[0047] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0048] An embodiment of the present application provides a terminal device, which may be a mobile phone, a tablet computer, or a laptop computer. For example, the terminal device may include a display screen, or the terminal device may include two display screens. For example, the terminal device may be a dual-screen display device or a folding display device. The terminal device may include: a housing, a first functional panel, and a second functional panel. The first functional panel and the second functional panel in the terminal device may be respectively connected to two opposite sides of the housing. Here, the embodiment of the present application is schematically illustrated by taking the following three optional implementation methods as examples:

[0049] In a first optional implementation, both the first function panel and the second function panel in the terminal device can be display screens. For example, when the terminal device is a dual-screen display device, the first function panel can be a primary display screen provided on the front of the dual-screen display device, and the second function panel can be a secondary display screen provided on the back of the dual-screen display device. When the terminal device is a foldable display device, one of the first function panel and the second function panel can be a foldable display screen, which can serve as the primary display screen of the terminal device; the other of the first function panel and the second function panel can typically be a non-foldable display screen, which can serve as the secondary display screen of the terminal device.

[0050] In a second optional implementation, one of the first and second functional panels in the terminal device may be a display screen, and the other of the first and second functional panels may be a rear cover. In this case, the terminal device may be a device that includes only one display screen.

[0051] In a third optional implementation, one of the first and second function panels in the terminal device can be a primary display, and the other of the first and second function panels can be a rear cover with a secondary display. In this case, the terminal device can be a device with a larger primary display integrated on the front and a smaller secondary display integrated on the back.

[0052] The following embodiments are schematically described by taking the first function panel and the second function panel as display screens and the terminal device as a foldable display device as an example. Here, the terminal device can have a folded state and an unfolded state.

[0053] To see the structure of the terminal device more clearly, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a terminal device when it is unfolded, provided in an embodiment of the present application. Figure 2 The terminal device may include: a housing 100, a first functional panel 200, a second functional panel 300 and a sound component 400 ( Figure 1 and Figure 2 not marked in the table).

[0054] Please refer to Figure 3 , Figure 3 1 is a partial structural diagram of a terminal device provided by an embodiment of the present application, wherein the first function panel 200 and the second function panel 300 in the terminal device 000 can be connected to two opposite sides of the housing 100 respectively.

[0055] Here, when the terminal device 000 is a foldable display device, one of the first function panel 200 and the second function panel 300 can be a foldable display screen, which can serve as the main display screen of the terminal device 000; the other of the first function panel 200 and the second function panel 300 can generally be a non-foldable display screen, which can serve as the secondary display screen of the terminal device 000. It should be noted that this application is schematically described by taking the first function panel 200 as the secondary display screen and the second function panel 300 as the main display screen, that is, the first function panel 200 is a non-foldable display screen and the second function panel 300 is a foldable display screen as an example.

[0056] In this case, the terminal device housing 100 may include: a first housing 101 and a second housing 102, and a hinge 103 for connecting the first housing 101 and the second housing 102. The second function panel 300 may be connected to the first housing 101 and the second housing 102 at the same time, and the first function panel 200 may be connected to a side of the first housing 101 or the second housing 102 facing away from the second function panel 300.

[0057] The sound producing component 400 in the terminal device 000 may be fixed inside the housing 100. The sound producing component 400 may have a first vibration cavity 400a and a second vibration cavity 400b arranged opposite to each other, and the sound producing component 400 may produce sound through the first vibration cavity 400a and the second vibration cavity 400b.

[0058] The sound producing component 400 in the terminal device 000 may further include a first sound output channel 400c in communication with the first vibration cavity 400a. The end of the first sound output channel 400c facing away from the first vibration cavity 400a may face the first functional panel 200. Here, the first sound output channel 400c in the sound producing component 400 may be used to transmit the audio output from the first vibration cavity 400a.

[0059] The side of the shell 100 in the terminal device 000 where the second functional panel 300 is set may have a second sound output channel 400d connected to the second vibration cavity 400b, wherein the second sound output channel 400d can be used to transmit the audio output in the second vibration cavity 400b.

[0060] It should be noted that the pronunciation component 400 in this application can be used as a handset in the terminal device 000.

[0061] In the present application, since the sound producing component 400 has a first sound output channel 400c connected to the first vibration cavity 400a, and the side of the housing 100 where the second function panel 300 is provided has a second sound output channel 400d connected to the second vibration cavity 400b, when the terminal device 000 is in the unfolded state and the user holds the terminal device 000 to answer a call or receive a voice message, the second function panel 300 can face the user's face. In this state, the end of the second sound output channel 400d that is away from the second vibration cavity 400b can be close to the user's ear, so that the sound emitted by the sound producing component 400 through the second vibration cavity 400b can be transmitted to the user's ear through the second sound output channel 400d, so that the user can answer a call or receive a voice message through the terminal device 000 in the unfolded state.

[0062] When the terminal device 000 is in a folded state and the user holds the terminal device 000 to answer a call or receive a voice message, the first function panel 200 can be facing the user's face. In this state, the end of the first sound output channel 400b facing away from the first vibration cavity 400a can be close to the user's ear, so that the sound emitted by the pronunciation component 400 through the first vibration cavity 400a can be transmitted to the user's ear through the first sound output channel 400b, so that the user can answer a call or receive a voice message through the terminal device 000 in a folded state.

[0063] In this way, when the user uses the terminal device 000 to answer a call or receive a voice message, whether the terminal device 000 is in a folded state or an unfolded state, the sound emitted by the sound component 400 can be better transmitted to the user's ears, so that the sound output effect of the sound emitted by the sound component 400 is better, thereby improving the reliability of this terminal device 000. In addition, because the sound component 400 has a first vibration cavity 400a and a second vibration cavity 400b that are relatively arranged, the same sound component 400 can transmit sound to the user's ears when the terminal device 000 is in a folded state, and can also transmit sound to the user's ears when the terminal device 000 is in an unfolded state. In this way, without increasing the number of components in the terminal device 000, the reliability of this terminal device 000 is guaranteed to be high.

[0064] In summary, a terminal device provided by an embodiment of the present application includes: a shell, a first functional panel, a second functional panel and a sound producing component. Since the sound producing component has a first sound output channel connected to the first vibration cavity, and the side of the shell where the second functional panel is provided has a second sound output channel connected to the second vibration cavity. Therefore, in the process of the user using the terminal device to answer a call or receive a voice message, whether the terminal device is in a folded state or an unfolded state, the sound emitted by the sound producing component can be better transmitted to the user's ear, so that the sound output effect of the sound emitted by the sound producing component is better, thereby improving the reliability of the terminal device. In addition, since the sound producing component has a first vibration cavity and a second vibration cavity that are relatively arranged, the same sound producing component can transmit sound to the user's ear when the terminal device is in a folded state, and can also transmit sound to the user's ear when the terminal device is in an unfolded state. In this way, without increasing the number of components in the terminal device, the reliability of the terminal device is guaranteed to be high.

[0065] In the examples of this application, please refer to Figure 4 , Figure 4The sound generating assembly 400 in the terminal device 000 may include a device core 401 and a support shell 402 connected to a side of the device core 401 facing away from the second functional panel 300 .

[0066] Among them, the side of the device core 401 in the sounding component 400 facing the supporting shell 402 can have a first vibration cavity 400a between it and the supporting shell 402, and the side of the device core 401 away from the supporting shell 402 can have a second vibration cavity 400b between it and the second functional panel 300.

[0067] For example, please refer to Figure 5 and Figure 6 , Figure 5 This is a structural diagram of a pronunciation component provided in an embodiment of the present application. Figure 6 yes Figure 5 The support shell 402 in the sounding assembly 400 may include: a support shell body 4021 fixedly connected to one side of the device core 401 , and a sealing metal sheet 4022 fixedly connected to the support shell body 4021 .

[0068] The sealing metal sheet 4022 in the support shell 402 can cover the device core 401, and the sealing metal sheet 4022, the support shell body 4021, and one side of the device core 401 can be used to enclose a first vibration cavity 400a. Here, the device core 401 has a first diaphragm 401a on the side facing the sealing metal sheet 4022. The first vibration cavity 400a of the sounding component 400 can be located between the first diaphragm 401a and the sealing metal sheet 4022. The first diaphragm 401a of the device core 401 can vibrate within the first vibration cavity 400a, so that sound can be emitted within the first vibration cavity 400a.

[0069] In this application, please refer to Figure 4 、 Figure 7 and Figure 8 , Figure 7 This is a schematic structural diagram of a housing provided in an embodiment of the present application. Figure 8It is a partial exploded view of a terminal device provided in an embodiment of the present application. The shell 100 in the terminal device 000 may have a side frame 101 and a bottom plate 102. Among them, the side frame 101 can be fixedly connected to the bottom plate 102, one side of the side frame 101 is used to connect to the first functional panel 200, and the other side of the side frame 101 is used to connect to the second functional panel 300. The pronunciation component 400 in the terminal device 000 can be assembled in the accommodating space surrounded by the side frame 101, the first functional panel 200 and the bottom plate 102. Here, the supporting body 4021 in the supporting shell 402 in the pronunciation component 400 can be fixedly connected to the shell 100 in the terminal device 000, and the sealing metal sheet 4022 in the supporting shell 402 is further away from the bottom plate 102 relative to the device core 401.

[0070] Optionally, the portion of the bottom plate 102 in the housing 100 connected to the sound generating assembly 400 has an opening S that matches the device core 401. At least a portion of the side of the device core 401 facing away from the supporting shell 401 can be exposed through the opening S.

[0071] Here, the device core 401 has a second vibration membrane 401b on the side facing away from the supporting shell 401, and the second vibration membrane 401b can be exposed through the opening S set on the base plate 102. The second vibration cavity 400b of the sound-producing component 400 can be located between the second vibration membrane 401b and the second functional panel 300, and the second vibration membrane 401b of the device core 401 can vibrate in the second vibration cavity 400b, so that sound can be emitted in the second vibration cavity 400b.

[0072] For example, Figure 4 and Figure 8 As shown, the terminal device 000 may further include: a sealing strip 500 located between a side of the device core 401 in the sounding component 400 facing away from the supporting shell 402 in the sounding component 400 and the second functional panel.

[0073] The sealing strip 500, the housing 100, the side of the device core 401 facing away from the support shell 402, and the second functional panel 300 are used to enclose a second vibration cavity 400b. The sealing strip 500 can be fixed to the back of the second functional panel 300 by bonding, where the back of the second functional panel 300 refers to the side opposite the display surface of the second functional panel 300. The side of the sealing strip 500 facing away from the second functional panel 300 can abut against the side of the bottom plate 102 in the housing 100 facing away from the sound component 400. The sealing strip 500 can also enclose a space with an auxiliary gap Z between the bottom plate 101 and the second functional panel 300. The space enclosed by the sealing strip 500 on the bottom plate 101 and the second functional panel 300 is the second vibration cavity 400b. The second sound output channel 400d, located on the side of the housing 100 where the second functional panel 300 is located, can communicate with the second vibration cavity 400b through this auxiliary gap Z.

[0074] For examples, please refer to Figure 9 , Figure 9 It is a structural schematic diagram of the other side of a shell provided by an embodiment of the present application. The shell 100 may also include: a screen pressing strip 103 fixedly connected to the side of the side frame 101 facing the second functional panel 300. The screen pressing strip 103 can cover the edge portion of the second functional panel 300, so that the second functional panel 300 can be assembled on the side of the shell 100 away from the first functional panel 200 through the screen pressing strip 103 and the side frame 101. Here, the screen pressing strip 103 in the shell 100 can have a second sound outlet channel 400d, and the two ends of the auxiliary notch Z provided in the sealing strip 500 can be respectively distributed on both sides of the second sound outlet channel 400d provided in the screen pressing strip 103, so that the second sound outlet channel 400d provided on the screen pressing strip 103 can be connected to the second vibration cavity 400b through this auxiliary notch Z.

[0075] In this application, if Figure 5 and Figure 6 As shown, the supporting shell 402 in the sound producing assembly 400 may have a third sound outlet channel 402a communicating with the first vibration cavity 400a, and a sound outlet opening A distributed on the side of the third sound outlet channel 402a away from the first vibration cavity 400a.

[0076] The sound producing component 400 in the terminal device 000 may further include an extension portion 403 connected to the supporting shell 402. At least a portion of the extension portion 403 in the sound producing component 400 may be distributed at the sound outlet opening A, and the extension portion 403 may have a first sound outlet channel 400c. Here, the first sound outlet channel 400c may be connected to the third sound outlet channel 402a through the sound outlet opening A. In this way, when the device core 401 in the sound producing component 400 produces sound through the first vibration cavity 400a, the sound generated in the first vibration cavity 400a may be transmitted in sequence through the third sound outlet channel 402a and the first sound outlet channel 400c.

[0077] In the examples of this application, please refer to Figure 5 and Figure 6 The extension portion 403 in the sound producing component 400 may include: a first sub-extension portion 4031 distributed at the sound outlet opening A, and a second sub-extension portion 4032 fixedly connected to the first sub-extension portion 4031 .

[0078] Here, the first sub-extension portion 4031 in the extension portion 403 may include a first sub-channel 4031a connected to the third sound output channel 402a, and the second sub-extension portion 4032 in the extension portion 403 may include a second sub-channel 4032a connected to the first sub-channel 4031a. The extension direction of the first sub-channel 4031a may intersect with the extension direction of the second sub-channel 4032a, and the first sound output channel 400c may include the first sub-channel 4031a and the second sub-channel 4032a. In this case, since the first sound output channel 400c includes the first sub-channel 4031a and the second sub-channel 4032a whose extension directions intersect, when the device core 401 in the sound producing component 400 makes a sound through the first vibration cavity 400a, the sound generated in the first vibration cavity 400a can change the sound transmission direction in the process of being transmitted through the third sound output channel 402a, the first sub-channel 4031a and the second sub-channel 4032a in sequence, so that the sound generated in the first vibration cavity 400a can be transmitted along the side toward the first functional panel 200.

[0079] Optional, such as Figure 4 、 Figure 7 and Figure 8As shown, the edge area of ​​the first function panel 200 in the terminal device 000 may have a first opening K1. Here, if the first function panel 200 is a display screen, the edge area of ​​the first function panel 200 in the terminal device 000 may be the non-display area of ​​the display screen. The end of the second sub-extension 4032 facing away from the first sub-extension 4031 may be located within the first opening K1. In this case, when the terminal device 000 is folded and a user holds the terminal device 000 to answer a call or receive a voice message, the user can place their ear close to the first opening K1 in the first function panel 200, allowing the user to hear the sound emitted by the second sub-channel 4032a of the second sub-extension 4032. Furthermore, the provision of the first opening K1 in the edge area of ​​the first function panel 200 ensures that the first opening K1 does not affect the display quality of the first function panel 200.

[0080] In this application, please refer to Figure 7 The side of the shell 100 in the terminal device 000 where the first functional panel 200 is set may have a second opening K2 connected to the first opening K1, and the end of the second sub-extension 4032 away from the first sub-extension 4031 can be distributed in the first opening K1 after passing through the second opening K2.

[0081] For example, the side frame 101 of the housing 100 facing the first functional panel 200 may have a second opening K2. The end of the second sub-extension 4032 facing away from the first sub-extension 4031 passes through the second opening K2 provided in the side frame 101 and then is disposed within the first opening K1 provided in the edge region of the first functional panel 200. This ensures that the second sub-extension 4032 can be disposed not only within the first opening K1 provided in the edge region of the first functional panel 200, but also within the second opening K2 provided in the side frame 101 of the housing 100. This improves the stability of the second sub-extension 4032 when mated with the first functional panel 200.

[0082] Optional, such as Figure 10 As shown, Figure 10 yes Figure 7The schematic structural diagram of the shell shown in another perspective shows that the shell 100 in the terminal device 000 may also have a bearing groove U connected to the second opening K2, and at least a portion of the first sub-extension 4031 in the extension 403 may be located in the bearing groove U. For example, the side frame 101 in the shell 100 may have a bearing groove U connected to the second opening K2. In this way, after at least a portion of the first sub-extension 4031 in the extension 403 is located in this bearing groove U, it is more convenient to allow the second sub-extension 4032 in the extension 403 to turn away from the first sub-extension 4031 and pass through the second opening K2 provided on the side frame 101. This bearing groove U can also prevent the sound assembly 400 from being unable to be properly assembled with the shell 100 due to the additional extension 403 provided in the sound assembly 400.

[0083] In the examples of this application, please refer to Figure 4 and Figure 7 The housing 100 in the terminal device 000 may further include a fourth sound outlet channel 100a. For example, the side frame 101 in the housing 100 may include a fourth sound outlet channel 100a.

[0084] The sound producing component 400 in the terminal device 000 may further include: an annular abutting portion 404 fixedly connected to the extension portion 403. The abutting portion 404 in the sound producing component 400 may be distributed between the shell 100 and the supporting shell 402 in the sound producing component 400, and one side of the area enclosed by the abutting portion 404 in the sound producing component 400 may be connected to the fourth sound output channel 100a, and the other side may be connected to the third sound output channel 402a. In this way, the sound emitted by the sound producing component 400 through the first vibration cavity 400a can not only be transmitted sequentially through the third sound output channel 402a and the first sound output channel 402a, but can also be transmitted sequentially through the third sound output channel 402a, the area enclosed by the abutting portion 404, and the fourth sound output channel 100a.

[0085] In this case, the sound producing component 400 can be used not only as an earpiece in the terminal device 000 , but also as a speaker in the terminal device 000 .

[0086] For example, when the pronunciation component 400 is used as a handset in the terminal device 000, when the terminal device 000 is in a folded state and the user holds the terminal device 000 to answer a call or receive a voice message, the first function panel 200 can be facing the user's face. In this state, the sound emitted by the pronunciation component 400 through the first vibration cavity 400a can be directly transmitted to the user's ear through the first sound output channel 400b. At the same time, the sound emitted by the pronunciation component 400 through the second vibration cavity 400b can be transmitted to directions other than the direction of the human ear through the second sound output channel 400d, and another part of the sound emitted by the pronunciation component 400 through the first vibration cavity 400a can be transmitted to directions other than the direction of the human ear through the fourth sound output channel 100a. Here, the sound transmitted through the second sound output channel 400d and the fourth sound output channel 100a can be used to offset the noise in the environment.

[0087] When the terminal device 000 is in the unfolded state and the user holds the terminal device 000 to answer a call or receive a voice message, the second function panel 300 can be facing the user's face. In this state, the sound emitted by the pronunciation component 400 through the second vibration cavity 400b can be directly transmitted to the user's ear through the second sound output channel 400d. At the same time, the sound emitted by the pronunciation component 400 through the first vibration cavity 400a can be transmitted to other directions except the direction of the human ear through the first sound output channel 400d and the fourth sound output channel 100a. Here, the sound transmitted through the first sound output channel 400d and the fourth sound output channel 100a can be used to offset the noise in the environment.

[0088] When the sound component 400 is used as a speaker in the terminal device 000, the sound emitted by the sound component 400 through the first vibration cavity 400a can be transmitted through the first sound output channel 400b and the fourth sound output channel 100a, and the sound emitted by the sound component 400 through the second vibration cavity 400b can be transmitted through the second sound output channel 400d. In this case, whether the terminal device 000 is in a folded state or an unfolded state, the sound emitted by the sound component 400 can be better transmitted in all directions, so that the sound output effect of the sound component 400 is better.

[0089] In this application, please refer to Figure 11 , Figure 11 4 is a schematic diagram of the structure of an extension portion and an abutting portion provided in an embodiment of the present application. The first sub-extension portion 4031 of the extension portion 403 can be distributed within the area surrounded by the abutting portion 404, and the second sub-extension portion 4032 of the extension portion 403 can be distributed outside the area surrounded by the abutting portion 404. Here, the first sub-extension portion 4031 and the second sub-extension portion 4032 of the extension portion 403 can both be fixedly connected to the abutting portion 404.

[0090] In one possible implementation, the abutment portion 404 and the extension portion 403 in the sound output component 400 can be an integrated structure. For example, the abutment portion 404 and the extension portion 403 in the sound output component 400 can be an integrated structure formed by a one-time injection molding process, and the material of the integrated structure can use sealing silicone. In this way, not only can the high firmness of the connection between the extension portion 403 and the abutment portion 404 be ensured, but also the side of the support shell 402 in the sound output component 400 on which the third sound output channel 402a is provided can be more firmly abutted against the side frame 101 in the shell 100 through this integrated structure, so that the dust and moisture that invade from the fourth sound output channel 100a provided on the side frame 101 can be blocked by this integrated structure, thereby preventing these dust and moisture from invading the interior of the shell 100, further improving the reliability of the terminal device 000.

[0091] In the embodiments of this application, Figure 5 and Figure 11 As shown, the abutting portion 404 in the sounding assembly 400 may include an abutting protrusion 4041 and an annular main body 4042. The main body 4042 in the abutting portion 404 may be connected to the supporting shell 402 at the sound outlet opening A, the abutting protrusion 4041 in the abutting portion 404 may be connected to a side of the main body 4042 facing away from the supporting shell 402, and the side of the abutting protrusion 4041 facing away from the main body 4042 may abut against the housing 100.

[0092] For example, the side of the abutting protrusion 4041 in the abutting portion 404 facing away from the main body 4042 can abut against the side frame 101 in the housing 100. Because the abutting portion 404 and the extension portion 403 are integrally formed and both are made of sealing silicone, the abutting protrusion 4041 can deform to a certain extent after abutting against the side frame 101. In this way, dust and moisture entering through the fourth sound output channel 100a provided on the side frame 101 can be blocked by the deformed abutting protrusion 4041, ensuring that such dust and moisture do not enter the interior of the housing 100.

[0093] In this application, if Figure 5 and Figure 11As shown, the abutting protrusion 4041 in the abutting portion 404 can be in the form of an annular strip with a notch. The main body 4041 in the abutting portion 404 can be fixedly connected to the extension portion 403, and the portion of the extension portion 403 located between the first sub-extension portion 4031 and the second sub-extension portion 4032 can be located at the notch. The abutting portion 404 in the sounding assembly 400 can also include an auxiliary abutting protrusion 4043 fixedly connected to the extension portion 403. Here, the auxiliary abutting protrusion 4043 can be located between the first sub-extension portion 4031 and the second sub-extension portion 4032, and the two ends of the auxiliary abutting protrusion 4043 can be fixedly connected to the two ends of the abutting protrusion 4041 at the notch, respectively. The side of the auxiliary abutting protrusion 4043 facing away from the abutting protrusion 4041 can abut against the housing 100. Here, the auxiliary abutting protrusion 4043 and the abutting protrusion 4041 can form a closed annular structure.

[0094] In this case, after the sound assembly 400 is assembled inside the housing 100, the auxiliary abutting protrusion 4043 located between the first sub-extension portion 4031 and the second sub-extension portion 4032 can be distributed within the bearing groove U provided on the side frame 101, and at least a portion of the auxiliary abutting protrusion 4043 can abut against the inner wall of the bearing groove U. Furthermore, because the abutting portion 404 and the extension portion 403 are integrally formed and both are made of sealing silicone, after the sound assembly 400 is assembled inside the housing 100, not only the abutting protrusion 4041 abutting against the side frame 101 can be deformed to a certain extent, but also the auxiliary abutting protrusion 4043 located within the bearing groove U can be deformed to a certain extent. In this way, dust and moisture invading from the fourth sound outlet channel 100a set on the side frame 101 can be blocked by the abutment protrusion 4041 and the auxiliary abutment protrusion 4043 in the deformed state, and the abutment protrusion 4041 and the auxiliary abutment protrusion 4043 can be assembled into a closed annular structure, thereby ensuring that these dust and moisture will not enter the interior of the shell 100 from all directions.

[0095] In the examples of this application, please refer to Figure 4 、 Figure 5 and Figure 6The sound output component 400 in the terminal device 000 may further include: a sealing member 405 distributed between the main body 4042 in the abutting portion 404 and the supporting shell 402. The sealing member 405 in the sound output component 400 may be fixedly connected to a side of the supporting shell 402 in the sound output component 400 where the sound output opening A is provided, and the sealing member 405 may cover the sound output opening A. The side of the sealing member 405 in the sound output component 400 that faces away from the supporting shell may be fixedly connected to the main body 4042 in the abutting portion 404. In this way, dust and moisture that invade from the fourth sound output channel 100a provided on the side frame 101 may be blocked by the sealing member 405 in the sound output component 400, so that the dust and moisture will not penetrate into the device core 401 in the sound output component 400 through the sound output opening A, thereby reducing the risk of damage to the sound output component 400 due to the entry of dust and moisture.

[0096] In summary, a terminal device provided by an embodiment of the present application includes: a shell, a first functional panel, a second functional panel and a sound producing component. Since the sound producing component has a first sound output channel connected to the first vibration cavity, and the side of the shell where the second functional panel is provided has a second sound output channel connected to the second vibration cavity. Therefore, in the process of the user using the terminal device to answer a call or receive a voice message, whether the terminal device is in a folded state or an unfolded state, the sound emitted by the sound producing component can be better transmitted to the user's ear, so that the sound output effect of the sound emitted by the sound producing component is better, thereby improving the reliability of the terminal device. In addition, since the sound producing component has a first vibration cavity and a second vibration cavity that are relatively arranged, the same sound producing component can transmit sound to the user's ear when the terminal device is in a folded state, and can also transmit sound to the user's ear when the terminal device is in an unfolded state. In this way, without increasing the number of components in the terminal device, the reliability of the terminal device is guaranteed to be high.
