Description

Technical Field

[0001] This application relates to the field of terminals and computers, and in particular to an electronic device with a sound leakage prevention function. Background Technology

[0002] Foldable electronic devices are relatively mature in development. In order to enable the call function of foldable electronic devices, an inner screen earpiece gap is usually set in the foldable electronic device. When making a call, the user needs to keep the electronic device in the open state so as to answer the call through the inner screen earpiece gap. The process of answering a call with a foldable electronic device is relatively cumbersome, and it is inevitable to cause sound leakage, resulting in a poor user experience. Summary of the Invention

[0003] This application provides an electronic device with good sound leakage prevention and easy voice call operation.

[0004] In a first aspect, an electronic device is provided. The electronic device includes a first housing, a second housing, a first screen, a second screen, a folding mechanism, a first sound-emitting unit, and a second sound-emitting unit. The folding mechanism connects the first housing and the second housing. The first housing and the second housing are capable of being relatively flattened or folded relative to each other under the action of the folding mechanism. The first screen is fixedly connected to the first housing. The second screen is located on the side of the first housing facing away from the first screen and is fixedly connected to the first housing and the second housing. The first housing has a first mounting space. The first sound-emitting unit and the second sound-emitting unit are both disposed in the first mounting space. The first sound-emitting unit has a first diaphragm, and the second sound-emitting unit has a second diaphragm. Both the first diaphragm and the second diaphragm are disposed facing the first screen or the second screen. The first housing also has a first sound outlet and a second sound outlet spaced apart. The first sound outlet and the second sound outlet both communicate with the first mounting space and the external space of the first housing. The first sound outlet is positioned closer to the first screen than the second screen, and the second sound outlet is positioned closer to the second screen than the first screen. The first sound-emitting unit and the second sound-emitting unit emit sound to the external environment of the electronic device through the first sound outlet and the second sound outlet, respectively.

[0005] Understandably, compared to typical electronic devices that only have an inner or outer earpiece slit, users must maintain the electronic device in a specific state when making calls (e.g., when the electronic device only has an inner earpiece slit, it needs to be in an open state; when it only has an outer earpiece slit, it needs to be in a closed state). This makes the process cumbersome and results in a poor user experience. However, the electronic device in this embodiment can have both an inner earpiece slit (also known as the second audio output in this embodiment) and an outer earpiece slit (also known as the first audio output in this embodiment). Thus, on the one hand, when the electronic device is in an open state, the user does not need to fold the device and can directly use the inner earpiece slit (also known as the second audio output in this embodiment) to make calls. On the other hand, when the electronic device is in a closed state, the user does not need to open the device and can directly use the outer earpiece slit (also known as the first audio output in this embodiment) to make calls. In other words, regardless of whether the electronic device in this embodiment is in an open or closed state, the user can use the corresponding earpiece slit to make calls, resulting in a better user experience.

[0006] Secondly, compared to electronic devices with both inner and outer earpiece slits, which typically feature two sound-emitting units with diaphragms facing opposite directions, allowing one unit's diaphragm to be close to the inner earpiece slit and the other's to be close to the outer earpiece slit, thus enabling better connection between the front cavities of the two units and facilitating sound output. However, when the diaphragms of the two units face opposite directions, their front cavities are spaced apart in the thickness direction, occupying more space in the electronic device and hindering its slim design. In this embodiment, the first diaphragm of the first sound-emitting unit and the second diaphragm of the second sound-emitting unit face the same direction (in this embodiment, both the first and second diaphragms can face either the first or second screen). This allows the front cavities of the first and second sound-emitting units to be located on the same side, enabling them to reuse the thickness space of the electronic device, thereby reducing its thickness and facilitating a slimmer design.

[0007] In one possible implementation, when the first housing and the second housing are folded relative to each other, the first sound unit functions as a receiver. When the first housing and the second housing are unfolded relative to each other, the second sound unit functions as a receiver.

[0008] In this way, when the user uses the electronic device for a call and the device is in a closed state, the first sound unit can act as a receiver. When the electronic device detects that the user's ear is close to the outer screen earpiece slit (i.e., the first sound outlet in this embodiment), the first sound unit can play the call audio content. At this time, the sounds emitted by the first sound unit and the second sound unit can cancel each other out in the far field. Thus, the electronic device in this embodiment can achieve a sound leakage prevention effect when closed. When the user uses the electronic device for a call and the device is in an open state, the second sound unit can act as a receiver. When the electronic device detects that the user's ear is close to the inner screen earpiece slit (i.e., the second sound outlet in this embodiment), the second sound unit can play the call audio content. At this time, the sounds emitted by the first sound unit and the second sound unit can cancel each other out in the far field. Thus, the electronic device in this embodiment can achieve a sound leakage prevention effect when open. That is, the electronic device in this embodiment can achieve a sound leakage prevention effect whether it is in an open or closed state, resulting in a better user experience.

[0009] In one possible implementation, the first sound-emitting unit and the second sound-emitting unit are arranged side by side along the length or width of the first housing.

[0010] Understandably, compared to electronic devices with both inner and outer earpiece slits, the two sound-generating units are typically arranged along the thickness of the electronic device. This allows the diaphragm of one unit to be close to the inner earpiece slit, and the diaphragm of the other to be close to the outer earpiece slit, thus enabling better communication between the front cavities of the two units and facilitating sound output. In other words, the two sound-generating units can be arranged back-to-back. However, arranging the two units back-to-back increases the thickness of the electronic device, hindering its slim design. In this embodiment, the first and second sound-generating units can be arranged side-by-side along the length or width of the first housing. This reduces the thickness of the electronic device, facilitating a slimmer design.

[0011] In one possible implementation, the electronic device has a first space and a second space that are isolated from each other. The first space and the second space are respectively connected to a first sound outlet and a second sound outlet. A first diaphragm is exposed relative to the first space, and a second diaphragm is exposed relative to the second space. The first space and the second space are located on the same side of the first sound-emitting unit and the second sound-emitting unit.

[0012] It is understood that the first space and the second space can be considered as at least parts of the front cavities of the first and second sound-emitting units, respectively. The first sound-emitting unit can use the first space to emit sound to the external environment of the electronic device, and the second sound-emitting unit can use the second space to emit sound to the external environment of the electronic device. In this way, on the one hand, the first space and the second space are isolated from each other, so that the sound emitted by the first sound-emitting unit and the sound emitted by the second sound-emitting unit do not interfere with each other, thereby allowing the sound emitted by the first sound-emitting unit and the sound emitted by the second sound-emitting unit to better cancel each other out in the far field, thus improving the sound leakage prevention effect of the electronic device; on the other hand, the first space and the second space are located on the same side of the first and second sound-emitting units. At this time, the front cavities of the first sound-emitting unit and the second sound-emitting unit can be located on the same side of the first and second sound-emitting units, so that the front cavities of the first sound-emitting unit and the second sound-emitting unit can reuse the thickness space of the electronic device, thereby reducing the thickness of the electronic device and facilitating the thin design of the electronic device.

[0013] In one possible implementation, the first housing further includes a first sound outlet and a second sound outlet, spaced apart from each other. The first sound outlet connects the first sound outlet to the first space. The second sound outlet connects the second sound outlet to the second space. The first and second sound outlets are isolated from each other.

[0014] Understandably, when the first sound-emitting unit is working, it emits sound to the external environment of the electronic device through the first space, the first sound outlet, and the first sound port in sequence. When the second sound-emitting unit is working, it emits sound to the external environment of the electronic device through the second space, the second sound outlet, and the second sound port in sequence. Simultaneously, the first and second sound outlets are isolated from each other. In this way, the sounds emitted by the first and second sound-emitting units do not interfere with each other, allowing the sounds emitted by the first and second sound-emitting units to better cancel each other out in the far field, thereby improving the sound leakage prevention effect of the electronic device.

[0015] In one possible implementation, the first housing includes a middle plate and a frame. The frame is fixedly connected to the periphery of the middle plate, and the frame and the middle plate together enclose a first mounting space. A first screen is located on the side of the middle plate facing the first mounting space and is fixedly connected to the first housing. A second screen is located on the side of the middle plate facing away from the first mounting space and is fixedly connected to the middle plate. A first sound outlet is formed in the frame. The second screen and the first housing enclose a sound-emitting space. The sound-emitting space communicates with a second sound outlet. The first housing also has a connecting hole that connects the sound-emitting space and the second space. The connecting hole and the sound-emitting space together constitute the second sound outlet. In this way, the second sound-emitting unit can emit sound using the space jointly formed by the second space, the connecting hole, and the sound-emitting space. At this time, the space used for sound emission by the second sound-emitting unit is larger, which can reduce the distortion of the sound emitted by the second sound-emitting unit, thereby improving the sound emission effect of the second sound-emitting unit and thus improving the sound emission effect of the electronic device.

[0016] In one possible implementation, the middle plate has a first clearance slot. The opening of the first clearance slot is formed on the surface of the middle plate facing away from the first screen. The first clearance slot connects to a second sound outlet. At least a portion of the second screen covers the first clearance slot, and the first clearance slot constitutes at least a portion of the sound-emitting space. In this way, the second sound-emitting unit can utilize the space of the first clearance slot to emit sound. At this time, the space available for sound emission by the second sound-emitting unit is larger, which can reduce the distortion of the sound emitted by the second sound-emitting unit, thereby improving the sound emission effect of the second sound-emitting unit, and further improving the sound emission effect of the electronic device.

[0017] In one possible implementation, the first housing may further include reinforcing ribs, at least part of which are located within the sound-emitting space. The reinforcing ribs are fixedly connected to the middle plate, or the reinforcing ribs are fixedly connected to the middle plate and the frame, and the reinforcing ribs contact the second screen.

[0018] Understandably, the second screen is a flexible screen, and at least part of it can cover the sound-emitting space. In this case, the portion of the second screen facing the sound-emitting space has relatively low support strength. When the second screen is subjected to external force, this portion is prone to denting and deformation, affecting its flatness. However, the electronic device in this embodiment addresses this by incorporating reinforcing ribs within the sound-emitting space. These ribs contact and support the second screen. This ensures the support strength of the second screen, preventing it from denting under external force and thus contributing to its flatness.

[0019] In one possible implementation, a connecting hole is formed in the middle plate. The connecting hole connects the first clearance slot and the second space. The connecting hole is positioned directly opposite the second diaphragm in the thickness direction of the electronic device.

[0020] In this way, on the one hand, when the second sound-producing unit is working, the second diaphragm can push the air in the second space to pass through the second space, the connecting hole and the first clearance groove in sequence, so as to realize the sound production of the second sound-producing unit; on the other hand, the connecting hole is set directly opposite the second diaphragm in the thickness direction of the electronic device. At this time, the air flows more smoothly when passing through the second space and the connecting hole, thereby improving the sound output effect of the second sound-producing unit and thus improving the sound output effect of the electronic device.

[0021] In one possible implementation, the frame has a second clearance slot. A connecting hole is formed in the frame. The connecting hole connects the second clearance slot and the second space. The first and second clearance slots together constitute a sound-emitting space. In this way, the second sound-emitting unit can utilize the space formed by the second space, the connecting hole, the first clearance slot, and the second clearance slot to emit sound. At this point, the space available for sound emission by the second sound-emitting unit is larger, which can reduce the distortion of the sound emitted by the second sound-emitting unit, thereby improving the sound output effect of the second sound-emitting unit and ultimately improving the sound output effect of the electronic device.

[0022] In one possible implementation, the electronic device further includes a module housing. The module housing is located in a first mounting space. The module housing has an internal space, a first hole, and a second hole. The first hole connects the internal space to a first sound outlet channel. The second hole connects the internal space to a connecting hole. The first hole and the second hole are isolated from each other. A first sound-emitting unit is located in the internal space and, together with the module housing, encloses the first space. The first space connects to the first hole. A second sound-emitting unit is located in the internal space and, together with the module housing, encloses a second space. The second space connects to the second hole.

[0023] Understandably, when the first sound-emitting unit operates, the first diaphragm can push the air within the first space, sequentially passing through the first space, the first hole, the first sound outlet, and the first sound port to emit sound to the external environment of the electronic device. Thus, the first sound-emitting unit can emit sound to the external environment of the electronic device sequentially through the first space, the first hole, the first sound outlet, and the first sound port. When the second sound-emitting unit operates, the second diaphragm can push the air within the second space, sequentially passing through the second space, the second hole, the second sound outlet, and the second sound port to emit sound to the external environment of the electronic device. Thus, the second sound-emitting unit can emit sound to the external environment of the electronic device sequentially through the second space, the second hole, the second sound outlet, and the second sound port.

[0024] Secondly, the first and second holes are isolated from each other. In this way, the sound emitted by the first sound unit and the sound emitted by the second sound unit do not interfere with each other, allowing the sound emitted by the first sound unit and the sound emitted by the second sound unit to cancel each other out better in the far field, thereby improving the sound leakage prevention effect of electronic devices.

[0025] In one possible implementation, the electronic device further includes a first partition. The first partition is located in a first mounting space. The first partition is fixedly connected between the module housing and the first sound-emitting unit. The first sound-emitting unit, together with the module housing and the first partition, encloses the first space. The first sound-emitting unit emits sound to the external environment of the electronic device by sequentially passing through the first space, a first hole, a first sound outlet pipe, and a first sound outlet.

[0026] In this way, the first sound unit, the module housing, and the first partition can cooperate with other components of the electronic device to better isolate the first space from the second space, so that the sound emitted by the first sound unit and the sound emitted by the second sound unit can not interfere with each other, and the sound emitted by the first sound unit and the sound emitted by the second sound unit can better cancel each other in the far field, thereby improving the sound leakage prevention effect of the electronic device.

[0027] In one possible implementation, the electronic device further includes a second partition. The second partition is located in the first mounting space. The second partition is fixedly connected between the module housing and the second sound-emitting unit. The second sound-emitting unit, together with the module housing and the second partition, encloses a second space. The second sound-emitting unit emits sound to the external environment of the electronic device through the second space, a second hole, a second sound outlet duct, and a second sound outlet in sequence.

[0028] In this way, the second sound unit, module housing, and second partition can cooperate with other components of the electronic device to better isolate the first space and the second space, so that the sound emitted by the first sound unit and the sound emitted by the second sound unit can not interfere with each other, and the sound emitted by the first sound unit and the sound emitted by the second sound unit can better cancel each other in the far field, thereby improving the sound leakage prevention effect of the electronic device.

[0029] In one possible implementation, the first sound-emitting unit and the first housing together enclose a first space. The first space is connected to a first sound outlet duct. The second sound-emitting unit and the first housing together enclose a second space. The second space is connected to a second sound outlet duct. The first space and the second space are isolated. In this way, the sound emitted by the first sound-emitting unit and the sound emitted by the second sound-emitting unit can not interfere with each other, thereby allowing the sound emitted by the first sound-emitting unit and the sound emitted by the second sound-emitting unit to better cancel each other out in the far field, thus improving the sound leakage prevention effect of the electronic device.

[0030] In one possible implementation, the electronic device further includes a first partition. The first partition is located in a first mounting space. The first partition is fixedly connected between the first sound-emitting unit and the first housing. The first sound-emitting unit, the first housing, and the first partition together enclose the first space. In this way, the first sound-emitting unit, the first housing, and the first partition can cooperate with other components of the electronic device to better isolate the first space from the second space, thereby preventing interference between the sound emitted by the first sound-emitting unit and the sound emitted by the second sound-emitting unit. This allows the sounds emitted by the first sound-emitting unit and the second sound-emitting unit to better cancel each other out in the far field, thereby improving the sound leakage prevention effect of the electronic device.

[0031] In one possible implementation, the electronic device further includes a third sound-emitting unit. The third sound-emitting unit is located in the first mounting space. The third sound-emitting unit has a third diaphragm. The first diaphragm, the second diaphragm, and the third diaphragm are all positioned facing either the first screen or the second screen. The first housing also has a third sound outlet. The third sound outlet connects the first mounting space with the external space of the first housing. The third sound-emitting unit emits sound to the external environment of the electronic device through the third sound outlet.

[0032] Understandably, compared to typical electronic devices that only include two sound-emitting units, where the two units must emit sounds with opposite phases and equal volume to achieve complete cancellation of sound in the far field and prevent sound leakage, the control of such electronic devices is more difficult, making it difficult to achieve a good sound leakage prevention effect. However, the electronic device in this embodiment can also include a third sound-emitting unit. The third sound-emitting unit provides an additional degree of freedom, improving the control precision of the electronic device when preventing sound leakage. This allows the sounds emitted by the first, second, and third sound-emitting units to cancel each other out in the far field, thereby improving the sound leakage prevention effect, enhancing call privacy, and improving the user experience.

[0033] Secondly, the first, second, and third diaphragms are all positioned facing either the first or second screen. This means that the front cavities of the first, second, and third sound-emitting units are all located on the same side of the same unit. In this configuration, the front cavities of the first, second, and third sound-emitting units can reuse the thickness space of the electronic device, thereby reducing its thickness and facilitating a thinner design.

[0034] In one possible implementation, the first, second, and third sound-emitting units are arranged side-by-side along the length or width of the first housing. This reduces the thickness of the electronic device, facilitating a thinner design.

[0035] In one possible implementation, the electronic device also has a third space. The first space, the second space, and the third space are isolated from each other. The third space is connected to a third sound outlet. The third diaphragm is exposed relative to the third space. The first space, the second space, and the third space are all located on the same side of the first sound unit, the second sound unit, and the third sound unit.

[0036] It is understood that the third space can be considered as at least a portion of the front cavity of the third sound unit. The third sound unit can utilize the third space to emit sound to the external environment of the electronic device. When the third sound unit is operating, it can emit sound to the external environment of the electronic device sequentially through the third space and the third sound outlet. In this way, on the one hand, the first space, the second space, and the third space are isolated from each other, so that the sounds emitted by the first, second, and third sound units do not interfere with each other. This allows the sounds emitted by the first, second, and third sound units to cancel each other out better in the far field, thereby improving the sound leakage prevention effect of the electronic device. On the other hand, the first, second, and third spaces are all located on the same side of the first, second, and third sound units. At this time, the front cavities of the first, second, and third sound units are all located on the same side of the first, second, and third sound units. This allows the front cavities of the first, second, and third sound units to reuse the thickness space of the electronic device, thereby reducing the thickness of the electronic device and facilitating the thin design of the electronic device.

[0037] In one possible implementation, the second housing has a second mounting space and a third sound outlet. The third sound outlet connects the second mounting space and the external space of the second housing. The electronic device also has a third sound-emitting unit. The third sound-emitting unit is located in the second mounting space. The third sound-emitting unit emits sound to the external environment of the electronic device through the third sound outlet.

[0038] Understandably, compared to electronic devices where the first, second, and third sound outlets are all located in the same housing, the manufacturing difficulty and processing cost of the housing are greater. However, in this embodiment, the first and second sound outlets of the electronic device are located in the first housing, and the third sound outlet is located in the second housing. That is, the first, second, and third sound outlets can be formed in two different housings. This reduces the processing difficulty of the electronic device's housing, thereby reducing the processing cost of the electronic device.

[0039] In one possible implementation, the electronic device further includes a controller. The controller is located within a first housing or a second housing. The controller is electrically connected to a first sound-emitting unit, a second sound-emitting unit, and a third sound-emitting unit. The controller inputs a first signal, a second signal, and a third signal to the first sound-emitting unit, the second sound-emitting unit, and the third sound-emitting unit, respectively, to control the first sound-emitting unit, the second sound-emitting unit, and the third sound-emitting unit to emit sound. In this way, the controller can independently control the acoustic signals of the first sound-emitting unit, the second sound-emitting unit, and the third sound-emitting unit, thereby effectively improving the control precision of the electronic device and thus improving the sound leakage prevention effect of the electronic device.

[0083] The embodiments of this application are described below with reference to the accompanying drawings.

[0084] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" refers to at least two.

[0085] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0086] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0089] Figure 1 This is a schematic diagram of the hardware structure of the electronic device 1000 provided in the embodiments of this application.

[0090] like Figure 1As shown, the electronic device 1000 can be a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phone, personal digital assistant (PDA), augmented reality (AR) device, virtual reality (VR) device, artificial intelligence (AI) device, wearable device, in-vehicle device, smart home device and / or smart city device. The embodiments of this application do not impose any special restrictions on the specific type of the electronic device 1000.

[0091] Electronic device 1000 may include processor 110, external memory interface 120, internal memory 121, universal serial bus (USB) interface 130, charging management module 140, power management module 141, battery 142, antenna 1, antenna 2, mobile communication module 150, wireless communication module 160, audio module 170, speaker 170A, receiver 170B, microphone 170C, headphone jack 170D, sensor module 180, button 190, motor 191, indicator 192, camera 193, display screen 200, and subscriber identification module (SIM) card interface 195, etc. The sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, a barometric pressure sensor 180C, a magnetic sensor 180D, an accelerometer sensor 180E, a distance sensor 180F, a proximity sensor 180G, a fingerprint sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, a bone conduction sensor 180M, etc.

[0092] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the electronic device 1000. In other embodiments of this application, the electronic device 1000 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0093] Processor 110 may include one or more processing units, such as an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processing unit (NPU). These different processing units may be independent devices or integrated into one or more processors.

[0094] The controller can generate operation control signals based on the instruction opcode and timing signals to complete the control of instruction fetching and execution.

[0095] The processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. This memory can store instructions or data that the processor 110 has just used or that are used repeatedly. If the processor 110 needs to use the instruction or data again, it can retrieve it directly from the memory. This avoids repeated accesses, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0096] The wireless communication function of the electronic device 1000 can be implemented through antenna 1, antenna 2, mobile communication module 150, wireless communication module 160, modem processor, and baseband processor.

[0097] Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in electronic device 1000 can be used to cover one or more communication frequency bands. Different antennas can also be multiplexed to improve antenna utilization. For example, antenna 1 can be multiplexed as a diversity antenna for a wireless local area network. In some other embodiments, the antennas can be used in conjunction with a tuning switch.

[0098] The mobile communication module 150 can provide solutions for wireless communication, including 2G / 3G / 4G / 5G, applied to the electronic device 1000. The mobile communication module 150 may include at least one filter, switch, power amplifier, low noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves via antenna 1, and perform filtering, amplification, and other processing on the received electromagnetic waves before transmitting them to a modem processor for demodulation. The mobile communication module 150 can also amplify the signal modulated by the modem processor and convert it into electromagnetic waves for radiation via antenna 1. In some embodiments, at least some functional modules of the mobile communication module 150 may be housed in the processor 110. In some embodiments, at least some functional modules of the mobile communication module 150 and at least some modules of the processor 110 may be housed in the same device.

[0099] The modem processor may include a modulator and a demodulator. The modulator modulates the low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs sound signals through audio devices (not limited to speaker 170A, receiver 170B, etc.) or displays images or videos through the display screen 200. In some embodiments, the modem processor may be a separate device. In other embodiments, the modem processor may be independent of the processor 110 and may be housed in the same device as the mobile communication module 150 or other functional modules.

[0100] The wireless communication module 160 can provide solutions for wireless communication applications on the electronic device 1000, 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 infrared (IR) technologies. The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via antenna 2, demodulates and filters the electromagnetic wave signals, and sends the processed signal to processor 110. The wireless communication module 160 can also receive signals to be transmitted from processor 110, frequency modulate and amplify them, and then convert them into electromagnetic waves for radiation via antenna 2.

[0101] In some embodiments, antenna 1 of electronic device 1000 is coupled to mobile communication module 150, and antenna 2 is coupled to wireless communication module 160, enabling electronic device 1000 to communicate with networks and other devices via 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 technologies, etc. The GNSS may include the Global Positioning System (GPS), the Global Navigation Satellite System (GLONASS), the BeiDou Navigation Satellite System (BDS), the Quasi-Zenith Satellite System (QZSS), and / or satellite-based augmentation systems (SBAS).

[0102] Electronic device 1000 implements display functions through a GPU, display screen 200, and application processor. The GPU is a microprocessor for image processing, connected to the display screen 200 and the application processor. The GPU is used to perform mathematical and geometric calculations and for graphics rendering. Processor 110 may include one or more GPUs, which execute program instructions to generate or modify display information.

[0103] The display screen 200 is used to display images, videos, etc. The display screen 200 includes a display panel. In some embodiments, the electronic device 1000 may include one or N display screens 200, where N is a positive integer greater than 1.

[0104] Electronic device 1000 can achieve shooting function through ISP, camera 193, video codec, GPU, display 200 and application processor.

[0105] Camera 193 is used to capture still images or videos. In some embodiments, electronic device 1000 may include one or N cameras 193, where N is a positive integer greater than 1.

[0106] Internal memory 121 may include one or more random access memory (RAM) and one or more non-volatile memory (NVM).

[0107] The random access memory can be directly read and written by the processor 110. It can be used to store executable programs (such as machine instructions) of the operating system or other running programs, as well as user and application data.

[0108] Non-volatile memory can also store executable programs and user and application data, and can be pre-loaded into random access memory for direct reading and writing by the processor 110.

[0109] The external memory interface 120 can be used to connect to external non-volatile memory, thereby expanding the storage capacity of the electronic device 1000. The external non-volatile memory communicates with the processor 110 through the external memory interface 120 to perform data storage functions. For example, music, video, and other files can be stored in the external non-volatile memory.

[0110] Electronic device 1000 can implement audio functions such as music playback and recording through audio module 170, speaker 170A, receiver 170B, microphone 170C, headphone jack 170D, and application processor.

[0111] The audio module 170 is used to convert digital audio information into analog audio signals for output, and also to convert analog audio input into digital audio signals. The audio module 170 can also be used for encoding and decoding audio signals. In some embodiments, the audio module 170 may be located in the processor 110, or some functional modules of the audio module 170 may be located in the processor 110.

[0112] The speaker 170A, also known as a "loudspeaker," is used to convert audio electrical signals into sound signals. Electronic device 1000 can listen to music or make hands-free calls through the speaker 170A.

[0113] In some implementations, the electronic device 1000 can play audio through a speaker 170A.

[0114] The receiver 170B, also known as the "earpiece," is used to convert audio electrical signals into sound signals. When the electronic device 1000 answers a phone call or voice message, the receiver 170B can be brought close to the listener's ear to receive the voice message.

[0115] Microphone 170C, also known as a "microphone" or "voice transducer," is used to convert sound signals into electrical signals. When making a phone call or sending a voice message, the user can speak by bringing their mouth close to microphone 170C, inputting the sound signal into microphone 170C. Electronic device 1000 may have at least one microphone 170C. In some embodiments, electronic device 1000 may have two microphones 170C, which, in addition to collecting sound signals, can also perform noise reduction. In other embodiments, electronic device 1000 may also have three, four, or more microphones 170C, which can collect sound signals, reduce noise, identify the sound source, and perform directional recording, etc.

[0116] The 170D headphone jack is used to connect wired headphones. The 170D headphone jack can be a USB 130 interface or a 3.5mm Open Mobile Terminal Platform (OMTP) standard interface, a CTIA (Cellular Telecommunications Industry Association of the USA) standard interface.

[0117] The gyroscope sensor 180B can be used to determine the motion attitude of the electronic device 1000. In some embodiments, the gyroscope sensor 180B can determine the angular velocity of the electronic device 1000 about three axes (i.e., the x, y, and z axes). The gyroscope sensor 180B can be used for image stabilization. For example, when the shutter is pressed, the gyroscope sensor 180B detects the angle of the electronic device 1000's shake, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to counteract the shake of the electronic device 1000 through reverse movement, thus achieving image stabilization. The gyroscope sensor 180B can also be used in navigation and motion-sensing game scenarios.

[0118] The 180E accelerometer can detect the magnitude of acceleration of electronic device 1000 in various directions (typically three axes). When electronic device 1000 is stationary, it can detect the magnitude and direction of gravity. It can also be used to identify the posture of electronic device 1000, and can be applied to applications such as screen orientation switching and pedometers.

[0119] Touch sensor 180K, also known as a "touch device," can be located on display screen 200. The touch sensor 180K and display screen 200 together form a touchscreen, also known as a "touchscreen." Touch sensor 180K detects touch operations applied to or near it. The touch sensor can transmit the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through display screen 200. In other embodiments, touch sensor 180K may also be located on the surface of electronic device 1000, in a different position than display screen 200.

[0120] Electronic device 1000 can be a portable terminal device running Harmony, iOS, Android, Microsoft, or other operating systems, such as a mobile phone, tablet computer, or wearable device. It can also be a non-portable terminal device such as a laptop computer or desktop computer with a touch-sensitive surface or touch panel. The software system of electronic device 1000 can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. This application embodiment uses a layered Android system as an example to illustrate the software structure of electronic device 1000.

[0121] Figure 2 This is a software structure block diagram of the electronic device 1000 provided in the embodiments of this application.

[0122] A layered architecture divides software into several layers, each with a clear role and function. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom: the application layer, the application framework layer, the Android runtime and system libraries, and the kernel layer.

[0123] The application layer can include a series of application packages.

[0124] like Figure 2 As shown, the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, and SMS.

[0125] The application framework layer provides application programming interfaces (APIs) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

[0126] like Figure 2As shown, the application framework layer may include a window manager, content provider, view system, phone manager, resource manager, notification manager, etc.

[0127] The window manager is used to manage windowed applications. It can retrieve screen size, determine the presence of a status bar, lock the screen, and capture screenshots, among other things.

[0128] Content providers store and retrieve data, making that data accessible to applications. This data may include videos, images, audio, made and received phone calls, browsing history and bookmarks, phone books, etc.

[0129] A view system includes visual controls, such as controls for displaying text and controls for displaying images. View systems can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text notification icon could include views for displaying text and views for displaying images.

[0130] The phone manager is used to provide communication functions for electronic devices 1000. For example, it manages call status (including connection and disconnection).

[0131] The file explorer provides applications with various resources, such as localized strings, icons, images, layout files, video files, and more.

[0132] The notification manager allows applications to display notifications in the status bar. These notifications can be used to deliver informational messages and can disappear automatically after a short pause, requiring no user interaction. For example, the notification manager can be used to notify users of download completion or message alerts. The notification manager can also display notifications as icons or scrolling text in the top status bar, such as notifications from background applications, or as dialog boxes on the screen. Examples include displaying text messages in the status bar, emitting alert sounds, vibrating electronic devices at 1000Hz, and flashing indicator lights.

[0133] The Android Runtime consists of core libraries and a virtual machine. The Android Runtime is responsible for the scheduling and management of the Android system.

[0134] The core library consists of two parts: one part is the functionalities that need to be called by the Java language, and the other part is the Android core library.

[0135] The application layer and application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

[0136] System libraries can include multiple functional modules. For example: surface manager, media libraries, 3D graphics processing libraries (e.g., OpenGLES), 2D graphics engines (e.g., SGL), etc.

[0137] The Surface Manager is used to manage the display subsystem and provides the blending of 2D and 3D layers for multiple applications.

[0138] The media library supports playback and recording of various common audio and video formats, as well as still image files. It supports multiple audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG.

[0139] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0140] A 2D graphics engine is a graphics engine for 2D drawing.

[0141] The kernel layer is the layer between hardware and software. The kernel layer contains at least the display driver, camera driver, audio driver, and sensor driver.

[0142] The following example, using a scene of capturing a photograph, illustrates the workflow of the software and hardware of the electronic device 1000.

[0143] When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into a raw input event (including touch coordinates, timestamp of the touch operation, etc.). The raw input event is stored in the kernel layer. The application framework layer retrieves the raw input event from the kernel layer and identifies the control corresponding to the input event. Taking a touch click as an example, where the corresponding control is the camera application icon, the camera application calls the application framework layer's interface to launch the camera application, and then calls the kernel layer to launch the camera driver, capturing still images or videos through camera 193.

[0144] In some embodiments, the electronic device 1000 may have more than Figure 1 More or fewer components. In some embodiments, the electronic device 1000 may also have more than Figure 2 More or fewer parts.

[0145] Figure 3 This is a schematic diagram of the structure of a typical electronic device 2000 in some embodiments.

[0146] like Figure 3As shown, the electronic device 2000 may include a back cover (not shown) and a display screen, which are positioned opposite to each other, with a frame between them. A speaker (or receiver) outlet is located on one side of the display screen (in the z-direction of the figure). When making a voice call, the user faces one side of the display screen toward their ear, so that the outlet faces their ear. However, this inevitably causes sound leakage, leading to a breach of the user's call privacy. It should be understood that in some embodiments, the electronic device 2000 may be a foldable electronic device, and the display screen may also be located on the side opposite the receiver. For example, a foldable electronic device 2000 includes an inner screen and an outer screen, with the outer screen facing the -z direction and the inner screen facing the z direction. The receiver's outlet may face the inner screen. When the user makes a voice call, the electronic device 2000 needs to be held in a specific state (e.g., an open state) to ensure that the receiver's outlet faces the user's ear, making the operation cumbersome and resulting in a poor user experience.

[0147] To address the aforementioned problems, the embodiments of this application have improved the electronic device 2000.

[0148] The following discussion of electronic devices 1000 will use a foldable mobile phone as an example.

[0149] Figure 4 This is a schematic diagram of one embodiment of the electronic device 1000 provided in this application when it is in a closed state. Figure 5a yes Figure 4 The diagram shows a structural schematic of one embodiment of the electronic device 1000 when it is in the open state. Figure 5b yes Figure 5a This is a structural schematic diagram of the electronic device 1000 from another perspective. It should be noted that... Figures 4 to 5b The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 4 And the accompanying figures below. For ease of description, the width direction of electronic device 1000 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. It is understood that the coordinate system of electronic device 1000 can be flexibly set according to specific actual needs.

[0150] like Figures 4 to 5b As shown, the electronic device 1000 may further include a device housing 300, a speaker module 400, and a folding mechanism 500. The device housing 300 may include a first housing 310 and a second housing 320. The folding mechanism 500 may connect the first housing 310 and the second housing 320. The folding mechanism 500 may deform to allow the first housing 310 and the second housing 320 to be relatively unfolded to an open state or relatively folded to a closed state.

[0151] For example, the display screen 200 may include a first screen 210 and a second screen 220. The second screen 220 may be fixedly connected to the first housing 310 and the second housing 320. The first screen 210 may be located on the side of the first housing 310 facing away from the second screen 220 and is fixedly connected to the first housing 310. The first screen 210 may be a rigid screen. The second screen 220 may be a flexible screen. The second screen 220 may deform. When the electronic device 1000 is in the open state, the first housing 310 and the second housing 320 may be relatively flattened. At this time, the second screen 220 may also be relatively flattened. The second screen 220 is capable of full-screen display, and the electronic device 1000 has a large display area. When the electronic device 1000 is in the closed state, the first housing 310 and the second housing 320 may be relatively folded. At this time, the second screen 220 may be located inside the first housing 310 and the second housing 320. The first screen 210 may be located on the side of the first housing 310 facing away from the second housing 320. The user can operate the first screen 210 to achieve human-computer interaction. In other words, the first screen 210 can be an outer screen, and the second screen 220 can be an inner screen. In some embodiments, the electronic device 1000 may not include either the first screen 210 or the second screen 220.

[0152] Exemplarily, the speaker module 400 can be mounted on the device housing 300. Exemplarily, the speaker module 400 can be mounted on the first housing 310. The first housing 310 may have a sound outlet 311. When the speaker module 400 is operating, the speaker module 400 can play sound to the outside of the electronic device 1000 through the sound outlet 311. The number of sound outlets 311 can be one or more. The number of speaker modules 400 can be one or more.

[0153] For example, the number of sound outlets 311 can be three, such as a first sound outlet 311a, a second sound outlet 311b, and a third sound outlet 311c spaced apart. The first sound outlet 311a can be elongated. The first sound outlet 311a can be located at the top of the first housing 310. The first sound outlet 311a can be positioned closer to the first screen 210 than the second screen 220. The opening of the first sound outlet 311a can be positioned away from the second screen 220. At least a portion of the first sound outlet 311a can be exposed relative to the first screen 210. In this case, the first sound outlet 311a can serve as the earpiece slit of the outer screen of the electronic device 1000. The user can use the first sound outlet 311a as an earpiece for calls when the electronic device 1000 is in a closed state. It should be understood that the top of the first housing 310 can be the side of the first housing 310 facing the sky when the user holds the electronic device 1000 for a call. Unless otherwise specified below, the top of the first housing 310 can be understood in the same way as above.

[0154] For example, the second sound outlet 311b can be elongated. The second sound outlet 311b can be located at the top of the first housing 310. The second sound outlet 311b can be positioned closer to the second screen 220 than the first screen 210. The opening of the second sound outlet 311b can face the top of the first housing 310. In this case, the second sound outlet 311b can serve as an inner screen earpiece slot for the electronic device 1000. The user can use the second sound outlet 311b as an earpiece for calls when the electronic device 1000 is in the open state.

[0155] Exemplarily, the third sound outlet 311c can be a single hole or composed of a plurality of small holes arranged in an array. In this embodiment, the third sound outlet 311c may include three small holes arranged side by side. The third sound outlet 311c may be located at the top of the first housing 310. It should be noted that... Figure 4 The third sound outlet 311c is schematically outlined with dashed lines in the accompanying drawings and subsequent parts.

[0156] In other embodiments, the number of sound outlets 311 may also be different.

[0157] Figure 6 yes Figure 3 The diagram shows an exploded view of the electronic device 1000 in some embodiments. Figure 7 yes Figure 6 The diagram shown is a structural schematic of the first housing 310 in some embodiments. Figure 8 yes Figure 7 The diagram shows the structure of the first housing 310 from another perspective.

[0158] like Figures 6 to 8As shown, the first housing 310 may include a middle plate 312 and a frame 313. The frame 313 may be fixedly connected to the periphery of the middle plate 312, and together with the middle plate 312, enclose a first mounting space 310a of the first housing 310. It should be understood that... Figure 7 This illustration only shows one possible implementation of the first mounting space 310a. In other implementations, the first mounting space 310a may have other dimensions. For example, the length of the first mounting space 310a in the Y-axis direction may be approximately equal to the length of the first housing 310 in the Y-axis direction. The length of the first mounting space 310a in the X-direction may also be approximately equal to the length of the first housing 310 in the X-direction. It should be noted that... Figure 8 In the accompanying drawings and subsequent sections, the middle plate 312 and the frame 313 are schematically divided by dashed lines.

[0159] Exemplarily, the middle plate 312 of the first housing 310 may have a first surface 312a and a second surface 312b disposed opposite to each other along its thickness direction (i.e., the Z-axis direction in this embodiment). The first surface 312a may face the first mounting space 310a. The frame 313 of the first housing 310 may have a first inner surface 313a and a first outer surface 313b disposed opposite to each other. The first inner surface 313a may face the first mounting space 310a. The frame 313 of the first housing 310 may also have a first side surface 313c and a second side surface 313d disposed opposite to each other along the thickness direction of the first housing 310 (i.e., the Z-axis direction in this embodiment). The orientation of the first side surface 313c may be the same as the orientation of the first surface 312a. The orientation of the second side surface 313d may be the same as the orientation of the second surface 312b.

[0160] For example, a first sound outlet 311a may be formed on a first side surface 313c of the frame 313. A second sound outlet 311b may be formed on a first outer side surface 313b of the frame 313. A third sound outlet 311c may be formed on a first outer side surface 313b of the frame 313. In other embodiments, the first sound outlet 311a may also be formed on a first outer side surface 313b of the frame 313. In some other embodiments, the second sound outlet 311b may also be formed on a second side surface 313d of the frame 313.

[0161] Figure 9 yes Figure 5b The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along point AA. Figure 10 yes Figure 5b The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along BB. Figure 11 yes Figure 5bThe diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along CC.

[0162] like Figures 9 to 11 As shown, the first screen 210 can be located on the side of the middle plate 312 of the first housing 310 where the first surface 312a faces away from the second surface 312b, and is fixedly connected to the first housing 310. In this case, the first mounting space 310a can be located between the first screen 210 and the middle plate 312. The first screen 210 can cover the first mounting space 310a. In other embodiments, the first housing 310 may also include a first rear cover. Both the first screen 210 and the first rear cover can be located on the side of the middle plate 312 where the first surface 312a faces away from the second surface 312b. The first screen 210 and / or the first rear cover can cover the first mounting space 310a.

[0163] For example, a portion of the second screen 220 may be located on the side of the second surface 312b of the middle plate 312 facing away from the first surface 312a, and fixedly connected to the first housing 310. For example, the second screen 220 may be fixedly connected to the second surface 312b of the middle plate 312. In this case, the middle plate 312 can be used to support the second screen 220. Thus, the middle plate 312 can provide a relatively flat supporting environment for the second screen 220, thereby ensuring the flatness of the second screen 220.

[0164] For example, the first housing 310 may also have a sound outlet 314. The sound outlet 314 may connect the sound outlet 311 and the first mounting space 310a. In this case, the first mounting space 310a may be connected to the external space of the first housing 310 in sequence through the sound outlet 314 and the sound outlet 311.

[0165] For example, the number of sound outlet pipes 314 can be three, such as a first sound outlet pipe 314a, a second sound outlet pipe 314b, and a third sound outlet pipe 314c. The first sound outlet pipe 314a, the second sound outlet pipe 314b, and the third sound outlet pipe 314c can be connected one-to-one to the first sound outlet 311a, the second sound outlet 311b, and the third sound outlet 311c. Both the first sound outlet pipe 314a and the third sound outlet pipe 314c can be formed on the frame 313 of the first housing 310. The first sound outlet pipe 314a can be spaced apart from the third sound outlet pipe 314c. For example, one end of the first sound outlet pipe 314a can be connected to the first sound outlet 311a, and the other end can penetrate the first inner side surface 313a of the frame 313 to connect to the first mounting space 310a. One end of the third sound outlet duct 314c can be connected to the third sound outlet 311c, and the other end can pass through the first inner side surface 313a of the frame 313 to connect to the first mounting space 310a. In other embodiments, the number of sound outlet ducts 314 can also be other.

[0166] For example, please combine Figure 8 As shown, the middle plate 312 of the first housing 310 may also have a first clearance groove 312c. The frame 313 of the first housing 310 may also have a second clearance groove 313e. The first clearance groove 312c may connect to the second clearance groove 313e. The opening of the first clearance groove 312c may be formed on the second surface 312b of the middle plate 312. The second clearance groove 313e may connect to the second sound outlet 311b. At this time, the first clearance groove 312c and the second clearance groove 313e may together constitute a sound-emitting space 317. The second screen 220 may cover the sound-emitting space 317.

[0167] For example, the middle plate 312 of the first housing 310 may also have a connecting hole 315. The connecting hole 315 can penetrate through the first surface 312a and the second surface 312b of the middle plate 312. The connecting hole 315 can connect the first clearance groove 312c and the first mounting space 310a. The second clearance groove 313e can connect to the first mounting space 310a in sequence through the first clearance groove 312c and the connecting hole 315. That is, the sound-emitting space 317 can connect to the first mounting space 310a through the connecting hole 315. At this time, the second sound outlet 311b can connect to the first mounting space 310a in sequence through the sound-emitting space 317 and the connecting hole 315. The sound-emitting space 317 and the connecting hole 315 can together form the second sound outlet duct 314b. That is, the second sound outlet 311b can connect to the first mounting space 310a through the second sound outlet duct 314b. In other embodiments, the frame 313 may not have the second clearance groove 313e, that is, the sound-emitting space 317 may be formed only by the first clearance groove 312c. In this case, the opening of the second sound outlet 311b may face away from the first screen 210.

[0168] For example, the first housing 310 may also have reinforcing ribs 316. Figure 8The structure of the reinforcing rib 316 is also illustrated in the diagram. At least a portion of the reinforcing rib 316 can be located within the sound-emitting space 317. The reinforcing rib 316 can be fixedly connected to the middle plate 312, or fixedly connected to the middle plate 312 and the frame 313. It is understood that the second screen 220 is a flexible screen, and at least a portion of the second screen 220 can cover the sound-emitting space 317. At this time, the support strength of the portion of the second screen 220 facing the sound-emitting space 317 is relatively low. When the second screen 220 is subjected to external force, the portion of the second screen 220 facing the sound-emitting space 317 is prone to denting and deformation under the action of external force, which will affect the flatness of the second screen 220. However, the electronic device 1000 in this embodiment provides a reinforcing rib 316 within the sound-emitting space 317. The reinforcing rib 316 can support the second screen 220, thereby ensuring the support strength of the second screen 220, preventing the second screen 220 from denting under the action of external force, and helping to ensure the flatness of the second screen 220.

[0169] Figure 12a yes Figure 6 The diagram shows a partial assembly structure of the first housing 310 and the first connector 610 in one embodiment. Figure 12b yes Figure 6 The diagram shows a partial assembly structure of the first housing 310 and the second connector 620 in one embodiment.

[0170] like Figure 12a and Figure 12b As shown, the electronic device 1000 may further include a first connector 610 and a second connector 620. Figure 6 The structure of the first connector 610 and the second connector 620 is also illustrated in the diagram. Both the first connector 610 and the second connector 620 can be adhesives. It should be noted that... Figure 12a and Figure 12b The diagram only illustrates the shape of the first connector 610 and the second connector 620 in one embodiment. In other embodiments, the shapes of the first connector 610 and the second connector 620 may be different. This application does not specifically limit the shapes in this regard.

[0171] Exemplarily, the first connector 610 may be located on the side of the first housing 310 facing the first screen 210. The first connector 610 may be fixedly connected between the first screen 210 and the first housing 310. The first connector 610 may be disposed around the first mounting space 310a. The first screen 210 may be fixedly connected to the first housing 310 via the first connector 610 (see also...). Figure 10(As shown). In this way, on the one hand, the first connector 610 can be used to assemble the first screen 210 and the first housing 310; on the other hand, the first connector 610 can also cooperate with the first screen 210 and the first housing 310 to better seal the first mounting space 310a.

[0172] Exemplarily, the second connector 620 may be located on the side of the first housing 310 facing the second screen 220. The second connector 620 may be fixedly connected between the first housing 310 and the second screen 220. The second connector 620 may be positioned around the sound-emitting space 317. A portion of the second screen 220 may be fixedly connected to the first housing 310 via the second connector 620 (see reference). Figure 10 (As shown). In this way, on the one hand, the second connector 620 can be used to assemble the second screen 220 with the first housing 310; on the other hand, the second connector 620 can also cooperate with the second screen 220 and the first housing 310 to better seal the sound-emitting space 317.

[0173] In some embodiments, the first surface 312a of the middle plate 312 of the first housing 310 can be partially recessed to form a clearance step. The first connector 610 can be located within the clearance step. This reduces the space occupied by the first connector 610, which is beneficial for achieving a thinner design of the electronic device 1000.

[0174] In some embodiments, the second surface 312b of the middle plate 312 of the first housing 310 may also be partially recessed to form a clearance step. The second connector 620 may be located within the clearance step. This reduces the space occupied by the second connector 620, which is beneficial for achieving a thinner design of the electronic device 1000.

[0175] Figure 13 yes Figure 6 The speaker module 400 shown is a structural schematic diagram in some embodiments. Figure 14 yes Figure 13 The speaker module 400 shown is an exploded structural diagram in some embodiments. Figure 15 yes Figure 14 The speaker module 400 shown is partially illustrated from another perspective.

[0176] like Figures 13 to 15 As shown, the speaker module 400 may include a module housing 10 and a sound-emitting structure 20. The sound-emitting structure 20 may be mounted on the module housing 10. The module housing 10 may include an upper shell 11 and a base plate 12. In other embodiments, the module housing 10 may also be a one-piece molded structure, that is, the upper shell 11 and the base plate 12 may be integrally molded.

[0177] Exemplarily, the upper shell 11 may include a top 111 and a frame portion 112. The frame portion 112 may be fixedly connected to the periphery of the top 111. Exemplarily, the upper shell 11 may have a first hole 11a, a second hole 11b, and a third hole 11c spaced apart. Exemplarily, both the first hole 11a and the third hole 11c may be located on the frame portion 112 of the upper shell 11. Both the first hole 11a and the third hole 11c may penetrate the inner and outer peripheral sides of the frame portion 112. The first hole 11a and the third hole 11c may be located on the same side of the frame portion 112. The first hole 11a and the third hole 11c may be arranged side by side along the width direction of the speaker module 400 (i.e., the X-axis direction in this embodiment). In other embodiments, the first hole 11a and the third hole 11c may also be located on different sides of the frame portion 112. The position and arrangement of the first hole 11a and the third hole 11c may also be in other forms.

[0178] For example, the second hole 11b may be located at the top 111 of the upper shell 11. The second hole 11b may penetrate two surfaces of the top 111 along its thickness direction (i.e., the Z-axis direction in this embodiment).

[0179] Figure 16 yes Figure 13 The diagram shows a partial cross-sectional view of one embodiment of the speaker module 400 cut along DD.

[0180] like Figures 14 to 16 As shown, the base plate 12 can be located on the side of the frame portion 112 of the upper shell 11 facing away from the top 111, and is fixedly connected to the frame portion 112. At this time, the base plate 12 and the upper shell 11 can enclose the internal space 10a of the module housing 10. The first hole 11a, the second hole 11b, and the third hole 11c of the upper shell 11 can all communicate with the internal space 10a of the module housing 10.

[0181] For example, the base plate 12 may have a first clearance hole 12a and a second clearance hole 12b spaced apart. Both the first clearance hole 12a and the second clearance hole 12b can connect the internal space 10a of the speaker module 400 with the external space.

[0182] Figure 17 yes Figure 13 The diagram shows a cross-sectional view of one embodiment of the speaker module 400 cut along DD.

[0183] like Figure 17As shown, the sound-emitting structure 20 can be located within the internal space 10a of the module housing 10 and can be fixedly connected to the module housing 10. The sound-emitting structure 20 may include a first sound-emitting unit 21, a second sound-emitting unit 22, and a third sound-emitting unit 23. Exemplarily, the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23 can be arranged side by side along the width direction (i.e., the X-axis direction in this embodiment) of the speaker module 400. The second sound-emitting unit 22 can be located between the first sound-emitting unit 21 and the third sound-emitting unit 23. In other embodiments, the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23 can also be arranged side by side along the length direction (i.e., the Y-axis direction in this embodiment) of the speaker module 400. In some other embodiments, the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23 can also be arranged alternately. It should be understood that the side-by-side arrangement of the first sound unit 21, the second sound unit 22, and the third sound unit 23 can mean that the first sound unit 21, the second sound unit 22, and the third sound unit 23 are arranged on the plane containing the width and length directions of the speaker module 400 (in this embodiment, that is, the plane containing the X-axis and Y-axis directions). Unless otherwise specified below, the side-by-side arrangement can be understood in the same way as above.

[0184] Exemplarily, the first sound-generating unit 21 may include a first diaphragm 21a. The second sound-generating unit 22 may include a second diaphragm 22a. The third sound-generating unit 23 may include a third diaphragm 23a. The first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a may all face the top 111 of the upper shell 11. That is, the orientations of the first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a may be the same. It should be noted that the orientation of the first diaphragm 21a may be the direction in which the first diaphragm 21a faces away from other components (such as magnetic circuit components) of the first sound-generating unit 21. The orientation of the second diaphragm 22a may be the direction in which the second diaphragm 22a faces away from other components (such as magnetic circuit components) of the second sound-generating unit 22. The orientation of the third diaphragm 23a may be the direction in which the third diaphragm 23a faces away from other components (such as magnetic circuit components) of the third sound-generating unit 23. Unless otherwise specified below, the orientations of the first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a can be understood in accordance with the above.

[0185] For example, the first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a can be integrally molded structures. It should be noted that... Figure 14 The first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a are schematically divided by dashed lines.

[0186] In other embodiments, the first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a may also be independent diaphragms.

[0187] Figure 18 yes Figure 13 The diagram shows a cross-sectional view of one embodiment of the speaker module 400 cut along EE.

[0188] like Figure 17 and Figure 18 As shown, the speaker module 400 may further include a first partition 113a. The first partition 113a may be located in the internal space 10a and fixedly connected to the top 111 of the upper shell 11. The first sound-emitting unit 21 may be located on the side of the first partition 113a facing away from the top 111 and fixedly connected to the first partition 113a. In this case, the first sound-emitting unit 21 may be spaced apart from the top 111 of the upper shell 11. The first sound-emitting unit 21, together with the top 111 of the upper shell 11, the frame portion 112, and the first partition 113a, can jointly enclose the first space 30a. That is, the first sound-emitting unit 21, together with the upper shell 11 and the first partition 113a, can jointly enclose the first space 30a.

[0189] For example, the first hole 11a can connect to the first space 30a. The first space 30a can connect to the external space of the speaker module 400 through the first hole 11a. At least a portion of the first diaphragm 21a can be exposed relative to the first space 30a. When the speaker module 400 is operating, the first diaphragm 21a of the first sound-emitting unit 21 can push the air within the first space 30a, passing sequentially through the first space 30a and the first hole 11a, to emit sound into the external space of the speaker module 400. At this time, the first space 30a can be considered as at least a portion of the front cavity of the first sound-emitting unit 21.

[0190] Exemplarily, the first diaphragm 21a of the first sound-generating unit 21 can, together with other components of the first sound-generating unit 21, enclose the inner cavity of the first sound-generating unit 21 (not shown). The inner cavity of the first sound-generating unit 21 and the first space 30a can be located on opposite sides of the first diaphragm 21a. The first diaphragm 21a can be used to isolate the inner cavity of the first sound-generating unit 21 from the first space 30a. The inner cavity of the first sound-generating unit 21 can be considered as at least a portion of the rear cavity of the first sound-generating unit 21. In this way, the inner cavity of the first sound-generating unit 21 can be isolated from the first space 30a, thereby preventing acoustic short circuits in the first sound-generating unit 21 and affecting its acoustic performance.

[0191] For example, at least a portion of the first sound-emitting unit 21 may be exposed relative to the first clearance hole 12a. In this case, the inner cavity of the first sound-emitting unit 21 can be connected to the external space of the speaker module 400 through the first clearance hole 12a. The first sound-emitting unit 21 can be regarded as a sound-emitting unit that matches the open cavity.

[0192] Figure 19 yes Figure 13 The diagram shows a cross-sectional view of one embodiment of the speaker module 400 cut along FF.

[0193] like Figure 17 and Figure 19 As shown, the speaker module 400 may further include a second partition 113b. The second partition 113b may be located in the internal space 10a and fixedly connected to the top 111 of the upper shell 11. The second sound-emitting unit 22 may be located on the side of the second partition 113b facing away from the top 111 and fixedly connected to the second partition 113b. In this case, the second sound-emitting unit 22 may be spaced apart from the top 111 of the upper shell 11. The second sound-emitting unit 22, together with the top 111 of the upper shell 11 and the second partition 113b, may enclose a second space 30b.

[0194] For example, the second hole 11b can connect to the second space 30b. The second space 30b can connect to the external space of the speaker module 400 through the second hole 11b. At least a portion of the second diaphragm 22a can be exposed relative to the second space 30b. When the speaker module 400 is operating, the second diaphragm 22a of the second sound-emitting unit 22 can push the air within the second space 30b, passing sequentially through the second space 30b and the second hole 11b, to emit sound into the external space of the speaker module 400. At this time, the second space 30b can be considered at least a portion of the front cavity of the second sound-emitting unit 22.

[0195] Exemplarily, the second diaphragm 22a of the second sound-emitting unit 22 can, together with other components of the second sound-emitting unit 22, enclose the inner cavity of the second sound-emitting unit 22 (not shown). The inner cavity of the second sound-emitting unit 22 and the second space 30b can be located on opposite sides of the second diaphragm 22a. The second diaphragm 22a can be used to isolate the inner cavity of the second sound-emitting unit 22 from the second space 30b. The inner cavity of the second sound-emitting unit 22 can be considered as at least a portion of the rear cavity of the second sound-emitting unit 22. In this way, the inner cavity of the second sound-emitting unit 22 can be isolated from the second space 30b, thereby preventing acoustic short circuits in the second sound-emitting unit 22 and affecting its acoustic performance.

[0196] For example, at least a portion of the second sound-emitting unit 22 may be exposed relative to the first clearance hole 12a. In this case, the inner cavity of the second sound-emitting unit 22 can communicate with the external space of the speaker module 400 through the first clearance hole 12a. The second sound-emitting unit 22 can be regarded as a sound-emitting unit that matches the open cavity.

[0197] Figure 20 yes Figure 13 The diagram shows a cross-sectional view of one embodiment of the speaker module 400 cut along line GG.

[0198] like Figure 17 and Figure 20 As shown, the speaker module 400 may further include a third partition 113c. The third partition 113c may be located in the internal space 10a and fixedly connected to the top 111 of the upper shell 11. The third sound-emitting unit 23 may be located on the side of the third partition 113c facing away from the top 111 and fixedly connected to the third partition 113c. In this case, the third sound-emitting unit 23 may be spaced apart from the top 111 of the upper shell 11. The third sound-emitting unit 23, together with the top 111 of the upper shell 11 and the third partition 113c, may together enclose a third space 30c.

[0199] For example, the third hole 11c can connect to the third space 30c. The third space 30c can connect to the external space of the speaker module 400 through the third hole 11c. At least a portion of the third diaphragm 23a can be exposed relative to the third space 30c. When the speaker module 400 is operating, the third diaphragm 23a of the third sound-emitting unit 23 can push the air within the third space 30c, passing sequentially through the third space 30c and the third hole 11c, to emit sound into the external space of the speaker module 400. At this time, the third space 30c can be considered as at least a portion of the front cavity of the third sound-emitting unit 23.

[0200] Exemplarily, the third sound-emitting unit 23 can also be fixedly connected to the base plate 12 of the module housing 10. At least a portion of the third sound-emitting unit 23 can be exposed relative to the second clearance hole 12b, and can also cover the second clearance hole 12b. The third diaphragm 23a of the third sound-emitting unit 23 can, together with other components of the third sound-emitting unit 23, enclose the inner cavity of the third sound-emitting unit 23 (not shown). The inner cavity of the third sound-emitting unit 23 and the third space 30c can be located on opposite sides of the third diaphragm 23a. The third diaphragm 23a can be used to isolate the inner cavity of the third sound-emitting unit 23 from the third space 30c. The inner cavity of the third sound-emitting unit 23 can be considered as at least a portion of the rear cavity of the third sound-emitting unit 23. In this way, the inner cavity of the third sound-emitting unit 23 can be isolated from the third space 30c, thereby preventing acoustic short circuits in the third sound-emitting unit 23 and affecting its acoustic performance.

[0201] For example, the inner cavity of the third sound-emitting unit 23 can be connected to the internal space 10a of the speaker module 400 through the second clearance hole 12b, and is isolated from the external space of the speaker module 400. In this case, the third sound-emitting unit 23 can be regarded as a sound-emitting unit that matches the closed cavity. In some embodiments, a portion of the third sound-emitting unit 23 can be embedded in the second clearance hole 12b. In this way, the second clearance hole 12b can be used to cooperate with the third sound-emitting unit 23 during the assembly of the base plate 12 to achieve assembly positioning.

[0202] For example, the first partition 113a, the second partition 113b, and the third partition 113c can be arranged side by side along the width direction of the speaker module 400 (see reference). Figure 15 (As shown). The second partition 113b can be located between the first partition 113a and the third partition 113c. Exemplarily, the first partition 113a, the second partition 113b, and the third partition 113c can be an integrally formed structure. It should be noted that... Figure 15 In the accompanying drawings and subsequent sections, the first partition 113a, the second partition 113b, and the third partition 113c are schematically divided by dashed lines. In other embodiments, the first partition 113a, the second partition 113b, and the third partition 113c may also be independent structural components.

[0203] Exemplarily, the upper shell 11 can also be a one-piece molded structure, that is, the top 111 and the frame portion 112 can be integrally molded. Exemplarily, the top 111, the frame portion 112, the first partition 113a, the second partition 113b, and the third partition 113c of the upper shell 11 can also be integrally molded. In other embodiments, one or more of the top 111, the frame portion 112, the first partition 113a, the second partition 113b, and the third partition 113c of the upper shell 11 can also be independent structural components.

[0204] For example, the sound-emitting structure 20 can cooperate with the module housing 10, the first partition 113a, the second partition 113b, and the third partition 113c of the speaker module 400 (see reference). Figure 17 (as shown), so that the first space 30a, the second space 30b and the third space 30c are isolated from each other.

[0205] Figure 21a yes Figure 5b A partial cross-sectional structural diagram of one embodiment of the electronic device 1000 cut along HH. Figure 21b yes Figure 5b The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along point AA. Figure 22a yes Figure 5b A partial structural schematic diagram of the electronic device 1000 shown. Figure 22b yes Figure 5b A partial structural schematic diagram of the electronic device 1000 shown from another perspective.

[0206] like Figures 21a to 22bAs shown, the speaker module 400 can be located in the first mounting space 310a of the first housing 310 and can be fixedly connected to the first housing 310. The top 111 of the upper shell 11 of the speaker module 400 can be fixedly connected to the first surface 312a of the middle plate 312 of the first housing 310. The frame portion 112 of the upper shell 11 of the speaker module 400 can be fixedly connected to the first inner surface 313a of the side frame 313 of the first housing 310. In this case, the first mounting space 310a of the first housing 310 can constitute the external space of the speaker module 400. The module housing 10 of the speaker module 400 can cooperate with the first housing 310 to isolate the first sound outlet duct 314a, the second sound outlet duct 314b, and the third sound outlet duct 314c from each other.

[0207] For example, the first surface 312a of the middle plate 312 of the first housing 310 can be partially recessed to form a first clearance space 318. Figure 7 The structure of the first clearance space 318 is also illustrated in the diagram. The speaker module 400 can be located within the first clearance space 318. This reduces the space occupied by the speaker module 400, which is beneficial for achieving a thinner and lighter electronic device 1000.

[0208] Figure 23 yes Figure 5b The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along BB.

[0209] like Figure 21a and Figure 23 As shown, the first hole 11a can be positioned directly opposite the first sound outlet duct 314a. The first hole 11a can connect to the first sound outlet duct 314a. The first sound outlet duct 314a can connect to the first space 30a through the first hole 11a. At this time, the first sound outlet 311a can connect to the first space 30a through the first sound outlet duct 314a and the first hole 11a. When the speaker module 400 is working, the first diaphragm 21a can push the air in the first space 30a, passing through the first space 30a, the first hole 11a, the first sound outlet duct 314a, and the first sound outlet 311a in sequence, to emit sound to the external environment of the electronic device 1000. That is, the first sound-emitting unit 21 can emit sound to the external environment of the electronic device 1000 in sequence through the first space 30a, the first hole 11a, the first sound outlet duct 314a, and the first sound outlet 311a. At this time, the first space 30a, the first hole 11a and the first sound outlet duct 314a can together form the front cavity of the first sound-producing unit 21.

[0210] Figure 24 yes Figure 5b A partial cross-sectional structural diagram of one embodiment of the electronic device 1000 cut along point II.

[0211] like Figure 21a and Figure 24 As shown, the second hole 11b can be positioned directly opposite the connecting hole 315. The second hole 11b can connect to the connecting hole 315. That is, the second sound outlet 314b can connect to the second hole 11b, and thus connect to the second space 30b. At this time, the second sound outlet 311b can connect to the second space 30b through the second sound outlet 314b and the second hole 11b. When the speaker module 400 is working, the second diaphragm 22a can push the air in the second space 30b, passing through the second space 30b, the second hole 11b, the second sound outlet 314b, and the second sound outlet 311b in sequence, to emit sound to the external environment of the electronic device 1000. That is, the second sound-emitting unit 22 can emit sound to the external environment of the electronic device 1000 in sequence through the second space 30b, the second hole 11b, the second sound outlet 314b, and the second sound outlet 311b. At this time, the second space 30b, the second hole 11b and the second sound outlet duct 314b can together form the front cavity of the second sound unit 22.

[0212] Figure 25 yes Figure 5b The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along JJ.

[0213] like Figure 25 As shown, the third hole 11c can be positioned directly opposite the third sound outlet duct 314c. The third hole 11c can connect to the third sound outlet duct 314c. The third sound outlet duct 314c can connect to the third space 30c through the third hole 11c. At this time, the third sound outlet 311c can connect to the third space 30c through the third sound outlet duct 314c and the third hole 11c. When the speaker module 400 is working, the third diaphragm 23a can push the air in the third space 30c, passing through the third space 30c, the third hole 11c, the third sound outlet duct 314c, and the third sound outlet 311c in sequence, to emit sound to the external environment of the electronic device 1000. That is, the third sound-emitting unit 23 can emit sound to the external environment of the electronic device 1000 in sequence through the third space 30c, the third hole 11c, the third sound outlet duct 314c, and the third sound outlet 311c. At this time, the third space 30c, the third hole 11c and the third sound outlet duct 314c can together form the front cavity of the third sound unit 23.

[0214] For example, when the electronic device 1000 is in a closed state (please refer to...) Figure 4As shown, the user can interact with the first screen 210. The first sound outlet 311a can serve as an external screen earpiece slit. When the user makes a call using the electronic device 1000, the first sound unit 21 can act as a receiver. The first sound unit 21 can play the call audio content. The sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 can cancel each other out in the far field, thereby achieving a sound leakage prevention effect when the electronic device 1000 is in a closed state.

[0215] For example, when the electronic device 1000 is in the on state (please refer to...) Figure 5a As shown, the user can interact with the second screen 220. The second sound outlet 311b can serve as an inner screen earpiece. When the user makes a call using the electronic device 1000, the second sound unit 22 can act as a receiver. The second sound unit 22 can play the call audio content. The sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 can cancel each other out in the far field, thus achieving a sound leakage prevention effect when the electronic device 1000 is turned on.

[0216] Understandably, compared to typical electronic devices that only have an inner or outer earpiece slit, users need to keep the electronic device in a specific state when making a call (for example, when the electronic device only has an inner earpiece slit, it needs to be in an open state; when the electronic device only has an outer earpiece slit, it needs to be in a closed state). This makes the process of making a call cumbersome and results in a poor user experience. However, the electronic device 1000 in this embodiment can simultaneously have an inner earpiece slit (also known as the second sound outlet 311b in this embodiment) and an outer earpiece slit (also known as the first sound outlet 311a in this embodiment). Thus, when the electronic device 1000 is in an open state, the user does not need to fold the electronic device 1000 but can directly use the inner earpiece slit (also known as the second sound outlet 311b in this embodiment) to make a call. When the electronic device 1000 detects that the user's ear is close to the inner earpiece slit (also known as the second sound outlet 311b in this embodiment), the second sound unit 22 can play the call audio content. At this time, the sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 can cancel each other out in the far field. Thus, the electronic device 1000 in this embodiment can achieve a sound leakage prevention effect when open. On the other hand, when the electronic device 1000 is in a closed state, the user does not need to open the electronic device 1000, but can directly use the outer screen earpiece slit (i.e., the first sound outlet 311a in this embodiment) to make a call. When the electronic device 1000 detects that the user's ear is close to the outer screen earpiece slit (i.e., the first sound outlet 311a in this embodiment), the first sound unit 21 plays the call audio content. At this time, the sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 can cancel each other out in the far field. Thus, the electronic device 1000 in this embodiment can achieve a sound leakage prevention effect when closed. That is, regardless of whether the electronic device 1000 in this embodiment is in an open or closed state, the user can use the corresponding earpiece slit to make a call, resulting in a better user experience.

[0217] Secondly, compared to electronic devices that have both inner and outer earpiece slits, the two speaker units are typically arranged along the thickness of the electronic device, with their diaphragms facing opposite directions. This allows one speaker diaphragm to be closer to the inner earpiece slit and the other closer to the outer earpiece slit, ensuring better connection between the front cavities of the two units and facilitating sound output. In other words, the two speaker units can be arranged back-to-back. However, arranging the two speaker units back-to-back increases the thickness of the speaker module, and consequently, the thickness of the electronic device. Furthermore, the opposite diaphragm orientation and the spaced-apart front cavities of the two units along the Z-axis occupy more space, hindering the design of a thinner and lighter electronic device. In this embodiment, the first sound-emitting unit 21 of the electronic device 1000 can be arranged side by side with the second sound-emitting unit 22, and the first diaphragm 21a of the first sound-emitting unit 21 and the second diaphragm 22a of the second sound-emitting unit 22 have the same orientation (in this embodiment, both the first diaphragm 21a and the second diaphragm 22a can face the top 111 of the upper shell 11 of the speaker module 400). In this way, on the one hand, the first sound-emitting unit 21 and the second sound-emitting unit 22 are arranged side by side, which can reduce the overall thickness of the speaker module 400, thereby reducing the thickness of the electronic device 1000, which is conducive to realizing the thin design of the electronic device 1000; on the other hand, the first diaphragm 21a of the first sound-emitting unit 21 and the second diaphragm 22a of the second sound-emitting unit 22 are oriented in the same direction, so that the front cavity of the first sound-emitting unit 21 and the front cavity of the second sound-emitting unit 22 can be located on the same side of the first sound-emitting unit 21 and the second sound-emitting unit 22, thereby allowing the front cavity of the first sound-emitting unit 21 and the front cavity of the second sound-emitting unit 22 to reuse the thickness space of the electronic device 1000, thereby further reducing the thickness of the electronic device 1000, which is conducive to realizing the thin design of the electronic device 1000.

[0218] Furthermore, compared to conventional electronic devices that only include two sound-emitting units, where the two units must emit sounds with opposite phases and equal volume to achieve complete cancellation of sound in the far field and thus prevent sound leakage, electronic devices are more difficult to control and cannot achieve a good sound leakage prevention effect. The electronic device 1000 in this embodiment can also include a third sound-emitting unit 23. The third sound-emitting unit 23 provides an additional degree of freedom, improving the control precision of the electronic device 1000 when preventing sound leakage. This allows the sounds emitted by the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23 to cancel each other out in the far field, thereby improving the sound leakage prevention effect of the electronic device 1000, enhancing the privacy of calls, and improving the user experience.

[0219] Furthermore, unlike typical electronic devices that include four sound-emitting units, where the sounds emitted by these four units cancel each other out to prevent sound leakage, the electronic device in this embodiment only includes a first sound-emitting unit 21, a second sound-emitting unit 22, and a third sound-emitting unit 23. This allows the sounds emitted by the first, second, and third sound-emitting units 21, 22, and 23 to cancel each other out in the far field, thus preventing sound leakage and meeting user requirements. Additionally, the cancellation of these sounds in the user's ear is weaker, ensuring sufficient volume during calls and improving the user experience.

[0220] Furthermore, the first housing 310 of the electronic device 1000 in this embodiment has a connecting hole 315, which can connect to the second hole 11b. The second space 30b can connect to the connecting hole 315 through the second hole 11b. At this time, the second space 30b can connect to the sound-emitting space 317 through the second hole 11b and the connecting hole 315, that is, the second space 30b can connect to the second sound outlet duct 314b through the second hole 11b. When the speaker module 400 is working, the second sound-emitting unit 22 can emit sound using the space jointly formed by the second space 30b, the second hole 11b, and the second sound outlet duct 314b. In this way, the space used for sound emission by the second sound-emitting unit 22 is larger, which can reduce the distortion of the sound emitted by the second sound-emitting unit 22, thereby improving the sound emission effect of the second sound-emitting unit 22, and thus improving the sound emission effect of the electronic device 1000.

[0221] Furthermore, in this embodiment, the first space 30a, the second space 30b, and the third space 30c of the electronic device 1000 are mutually isolated, ensuring that the sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 do not interfere with each other. This allows the sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 to better cancel each other out in the far field, thereby improving the sound leakage prevention performance of the electronic device 1000.

[0222] Furthermore, in this embodiment, the first sound outlet duct 314a, the second sound outlet duct 314b, and the third sound outlet duct 314c of the electronic device 1000 are isolated from each other. This ensures that the sounds emitted by the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23 do not interfere with each other, allowing the sounds emitted by these three units to better cancel each other out in the far field, thereby improving the sound leakage prevention performance of the electronic device 1000.

[0223] In addition, please combine Figure 26 As shown, Figure 26 yes Figure 4 The diagram shows a simplified representation of the electronic device 1000 in some embodiments. In this embodiment, the first sound outlet 311a is positioned closer to the first screen 210 than the second screen 220, the second sound outlet 311b is positioned closer to the second screen 220 than the first screen 210, and the third sound outlet 311c is located at the top of the first housing 310. Thus, compared to electronic devices with multiple sound outlets in the same position, the sound emitted by the speaker module has a single direction, making it easily blocked and affecting the external playback effect. In this embodiment, the different positions of the first sound outlet 311a, the second sound outlet 311b, and the third sound outlet 311c of the electronic device 1000 ensure that the sound emitted by the speaker module 400 through the first sound outlet 311a, the second sound outlet 311b, and the third sound outlet 311c has multiple degrees of freedom in direction, guaranteeing the external playback performance of the speaker module 400 and improving the stability of the sound leakage prevention effect of the electronic device 1000.

[0224] In some embodiments, the electronic device 1000 may further include a controller, a first power amplifier, a second power amplifier, and a third power amplifier. The controller, the first power amplifier, the second power amplifier, and the third power amplifier may all be located in the first mounting space 310a. The first power amplifier, the second power amplifier, and the third power amplifier may all be electrically connected to the controller. The first power amplifier, the second power amplifier, and the third power amplifier may be electrically connected one-to-one to the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23. The controller may transmit a first signal, a second signal, and a third signal to the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23, respectively. This allows for independent control of the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23. The electronic device 1000 can control the first signal, the second signal, and the third signal through the controller, thereby controlling the operating state of the first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a, thus meeting different usage scenarios and requirements.

[0225] In some implementations, when the electronic device 1000 is in external speaker mode, the controller can send a first signal, a second signal, and a third signal to the first sound unit 21, the second sound unit 22, and the third sound unit 23 respectively. The first signal, the second signal, and the third signal are in phase, thereby controlling the first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a to vibrate in the same direction. This allows the sound emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 to be superimposed, thereby making the sound emitted by the speaker module 400 louder and meeting the user's loudness requirements when the electronic device 1000 is in external speaker mode.

[0226] In some implementations, when the electronic device 1000 is in call mode, the controller can send a first signal, a second signal, and a third signal to the first sound unit 21, the second sound unit 22, and the third sound unit 23, respectively. One of the first signal, the second signal, and the third signal is out of phase with the other two, thereby controlling the vibration direction of one of the first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a to be opposite to the vibration direction of the other two. This causes the sound emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 to cancel each other out in the far field, thereby achieving the sound leakage prevention effect of the electronic device 1000 and meeting the user's requirements for the sound leakage prevention function of the electronic device 1000 during calls.

[0227] Understandably, compared to typical dual-diaphragm speakers in electronic devices, which use two diaphragms positioned back-to-back (i.e., facing opposite directions), these speakers can create a quadrupole sound field to prevent sound leakage during voice calls. However, when the user uses the device for external playback, these speakers can only control the vibration of two diaphragms in the same direction, resulting in poor sound quality. This embodiment includes three sound-generating units (i.e., the first sound-generating unit 21, the second sound-generating unit 22, and the third sound-generating unit 23), and these three units can be controlled independently. On one hand, by controlling the amplitude and phase of the three sound-generating units, the sounds emitted by the three units can be better canceled in the far field, achieving sound leakage prevention. On the other hand, controlling the vibration of the three diaphragms of the three sound-generating units in the same direction can effectively improve the external playback performance of the electronic device 1000. In other words, the electronic device 1000 in this embodiment can simultaneously achieve good sound leakage prevention and external playback performance, resulting in a better user experience.

[0228] In some embodiments, the speaker module 400 may further include a fourth sound-emitting unit (not shown). The first housing 310 may also have a fourth sound outlet (not shown). The fourth sound-emitting unit can emit sound into the external space of the first housing 310 through the fourth sound outlet. The fourth sound outlet may be located at the top of the first housing 310. The fourth sound outlet may be spaced apart from the first sound outlet 311a, the second sound outlet 311b, and the third sound outlet 311c. The first sound outlet 311a and the second sound outlet 311b may be located between the third sound outlet 311c and the fourth sound outlet.

[0229] Understandably, on the one hand, the fourth sound unit provides an additional degree of freedom, improving the control precision of the electronic device 1000 when preventing sound leakage. Thus, when the speaker module is working, the sounds emitted by the first sound unit 21, the second sound unit 22, the third sound unit 23, and the fourth sound unit can cancel each other out in the far field, thereby improving the sound leakage prevention effect of the electronic device 1000, enhancing call privacy, and improving the user experience. On the other hand, in this embodiment, the third and fourth sound outlets of the electronic device 1000 are located on either side of the first and second sound outlets 311a and 311b, respectively. This prevents the user from simultaneously blocking both the third and fourth sound outlets when using the electronic device 1000 for calls, thus improving the stability of the sound leakage prevention.

[0230] In other embodiments, the fourth sound outlet may also be located at the bottom of the first housing 310. The fourth sound-emitting unit of the speaker module 400 can emit sound through the fourth sound outlet. In this way, when the user uses the audio and video functions of the electronic device 1000, the bottom of the electronic device 1000 can also achieve external playback through the fourth sound-emitting unit, which helps to improve the external playback effect of the electronic device 1000.

[0231] In some embodiments, the speaker module 400 may not include the module housing 10. In this case, the first sound-emitting unit 21, the second sound-emitting unit 22, the third sound-emitting unit 23, the first partition 113a, the second partition 113b, and the third partition 113c can all be located in the first mounting space 310a. The first partition 113a can be fixedly connected between the first housing 310 and the first sound-emitting unit 21. The first sound-emitting unit 21, together with the first housing 310 and the first partition 113a, can enclose a first space 30a. The second partition 113b can be fixedly connected between the first housing 310 and the second sound-emitting unit 22. The second sound-emitting unit 22, together with the first housing 310 and the second partition 113b, can enclose a second space 30b. The third partition 113c can be fixedly connected between the first housing 310 and the third sound-emitting unit 23. The third sound-emitting unit 23, together with the first housing 310 and the third partition 113c, can enclose a third space 30c. The first diaphragm 21a, the second diaphragm 22a, and the third diaphragm 23a are exposed relative to the first space 30a, the second space 30b, and the third space 30c, respectively. The first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23 can emit sound to the external space of the first housing 310 through the first space 30a, the second space 30b, and the third space 30c, respectively.

[0232] It is understood that the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23 of the electronic device in this embodiment can respectively enclose a first space 30a, a second space 30b, and a third space 30c with the first housing 310. In this way, the volumes of the first space 30a, the second space 30b, and the third space 30c are relatively large, that is, the vibration space of the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23 is relatively large, thereby improving the sound output effect of the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23, and thus improving the sound output effect of the electronic device 1000.

[0233] In other implementations, please refer to Figure 27 As shown, Figure 27 yes Figure 5b The illustrated electronic device 1000 is a partial structural diagram in other embodiments. The electronic device 1000 in this embodiment is different from... Figure 6The electronic device 1000 shown has a largely similar structure, and the similarities will not be repeated. The main differences are described below. In this embodiment, the first sound-emitting unit 21 and the second sound-emitting unit 22 can be placed vertically, and the third sound-emitting unit 23 can be placed horizontally. It should be understood that vertical placement means the long side of the sound-emitting unit is placed along the Y-axis, and horizontal placement means the long side of the sound-emitting unit is placed along the X-axis. This effectively reduces the space occupied by the sound-emitting units, making the layout of the electronic device 1000 more compact and facilitating the thinning of the electronic device 1000.

[0234] In some other embodiments, the electronic device 1000 may not include the third sound outlet 311c, and the speaker module 400 may not include the third sound-emitting unit 23.

[0235] Figure 28 yes Figure 5b The diagram shows an exploded view of the electronic device 1000 in another embodiment. Figure 29 yes Figure 28 The diagram shows the structure of the first housing 310. Figure 30 yes Figure 5b The diagram shows a partial cross-sectional view of the electronic device cut along point AA in another embodiment.

[0236] like Figures 28 to 30 As shown, the electronic device 1000 in this embodiment and Figure 6 The electronic device 1000 shown has a largely similar structure, and the similarities will not be repeated. The main differences are described below. In this embodiment, the connecting hole 315 can be formed in the frame 313 of the first housing 310. One end of the connecting hole 315 can connect to the second clearance groove 313e, thereby connecting to the second sound outlet 311b. The other end of the connecting hole 315 can penetrate through the first inner side surface 313a of the frame 313 to connect to the first mounting space 310a. The first mounting space 310a can connect to the second clearance groove 313e through the connecting hole 315. At this time, the first mounting space 310a can connect to the sound-emitting space 317 through the connecting hole 315. The first mounting space 310a can connect to the second sound outlet 311b through the connecting hole 315 and the sound-emitting space 317. That is, the first mounting space 310a can connect to the second sound outlet 311b through the second sound outlet pipe 314b.

[0237] For example, the connecting hole 315 can be spaced apart from the first sound outlet duct 314a, the second sound outlet duct 314b, and the third sound outlet duct 314c. The side of the first sound outlet duct 314a, the connecting hole 315, and the third sound outlet duct 314c that penetrates the first inner side surface 313a can be arranged side by side along the width direction of the speaker module 400 (i.e., the X-axis direction in this embodiment). In other embodiments, the arrangement of the first sound outlet duct 314a, the connecting hole 315, and the third sound outlet duct 314c can also be in other forms.

[0238] Figure 31 yes Figure 28 The diagram shows the structure of the speaker module 400. Figure 32 yes Figure 31 The diagram shows a partial cross-sectional view of one embodiment of the speaker module 400 cut along point KK.

[0239] like Figure 31 and Figure 32 As shown, the first hole 11a, the second hole 11b, and the third hole 11c can all be located in the frame portion 112 of the upper shell 11 of the speaker module 400. The first hole 11a, the second hole 11b, and the third hole 11c can all penetrate the inner and outer peripheral sides of the frame portion 112. The first hole 11a, the second hole 11b, and the third hole 11c can all be located on the same side of the frame portion 112. The first hole 11a, the second hole 11b, and the third hole 11c can be arranged side-by-side along the width direction of the speaker module 400 (i.e., the X-axis direction in this embodiment). In other embodiments, the first hole 11a, the second hole 11b, and the third hole 11c can also be located on different sides of the frame portion 112. The position and arrangement of the first hole 11a, the second hole 11b, and the third hole 11c can also be in other forms.

[0240] Exemplarily, the second diaphragm 22a, together with the top 111 of the module housing 10 and the second partition 113b, can enclose a second space 30b. The second hole 11b can communicate with the second space 30b. The second space 30b can communicate with the external space of the speaker module 400 through the second hole 11b. At least a portion of the second diaphragm 22a can be exposed relative to the second space 30b. When the speaker module 400 is operating, the second diaphragm 22a of the second sound-emitting unit 22 can push the air in the second space 30b, passing sequentially through the second space 30b and the second hole 11b, to emit sound into the external space of the speaker module 400.

[0241] Figure 33 yes Figure 5b The diagram shows a partial cross-sectional view of the electronic device 1000 cut along JJ in another embodiment.

[0242] like Figure 33 As shown, the second hole 11b can be positioned directly opposite the connecting hole 315. The second hole 11b can connect to the connecting hole 315. That is, the second sound outlet 314b can connect to the second hole 11b, and thus connect to the second space 30b. At this time, the second sound outlet 311b can connect to the second space 30b through the second sound outlet 314b and the second hole 11b. When the speaker module 400 is working, the second diaphragm 22a can push the air in the second space 30b, passing through the second space 30b, the second hole 11b, the second sound outlet 314b, and the second sound outlet 311b in sequence, to emit sound to the external environment of the electronic device 1000. That is, the second sound-emitting unit 22 can emit sound to the external environment of the electronic device 1000 in sequence through the second space 30b, the second hole 11b, the second sound outlet 314b, and the second sound outlet 311b.

[0243] Figure 34a This is a partial structural schematic diagram of the electronic device 1000 provided in another embodiment of the present application. Figure 34b yes Figure 34a The illustrated electronic device 1000 is a simplified schematic diagram in some embodiments.

[0244] like Figure 34a and Figure 34b As shown, the electronic device 1000 in this embodiment and Figure 6 The electronic device 1000 shown has a largely similar structure, and the similarities will not be repeated. The main differences are described below. In this embodiment, both the second sound outlet 311b and the third sound outlet 311c can be located at the top of the first housing 310. The first sound outlet 311a, the second sound outlet 311b, and the third sound outlet 311c can be arranged side-by-side along the X-axis. The second sound outlet 311b can be located between the first sound outlet 311a and the third sound outlet 311c. Both the second sound outlet 311b and the third sound outlet 311c can include three small holes arranged side-by-side.

[0245] For example, the first housing 310 may also have a first sound outlet duct 314a, a second sound outlet duct 314b, and a third sound outlet duct 314c arranged at intervals. One end of each of the first sound outlet duct 314a, the second sound outlet duct 314b, and the third sound outlet duct 314c can penetrate through the first inner side surface 313a of the frame 313 of the first housing 310 (see reference). Figure 9(As shown). The other ends of the first sound outlet duct 314a, the second sound outlet duct 314b, and the third sound outlet duct 314c can be connected one-to-one to the first sound outlet 311a, the second sound outlet 311b, and the third sound outlet 311c. The first sound outlet duct 314a, the second sound outlet duct 314b, and the third sound outlet duct 314c can be arranged side by side along the X-axis. The second sound outlet duct 314b can be located between the first sound outlet duct 314a and the third sound outlet 314c. When the speaker module 400 is working, the first sound-emitting unit 21 can emit sound to the external environment of the first housing 310 through the first sound outlet duct 314a and the first sound outlet 311a. The second sound-emitting unit 22 can emit sound to the external environment of the first housing 310 through the second sound outlet duct 314b and the second sound outlet 311b. The third sound-emitting unit 23 can emit sound to the external environment of the first housing 310 through the third sound outlet duct 314c and the third sound outlet 311c.

[0246] For example, the first sound outlet 311a can serve as a handset opening. When a user makes a call using the electronic device 1000, the first sound unit 21 can serve as a receiver. The first sound unit 21 can play the call audio. The sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 can cancel each other out in the far field, achieving a sound leakage prevention effect for the electronic device 1000.

[0247] It is understood that in this embodiment, the second sound outlet 311b and the third sound outlet 311c of the electronic device 1000 are both located on the top of the first housing 310 and are both positioned close to the first sound outlet 311a. In this way, the second sound outlet 311b and the third sound outlet 311c are relatively close to the first sound outlet 311a. When the speaker module 400 is working, the sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 can better cancel each other out in the far field, thereby improving the sound leakage prevention effect of the electronic device 1000.

[0248] Figure 35 This is a partial structural schematic diagram of the electronic device 1000 provided in another embodiment of the present application.

[0249] like Figure 35 As shown, the electronic device 1000 in this embodiment and Figure 34aThe electronic device 1000 shown has a largely similar structure, and the similarities will not be repeated. The main differences are described below. In this embodiment, the third sound outlet 311c can be located on the side of the first sound outlet 311a opposite to the second sound outlet 311b. The distance between the second sound outlet 311b and the first sound outlet 311a can be equal to the distance between the third sound outlet 311c and the first sound outlet 311a. It can be understood that the distance between the second sound outlet 311b and the first sound outlet 311a can refer to the distance between the midpoint of the second sound outlet 311b along the X-axis and the midpoint of the first sound outlet 311a along the X-axis. The distance between the third sound outlet 311c and the first sound outlet 311a can refer to the distance between the midpoint of the third sound outlet 311c along the X-axis and the midpoint of the first sound outlet 311a along the X-axis. Unless otherwise specified, the distances between the sound outlets 311 in the following text can be understood in the same way.

[0250] For example, the first sound outlet 311a can serve as a handset opening. When a user makes a call using the electronic device 1000, the first sound unit 21 can serve as a receiver. The first sound unit 21 can play the call audio. The sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 can cancel each other out in the far field, achieving a sound leakage prevention effect for the electronic device 1000.

[0251] Understandably, compared to electronic devices where both the second and third sound output ports are located on the same side of the first sound output port, users are more likely to block these ports when making calls, thus affecting the sound output and leakage prevention performance of the electronic device 1000. However, in this embodiment, the second sound output port 311b and the third sound output port 311c of the electronic device 1000 are located on opposite sides of the first sound output port 311a. This prevents users from blocking both the second and third sound output ports 311b and 311c simultaneously when making calls, thereby improving the stability of the electronic device 1000's leakage prevention performance.

[0252] Furthermore, in this embodiment, the distance between the second sound outlet 311b and the first sound outlet 311a in the electronic device 1000 can be equal to the distance between the third sound outlet 311c and the first sound outlet 311a. Thus, when the speaker module 400 is operating, the sound emitted from the second sound outlet 311b and the sound emitted from the third sound outlet 311c are relatively symmetrical, allowing the sounds emitted from the first sound unit 21, the second sound unit 22, and the third sound unit 23 to better cancel each other out in the far field, improving the sound leakage prevention effect of the electronic device 1000.

[0253] Figure 36This is a partial structural schematic diagram of the electronic device 1000 provided in another embodiment of the present application.

[0254] like Figure 36 As shown, the electronic device 1000 in this embodiment and Figure 6 The electronic device 1000 shown has a largely similar structure, and the similarities will not be repeated. The main differences between the two will be described below. In this embodiment, the second housing 320 may also have a second mounting space 320a. The third sound-emitting unit 23 may be located in the second mounting space 320a. Both the third sound outlet 311c and the third sound outlet 314c may be formed in the second housing 320. The second mounting space 320a can be connected to the external space of the second housing 320 through the third sound outlet 314c and the third sound outlet 311c. When the speaker module 400 is working, the third sound-emitting unit 23 can emit sound to the external environment through the third sound outlet 314c and the third sound outlet 311c.

[0255] For example, the first sound outlet 311a can serve as a handset slit. When a user makes a call using the electronic device 1000, the first sound unit 21 can serve as a receiver and can play the call audio. When the electronic device 1000 is in the open state, the sound emitted by the second sound unit 22 can cancel out the sound emitted by the first sound unit 21 in the far field, thereby achieving a sound leakage prevention effect when the electronic device 1000 is in the open state. When the electronic device 1000 is in the closed state, the sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 can cancel out each other in the far field, thereby achieving a sound leakage prevention effect when the electronic device 1000 is in the closed state.

[0256] Understandably, compared to electronic devices where the first, second, and third sound outlets are all located in the same housing, the manufacturing difficulty and processing cost of the housing are greater. However, in this embodiment, the first sound outlet 311a and the second sound outlet 311b of the electronic device 1000 are located in the first housing 310, while the third sound outlet 311c is located in the second housing 320. That is, the first sound outlet 311a, the second sound outlet 311b, and the third sound outlet 311c can be formed in two different housings. This reduces the processing difficulty of the housing 300 of the electronic device 1000, thereby reducing the processing cost of the electronic device 1000.

[0257] Figure 37 This is a partial structural schematic diagram of the electronic device 1000 provided in another embodiment of the present application.

[0258] like Figure 37 As shown, the electronic device 1000 in this embodiment and Figure 6 The electronic device 1000 shown has a largely similar structure, and the similarities will not be repeated. The main differences are described below. In this embodiment, the first housing 310 and the second housing 320 can be arranged side-by-side along the Y-axis. In this case, the electronic device 1000 can be considered a small folding structure. The first sound outlet 311a, the second sound outlet 311b, and the third sound outlet 311c can be located on the side of the first housing 310's frame 313 facing away from the second housing 320. The first sound unit 21, the second sound unit 22, and the third sound unit 23 can be located inside the first housing 310. The first sound unit 21, the second sound unit 22, and the third sound unit 23 can be positioned away from the second housing 320.

[0259] For example, when the electronic device 1000 is in a closed state, the first sound outlet 311a can serve as an outer screen earpiece slit. When a user uses the electronic device 1000 to make a call, the first sound unit 21 can serve as a receiver, and the first sound unit 21 can play the call audio. At this time, the sounds emitted by the first sound unit 21, the second sound unit 22, and the third sound unit 23 can cancel each other out in the far field, thereby achieving a sound leakage prevention effect when the electronic device 1000 is in a closed state.

[0260] For example, when the electronic device 1000 is in the open state, the second sound outlet 311b can serve as an inner screen earpiece slit. When the user uses the electronic device 1000 to make a call, the second sound unit 22 can serve as a receiver, and the second sound unit 22 can play the call audio. At this time, the sound emitted by the first sound unit 21, the sound emitted by the second sound unit 22, and the sound emitted by the third sound unit 23 can cancel each other out in the far field, thereby achieving a sound leakage prevention effect when the electronic device 1000 is in the open state.

[0261] It is understood that when the electronic device 1000 in this embodiment is in the open state, the user can use the inner screen earpiece slot (which is also the second audio output port 311b in this embodiment) to make calls. When the electronic device 1000 is in the closed state, the user can use the outer screen earpiece slot (which is also the first audio output port 311a in this embodiment) to make calls. In this way, regardless of whether the electronic device 1000 is in the open or closed state, the user can use the corresponding earpiece slot to make calls, resulting in a better user experience.

[0262] In some embodiments, a sound-emitting unit may also be provided in the second housing 320. When the electronic device 1000 is working, the sound emitted by the sound-emitting unit in the second housing 320 can cancel out the sound emitted by the first sound-emitting unit 21, the second sound-emitting unit 22, and the third sound-emitting unit 23, thereby improving the sound leakage prevention effect of the electronic device 1000.

[0263] In other embodiments, the shape, size, and arrangement of the first sound outlet 311a, the second sound outlet 311b, and the third sound outlet 311c can also be other forms. Similarly, the shape, size, and arrangement of the first sound outlet duct 314a, the second sound outlet duct 314b, and the third sound outlet duct 314c can also be other forms. For example, the sound outlets 311 and ducts 314 can be located anywhere on the electronic device 1000 (such as on the inner or outer screen, the middle frame (main frame or sub-frame), the battery cover, or the lens).

[0264] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0265] It should be noted that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0266] The above are merely some embodiments of this application, and the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
