A mobile phone is an electronic device equipped with a cellular communication module.

[0026] See also Figure 1 , Figure 1 It is a structural schematic block diagram of an electronic device 100 in some embodiments of the present application. The electronic device provided by the present application is a foldable electronic device, for example, it can be: a mobile phone, a tablet computer, a smart watch and other electronic devices. Its main advantage is that it combines entertainment and office work, and is easy to carry, which caters to the current consumer demand for portability and diverse functions.

[0027] Among them, the electronic device 100 may include a processor 101, an external memory interface 102, an internal memory 103, a universal serial bus (USB) interface 104, a first antenna 1051, a second antenna 1052, a mobile communication module 106, a wireless communication module 107, an audio module 108, a speaker 1081, a receiver 1082, a microphone 1083, a vibrator 1084, an earphone interface 1085, and a sensor module 109, etc.

[0028] It is understandable that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0029] The processor 101 may include one or more processing units, for example, the processor 101 may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Different processing units may be independent devices or integrated into one or more processors.

[0030] The processor 101 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 101 is a cache memory. The memory may store instructions or data that the processor 101 has just used or cyclically used. If the processor 101 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 101, and thus improves the efficiency of the system.

[0031] In some embodiments, the processor 101 may include one or more interfaces. The interface may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

[0032] Furthermore, the wireless communication function of the electronic device 100 can be implemented by the first antenna 1051, the second antenna 1052, the mobile communication module 106, the wireless communication module 107, the modulation and demodulation processor, and the baseband processor. Among them, the first antenna 1051 and the second antenna 1052 are used to transmit and receive electromagnetic wave signals. Each antenna in the electronic device 100 can be used to cover a single or multiple communication frequency bands. Different antennas can also be reused to improve the utilization of the antenna. For example, the first antenna 1051 can be reused as a diversity antenna of a wireless local area network. In some other embodiments, the antenna can be used in combination with a tuning switch.

[0033] Among them, the mobile communication module 106 can provide solutions for wireless communications including 2G, 3G, 4G, and / or 5G applied to the electronic device 100. The mobile communication module 106 may include at least one filter, a switch, a power amplifier, a low noise amplifier (LNA), etc. The mobile communication module 106 can receive electromagnetic waves through the first antenna 1051, and filter, amplify, and process the received electromagnetic waves, and transmit them to the modulation and demodulation processor for demodulation. The mobile communication module 106 can also amplify the signal modulated by the modulation and demodulation processor, and convert it into electromagnetic waves for radiation through the first antenna 1051. In some embodiments, at least some of the functional modules of the mobile communication module 106 can be set in the processor 101. In some embodiments, at least some of the functional modules of the mobile communication module 106 can be set in the same device as at least some of the modules of the processor 101.

[0034] Among them, the wireless communication module 107 can provide wireless communication solutions including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), and / or infrared (IR) technology applied to the electronic device 100. The wireless communication module 107 can be one or more devices integrating at least one communication processing module. The wireless communication module 107 receives electromagnetic waves via the second antenna 1052, modulates the frequency of the electromagnetic wave signal and filters it, and sends the processed signal to the processor 101. The wireless communication module 107 can also receive the signal to be sent from the processor 101, modulate the frequency, amplify it, and convert it into electromagnetic waves for radiation through the second antenna 1052.

[0035] In some embodiments, the first antenna 1051 of the electronic device 100 is coupled to the mobile communication module 106, and the second antenna 1052 is coupled to the wireless communication module 107, so that the electronic device 100 can communicate with the network and other devices through wireless communication technology. The wireless communication technology may include global system for mobile communications (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division code division multiple access (TD-SCDMA), long term evolution (LTE), BT, GNSS, WLAN, NFC, FM, and / or IR technology. GNSS may include GPS, global navigation satellite system (GLONASS), Beidou navigation satellite system (BDS), quasi-zenith satellite system (QZSS), and / or satellite-based augmentation systems (SBAS).

[0036] The electronic device 100 implements the display function through a GPU, a display screen 1091, and an application processor. The GPU is a microprocessor for image processing, which connects the display screen 1091 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 101 may include one or more GPUs, which execute program instructions to generate or change display information.

[0037] The display screen 1091 is used to display images and / or videos, etc. The display screen 1091 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), Mini-LED, Micro-Led, and / or a quantum dot light emitting diode (QLED), etc. In some embodiments, the electronic device 100 may include 1 or N display screens 1091, where N is a positive integer greater than 1.

[0038] The electronic device 100 can realize the shooting function through the ISP, the camera 1092, the video codec, the GPU, the display screen 1091 and the application processor.

[0039] The ISP is used to process the data fed back by the camera 1092. For example, when taking a photo, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converts it into an image visible to the naked eye. The ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. The ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, the ISP can be set in the camera 1092.

[0040] The camera 1092 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element may be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the electronic device 100 may include 1 or N cameras 1092, where N is a positive integer greater than 1.

[0041] The digital signal processor is used to process digital signals, and can process not only digital image signals but also other digital signals. For example, when the electronic device 100 is selecting a frequency point, the digital signal processor is used to perform Fourier transform on the frequency point energy.

[0042] Video codecs are used to compress or decompress digital videos. The electronic device 100 may support one or more video codecs. Thus, the electronic device 100 may play or record videos in a variety of coding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, and / or MPEG4.

[0043] The external memory interface 102 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the mobile phone. The external memory card communicates with the processor 101 through the external memory interface 102 to implement a data storage function. For example, files such as music and videos are stored in the external memory card.

[0044] The internal memory 103 can be used to store computer executable program codes, which include instructions. The processor 101 executes various functional applications and data processing of the electronic device 100 by running the instructions stored in the internal memory 103. The internal memory 103 may include a program storage area and a data storage area. Among them, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area can store data created during the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the internal memory 103 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, and / or a universal flash storage (UFS), etc.

[0045] The electronic device 100 can implement audio functions such as music playing and recording through the audio module 108 , the speaker 1081 , the receiver 1082 , the microphone 1083 , the vibrator 1084 , the headphone interface 1085 , and the application processor.

[0046] The audio module 108 is used to convert digital audio information into analog audio signal output, and is also used to convert analog audio input into digital audio signal. The audio module 108 can also be used to encode and decode audio signals. In some embodiments, the audio module 108 can be arranged in the processor 101, or some functional modules of the audio module 108 can be arranged in the processor 101.

[0047] The speaker 1081 , also called a “speaker”, is used to convert an audio electrical signal into a sound signal. The electronic device 100 can listen to music or listen to a hands-free call through the speaker 1081 .

[0048] The receiver 1082, also called a "earpiece", is used to convert audio electrical signals into sound signals. When the electronic device 100 receives a call or voice message, the voice can be received by placing the receiver 1082 close to the human ear.

[0049] Microphone 1083, also called "microphone" or "microphone", is used to convert sound signals into electrical signals. When making a call or sending a voice message, the user can make a sound by putting his mouth close to microphone 1083 to input the sound signal into microphone 1083. The electronic device 100 can be provided with at least one microphone 1083. In other embodiments, the electronic device 100 can be provided with two microphones 1083, which can not only collect sound signals but also realize noise reduction function. In other embodiments, the electronic device 100 can also be provided with three, four or more microphones 1083 to realize sound signal collection, noise reduction, and can also identify the sound source to realize directional recording function, etc.

[0050] The vibrator 1084 can generate an inverse piezoelectric effect under the action of a driving voltage, thereby expanding and contracting, and then drive the relevant components on the electronic device 100 to vibrate and make sounds. For example, the vibrator 1084 can drive the display screen of the electronic device 100 to vibrate and make sounds under the action of a driving voltage. For another example, the vibrator 1084 can drive the outer shell (such as a battery cover, or a shell such as a frame) or the screen of the electronic device 100 to vibrate and make sounds under the action of a driving voltage. Among them, the vibrator 1084 can use a common piezoelectric ceramic exciter, a voice coil exciter, or other devices that can generate controllable vibrations.

[0051] The earphone interface 1085 is used to connect a wired earphone and can be a USB interface 130, or a 3.5 mm open mobile terminal platform (OMTP) standard interface, and / or a cellular telecommunications industry association of the USA (CTIA) standard interface.

[0052] The sensor module 109 may include a pressure sensor, a gyroscope sensor, an air pressure sensor, a magnetic sensor, an acceleration sensor, a distance sensor, a proximity light sensor, a fingerprint sensor, a temperature sensor, a touch sensor, an ambient light sensor, a bone conduction sensor, and the like.

[0053] Of course, the electronic device 100 may also include a charging management module, a power management module, a battery, a button, an indicator, and one or more SIM card interfaces, etc., and the present application embodiment does not impose any restrictions on this. The electronic device 100 in the present application embodiment can be applied to various sound output scenarios, such as voice calls, playing audio and video content, etc.

[0054] See also Figure 2 and Figure 3 , Figure 2 is a schematic diagram of the structure of the electronic device 200 when it is flattened in some other embodiments of the present application, Figure 3 yes Figure 2 Schematic diagram of the structure of the electronic device 200 when folded in the embodiment. The electronic device 200 may include a first body 210 and a second body 220 that can rotate relative to each other, that is, the first body 210 and the second body 220 are rotatably connected. The joint between the first body 210 and the second body 220 may be made of a foldable material, so that the first body 210 and the second body 220 can rotate relative to each other.

[0055] In one embodiment, the electronic device 200 may further include a rotating assembly 230, and the first body 210 and the second body 220 are respectively connected to two sides of the rotating assembly 230, so that the second body 220 can be folded or unfolded relative to the first body 210 through the rotating assembly 230. When the electronic device 100 is in a folded state, the volume is relatively small, which is convenient for storage and carrying.

[0056] like Figure 2 and Figure 3 As shown, the angle between the first body 210 and the second body 220 may range from 0° to 180°. When the angle between the first body 210 and the second body 220 is 180°, the electronic device 100 is as shown in FIG. Figure 2 When the angle between the first body 210 and the second body 220 is 0°, the electronic device 200 is in the flattened state as shown. Figure 3 Shown in folded state.

[0057] The rotating assembly 230 may be a hinge assembly, a shaft assembly, or an elastic assembly, etc. The first body 210 and the second body 220 connected to both sides of the rotating assembly 230 may realize relative rotation through the rotating assembly 230. The specific structural and technical features of the rotating assembly 230 are within the scope of understanding of those skilled in the art, so they will not be described in detail.

[0058] Of course, in other embodiments, the electronic device 200 can eliminate the rotating assembly 230, that is, the first body 210 and the second body 220 are directly rotatably connected. For example, the joint portion of the first body 210 and the second body 220 is a retractable structure or a flexible structure, so that the first body 210 and the second body 220 can rotate relative to each other.

[0059] Optionally, the electronic device 200 may be an electronic device that can be folded horizontally or vertically. Figure 2 and Figure 3 2 shows a case where the folding direction of the electronic device 200 is horizontal, and the display screen of the electronic device 200 has two left and right display areas by horizontal folding. It is understandable that the folding direction of the electronic device 200 can also be vertical, and the display screen of the electronic device 200 has two upper and lower display areas by vertical folding. The embodiment of the present application does not specifically limit the folding direction of the electronic device 200.

[0060] It should be noted that the terms "first", "second", etc. in the embodiments of the present application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include at least one of the features.

[0061] See also Figure 4 and Figure 5 , Figure 4 is a schematic diagram of the structure of the electronic device 200 when it is flattened in some other embodiments of the present application, Figure 5 yes Figure 4 Schematic diagram of the structure of the electronic device 200 when folded in the embodiment. The electronic device 200 may include a first body 210 and a second body 220 that can rotate relative to each other, that is, the first body 210 and the second body 220 are rotatably connected. The joint between the first body 210 and the second body 220 may be made of a foldable material, so that the first body 210 and the second body 220 can rotate relative to each other.

[0062] In one embodiment, the electronic device 200 may further include a rotating assembly 230, and the first body 210 and the second body 220 are respectively connected to two sides of the rotating assembly 230, so that the second body 220 can be folded or unfolded relative to the first body 210 through the rotating assembly 230. When the electronic device 200 is in a folded state, the volume is relatively small, which is convenient for storage and carrying.

[0063] It can be understood that the difference between the electronic device 200 of this embodiment and the electronic device 200 in the previous embodiment is that the folding directions of the two are different. That is, the folding direction of the electronic device 200 in this embodiment is vertical. Therefore, the technical features of the electronic device 200 in this embodiment that are not fully described in detail can refer to the relevant description of the electronic device 200 in the previous embodiment, and will not be repeated.

[0064] It should be noted that the electronic devices in the embodiments of the present application are mainly electronic devices with folding screens, such as folding screen mobile phones. Specifically, folding screen mobile phones have gradually become the development trend of future complete machines. The main advantage they bring is that they combine entertainment and office work, and are easy to carry, which caters to the current consumer demand for portability and diverse functions. Among them, folding screen mobile phones generally have folding methods such as inward folding and outward folding. For folding screen mobile phones with inward folding, after folding, the display surfaces of the flexible screen are close to each other along the folding area, that is, the flexible screen is in a folding form that folds inward. For folding screen mobile phones with outward folding, after folding, the display surfaces of the flexible screen are away from each other along the folding area, that is, the flexible screen is in a folding form that folds outward.

[0065] However, for foldable screen mobile phones that fold inward, the flexible screen is not exposed after folding. When a call comes in, the user needs to open the phone to answer it, which is a cumbersome operation.

[0066] Combined with reference Figures 2 to 5 , the electronic device 200 may further include a first display screen 240, which may be a flexible display screen. The first display screen 240 may be connected to the first body 210 and the second body 220 respectively, so that when the first body 210 and the second body 220 rotate relative to each other, the first display screen 240 can be synchronously folded, thereby enabling the first display screen 240 to switch between a folded state and a flattened state. In other words, the first display screen 240 can be synchronously folded with the rotation of the first body 210 and the second body 220, so that the first display screen 240 can switch between a folded state and a flattened state. When the first body 210 and the second body 220 rotate toward each other, the first display screen 240 synchronously switches from a flattened state to a folded state. When the first body 210 and the second body 220 rotate away from each other, the first display screen 240 synchronously switches from a folded state to a flattened state.

[0067] The two ends of the first display screen 240 can be connected to the first body 210 and the second body 220 respectively by bonding or snapping.

[0068] In one embodiment, the electronic device 200 may further include a sound generating component 260, which is configured to generate sound under the control of a control device of the electronic device 200 to meet user needs. The control device may be the processor in the above embodiment.

[0069] The sound-emitting component 260 may include at least one speaker, for example, the sound-emitting component 260 may include a first speaker 261 and / or a second speaker 262. The first speaker 261 and the second speaker 262 may emit sound individually or in coordination under the control of the control device to provide different sound output modes and different usage experiences for the electronic device 200.

[0070] Specifically, when the sound receiving effect does not need to be considered, that is, when the sound output mode of the electronic device 200 is the external speaker mode, the control device of the electronic device 200 can control at least one speaker to emit sound to achieve external sound. For example, the control device of the electronic device 200 can control one of the first speaker 261 and the second speaker 262 to emit sound alone or in combination to meet the needs of different usage scenarios.

[0071] In one embodiment, the sound-generating component 260 may further include at least one vibrator 263, which may drive the housing (such as a battery cover or a frame) and / or the screen of the electronic device 200 to vibrate and generate sound under the control of the control device.

[0072] Specifically, out of consideration for the sound reception effect, in order to prevent the sound emitted by the speaker from leaking into the environment, only the above-mentioned vibrator 263 can be used to achieve vibration sounding without sounding through the first speaker. At this time, the user only receives the sound emitted by the vibration, which ensures the privacy of the user. Of course, in some embodiments, the speaker and the vibrator 263 can be used in combination, so that the audio signal leaked from the speaker can be offset by the audio signal generated by the vibrator 263, thereby ensuring the privacy of the user.

[0073] The electronic device 200 with the speaker and the vibrator 263 in the above embodiment can provide at least two sound output modes for the user when working: an external speaker mode or a privacy mode.

[0074] In the privacy mode, the sound output by the electronic device 200 is required to be less leaked but can be clearly heard by the user. Therefore, the vibrator 263 can be used in the electronic device 200 to achieve vibration sound. Since the vibrator 263 is set close to the user's ear, the position of the vibration sound is also close to the user's ear, and the sound can naturally be received by the user in large quantities. This can avoid the problem of partial sound leakage caused by using a speaker to produce sound.

[0075] In some embodiments of the privacy mode, in addition to using the vibrator 263 to achieve vibration sound, the electronic device 200 can also make the speaker (such as the first speaker 261 and / or the second speaker 262) work to make sound. However, it is necessary to ensure that the audio signal leaked from the speaker can be offset as much as possible by the audio signal generated by the vibration of the vibrator 263, so as to avoid the problem of partial sound leakage caused by using the speaker to make sound. Optionally, in the privacy mode, the vibrator 263 can make sound together with the first speaker 261 or the second speaker 262, that is, the audio signal emitted by the vibrator 263 can offset the audio signal leaked from the first speaker 261 or the second speaker 262. Optionally, in the privacy mode, both the first speaker 261 and the second speaker 262 can make sound. At this time, the vibrator 263 can be provided with two, and the audio signal emitted by one vibrator 263 can offset the audio signal leaked from the first speaker 261, and the audio signal emitted by the other vibrator 263 can offset the audio signal leaked from the second speaker 262.

[0076] It can be understood that the above embodiment only exemplarily lists the manner in which the vibrator and the speaker make sounds together in the privacy mode, but is not limited thereto.

[0077] In the external speaker mode, the sound output by the electronic device 200 is required to be loud enough so that the user can hear it clearly without picking up the electronic device 200. Therefore, the electronic device 200 can use only the speaker to make sounds. When the first speaker 261 and the second speaker 262 make sounds separately, the volume of the sounds made by the first speaker 261 and the second speaker 262 can be increased by adjusting the power of the first speaker 261 and the second speaker 262, and finally the sounds made are sent to the user. Optionally, when the first speaker 261 and the second speaker 262 cooperate to make sounds, the first speaker 261 and the second speaker 262 can cooperate to make sounds to provide the user with a balanced stereo effect and enhance the sound experience.

[0078] In one embodiment, the first speaker 261 may be disposed on the first body 210 , and the second speaker 262 may be disposed on the second body 220 . That is, the first speaker 261 and the second speaker 262 are disposed on both sides of the extending direction of the rotating assembly 230 .

[0079] The vibrator 263 may be disposed on the first body 210 and / or the second body 220, and disposed on a side of the non-display surface of the first display screen 240. The vibrator 263 may drive the first display screen 240 to vibrate to produce sound under the control of the control device, or the vibrator 263 may drive the first body 210 or the second body 220 to vibrate to produce sound under the control of the control device. Those skilled in the art may flexibly select according to actual needs, and no further details are given.

[0080] As mentioned above, the electronic device 200 can have a folded state and an unfolded state. Therefore, in different states and different sound output modes of the electronic device 200, the sound component 260 can use different sound output methods to meet the user's usage needs, thereby improving the user experience.

[0081] Among them, in the external speaker mode, the control device can control at least one speaker to sound to meet the user's usage needs. Further, when the user does not have high requirements for sound effects, the control device can control one or part of the multiple speakers to sound, for example, the control device can control the first speaker 261 or the second speaker 262 to sound. When the user has high requirements for sound effects, the control device can control the first speaker 261 and the second speaker 262 to cooperate to form stereo to enhance the user experience.

[0082] Optionally, in the external speaker mode and the unfolded state of the electronic device 200, the control device can control at least one speaker to make a sound to meet the user's usage needs. Further, when the user does not have high requirements for sound effects, the control device can control one or part of the multiple speakers to make a sound, for example, the control device can control the first speaker 261 or the second speaker 262 to make a sound. When the user has high requirements for sound effects, the control device can control the first speaker 261 and the second speaker 262 to cooperate to form a stereo to enhance the user experience.

[0083] It can be understood that when the first speaker 261 and the second speaker 262 cooperate to form a stereo, one of them can input a first channel signal and the other can input a second channel signal. The first channel signal is a left channel signal and the second channel signal is a right channel signal. In addition, in some embodiments, the first channel signal is a right channel signal and the second channel signal is a left channel signal.

[0084] Optionally, in the external speaker mode and folded state of the electronic device 200, the first speaker 261 and the second speaker 262 are respectively intersected, overlapped, or arranged side by side in the orthographic projection areas on the display surface of the first display screen 240, that is, at this time, the distance between the first speaker 261 and the second speaker 262 is relatively close, and the sound of different channel signals emitted by the two speakers at the same time will cause interference. Based on this, the control device can separately control the sound of the first speaker 261 or the second speaker 262 to avoid interference, so as to ensure that the user can obtain a normal sound experience.

[0085] Of course, in other embodiments, the control device may perform mixing processing on the audio signal of the electronic device 200 and then play it through the first speaker 261 and / or the second speaker 262 to ensure that the user can obtain a normal sound experience. Specifically, the first channel signal may be input to one of the first speaker 261 and the second speaker 262, and the second channel signal may be input to the other of the first speaker 261 and the second speaker 262. The control device may perform mixing processing on the first channel signal and the second channel signal in advance, and then input them to the first speaker 261 and / or the second speaker 262 to achieve corresponding audio playback, thereby avoiding interference.

[0086] In one embodiment, in the privacy mode, the user has a high requirement for the privacy of the sound effect. The control device can control the speaker and the vibrator to cooperate in making a sound, or control the vibrator to vibrate to make a sound, so as to protect the privacy of the user while maintaining the quality of the sound effect.

[0087] Optionally, in the privacy mode and unfolded state of the electronic device 200, the control device can control the speaker and the vibrator to cooperate in making sounds to protect the privacy of the user. Specifically, in the privacy mode, the user needs to hold the electronic device 200 close to the face or head to receive the sound, that is, the speaker and / or the vibrator are close to the user's ear. When a single speaker is used to make sounds near the user's ear, the sound emitted by the speaker will leak, thereby leaking the user's privacy. Therefore, the embodiment of the present application controls the speaker and the vibrator to cooperate in making sounds, so that the vibration pronunciation of the vibrator can offset the audio signal leaked from the speaker, thereby protecting the privacy of the user.

[0088] Further, the vibrator may be provided on the first body to cooperate with the first speaker to produce sound. Of course, in other embodiments, the vibrator may be provided on the second body to cooperate with the second speaker to produce sound. In addition, in some embodiments, two vibrators may be provided on the first body and the second body, respectively, and cooperate with the first speaker and the second speaker to produce sound, respectively.

[0089] like Figures 2 to 5 As shown, in the external speaker mode, the positional relationship between the speaker and the user's ear does not need to be clearly defined. In the privacy mode, the speaker or vibrator needs to be close to the user's ear to make a sound, thereby protecting the user's privacy. Based on this, in the unfolded state of the electronic device, when the user holds the electronic device to pick up sound, the first speaker or the second speaker is close to the user's ear. In the folded state of the electronic device, when the user holds the electronic device to pick up sound, the vibrator is close to the user's ear.

[0090] Optionally, in the unfolded state and privacy mode of the electronic device, when the vibrator and the first speaker are both located on the first body, the first body is configured as an electronic device for use close to the user's ear. When making a sound, the audio signal of the vibrator and the audio signal of the first speaker are in opposite phases to offset the audio signal leaked from the first speaker, thereby protecting the user's privacy.

[0091] Optionally, in the unfolded state and privacy mode of the electronic device, when the vibrator and the second speaker are both located on the second body, the second body is configured as an electronic device for use close to the user's ear. When making a sound, the audio signal of the vibrator and the audio signal of the second speaker are in opposite phases to offset the audio signal leaked from the second speaker, thereby protecting the user's privacy.

[0092] Optionally, in the privacy mode and folded state of the electronic device 200, the control device controls the vibrator to vibrate to achieve sound, thereby protecting the privacy of the user. The vibrator may be located inside the first body or the second body to drive the first body or the second body to vibrate and make sound. When the user picks up the electronic device 200 and holds it close to the face or head to receive sound, the position of the vibrator is close to the user's ear, and the sound emitted by the first body or the second body vibrating can be received by the user.

[0093] As mentioned above, when the angle between the first body 210 and the second body 220 is 180°, the electronic device 100 is as follows: Figure 2 When the angle between the first body 210 and the second body 220 is 0°, the electronic device 200 is in the flattened state as shown. Figure 3 When the angle between the first body 210 and the second body 220 is an angle other than 0° and 180°, the electronic device 200 can be in a hovering state (not shown in the figure). When the electronic device 200 is in the hovering state, the sound output mode of the electronic device 200 is usually an external speaker mode. The specific implementation method can refer to the external speaker mode in the aforementioned embodiment, so it will not be described in detail.

[0094] See also Figure 6 , Figure 6 2 is a schematic diagram of the structure of the electronic device 200 when it is folded in some other embodiments of the present application. The electronic device 200 may include a first display screen 240 and a second display screen 270 arranged opposite to each other. The first display screen 240 can be folded synchronously with the electronic device 200, that is, the first display screen 240 can be a flexible screen. When the electronic device 200 is in the unfolded state, the first display screen 240 is located on the same side of the first body 210 and the second body 220, and the second display screen 270 is located on the side of the first body 210 and the second body 220 away from the first display screen 240.

[0095] The second display screen 270 may be disposed on the first body 210 or the second body 220. When the electronic device 200 is in the unfolded state, the first display screen 240 is preferably used for display, and the second display screen 270 may be used for display. When the electronic device 200 is in the folded state, since the first display screen 240 is hidden inside the electronic device 200, the second display screen 270 is used for display. In other words, when the electronic device 200 is in the folded state, the second display screen 270 can display.

[0096] In one embodiment, the second display screen 270 is disposed on a side of the first body 210 away from the first display screen 240, and the vibrator 263 is disposed on the first body 210, so that when the vibrator 263 vibrates, it can drive the first body 210 to vibrate to achieve sound, or when the vibrator 263 vibrates, it can drive the second display screen 270 to vibrate to achieve sound.

[0097] In one embodiment, the second display screen 270 is disposed on a side of the second body 220 away from the first display screen 240, and the vibrator 263 is disposed on the second body 220, so that the vibrator 263 can drive the second body 220 to vibrate to achieve sound when vibrating, or the vibrator 263 can drive the second display screen 270 to vibrate to achieve sound when vibrating.

[0098] See also Figure 7 , Figure 7 2 is a schematic diagram of the structure of the electronic device 200 when it is unfolded in some other embodiments of the present application. The first speaker 261 can be arranged on the end of the first body 210 away from the second body 220, that is, the first speaker 261 can be arranged on the top of the electronic device 200 when it is unfolded; the second speaker 262 can be arranged on the end of the second body 220 away from the first body 210, that is, the second speaker 262 can be arranged on the bottom of the electronic device 200 when it is unfolded. The control device of the electronic device 200, that is, the processor, can control the first speaker 261 and / or the second speaker 262 to make a sound. The second display screen 270 and the vibrator 263 are arranged on the second body 220, and the vibrator 263 is arranged on the side of the second display screen 270 close to the rotating assembly 230, so as to drive the second body 220 to vibrate under the control of the control device of the electronic device 200, that is, the processor, to achieve sound. Of course, in other implementations, the orthographic projection areas of the vibrator 263 and the second display screen 270 on the second body 220 intersect or overlap, so that the vibration of the vibrator 263 can drive the second display screen 270 to vibrate to produce sound.

[0099] See also Figure 8 , Figure 82 is a schematic diagram of the structure of the electronic device 200 when it is unfolded in some other embodiments of the present application. The vibrator 263 may include a first vibrator 2631 disposed on the first body 210 and a second vibrator 2632 disposed on the second body 220 .

[0100] In the privacy mode of the electronic device 200, when the electronic device 200 is in the unfolded state, the control device controls the first vibrator 2631 and the first speaker 261 to cooperate to make a sound, or the control device controls the second vibrator 2632 and the second speaker 262 to cooperate to make a sound.

[0101] In the privacy mode of the electronic device 200 , when the electronic device 200 is in a folded state, the control device controls the first vibrator 2631 or the second vibrator 2632 to vibrate to produce sound.

[0102] Optionally, two second display screens 270 may be provided, and the two second display screens 270 are respectively provided on the first body 210 and the second body 220, and can display independently.

[0103] See also Fig. 9 , Fig. 9 2 is a schematic diagram of the control system structure in the electronic device 200 in some embodiments of the present application. A control device 280 may be provided in the electronic device 200. The control device 280 may be a microcontroller unit (MCU), or may be other control circuits or structures including a processor, which will not be described in detail. The control device 280 is used to control the channel signal to be input to any one of the first speaker 261, the second speaker 262, and the vibrator 263, so as to complete the sound control of the electronic device 200.

[0104] In some embodiments, the electronic device 200 also includes an I2C bus 281 and an I2S bus 282 electrically connected to the control device 280, a first power amplifier 283 electrically connected to the first speaker 261, the I2C bus 281 and the I2S bus 282 respectively, a second power amplifier 284 electrically connected to the second speaker 262, the I2C bus 281 and the I2S bus 282 respectively, and a third power amplifier 285 electrically connected to the vibrator 263, the I2C bus 51 and the I2S bus 282 respectively.

[0105] The control device 280 is electrically connected to the first power amplifier 283, the second power amplifier 284, and the third power amplifier 285 through the I2C bus 281 to control the on and off of any one of the first power amplifier 283, the second power amplifier 284, and the third power amplifier 285. The control device 280 is electrically connected to the first power amplifier 283, the second power amplifier 284, and the third power amplifier 285 through the I2S bus 282 to transmit audio data such as channel signals (left channel signal, right channel signal) to any one of the first power amplifier 283, the second power amplifier 284, and the third power amplifier 285.

[0106] In some embodiments, based on the control device 280, I2C bus 281, I2S bus 282, first power amplifier 283, second power amplifier 284, and third power amplifier 285, the control device 280 controls the speaker to emit sound externally, and can also control the vibrator to achieve external sound emission through vibration.

[0107] In some embodiments, based on the control device 280, the I2C bus 281, the I2S bus 282, the first power amplifier 283, the second power amplifier 284, and the third power amplifier 285, the control device 280 can control the speaker to make a sound based on the sound output mode of the electronic device 200, and / or control the vibrator to vibrate to achieve sound when the first body 210 and the second body 220 are in the unfolded state. Further, the control device 280 can also control the speaker to make a sound based on the sound output mode of the electronic device 200, and / or control the vibrator to vibrate to achieve sound when the first body 210 and the second body 220 are in the folded state. Please refer to the above embodiments for details.

[0108] In some embodiments, the electronic device 200 also includes a sensor (such as the sensor module 109 in the aforementioned embodiment), which can be used to measure the angle between the plane where the first body 210 is located and the plane where the second body 220 is located, so as to better obtain the relative position posture of the first body 210 and the second body 220, that is, the posture of the electronic device 200. The control device 280 then controls the first power amplifier 263, the second power amplifier 264, and the third power amplifier 265, or controls the first speaker 261, the second speaker 262, and the vibrator 263 when determining whether the relative position posture is in a folded state or an unfolded state.

[0109] The present application solves the problem caused by the speaker making sound alone by setting a speaker and a vibrator to make sound together, so as to protect the user's privacy when necessary.

[0110] Next, an audio control method is described. The method can be used in the electronic device in the above embodiment to control the first speaker, the second speaker and the vibrator.

[0111] For example, the method can control a speaker to emit sound, or control a vibrator to vibrate to achieve sound, or control at least one speaker to cooperate to form stereo, or control at least one vibrator and at least one speaker to cooperate to offset sound leakage of the speaker.

[0112] See also Fig.10 , Fig.10 : is a flowchart of an audio control method in an embodiment of the present application. The audio control method may include the following steps:

[0113] Step S1001: Determine the posture and sound output mode of the electronic device.

[0114] Among them, the posture of the electronic device can be realized by the above-mentioned sensor. The sound output mode of the electronic device can be set based on the preset scene. For example, in a personal independent space, there is no worry about privacy leakage, and the sound output mode can be an external speaker mode. For another example, there is a risk of privacy leakage in a public space, and the sound output mode can be a privacy mode. Specifically, whether there is a risk of privacy leakage can be determined based on parameters such as the sensed ambient light brightness or the ambient noise level.

[0115] Step S1002: controlling the speaker to produce sound and / or controlling the vibrator to vibrate to produce sound according to the posture and sound output mode of the electronic device.

[0116] Among them, the sound output mode of the electronic device includes an external speaker mode and a privacy mode. In the external speaker mode, at least one speaker is controlled to make a sound. In the privacy mode, when the electronic device is in an unfolded state, the speaker and the vibrator are controlled to cooperate to make a sound; when the electronic device is in a folded state, the vibrator is controlled to vibrate to achieve the sound. For details, please refer to the above embodiment, which will not be repeated here.

[0117] In addition, when the electronic device is in a hovering state, the sound output mode of the electronic device is generally an external speaker mode. The specific implementation method can refer to the external speaker mode in the aforementioned embodiment and will not be described in detail.

[0118] In one embodiment, the speaker includes a first speaker and a second speaker. That is, the audio control method in the external speaker mode may include:

[0119] When the electronic device is in the unfolded state, controlling one of the first speaker and the second speaker to input the first channel signal and the other to input the second channel signal to cooperate to form stereo sound;

[0120] When the electronic device is in the folded state, the audio signal of the electronic device is mixed and then played through the first speaker and / or the second speaker.

[0121] In one embodiment, the speaker includes a first speaker and a second speaker. That is, the audio control method in the privacy mode may include:

[0122] When the electronic device is in the unfolded state, the phases of the audio signal of the vibrator and the audio signal of the speaker are controlled to be opposite to each other, so as to offset the sound leakage of the speaker and thus protect the privacy of the user.

[0123] It can be understood that the technical features not fully described in this embodiment can refer to the specific description in the previous embodiments, so they will not be described in detail again.

[0124] The electronic device and audio control method provided in the embodiments of the present application selectively realize sound generation by controlling the speaker and the vibrator to meet the different usage requirements of the user. At the same time, in the usage scenario where the user needs to protect the privacy, the user's privacy can be protected by the vibrator and the speaker cooperating to generate sound or the vibrator vibrating to generate sound.

[0125] The present application embodiment also provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program for electronic data exchange, and the computer program enables the computer to execute some or all steps of any method as recorded in the above method embodiment. It can be understood that the above computer includes an electronic device.
