It should also be understood that terms defined in general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] This application provides an electronic device. For example... Figures 1 to 3 As shown, the electronic device includes a first body 1 and a speaker 2. The first body 1 contains a functional module 3. The speaker 2 is located inside the first body 1 and includes a housing assembly 4 and a speaker unit 21 located inside the housing assembly 4. The housing assembly 4 has at least two interconnected resonant cavities 41, which cooperate to transmit sound output through the speaker unit 21. At least one resonant cavity 41 has a portion of its cavity wall structure formed through the housing 11 of the first body 1 and / or the outer wall of the functional module 3.

[0033] The aforementioned electronic devices can refer to different electronic devices such as smartphones, tablets, and laptops. This application does not limit the specific type of electronic device, as long as the electronic device has a speaker device 2.

[0034] The aforementioned electronic device may further include a second body, with the first body 1 and the second body rotatably connected. A display area may be formed on the second body, allowing the user to operate the electronic device via the first body 1. The second body then displays the operation results through the display area. For example, the first body 1 may be configured as the system terminal of the electronic device, and the second body may be configured as the display terminal. Of course, the first body 1 may have a display area to present content to the user. This application does not limit the specific form of the first body 1; it is sufficient that it can be equipped with the functional module 3 and the speaker device 2.

[0035] The first body 1 of the aforementioned electronic device may be provided with at least one functional module 3. The functional module 3 can be understood as a module in the electronic device that can perform functions, such as a processing module, power supply module, storage module, camera module, support structure module, input module, button module, rotation module, display module, etc.

[0036] The following description uses functional module 3 as the power supply module. In order to extend the continuous working time of electronic devices when there is no external power supply (such as a power socket), it is common practice to increase the size of the power supply module. As a result, the power supply module will occupy too much space in the first body 1. By using the outer wall of functional module 3 to form part of the cavity wall of at least one resonant cavity 41, the structure of functional module 3 in the first body 1 can be fully utilized. Especially when the size of functional module 3 is large, the structure in the first body 1 can be designed more reasonably, and the structural layout in the first body 1 can be as compact as possible.

[0037] The aforementioned functional module 3 can be arranged close to the speaker device 2 within the first body 1, meaning that no other modules are arranged between the functional module 3 and the speaker device 2. In this way, the structural design of a portion of the cavity wall of at least one resonant cavity 41 of the speaker device 2 formed by utilizing the outer wall of the functional module 3 can be more rational.

[0038] After receiving the audio signal transmitted by the electronic device, the aforementioned speaker device 2 vibrates through its built-in voice coil, diaphragm, and other components, and ultimately transmits these vibrations through the air to generate sound, thus realizing the conversion of electrical signals into sound signals. The aforementioned speaker unit 21 may include built-in voice coil, diaphragm, and other components. The housing assembly 4 can accommodate the speaker unit 21 and can also transmit vibrations through the air in at least two interconnected resonant cavities 41, that is, further enhance and regulate the sound through the resonance effect, thereby achieving the purpose of transmitting the sound output by the speaker unit 21 through the cooperation of at least two resonant cavities 41.

[0039] In some embodiments, the above-mentioned at least two interconnected resonant cavities 41 can be understood as multiple resonant cavities 41 connected in sequence, such as resonant cavity A, resonant cavity B and resonant cavity C connected in sequence, resonant cavity A and resonant cavity C being connected through resonant cavity B, while resonant cavity A and resonant cavity C are not directly connected.

[0040] In some other embodiments, the above-mentioned at least two connected resonant cavities 41 can be understood as multiple resonant cavities 41 being interconnected, such as any two of resonant cavities A, B and C being interconnected.

[0041] At least one cavity wall of the aforementioned resonant cavity 41 can be partially formed via the outer wall of the housing 11, rather than via the outer wall of the functional module 3. It is understood that the other cavity walls of the resonant cavity 41 can be formed via other housings within the first body 1. That is, the other housings within the first body 1 cooperate with the housing 11 to form the resonant cavity 41, facilitating flexible placement of the resonant cavity 41's position and size. Alternatively, the other cavity walls of the resonant cavity 41 can also be formed via the outer wall of the housing 11, meaning the entire resonant cavity 41 is formed via the housing 11, thus ensuring structural stability of the resonant cavity 41.

[0042] A portion of the cavity wall of at least one resonant cavity 41 can be constructed via the outer wall of the functional module 3, rather than via the housing 11. It is understood that a portion of the cavity wall of at least one resonant cavity 41 can be formed by the outer wall of one or more different functional modules 3. The other cavity walls of the resonant cavity 41 can be formed via other housings within the first body 1. That is, the other housings within the first body 1 cooperate with the outer wall of the functional module 3 to form the resonant cavity 41, facilitating flexible setting of the position and size of the resonant cavity 41. Of course, the other cavity walls of the resonant cavity 41 can also be formed via the outer wall of the functional module 3, meaning the entire resonant cavity 41 is formed via the outer wall of the functional module 3.

[0043] The cavity wall of at least one resonant cavity 41 can be constructed to be formed via the outer wall of the housing 11 and the functional module 3. It is understood that the housing 11 can form part of the cavity wall of the resonant cavity 41 with the outer wall of one functional module 3, or with the outer walls of multiple functional modules 3. This can make fuller use of the structural space within the first body 1 and further reduce the size of the structure forming the resonant cavity 41 from the size of the resonant cavity 41 itself.

[0044] This application utilizes at least two interconnected resonant cavities 41 of the shell assembly 4, with at least one cavity wall of the resonant cavity 41 partially formed via the outer wall of the housing 11 of the first body 1 and / or the functional module 3. This allows the size of the resonant cavity 41 to be maximized by utilizing the outer wall of the housing 11 of the first body 1 and / or the functional module 3. The resonance effect of at least two resonant cavities 41 further enhances and modulates the sound, improves the sound output of the speaker device 2, optimizes the sound output of the electronic device, and reduces the size of the structure forming the resonant cavity 41 from the size of the resonant cavity 41 itself. This allows the resonant cavity 41 to be formed using other structures of the electronic device besides the speaker device 2, making the structure of the electronic device more rational.

[0045] In some embodiments, such as Figure 1 As shown, the functional module 3 and the speaker 2 can be arranged side by side in the first body 1, and an operating area 12 can be formed on the housing 11 of the first body 1.

[0046] Thus, at least one cavity wall of a resonant cavity 41 can be formed by the functional module 3 arranged in parallel with the speaker device 2 within the first body 1, and / or the housing 11 having the operating area 12, thereby achieving a more rational use of the structural components around the speaker device 2 to form a portion of the cavity wall of the resonant cavity 41.

[0047] The aforementioned operating area 12 can be understood as the area where the user performs input operations, such as the keyboard area, touchpad area, touchscreen area, etc. Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 The operation area 12 shown is a keyboard area, which is only an example. This application does not limit the specific form of the operation area 12, as long as it can receive user input.

[0048] The aforementioned speaker device 2 may be one or more, such as Figure 1 and Figure 2 As shown in the figure, the two speaker devices 2 shown are only examples. The sound output effect of the speaker devices 2 can be improved by increasing the number of speaker devices 2.

[0049] When there are multiple speaker devices 2, the multiple speaker devices 2 can be respectively set on opposite sides of the functional module 3, or arranged around the periphery of the functional module 3, so as to make full use of the space inside the first body 1 without affecting the setting space of the functional module 3, so as to improve the sound output effect of the speaker devices 2.

[0050] The space occupied by the aforementioned functional module 3 within the first body 1 is greater than the space occupied by the speaker device 2 within the first body 1. In order to meet the actual needs of users, the functions implemented by the functional module 3 can be understood as functions that are of high user concern, that is, functions that can significantly improve the user experience, such as battery life, task processing speed, device storage space, etc. To meet the functions of the functional module 3, the size of the functional module 3 is usually increased. Therefore, by using the outer wall of the functional module 3 to form part of the cavity wall of the resonant cavity 41, the structural design of the functional module 3 can be fully utilized. While ensuring the size design of the functional module 3, the size of the resonant cavity 41 can be increased as much as possible, thereby improving the sound output effect of the speaker device 2.

[0051] In some embodiments, such as Figures 3 to 6 As shown, at least one resonant cavity 41 is isolated from the outer wall of the housing 11 and / or the functional module 3 of the first body 1. Hereinafter, the resonant cavity 41 is referred to as the isolation cavity.

[0052] Thus, by isolating the isolation cavity from the outer wall of the housing 11 and / or the functional module 3 of the first body 1, the vibration generated by the resonance effect in the isolation cavity can be reduced from being transmitted to the housing 11 and / or the functional module 3, thereby reducing the vibration transmission. This can prevent the housing 11 from vibrating excessively and affecting the user's use, and also prevent the functional module 3 from vibrating excessively and affecting its service life.

[0053] The isolation between the aforementioned isolation cavity and the outer wall of the housing 11 and / or functional module 3 of the first body 1 can be understood as the isolation cavity not being in direct contact with the housing 11 and / or functional module 3, thus preventing the transmission of air vibrations within the isolation cavity to the housing 11 and / or functional module 3.

[0054] The aforementioned isolation cavity can be suspended within the first body 1, and the isolation cavity is not in direct contact with other structural components within the first body 1. In this way, the vibration generated by the resonance effect within the isolation cavity can be prevented from being transmitted outward as much as possible, thereby further improving the sound output effect of the loudspeaker 2 and avoiding excessive noise caused by vibration.

[0055] The aforementioned speaker unit 21 can be disposed within an isolation cavity, which can be formed separately via a portion of the shell assembly 4 of the speaker device 2 to avoid direct contact with other structural components.

[0056] The cavity wall of the aforementioned isolation cavity can be made of materials such as vibration damping and sound absorption materials to absorb vibration and reduce resonance effects, thereby effectively reducing the propagation of excess vibration caused by resonance.

[0057] In some embodiments, such as Figures 4 to 6As shown, at least two resonant cavities 41 include at least a first resonant cavity 42 and a second resonant cavity 43. A portion of the cavity wall of the second resonant cavity 43 is formed via the outer wall of the housing 11 and / or the functional module 3, and at least a portion of the second resonant cavity 43 is located between the housing 11 and the functional module 3.

[0058] In this way, a second resonant cavity 43 can be formed by utilizing the space between the housing 11 and the functional module 3, making full use of the space inside the first body 1. This not only does not affect the structural design of the functional module 3, but also allows the size of the resonant cavity 41 of the speaker device 2 to be increased in a reasonable manner by utilizing the gap between the functional module 3 and the housing 11. This further enhances and adjusts the sound through the resonance effect of the first resonant cavity 42 and the second resonant cavity 43, thereby improving the sound output effect of the speaker device 2.

[0059] The aforementioned speaker unit 21 can be disposed in the first resonant cavity 42. The sound output by the speaker unit 21 is first processed by the first resonant cavity 42 and then enters the second resonant cavity 43. Thus, the first resonant cavity 42 and the second resonant cavity 43 can transmit the sound output by the speaker unit 21 in sequence.

[0060] The aforementioned housing 11 may have an operation panel forming the operation area 12. The space between the housing 11 and the functional module 3 can be understood as the space between the housing 11 and the functional module 3 in a direction perpendicular to the operation panel.

[0061] To protect the functional module 3, a space is left between the functional module 3 and the housing 11 of the first body 1. For example, when the functional module 3 is a power supply module, a space is left between the power supply module and the housing 11 to ensure heat dissipation and provide a certain deformation space for the power supply module. Since the power supply module itself is relatively large, the size of this space corresponds to the size of the power supply module. Therefore, using this space to set up the second resonant cavity 43 can better achieve the purpose of increasing the size of the resonant cavity 41.

[0062] The first resonant cavity 42 and the second resonant cavity 43 mentioned above can be understood as two independent but connected cavities, and there is no relationship of inclusion or nesting between them.

[0063] The shapes of the first resonant cavity 42 and the second resonant cavity 43 may be the same or different. This application does not make specific limitations on this, as long as the first resonant cavity 42 and the second resonant cavity 43 can be stably connected.

[0064] In some embodiments, such as Figures 4 to 6 As shown, the first resonant cavity 42 is isolated from the outer wall of the housing 11 and / or the functional module 3 of the first body 1, and the first resonant cavity 42 and the second resonant cavity 43 are connected through the vibration damping structure 5.

[0065] Thus, vibration transmission can be reduced by isolating the first resonant cavity 42 from the outer wall of the housing 11 of the first body 1 and / or the functional module 3. This avoids excessive vibration of the housing 11 from affecting user operation and also prevents excessive vibration of the functional module 3 from affecting its service life. Furthermore, the first resonant cavity 42 and the second resonant cavity 43 are connected by the vibration damping structure 5, which can further reduce vibration transmission and provide installation leeway for the first resonant cavity 42 and the second resonant cavity 43 during installation, facilitating the stability of the sealed connection between the first resonant cavity 42 and the second resonant cavity 43.

[0066] The vibration damping structure 5 is made of elastic material, which can make the sealed connection between the first resonant cavity 42 and the second resonant cavity 43 more stable through the deformation of the vibration damping structure 5.

[0067] The first resonant cavity 42 mentioned above can be understood as the isolation cavity mentioned above. That is, the first resonant cavity 42 is not in direct contact with the housing 11 and / or the functional module 3, which can prevent the air vibration in the isolation cavity from being transmitted to the housing 11 and / or the functional module 3.

[0068] In some embodiments, such as Figures 3 to 7 As shown, the shell assembly 4 includes at least a first shell 44 and a second shell 45 connected to each other. The speaker unit 21 is located inside the first shell 44. The first shell 44 forms a first resonant cavity 42. At least a portion of the cavity wall of the second resonant cavity 43 is formed via the second shell 45.

[0069] Thus, the first resonant cavity 42 and at least part of the second resonant cavity 43 can be formed by the first housing 44 and the second housing 45 of the housing assembly 4, respectively. The vibration of the first housing is transmitted to the housing through the vibration damping structure and the second housing. In this way, compared with the integral housing, the present application can effectively reduce the vibration transmission by separating the first housing 44 and the second housing 45.

[0070] The first housing 44 can be detachably connected to the housing 11. For example, the first housing 44 extends outward to form a connecting portion, which is connected to the housing 11 via a connector. A vibration damping pad can be provided between the connecting portion and the housing 11 to further reduce vibration transmission to the housing 11.

[0071] The first housing 44 and the second housing 45 can be connected by a flexible connection, which can reduce the vibration transmission between the first housing 44 and the second housing 45.

[0072] In some embodiments, such as Figures 4 to 7As shown, the loudspeaker device 2 also includes a vibration damping structure 5. The first housing 44 is provided with a first connecting hole 46, and the second housing 45 is provided with a second connecting hole 47. The vibration damping structure 5 is connected to the first connecting hole 46 and the second connecting hole 47 respectively, so that the first housing 44 and the second housing 45 are sealed together.

[0073] In this way, the vibration damping structure 5 can be stably installed through the first connecting hole 46 and the second connecting hole 47, making the structural design of the loudspeaker device 2 more reasonable.

[0074] The first connecting hole 46 and the second connecting hole 47 can be designed to be as large as possible to allow air to circulate freely in the first resonant cavity 42 and the second resonant cavity 43, thereby improving the low-frequency performance of the speaker device 2. Specifically, the first housing 44 can have a first region corresponding to the second housing 45, and the first connecting hole 46 can cover the first region as much as possible. The second housing 45 can have a second region corresponding to the first housing 44, and the second connecting hole 47 can cover the second region as much as possible. This allows the sizes of the first connecting hole 46 and the second connecting hole 47 to be increased as much as possible to improve the low-frequency performance of the speaker device 2.

[0075] The shape of the first connecting hole 46 and the second connecting hole 47 can be one of the following: circular, rectangular, etc.

[0076] The outer wall of the aforementioned vibration damping structure 5 extends outward to form a spacer portion. The first housing 44 abuts against one end face of the spacer portion, and the second housing 45 abuts against the other end face of the spacer portion. In this way, the first housing 44 and the second housing 45 do not come into direct contact, thereby further reducing vibration transmission.

[0077] In some embodiments, such as Figure 4 and Figure 5 As shown, the second housing 45 is open on the side facing the housing 11, and the side of the second housing 45 facing the housing 11 is provided with an adhesive layer 48 to be connected to the housing 11 through the adhesive layer 48.

[0078] In this way, the second housing 45 can be stably installed in the housing 11 through the adhesive layer 48, so that the second housing 45 and the housing 11 can cooperate to form the second resonant cavity 43.

[0079] The aforementioned adhesive layer 48 can circumferentially cover the side of the second housing 45 facing the housing 11, so that after the second housing 45 is bonded to the housing 11, the connection between the second housing 45 and the housing 11 can be sealed.

[0080] In some embodiments, such as Figure 1 and Figure 2As shown, the housing 11 is also provided with a plurality of limiting members 13 for limiting the position of the functional module 3. The plurality of limiting members 13 are located between the functional module 3 and the housing 11, and at least part of the second resonant cavity 43 is located between the plurality of limiting members 13.

[0081] In this way, the functional module 3 and the housing 11 can be kept in a stable relative position by multiple limiting members 13. On this basis, at least part of the second resonant cavity 43 is located between multiple limiting members 13, which can make more reasonable use of the space between the functional module 3 and the housing 11.

[0082] The aforementioned multiple limiting members 13 can be arranged relatively far apart so that a larger space can be formed between the multiple limiting members 13, so as to maximize the size of the second resonant cavity 43.

[0083] The side of the aforementioned limiting member 13 facing the second resonant cavity 43 can be used to form part of the cavity wall of the second resonant cavity 43, so as to form the second resonant cavity 43 through the limiting member 13 in conjunction with the outer wall of the housing 11 and / or the functional module 3, thereby further reducing the size of the structure forming the resonant cavity 41 from the size of the resonant cavity 41 itself, realizing the formation of the resonant cavity 41 by using the limiting member 13, making the design of the resonant cavity 41 of the speaker device 2 more rational.

[0084] In some embodiments, such as Figures 1 to 5 As shown, the functional module 3 and the speaker device 2 are arranged side by side in the first body 1. The second resonant cavity 43 includes a first cavity 49 and a second cavity 410 that are connected. The first cavity 49 is located between the housing 11 and the functional module 3, and the second cavity 410 is located between the housing 11 and the speaker device 2.

[0085] Thus, through the first cavity 49 and the second cavity 410 of the second resonant cavity 43, the second resonant cavity 43 can make full use of the space between the housing 11 and the functional module 3, and can also extend between the housing 11 and the speaker 2 to achieve a sealed connection with the first resonant cavity 42.

[0086] The aforementioned second connection hole 47 can be provided corresponding to the second cavity 410, and the second connection hole 47 can cover the second cavity 410 as much as possible.

[0087] The shapes of the first cavity 49 and the second cavity 410 may be the same or different; this application does not impose specific limitations on this, as long as the first cavity 49 and the second cavity 410 can be stably connected. For example, as shown... Figure 5 As shown, both the first cavity 49 and the second cavity 410 are rectangular in shape.

[0088] This application provides an electronic device. For example... Figures 1 to 4As shown, the electronic device includes a first body 1 and a speaker 2. The first body 1 contains a functional module 3. The speaker 2 is located within the first body 1 and includes a resonant cavity 41 and a speaker unit 21 disposed within the resonant cavity 41. At least a portion of the cavity wall of the resonant cavity 41 is formed through the outer wall of the housing 11 of the first body 1 and / or the functional module 3, and a portion of the resonant cavity 41 is located between the housing 11 and the functional module 3.

[0089] The first body 1 of the aforementioned electronic device may be provided with at least one functional module 3. The functional module 3 can be understood as a module in the electronic device that can perform functions, such as a processing module, power supply module, storage module, camera module, support structure module, input module, button module, rotation module, display module, etc.

[0090] In related technologies, there is a gap between the housing 11 of the first body 1 and the power supply module. This is beneficial for providing heat dissipation space for the power supply module or, in the event of a power supply module failure (such as bulging, leakage, etc.), preventing the power supply module from causing damage to the housing, such as squeezing and deformation of the housing or corrosion of the housing.

[0091] Taking the aforementioned functional module 3 as a power supply module as an example, in one embodiment of this application, the functional module can be a power supply module, and at least part of the cavity wall is made of thermally conductive material and / or elastic material. By setting a portion of the resonant cavity 41 between the housing 11 and the functional module 3, this portion of the resonant cavity can be made of thermally conductive material (e.g., copper, aluminum, etc.). This portion of the resonant cavity can increase the volume of the resonant cavity while providing heat dissipation for the power supply module, increasing the space utilization of the electronic device. Using this space to form a portion of the resonant cavity 41 of the speaker device 2 achieves a balanced optimization of the design of the power supply module and the speaker device 2, making the internal structure design of the first body 1 of the electronic device more reasonable.

[0092] Taking the aforementioned functional module 3 as an example of a power supply module, in another embodiment of this application, by setting a portion of the resonant cavity 41 between the housing 11 and the functional module 3, this portion of the resonant cavity can also be made of an elastic material, or a material that can provide both thermal conductivity and elasticity. In the event of a power supply module failure (such as bulging, leakage, etc.), this portion of the resonant cavity can provide deformation space for the power supply module through elastic deformation, which can avoid damage to the housing in the event of a power supply module failure and increase the space utilization rate of the electronic device.

[0093] Furthermore, at least a portion of the cavity wall of the resonant cavity 41 in this application is formed via the outer wall of the housing 11 of the first body 1 and / or the outer wall of the functional module 3. This allows the size of the resonant cavity 41 to be increased as much as possible using the outer wall of the housing 11 of the first body 1 and / or the outer wall of the functional module 3. The resonance effect of at least two resonant cavities 41 further enhances and modulates the sound, improves the sound output of the speaker device 2, and achieves the purpose of optimizing the sound output of the electronic device. It also reduces the size of the structure forming the resonant cavity 41 from the size of the resonant cavity 41 itself. This allows the resonant cavity 41 to be formed using other structures of the electronic device besides the speaker device 2, making the structure of the electronic device more rational.

[0094] The aforementioned functional module 3 can be arranged close to the speaker device 2 within the first body 1, meaning that no other modules are arranged between the functional module 3 and the speaker device 2. In this way, the structural design of the resonant cavity 41 of the speaker device 2, which utilizes the outer wall of the functional module 3, can be made more rational.

[0095] After receiving the audio signal transmitted by the electronic device, the aforementioned speaker device 2 vibrates through its built-in voice coil, diaphragm, and other components, and ultimately transmits these vibrations through the air to generate sound, thus realizing the conversion of electrical signals into sound signals. The aforementioned speaker unit 21 may include built-in voice coil, diaphragm, and other components. The resonant cavity 41 can accommodate the speaker unit 21 and can also transmit vibrations through the air in at least two interconnected resonant cavities 41, that is, further enhance and regulate the sound through the resonance effect, thereby achieving the purpose of transmitting the sound output by the speaker unit 21 through the cooperation of at least two resonant cavities 41.

[0096] Part of the cavity wall of the aforementioned resonant cavity 41 can be constructed to be formed via the outer wall of the housing 11, rather than via the outer wall of the functional module 3. It is understood that the other cavity walls of the resonant cavity 41 can be formed via other housings within the first body 1. That is, the other housings within the first body 1 cooperate with the housing 11 to form the resonant cavity 41, facilitating flexible placement of the position and size of the resonant cavity 41. Of course, the other cavity walls of the resonant cavity 41 can also be formed via the outer wall of the housing 11, meaning the entire resonant cavity 41 is formed via the housing 11, thus giving the resonant cavity 41 structural stability.

[0097] The cavity wall of the aforementioned resonant cavity 41 can be partially formed via the outer wall of the functional module 3, rather than via the housing 11. Specifically, a portion of the cavity wall of the resonant cavity 41 can be formed by the outer walls of one or more different functional modules 3. The other cavity walls of the resonant cavity 41 can be formed via other housings within the first body 1. That is, the other housings within the first body 1 cooperate with the outer walls of the functional modules 3 to form the resonant cavity 41, facilitating flexible setting of the position and size of the resonant cavity 41. Alternatively, the other cavity walls of the resonant cavity 41 can also be formed via the outer walls of the functional modules 3, meaning the entire resonant cavity 41 is formed via the outer walls of the functional modules 3.

[0098] The cavity wall of the aforementioned resonant cavity 41 can be constructed to be formed via the outer wall of the housing 11 and the functional module 3. It is understood that the housing 11 can form part of the cavity wall of the resonant cavity 41 with the outer wall of one functional module 3, or it can form part of the cavity wall of the resonant cavity 41 with the outer walls of multiple functional modules 3. This can make fuller use of the structural space within the first body 1 and further reduce the size of the structure forming the resonant cavity 41 from the size of the resonant cavity 41 itself.

[0099] In some embodiments, the resonant cavity 41 includes at least a first resonant cavity 42 and a second resonant cavity 43, the first resonant cavity 42 and the second resonant cavity 43 are connected by a vibration damping structure 5, a portion of the cavity wall of the second resonant cavity 43 is formed via the outer wall of the housing 11 and / or the functional module 3, and at least a portion of the second resonant cavity 43 is located between the housing 11 and the functional module 3.

[0100] Thus, by setting the first resonant cavity 42 and the second resonant cavity 43 to be connected through the vibration damping structure 5, and by constructing part of the cavity wall of the second resonant cavity 43 through the outer wall of the housing 11 and / or the functional module 3, the vibration of the first resonant cavity 42 can be reduced from being transmitted to the housing 11 and / or the functional module 3 that form the second resonant cavity 43. This can prevent excessive vibration of the housing 11 from affecting the user's use, and also prevent excessive vibration of the functional module 3 from affecting its service life. Furthermore, the connection between the first resonant cavity 42 and the second resonant cavity 43 through the vibration damping structure 5 allows for installation leeway in the first resonant cavity 42 and the second resonant cavity 43, facilitating the stability of the sealed connection between the first resonant cavity 42 and the second resonant cavity 43.

[0101] The vibration damping structure 5 is made of elastic material, which can make the sealed connection between the first resonant cavity 42 and the second resonant cavity 43 more stable through the deformation of the vibration damping structure 5.

[0102] In some embodiments, such as Figures 3 to 7As shown, the loudspeaker device 2 may also include a housing assembly 4, which includes at least a first housing 44 and a second housing 45. The first housing 44 and the second housing 45 are connected by a vibration damping structure 5. The loudspeaker unit 21 is located inside the first housing 44. The first housing 44 forms the first resonant cavity 42 described above. At least a portion of the cavity wall structure of the second resonant cavity 43 described above is formed via the second housing 45.

[0103] Thus, the first resonant cavity 42 and at least part of the second resonant cavity 43 can be formed by the first housing 44 and the second housing 45 of the housing assembly 4, respectively. The vibration of the first housing 44 is transmitted to the housing 11 through the vibration damping structure 5 and the second housing 45. In this way, compared with the integral housing, the present application can effectively reduce the vibration transmission by separating the first housing 44 and the second housing 45.

[0104] The vibration damping structure 5 is made of elastic material, which can make the sealed connection between the first resonant cavity 42 and the second resonant cavity 43 more stable through the deformation of the vibration damping structure 5.
