[0048] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] It will be apparent to those skilled in the art that various modifications and variations can be made in this application without departing from the spirit or scope of this application. Therefore, this application is intended to cover modifications and variations of this application that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the embodiments provided in the examples of this application can be combined with each other without contradiction.

[0050] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0051] As described in the background technology section, the types of microphones in current electronic devices are relatively simple, and the cost of the electronic devices is relatively high.

[0052] The inventors have found that this is because in order to ensure that the electronic device can be used in various scenarios, multiple omnidirectional microphones are usually set in the electronic device to collect sound signals. However, the cost of omnidirectional microphones is relatively high, resulting in a high cost of the electronic device.

[0053] Moreover, current electronic devices mainly use omnidirectional microphones to collect sound signals when collecting sound in a specific direction, and then use multiple algorithms to process the signals to achieve sound collection in a specific direction. In the process of algorithmic processing of the signal, the more algorithms involved, the more complex it is, and the higher the cost. Correspondingly, the cost of the electronic equipment is higher.

[0054] In addition, when using algorithms to process the sound collected by the microphone, there is a phenomenon of sound leakage. Therefore, the sealing requirements of electronic equipment are currently very high.

[0055] In view of this, an embodiment of the present application provides an information processing method, which is applied to an electronic device. As shown in FIG1 , the electronic device includes a first microphone 10 and a second microphone 20 , wherein the sound pickup range of the first microphone 10 is smaller than the sound pickup range of the second microphone 20 . As shown in FIG2 , in this embodiment, the information processing method includes:

[0056] S1: responding to a first instruction, collecting a signal using the first microphone;

[0057] S2: Respond to the second instruction and use the second microphone to collect signals.

[0058] Optionally, in one embodiment of the present application, the first microphone is a directional microphone and the second microphone is an omnidirectional microphone; wherein the directional microphone, also known as a directional microphone, is a microphone designed to capture sounds from a specific direction; the omnidirectional microphone is an audio capture device with a wide range of sound, suitable for occasions such as multi-person meetings and group discussions. However, this application does not limit this, and the specific situation may vary.

[0059] It should be noted that the information processing method provided in the embodiment of the present application can collect signals using the first microphone by responding to a first instruction when the electronic device is used in a scenario with a small sound pickup range, and can collect signals using the second microphone by responding to a second instruction when the electronic device is used in a scenario with a large sound pickup range.

[0060] It can be seen that the electronic device used in the information processing method provided in the embodiment of the present application includes two microphones with different pickup ranges, namely a first microphone and a second microphone. Therefore, in different application scenarios, different microphones can be used to collect signals by responding to different first instructions or second instructions, thereby avoiding the high cost and high sealing requirements of the electronic device caused by using an algorithm to process the signal collected by the omnidirectional microphone to achieve sound collection in a specific direction, thereby reducing the cost of the electronic device and reducing the sealing requirements when the electronic device is manufactured.

[0061] Moreover, in an embodiment of the present application, the electronic device includes two microphones with different pickup ranges, namely a first microphone and a second microphone, and the cost of the first microphone is less than the cost of the second microphone, thereby further reducing the cost of the electronic device while having the same number of microphones in the electronic device.

[0062] Optionally, in one embodiment of the present application, the signals collected by the first microphone and the second microphone are sound signals, so that the electronic device can use microphones with different pickup ranges when applying different sound collection range scenarios. For example, when the electronic device is applied to a directional sound collection scenario such as a single-person call, the first microphone can be used to collect signals by responding to a first instruction. When the electronic device is applied to an omnidirectional sound collection scenario such as a multi-person meeting, the second microphone can be used to collect sound signals by responding to a second instruction.

[0063] Specifically, based on the above embodiment, in one embodiment of the present application, as shown in FIG3 , the information processing method further includes:

[0064] S3: Acquire the relative position of the target object and the electronic device;

[0065] S4: Generate the first instruction or the second instruction based on the relative position of the target object and the electronic device. Specifically, if the target object is located within the sound signal collection range of the first microphone, generate the first instruction and use the first microphone to collect the sound signal; otherwise, generate the second instruction and use the second microphone to collect the sound signal.

[0066] It should be noted that in the above embodiment, the information processing method obtains the relative position of the target object and the electronic device, and automatically generates a first instruction or a second instruction based on the relative position of the target object and the electronic device, so that when applied to different scenarios, it automatically switches to using the first microphone or using the second microphone. While reducing the cost of the electronic device, it does not require user participation and has a high user experience.

[0067] Based on the above embodiments, in one embodiment of the present application, before using the first microphone or the second microphone to collect sound signals, the method further includes: using the first microphone or the second microphone to perform ultrasonic detection to obtain the relative position of the target object and the electronic device.

[0068] In specific applications, in one embodiment of the present application, the information processing method can first use a first microphone for ultrasonic detection. If the first microphone detects the position of the target object, a first instruction is generated, and in response to the first instruction, the first microphone is used to collect sound signals. Otherwise, a second instruction is generated, and in response to the second instruction, the second microphone is used to collect sound signals.

[0069] In another embodiment of the present application, the information processing method first uses a second microphone to perform ultrasonic detection. If the second microphone detects that the location of the target object is within the signal collection area of ​​the first microphone, a first instruction is generated, and in response to the first instruction, the sound signal is collected using the first microphone. Otherwise, a second instruction is generated and the sound signal is collected using the second microphone.

[0070] In another embodiment of the present application, in order to improve the response speed of the information processing method, the information processing method first uses the second microphone to collect sound signals, and simultaneously uses the first microphone to perform ultrasonic detection. If the first microphone detects that the position of the target object is within its signal collection range, it switches to the first microphone to collect sound signals. If the first microphone does not detect the position of the target object, it means that the target object is not within the signal collection range of the first microphone, and the second microphone is maintained to collect signals until the target object is within the signal collection range of the first microphone.

[0071] It should be noted that, in the above embodiment, the second instruction is also used to instruct the first microphone to perform ultrasonic detection, so that in response to the same instruction, the second microphone is used to collect sound signals and the first microphone is used to perform ultrasonic detection at the same time, thereby simplifying the control flow of the information processing method.

[0072] It should also be noted that when the information processing method uses ultrasonic detection to obtain the relative position of the target object and the electronic device, the electronic device also includes a sound output component (such as a speaker). In this embodiment, taking the use of a second microphone for ultrasonic detection as an example, the information processing method first uses the sound output component to emit an ultrasonic signal. The ultrasonic signal encounters the target object and is reflected by the target object, and then is received by the second microphone. The relative position of the target object and the electronic device is obtained based on the ultrasonic signal emitted by the sound output component and the ultrasonic signal received by the second microphone.

[0073] In other embodiments of the present application, the electronic device further includes an ultrasonic receiving component, and the information processing method utilizes the ultrasonic receiving component to receive ultrasonic waves reflected by the target object. This is not limited in the present application and depends on the specific circumstances.

[0074] It should be noted that, in the above embodiment, if the target object is within the signal collection range of the first microphone, the position of the target object during the use of the electronic device may be fixed or mobile. For example, the target object may walk back and forth in front of the electronic device during a call using the first microphone. Therefore, based on any of the above embodiments, in one embodiment of the present application, the method further includes:

[0075] When using the first microphone to collect the sound signal of the target object, the second microphone is also used to detect the target object, so that when the relative position of the target object and the electronic device changes, the sound pickup direction of the first microphone is controlled to change accordingly, so that the target object is always located within the signal collection range of the first microphone. Further, when the first microphone is used to collect the sound of a fixed object, the sound quality collected by the first microphone is improved, thereby improving the user experience.

[0076] Optionally, based on the above embodiments, in one embodiment of the present application, if the target object is within the signal collection range of the first microphone, the first instruction is also used to instruct the use of the second microphone for ultrasonic detection, so that in response to the same instruction, the first microphone is used to collect sound signals and the second microphone is used to perform ultrasonic detection at the same time, thereby simplifying the control flow of the information processing method.

[0077] It should be noted that, in this embodiment, in addition to using ultrasound to obtain the relative position of the target object and the electronic device, the information processing method can also obtain the relative position of the target object and the electronic device through other methods.

[0078] Specifically, in one embodiment of the present application, the electronic device further includes an image acquisition component. In this embodiment, before using the first microphone or the second microphone to acquire a sound signal, the method further includes: using the image acquisition component to acquire an image to obtain a relative position of the target object and the electronic device. Optionally, the image acquisition component may be a camera.

[0079] In another embodiment of the present application, the electronic device further includes a positioning component. In this embodiment, before using the first microphone or the second microphone to collect the sound signal, the method further includes: using the positioning component to obtain the relative position of the target object and the electronic device. Optionally, the positioning sensor can be a distance sensor, a radar, a time-of-flight (TOF) sensor, or an ultra-wideband signal (UWB) locator, etc. This application does not limit this, and the specific situation depends on the circumstances. Among them, radar is a system that detects the position and speed of a target by emitting electromagnetic waves and receiving their reflected waves; ToF (Time of Flight) sensor is a device that measures distance based on the flight time of light; UWB positioning technology is a high-precision wireless positioning method based on ultra-wideband signals.

[0080] In other embodiments of the present application, the information processing method may also obtain the relative position of the target object and the electronic device through other means, which is not limited in the present application and depends on the specific circumstances.

[0081] Optionally, in one embodiment of the present application, if the electronic device is a flip-top electronic device, the information processing method is applied when the electronic device is in an open state, so as to facilitate acquisition of the relative position of the target object and the electronic device. However, this application does not limit this, and the specific application will depend on the specific situation.

[0082] Based on any of the above embodiments, in one embodiment of the present application, the electronic device further includes a physical control, which can generate a first instruction or a second instruction under different trigger operations, so that the user can actively select the sound collection mode of the electronic device according to their own usage needs, determine the operation of the first microphone and / or the second microphone, or actively intervene when the working microphone automatically selected by the electronic device does not meet their expectations, thereby improving the user experience.

[0083] In another embodiment of the present application, the electronic device also includes a virtual control displayed on the operating interface of the electronic device, and the virtual control can generate a first instruction or a second instruction under different trigger operations, so that the user can actively select the sound collection mode of the electronic device according to his or her usage needs, determine whether the first microphone and / or the second microphone are working, or actively intervene when the working microphone automatically selected by the electronic device does not meet the user's expectations, thereby improving the user experience.

[0084] In another embodiment of the present application, the electronic device may include both physical controls and virtual controls to provide the user with more choices, but the present application does not limit this and it depends on the specific circumstances.

[0085] Based on any of the above embodiments, in one embodiment of the present application, the information processing method further includes:

[0086] When the target object is located within the signal collection range of the first microphone, if the sound signal collected by the first microphone includes other signals in addition to the target signal, the first instruction and the second instruction are generated to use the first microphone to collect the sound signal and perform noise cancellation processing based on the sound signal collected by the second microphone, wherein the target signal is the sound signal of the target object.

[0087] For example, when the target object is making a phone call in a noisy environment, the sound signal collected by the first microphone includes not only the sound signal of the target object but also other sound signals in the surrounding environment. In this embodiment, the information processing method can simultaneously start the first microphone and the second microphone to work, so as to use the first microphone with a smaller sound collection range to collect the sound signal of the area where the target object is located, thereby improving the clarity of the sound collected by the target object, and use the second microphone with a larger sound collection range to collect the sound signal in a larger range including the area where the target object is located, thereby improving the clarity of the sound collected by the environmental noise, and then perform noise cancellation processing based on the sound signal collected by the second microphone to further improve the clarity of the sound of the target object collected by the electronic device.

[0088] It should be noted that the above example is only one application scenario and does not limit the application scenario of the information processing method provided in the embodiment of the present application.

[0089] Specifically, in one embodiment of the present application, performing noise cancellation based on the sound signal collected by the second microphone includes: performing noise cancellation based on the sound signal collected by the first microphone and the sound signal collected by the second microphone.

[0090] Optionally, in one embodiment of the present application, the frequency of the target signal is different from the frequency of the other signals, such as human voice and ambient music. In this embodiment of the present application, the information processing method can perform noise cancellation on the sound signal collected by the first microphone based on the frequency of the target signal and the frequency of the other signals. Specifically, it can be to obtain the frequency of other signals based on the sound signal collected by the second microphone, obtain the sound signal frequency and the frequency of other signals of the target object based on the sound signal collected by the first microphone, and then process the frequency of the sound signal collected by the first microphone according to the frequency of the other signals collected by the second microphone to obtain the sound signal of the target object.

[0091] In another embodiment of the present application, the timbre and / or voiceprint of the target signal is different from the timbre and / or voiceprint of the other signals, such as the voices of different people. In the embodiment of the present application, taking voiceprint as an example, the information processing method performs noise cancellation processing on the sound signal collected by the first microphone based on the voiceprint of the target signal and the voiceprint of the other signals. Specifically, it can be to obtain the voiceprint of other signals based on the sound signal collected by the second microphone, obtain the voiceprint of the target signal and the voiceprint of other signals based on the sound signal collected by the first microphone, and then process the voiceprint of the sound signal collected by the first microphone through the voiceprint of the other signals collected by the second microphone to obtain the sound signal of the target object.

[0092] In another embodiment of the present application, the electronic device includes at least two second microphones; in this embodiment, performing noise cancellation based on the sound signal collected by the second microphone includes: performing noise cancellation based on the sound signal collected by the second microphone includes: performing noise cancellation based on the sound signals collected by at least two second microphones. In this embodiment of the present application, the information processing method performs noise cancellation only based on the sound signals collected by different second microphones. In other embodiments of the present application, the information processing method may also use other noise cancellation methods, which are not limited by this application and will be determined based on specific circumstances.

[0093] It should be noted that, in the above embodiment, when the first microphone is used to collect sound signals and noise cancellation is performed based on the sound signals collected by the second microphone, the target object is located within the signal collection range of the first microphone. In this embodiment, the first instruction is not used to instruct the second microphone to perform ultrasonic detection. Specifically, in this embodiment, the information processing method includes:

[0094] If the target object is within the signal collection range of the first microphone (for example, the user is in front of a computer), and the scene where the target object is located has no other signals except the sound signal of the target object, a first instruction is generated to use the first microphone to collect the sound signal and use the second microphone to perform ultrasonic detection. At this time, noise cancellation processing is not activated to reduce power consumption;

[0095] If the target object is within the signal collection range of the first microphone, and the scene where the target object is located contains other signals in addition to the sound signal of the target object, generating a first instruction and a second instruction to collect the sound signal using the first microphone and to collect the sound signal using the second microphone, thereby performing noise cancellation processing based on the sound signal collected by the second microphone;

[0096] If the target object is not within the signal collection range of the first microphone (for example, when the user is not in front of the computer), a second instruction is generated to use the second microphone to collect sound signals and use the first microphone for ultrasonic detection. It should be noted that in this embodiment, the user can enable noise cancellation processing according to their needs. For example, if the sound signal collected by the second microphone contains a lot of interference signals, noise cancellation processing is enabled; if the sound signal collected by the second microphone contains little or no interference signals, noise cancellation processing is not enabled. This application does not limit this, and the specific situation depends on the situation.

[0097] It should be noted that the above embodiments all describe the information processing method by taking the scenario in which the information processing method is used for conversation as an example. In other embodiments of the present application, the information processing method can also be used in the scenario of data transmission. The scenario in which the information processing method is used for data transmission is described below.

[0098] Specifically, in one embodiment of the present application, the signal collected by the first microphone or the second microphone is an ultrasonic signal, and the signal collected by the first microphone or the signal collected by the second microphone is used to determine the relative position of the target object and the electronic device; in this embodiment, the method also includes: if the relative position of the target object and the electronic device meets the first condition, establishing a data transmission path between the target object and the electronic device for data transmission, so as to realize interconnected screen projection, etc.

[0115] In response to a first instruction, collecting a signal using the first microphone;

[0116] In response to the second instruction, the second microphone is used to collect signals.

[0117] Optionally, in one embodiment of the present application, the first microphone is a directional microphone and the second microphone is an omnidirectional microphone; wherein the directional microphone, also known as a directional microphone, is a microphone designed to capture sounds from a specific direction; the omnidirectional microphone is an audio capture device with a wide range of sound, suitable for occasions such as multi-person meetings and group discussions. However, this application does not limit this, and the specific situation may vary.

[0118] Optionally, in one embodiment of the present application, the signals collected by the first microphone and the second microphone are sound signals, so that the electronic device can use microphones with different pickup ranges when applying different sound collection range scenarios. For example, when the electronic device is applied to a directional sound collection scenario such as a single-person call, the first microphone can be used to collect signals by responding to a first instruction. When the electronic device is applied to an omnidirectional sound collection scenario such as a multi-person meeting, the second microphone can be used to collect sound signals by responding to a second instruction.

[0119] Based on any of the above embodiments, in one embodiment of the present application, the processing component is further configured to execute:

[0120] Obtaining a relative position of a target object and the electronic device;

[0121] Based on the relative position of the target object and the electronic device, the first instruction or the second instruction is generated. Specifically, if the target object is located within the sound signal collection range of the first microphone, the first instruction is generated and the sound signal is collected using the first microphone; otherwise, the second instruction is generated and the sound signal is collected using the second microphone.

[0122] Based on the above embodiments, in one embodiment of the present application, before executing the collection of sound signals using the first microphone or the second microphone, the processing component is also used to execute: performing ultrasonic detection using the first microphone or the second microphone to obtain the relative position of the target object and the electronic device.

[0123] It should be noted that when the electronic device uses ultrasonic detection to obtain the relative position of the target object and the electronic device, the electronic device also includes a sound output component (such as a speaker). In this embodiment, taking the use of a second microphone for ultrasonic detection as an example, the electronic device first uses the sound output component to emit an ultrasonic signal. The ultrasonic signal encounters the target object and is reflected by the target object, and then is received by the second microphone. Based on the ultrasonic signal emitted by the sound output component and the ultrasonic signal received by the second microphone, the relative position of the target object and the electronic device is obtained. In other embodiments of the present application, the electronic device also includes an ultrasonic receiving component. The electronic device uses the ultrasonic receiving component to receive ultrasonic waves reflected by the target object. This is not limited in this application and depends on the specific circumstances.

[0124] In another embodiment of the present application, the electronic device further includes an image acquisition component. In this embodiment, before using the first microphone or the second microphone to acquire a sound signal, the processing component is further configured to: use the image acquisition component to acquire an image to obtain a relative position of the target object and the electronic device. Optionally, the image acquisition component may be a camera.

[0125] In another embodiment of the present application, the electronic device further includes a positioning component. In this embodiment, before using the first microphone or the second microphone to collect the sound signal, the processing component is further used to: use the positioning component to obtain the relative position of the target object and the electronic device. Optionally, the positioning sensor can be a distance sensor, a radar, a time-of-flight (TOF) sensor, or an ultra-wideband signal (UWB) locator, etc. This application does not limit this, and the specific situation depends on the circumstances. Among them, radar is a system that detects the position and speed of a target by emitting electromagnetic waves and receiving their reflected waves; ToF (Time of Flight) sensor is a device that measures distance based on the flight time of light; UWB positioning technology is a high-precision wireless positioning method based on ultra-wideband signals.

[0127] In another embodiment of the present application, the electronic device also includes a virtual control displayed on the operating interface of the electronic device, and the virtual control can generate a first instruction or a second instruction under different trigger operations, so that the user can actively select the sound collection mode of the electronic device according to his or her usage needs, determine whether the first microphone and / or the second microphone are working, or actively intervene when the working microphone automatically selected by the electronic device does not meet the user's expectations, thereby improving the user experience.

[0128] In another embodiment of the present application, the electronic device may include both physical controls and virtual controls to provide the user with more choices, but the present application does not limit this and it depends on the specific circumstances.

[0129] Based on any of the above embodiments, in one embodiment of the present application, the processing component is further used to: when the target object is located within the signal collection range of the first microphone, if the sound signal collected by the first microphone includes other signals in addition to the target signal, generate the first instruction and the second instruction to use the first microphone to collect the sound signal, and perform noise cancellation processing based on the sound signal collected by the second microphone, wherein the target signal is the sound signal of the target object.

In this embodiment, the second microphone 20 is located between the two first microphones 10, so that the first microphone 10 and the second microphone 20 are arranged at intervals.

[0137] It should be noted that, when the electronic device includes three microphones, compared with the structure of one first microphone and two second microphones in FIG. 4 , the structure of two first microphones and one second microphone in FIG. 5 has lower cost.

[0138] In another embodiment of the present application, the electronic device has four microphones, specifically two first microphones and two second microphones. As shown in FIG6 and FIG7 , the first microphones 10 and the second microphones 20 are arranged at intervals.

[0141] The electronic device provided in the embodiment of the present application includes a first microphone and a second microphone with two microphones having different pickup ranges. Therefore, in different application scenarios, different microphones can be used to collect signals by responding to different first instructions or second instructions, thereby avoiding the high cost and high sealing requirements of the electronic device caused by using an algorithm to process the signal collected by the omnidirectional microphone to achieve sound collection in a specific direction, thereby reducing the cost of the electronic device and reducing the sealing requirements when manufacturing the electronic device.

[0142] Moreover, in the electronic device provided in the embodiment of the present application, the electronic device includes two microphones with different pickup ranges, namely a first microphone and a second microphone, and the cost of the first microphone is less than the cost of the second microphone, thereby further reducing the cost of the electronic device while having the same number of microphones in the electronic device.
