Description

Technical Field

[0001] This application relates to the field of audio technology, and more particularly to an electronic device. Background Technology

[0002] Audio functionality is a crucial feature of mobile phones and other electronic devices, significantly impacting the user experience. Electronic devices are used in scenarios involving low volume, such as during calls, where sound leakage prevention is essential for privacy; and in scenarios involving high volume, such as when speaking aloud, where loudness is crucial. However, current electronic devices offer limited audio functionality, making it difficult to balance privacy and loudness simultaneously. Summary of the Invention

[0003] The purpose of this application is to provide an electronic device that can balance privacy and loud speaker volume, resulting in a better user experience.

[0004] In a first aspect, this application provides an electronic device, including a housing assembly, a first speaker module, and a display screen. The display screen and the first speaker module are both mounted on the housing assembly. The first speaker module includes a first diaphragm, a second diaphragm, and a third diaphragm. The electronic device also includes a first sound outlet, a second sound outlet, and a third sound outlet. When the first diaphragm vibrates, sound is emitted through the first sound outlet. When the second diaphragm vibrates, sound is emitted through the second sound outlet. When the third diaphragm vibrates, sound is emitted through the third sound outlet. The first sound outlet, the second sound outlet, and the third sound outlet are located at least one of the housing assembly, between the housing assembly and the display screen, or within the display screen. The opening directions of the first sound outlet, the second sound outlet, and the third sound outlet are different.

[0005] For example, the first sound outlet can be used as the main sound outlet.

[0006] For example, the opening direction of the first sound outlet can be parallel to the thickness direction of the middle frame. The opening direction of the second sound outlet can be parallel to the length direction of the middle frame. The opening direction of the third sound outlet can be parallel to the length direction of the middle frame. The opening directions of the second and third sound outlets can be approximately perpendicular.

[0007] For example, the first sound outlet, the second sound outlet, or the third sound outlet can all be micro-slits or openings.

[0008] In this embodiment, on the one hand, by setting a first, second, and third sound outlet with different sound output directions, it is beneficial to coordinate the sound waves emitted from multiple sound outlets in different directions, enabling the electronic device to mute sound from a specific direction when emitting sound, thus avoiding sound leakage problems in scenarios such as phone calls. Furthermore, since the three sound outlets have different sound output directions, at least two of them can be used for sound mute, thus enabling sound mute from multiple directions and providing a better anti-leakage effect. On the other hand, the setting of the first, second, and third sound outlets with different sound output directions also facilitates the electronic device to emit sound from multiple directions, which is beneficial for the coordination of sound waves from multiple sound outlets, thereby increasing the loudness of the electronic device's sound output. Therefore, the electronic device of this application can balance privacy and loudness during use, resulting in a better user experience.

[0009] In some embodiments, the housing assembly includes a frame and a back cover, the back cover being disposed opposite to the display screen, and the frame being fixedly connected to the display screen and the back cover; a first sound outlet is disposed between the frame and the display screen, or on the display screen, or on the frame; a second sound outlet and a third sound outlet are both disposed on the frame, or one of the second sound outlet and the third sound outlet is disposed on the frame and the other on the back cover; or one of the second sound outlet and the third sound outlet is disposed on the back cover and the other is disposed between the back cover and the frame.

[0010] In some embodiments, the first sound outlet is located between the frame and the display screen, and is located on the top side of the display screen; the second and third sound outlets are both located on the frame, the second sound outlet is located on the first side of the frame, the first side is located on the top side of the display screen, and the third sound outlet is located on the second side of the frame, the second side is connected to the first side.

[0011] In this embodiment, both the second and third sound outlets are located on the frame. The second and third sound outlets are easily formed in the same or similar manner, and the channels from the second diaphragm to the second sound outlet and from the third diaphragm to the second sound outlet are also easily formed in similar manner, which helps to simplify the sound output structure of the electronic device.

[0012] In some embodiments, the housing assembly includes a middle frame and a rear cover, the rear cover being fixed to the middle frame, and a first speaker module located on the side of the middle frame facing away from the display screen; a first diaphragm is connected to a first sound outlet through a first sound outlet channel, a second diaphragm is connected to a second sound outlet through a second sound outlet channel, and a third diaphragm is connected to a third sound outlet through a third sound outlet channel, wherein the first, second, and third sound outlet channels are not interconnected; wherein the middle frame and the display screen are used to form the first, second, or third sound outlet channel; or the housing assembly further includes a bracket, the bracket being fixedly connected to the middle frame and used to form the first, second, or third sound outlet channel; or the housing assembly further includes a bracket, the bracket being fixedly connected to the rear cover and forming the first, second, or third sound outlet channel.

[0013] In this embodiment, when the first sound output channel, the second sound output channel, and the third sound output channel are all enclosed by the middle frame and the display screen, the main space of the first sound output channel can be easily formed directly in the middle frame by slotting and drilling, without the need to set up additional structural components to separately enclose the first sound output channel, which helps to simplify the structure of the housing assembly and electronic device.

[0014] When the bracket and the middle frame are used to form a second or third sound output channel, it is easier to set the shape of the channel according to the sound output requirements and reduce the restriction of the middle frame on the shape of the second or third sound output channel.

[0015] When the bracket and the back cover are used to form a second or third sound channel, it is easier to set the shape of the channel according to the sound output requirements and reduce the restriction of the middle frame on the shape of the second or third sound channel.

[0016] In some embodiments, the housing assembly includes a mid-frame and a rear cover, with the rear cover fixed to the mid-frame. The first speaker module is located on the side of the mid-frame facing away from the display screen. The first diaphragm is connected to the first sound outlet through a first sound outlet channel, the second diaphragm is connected to the second sound outlet through a second sound outlet channel, and the third diaphragm is connected to the third sound outlet through a third sound outlet channel. The first, second, and third sound outlet channels are not connected to each other. The first, second, and third sound outlet channels are all enclosed by the mid-frame and the display screen.

[0017] In this embodiment, the display screen and the mid-frame can directly form three independent sound channels, reducing the number of components in the electronic device and minimizing the space occupied by forming the three sound channels. This makes the structure of the electronic device more rational and facilitates its thinner design. Furthermore, since there is no need for supports or other structures to form the three sound channels, there is no pressure exerted on the mid-frame by supports or other structures. This makes the stress on the mid-frame more reasonable, easier to keep flat, and provides better support for the display screen.

[0018] In some embodiments, the middle frame is provided with a first connecting slot, a second connecting slot and a third connecting slot, all of which are located on the side of the middle frame facing the display screen. The display screen is sealed to the middle frame and covers the first connecting slot, the second connecting slot and the third connecting slot, so that the first connecting slot is used to form a first sound output channel, the second connecting slot is used to form a second sound output channel and the third connecting slot is used to form a third sound output channel.

[0019] In this embodiment, the first connecting slot, the second connecting slot, and the third connecting slot are all located on the same side of the middle frame, which facilitates the manufacturing and processing of the middle frame and allows the first connecting slot, the second connecting slot, and the third connecting slot to directly form corresponding sound output channels with the display screen, making the assembly of the electronic device relatively simple.

[0020] In some embodiments, the middle frame has a first through hole, a second through hole, and a third through hole. The first through hole connects to a first sound outlet channel, the second through hole connects to a second sound outlet channel, and the third through hole connects to a third sound outlet channel. The first speaker module includes a core and a shell. The shell is fixedly connected to the core and forms a first cavity for the first diaphragm to produce sound, a second cavity for the second diaphragm to produce sound, and a third cavity for the third diaphragm to produce sound. The shell has a first sound outlet connecting to the first cavity, a second sound outlet connecting to the second cavity, and a third sound outlet connecting to the third cavity. The second diaphragm faces the second sound outlet, and the third diaphragm faces the third sound outlet. The orientation of the first diaphragm is opposite to that of the second diaphragm. The first, second, and third sound outlets all face the surface of the middle frame. The first sound outlet is connected to the first through hole, the second sound outlet is connected to the second through hole, and the third sound outlet is connected to the third through hole.

[0021] For example, in the width direction of the middle frame, the third through hole, the second through hole, and the first through hole can be arranged sequentially. In the length direction of the middle frame, the first through hole, the second through hole, and the third through hole can be arranged sequentially.

[0022] In this embodiment, since the first sound outlet, the second diaphragm, and the third diaphragm all face the surface of the middle frame (i.e., the middle plate), and the first, second, and third sound outlets have the same orientation, they all emit sound towards the surface of the middle frame in the first speaker module. At this time, the first speaker module can easily form a space directly with the middle frame through its own structure, thereby connecting the first diaphragm to the first sound outlet channel, the second diaphragm to the second sound outlet channel, and the third diaphragm to the third sound outlet channel. No other components are needed to form the front sound cavity, thus reducing the number of components in the electronic device.

[0023] The second and third diaphragms face the middle frame, while the first diaphragm faces in the opposite direction. Therefore, since the second and third diaphragms directly face the middle frame (i.e., the middle plate), there is no need to add a deflecting cavity structure in the first speaker module to guide and change the direction of sound propagation from the second and third diaphragms. This simplifies the structure of the first speaker module and reduces the width occupied by the cavity structure used for sound transmission, facilitating further miniaturization of the first speaker module and reducing its space requirement in electronic devices.

[0024] In some implementations, the first speaker module includes a core, and the first diaphragm, the second diaphragm, and the third diaphragm are located in the same core.

[0025] In this embodiment, when multiple diaphragms are located in one core, it is beneficial to reuse multiple support structures, magnetic circuit structures, etc., thereby greatly reducing the volume of the first speaker module, which is conducive to its further application in miniaturized and thin electronic devices.

[0026] In some embodiments, the second diaphragm and the third diaphragm are arranged side by side, both of which face away from the first diaphragm. The area of ​​the first diaphragm is larger than that of the second diaphragm and also larger than that of the third diaphragm.

[0027] In this embodiment, given a certain volume of the first speaker module, the area of ​​the first diaphragm can be easily set to be larger, resulting in a louder sound and higher sound quality. The second and third diaphragms can also be set to be larger, which is beneficial to improving the sound quality of the first speaker module.

[0028] In some embodiments, the electronic device has a first operating mode and a second operating mode; when the electronic device is in the first operating mode, the second diaphragm and the third diaphragm vibrate in phase, and the second diaphragm and the third diaphragm vibrate in opposite phase to the first diaphragm; when the electronic device is in the second operating mode, the first diaphragm, the second diaphragm and the third diaphragm vibrate in phase.

[0029] The second and third diaphragms vibrate in opposite phase to the first diaphragm, and both the second and third diaphragms form an acoustic dipole with the first diaphragm.

[0030] In this embodiment, the three diaphragms of the first speaker module can vibrate and emit sound through the first, second, and third sound outlets. One of the three sound outlets is used for normal sound emission, while the other two sound outlets can be used to mute the other sound outlet, preventing sound leakage from the electronic device in the opening directions of the two sound outlets used for mute. This reduces sound leakage from the electronic device in multiple directions. In quiet or confined call scenarios, the user's conversation is less likely to be heard by people nearby, greatly improving the privacy and security of the electronic device during calls.

[0031] Furthermore, the first, second, and third diaphragms vibrate in phase, resulting in a louder sound from the electronic device, which is beneficial for improving the external sound effect.

[0032] In some embodiments, the electronic device further includes a second speaker module and has a fourth sound outlet; the second speaker module is mounted on the housing assembly and emits sound through the fourth sound outlet.

[0033] For example, the second speaker module can cooperate with the first speaker module, and the diaphragm of the second speaker module can vibrate in opposite phase to the first diaphragm, thereby forming a pair of acoustic dipoles with the first diaphragm. In this case, the second speaker module can further reduce noise, thereby improving the sound leakage prevention range and effect of the electronic device.

[0034] When the electronic device is in the second working mode, the second speaker module can cooperate with the first speaker module, and the diaphragm of the second speaker module can vibrate in phase with the first diaphragm, thereby further improving the loudness of the electronic device's external sound output and enhancing the external sound output effect.

[0035] In this embodiment, the first speaker module and the second speaker module can be used together to enable the electronic device to have richer audio functions.

[0036] In some embodiments, in the sound emission path from the first diaphragm to the first sound outlet, the minimum cross-sectional area of ​​the sound emission path is greater than or equal to 3 square millimeters; in the sound emission path from the second diaphragm to the second sound outlet, the minimum cross-sectional area of ​​the sound emission path is greater than or equal to 3 square millimeters; and in the sound emission path from the third diaphragm to the third sound outlet, the minimum cross-sectional area of ​​the sound emission path is greater than or equal to 3 square millimeters.

[0037] In this embodiment, the airflow resistance of the first, second, and third sound output channels is small, resulting in less noise during sound propagation and thus enabling the electronic device to have better sound quality.

[0038] In some embodiments, the area of ​​the first sound outlet is greater than or equal to 6 square millimeters, the area of ​​the second sound outlet is greater than or equal to 3 square millimeters, and the area of ​​the third sound outlet is greater than or equal to 3 square millimeters.

[0039] In this embodiment, the areas of the first sound outlet, the second sound outlet, and the third sound outlet are all relatively large, so that all three can output sound smoothly and improve the sound quality of the electronic device. Attached Figure Description

[0063] The embodiments of this application are described below with reference to the accompanying drawings.

[0064] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," "joining," and "joining" should be interpreted broadly. For example, "joining" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Movable connection" refers to a connection where the relative positional relationship can change after connection. "Rotary connection" refers to a connection where the relative positional relationship can change. "Sliding connection" refers to a connection where the relative positional relationship can change. Furthermore, the integrated structure obtained by a one-piece molding process means that during the formation of one of the two components, that component is connected to the other component without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to connect the two components. Components A and B can be arranged relative to each other such that component A is projected along the target direction to obtain projection C, and component B is projected along the target direction to obtain projection D, with projection C and projection D at least largely overlapping. In some embodiments, the majority overlap can be any of the following: projection C is entirely within projection D; or projection D is entirely within projection C; or projection C and projection D intersect each other, and the intersection area of ​​projection C and projection D accounts for more than 50% of projection C or projection D.

[0065] The directional terms mentioned in the embodiments of this application, such as "top," "bottom," "inner," "outer," "upper," and "lower," 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 are not intended to 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. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0066] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship. "Multiple" means at least two.

[0067] Furthermore, the limitations on relative positional relationships mentioned in the embodiments of this application, such as parallelism and perpendicularity, are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0068] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an electronic device 10 provided in an embodiment of this application. Figure 2 yes Figure 1 An exploded view of a portion of the structure of the electronic device 10 shown. Wherein, Figure 2 yes Figure 1 A schematic diagram of the decomposition structure of region A in the middle.

[0069] In this embodiment, the electronic device 10 can be a mobile phone, tablet computer, multimedia player, headphones, speaker, laptop computer, in-vehicle equipment, foldable terminal device, television, or wearable device, etc., that has audio playback capabilities. Wearable devices can include smart bracelets, smartwatches, smart headsets, smart glasses, etc. Figure 1 The electronic device 10 shown in the embodiment is illustrated using a mobile phone as an example. Of course, other types of electronic devices 10 can also adopt a similar structure, which will not be described in detail below.

[0070] For ease of description, the width direction of the electronic device 10 is defined as the X direction, the length direction as the Y direction, and the thickness direction as the Z direction.

[0071] In some embodiments, the electronic device 10 may include a housing assembly 1, a display screen 2, and a first speaker module 3. The housing assembly 1 may include a mid-frame 11 and a rear cover 12. The rear cover 12, the first speaker module 3, the mid-frame 11, and the display screen 2 may be stacked sequentially. In this embodiment, in the electronic device 10, the side facing the display screen 2 is the "front," the side facing the rear cover 12 is the "back," the end where the first speaker module 3 is located is the "top," and the other end is the "bottom."

[0072] For example, the middle frame 11 can be generally rectangular in shape, and the shape of the middle frame 11 can be approximately the same as the shape of the electronic device 10. The middle frame 11 can serve as the main structural component of the electronic device 10 to support and mount the various components of the electronic device 10. The middle frame 11 can form multiple slots or chambers to mount the components of the electronic device 10.

[0073] The middle frame 11 can be formed by splicing and assembling multiple components, which simplifies the molding process when the structure of the middle frame 11 is complex. The main material of the middle frame 11 can be a metal, such as aluminum alloy, magnesium alloy, stainless steel, or titanium alloy. The middle frame 11 may also have plastic inserts, but this example does not strictly limit this. In other examples, the main material of the middle frame 11 can be plastic.

[0074] For example, the display screen 2 can be fixedly connected to one side of the middle frame 11. For instance, the display screen 2 can be fixedly connected to the middle frame 11 by means of adhesive, snap-fit, or other methods.

[0075] The display screen 2 can be electrically connected to the middle frame 11 to ground the display screen 2, thereby protecting the display screen 2.

[0076] Among them, the display screen 2 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0077] In this embodiment, the display screen 2 can be a flat screen, and its area can occupy most of the area of ​​the middle frame 11 to achieve a better display effect. In other embodiments, the display screen 2 can be a curved screen, a foldable screen, or a flexible screen, which can be set according to the needs of the electronic device 10. This embodiment does not impose strict limitations on this.

[0078] For example, the first speaker module 3 may be located inside the electronic device 10. The first speaker module 3 may serve as the earpiece of the electronic device 10. The inside of the electronic device 10 may be the mounting space enclosed by the housing assembly 1 and the display screen 2.

[0079] The first speaker module 3 can be located on the top side of the electronic device 10. The first speaker module 3 can be fixedly mounted on the middle frame 11. The electronic device 10 can have a sound outlet channel, which communicates with the external environment through a sound outlet, and the first speaker module 3 transmits sound to the external environment through the sound outlet channel. The sound outlet can be located at the end of the top side of the electronic device 10 to facilitate its opening.

[0080] The first speaker module 3 may have a diaphragm. The first speaker module 3 can be energized and drive the diaphragm to produce sound. When the first speaker module 3 is connected to alternating current with different characteristics (such as frequency and voltage), the diaphragm can produce sound at the corresponding frequency and loudness, thereby emitting the desired sound. For example, the diaphragm may be exposed relative to the first speaker module 3 to facilitate sound production. It is understood that the diaphragm may be connected to the sound outlet channel so that the diaphragm can vibrate the air in the sound outlet channel to produce sound.

[0081] For example, the back cover 12 can be fixedly connected to the side of the middle frame 11 facing away from the display screen 2. For example, the back cover 12 can be fixedly connected to the middle frame 11 by means of adhesive, snap-fit, etc.

[0082] The middle frame 11 may have a mounting groove (not shown), and the rear cover 12 can be installed in the mounting groove. The rear cover 12 closes the side of the middle frame 11 connected to it, thereby protecting the components between the rear cover 12 and the middle frame 11. The rear cover 12 can be sealed to the middle frame 11 to prevent water, dust, and other impurities from the outside of the electronic device 10 from entering the inside of the electronic device 10, thereby achieving waterproof and dustproof protection for the electronic device 10.

[0083] The back cover 12 can be roughly rectangular in shape, and the area of ​​the back cover 12 can be roughly the same as the area of ​​the middle frame 11.

[0084] The material of the back cover 12 can be glass, ceramic, metal, etc., and this embodiment does not impose strict limitations on it.

[0085] In some embodiments, the electronic device 10 may further include a front-facing camera 4, which is located inside the electronic device 10.

[0086] The front-facing camera 4 can be located at the top center of the electronic device 10, and the front-facing camera 4 can be mounted on the mid-frame 11.

[0087] The top of the display screen 2 may have a light-transmitting hole, which may be set to correspond with the light-intake sheet of the front camera 4, so that external light can pass through the light-transmitting hole and enter the front camera 4 through the light-intake sheet.

[0088] Understandably, the number of front-facing cameras 4 can be one or more. For example, the number of front-facing cameras 4 can be two or three, and in this case, the number of light-transmitting holes can be set to two or three respectively.

[0089] It is understood that the electronic device 10 may also include a rear camera, which may be located inside the electronic device 10. This embodiment does not strictly limit the structure of the rear camera.

[0090] In some embodiments, the electronic device 10 may further include a second speaker module 5 located on the bottom side. The second speaker module 5 is mounted on the housing assembly 1. The first speaker module 3 on the top side and the second speaker module 5 on the bottom side can emit sound simultaneously, thus creating stereo sound. Of course, the first speaker module 3 on the top side and the second speaker module 5 on the bottom side can also emit sound independently to meet different usage scenarios. Therefore, the first speaker module 3 and the second speaker module 5 can cooperate to give the electronic device 10 richer audio functions.

[0091] In some embodiments, the electronic device 10 may further include a circuit board assembly (not shown). The circuit board assembly may be located between the rear cover 12 and the middle frame 11, and the rear cover 12, the circuit board assembly, and the middle frame 11 may be stacked sequentially. The circuit board assembly may be communicatively connected to the display screen 2, the first speaker module 3, and the front-facing camera 4, so that the circuit board assembly can control the three. The structure of the circuit board assembly is not strictly limited in this embodiment.

[0092] In some embodiments, the electronic device 10 may further include multiple modules (not shown in the figures), which may be housed in the middle frame 11. The multiple modules of the electronic device 10 may include, but are not limited to, a battery, an earpiece module, a microphone module, a sensor module, etc. The embodiments of this application do not specifically limit the number, type, or location of the modules of the electronic device 10.

[0093] Please refer to the following: Figure 1 and Figure 3 , Figure 3 yes Figure 1 A schematic diagram of the structure of the electronic device 10 shown from another perspective.

[0094] In some embodiments, the electronic device 10 may have a first sound outlet 101, a second sound outlet 102, and a third sound outlet 103, wherein the first sound outlet 101, the second sound outlet 102, and the third sound outlet 103 are used for sound output from the first speaker module 3.

[0095] In some embodiments, the sound emission directions of the first sound outlet 101, the second sound outlet 102, and the third sound outlet 103 are different; that is, any two of the first sound outlet 101, the second sound outlet 102, and the third sound outlet 103 have different opening directions on the electronic device 10. In this embodiment, the opening direction or sound emission direction of the "sound outlet" refers to one direction. If the opening direction or sound emission direction is parallel but opposite, then the opening direction or sound emission direction is also different.

[0096] For example, the sound output direction or opening direction of the first sound outlet 101, the second sound outlet 102 and the third sound outlet 103 are perpendicular to each other, but this is not strictly limited.

[0097] For example, the opening direction of the first sound outlet 101 can be parallel to the thickness direction of the electronic device 10; that is, the opening direction of the first sound outlet 101 is perpendicular to the display screen 2. For example, the opening method of the first sound outlet 101 is in the +Z direction. For example, the first sound outlet 101 and the display screen 2 can be located on the same side of the housing assembly 1, in which case the orientation of the first sound outlet 101 is the same as the orientation of the display screen 2.

[0098] For example, the opening direction of the second sound outlet 102 can be parallel to the length direction of the electronic device 10. For instance, the opening direction of the second sound outlet 102 is the -Y direction. The opening direction of the third sound outlet 103 can be parallel to the width direction of the electronic device 10. For instance, the opening direction of the third sound outlet 103 is the -X direction.

[0099] In other examples, the opening direction of one of the second sound outlet 102 and the third sound outlet 103 may be parallel to the thickness direction of the electronic device 10 and opposite to the opening direction of the first sound outlet 101. For example, one of the second sound outlet 102 and the third sound outlet 103 may be located on the rear cover 12 and face away from the display screen 2 in the electronic device 10.

[0100] In some embodiments, the first sound outlet 101 can serve as the main sound outlet, and the orientation of the first sound outlet 101 can be the same as the orientation of the display screen 2. The second sound outlet 102 and the third sound outlet 103 can be auxiliary sound outlets with different opening directions than the first sound outlet 101.

[0101] For example, the first sound outlet 101 can be located between the frame 111 and the display screen 2, that is, the first sound outlet 101 can be surrounded by the frame 111 and the display screen 2. Alternatively, the first sound outlet 101 can be located on the display screen 2, that is, it has an opening on the display screen 2. Alternatively, the first sound outlet 101 can be located on the frame 111, that is, it has an opening on the frame 111.

[0102] For example, the second sound outlet 102 and the third sound outlet 103 are both located on the frame 111, or one of the second sound outlet 102 and the third sound outlet 103 is located on the frame 111 and the other is located on the back cover 12.

[0103] For example, the first sound outlet 101 may be an elongated microslit. Alternatively, the first sound outlet 101 may be a single opening, and the shape of the opening may be such as elliptical, racetrack-shaped, circular, irregular, etc. Alternatively, the first sound outlet 101 may also include multiple smaller openings.

[0104] In this embodiment, the first sound outlet 101 is located on the front of the electronic device 10, which facilitates sound output from the front; the second sound outlet 102 and the third sound outlet 103 are located on the side or back of the electronic device 10, so that sound can be output from different directions in the electronic device 10.

[0105] In some embodiments, the area of ​​the first sound outlet 101 is greater than or equal to 6 square millimeters, the area of ​​the second sound outlet 102 is greater than or equal to 3 square millimeters, and the area of ​​the third sound outlet 103 is greater than or equal to 3 square millimeters. In this case, the areas of the first sound outlet 101, the second sound outlet 102, and the third sound outlet 103 are all relatively large, so that all three can output sound smoothly and improve the sound quality of the electronic device 10. Furthermore, the area of ​​the first sound outlet 101 should be as large as possible to facilitate its use as the primary sound outlet. For example, the length of the first sound outlet 101 can be greater than 5 millimeters, the width can be greater than 0.25 millimeters, and the effective sound output area can be greater than 9 millimeters.

[0106] In some embodiments, a fourth sound outlet 104 may be provided on the bottom side of the electronic device 10. The fourth sound outlet 104 may be located on the bottom side of the electronic device 10, and the second speaker module 5 emits sound through the fourth sound outlet 104.

[0107] In some embodiments, the first speaker module 3 may have three diaphragms: a first diaphragm 311, a second diaphragm 312, and a third diaphragm 313. The three diaphragms emit sound independently through a first sound outlet 101, a second sound outlet 102, and a third sound outlet 103, respectively. For example, the first sound outlet 101, the second sound outlet 102, and the third sound outlet 103 are connected to different diaphragms through different channels, so that the three sound outlets serve as the sound outlets for the three diaphragms. The three diaphragms may belong to the same first speaker module 3.

[0108] The first diaphragm 311, the second diaphragm 312, and the third diaphragm 313 can be arranged opposite each other or side by side. This embodiment does not impose specific restrictions on the arrangement of the three diaphragms.

[0109] In some embodiments, the electronic device 10 may have a first operating mode, also called a sound leakage prevention mode. In this mode, the second diaphragm 312 and the third diaphragm 313 vibrate in opposite phase to the first diaphragm 311, and both the second diaphragm 312 and the third diaphragm 313 form an acoustic dipole with the first diaphragm 311. The three diaphragms of the first speaker module 3 can vibrate and emit sound through the first sound outlet 101, the second sound outlet 102, and the third sound outlet 103. One of these outlets is used for normal sound emission, while the other two outlets can be used to mute the other outlet, preventing sound leakage from the electronic device 10 in the opening directions of the two mute outlets. This reduces sound leakage from the electronic device 10 in multiple directions. In quiet or confined communication scenarios, the user's conversation is less likely to be heard by people nearby, significantly improving the privacy and security of the electronic device 10 during conversations.

[0110] For example, the first sound outlet 101 can be used as the main sound outlet, and the second sound outlet 102 and the third sound outlet 103 can be used as sound outlets for noise reduction.

[0111] Those skilled in the art will understand that the principle of noise reduction in electronic device 10 can be that the three diaphragms, through phase coordination during vibration, superimpose and cancel out sound waves in a specific direction, thereby canceling out sound in that specific direction and achieving noise reduction.

[0112] In some embodiments, the electronic device 10 may also have a second operating mode, also called an external speaker mode. In this mode, the three diaphragms of the first speaker module 3 can vibrate in phase, that is, the first diaphragm 311, the second diaphragm 312, and the third diaphragm 313 vibrate in phase, thereby making the loudness of the sound emitted by the electronic device 10 higher and improving the sound effect of external speaker playback.

[0113] It is understood that the electronic device 10 may also have other sound playback modes, and this embodiment does not specifically limit them.

[0114] In this embodiment, on the one hand, by setting a first sound outlet 101, a second sound outlet 102, and a third sound outlet 103 with different sound output directions, it is beneficial to coordinate the sound waves emitted from multiple sound outlets in different directions, so that the electronic device 10 can mute sound in a specific direction when it emits sound, avoiding sound leakage problems in scenarios such as phone calls; and since the sound output directions of the three sound outlets are different, at least two sound outlets can be used for mute, thus enabling mute from multiple directions and having a good anti-leakage effect; on the other hand, the setting of the first sound outlet 101, the second sound outlet 102, and the third sound outlet 103 with different sound output directions also facilitates the electronic device 10 to emit sound from multiple directions, which is beneficial to the coordination of sound waves from multiple sound outlets, thereby increasing the loudness of the sound emitted by the electronic device 10. Therefore, the electronic device 10 of this application has strong privacy and loudness when used, resulting in a better user experience.

[0115] In some embodiments, when the electronic device 10 is in the first operating mode, the second speaker module 5 can cooperate with the first speaker module 3, and the diaphragm of the second speaker module 5 can vibrate in opposite phase to the first diaphragm 311, thereby forming a pair of acoustic dipoles with the first diaphragm 311. At this time, the second speaker module 5 can further reduce noise, thereby improving the sound leakage prevention range and sound leakage prevention effect of the electronic device 10.

[0116] When the electronic device 10 is in the second working mode, the second speaker module 5 can cooperate with the first speaker module 3, and the diaphragm of the second speaker module 5 can vibrate in phase with the first diaphragm 311, thereby further improving the loudness of the external sound emitted by the electronic device 10 and improving the external sound effect.

[0117] Please see Figure 4 , Figure 4 yes Figure 1 The diagram shows a partial structure of the electronic device 10 in some embodiments.

[0118] In some embodiments, the electronic device 10 may form a first sound output channel 1a, a second sound output channel 1b, and a third sound output channel 1c. The first sound output channel 1a connects the first diaphragm 311 and the first sound outlet 101, the second sound output channel 1b connects the second diaphragm 312 and the second sound outlet 102, and the third sound output channel 1c connects the third diaphragm 313 and the third sound outlet 103, so that the first speaker module 3 can output sound through the first sound outlet 101, the second sound outlet 102, and the third sound outlet 103. The structures of the first sound output channel 1a, the second sound output channel 1b, and the third sound output channel 1c can be referred to the description below.

[0119] Please refer to the following: Figure 5 and Figure 6 , Figure 5 yes Figure 2A partial structural diagram of the middle frame 11 shown. Figure 6 yes Figure 5 The diagram shows a portion of the structure of the middle frame 11 from another perspective. Figure 5 The viewpoint of the middle frame 11 shown is Figure 4 The view of the middle frame 11 after it has been flipped.

[0120] In some embodiments, the middle frame 11 may include a border 111 and a middle plate 112.

[0121] For example, the frame 111 can be arranged around the middle plate 112, and the frame 111 is fixedly connected to the middle plate 112. The frame 111 can be generally ring-shaped, and charging holes, card slots, etc. can be provided on the frame 111. The frame 111 can be made of metal. For example, the frame 111 can include a first side 1101, a second side 1102, a third side 1103, and a fourth side 1104 connected in sequence. For example, the first side 1101 and the third side 1103 are arranged opposite each other in the length direction of the middle frame 11, with the first side 1101 located on the top side and the third side 1103 located on the bottom side. The second side 1102 and the fourth side 1104 are arranged opposite each other in the width direction (i.e., the X direction) of the middle frame 11.

[0122] For example, the middle plate 112 can be generally plate-shaped, and both sides of the middle plate 112 can be used to install components and modules of the electronic device 10. The middle plate 112 can be partially hollowed out, so that the spaces on both sides of the middle plate 112 can be connected. When a module needs to cross the middle plate 112, it can cross through the hollowed-out area, thereby reducing the thickness of the electronic device 10 and facilitating the thin design of the electronic device 10.

[0123] For example, the middle plate 112 and the frame 111 can be integral structural components. In some examples, the middle plate 112 and the frame 111 can be integrally formed, but are not limited thereto. For example, the middle plate 112 and the frame 111 can have detachable parts, which can be assembled to form part of the middle plate 112 or the frame 111.

[0124] In some embodiments, the middle frame 11 may be provided with a first mounting slot 113 and a second mounting slot 114.

[0125] The first mounting groove 113 and the second mounting groove 114 can be located on opposite sides of the middle frame 11. The first mounting groove 113 is located on the side of the middle frame 11 facing away from the rear cover 12, and the second mounting groove 114 is located on the side of the middle frame 11 facing the rear cover 12.

[0126] In some embodiments, the first mounting slot 113 can be used to mount the display screen 2. The first mounting slot 113 has a relatively large space and can be surrounded by the frame 111 and the middle plate 112. It is understood that the depth and area of ​​the first mounting slot 113 can be set according to the size of the display screen 2, and this embodiment does not impose specific limitations.

[0127] In some embodiments, the second mounting slot 114 can be used to mount the first speaker module 3. The second mounting slot 114 occupies a small space and can be formed in the middle plate 112. For example, the second mounting slot 114 can be a recessed slot structure relative to the middle plate 112. In other examples, the middle plate 112 can have multiple protruding protrusions that surround a slot space, thereby forming the second mounting slot 114. The speaker module can be placed in the second mounting slot 114, and the main structure of the speaker module can be fixed to the multiple protrusions, thereby fixing the speaker module to the middle frame 11.

[0128] In some embodiments, the middle frame 11 has a first through hole 115, a second through hole 116, and a third through hole 117. The first through hole 115, the second through hole 116, and the third through hole 117 are arranged at intervals.

[0129] For example, a first through hole 115 is formed in the middle plate 112, connecting the spaces on both sides of the middle plate 112. A second through hole 116 is formed in the middle plate 112, connecting the spaces on both sides of the middle plate 112. A third through hole 117 is formed in the middle plate 112, connecting the spaces on both sides of the middle plate 112.

[0130] For example, the dimensions of the third through hole 117 and the second through hole 116 can be approximately the same. For instance, both the third through hole 117 and the second through hole 116 can be approximately rectangular. The first through hole 115 can be approximately triangular. The shapes of the first through hole 115, the second through hole 116, and the third through hole 117 can be determined according to actual conditions, and this embodiment does not impose specific limitations on this. For example, in the width direction of the middle frame 11, the third through hole 117, the second through hole 116, and the first through hole 115 can be arranged sequentially. In the length direction of the middle frame 11, the first through hole 115, the second through hole 116, and the third through hole 117 can be arranged sequentially. The arrangement of the first through hole 115, the second through hole 116, and the third through hole 117 can be determined according to actual conditions, and this embodiment does not impose specific limitations on this.

[0131] In some embodiments, the middle frame 11 has a first sound outlet groove 118, which is used to form a first sound outlet 101 (see the following description for details).

[0132] For example, the first sound outlet groove 118 can be formed by the middle plate 112 and the frame 111. For instance, the first sound outlet groove 118 can be located in the middle of a shorter side of the frame 111. For example, the first sound outlet groove 118 can communicate with the first through hole 115. The first through hole 115 can be disposed adjacent to the first sound outlet groove 118 so that the two can be easily connected directly, and the channel formed by the connection is short. The groove opening direction of the first sound outlet groove 118 can be approximately perpendicular to the middle plate 112.

[0133] In some embodiments, the second sound outlet 102 and the third sound outlet 103 are provided in the middle frame 11. The second sound outlet 102 and the third sound outlet 103 may be arranged at intervals. The second sound outlet 102 and the third sound outlet 103 are also arranged at intervals from the first sound outlet slot 118.

[0134] For example, the second sound outlet 102 may be a single outlet. For instance, the second sound outlet 102 may be racetrack-shaped, or it may be circular, elliptical, or irregularly shaped. In other examples, the second sound outlet 102 may also include multiple smaller openings.

[0135] For example, the second sound outlet 102 can be located on the side frame 111 of the middle frame 11. The second sound outlet 102 can be located on the short side of the side frame 111 that forms the first sound outlet groove 118. For example, the middle frame 11 can have a first channel 119, which can extend through the middle frame 11. The first opening of the first channel 119 is located on the side of the middle plate 112 facing away from the second mounting groove 114, and the second outlet of the first channel 119 is located on the side of the side frame 111 facing away from the middle plate 112, forming the second sound outlet 102.

[0136] For example, the third sound outlet 103 may be a single outlet. For instance, the third sound outlet 103 may be racetrack-shaped, or it may be circular, elliptical, or irregularly shaped. In other examples, the third sound outlet 103 may also include multiple smaller openings.

[0137] For example, the third sound outlet 103 can be located on the edge 111 of the middle frame 11. The third sound outlet 103 can be located on one of the long sides of the edge 111. For example, the middle frame 11 can have a second channel 1110, which can extend through the middle frame 11. The first opening of the second channel 1110 is located on the side of the middle plate 112 facing away from the second mounting groove 114, and the second outlet of the second channel 1110 is located on the side surface of the edge 111 facing away from the middle plate 112, forming the third sound outlet 103.

[0138] For example, the opening directions of the second sound outlet 102 and the third sound outlet 103 can be different. For instance, the opening direction of the first sound outlet 101 can be parallel to the thickness direction of the middle frame 11. The opening direction of the second sound outlet 102 can be parallel to the length direction of the middle frame 11. The opening direction of the third sound outlet 103 can be parallel to the length direction of the middle frame 11. The opening directions of the second sound outlet 102 and the third sound outlet 103 can be approximately perpendicular. It is understood that the opening directions of the second sound outlet 102 and the third sound outlet 103 can be adjusted according to the shape of the middle frame 11.

[0139] In some embodiments, the middle frame 11 may also have a first connecting groove 1111, a second connecting groove 1112, and a third connecting groove 1113. The first connecting groove 1111, the second connecting groove 1112, and the third connecting groove 1113 are arranged at intervals.

[0140] For example, the first connecting groove 1111 is formed on the side surface of the middle plate 112 facing away from the second mounting groove 114. The first connecting groove 1111 can be arranged with the first through hole 115 in the thickness direction of the middle frame 11.

[0141] For example, the second connecting groove 1112 is formed on the side surface of the middle plate 112 facing away from the second mounting groove 114, and the second connecting groove 1112 is recessed into the surface of the middle plate 112. One end of the second connecting groove 1112 is connected to the second through hole 116, and the other end is connected to the first channel 119.

[0142] For example, the third connecting groove 1113 is formed on the side surface of the middle plate 112 facing away from the second mounting groove 114, and the third connecting groove 1113 is recessed into the surface of the middle plate 112. One end of the third connecting groove 1113 is connected to the third through hole 117, and the other end is connected to the second channel 1110.

[0143] Please see Figure 7 , Figure 7 yes Figure 2 The display screen 2 shown is a structural schematic diagram in some embodiments.

[0144] In some embodiments, the display screen 2 may include an adhesive backing 21 and a display module 22, wherein the adhesive backing 21 may be fixed to the display module 22. The adhesive backing 21 has a first slot 211, a second slot 212, and a third slot 213. The first slot 211, the second slot 212, and the third slot 213 are spaced apart.

[0145] For example, the adhesive backing 21 can be a single piece of adhesive material. The adhesive backing 21 can also comprise multiple pieces of adhesive material.

[0146] For example, the first slot 211, the second slot 212 and the third slot 213 are recessed relative to the surface of the adhesive 21.

[0147] Please refer to the following: Figures 8 to 10 , Figure 8 It is part of the structure of electronic device 10 along Figure 4 A sectional view cut at point AA. Figure 9 It is part of the structure of electronic device 10 along Figure 4 A sectional view cut at point BB. Figure 10 It is part of the structure of electronic device 10 along Figure 4 A sectional view cut at point CC.

[0148] In some embodiments, the display screen 2 may be mounted on the middle frame 11.

[0149] For example, the display screen 2 can be located in the first mounting slot 113, and most of the structure of the display screen 2 can contact and be fixedly connected to the middle frame 11, thereby fixing the display screen 2 in the first mounting slot 113 of the middle frame 11. For example, the display screen 2 can be fixedly connected to the middle frame 11 by adhesive 21.

[0150] For example, the display screen 2 can be sealed to the middle frame 11 and cover the first connecting groove 1111, the second connecting groove 1112 and the third connecting groove 1113. The first connecting groove 1111, the second connecting groove 1112 and the third connecting groove 1113 are all opened on the side of the middle frame 11 facing the display screen 2.

[0151] Please see Figure 8 In some embodiments, the display screen 2 can further enclose the first connecting groove 1111 and form a first sound outlet channel 1a. Specifically, the portion of the display screen 2 opposite to the first connecting groove 1111 can enclose the first connecting groove 1111 to form a channel; a portion of the structure of the display screen 2 is disposed opposite to the first sound outlet groove 118 and has a gap between it and the sound outlet groove 105, thereby enclosing and forming a first sound outlet 101. Thus, by enclosing the first connecting groove 1111 and the first sound outlet groove 118 by the display screen 2, a first sound outlet channel 1a from the first through hole 115 to the first sound outlet 101 is formed. The sidewalls of the first sound outlet channel 1a can be relatively sealed to allow sound to propagate from the first through hole 115 to the first sound outlet 101. For example, adhesive 21 can surround the first connecting groove 1111 and the adhesive 21 seals the connection to the middle frame 11.

[0152] For example, the height of the first sound output channel 1a in the thickness direction of the electronic device can be greater than 0.3 mm. The minimum cross-sectional area of ​​the first sound output channel 1a can be greater than 4.5 square millimeters.

[0153] In this embodiment, the first sound output channel 1a is formed by the middle frame 11 and the display screen 2. The main space of the first sound output channel 1a can be easily formed directly in the middle frame 11 by slotting and drilling (i.e., the first through hole 115, the first connecting groove 1111, and the first sound output groove 118), without the need to set up additional structural components to separately form the first sound output channel 1a, which helps to simplify the structure of the housing assembly 1 and the electronic device 10.

[0154] In this embodiment, the first sound outlet 101 is located between the frame 111 and the display screen 2, and is situated on the top side of the display screen 2; the second sound outlet 102 and the third sound outlet 103 are both located on the frame 111, with the second sound outlet 102 located on the first side 1101 of the frame 111 and the third sound outlet 103 located on the second side 1102 of the frame 111. At this time, the first side 1101 is located on the top side of the display screen 2. In this embodiment, the second sound outlet 102 and the third sound outlet 103 are both located on the frame 111. The second sound outlet 102 and the third sound outlet 103 are easily formed in the same or similar manner, and the channels from the second diaphragm 312 to the second sound outlet 102 and from the third diaphragm 313 to the second sound outlet 102 are also easily formed in similar manner, thereby simplifying the sound output structure of the electronic device 10. Furthermore, the second sound outlet 102 and the third sound outlet 103 are respectively located on two connected sides of the middle frame, resulting in better noise reduction. For example, this can achieve 35 dB of noise reduction. In some other embodiments, when both the second sound outlet 102 and the third sound outlet 103 are located on the top side, i.e., on the first side 1101, only 24 dB of noise reduction can be achieved.

[0155] In some embodiments, since the adhesive 21 may have a first groove 211, it is beneficial to increase the cross-sectional area of ​​the channel corresponding to the first connecting groove 1111 in the first sound output channel 1a, which is beneficial to improve the sound propagation effect.

[0156] Please see Figure 9 In some embodiments, the display screen 2 can further enclose the second through hole 116 and together with the first channel 119, form a second sound outlet channel 1b. Specifically, the portion of the display screen 2 opposite to the second connecting groove 1112 can enclose the second connecting groove 1112 to form a channel. Thus, by enclosing the second connecting groove 1112 with the display screen 2, a second sound outlet channel 1b is formed from the second through hole 116 to the second sound outlet 102. The sidewalls of the second sound outlet channel 1b can be relatively sealed to allow sound to propagate from the second through hole 116 to the second sound outlet 102. For example, adhesive 21 can surround the second connecting groove 1112 and seal the connection to the frame 11.

[0157] In this embodiment, the second sound output channel 1b is formed by the middle frame 11 and the display screen 2. The main space of the second sound output channel 1b can be easily formed directly in the middle frame 11 by slotting and drilling (i.e., the second through hole 116, the second connecting channel, and the first channel 119), without the need to set up additional structural components to separately form the second sound output channel 1b, which helps to simplify the structure of the middle frame 11 and the electronic device 10.

[0158] In some embodiments, since the adhesive backing 21 can have a second groove 212, it is beneficial to increase the cross-sectional area of ​​the channel corresponding to the second connecting groove 1112 in the second sound output channel 1b, which is beneficial to improve the sound propagation effect.

[0159] Please see Figure 10 In some embodiments, the display screen 2 can further enclose the third through-hole 117 and together with the second channel 1110, form a third sound outlet channel 1c. Specifically, the portion of the display screen 2 opposite to the third connecting groove 1113 can enclose the third connecting groove 1113 to form a channel. Thus, by enclosing the third connecting groove 1113 with the display screen 2, a third sound outlet channel 1c is formed from the third through-hole 117 to the third sound outlet 103. The sidewalls of the third sound outlet channel 1c can be relatively sealed to allow sound to propagate from the third through-hole 117 to the third sound outlet 103. For example, adhesive 21 can surround the third connecting groove 1113 and seal the connection to the frame 11.

[0160] In this embodiment, the third sound output channel 1c is surrounded by the middle frame 11 and the display screen 2. The main space of the third sound output channel 1c can be easily formed directly in the middle frame 11 by slotting and drilling (i.e., the third through hole 117, the third connecting channel, and the second channel 1110), without the need to set up additional structural components to separately surround the third sound output channel 1c, which helps to simplify the structure of the middle frame 11 and the electronic device 10.

[0161] In some embodiments, since the adhesive backing 21 may have a third groove 213, it is beneficial to increase the cross-sectional area of ​​the channel corresponding to the third connecting groove 1113 in the third sound output channel 1c, which is beneficial to improve the sound propagation effect.

[0162] In some embodiments, the first sound output channel 1a, the second sound output channel 1b, and the third sound output channel 1c are all enclosed by the middle frame 11 and the display screen 2. In this case, the display screen 2 and the middle frame 11 can directly form three independent sound output channels, reducing the number of components in the electronic device 10 and the space occupied by forming the three sound output channels, making the structure of the electronic device 10 more reasonable, and thus facilitating the thinner design of the electronic device 10. In addition, since there is no need for a bracket or other structure to enclose the three sound output channels, there is no pressure from the bracket or other structure on the middle frame 11, making the stress on the middle frame 11 more reasonable, making it easier to keep the middle frame 11 flat, and providing better support for the display screen 2.

[0163] When the first connecting groove 1111, the second connecting groove 1112, and the third connecting groove 1113 are respectively applied to form the first sound output channel 1a, the second sound output channel 1b, and the third sound output channel 1c, the first connecting groove 1111, the second connecting groove 1112, and the third connecting groove 1113 are all opened on the same side of the middle frame 11, which facilitates the manufacturing and processing of the middle frame 11, and also facilitates the first connecting groove 1111, the second connecting groove 1112, and the third connecting groove 1113 to directly form the corresponding sound output channels with the display screen 2, making the assembly of the electronic device 10 relatively simple.

[0164] In some other embodiments, the housing assembly 1 also includes a bracket (not shown), which is fixedly connected to the middle frame 11 and forms a second sound outlet channel 1b or a third sound outlet channel 1c. In this case, by having the bracket cooperate with the middle frame 11 to form the second sound outlet channel 1b or the third sound outlet channel 1c, it is beneficial to set the shape of the channel according to the sound output requirements and reduce the restriction of the middle frame 11 on the shape of the second sound outlet channel 1b and the third sound outlet channel 1c.

[0165] In some other embodiments, the housing assembly 1 also includes a bracket (not shown), which is fixedly connected to the rear cover 12 and forms a second sound outlet channel 1b or a third sound outlet channel 1c. In this case, by using the bracket in conjunction with the rear cover 12 to form the second sound outlet channel 1b or the third sound outlet channel 1c, it is beneficial to set the shape of the channel according to the sound output requirements and reduce the restriction of the middle frame 11 on the shape of the second sound outlet channel 1b and the third sound outlet channel 1c.

[0166] Please refer to the following: Figure 11 and Figure 12 , Figure 11 yes Figure 2 A schematic diagram of the structure of the first speaker module 3 in some embodiments. Figure 12 yes Figure 11 The diagram shown is an exploded view of the first speaker module 3 in some embodiments.

[0167] In some embodiments, the first speaker module 3 may include a core 31 and a housing 32, with the core 31 and the housing 32 fixedly connected.

[0168] In some embodiments, the core 31 may include a frame, a diaphragm, a magnetic circuit assembly, and a voice coil. The first speaker module 3 is described below as an example.

[0169] For example, the basket frame can be a cover structure or a frame structure. The basket frame is used to support the diaphragm, voice coil, and magnetic circuit components, which can be directly or indirectly mounted on the basket frame.

[0170] For example, the magnetic circuit assembly can be fixed to the basin frame, the magnetic circuit assembly can have a magnetic gap, and the magnetic circuit assembly can be formed by splicing or combining multiple magnets.

[0171] For example, the diaphragm can be fixed to the frame, and the diaphragm can be positioned opposite the magnetic circuit assembly. The diaphragm can be deformable to vibrate and produce sound. The diaphragm can be a thin film structure.

[0172] For example, one end of the voice coil can be fixed to the diaphragm, and the other end can be located in the magnetic gap of the magnetic circuit assembly. When the voice coil is energized, the voice coil and the magnetic circuit assembly generate an interaction force, and the voice coil is driven. Since the voice coil is fixedly connected to the diaphragm, the voice coil drives the diaphragm to vibrate, thereby producing sound.

[0173] In some embodiments, the outer shell 32 may be fitted over the outer side of the core 31. The outer shell 32 may include a bottom shell 321 and a top shell 322. The outer shell 32 and the core 31 may enclose a first cavity, a second cavity, and a third cavity. The first cavity provides sound for the first diaphragm 311, the second cavity provides sound for the second diaphragm 312, and the third cavity provides sound for the third diaphragm 313. The first, second, and third cavities may be independent of each other and not interconnected. The outer shell 32 may be provided with a first sound outlet 323, a second sound outlet 324, and a third sound outlet 325. The first sound outlet 323 connects the first cavity and the outer space of the outer shell 32, the second sound outlet 324 connects the second cavity and the outer space of the outer shell 32, and the third sound outlet 325 connects the third cavity and the outer space of the outer shell 32. The first, second, and third sound outlets 323, 324, and 325 face the same side of the first speaker module 3.

[0174] In some implementations, the core 31 may include multiple diaphragms.

[0175] For example, multiple diaphragms may be located in a core 31, with the multiple diaphragms exposed in the first speaker module 3. In this case, the first speaker module 3 includes a core 31.

[0176] For example, the first speaker module 3 may include three diaphragms: a first diaphragm 311, a second diaphragm 312, and a third diaphragm 313. The second diaphragm 312 and the third diaphragm 313 are arranged side-by-side, each facing away from the first diaphragm 311. In other words, the first diaphragm 311 is located on one side of the first speaker module 3, and the second diaphragm 312 and the third diaphragm 313 are located on the other opposite side of the first speaker module 3. For example, the second diaphragm 312 and the third diaphragm 313 may be approximately the same size. For example, each diaphragm can operate independently to achieve independent sound production.

[0177] For example, the second diaphragm 312 may face the second sound outlet 324. The third diaphragm 313 may face the third sound outlet 325.

[0178] For example, the first speaker module 3 can be roughly rectangular cube structure, and the first diaphragm 311, the second diaphragm 312 and the third diaphragm 313 can each be roughly rectangular structure, which is beneficial for setting diaphragms with larger areas.

[0179] For example, the area of ​​the first diaphragm 311 is larger than the areas of the second diaphragm 312 and the third diaphragm 313. In this case, with a certain volume of the first speaker module 3, the area of ​​the first diaphragm 311 is easier to set to be larger, the sound emitted by the first diaphragm 311 is louder and the sound quality is higher, and the second diaphragm 312 and the third diaphragm 313 are also easier to set to be larger, which is beneficial to improving the sound quality of the first speaker module 3.

[0180] For example, the first diaphragm 311 can produce sound through the first sound outlet 323. At this time, the sound produced by the vibration of the first diaphragm 311 can be transmitted through the first cavity to the first sound outlet 323, and then transmitted from the first sound outlet 323 to the outside of the first speaker module 3.

[0181] In some other embodiments, the first speaker module 3 may include a plurality of cores 31, with a first diaphragm 311, a second diaphragm 312, and a third diaphragm 313 located on the plurality of cores 31. For example, each core 31 may have a corresponding diaphragm.

[0182] Please refer to the diagram and consult the reference materials. Figures 13 to 14 , Figure 13 It is an electronic device 10-line Figure 4 A sectional view cut at point AA. Figure 14 It is an electronic device 10-line Figure 4 A sectional view cut at point BB. Figure 15 It is an electronic device 10 is along Figure 4 A sectional view cut at point CC.

[0183] In some embodiments, the first speaker module 3 may be mounted on the middle frame 11.

[0184] For example, the first speaker module 3 can be fixed to the side of the middle frame 11 facing away from the display screen 2 by fasteners. The first speaker module 3 can be located in the second mounting groove 114. There can be multiple fasteners, and the fasteners can be screws, clips, etc. For example, the first speaker module 3 can be fixed to the middle frame 11 by adhesive bonding, such as using adhesive backing, foam adhesive, or spot adhesive.

[0185] For example, such as Figure 13 The first sound outlet 323 of the first speaker module 3 is connected to the first through hole 115, so that the first diaphragm 311 of the first speaker module 3 emits sound through the first sound outlet channel 1a.

[0186] For example, such as Figure 14 The second sound outlet 324 of the first speaker module 3 aligns with the second through hole 116, allowing the second diaphragm 312 of the first speaker module 3 to emit sound through the second sound outlet channel 1b. For example, the second diaphragm 312 can face the second through hole 116 and be directly opposite it. This "directly opposite" arrangement can mean that their projections in the arrangement direction overlap. Exemplarily, the first speaker module 3 can be sealed to the middle frame 11, forming a space between the second diaphragm 312 and the middle frame 11 that only connects to the second through hole 116, thus allowing the second diaphragm 312 to emit sound only through the second sound outlet channel 1b. It is understood that the space between the second diaphragm 312 and the middle frame 11, as well as the second sound outlet channel 1b, can constitute the front acoustic cavity of the second diaphragm 312.

[0187] For example, such as Figure 15 The third sound outlet 325 of the first speaker module 3 is aligned with the third through hole 117, allowing the third diaphragm 313 of the first speaker module 3 to emit sound through the third sound outlet channel 1c. For example, the third diaphragm 313 can face the third through hole 117 and be directly opposite it. Exemplarily, the first speaker module 3 can be sealed to the middle frame 11, forming a space between the third diaphragm 313 and the middle frame 11 that only communicates with the third through hole 117, thereby allowing the third diaphragm 313 to emit sound only through the third sound outlet channel 1c. It is understood that the space between the third diaphragm 313 and the middle frame 11, as well as the third sound outlet channel 1c, can constitute the front acoustic cavity of the third diaphragm 313.

[0188] For example, in the thickness direction of the middle frame 11, the projection of the first through hole 115 covers more than 50% of the area of ​​the projection of the first sound outlet 323; the projection of the second through hole 116 covers more than 50% of the area of ​​the projection of the second sound outlet 324; and the projection of the third through hole 117 covers more than 50% of the area of ​​the projection of the third sound outlet 325. For example, the distance between the plate surface of the middle frame 11 and the sidewall of the second through hole 116 can be greater than 0.4 mm, but is not limited to this.

[0189] Understandably, the first diaphragm 311 and the second diaphragm 312 both face the surface of the middle frame 11, while the first sound outlet 323, the second sound outlet 324, and the third sound outlet 325 also face the surface of the middle frame 11. Since the orientation of the first diaphragm 311 is opposite to that of the second diaphragm 312, the arrangement of the first cavity and the first sound outlet 323 guides and changes the direction of sound propagation after the first diaphragm 311 vibrates and produces sound.

[0190] In this embodiment, since the first sound outlet 323, the second diaphragm 312, and the third diaphragm 313 all face the surface of the middle frame (i.e., the middle plate 112), and the first sound outlet 323, the second sound outlet 324, and the third sound outlet 325 have the same orientation, and all emit sound towards the surface of the middle frame 11 in the first speaker module 3, the first speaker module 3 can easily form a space directly with the middle frame 11 through its own structure, thereby connecting the first diaphragm 311 with the first sound outlet channel 1a, the second diaphragm 312 with the second sound outlet channel 1b, and the third diaphragm 313 with the third sound outlet channel 1c. No other components are needed to form the front sound cavity, thus reducing the number of components in the electronic device 10.

[0191] In this embodiment, the second diaphragm 312 and the third diaphragm 313 face the plate surface of the middle frame 11, and the orientation of the first diaphragm 311 is opposite to that of the second diaphragm 312. Therefore, for the second diaphragm 312 and the third diaphragm 313, the second diaphragm 312 and the third diaphragm 313 directly face the plate surface of the middle frame 11 (i.e., the middle plate 112), eliminating the need for an additional turning cavity structure in the first speaker module 3 to guide and change the propagation direction of the sound emitted by the second diaphragm 312 and the third diaphragm 313. This simplifies the structure of the first speaker module 3 and reduces the width occupied by the cavity structure used for sound transmission, which is beneficial for further miniaturization of the first speaker module 3 and reduces the space occupied in the electronic device.

[0192] In some other embodiments, the first diaphragm 311 may face the display screen 2, and the second diaphragm 312 and the third diaphragm 313 may face the back cover 12.

[0193] In some implementations, such as Figures 13 to 15The first speaker module 3 includes a core 31, and the first diaphragm 311, the second diaphragm 312, and the third diaphragm 313 are located in the same core 31. In this embodiment, when multiple diaphragms are located in one core 31, it is beneficial to reuse multiple support structures, magnetic circuit structures, etc., thereby greatly reducing the volume of the first speaker module 3, which is beneficial for further application in miniaturized and thin electronic devices 10.

[0194] Please refer to the following: Figures 16 to 18 , Figure 16 This is a schematic diagram of the sound output path used for sound output from the first diaphragm 311. Figure 17 This is a schematic diagram of the sound output path used for sound output from the second diaphragm 312. Figure 18 This is a schematic diagram of the sound output path used for sound output from the third diaphragm 313. Among them, Figures 16 to 18 The sound output path shown is actually a cavity space enclosed by a solid component in the electronic device 10. To make it easier to show the shape of the sound output path, the sound output path is directly shown as a line.

[0195] Please see Figure 16 In some embodiments, the sound output path from the first diaphragm 311 to the first sound outlet 101 is the front sound cavity of the first diaphragm 311. The front sound cavity of the first diaphragm 311 may include a first part 2a and a second part 2b, with the first part 2a connected to the second part 2b.

[0196] For example, the first part 2a may be enclosed by the interior of the first speaker module 3. The second part 2b may be enclosed by the middle frame 11 and the display screen 2, and the second part 2b is also the first sound output channel 1a.

[0197] The boundary between the first part 2a and the second part 2b is approximately at the position of the first sound outlet 323 or the first through hole 115.

[0198] For example, when the first sound outlet 101 is a micro-slit surrounded by the screen and the mid-frame 11 (see reference) Figure 8 The first sound outlet 101 has a long and narrow opening shape. At this time, the first sound outlet 101 can have a longer length to increase the area of ​​the first sound outlet 101.

[0199] For example, the minimum cross-sectional area of ​​the front acoustic cavity of the first diaphragm 311 can be greater than 3 square millimeters. For instance, the minimum cross-sectional area of ​​the first sound outlet channel 1a can be greater than 3 square millimeters. In this case, the airflow resistance of the first sound outlet channel 1a is small, and the sound propagation has less noise, thereby enabling the electronic device 10 to have better sound quality.

[0200] It is understandable that the front acoustic cavity of the first diaphragm 311 is a cavity space that passes through the middle frame 11. The front acoustic cavity of the first diaphragm 311 crosses both sides of the middle plate 112 of the middle frame 11 from the first through hole 115 (see reference). Figure 8 ).

[0201] Please see Figure 17 In some embodiments, the sound path from the second diaphragm 312 to the second sound outlet 102 is the front sound cavity of the second diaphragm 312. The front sound cavity of the second diaphragm 312 may include a first part 3a, a second part 3b and a third part 3c, with the second part 3b connecting the first part 3a and the third part 3c.

[0202] For example, the first part 3a may be enclosed by the first speaker module 3 and the middle frame 11. The second part 3b may be enclosed by the middle frame 11 and the display screen 2, and the second part 3b corresponds to the second connecting groove 1112. The third part 3c may be a channel opened inside the middle frame 11, that is, the third part 3c is the first channel 119 (see reference). Figure 9 The second part 3b and the third part 3c constitute the second sound output channel 1b.

[0203] The boundary between the first part 3a and the second part 3b is approximately the location of the second through hole 116.

[0204] For example, the minimum cross-sectional area of ​​the front acoustic cavity of the second diaphragm 312 can be greater than 3 square millimeters. For instance, the minimum cross-sectional area of ​​the second sound outlet channel 1b can be greater than 3 square millimeters to reduce airflow resistance in the second sound outlet channel 1b, resulting in less noise during sound propagation and thus better sound quality for the electronic device 10.

[0205] It is understandable that the front acoustic cavity of the second diaphragm 312 is a space that passes through the middle frame 11. The front acoustic cavity of the second diaphragm 312 crosses both sides of the middle plate 112 of the middle frame 11 through the second through hole 116 (see reference). Figure 9 ).

[0206] Please see Figure 18 In some embodiments, the sound path from the third diaphragm 313 to the third sound outlet 103 is the front sound cavity of the third diaphragm 313. The front sound cavity of the third diaphragm 313 may include a first part 4a, a second part 4b and a third part 4c, with the second part 4b connecting the first part 4a and the third part 4c.

[0207] For example, the first part 4a may be enclosed by the first speaker module 3 and the middle frame 11. The second part 4b may be enclosed by the middle frame 11 and the display screen 2, and the second part 4b corresponds to the third connecting slot 1113. The third part 4c may be a channel opened inside the middle frame 11, that is, the third part 4c is the second channel 1110 (see also...). Figure 10 The second part 4b and the third part 4c constitute the third sound output channel 1c (see reference). Figure 10 ).

[0208] The boundary between the first part 4a and the second part 4b is approximately the location of the third through hole 117.

[0209] For example, the minimum cross-sectional area of ​​the front acoustic cavity of the third diaphragm 313 can be greater than 3 square millimeters. For instance, the minimum cross-sectional area of ​​the third sound outlet channel 1c can be greater than 3 square millimeters to reduce airflow resistance in the third sound outlet channel 1c, resulting in less noise during sound propagation and thus better sound quality for the electronic device 10.

[0210] It is understandable that the front acoustic chamber of the third diaphragm 313 is a space that passes through the middle frame 11. The front acoustic chamber of the third diaphragm 313 crosses both sides of the middle plate 112 of the middle frame 11 through the second through hole 116 (see reference). Figure 10 ).

[0211] Please refer to the following: Figure 19 and Figure 20 , Figure 19 yes Figure 1 The partial structure of the electronic device 10 shown is illustrated in structural diagrams of other embodiments. Figure 20 yes Figure 19 This is a schematic diagram of the internal structure of a portion of the electronic device 10 shown. Wherein, Figure 19 The electronic device 10 shown in the embodiment may include Figure 4 Most of the technical features of the electronic device 10 shown in the embodiment will not be repeated for the same technical features; the following mainly describes the differences between the two. Among them, the middle frame 11 and the first speaker module 3 are only shown in terms of the structure related to the sound output channel.

[0212] Figure 19 The electronic device 10 shown in the embodiment and Figure 4 The main difference of the electronic device 10 shown in the embodiment lies in the way the sound output channel is arranged. In some embodiments, the housing assembly 1 may also include a bracket 13, which is used to form a sound output channel with the housing assembly 1 to form a first diaphragm 311, a second diaphragm 312, or a third diaphragm 313.

[0213] In some embodiments, the bracket 13 is used to form a first sound outlet channel 1a of the first diaphragm 311 with the middle frame 11.

[0214] For example, the middle frame 11 has a third channel 1114, one end of the third channel 1114 forms a first opening 1115, and the other end forms a second opening 1116. The first opening 1115 is used to form a first sound outlet 101.

[0215] For example, the bracket 13 has a fourth through hole 131. The bracket 13 is installed on the middle frame 11 and blocks the second opening 1116, thereby forming a channel from the fourth through hole 131 to the first opening 1115, that is, the first sound outlet channel 1a.

[0216] For example, the bracket 13 can be fixedly connected to the middle frame 11. Furthermore, the bracket 13 and the middle frame 11 can be sealed together by a sealing ring.

[0217] The first sound outlet 323 of the first speaker module 3 is connected to the fourth through hole 131, and the two can be sealed together, so that the internal cavity of the first speaker module 3 is connected to the first sound outlet channel 1a, and the vibration of the first diaphragm 311 can produce sound through the first sound outlet channel 1a.

[0218] In some other embodiments, the second and third sound output channels can be arranged in a similar manner, that is, by the middle frame 11 and the bracket 13, which will not be described in detail in this embodiment.

[0219] Please refer to the following: Figure 21 and Figure 22 , Figure 21 yes Figure 1 The partial structure of the electronic device 10 shown is illustrated in structural diagrams of some other embodiments. Figure 22 yes Figure 21 This is a schematic diagram of the internal structure of a portion of the electronic device 10 shown. Wherein, Figure 21 The electronic device 10 shown in the embodiment may include Figure 4 Most of the technical features of the electronic device 10 shown in the embodiment will not be repeated for the same technical features. The following mainly describes the differences between the two.

[0220] Figure 22 The electronic device 10 shown in the embodiment and Figure 4 The main difference in the electronic device 10 shown in the embodiments lies in the arrangement of the sound output channel. In some embodiments, the bracket 13 is used to form a third sound output channel 1c of the third diaphragm 313 together with the rear cover 12.

[0221] For example, the back cover 12 has a fifth through hole 121, which can be used to form a third sound outlet. For example, the bracket 13 can be fixedly connected to the first speaker module 3 and the back cover 12, and is sealed to the first speaker module 3 and the back cover 12. For example, the bracket 13 can be provided with a first pair of interfaces and a second pair of interfaces. The first pair of interfaces can mate with the first speaker module 3, and the second pair of interfaces can be directly opposite the fifth through hole 121, thereby forming a third sound outlet channel 1c. The sound emitted by the first speaker module 3 enters the third sound outlet channel 1c through the first pair of interfaces, and is propagated to the outside of the electronic device 10 through the second pair of interfaces and the fifth through hole 121 (third sound outlet 103).

[0222] In some other embodiments, the housing assembly 1 may not include the bracket 13, and the third sound outlet channel 1c is formed by the first speaker module 3 and the rear cover 12.

[0223] In some other embodiments, the first and second sound channels can also be arranged in a similar manner, that is, by the rear cover 12 and the bracket 13, which will not be described in detail in this embodiment.

[0224] In some embodiments, housing assembly 1 may include a dustproof component. For example, the dustproof component may be a dustproof mesh. The dustproof component may be securely connected to the rear cover 12 and block the third sound outlet 103, thereby preventing dust and other external contaminants from entering the electronic device 10.

[0225] In some embodiments of this application, the first diaphragm of the first speaker module may face the display screen, while the second and third diaphragms may face the rear cover. A first sound outlet is formed by the mid-frame and the display screen, a second sound outlet is formed by the mid-frame and a bracket, and a third sound outlet is formed by the rear cover and a bracket.
