attitude information of the electronic device has also changed, then the last motion trend of the electronic device is obtained. If it is determined that the last relative motion state of the electronic device is approaching the object, the screen of the control electronic device continues to be in the off-screen state. If it is determined that the last relative motion state of the electronic device is away from the object, the screen of the electronic device is controlled to continue to be in the bright screen state. How to determine whether the relative motion state of the electronic device is approaching the object or moving away from the object has been described in detail above, and will not be described in detail here.

In addition, when the relative motion state is that the electronic device is far away from the object and the attitude information of the electronic device changes, the screen is controlled to be in a bright screen state. Similarly, in order to judge whether the relative motion state is that the electronic device is far away from the object, the amplitude of the ultrasonic wave at different times can be obtained first, and then it can be determined whether the amplitude of the ultrasonic signal gradually becomes smaller. In order to make the determination of the relative motion state more accurate, this embodiment can further determine whether the amplitude of the ultrasonic signal is less than a second preset threshold, and if the amplitude of the ultrasonic wave is less than the second preset threshold, it is determined that the electronic device is far away from the object . At this time, if the attitude information of the electronic device also changes, the communication digital signal processor controls the screen of the electronic device to be in a bright screen state.

It should be noted that when it is determined that the relative motion state is that the electronic device is close to or away from the object, but the attitude information of the electronic device has not changed, at this time, the communication digital signal processor can preferentially control the electronic device according to the motion state of the electronic device relative to the object. The screen turns on and off. Obviously, in this embodiment, the control of the screen on and off of the electronic device is mainly based on the relative motion state, and the change of the posture information of the electronic device is used to assist the change of the motion state.

An information processing method proposed in the implementation of this application controls the screen on and off comprehensively by combining the attitude information of the electronic device and the relative motion state. If the relative motion state is different from the attitude information of the electronic device, the corresponding screen on and off control will not Similarly, the control of the screen on and off can be made more intelligent through this information processing method.

Yet another embodiment of the present application provides an information processing method, which is applied to an audio digital signal processor of an electronic device. The electronic device further includes a communication digital signal processor, an attitude detection device, and a screen. Please refer to FIG. 6 , the information The processing method may include steps S601 to S602.

Step S601: Acquire a relative motion state according to the audio data returned by the object, where the relative motion state is a motion state between the electronic device and the object.

In this embodiment, the electronic device may include an ultrasonic sending device and an ultrasonic receiving device at the same time. In the process of the ultrasonic sending device moving relative to the object, the essence is that the electronic device moves relative to the object, so the ultrasonic receiving device also moves relative to the object. According to the Doppler effect, the wavelength of the radiation of the object changes due to the relative motion of the wave source (electronic device) and the observer (object). The Doppler effect formula is as follows:

Among them, f' is the observed frequency, f is the original emission frequency of the emission source in the medium, v is the propagation speed of the wave in the medium, v ₀ is the moving speed of the observer, if the observer is close to the emission source, the front The operation symbol is +, otherwise it is -; v _s is the moving speed of the emission source. If the object is close to the observer, the front operation symbol is -, otherwise, it is +. According to the Doppler effect formula, when the emission source is relatively close to the observer, the frequency of the signal received by the observer will become larger; when the emission source is relatively far away from the observer, the frequency of the signal received by the observer will become smaller; When the emission source and the observer are relatively stationary, the frequency of the signal received by the observer is consistent with the emission source.

In one embodiment, after the electronic device receives the ultrasonic signal through the ultrasonic receiving device, it can acquire the attribute value of the ultrasonic signal during the transmission process, and calculate the Doppler effect of the ultrasonic signal during the transmission process based on the attribute value Area difference and Doppler effect area sum. The attribute value may include the transmission frequency, transmission amplitude, transmission time, etc. of the ultrasonic signal transmitted by the ultrasonic transmission device, and the frequency variation range, reception amplitude, reception time, etc. of the ultrasonic signal received by the ultrasonic reception device. Do limit.

The electronic device can obtain the motion state between the electronic device and the object based on the Doppler effect area difference and the Doppler effect area sum. From the above introduction, we can know that the motion state between the electronic device and the object may include the trend of the electronic device. It is close to the object, the electronic device is far from the object, and the relative position between the electronic device and the object is unchanged. If the property values of the ultrasonic signals during transmission are different or the difference between the Doppler effect areas and the sum of the Doppler effect areas are not the same, the corresponding motion states may also be different. In this embodiment, when the amplitude of the ultrasonic wave increases, it indicates that the object is approaching the electronic device, and when the amplitude of the ultrasonic wave decreases, it indicates that the object is far away from the electronic device. The relative positions of the objects remain unchanged. In addition, the motion state between the electronic device and the object can also be determined according to other attribute values of the ultrasonic signal during the transmission process, and which method to use to obtain the motion state is not specifically limited here.

Step S602: Send the relative motion state to the communication digital signal processor, instruct the communication digital signal processor to obtain the attitude data collected by the attitude detection device, and determine the attitude of the electronic device according to the attitude data information, and control the screen to turn on and off according to the posture information of the electronic device and the relative motion state.

After the audio digital signal processor obtains the relative motion state, the relative motion state can be sent to the communication digital signal processor, instructing the communication digital signal processor to obtain the attitude data collected by the attitude detection device, and then according to the attitude The data determines the posture information of the electronic device, and controls the screen to turn on and off according to the posture information of the electronic device and the relative motion state. The attitude information of the electronic device may include information such as the moving speed, the moving distance, and the moving direction of the electronic device.

Before sending the relative motion state to the communication digital signal processor, the audio digital signal processor may determine whether the relative motion state acquired this time does not match the relative motion state acquired last time. In one embodiment, after acquiring the relative motion state, the audio digital signal processor can compare the current relative motion state acquired by the audio digital signal processor with the relative motion state acquired last time, and determine the electronic Whether the motion state between the device and the object matches, if the relative motion state acquired this time matches the relative motion state acquired last time, the audio digital signal processor is used to re-acquire the audio data and the motion state corresponding to the audio data. If the relative motion state acquired this time does not match the relative motion state acquired last time, the relative motion state acquired this time is sent to the communication digital signal processor. Obviously, the audio digital signal processor sends the relative motion state to the communication digital signal processor only when it is determined that the relative motion state of the current time has changed from the relative motion state obtained last time, otherwise the relative motion state does not need to be sent.

In this embodiment, it can be judged whether the motion states acquired by the electronic device before and after the two acquisitions match by comparing the Doppler effect area difference and the Doppler effect area sum. Whether the matching degree between the two is greater than the first preset matching degree, if it is greater than the first preset matching degree, it indicates that the motion state between the electronic device and the object matches, otherwise, it indicates the motion state between the electronic device and the object twice before and after. Mismatch. In addition, it can also be judged whether the matching degree between the sum of the Doppler effect areas obtained twice before and after is less than the second preset matching degree, and if it is less than the second preset matching degree, it indicates that the motion state between the electronic device and the object is matched , otherwise it indicates that the motion state between the electronic device and the object does not match. It should be noted that when judging whether the motion state between the electronic device and the object matches the two times before and after, this embodiment can also directly use the attribute value of the ultrasonic signal in the transmission process to judge, and which method is used to judge here. No explicit restrictions are imposed.

In the information processing method proposed in the embodiment of the present application, the audio digital signal processor determines whether to transmit the relative motion state acquired this time to the communication digital signal processor by comparing the relative motion states before and after. The relative motion states obtained by the communication digital signal processor are all valid data, and the transmission of unnecessary data can be reduced to a great extent, and the operating power consumption of the electronic equipment can be reduced.
