Description

Technical Field

[0001] The present application belongs to the field of electronic technology, and specifically relates to a cavity sharing structure and electronic equipment. Background Art

[0002] With the continuous leap in performance of smart electronic devices like mobile phones and the escalating demand for audio-visual entertainment, internal space allocation has become a core contradiction constraining the industrial design of electronic devices. For example, hardware module cooling fans and top speakers are facing the dual pressures of functional enhancement and miniaturization. To meet the cooling requirements of high-performance chips, active turbofan cooling solutions are employed. However, these miniature fan modules often occupy 5% to 8% of the device's internal space, resulting in reduced battery capacity or a reconfigured motherboard layout. To achieve a stereo sound field and high-frequency response, speaker units are evolving toward high-amplitude modules. Combined with acoustic structures such as dust screens and resonant cavities, these units create a "special sound zone" at the top of full-screen phones, competing for space with components like the front camera and proximity sensor.

[0003] Generally speaking, the air duct needs to be unobstructed internally without affecting the internal protection of the entire machine. The upper speaker requires an independent and sealed rear cavity to improve the acoustic performance. For this reason, the existing technology adopts a solution in which the fan duct and the upper speaker are designed independently of each other, each occupying an independent cavity. However, this results in multiple hardware modules occupying the device space, causing equipment space pressure. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a cavity-sharing structure and electronic device, which can solve the problem that the fan duct and upper speaker of existing electronic devices are designed independently, each occupying an independent cavity, resulting in excessive occupation of equipment space and causing equipment space pressure.

[0005] In a first aspect, an embodiment of the present application proposes a cavity sharing structure, including:

[0006] A cavity structure, wherein the first end and the second end of the cavity structure are respectively provided with an air inlet and an air outlet relative to each other, and the third end of the cavity structure is provided with a speaker outlet;

[0007] a fan, the fan being arranged at the second end of the cavity structure;

[0008] a speaker, the speaker being arranged at a third end of the cavity structure;

[0009] a cavity switching structure, at least a portion of which is disposed inside the cavity structure;

[0010] A first cavity space is formed between the first end of the cavity structure, the middle of the cavity structure, and the second end of the cavity structure, and a second cavity space is formed between the third end of the cavity structure and the middle of the cavity structure. The first cavity space serves as an air duct for the fan, and the second cavity space serves as a sound channel for the speaker.

[0011] The cavity switching structure is used to put the first cavity space in a connected state when the fan is in a working state, and to put the second cavity space in a connected state when the speaker is in a working state.

[0013] case;

[0014] A cavity common structure is provided inside the shell, and the cavity common structure is the cavity common structure according to the first aspect.

[0015] In an embodiment of the present application, the cavity common structure includes: a cavity structure, wherein the first end and the second end of the cavity structure are respectively provided with relative air inlet and air outlet, and the third end of the cavity structure is provided with a speaker sound outlet; a fan, wherein the fan is arranged at the second end of the cavity structure; a speaker, wherein the speaker is arranged at the third end of the cavity structure; a cavity switching structure, wherein at least part of the cavity switching structure is arranged inside the cavity structure; wherein a first cavity space is formed between the first end of the cavity structure, the middle part of the cavity structure and the second end of the cavity structure, and a second cavity space is formed between the third end of the cavity structure and the middle part of the cavity structure, the first cavity space serves as the air duct of the fan, and the second cavity space serves as the sound channel of the speaker; the cavity switching structure is used to make the first cavity space in a connected state when the fan is in a working state, and to make the second cavity space in a connected state when the speaker is in a working state. In this way, by designing a structure in which the fan and the speaker share a cavity, an integrated module design structure is realized that combines the fan air duct and the speaker sound channel into one. In specific use, the cavity switching structure can be used to control the connection of the first cavity space or the second cavity space according to different working conditions. In this way, the structure can compress the equipment space occupied by the cavity structure while ensuring the fan's heat dissipation capacity and the speaker's sound quality, thereby reducing the equipment space pressure.

[0030] With the continuous advancement of smartphone performance and the escalating demand for audio-visual entertainment, internal space allocation has become a core constraint on mobile phone industrial design. Hardware modules, such as cooling fans and top speakers, are facing the dual pressures of increased functionality and miniaturization. The exponential growth in power consumption of high-performance chips has made traditional graphite chips inadequate for heat dissipation. Gaming phones have pioneered active cooling solutions with turbofans, but these miniature fan modules often occupy 5% to 8% of the device's internal space, resulting in reduced battery capacity or a reconfiguration of the motherboard layout. Regarding top speakers, users' pursuit of stereo sound and low-frequency response has driven the evolution of speaker units towards high-amplitude modules. Combined with acoustic structures such as dust filters and resonant chambers, these modules create a "specialized sound zone" at the top of full-screen phones, competing for space with components like the front camera and proximity sensor. Manufacturers are alleviating space pressures through innovative technologies such as specialized motherboard designs, composite heat dissipation material stacking, and piezoelectric ceramic speakers. However, balancing heat dissipation efficiency, audio quality, and battery life within a limited footprint remains a major engineering challenge for mobile phones in the 5G era.

[0031] The current design of the fan duct and upper speaker being independent of each other has the following disadvantages:

[0032] 1) Each occupies an independent cavity: The air duct needs to be unobstructed without affecting the internal protection of the entire device; the upper speaker requires an independent and sealed rear cavity to improve acoustic performance;

[0033] 2) In order to achieve higher acoustic performance in a smaller space, the upper speaker needs to fill the closed rear cavity with damping material particles to achieve a larger equivalent cavity, which results in higher costs.

[0034] The purpose of this application is to propose a method for realizing the linkage switching of the fan duct and the upper speaker through a single motor and its corresponding mechanism, so that the two can share part of the stacking space.

[0035] The improvements of this application are as follows:

[0036] 1) Cavity sharing: The fan duct and upper speaker share part of the space, saving space for stacking the entire unit;

[0037] 2) Cost saving: The rear cavity of the upper speaker is expanded by using the air duct, eliminating the need for filling damping material particles and reducing costs;

[0038] 3) Simple mechanism: The switching between the two cavities is achieved through a single motor and rotating ring mechanism.

[0039] The cavity sharing structure provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0040] See Figure 1 , Figure 1This is a schematic diagram of the cavity common structure provided in the embodiment of the present application. Figure 1 As shown, the cavity common structure 100 includes:

[0041] The cavity structure 10 has an air inlet 101 and an air outlet 102 at the first and second ends thereof, respectively, and a speaker sound outlet 103 at the third end thereof;

[0042] A fan 20 is provided at the second end of the cavity structure 10;

[0043] The speaker 30 is provided at the third end of the cavity structure 10;

[0044] a cavity switching structure 40 , at least a portion of which is disposed inside the cavity structure 10 ;

[0045] A first cavity space 110 is formed between the first end of the cavity structure 10, the middle portion of the cavity structure 10, and the second end of the cavity structure 10. A second cavity space 120 is formed between the third end of the cavity structure 10 and the middle portion of the cavity structure 10. The first cavity space 110 serves as an air duct for the fan 20, and the second cavity space 120 serves as a sound channel for the speaker 30.

[0046] The cavity switching structure 40 is used to keep the first cavity space 110 in a connected state when the fan 20 is in operation, and to keep the second cavity space 120 in a connected state when the speaker 30 is in operation.

[0047] The embodiment of the present application designs a cavity sharing structure 100 that can be applied to a fan and a speaker sharing a cavity in an electronic device, such as Figure 1 As shown, from the appearance, it includes a cavity structure 10 and a cavity switching structure 40. The fan 20 and the speaker 30 are both arranged inside the cavity structure 10. A cavity space is formed inside the cavity structure 10, which can serve as an air duct for the fan 20 or a sound channel for the speaker 30, that is, the fan 20 and the speaker 30 share the cavity space formed inside the cavity structure 10.

[0048] The cavity structure 10 includes a first end and a second end relative to each other, one of which can be set as an air outlet 102, and a fan 20 is set at an end near the air outlet 102. For example, the first end of the cavity structure 10 is set as the air inlet 101, and the second end of the cavity structure 10 is set as the air outlet 102. The fan 20 is set at an end near the air outlet 102, that is, the end of the fan 20 is set as the second end of the cavity structure 10. The cavity structure 10 also includes a third end for arranging a speaker 30, such as Figure 2a and Figure 2bAs shown, the first and second ends of the cavity structure 10 respectively serve as the air inlet 101 and the air outlet 102 of the fan 20, and the third end of the cavity structure 10 is provided with a speaker sound outlet 103. When the speaker 30 is provided at the third end, sound is emitted outward through the speaker sound outlet 103.

[0049] like Figure 1 and Figure 2c As shown, the cavity switching structure 40 is connected to the cavity structure 10, and can be specifically arranged outside the cavity structure 10, and at least part of the cavity switching structure 40 is arranged inside the cavity structure 10 to divide and switch the cavity space inside the cavity structure 10. Specifically, see Figure 5 or Figure 6 The cavity space between the first end, the middle and the second end of the cavity structure 10 can be connected to form a first cavity space 110, which is used as an air duct for the fan 20. The cavity space between the third end and the middle of the cavity structure 10 can be connected to form a second cavity space 120, which is used as a sound channel for the speaker 30. That is, the sound channel capacity is expanded by using the air duct to improve the sound quality performance of the whole machine.

[0050] The cavity switching structure 40 can switch the cavity space inside the cavity structure 10 according to the usage status of the fan 20 and the speaker 30, so that it can switch between the first cavity space 110 and the second cavity space 120. Specifically, when the fan 20 is working, the cavity space inside the cavity structure 10 can be switched to the first cavity space 110, even if the first cavity space 110 is in a connected state, the second cavity space 120 can be in a disconnected state; when the speaker 30 is working, the cavity space inside the cavity structure 10 can be switched to the second cavity space 120, even if the second cavity space 120 is in a connected state, the first cavity space 110 can be in a disconnected state, thereby realizing the linkage switching and cavity sharing of the fan air duct and the speaker sound channel, which can save the space occupied by the structural module in the electronic device.

[0051] Optionally, the cavity structure 10 includes an upper cover 11 and a lower cover 12 , and the upper cover 11 and the lower cover 12 are tightly connected to form an internal cavity space.

[0052] like Figure 3 As shown, the cavity structure 10 includes an upper cover 11 and a lower cover 12, which are tightly fastened together to form a cavity space inside. In order to ensure the airtightness of the internal cavity space to ensure heat dissipation and sound quality, the upper cover 11 and the lower cover 12 can be ensured to be tightly connected, such as by a sealing ring to achieve sealing between the upper cover 11 and the lower cover 12.

[0053] Alternatively, as Figure 3As shown, the cavity common structure 100 also includes at least three lower cover sealing gaskets 13, which are respectively arranged at different positions of the side wall of the lower cover 12. The lower cover sealing gaskets 13 are used to seal the gap between the cavity switching structure 40 and the side wall of the lower cover 12.

[0054] In some embodiments, in order to achieve good sealing between the cavity structure 10 and the cavity switching structure 40, lower cover sealing gaskets 13 can be respectively provided at different side wall positions of the lower cover 12, such as providing at least three lower cover sealing gaskets 13, for example, Figure 5 and Figure 6 Position, a lower cover sealing gasket 13 can be respectively set at several positions where the part of the cavity switching structure 40 extending into the internal space of the cavity structure 10 contacts the side wall of the lower cover 12, that is, a lower cover sealing gasket 13 is set at a lower position near the first end in the middle of the cavity structure 10, a lower cover sealing gasket 13 is set at a left position near the third end in the middle of the cavity structure 10, and a lower cover sealing gasket 13 is set at an upper position near the second end in the middle of the cavity structure 10.

[0055] That is, in this embodiment, the lower cover sealing gasket 13 is disposed in contact with the side wall of the lower cover 12 to achieve sealing between the cavity switching structure 40 , such as the rotating ring 41 , and the side wall of the lower cover 12 .

[0056] Optionally, the speaker 30 is fixedly connected to the third end of the lower cover 12 by glue dispensing; and the fan 20 is fixed to the first end of the lower cover 12 by double-sided tape.

[0057] Specifically, the speaker 30 is a sound-emitting unit, such as Figure 3 As shown, the speaker 30 can be fixed and sealed to the lower cover 12 by dispensing glue 61, and specifically can be fixed to the third end of the lower cover 12 by dispensing glue.

[0058] The fan 20 is an active heat dissipation unit, which can generally be an axial flow fan, such as Figure 3 As shown, the fan 20 can be fixed to the lower cover 12 by the fan double-sided tape 62, specifically, it can be fixed to the first end of the lower cover 12 by the fan double-sided tape 62. That is, the fan double-sided tape 62 is used to securely connect the fan 20 and the lower cover 12.

[0059] Optionally, the cavity switching structure 40 includes a rotating ring 41, and an outwardly protruding segmented baffle 42 is provided on the edge of the rotating ring 41; an annular gap guide rail 121 is provided on the upper cover 11, and the segmented baffle 42 passes through the annular gap guide rail 121 and enters the interior of the cavity structure 10;

[0060] The rotating ring 41 rotates and slides in the annular gap guide rail 121 through the segmented baffle 42 to achieve switching between the first cavity space 110 and the second cavity space 120 of the cavity structure 10.

[0061] In some embodiments, the cavity switching structure 40 can be implemented by using a rotating ring and a baffle structure, such as Figure 1 As shown, the cavity switching structure 40 includes a rotating ring 41 of an annular structure, that is, the rotating ring 41 is a structure that can rotate, such as a ring-shaped part that can rotate around the center axis of the cavity structure 10.

[0062] like Figure 3 and Figure 4 As shown, the edge of the rotating ring 41 is provided with a segmented baffle 42 protruding outward, that is, the segmented baffle 42 is a multi-segment discontinuous baffle, such as including two or more baffles arranged at intervals. The function of the segmented baffle 42 is to seal the cavity space inside the cavity structure 10 or the fan 20 respectively.

[0063] like Figure 4 As shown, the upper cover 11 can also be adapted to be equipped with an annular gap guide rail 121 on the rotating ring 41 structure. The annular gap guide rail 121 can be realized by opening a hole in the upper cover 11, and the segmented baffle 42 can pass through the annular gap guide rail 121 and enter the interior of the cavity structure 10.

[0064] In this way, the rotating ring 41 structure can change the cavity space connected inside the cavity structure 10 by rotating the segmented baffle 42 inside the cavity structure 10, so that it switches between the air duct space and the sound duct space.

[0065] Optionally, the segmented baffle 42 includes a first baffle 421 and a second baffle 422 . The first baffle 421 and the second baffle 422 are arranged opposite to each other, and there is a distance between the first baffle 421 and the second baffle 422 .

[0066] In some embodiments, the segmented baffle 42 may only be a two-segment baffle, such as Figure 4 As shown, the segmented baffle 42 includes a first baffle 421 and a second baffle 422 arranged opposite to each other, and there is a distance between the first baffle 421 and the second baffle 422, that is, the first baffle 421 and the second baffle 422 are arranged at intervals along the outer edge of the rotating ring 41.

[0067] Optionally, the cavity switching structure 40 further includes a rotating ring sealing gasket 43 , which is disposed between the rotating ring 41 and the upper cover 11 . The rotating ring sealing gasket 43 is used to seal the gap between the rotating ring 41 and the upper cover 11 .

[0068] In some embodiments, a rotating ring sealing gasket 43 may be further provided between the rotating ring 41 and the upper cover 11 to achieve a sealed connection between the rotating ring 41 and the upper cover 11 , that is, the rotating ring sealing gasket 43 is used to seal and support the gap between the rotating ring 41 and the upper cover 11 .

[0069] It should be noted that in some embodiments, the rotating ring 41 can be mechanically driven to rotate and switch between the first cavity space 110 and the second cavity space 120. In other embodiments, the rotating ring 41 can also be driven by a motor.

[0070] Optionally, the cavity switching structure 40 also includes a drive motor 50, the two ends of which are respectively connected to the cavity structure 10 and the rotating ring 41, and the drive motor 50 is used to drive the rotating ring 41 to rotate in the annular gap guide rail 121 to switch between the first cavity space 110 and the second cavity space 120.

[0071] That is, in some embodiments, a drive motor 50 may be provided between the cavity structure 10 and the rotating ring 41 , and the cavity structure 10 and the rotating ring 41 are fixedly connected via the drive motor 50 , and the drive motor 50 is used to drive the rotating ring 41 to rotate in different directions.

[0072] Specifically, the drive motor 50 can drive the rotating ring 41 to rotate within the annular slot guide 121, so that when the rotating ring 41 is in different positions, the cavity space inside the cavity structure 10 is in different communication states, thereby switching between the first cavity space 110 and the second cavity space 120. This embodiment can realize electric drive of the rotating ring 41, and the driving method can achieve high efficiency and precision.

[0073] Optionally, a first shaft groove 14 is provided in the middle of the cavity structure 10, a second shaft groove is provided in the middle of the rotating ring 41, and both ends of the driving motor 50 are fixedly connected to the first shaft groove 14 and the second shaft groove respectively through splines.

[0074] That is, in some embodiments, such as Figure 3 and Figure 4 As shown, one end of the main shaft of the drive motor 50 is inserted into the first shaft slot 14 of the lower cover 12, and the other end extends directly from the through hole 111 in the center of the upper cover 11. It is fixedly connected to the center of the rotating ring 41, such as the second shaft slot, via a spline. This enables the main shaft of the drive motor 50 to directly drive the rotating ring 41 to rotate around its axis. The annular slot guide rail 121 on the upper cover 11 is connected to the corresponding opening in the side wall of the lower cover 12. The segmented baffle 42 on the rotating ring 41 can pass through the annular slot guide rail 121 and the corresponding opening in the side wall of the lower cover 12, thereby changing the connectivity of the cavity space within the cavity structure 10.

[0075] Optionally, the rotating ring 41 has two working conditions, wherein:

[0076] When the fan 20 is in operation, the rotating ring 41 is in a first operating state. In the first operating state, the rotating ring 41 rotates to a first position, so that the first cavity space 110 is connected and the second cavity space 120 is disconnected.

[0077] When the speaker 30 is in operation, the rotating ring 41 is in a second operating state. In the second operating state, the rotating ring 41 rotates to a second position, so that the second cavity space 120 is connected and the first cavity space 110 is disconnected.

[0078] That is, in some embodiments, the rotating ring 41 has two working conditions, corresponding to different working states, such as the working state of the fan 20 and the working state of the speaker 30. Under different working conditions, the rotating ring 41 is rotated to different position states, and different position states make the internal cavity space of the cavity structure 10 in different connectivity states.

[0079] For example, Figure 5 As shown, Figure 5 The rotational position state of the rotating ring 41 shown corresponds to working condition 1. At this time, the segmented baffle 42 is inserted into the cavity on one side of the speaker 30. At this time, the air inlet and outlet of the fan 20 air duct are unobstructed. At this time, by reducing the cavity of the speaker 30 and converting it into an air duct, the heat dissipation capacity of the entire machine can be improved.

[0080] like Figure 6 As shown, Figure 6 The rotational position state of the rotating ring 41 shown corresponds to working condition 2. At this time, the segmented baffle 42 is inserted into the cavities on both sides of the air duct, the air inlet and outlet of the air duct are separated and sealed, and the rear wall of the speaker 30 uses the air duct to expand the capacity, which can improve the sound quality performance of the entire machine.

[0081] Optionally, the cavity structure 10 is a T-shaped structure or a cross-shaped structure.

[0082] That is, in some embodiments, the cavity structure 10 may adopt a "T"-shaped layout, such as Figure 1 shown.

[0083] In other embodiments, the cavity structure 10 may also adopt a "cross" layout, that is, Figure 5 and Figure 6 The speaker 30 shown in the figure can also be provided with a cavity expansion on the opposite side of the rotation axis, that is, extending outward on the opposite side of the third end of the cavity structure 10 to expand the cavity, thereby further improving the sound quality of the whole machine.

[0084] In summary, it can be seen that the embodiment of the present application realizes the switching of the two cavities through a single motor and a rotating ring mechanism, realizing a two-in-one design of fan duct + speaker cavity.

In this way, by designing a structure in which the fan and the speaker share a cavity, an integrated module design structure is realized that combines the fan air duct and the speaker sound channel into one. In specific use, the cavity switching structure can be used to control the connection of the first cavity space or the second cavity space according to different working conditions.
