Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and in particular to a sound output structure and electronic equipment. Background Technology

[0002] Electronic devices are typically equipped with sound output structures, and some electronic devices have folding functions. When folded, users have various ways of holding the device, resulting in different needs for the sound output structure. Related technologies are difficult to meet the diverse needs of users. Utility Model Content

[0003] To overcome the problems existing in related technologies, this disclosure provides a sound output structure and an electronic device.

[0004] In a first aspect, the sound-emitting structure provided according to the embodiments of this disclosure includes a first base component and a second base component. The first base component is provided with a first sound outlet, a second sound outlet, and a receiving space. The receiving space is used to accommodate a sound-emitting device. The first sound outlet and the second sound outlet are respectively connected to the receiving space. The opening of the first sound outlet and the opening of the second sound outlet are located on different surfaces of the first base component. The opening of the first sound outlet is located on the first surface of the first base component. The second base component is provided with a third sound outlet. The third sound outlet is provided with openings corresponding to different surfaces of the second base component, and at least one opening of the third sound outlet is located on the second surface of the second base component. The second base component is movably connected to the first base component. When the first base component and the second base component are switched to a folded state, the first surface and the second surface are arranged opposite to each other, and the first sound outlet and the third sound outlet are connected.

[0005] In this embodiment of the technical solution, the accommodating space of the first base component is used to accommodate a sound-producing device. The sound-producing device is capable of generating sound. The first sound outlet and the second sound outlet of the first base component are respectively connected to the accommodating space. The sound generated by the sound-producing device can be transmitted out of the first base component through the first sound outlet and the second sound outlet for the user to hear. The openings of the first sound outlet and the second sound outlet are located on different surfaces of the first base component, meaning the first base component can emit sound from multiple directions. Furthermore, the second base component is provided with a third sound outlet, and the third sound outlet has openings corresponding to different surfaces of the second base component. The first base component and the second base component are movably connected. When the first base component and the second base component are switched to a folded state, the first surface of the first base component and the second surface of the second base component are positioned opposite each other, so that the opening of the third sound outlet on the second surface connects to the first sound outlet. The sound emitted by the sound-producing device can be transmitted through the first sound outlet to the third sound outlet, and then transmitted out of the second base component through the openings of the third sound outlet on other surfaces. In the open state, sound is emitted from multiple directions through the first and second sound outlets. In the folded state, sound is emitted from multiple directions through the second and third sound outlets, satisfying diverse user needs. Furthermore, the fact that the sound-emitting device only needs to be placed within the first base component simplifies the structure. Compared to related technologies where the sound-emitting structure fails to meet diverse user needs, the sound-emitting structure of this embodiment can achieve sound emission from multiple directions in both the folded and open states, exhibiting better adaptability to various scenarios.

[0006] In some embodiments, the first substrate component further includes a third surface, and the opening of the second sound hole is located on the third surface; the second substrate component further includes a fourth surface, and at least one opening of the third sound hole is disposed on the fourth surface.

[0007] In the technical solution of this embodiment, the third surface of the first base component is disposed opposite to the first surface, and the opening of the second sound hole is disposed on the third surface. In the non-folded state, the second sound hole and the first sound hole can emit sound in opposite directions. The fourth surface of the second base component is disposed opposite to the second surface. In the folded state, the third sound hole and the second sound hole can emit sound in opposite directions to meet the sound emission needs of users with different grip directions.

[0008] In some embodiments, the first base assembly further includes a first connector, the opening of the first sound outlet is disposed on the first connector, the second base assembly further includes a second connector, and a portion of the opening of the third sound outlet is disposed on the second connector; when the first base assembly and the second base assembly are switched to a folded state, the first connector and the second connector are sealed together to connect the first sound outlet and the third sound outlet.

[0009] The technical solution of this disclosure embodiment provides a first connector and a second connector. The opening of the first sound outlet is located on the first connector, and the opening of the third sound outlet is located on the second connector. The first connector and the second connector are sealed together, thereby connecting the first sound outlet and the third sound outlet. The sealed connection also helps to reduce the distortion and attenuation of sound during transmission, so as to improve the sound output effect of the third sound outlet.

[0010] In some embodiments, the first connector is provided with a sealing groove surrounding the opening of the first sound outlet; the second connector is provided with a sealing protrusion surrounding the opening of the third sound outlet; the sealing protrusion extends into the sealing groove to seal the first connector and the second connector together.

[0011] In the technical solution of this disclosure embodiment, the first connector and the second connector have a large contact area through the cooperation of the sealing protrusion and the sealing groove, and the contact surface of the two has a relatively complex structure, which helps to improve the sealing effect and thus improve the sound output effect of the third sound hole.

[0012] In some embodiments, the inner wall of the sealing groove is provided with an elastic protrusion that abuts against the outer wall of the sealing protrusion; and / or, the outer wall of the sealing protrusion is provided with an elastic protrusion that abuts against the inner wall of the sealing groove; wherein the elastic protrusion elastically deforms at least along the abutting direction of the sealing protrusion and the sealing groove.

[0013] In the technical solution of this disclosure embodiment, an elastic protrusion is provided between the inner wall of the sealing groove and the outer wall of the sealing protrusion. The elastic protrusion can be elastically deformed, and the elastic deformation of the elastic protrusion can adapt to the wall structure of the corresponding sealing groove or sealing protrusion, thereby improving the sealing effect.

[0014] In some embodiments, the sound-emitting structure further includes a decorative element; the first base assembly includes a first functional element, at least a portion of the first connector is embedded in the first functional element, the decorative element is disposed between the first functional element and the first connector, and the surface of the decorative element smoothly transitions relative to the surfaces of the first functional element and the first connector; and / or, the second base assembly includes a second functional element, at least a portion of the second connector is embedded in the second functional element, the decorative element is disposed between the second functional element and the second connector, and the surface of the decorative element smoothly transitions relative to the surfaces of the second functional element and the second connector.

[0015] The technical solution of this disclosure embodiment includes a decorative element disposed between the first functional component and the first connecting component. The surface of the decorative element smoothly transitions relative to the surfaces of the first functional component and the first connecting component to compensate for the step difference between them, thereby improving the surface smoothness of the first base component, which helps reduce wear, enhances the grip, and improves aesthetics. Similarly, the decorative element can be disposed between the second functional component and the second connecting component, with its surface smoothly transitioning relative to the surfaces of both components to compensate for the step difference between them, thereby improving the surface smoothness of the second base component, which also helps reduce wear, enhances the grip, and improves aesthetics.

[0016] In some embodiments, the sound-emitting structure further includes an isolation structure disposed in the receiving space, the isolation structure being connected to the sound-emitting device and sealing the receiving space into a first chamber and a second chamber, the first sound outlet being connected to the first chamber and the second sound outlet being connected to the second chamber.

[0017] The technical solution of this disclosure embodiment sets up an isolation structure to isolate the accommodating space into a first chamber and a second chamber. The first chamber is connected to the first sound outlet, and the second chamber is connected to the second sound outlet. This helps to reduce the interference between the first sound outlet and the second sound outlet, thereby optimizing the sound output effect.

[0018] Secondly, the electronic device provided according to the embodiments of the present disclosure includes a sound-producing device and a sound-emitting structure of the embodiments of the present disclosure. The first base component and the second base component switch between a folded state and an unfolded state. In the unfolded state, the extension surface of the first surface overlaps with the extension surface of the second surface. The sound-producing device is disposed in the accommodating space of the first base component and is used to produce sound.

[0019] The technical solution of this disclosure embodiment includes an electronic device with a sound output structure. The sound output structure can output sound from multiple directions in both folded and folded states, which has good scene adaptability. Furthermore, the first sound output hole, the second sound output hole, and the third sound output hole share a single sound output structure, which helps to simplify the structure and also helps to ensure the consistency of sound output quality.

[0020] In some embodiments, the electronic device further includes a first screen located on a first surface and a second surface; the second substrate assembly further includes a second connector, a third sound outlet disposed on the second connector, the second connector being an elastic member, and the first screen extending to the position of the second connector; in a folded state, the second connector is capable of applying an elastic force to the first screen, and the second connector elastically deforms at least along the relative arrangement direction of the first surface and the second surface.

[0021] In the technical solution of this disclosure embodiment, since the second connector is an elastic member, the first screen can extend to the position of the second connector. Under external impact, the second connector can elastically deform at least along the relative arrangement direction of the first surface and the second surface, thereby providing cushioning and protecting the first screen. Furthermore, the first screen extends to the position of the second connector so that the first screen has a larger size, thereby reducing the black border of the electronic device screen.

[0022] In some embodiments, the first base component includes a first functional element and a first mid-frame, the first functional element fixing the first screen relative to the first mid-frame, at least a portion of the first sound hole being disposed in the first functional element, and at least a portion of the second sound hole being disposed in the first mid-frame; the second base component includes a second functional element and a second mid-frame, the second functional element fixing the first screen relative to the second mid-frame, and the second connector being respectively embedded in the second functional element and the second mid-frame.

[0023] In the technical solution of this disclosure embodiment, at least a portion of the first sound hole is disposed in the first middle frame, and at least a portion of the second sound hole is disposed in the first functional component. The first functional component is used to fix the first screen relative to the first middle frame, resulting in a more compact structure that helps to reduce the black border of the screen. The second connecting member is respectively embedded in the second functional component and the second middle frame, and the structure is made more compact through space reuse.

[0024] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

Detailed Implementation

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the specific technical solutions of this disclosure will be further described in detail below with reference to the accompanying drawings of the embodiments of this disclosure. The following embodiments are used to illustrate this disclosure, but are not intended to limit the scope of this disclosure.

[0040] In the embodiments of this disclosure, the terms "first" and "second" 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. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0041] Furthermore, in the embodiments of this disclosure, directional terms such as "up," "down," "left," and "right" are defined relative to the orientation in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation in which the components are placed in the accompanying drawings.

[0042] In the embodiments disclosed herein, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0043] In embodiments of this disclosure, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0044] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] This disclosure provides an electronic device, which can be any device with sound-emitting capabilities, such as a mobile phone, tablet computer, television, game console, etc. The mobile phone includes foldable screen phones, and the tablet computer includes foldable tablets, multi-functional tablets (e.g., tablets with foldable keyboards), etc.

[0046] Taking foldable phones as an example, in some technical solutions, the first and second bodies of the foldable phone can be folded and unfolded relative to each other. The first body is equipped with a sound-emitting device and a main screen, with the sound outlet located at the top of the first body. When the first and second bodies are unfolded relative to each other, the user mainly uses the sound outlet located on the first body, such as the sound outlet on the main screen. When the first and second bodies are folded relative to each other, the user may hold either the first or the second body. The position of the sound outlet varies depending on the user's grip, making it difficult for related technologies to meet the diverse grip and sound output needs of users.

[0047] In addition, the main screen is assembled onto the mid-frame with adhesive, and the adhesive space of the main screen affects the size of its black border area. The space between the main screen and the mid-frame along the thickness direction cannot be effectively utilized, making it difficult to meet the multi-pole sound output requirements of the sound output structure.

[0048] Furthermore, this disclosure also provides a sound output structure, referring to... Figure 1 , Figure 2 and Figure 3 The sound-emitting structure includes a first base component 100 and a second base component 200. The first base component 100 is provided with a first sound outlet 110, a second sound outlet 120 and a receiving space 130. The receiving space 130 is used to receive the sound-emitting device 500. The first sound outlet 110 and the second sound outlet 120 are respectively connected to the receiving space 130. The opening of the first sound outlet 110 and the opening of the second sound outlet 120 are located on different surfaces of the first base component 100. The opening of the first sound outlet 110 is located on the first surface 140 of the first base component 100. The second base component 200 is provided with a third sound outlet 210. The third sound outlet 210 has openings on different surfaces of the second base component 200, and at least one opening of the third sound outlet 210 is located on the second surface 220 of the second base component 200. The second base component 200 is movably connected to the first base component 100. When the first base component 100 and the second base component 200 are switched to a folded state, the first surface 140 and the second surface 220 are arranged opposite to each other, and the first sound outlet 110 and the third sound outlet 210 are connected.

[0049] In this embodiment of the disclosure, the sound-producing device 500 produces sound based on electrical signals. The sound-producing device 500 may include a housing, and a magnet, coil, vibrator, tuning component, protective structure, etc., disposed within the housing. For example, the sound-producing device 500 is the earpiece of a mobile phone, which has functions such as call and media audio output.

[0050] In some examples, the opening of the first sound outlet 110 and the opening of the second sound outlet 120 are disposed on adjacent surfaces of the first substrate assembly 100, that is, the surface where the opening of the second sound outlet 120 is located is adjacent to the first surface 140; in other examples, the opening of the first sound outlet 110 and the opening of the second sound outlet 120 are disposed on opposite surfaces of the first substrate assembly 100, that is, the surface where the opening of the second sound outlet 120 is located is opposite to the first surface 140. For example, the first sound outlet 110 includes a first opening 111, and the second sound outlet 120 includes a second opening 121, with the first opening 111 and the second opening 121 disposed on opposite sides of the first substrate assembly 100.

[0051] In some examples, the second substrate component 200 has openings for the third sound outlet 210 on two adjacent surfaces, while in other examples, the second substrate component 200 has openings for the third sound outlet 210 on two opposing surfaces. It should be noted that the third sound outlet 210 needs to be connected to the first sound outlet 110, with part of the opening of the third sound outlet 210 serving as a sound inlet and the other part serving as a sound outlet.

[0052] For example, the third sound outlet 210 includes a third opening 211 and a fourth opening 212. The third opening 211 is located on the second surface 220 and serves as a sound inlet. The fourth opening 212 serves as a sound outlet. The fourth opening 212 and the third opening 211 are located on opposite sides of the second substrate assembly 200.

[0053] Figure 2 The middle arrows illustrate the sound transmission path within the first substrate assembly 100 and the second substrate assembly 200. The sound is emitted by the sound-emitting device 500 and can be transmitted through the first sound outlet 110 and the second sound outlet 120, respectively. The sound can also pass through the first sound outlet 110 into the third sound outlet 210 and be transmitted through the fourth opening 212 of the third sound outlet 210.

[0054] In some examples, the first sound outlet 110 is a uniform diameter hole, meaning its inner diameter is evenly distributed. In other examples, the first sound outlet 110 is a variable diameter hole, where its inner diameter can be gradually varied or stepped. In this embodiment, the radial profile of the first sound outlet 110 can be a regular or irregular shape such as a circle, ellipse, triangle, square, trapezoid, or hexagon. For example, the first sound outlet 110 is a uniform diameter circular hole.

[0055] In this embodiment of the disclosure, there may be one or more first sound outlets 110; each first sound outlet 110 may include one or more first openings 111, and the plurality of first sound outlets 110 or the plurality of first openings 111 may be arranged in a linear array, a rectangular array, or a circular array. (Refer to...) Figure 8 In some examples, the first base component 100 is provided with a plurality of first sound holes 110 arranged in a linear array, and each first sound hole 110 includes a first opening 111.

[0056] In some examples, the second sound outlet 120 is a uniform diameter hole, meaning its inner diameter is evenly distributed. In other examples, the second sound outlet 120 is a variable diameter hole, where its inner diameter can be gradually varied or stepped. In this embodiment, the radial profile of the second sound outlet 120 can be a regular or irregular shape such as a circle, ellipse, triangle, square, trapezoid, or hexagon. For example, the second sound outlet 120 is a rectangular hole with a uniform diameter.

[0057] In this embodiment of the disclosure, there may be one or more second sound outlets 120; the second sound outlet 120 may include one or more second openings 121, and the plurality of second sound outlets 120 or the plurality of second openings 121 may be arranged in a linear array, a rectangular array or a circular array. In some examples, the first substrate component 100 is provided with a second sound outlet 120, which includes a second opening 121.

[0058] In some examples, the third sound outlet 210 is a uniform diameter hole, meaning its inner diameter is evenly distributed. In other examples, the third sound outlet 210 is a variable diameter hole, where its inner diameter can be gradually varied or stepped. In this embodiment, the radial profile of the third sound outlet 210 can be a regular or irregular shape such as a circle, ellipse, triangle, square, trapezoid, or hexagon. For example, the third sound outlet 210 is a uniform diameter circular hole.

[0059] In this embodiment of the disclosure, the third sound outlet 210 can be one or more; the third sound outlet 210 can include one or more third openings 211, and the third sound outlet 210 can include one or more fourth openings 212. Multiple third sound outlets 210, multiple third openings 211, or multiple fourth openings 212 can be arranged in a linear array, a rectangular array, or a circular array. (Refer to...) Figure 6 and Figure 7 In some examples, the second substrate component 200 is provided with a plurality of third sound holes 210 arranged in a linear array, each third sound hole 210 including a third opening 211 and a fourth opening 212.

[0060] In this embodiment of the disclosure, the extension axes of the first sound outlet 110, the second sound outlet 120, and the third sound outlet 210 are not limited, and the extension axes can be straight lines, curves, broken lines, etc. In some examples, the extension axes of the first sound outlet 110, the second sound outlet 120, and the third sound outlet 210 are all straight lines, which helps to shorten the sound transmission path and reduce sound loss during transmission.

[0061] In some examples, the first base component 100 and the second base component 200 are connected by a pivot, and the first base component 100 and the second base component 200 can rotate relative to each other; in other examples, the first base component 100 and the second base component 200 are connected by a sliding component, and the first base component 100 and the second base component 200 can slide relative to each other in at least one direction.

[0062] In this embodiment of the disclosure, the first surface 140 and the second surface 220 are opposite to each other and projected along the vertical direction of the first surface 140 or the second surface 220. The projections of the first surface 140 and the second surface 220 at least partially overlap. The first surface 140 and the second surface 220 may be parallel or have an angle of less than 15 degrees.

[0063] In the technical solution of this embodiment, the accommodating space 130 of the first base component 100 is used to accommodate the sound-producing device 500, which is capable of generating sound. The first sound outlet 110 and the second sound outlet 120 of the first base component 100 are respectively connected to the accommodating space 130. The sound generated by the sound-producing device 500 can be transmitted out of the first base component 100 through the first sound outlet 110 and the second sound outlet 120 so that it can be obtained by the user. The opening of the first sound outlet 110 and the opening of the second sound outlet 120 are located on different surfaces of the first base component 100, that is, the first base component 100 can achieve sound output from multiple directions.

[0064] Based on this, the second base component 200 is provided with a third sound outlet 210, and the third sound outlet 210 has openings on different surfaces of the second base component 200 respectively. The first base component 100 and the second base component 200 are movably connected. When the first base component 100 and the second base component 200 are switched to a folded state, the first surface 140 of the first base component 100 and the second surface 220 of the second base component 200 are arranged opposite to each other, so that the opening of the third sound outlet 210 on the second surface 220 is connected to the first sound outlet 110. The sound emitted by the sound-emitting device 500 can be transmitted to the third sound outlet 210 through the first sound outlet 110, and the sound is transmitted out of the second base component 200 through the openings of the third sound outlet 210 on other surfaces. In the non-folded state, sound is emitted from multiple directions through the first sound outlet 110 and the second sound outlet 120. In the folded state, sound is emitted from multiple directions through the second sound outlet 120 and the third sound outlet 210. This can meet the diverse usage needs of users, and the sound-emitting device 500 only needs to be set in the first base component 100, which also helps to simplify the structure.

[0065] Compared with related technologies, the sound output structure is difficult to meet the diverse needs of users. The sound output structure of this embodiment can achieve sound output from multiple directions in both folded and unfolded states, which has better scene adaptability. Furthermore, the first sound output hole 110, the second sound output hole 120 and the third sound output hole 210 share a single sound output structure, which helps to simplify the structure and also helps to ensure the consistency of the sound output effect.

[0066] Reference Figure 2 In some embodiments of this disclosure, the first substrate assembly 100 further includes a third surface 150, and the opening of the second sound outlet 120 is located on the third surface 150; the second substrate assembly 200 further includes a fourth surface 230, and at least one opening of the third sound outlet 210 is disposed on the fourth surface 230.

[0067] In some examples, the third surface 150 is disposed opposite to the first surface 140, that is, the first surface 140 and the third surface 150 are located on opposite sides of the first substrate assembly 100, and when projected along the vertical direction of the first surface 140 or the third surface 150, the projection of the first surface 140 and the projection of the second surface 220 at least partially overlap. For example, the first surface 140 is the surface on which the main screen is disposed, the third surface 150 is the surface on which the sub-screen or cover 270 is disposed, the first opening 111 is located on the first surface 140, and the second opening 121 is located on the third surface 150. In other examples, the third surface 150 is disposed adjacent to the first surface 140, for example, the first surface 140 is the surface on which the main screen is disposed, and the third surface 150 is a sidewall or endwall of the first substrate assembly 100.

[0068] In some examples, the fourth surface 230 is disposed opposite to the second surface 220, that is, the second surface 220 and the fourth surface 230 are located on opposite sides of the second base assembly 200, respectively. Projected along the vertical direction of the second surface 220 or the fourth surface 230, the projections of the second surface 220 and the fourth surface 230 at least partially overlap. For example, the second surface 220 is the surface where the main screen is disposed, the fourth surface 230 is the surface where the sub-screen or cover 270 is disposed, the third opening 211 is located on the second surface 220, and the fourth opening 212 is located on the fourth surface 230. In other examples, the second surface 220 and the fourth surface 230 are disposed adjacent to each other; for example, the second surface 220 is the surface where the main screen is disposed, and the fourth surface 230 is a sidewall or endwall of the second base assembly 200.

[0069] In some examples, the first surface 140 and the third surface 150, which are set opposite to each other, may be parallel; in other examples, the first surface 140 and the third surface 150, which are set opposite to each other, have an angle of less than 15 degrees.

[0070] In some examples, the second surface 220 and the fourth surface 230, which are set opposite to each other, may be parallel; in other examples, the second surface 220 and the fourth surface 230, which are set opposite to each other, have an angle of less than 15 degrees.

[0071] It should be noted that the edges of the first base component 100 and the second base component 200 may be chamfered, that is, the edge areas of the first surface 140, the second surface 220, the third surface 150 and the fourth surface 230 are arc-shaped surfaces, and the first opening 111, the second opening 121, the third opening 211 and the fourth opening 212 may be set in the arc-shaped surface area of ​​the corresponding surface.

[0072] In the technical solution of this embodiment, the third surface 150 of the first base component 100 is disposed opposite to the first surface 140, and the opening of the second sound outlet 120 is disposed on the third surface 150. In the non-folded state, the second sound outlet 120 and the first sound outlet 110 can emit sound in opposite directions. The fourth surface 230 of the second base component 200 is disposed opposite to the second surface 220. In the folded state, the third sound outlet 210 and the second sound outlet 120 can emit sound in opposite directions to meet the sound emission needs of users with different grip directions.

[0073] Furthermore, by using a single sound-producing device 500 to produce two sounds with opposite phases, with a phase angle difference of 180 degrees, a trough can be generated along the sound axis to cancel out some of the sound, creating a non-concentrated, diffuse, and enveloping surround field. This allows the user to hear the sound from one direction while the sounds from the other two directions are canceled out, preventing others from hearing them. This effectively protects the user's call information and provides the user with a wider sense of atmosphere.

[0074] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of this disclosure, the first base assembly 100 further includes a first connector 160, and the opening of the first sound outlet 110 is disposed in the first connector 160. The second base assembly 200 further includes a second connector 240, and a portion of the opening of the third sound outlet 210 is disposed in the second connector 240. When the first base assembly 100 and the second base assembly 200 are switched to a folded state, the first connector 160 and the second connector 240 are sealed together, connecting the first sound outlet 110 and the third sound outlet 210.

[0075] In this embodiment of the present disclosure, the first connector 160 and the second connector 240 can be in the form of a block structure, a plate structure, a shell structure, etc., and this embodiment of the present disclosure does not limit this. In some examples, the first connector 160 is a plate structure and the second connector 240 is a block structure.

[0076] In some examples, the inner wall of the third sound outlet 210 is formed by the second connector 240, while in other examples, the inner wall of the third sound outlet 210 is formed by the second connector 240 and other components (such as the second functional component 250).

[0077] In some examples, the second connector 240 includes a first joint 243 and a second joint 244. The first joint 243 is provided with a third opening 211, and the second joint 244 is provided with a fourth opening 212. The first joint 243 and the second joint 244 are offset along the axial direction of the third sound outlet 210 to accommodate other structures of the second base assembly 200.

[0078] In some examples, the first opening 111 of the first sound outlet 110 is disposed on the first connector 160, and the third opening 211 and the fourth opening 212 of the third sound outlet 210 are disposed on the second connector 240.

[0079] In some examples, the first connector 160 and the second connector 240 are sealed together, meaning that the corresponding surfaces of the first connector 160 and the second connector 240 are tightly fitted, making it difficult for sound to escape from the gap between the first connector 160 and the second connector 240.

[0080] The technical solution of this embodiment of the disclosure, by setting a first connector 160 and a second connector 240, the opening of the first sound outlet 110 is set in the first connector 160, and the third sound outlet 210 is connected to the opening of the first sound outlet 110 set in the second connector 240. The first connector 160 and the second connector 240 are sealed together, thereby connecting the first sound outlet 110 and the third sound outlet 210. The sealed connection also helps to reduce the distortion and attenuation of sound during transmission, so as to improve the sound output effect of the third sound outlet 210.

[0081] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of this disclosure, the first connector 160 is provided with a sealing groove 161, which surrounds the opening of the first sound outlet 110; the second connector 240 is provided with a sealing protrusion 241, which surrounds the opening of the third sound outlet 210; the sealing protrusion 241 extends into the sealing groove 161 to seal the connection between the first connector 160 and the second connector 240.

[0082] In some examples, the opening of the sealing groove 161 is located on the first surface 140, the depth direction of the sealing groove 161 is perpendicular to the first surface 140, and the sealing groove 161 is annularly arranged. The surrounding shape of the sealing groove 161 can be a regular or irregular shape such as a circle, ellipse, square, rhombus, or trapezoid. For example, the surrounding shape of the sealing groove 161 is racetrack-shaped.

[0083] In some examples, the sealing protrusion 241 protrudes along a direction perpendicular to the second surface 220. The sealing protrusion 241 is annular and surrounds the third opening 211 of the third sound outlet 210. The surrounding shape of the sealing protrusion 241 can be regular or irregular, such as circular, elliptical, square, rhomboid, or trapezoidal. For example, the surrounding shape of the sealing protrusion 241 is racetrack-shaped.

[0084] It should be noted that the first connector 160 may be provided with multiple first openings 111. In some examples, there are multiple sealing grooves 161, and the multiple sealing grooves 161 correspond one-to-one with the multiple first openings 111; in other examples, the sealing grooves 161 surround at least two first openings 111.

[0085] Correspondingly, the second connector 240 may be provided with a plurality of third openings 211. In some examples, there are multiple sealing protrusions 241, and the multiple sealing protrusions 241 correspond one-to-one with the multiple third openings 211; in other examples, the sealing protrusions 241 surround at least two third openings 211. The sealing protrusions 241 are connected to the sealing grooves 161 in a one-to-one correspondence.

[0086] Reference Figure 8 , Figure 9 and Figure 10 In some examples, the sealing protrusion 241 extends into the corresponding sealing groove 161, and the outer wall of the sealing protrusion 241 fits against the inner wall of the sealing groove 161, isolating the space between the first sound outlet 110 and the third sound outlet 210 from the outside world, so that the first connector 160 and the second connector 240 are sealed together.

[0087] In other embodiments of this disclosure, the second connector 240 is provided with a sealing groove 161, which surrounds the opening of the third sound outlet 210; the first connector 160 is provided with a sealing protrusion 241, which surrounds the opening of the first sound outlet 110; the sealing protrusion 241 extends into the sealing groove 161 to seal the first connector 160 and the second connector 240 together.

[0088] In the technical solution of this embodiment, the first connector 160 and the second connector 240 have a large contact area through the cooperation of the sealing protrusion 241 and the sealing groove 161, and the contact surface of the two has a relatively complex structure, which helps to improve the sealing effect and thus improve the sound output effect of the third sound outlet 210.

[0089] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of this disclosure, the inner wall of the sealing groove 161 is provided with an elastic protrusion 242 that abuts against the outer wall of the sealing protrusion 241; and / or, the outer wall of the sealing protrusion 241 is provided with an elastic protrusion 242 that abuts against the inner wall of the sealing groove 161; wherein the elastic protrusion 242 elastically deforms at least along the abutting direction of the sealing protrusion 241 and the sealing groove 161.

[0090] In some examples, the inner wall of the sealing groove 161 is provided with an elastic protrusion 242; in other examples, the outer wall of the sealing protrusion 241 is provided with an elastic protrusion 242; in still other examples, both the inner wall of the sealing groove 161 and the outer wall of the sealing protrusion 241 are provided with elastic protrusions 242. The elastic protrusion 242 is used to achieve an interference fit between the sealing groove 161 and the sealing protrusion 241.

[0091] It is understood that the elastic protrusion 242 of the sealing groove 161 is an annular structure surrounding the first sound outlet 110, and the elastic protrusion 242 of the sealing protrusion 241 is an annular structure surrounding the third sound outlet 210. The multiple elastic protrusions 242 are arranged sequentially along the relative setting direction of the first surface 140 and the second surface 220.

[0092] In some examples, the abutting direction of the sealing protrusion 241 and the sealing groove 161 is parallel to the relative arrangement direction of the first surface 140 and the second surface 220; in other examples, the abutting direction of the sealing protrusion 241 and the sealing groove 161 is perpendicular to the relative arrangement direction of the first surface 140 and the second surface 220.

[0093] Understandably, in the folded state, the sealing protrusion 241 extends into the sealing groove 161, and the elastic protrusion 242 achieves an interference fit, connecting the first sound outlet 110 and the third sound outlet 210. In the non-folded state, the sealing protrusion 241 disengages from the sealing groove 161. This design does not affect the sealing connection between the first sound outlet 110 and the third sound outlet 210, and also facilitates the folding and unfolding of the first base assembly 100 and the second base assembly 200.

[0094] In the technical solution of this embodiment, an elastic protrusion 242 is provided between the inner wall of the sealing groove 161 and the outer wall of the sealing protrusion 241. The elastic protrusion 242 can be elastically deformed. Through the elastic deformation of the elastic protrusion 242, it can adapt to the wall structure of the corresponding sealing groove 161 or sealing protrusion 241, thereby improving the sealing effect.

The surface of the decorative element 300 smoothly transitions relative to the surfaces of the first functional component 170 and the first connecting component 160 to compensate for the step difference between the first connecting component 160 and the first functional component 170, thereby improving the surface smoothness of the first base component 100, which helps reduce wear, enhances the grip, and improves aesthetics. The decorative element 300 can also be disposed between the second functional component 250 and the second connecting component 240. The surface of the decorative element 300 smoothly transitions relative to the surfaces of the second functional component 250 and the second connecting component 240 to compensate for the step difference between the second connecting component 240 and the second functional component 250, thereby improving the surface smoothness of the second base component 200, which also helps reduce wear, enhances the grip, and improves aesthetics.

The isolation structure 400 is connected to the sound-emitting device 500 and seals and isolates the accommodating space 130 into a first chamber 131 and a second chamber 132. The first sound outlet 110 is connected to the first chamber 131, and the second sound outlet 120 is connected to the second chamber 132.

[0104] In some examples, the isolation structure 400 includes a first seal 410 that surrounds the sound-producing device 500 and has an opening on the side of the isolation structure 400 facing the first surface 140, so that the sound-producing device 500 and the structure containing the first surface 140 form a first chamber 131; the first seal 410 has an opening on the side of the isolation structure 400 facing the third surface 150, so that the sound-producing device 500 and the structure containing the third surface 150 form a second chamber 132.

[0105] In some examples, the isolation structure 400 further includes an isolator 430 disposed between the screen and the sound-producing device 500. For example, the electronic device includes a first screen 600 located on a first surface 140, and the sound-producing device 500 has the isolator 430 disposed on the side facing the first surface 140, forming a first chamber 131 between the isolator 430 and the sound-producing device 500.

[0109] The sealing element may include materials such as rubber or foam, which fill gaps through elastic deformation and have good sealing performance. For example, the first sealing element 410 is a rubber element, and the second sealing element 420 is foam. The isolation element 430 may include metal, rubber, or plastic materials. For example, the isolation element 430 is a steel plate, which has good structural strength, can reduce the impact of sound waves on the screen, and can also provide support for the screen.

[0110] The technical solution of this embodiment of the disclosure provides an isolation structure 400 to isolate the accommodating space 130 into a first chamber 131 and a second chamber 132. The first chamber 131 is connected to the first sound outlet 110, and the second chamber 132 is connected to the second sound outlet 120. This helps to reduce the interference between the first sound outlet 110 and the second sound outlet 120, thereby optimizing the sound output effect.

[0111] Reference Figure 1 The electronic device provided in this embodiment includes a sound-producing device 500 and a sound-emitting structure of this embodiment. The first base component 100 and the second base component 200 switch between a folded state and an unfolded state. In the unfolded state, the extension surface of the first surface 140 overlaps with the extension surface of the second surface 220. The sound-producing device 500 is disposed in the receiving space 130 of the first base component 100 and is used to produce sound.

[0112] It should be noted that in the folded state, the first surface 140 of the first base component 100 is opposite to the second surface 220 of the second base component 200. In the unfolded state, the first base component 100 and the second base component 200 can be in an unfolded state or in a state where the first surface 140 and the second surface 220 form an acute or obtuse angle.

[0113] The technical solution of this disclosure embodiment includes an electronic device with a sound output structure. The sound output structure can output sound from multiple directions in both folded and unfolded states, which has good scene adaptability. Furthermore, the first sound output hole 110, the second sound output hole 120, and the third sound output hole 210 share a single sound output structure, which helps to simplify the structure and also helps to ensure the consistency of sound output quality.

[0114] Reference Figure 1 and Figure 2 In some embodiments of this disclosure, the electronic device further includes a first screen 600, which is located on a first surface 140 and a second surface 220 respectively; the second substrate assembly 200 further includes a second connector 240, a third sound outlet 210 is disposed on the second connector 240, the second connector 240 is an elastic member, and the first screen 600 extends to the position of the second connector 240; in the folded state, the second connector 240 can apply an elastic force to the first screen 600, and the second connector 240 elastically deforms at least along the relative arrangement direction of the first surface 140 and the second surface 220.

[0115] In some embodiments, the first screen 600 is a flexible screen. A portion of the first screen 600 is connected to the first substrate assembly 100 and located on the first surface 140, while another portion of the first screen 600 is connected to the second substrate assembly 200 and located on the second surface 220. During relative movement between the first substrate assembly 100 and the second substrate assembly 200, the first screen 600 can be bent and folded.

[0117] In some examples, the second connector 240 can contact the portion of the first screen 600 located on the first base assembly 100, and the second connector 240 directly applies an elastic force to the first screen 600; in other examples, the second connector 240 indirectly applies an elastic force to the first screen 600 by contacting the first connector 160, the first functional component 170, etc.

[0118] In the technical solution of this embodiment, since the second connector 240 is an elastic member, the first screen 600 can extend to the position of the second connector 240. Under external impact, the second connector 240 can elastically deform at least along the relative arrangement direction of the first surface 140 and the second surface 220, thereby providing cushioning and protecting the first screen 600. Furthermore, the first screen 600 extends to the position of the second connector 240 so that the first screen 600 has a larger size, thereby reducing the black border of the electronic device screen.

[0119] Reference Figure 2 In some embodiments of this disclosure, the first base assembly 100 includes a first functional component 170 and a first middle frame 180. The first functional component 170 fixes the first screen 600 relative to the first middle frame 180.

The second base assembly 200 includes a second functional component 250 and a second middle frame 260. The second functional component 250 fixes the first screen 600 relative to the second middle frame 260, and the second connector 240 is respectively embedded in the second functional component 250 and the second middle frame 260.

[0120] In some examples, the first functional component 170 is a screen pressing strip, and the first screen 600 is connected to the first middle frame 180. When the first functional component 170 is assembled to the first middle frame 180, the first functional component 170 abuts against the edge area of ​​the first screen 600.

In the folded state, the first screen 600 is located inside the electronic device, and the second screen 190 is located outside the electronic device.

[0123] In some examples, the second functional component 250 is a screen pressing strip, and the first screen 600 is connected to the second middle frame 260. When the second functional component 250 is assembled to the second middle frame 260, the second functional component 250 abuts against the edge area of ​​the second screen 190.

[0124] In some examples, the second base component 200 also includes a cover 270 located on the fourth surface 230. For example, the middle portion of the second connector 240 is embedded in the second middle frame 260, the portion of the second connector 240 having a third opening 211 is embedded in the second functional component 250, and the portion of the second connector 240 having a fourth opening 212 is embedded in the cover 270.

[0125] In some examples, the first screen 600 is fixed by the first functional component 170 and the second functional component 250, which can remove the screen adhesive. The first sound outlet 110 is set in the first functional component 170 and the second sound outlet 210 is set in the second functional component 250. While reducing the size of the black border, the vertical space of the first screen 180 is effectively utilized to achieve positive sound output on the side where the first screen 600 is located.

[0126] In the technical solution of this embodiment, at least a portion of the first sound hole 110 is disposed in the first middle frame 180, and at least a portion of the second sound hole 120 is disposed in the first functional component 170. The first functional component 170 is used to fix the first screen 600 relative to the first middle frame 180, which is relatively compact and helps to reduce the black border of the screen. The second connector 240 is respectively embedded in the second functional component 250 and the second middle frame 260, so that the structure is more compact through space reuse.
