[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0032] The electronic device and the control method thereof provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0033] refer to Figures 1 to 4 The embodiment of the present application discloses an electronic device, including a device body 100, a display screen 200, a camera module and a sound detection component. The device body 100 is provided with a first sound pickup hole 110, the display screen 200 is arranged on the device body 100, the camera module and the sound detection component are both arranged in a receiving space surrounded by the device body 100 and the display screen 200, and the sound detection component is connected to the first sound pickup hole 110 to detect whether the first sound pickup hole 110 is blocked, that is, the sound detection component is used to detect the sound signal transmitted into the first sound pickup hole 110, and judge whether the first sound pickup hole 110 is blocked according to the change amplitude of the sound signal. The device body 100 includes a first main body 120 and a second main body 130 that are rotatably connected, and the display screen 200 includes a first part 210 and a second part 220 that are connected. The first main body 120 can rotate relative to the second main body 130 to change the angle between the first part 210 and the second part 220, that is, the angle between the first part 210 and the second part 220 can be any angle between 0° and 180°. When the angle is 0°, the electronic device is in a folded state; when the angle is 90°, the first main body 120 is perpendicular to the second main body 130; when the angle is 180°, the display screen 200 is in an unfolded state, and its effective display area is large, and it has a good viewing effect. Optionally, the display screen 200 can be a flexible display screen, so that the angle between the first part 210 and the second part 220 can be flexibly changed. When there is an angle (ie, a non-zero angle) between the first portion 210 and the second portion 220 , the camera module is in an on state, and the first sound pickup hole 110 is blocked, the camera module starts shooting or stops shooting.

[0034] In an embodiment of the present application, when there is an angle between the first part 210 and the second part 220, the camera module is in the on state, and it is necessary to start or end shooting, the user only needs to block the first sound pickup hole 110. At this time, the signal amplitude detected by the sound detection component is significantly smaller than before the first sound pickup hole 110 is blocked. The camera module can be controlled to start or stop shooting according to the signal change, thereby avoiding the user from triggering the start / end button located in the screen area, thereby improving the convenience of user shooting. Therefore, the present application can solve the problem of inconvenience in operating the current electronic device during shooting when it is folded to a certain angle. Optionally, the angle here can be 60° to 120°, and the embodiment of the present application is not specifically limited.

[0035] In an optional embodiment, the accommodating space includes a first accommodating cavity and a second accommodating cavity, the first main body 120 and the first part 210 form the first accommodating cavity, the second main body 130 and the second part 220 form the second accommodating cavity, the camera module is arranged in the first accommodating cavity, the sound detection element is arranged in the second accommodating cavity, the first sound pickup hole 110 is opened at one end of the second main body 130 away from the first main body 120, and there is an angle between the first part 210 and the second part 220. When the camera module is in the open state, the first part 210 is used to display the preview picture. During the shooting process of the camera module, the first part 210 is used to provide an effective display picture, the second part 220 and the second main body 130 serve as a support frame to play a supporting role. When the user holds the support frame, since the first sound pickup hole 110 is opened at one end of the second main body 130 away from the first main body 120, the first sound pickup hole 110 is closer to the user's eyes, which is convenient for the user to accurately cover the first sound pickup hole 110. Of course, the first sound pickup hole 110 can also be opened at the end of the second main body 130 close to the first main body 120. In this case, a touchable mark can be set around the first sound pickup hole 110 to facilitate the user to determine the position of the first sound pickup hole 110. However, this will not only affect the aesthetics of the electronic device, but also the convenience of operation is not as good as opening the first sound pickup hole 110 at the end of the second main body 130 away from the first main body 120.

[0036] Further optionally, the first sound pickup hole 110 is opened on the end surface of the second main body 130 away from the first main body 120. When there is an angle between the first part 210 and the second part 220, and the camera module is in the on state, the first part 210 is used to display the preview screen. At this time, the first sound pickup hole 110 is facing the user, which is conducive to the user to clearly see the first sound pickup hole 110 and accurately cover the first sound pickup hole 110.

[0037] Optionally, the sound detection component can be an additional sound sensor or audio analyzer, etc.; in other embodiments, the sound detection component is a microphone of the electronic device, and when the camera module is in a closed state, the microphone is used to obtain sound signals through the first sound pickup hole 110. That is to say, when the camera module is not working, the microphone is used as an acoustic device to obtain sounds in the external environment for calls, etc.; when the camera module is working, the microphone is used as a sound detection component to detect whether the first sound pickup hole 110 is blocked. It can be seen that the sound detection component in the present application is an existing structure in the electronic device. By reusing the existing structure in the electronic device, the effect of one thing serving two purposes is achieved, and there is no need to set up a separate sound detection component, which is conducive to saving the production cost of the electronic device, and at the same time can reduce the difficulty of the internal structural layout of the electronic device.

[0038] Optionally, the sound detection component can be used to detect sounds in the external environment, so as to detect whether the first sound pickup hole 110 is blocked; or, in another optional embodiment, the device body 100 is also provided with a sound outlet hole 140, and the electronic device also includes a sound-generating device, which can be used to emit ultrasonic signals, and the sound-generating device is arranged in the accommodation space, and the sound-generating device is connected to the sound outlet hole 140, and the sound detection component can be used to detect ultrasonic signals. When there is an angle between the first part 210 and the second part 220, and the camera module is in the open state, the sound detection component is used to detect the ultrasonic signal emitted by the electronic device itself, so that the sound detection component can detect specific sound signals in a targeted manner, thereby improving the detection accuracy of the sound detection component.

[0039] In addition, in the above embodiment, when the device body 100 is also provided with a sound outlet hole 140 and the electronic device also includes a sound-emitting device, the user can not only cover the first sound pickup hole 110, but also cover the sound outlet hole 140 to reduce the ultrasonic signal transmitted from the sound outlet hole 140, thereby making the amplitude of the sound signal detected by the sound detection component significantly smaller than before the sound outlet hole 140 is blocked, thereby providing users with more choices to enhance the user experience.

[0040] Optionally, the sound outlet hole 140 and the first sound pickup hole 110 can be set at any interval, and the distance between the two can be relatively far. In this case, the ultrasonic signal detected by the sound detection component is relatively weak. When the sound in the external environment is relatively loud, the detection accuracy of the sound detection component is relatively poor. Based on this, in other embodiments, the sound outlet hole 140 is arranged adjacent to the first sound pickup hole 110. In this case, the distance between the sound outlet hole 140 and the first sound pickup hole 110 is relatively close, and the ultrasonic signal detected by the sound detection component is relatively strong, which is conducive to further improving the detection accuracy of the sound detection component.

[0041] Optionally, the sound-generating device can be an additional device, such as a buzzer, etc.; in another optional embodiment, the sound-generating device is a speaker of an electronic device, and when the camera module is in a closed state, the speaker is used to emit sound signals through the sound outlet 140. When the camera module is not working, the speaker is used as an acoustic device for making calls, listening to music, etc.; when the camera module is working, the speaker is used as a sound-generating device for emitting ultrasonic signals. It can be seen that the sound-generating device in the present application is an existing structure in an electronic device. By reusing the existing structure in the electronic device, the effect of one thing serving two purposes is achieved, and there is no need to set up a separate sound-generating device, which is conducive to saving the production cost of the electronic device, and at the same time can reduce the difficulty of the structural layout inside the electronic device.

[0042] In another optional embodiment, the device body 100 is also provided with a second sound pickup hole 150 spaced apart from the first sound pickup hole 110, and the second sound pickup hole 150 here is not connected to the sound detection part. The electronic device also includes a microphone, which is connected to the second sound pickup hole 150, and has an angle between the first part 210 and the second part 220. When the camera module is in a shooting state, the microphone is used to obtain sound signals through the second sound pickup hole 150. When the camera module is working, the sound detection part detects whether the first sound pickup hole 110 is blocked through the first sound pickup hole 110, and the second sound pickup hole 150 is always connected to the external environment to obtain sound signals in the external environment, so as to avoid the video obtained by the camera module having no sound when the first sound pickup hole 110 is blocked, thereby improving the integrity of the sound pickup during the camera module recording process, and then improving the user experience.

[0043] refer to Figure 5 Based on the electronic device provided in the embodiment of the present application, the embodiment of the present application further provides a control method of the electronic device, which is applied to the electronic device in any of the above embodiments, and the control method includes:

[0044] S100, when there is an angle between the first portion 210 and the second portion 220 and the camera module is in an on state, detecting whether the first sound pickup hole 110 is blocked.

[0045] In this step, a sound detection component can be used to detect whether the first sound pickup hole 110 is blocked. Optionally, the sound detection component can be a microphone of the electronic device. Specifically, when the camera module is not working, the microphone is used as an acoustic device to obtain sounds in the external environment such as calls; when the camera module is working, the microphone is used as a sound detection component to detect whether the first sound pickup hole 110 is blocked. In this case, the sound detection component is an existing structure in the electronic device. By reusing the existing structure, a dual-purpose effect is achieved without the need to set up a separate sound detection component, which is beneficial to saving the production cost of the electronic device and can reduce the difficulty of the internal structural layout of the electronic device.

[0046] S200: When the first sound pickup hole 110 is blocked, control the camera module to start or stop shooting.

[0047] In the embodiment of the present application, when there is an angle between the first part 210 and the second part 220, the camera module is in the open state, and it is necessary to start or end shooting, the user only needs to cover the first sound pickup hole 110. At this time, the signal amplitude detected by the sound detection component is significantly smaller than before the first sound pickup hole 110 is blocked. According to the change of the signal, the camera module can be controlled to start or stop shooting, thereby avoiding the user from triggering the start / end button located in the screen area, thereby improving the convenience of user shooting. Therefore, the present application can solve the problem of inconvenience in operation during shooting of current electronic devices when folded to a certain angle.

[0048] In an optional embodiment, the step S200 of detecting whether the first sound pickup hole 110 is blocked specifically includes:

[0049] S210: Obtain a first signal parameter.

[0050] S220: When the first signal parameter is less than the second signal parameter, and the difference between the second signal parameter and the first signal parameter is greater than a preset value, it is determined that the first sound pickup hole 110 is blocked, wherein the first signal parameter is a parameter of a current sound signal transmitted from the first sound pickup hole 110, and the second signal parameter is a parameter of a sound signal transmitted from the first sound pickup hole 110 before the current sound signal.

[0051] In this solution, by comparing the first signal parameter and the second signal parameter, when the difference between the second signal parameter and the first signal parameter is equal to or less than the preset value, it indicates that the first sound pickup hole 110 is not blocked; when the difference between the second signal parameter and the first signal parameter is greater than the preset value, it indicates that the first sound pickup hole 110 is blocked. In other words, by judging the size of the parameter change value of the sound signal transmitted from the first sound pickup hole 110, it is accurately judged whether the first sound pickup hole 110 is blocked, and then the working state of the camera module is controlled.

[0052] It should be noted that the above-mentioned preset value can be a specific value or a specific range of values, and the embodiments of the present application do not impose any specific limitation.

[0053] Optionally, the first signal parameter may be a parameter of a sound signal transmitted from the first sound pickup hole 110 at the current moment, and the second signal parameter may be a parameter of a sound signal transmitted from the first sound pickup hole 110 at the previous moment; or, in other embodiments, step S210 specifically includes:

[0054] S211. Obtain a first parameter.

[0055] S212. Obtain a first signal parameter according to the first parameter.

[0056] The step S200 of detecting whether the first sound pickup hole 110 is blocked further includes:

[0057] S230: Obtain a second parameter.

[0058] S240. Obtain a second signal parameter according to the second parameter, wherein the first parameter is a parameter of the sound signal transmitted from the first sound pickup hole 110 in the current time period, and the first parameter may be an rms value (i.e., root mean square value) of the sound signal amplitude in the current time period; and the second parameter is a parameter of the sound signal transmitted from the first sound pickup hole 110 in the previous time period, and the second parameter may be an rms value (i.e., root mean square value) of the sound signal amplitude in the previous time period.

[0059] The specific durations of the current time period and the previous time period in this step can be adjusted according to actual needs and are not specifically limited here.

[0060] This solution calculates the rms value of the sound signal amplitude within a certain time period, and compares the rms value in the current time period with the rms value in the previous time period. When the difference between the two is greater than a preset value, it is determined that the first sound pickup hole 110 is blocked, thereby accurately controlling the working state of the camera module to avoid sudden loud noise in the external environment or sudden silence in the external environment, which causes a large difference in the change amplitude of the second signal parameter and the first signal parameter, resulting in false triggering.

[0061] Specific reference Figure 6, time t0 is the time when there is a certain angle between the first part 210 and the second part 220 of the display screen 200 of the electronic device, and the camera module is in the on state, by setting a time period T, taking the rms value of the sound signal amplitude in the time period, assuming that the current time is t, the control system of the electronic device retains the rms value of the sound signal amplitude in the previous time period, that is, the rms value of the sound signal amplitude in the time period t(n-2)~t(n-1); the user blocks the first sound pickup hole 110 at time t, and the rms value of the sound signal amplitude in the time period will become smaller, and the rms value of the sound signal amplitude in the time period t(n-1)~t(n) is compared with the rms value of the sound signal amplitude in the time period t(n-2)~t(n-1). When the rms value decreases by a preset value, it is determined that the user blocks the first sound pickup hole 110, and the user wants the camera module to start or stop shooting.

[0062] In another optional embodiment, in the step of detecting whether the first sound pickup hole 110 is blocked:

[0063] Within a preset time period, when the first signal parameter is smaller than the second signal parameter, and the difference between the second signal parameter and the first signal parameter is greater than a preset value at least twice, it is determined that the first sound pickup hole 110 is blocked.

[0064] In this scheme, within a preset time period, when the first signal parameter is less than the second signal parameter, and the difference between the second signal parameter and the first signal parameter is greater than the preset value only once, it may be caused by the sudden increase or decrease of the sound in the external environment, and is not caused by the first sound pickup hole 110 being blocked; when the first signal parameter is less than the second signal parameter, and the difference between the second signal parameter and the first signal parameter is greater than the preset value at least twice, it is determined that the first sound pickup hole 110 is blocked due to human operation, thereby reducing the probability of false touch, and then accurately controlling the working state of the camera module.

[0065] In another optional embodiment, the electronic device also includes a sound-generating device, which can be used to emit ultrasonic signals. Optionally, the sound-generating device can be a speaker of the electronic device. When the camera module is not working, the speaker is used as an acoustic device for making calls, listening to music, etc. When the camera module is working, the speaker is used as a generating device to emit ultrasonic signals. The sound-generating device is an existing structure in the electronic device. By reusing the existing structure to achieve a dual-purpose effect, there is no need to set up a separate sound-generating device, which is beneficial to saving the production cost of the electronic device and reducing the difficulty of the internal structural layout of the electronic device. The sound detection component can be used to detect ultrasonic signals. Step S210 specifically includes:

[0066] S213, controlling the sound-generating device to emit an ultrasonic signal.

[0067] S214 , eliminating sound signals in frequency bands other than the ultrasonic frequency band from the current sound signal transmitted from the first sound pickup hole 110 to obtain a first target sound signal.

[0068] In this step, not only the ultrasonic signal emitted by the sound-emitting device but also the sound signal in the external environment is transmitted into the first sound pickup hole 110. At this time, the sound signals in frequency bands other than the ultrasonic frequency band in the current sound signal transmitted into the first sound pickup hole 110 need to be eliminated, that is, the sound signals in the external environment transmitted into the first sound pickup hole 110 are eliminated, and the ultrasonic signal emitted by the remaining sound-emitting device is used so that the sound detection component can accurately detect the ultrasonic signal emitted by the sound-emitting device.

[0069] S215. Acquire a first signal parameter according to the first target acoustic signal.

[0070] In this solution, the sound detection component has the function of specifically detecting a specific sound signal, namely, an ultrasonic signal emitted by a sound-emitting device, thereby improving the detection accuracy of the sound detection component.

[0071] In a further optional embodiment, after controlling the camera module to start shooting in step S200, the method further includes:

[0072] S300: Obtain the working mode of the camera module.

[0073] S400: When the working mode is the video recording mode, obtain a video recording sound signal.

[0074] It should be noted that when the camera module is in the photo mode, it is only necessary to preview the image without obtaining the sound signal. Only when the camera module is in the video mode, it is necessary not only to preview the image but also to obtain the video sound signal.

[0075] S500: Eliminate ultrasonic frequency band signals from the video recording sound signal to obtain a second target sound signal.

[0076] In this solution, the first sound pickup hole 110 not only transmits the ultrasonic signal emitted by the sound-emitting device, but also transmits the sound signal in the external environment. When the working mode of the camera module is the video recording mode, it is necessary to eliminate the ultrasonic frequency band in the current sound signal transmitted into the first sound pickup hole 110, and retain the sound signal in the external environment transmitted into the first sound pickup hole 110, so as to avoid the ultrasonic frequency band from affecting the current video, thereby improving the sound clarity of the video.

[0077] In the control method provided in the embodiment of the present application, the execution subject may be a control device. In the embodiment of the present application, the control device of the electronic device provided in the embodiment of the present application is described by taking the control device executing the control method as an example.

[0078] The control device of the electronic device disclosed in the embodiment of the present application can control the camera module to start or stop shooting when the first sound pickup hole 110 is blocked according to the detection module, thereby avoiding the user from triggering the start / end button located in the screen area, thereby improving the convenience of user shooting.

[0079] The control device in the embodiment of the present application can be an electronic device, or a component in the electronic device, such as an integrated circuit or a chip. The electronic device can be a terminal, or other devices other than a terminal.
