Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies, and in particular to a terminal device. Background Art

[0002] As the functions of electronic devices, such as mobile phones, continue to diversify, multiple devices for implementing different functions are integrated into the mobile phones.

[0003] Existing terminal equipment can be Figure 2a 、 Figure 3 As shown, a plurality of devices are provided in the top area of ​​the terminal device, such as a front camera module 6, etc. The front camera module 6 is located in the middle of the screen, and the sound hole 103 itself is symmetrical with respect to the center line of the screen. Therefore, in the internal space of the terminal, the speaker 101 is eccentrically designed, resulting in unbalanced sound on both sides of the sound hole 103. Among them, the sound hole 103 close to the side of the speaker 101 has a better sound effect, and the sound hole 103 away from the side of the speaker 101 has a poor sound effect.

[0004] However, when a user uses a terminal device, the postures for answering a call include holding the mobile terminal with the left hand to the left ear or holding the mobile terminal with the right hand to the right ear. In either posture, the ear will block part of the sound outlet, and the sound emitter 101 can only emit sound through the unblocked area of ​​the sound outlet 103. When the user blocks the sound outlet on the side with better sound output, the sound output will be poor, affecting the user experience. Summary of the Invention

[0005] The embodiment of the present application provides a terminal device that solves the problem of poor sound quality of the terminal device.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: the present application provides a terminal device, comprising a display module, a sound emitter and a middle frame; the display module is mounted on the middle frame, and the sound emitter is located on the side of the middle frame away from the display module; the terminal device is also provided with a first sound hole group and a second sound hole group, and the first sound hole group and the second sound hole group are arranged between the top of the terminal device and the sound emitter; the first sound hole group is located on the first side of the center of the top of the terminal device, the sound emitter is located on the first side of the terminal device, and the sound emitter is opposite to the position of the first sound hole group, and the second sound hole group is located at The second side of the center of the top of the terminal device; the speaker is fixed to the middle frame through a bracket, and the middle frame is provided with a first through hole and a second through hole; the bracket is provided with a first groove, the first groove is close to the middle frame, and the first groove includes a first groove section, a second groove section, and a third groove section; the first groove section and the first through hole are opposite to the first sound hole group, and the speaker is connected to the first sound hole group through the first groove section; the second groove section and the second through hole are opposite to the second sound hole group, and the third groove section is located between the first groove section and the second groove section; the speaker is connected to the second sound hole group through the first groove and the second through hole. As a result, the speaker is connected to the second sound hole group through the first groove and the second through hole, so that the speaker can effectively transmit the sound through the first groove and the second through hole to the second sound hole group farther away from the speaker, so that the sound emitted by the sound hole groups at different positions is more balanced, avoiding poor sound caused by blocking one side of the sound hole when the user answers the call, thereby improving the user experience.

[0007] In an optional implementation, the terminal device also includes a front camera module, which is located in the middle of the top of the screen, the first groove is located between the front camera module and the top of the terminal device, the first through hole and the second through hole are located between the front camera module and the top of the terminal device, and the third groove section is opposite to the front camera module. Thus, the first groove is arranged between the front camera module and the top of the terminal device, and can serve as a bridge to bypass the bottleneck position between the camera module and the sound hole group, thereby improving the effect of the sound emitted from the sound hole group. At the same time, compared with being set at other positions, the distance from the second sound hole group is shorter, which can better guide the sound to the second sound hole group.

[0008] In an optional implementation, the first through hole and the second through hole are not connected on the middle frame, thereby improving the effect of the sound emitted from the second sound outlet hole group.

[0009] In an optional implementation, a second groove is provided on the middle frame, connecting the first through-hole and the second through-hole, and the second groove is positioned opposite the front camera module. Thus, the provision of the second groove adds a sound channel, allowing the sound source to communicate through the first groove section, the first through-hole, the second groove, and the second sound hole group, further enhancing the sound effect emitted from the second sound hole group.

[0010] In an optional implementation, the middle frame is provided with a third through-hole, which connects the second groove and the third groove segment. Thus, the second groove and the third groove segment are directly connected through the oblique hole, making the sound cavity channel larger and further improving the effect of the sound emitted from the second sound hole group.

[0011] In an optional implementation, the second groove and the third groove section are not connected in the vertical direction. Thus, there is no need to open an oblique hole on the middle frame, the sound cavity channel has a better sealing effect, and the sound can be better directed to the second sound hole group.

[0012] In one optional implementation, the electronic device further includes a third sound hole group, the third sound hole group being opposite the second groove, the third sound hole group being located between the first sound hole group and the second sound hole group, and the third sound hole group being connected to the second groove. Thus, when the second groove is connected to the sound source, the sound emitted by the sound source can also be directed to the third sound hole group through the second groove, thereby adding a sound channel and improving the sound output effect of the sound hole group.

[0013] In an optional implementation, the first sound outlet hole group, the second sound outlet hole group, and the third sound outlet hole group each include one or more sound outlet holes, and the sound outlet holes are circular, square, etc. Thus, the shape of the sound outlet holes is more flexible.

[0014] In an optional implementation, the first sound outlet hole group, the second sound outlet hole group, and the third sound outlet hole group form one sound outlet hole, thereby simplifying the sound outlet hole structure.

[0015] In an optional implementation, the first sound hole group, the second sound hole group, and the third sound hole group are arranged on the middle frame, thereby making the positions of the sound hole groups more flexible.

[0016] In an optional implementation, a cover plate is provided on the surface of the display module away from the middle frame, and the first sound hole group, the second sound hole group, and the third sound hole group are provided on the cover plate. Thus, the positions of the sound hole groups are more flexible.

[0017] In an optional implementation, a bracket is provided to replace the bracket in the first aspect described above, wherein a first slot section, a second slot section, and a third through hole are provided on the bracket, wherein the third through hole connects the first slot section and the second slot section; the first slot section and the first through hole are opposite to the first sound hole group, and the speaker connects to the first sound hole group via the first slot section and the first through hole; the second slot section and the second through hole are opposite to the second sound hole group; the speaker connects to the second sound hole group via the first slot section, the third through hole, the second slot section, and the second through hole. Thus, the speaker connects to the second sound hole group via the first slot section, the third through hole, the second slot section, and the second through hole on the bracket, so that the speaker can transmit sound to the second sound hole group farther away from the speaker, making the sound emitted by the sound hole groups at different positions more balanced, avoiding poor sound caused by blocking one side of the sound hole when the user answers a call, thereby improving the user experience.

[0037] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0038] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0039] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0040] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0041] The embodiments of the present application provide a terminal device. The terminal device can be a product with a display interface such as a tablet computer, a mobile phone, an e-reader, a remote control, a personal computer (PC), a laptop computer, a personal digital assistant (PDA), a vehicle-mounted device, an Internet TV, a wearable device, a television, as well as smart display wearable products such as smart watches and smart bracelets. The embodiments of the present application do not impose any special restrictions on the specific form of the above-mentioned terminal device. For the sake of convenience of explanation, the following embodiments are all illustrated by taking the terminal device as an example of a mobile phone.

[0042] like Figure 1 As shown, the terminal device 1 includes a display module 2, a middle frame 3, a shell (or battery cover, back shell) 4 and a cover plate 5.

[0043] The display module 2 has a light-emitting surface a1 through which the display image can be seen and a back surface a2 opposite to the light-emitting surface a1 . The back surface a2 of the display module 2 is close to the middle frame 3 , and the cover plate 5 is arranged on the light-emitting surface a1 of the display module 2 .

[0044] In a possible embodiment of the present application, the display module 2 is a liquid crystal display (LCD).

[0045] In another possible embodiment of the present application, the display module 2 is an organic light emitting diode (OLED) display module. Since each light-emitting sub-pixel in the OLED display module is provided with an electroluminescent layer, the OLED display module can achieve self-luminescence after receiving an operating voltage.

[0046] The cover plate 5 is located on a side of the display module 2 away from the middle frame 3 . The cover plate 5 may be, for example, a cover glass (CG), which may have a certain toughness.

[0047] The middle frame 3 is located between the display module 2 and the housing 4. The surface of the middle frame 3 facing away from the display module 2 is used to mount internal components such as the battery, printed circuit board (PCB), camera, and antenna. When the housing 4 and middle frame 3 are closed, these internal components are located between the housing 4 and the middle frame 3.

[0048] The middle frame 3 includes, for example, a carrying plate 301 and a frame 302 surrounding the carrying plate 301. In some embodiments, the frame 302 may be an integral frame formed on the carrying plate 301.

[0049] The cover plate 5 is, for example, disposed above the display module 2 and connected to the frame 302 of the middle frame 3 .

[0050] See also Figure 1 The surface of the carrier plate 301 facing the housing 4 can be equipped with a printed circuit board (PCB), a camera, a battery, and other electronic components. The camera and battery are not shown in the figure. The housing 4 is connected to the middle frame 3 to form a cavity for accommodating the PCB, camera, battery, and other electronic components. This prevents external moisture and dust from intruding into the cavity and affecting the performance of the electronic components.

[0051] The display module 2 can be electrically connected to a PCB disposed on the carrier board 301 through a flexible printed circuit (FPC) passing through the carrier board 301. In this way, the PCB can transmit display data to the display module 2 to control the display module 2 to display images.

[0052] The display module 2, the middle frame 3 and the housing 4 can be arranged in different layers in the thickness direction of the electronic device. These layers can be parallel to each other. The plane where each layer is located can be called the XY plane, and the direction perpendicular to the XY plane can be called the Z direction. In other words, the display module 2, the middle frame 3 and the housing 4 can be layered in the Z direction. Figure 1 shown.

[0053] On this basis, if Figure 2a As shown, the terminal device 1 further includes a front camera module 6. The front camera module 6 is arranged on the back side a2 of the display module 2 opposite to the light-emitting surface a1, and the light-receiving surface of the front camera module 6 faces the display module 2. The front camera module 6 can be electrically connected to the PCB board.

[0054] The front camera module 6 is a component that includes a light sensor. For example, the front camera module 6 may include one or more of a front camera, a fingerprint sensor, a proximity light sensor, a time of flight (TOF) sensor, an iris recognition sensor, or a face recognition sensor. The front camera module 6 can be used to capture images of the side of the display surface of the terminal device 1.

[0055] This embodiment does not limit the front camera module 6, as long as the camera module located inside the terminal device can use an electronic sensor to convert optical images into electronic data.

[0056] The camera module includes a lens for inputting light into the front camera module 6, so that the front camera module 6 can convert the light into a digital signal capable of forming an image through an imaging element. The lens can collect light outside the display module through the hollow area on the display module 2, so that the camera module can capture images.

[0057] Regarding the setting area of ​​the front camera module 6, Figure 2a As shown, the display module 2 divides the display area into a boundary A.

[0058] In a possible embodiment, the display module 2 further includes a cover plate boundary B located around the display area boundary A.

[0059] In another possible embodiment, a terminal device boundary C is provided around the cover plate boundary B, and the middle frame 3 may be located between the terminal device boundary C and the cover plate boundary B.

[0060] The relative positional relationship and shape of the display area boundary A and the cover plate boundary B are not limited. In the embodiment of the present application, the cover plate boundary B is taken as an example to surround the display area boundary A.

[0061] It is understandable that the front camera module 6 included in the terminal device 1 realizes a specific function by collecting light that passes through the display module 2 and is directed to the front camera module 6. The display module 2 transmits light through the area surrounded by the display area boundary A. Figure 2a As shown, the orthographic projection of the front camera module 6 on the display module 2 is located within the area enclosed by the display area boundary A of the display module 2. Optionally, the orthographic projection of the front camera module 6 can also be located outside the area enclosed by the display area boundary A of the display module 2, such as in the case of a water drop screen or a notch screen.

[0062] For example, Figure 2b As shown, the terminal device adopts a notch screen, and the camera module is set in the notch area of ​​the screen.

[0063] The following is a hole-punch screen ( Figure 2a ) terminal device as an example to describe the setting method of the sound cavity.

[0064] like Figure 3 、 Figure 4 As shown, the terminal device further includes: a sound output device 10.

[0065] The sound emitting device 10 at least comprises: a sound emitter 101, a sound cavity channel 102 and a sound outlet 103. In this embodiment, Figure 5 As shown, the sound emitter 101 can be an earpiece or a loudspeaker.

[0066] The embodiment of the present application does not limit the specific position of the sound outlet 103 .

[0067] like Figure 3 As shown, the sound outlet 103 shown in this embodiment is arranged on the middle frame 3 between the cover plate boundary B and the terminal device boundary C.

[0068] In other embodiments, the sound outlet 103 may also be provided on the cover plate 5 between the display area boundary A and the cover plate boundary B.

[0069] In other embodiments, the sound hole 103 may also be partially set on the middle frame 3 between the cover plate boundary B and the terminal device boundary C, and the other part may be set on the cover plate 5 between the display area boundary A and the cover plate boundary B.

[0070] These configurations all fall within the protection scope of this application.

[0071] This embodiment does not limit the specific shape of the sound outlet 103. In some embodiments, Figure 3 As shown, the sound outlet holes 103 are a plurality of circular hole structures.

[0072] In other embodiments, Figure 4 As shown, there is one sound outlet hole 103, which may be in a long strip structure.

[0073] In other embodiments, the sound outlet 103 may also be in an elliptical, square, or irregular shape, etc., all of which fall within the scope of protection of this application.

[0074] like Figure 3 、 Figure 4 As shown, the two sides of the sound hole 103 are symmetrical along the vertical center line of the terminal device (it can be understood that the vertical center line is parallel to the Y direction, and in actual products, the symmetry can have a certain range of errors), so that the setting method of the sound hole 103 shown in this embodiment is adopted, so that when the user uses the terminal device, the sound hole 103 can be set directly opposite the user's ear, which can improve the effect of the sound emitted by the sound hole 103 and enable the user to hear a more balanced sound effect through the evenly arranged sound holes 103.

[0075] See next Figure 3 、 Figure 4, the sound hole 101 includes, for example: a first sound hole group 1031, a second sound hole group 1032 and a third sound hole group 1033. The first sound hole group 1031, the second sound hole group 1032 and the third sound hole group 1033 can be different parts of a sound hole, or each sound hole group includes at least one sound hole. The first sound hole group 1031 is opposite to the sound emitter 101, and the third sound hole group 1033 is opposite to the front camera module 6. The sound emitter 101 is located on one side of the front camera module 6, and the second sound hole group 1032 is located on the other side of the front camera module 6 (the side away from the sound emitter 101). The first sound hole group 1031 and the second sound hole group 1032 are symmetrical along the vertical center line of the front camera module 6. The vertical center line of the front camera module 6 and the vertical center line of the terminal device can be the same center line.

[0076] The sound cavity channel 102 is provided inside the middle frame 3 and is located below the display module 2 in the Z direction. The sound cavity channel 102 is used to connect the sound outlet 102 and the sound emitter 101 .

[0077] Specifically, the sound cavity channel 102 is used to guide the sound emitted by the sound emitter 101 to the sound outlet 103 , so that the sound outlet 103 can disperse the sound emitted by the sound emitter 101 .

[0078] like Figure 5 As shown, the sound emitter 101 is arranged on the left side of the front camera module 6.

[0079] Of course, in other embodiments, the sound emitter 101 may also be arranged on the right side of the front camera module 6 .

[0080] The front camera module 6 is usually set in the middle of the top of the display module. In order to avoid the front camera module 6, the sound source 101 needs to be set on the left or right side of the front camera module 6. In order to make the sound emitted by the sound hole 103 more balanced, the sound hole 103 needs to be set in the middle of the electronic device. Figure 3 、 Figure 4 As shown, the sound emitter 101 is connected to the sound outlet 103 through the sound cavity channel 102 , and the sound cavity channel 102 needs to avoid the front camera module 6 .

[0081] In the above embodiment, the sound cavity channel avoids the front camera module 6. In other embodiments, it can also avoid other modules. The setting method of the sound cavity channel can refer to the embodiments of this application, which all fall within the protection scope of this application.

[0082] The embodiment of the present application does not limit the specific structure of the sound cavity channel. Figure 6 for Figure 3 、 Figure 4 、 Figure 5 Schematic diagram of the yoz cross section of the sound cavity channel at O ​​in the middle (the yoz cross section is perpendicular to the XY plane).

[0083] like Figure 6 As shown, a bracket 104 is provided on a side of the middle frame 3 away from the display module 2 , and the sound output device 101 is mounted on the bracket 104 .

[0084] Among them, an avoidance groove is provided at the position opposite to the sounder 101 of the middle frame 3, a first groove section 1041 is provided on the bracket 104, and a first through hole 3001 is provided on the middle frame 3. The first groove section 1041 and the first through hole 3001 are opposite to the first sound hole group 1031.

[0085] The first sound cavity 1021 includes a first groove section 1041 , a first through hole 3001 and an avoidance groove. The first sound cavity 1021 is opposite to the sound emitter 101 .

[0086] The sound emitter 101 is connected to the first sound hole group 1031 through the first slot section 1041 and the first through hole 3001 .

[0087] The sound emitter 101 , the bracket 104 , and the middle frame 3 together form a first sound cavity 1021 .

[0088] The middle frame 3 includes, for example, a carrier plate 301 and a frame 302 surrounding the carrier plate 301. In some embodiments, the frame 302 may be a frame integrally formed on the carrier plate 301, such as Figure 6 As shown, the inner wall of the frame 302 is provided with a circle of steps 3021 , and the steps 3021 are used to support the cover plate 5 . The cover plate 5 is, for example, arranged above the display module 2 and connected to the steps 3021 .

[0089] The cover plate 5 , the step 3021 and the carrying plate 301 are arranged to form a cavity, and the display module 2 is located in the cavity.

[0090] like Figure 6 As shown, the first sound cavity 1021 is connected to the first sound hole group 1031. Figure 6 The frame 302 is provided with a first sound hole group 1031 . Optionally, the first sound hole group 1031 can be provided on the cover plate 5 .

[0091] In order to ensure that the sound derived from the sound generator 101 does not leak out, Figure 5 As shown, a first sealant layer 105 is provided between the bracket 104 and the middle frame 3 , and a second sealant layer 106 is provided between the sound emitter 101 and the bracket 104 .

[0092] Optionally, the third sealant layer 107 is provided between the step 3021 and the cover plate 5. It should be noted that, in other embodiments, the third sealant layer 107 may be partially removed, or not provided, and the step 3021 only needs to be in contact with the cover plate 5.

[0093] This configuration does not limit the specific materials of the first sealant layer 105 , the second sealant layer 106 , and the third sealant layer 107 , as long as the first sealant layer 105 , the second sealant layer 106 , and the third sealant layer 107 have an adhesive effect.

[0094] Specifically, the first sealant layer 105 between the bracket 104 and the middle frame 3 is matched with the shape of the avoidance groove of the bracket 104 and the middle frame, so that the middle frame 3 is adhered to the first side of the sealant layer 105, and the bracket 104 is adhered to the second side of the sealant layer 105, thereby bonding and fixing the bracket 104 to the middle frame 3.

[0095] At the same time, the shape of the second sealant layer 106 between the sound emitter 101 and the bracket 104 is matched with the shape of the bracket 104 and the sound emitter 101, so that the sound emitter 101 is bonded to the first side of the sealant layer 105, and the bracket 104 is bonded to the second side of the sealant layer 105, thereby bonding and fixing the sound emitter 101 to the bracket 104, so that the sound emitted by the sound emitter 101 is guided to the sound outlet 103 via the first sound cavity 1021 in turn.

[0096] Furthermore, the shape of the third sealant layer 107 between the step 3021 and the cover plate 5 is respectively matched with the shape of the step 3021, so that the frame 302 is adhered to the first side of the sealant layer 105, and the cover plate 5 is adhered to the second side of the sealant layer 105, thereby bonding and fixing the cover plate 5 to the frame 302.

[0097] Because this arrangement includes the first sealing layer 105, the second sealing layer 106, and the third sealing layer 107, it effectively avoids the situation where the sound emitted by the speaker 101 leaks into the interior of the terminal device due to a loose connection between the bracket 104 and the middle frame 3, the speaker 101 and the bracket 104, or the frame 302 and the cover 5. The sound transmitted from the speaker 101 is sealed by the sealing layer 105.

[0098] Figure 7 for Figure 3 、 Figure 4 、 Figure 5 Schematic diagram of the yoz cross section of the sound cavity channel at N in the figure. Figure 7 As shown, the bracket 104 is bonded to the middle frame 3 through a first sealant layer 105 , wherein the middle frame 3 and the bracket 104 together enclose a second sound cavity 1022 .

[0099] like Figure 7 As shown, a second sound hole group 1032 is provided on the middle frame 3 , and the second sound cavity 1022 is connected to the second sound hole group 1032 . Optionally, the second sound hole group 1032 can also be provided on the cover plate 5 .

[0100] The middle frame 3 is provided with a second through hole 3002, and the bracket 104 is provided with a second slot section 1042. The second through hole 3002 and the second slot section 1042 are opposite to the second sound hole group 1032, and the second through hole 3002 and the second slot section 1042 form a second sound cavity 1022.

[0101] Figure 8 for Figure 3 、 Figure 4 、 Figure 5 Schematic diagram of the yoz cross section of the sound cavity channel at M in the figure. Figure 8 As shown, a groove 601 is provided on the middle frame 3 , the bracket 104 and the display module 2 , and the front camera module 6 is arranged in the groove 601 .

[0102] The bracket 104 is bonded to the middle frame 3 through the adhesive layer 105. The middle frame 3 is provided with a through hole 3003, and the bracket 104 is provided with a third groove section 1043. The through hole 3003 and the third groove section 1043 together form a third sound cavity 1023. The third sound cavity 1023 needs to avoid the front camera module 6 and is located on one side of the front camera module 6 ( Figure 8 The third sound cavity 1023 is located on the left side of the front camera module 6, and is located on the top of the terminal device in the actual product).

[0103] like Figure 8 As shown, a third sound hole group 1033 is provided on the middle frame 3, and the third sound cavity 1023 is connected to the third sound hole group 1033. Optionally, the third sound hole group 1033 is provided on the cover plate.

[0104] In the above embodiment, the first slot section 1041 , the second slot section 1042 , and the third slot section 1043 form a first communicating groove on the bracket 104 .

[0105] The first slot section 1041 , the first through hole 3001 and the first sound hole group 1031 are opposite to each other. The sound emitter 101 is connected to the first sound hole group 1031 via the first slot section 1041 and the first through hole 3001 .

[0106] The second slot section 1042 and the second through hole 3002 are opposite to the second sound hole group 1032 . The sound emitter 101 is connected to the second sound hole group 1032 via the first slot section 1041 , the second slot section 1042 , the third slot section 1043 and the second through hole 3002 .

[0107] The third slot section 1043 is located between the first slot section 1041 and the second slot section 1042. The third slot section 1043, the through hole 3003, and the third sound output hole group 1033 are opposite each other. The sound emitter 101 is connected to the third sound output hole group 1033 via the first slot section 1041, the second slot section 1042, and the through hole 3003. The first through hole 1031, the second through hole 1032, and the third through hole 1033 form a connected through hole on the middle frame 3. The third through hole 1033 is located between the first through hole 1031 and the second through hole 1032.

[0108] The following combination Figures 6 to 8 The flow direction of the sound inside the sound emitting device is described as follows:

[0109] First, the sound emitted by the sound emitter 101 enters the first sound cavity 1021 .

[0110] Subsequently, the first sound cavity 1021 transmits the sound entering the first sound cavity 1021 to the third sound cavity 1023 and the first sound hole group 1031 that are connected to the first sound cavity 1021 .

[0111] Subsequently, the third sound cavity 1023 transmits the sound conducted into the interior of the third sound cavity 1023 to the second sound cavity 1022 and the third sound hole group 1033 connected to the third sound cavity 1023 .

[0112] Finally, the second sound cavity 1022 guides the sound conducted into the interior of the second sound cavity 1022 to the second sound hole group 1032 .

[0113] It can be seen that, through the sound emitting device shown in this configuration, the sound emitted by the sound emitter 101 can be directed to the sound emitting hole 103 , so that the user can hear the sound emitted from the sound emitting hole 103 through the sound emitting hole 103 .

[0114] In the electronic device provided by the embodiment of the present application, the speaker is connected to the second sound hole group via the first groove and the second through hole, so that the speaker can effectively transmit the sound through the first groove and the second through hole to the second sound hole group farther away from the speaker, so that the sounds emitted by the sound hole groups at different positions are more balanced, avoiding poor sound caused by blocking one side of the sound hole when the user answers the phone, thereby improving the user experience.

[0115] like Figure 9 Shown Figure 8 In the partial enlarged view, the middle frame 3 is bonded to the bracket 104 through the sealant layer 105, and the third through hole 3003 on the middle frame 3 is connected to the third groove section 1043 on the bracket 104, together forming the third sound cavity 1023.

[0116] The width of the sound cavity channel on the middle frame, located at the junction of the middle frame 3 and the bracket, is L2. The width of the sound cavity channel on the bracket 104 is L1. The width of the sealant layer 105 on the left side of the bracket 104 is M1, and the width of the sealant layer 105 on the right side is M2.

[0117] The inclined channel of the middle frame 3 is CNC machined, subject to size and angle restrictions. If the middle frame 3 and bracket 104 remain connected to form the sound channel, the lateral dimensions of the middle frame 3 are composed of the lateral projection dimension L2 corresponding to the CNC machined dimensions and the adhesive width M1 and M2 of the earpiece bracket on the left and right sides of the sound channel. The sound channel width L1 on bracket 104 is smaller than the sound channel width L2 on the middle frame 3, and the edges of bracket 104 and middle frame 3 are flush.

[0118] An embodiment of the present application provides another terminal device.

[0119] Figure 12 A method provided in the embodiment of this application Figure 3 、 Figure 4 The yoz cross-section of the sound cavity channel at M in the middle. The specific description of the first sound cavity 1021 and the second sound cavity 1022 shown in this arrangement is detailed in the description of the first structure of the sound output device shown above, and no further details are given here.

[0120] With the above Figure 8 The difference of the first structure of the sound cavity channel shown is that Figure 12 As shown, in some embodiments of the present application, the through hole 3003 set on the middle frame 3 is changed into a second groove 3004, and the third groove section 1043 on the bracket 104 is not connected to the second groove 3004 at the position corresponding to the front camera module (such as the yoz section at point M, the third sound hole group 1033).

[0121] The opening directions of the second groove 3004 and the first groove are both toward the z direction.

[0122] In some embodiments, the third groove section 1043 and the sealant layer 105 enclose a channel 1024, wherein the channel 1024 is used to connect the first sound cavity 1021 and the second sound cavity 1022. In other embodiments, a through hole substantially along the X direction inside the bracket can serve as the channel 1024, that is, the bracket itself does not need to enclose the middle frame 3, and the channel 1024 is formed.

[0123] The first sound cavity 1021 , the channel 1024 and the second sound cavity 1022 are connected to form a sound cavity channel, and the sound cavity channel can be connected to the sound emitter 101 and the third sound hole group 1033 .

[0124] In addition, in some embodiments, the first through hole 3001 and the second through hole 3002 are connected through a second groove 3004 , and the second groove 3004 is provided on the middle frame 3 .

[0125] The second groove 3004 is arranged opposite to the front camera module 6 in the y direction. In some embodiments, the second groove 3004 is connected to the third sound hole group 1033. The third sound hole group 1033 and the second groove 3004 correspond in position in the y direction.

[0126] It should be noted that in the Y direction corresponding to the third sound hole group 1033, the channel 1024 is not connected to the third sound hole group 1033. When the second groove 3004 is provided, the second groove 3004 is connected to the third sound hole group 1033, and the channel 1024 is not connected to the second groove 3004.

[0127] like Figure 13 As shown, in this embodiment, the shared sound cavity formed by the middle frame 3 and the bracket 104 is eliminated, and only a channel 1024 (through hole) is formed on the bracket 104, and a sealant layer 105 is used to seal the plane between the bracket 104 and the middle frame 3. The lateral dimension is composed of the sealing adhesive width M1 on the left side of the channel 1024 + the through hole width L1 formed by injection molding of the earpiece bracket + the sealing width M2 on the right side of the channel 1024.

[0128] Among them, in this embodiment, the channel 1024 does not need to be connected to the second groove 3004 in the Y direction (it can be understood that the channel 1024 can be connected through the first sound cavity 1021, the second sound cavity 1022 and the second groove 3004, and is not connected in the Y direction at the position corresponding to the channel 1024 and the second groove 3004, as shown in the yoz cross-sectional view at M), so there is no need to reserve the size of L2. Therefore, the lateral size is Figure 9 The M1+L2+M2 structure becomes M1+L1+M2, resulting in a smaller lateral size. This further overcomes the size constraints of the front camera module relative to the edge of the device, allowing the front camera module to be closer to the upper edge of the display module's display area, improving the full-screen user experience and ensuring a better seal between the bracket and the middle frame.

[0129] like Figure 10 As shown, when the distance between the front camera module 6 and the display area boundary A decreases, as shown in FIG. Figure 11As shown, the size of a portion of the sound cavity channel 102 (i.e., the third sound cavity 1023) between the front camera module 6 and the sound outlet 103 is compressed, creating a bottleneck in the transmission of the sound emitted by the sound emitter 101. The sound emitted by the sound emitter 101 is difficult to transmit from the third sound cavity 1023 to the other side of the camera module (the second sound cavity 1022), resulting in low sound volume or unequal volume when holding the left and right hands during a user's call. By providing a channel 1024, this embodiment can transmit sound to the second sound outlet group 1032 through the sound guide channel, thereby improving the effect of the sound emitted from the sound outlet.

[0130] Therefore, the channel 1024 (formed by the third groove section 1043 or the channel of the bracket itself) between the front camera module 6 and the sound hole 103 is designed, and the two ends of the channel 1024 are respectively connected to the first sound cavity 1021 and the second sound cavity 1022. Compared with the aforementioned third sound cavity 1023 connected to the sound hole between the front camera module 6 and the sound hole 103, there is no need to set a through hole 3003 connected to the bracket 104 on the middle frame 3 at this position, which solves the problem of affecting the connection stability when the size of the front camera module to the edge of the whole machine is reduced, so that the front camera module can be closer to the upper boundary of the display area of ​​the display module, thereby improving the user experience of the full screen.

[0131] In the electronic device provided by the embodiment of the present application, the channel 1024 can bypass the bottleneck position between the camera module and the sound outlet, thereby directing the sound emitted by the speaker from the speaker position on one side of the camera module to the sound outlet group on the other side of the camera module, thereby improving the effect of the sound emitted from the sound outlet. In addition, the sound-emitting device does not need to set a sound cavity at the bottleneck position between the camera module and the sound outlet, saving space between the camera module and the sound outlet, allowing the camera module to be as close to the boundary of the display area as possible, effectively increasing the screen-to-body ratio of the terminal device.

[0132] In some embodiments, the second groove 3004 may not be provided on the middle frame 3 , that is, the first through hole 3001 and the second through hole 3002 are not connected through the second groove 3004 .

[0133] The following combination Figure 18 The following describes the sound flow direction of this configuration of the sound output device:

[0134] First, the sound emitted by the sound emitter 101 enters the first sound cavity 1021 .

[0135] Subsequently, the first sound cavity 1021 transmits the sound entering the first sound cavity 1021 to the channel 1024 and the first sound hole group 1031 connected to the first sound cavity 1021. In other words, the sound emitted by the sound emitter 101 can be transmitted to the first sound hole group 1031 through the first sound cavity 1021.

[0136] The channel 1024 transmits the sound entering the channel 1024 to the second sound cavity 1022 connected to the channel 1024, and the second sound cavity 1022 transmits the sound entering the second sound cavity 1022 to the second sound hole group 1032. The first sound cavity 1021, the channel 1024, and the second sound cavity 1022 are connected.

[0137] In other embodiments of the present application, a second groove 3004 is provided on the middle frame 3 , and the second groove 104 is connected to the third sound hole group 1033 .

[0138] The first sound cavity 1021 transmits the sound entering the first sound cavity 1021 to the second groove 3004 connected to the first sound cavity 1021 , and the second groove 3004 transmits the sound entering the second groove 3004 to the third sound hole group 1033 .

[0139] It can be seen that the sound emitted by the sound generator 101 in this embodiment can be transmitted to the first sound hole group 1031 through the first sound cavity 1021, and can also be transmitted to the second sound hole group 1032 through the channel 1024. Optionally, the sound can also be transmitted to the third sound hole group 1033 through the second groove 3004.

[0140] In the terminal device provided in the embodiment of the present application, the sound emitting device can conduct the sound emitted by the sound emitter through at least two flow directions, so that both sounds can be directed to the sound outlet for dissipation. It can be seen that adopting this arrangement can effectively improve the efficiency and effect of transmitting the sound emitted by the sound emitter to the sound outlet. Moreover, through the setting of the sound guide channel, the connection area between the sound cavity and the sound outlet can be effectively increased, thereby effectively improving the effect of the sound emitted from the sound outlet.

[0141] The following is shown in conjunction with the accompanying drawings Figure 18 The specific structure of the sound cavity shown is described. It should be clear that the description of the sound cavity structure in this setting is an optional example and is not limited. As long as the sound emitted by the sound emitter can be directed to the sound outlet 103 through the sound cavity:

[0142] First, please combine Figures 14 to 17 As shown, Figure 14 This is a front view of the sound device. Figure 15 This is a front view of the disassembled structure of the sound device. Figure 16 This is a schematic diagram of the back of the disassembled structure inside the sound device. Figure 14 、 Figure 15 The figure shows a top view of the structure after the display module 2 is removed from the sound output device. Figure 16 It is a schematic diagram of the disassembled structure after the housing 4 is removed from the electronic device. Figure 17 for Figure 15 Schematic diagram of the structure after a sealant layer is provided on the sound-emitting device.

[0143] In this configuration, a first sound cavity 1021 is formed between the sound emitter 101 , the bracket 104 and the middle frame 3 .

[0144] Combine Figure 14 and Figure 15 As shown in the figure, the first sound cavity 1021 is arranged above the sound emitter 101 in the Y direction and above the Z direction, and the first sound cavity 1021 and the sound emitter 101 are arranged opposite to each other. The first sound hole group 1031 is connected to the first sound cavity 1021 (see Figure 6 ).

[0145] The first sound cavity 1021 shown in this configuration can guide the sound emitted by the sound emitter 101 , thereby guiding the sound emitted by the sound emitter 101 to the sound hole group 1031 .

[0146] The bracket 104 and the middle frame 3 form a second sound cavity 1022. The second sound cavity 1022 is symmetrically arranged on the other side of the front camera (the side away from the sound source). The second sound hole group 1032 is connected to the second sound cavity 1022 (see Figure 7 ).

[0147] Combine Figure 14 and Figure 15 As shown, the first sound cavity 1021 and the second sound cavity 1022 shown in this configuration are connected to each other through the channel 1024 .

[0148] The bracket has a groove that is divided into three parts: a first groove section 1041, a second groove section 1042, and a third groove section 1043. The first groove section 1041 and the middle frame form a first sound cavity 1021, the second groove section 1042 and the middle frame form a second sound cavity 1022, and the third groove section 1043 and the middle frame form a channel 1024.

[0149] The first sound cavity 1021 is connected to the second sound cavity 1022 through the channel 1024. The channel 1024 and the front camera module 6 are opposite to each other.

[0150] The channel 1024 is arranged between the camera module and the sound outlet. The first sound cavity 1021 shown in this arrangement guides the sound emitted by the sound emitter 101 to the second sound cavity 1022 through the channel 1024.

[0151] In some embodiments, as Figure 14-17 As shown, the channel 1024 can be formed by connecting the groove provided on the bracket 104 with the surface of the middle frame 3 through the sealant layer 105. Thus, the channel 1024 is provided in the bracket, and there is no need to open an oblique hole on the middle frame ( Figure 9 As shown, a portion of the through hole 3003 is connected to the sound outlet hole group, and the channel sealing effect is better.

[0152] In other embodiments, the channel 1024 may also be a through hole dug on the bracket, and the first sound cavity 1021 and the second sound cavity 1022 are connected through the through hole. The through hole itself forms the channel 1024 and does not need to be enclosed together with the middle frame 3 to form the channel 1024.

[0153] As a result, the sound emitted by the speaker is guided from the speaker position on one side of the camera module through the channel 1024 to the sound outlet on the other side of the camera module, thereby improving the effect of the sound emitted from the sound outlet. In addition, the sound outlet device can be provided with a smaller groove 3004 or eliminate the need to provide a through hole 3003 at the bottleneck position of the middle frame between the camera module and the sound outlet. This saves space between the camera module and the sound outlet, allowing the camera module to be as close to the edge of the display area as possible, effectively increasing the screen-to-body ratio of the terminal device.

[0154] like Figure 18 As shown, in some embodiments, the first through hole 3001 and the second through hole 3002 are connected through a groove, which is provided on the middle frame 3 , namely, the second groove 3004 .

[0155] The terminal device is provided with a first sound hole group 1031, a second sound hole group 1032 and a third sound hole group 1033. The third sound hole group 1033 is located between the first sound hole group 1031 and the second sound hole group 1032. The second groove 3004 is connected to the third sound hole group 1033.

[0156] It should be noted that the channel 1024 is not connected to the third sound hole group 1033. When the second groove 3004 is provided, the second groove 3004 is connected to the third sound hole group 1033, and the channel 1024 is not connected to the second groove 3004.

[0157] The first sound cavity 1021 is connected to the second sound cavity 1022 through the channel 1024 , so that the sound emitted by the sound generator can be effectively guided to the second sound cavity 1022 through the channel 1024 and then emitted from the second sound hole group 1032 .

[0158] The first sound cavity 1021 is also connected to the third sound hole group 1033 through the second groove 3004 , so that the sound emitted by the sound generator can be guided into the second groove 3004 through the first sound cavity 1021 and then dispersed through the third sound hole group 1033 .

[0159] The sound-emitting device provided in the embodiment of the present application, by providing a channel 1024, can bypass the bottleneck between the camera module and the sound outlet, thereby directing the sound emitted by the sound emitter from the sound emitter position on one side of the camera module to the second sound cavity 1022 on the other side of the camera module, thereby improving the sound quality. The multiple channels within the sound-emitting device can conduct the sound emitted by the sound emitter to the sound outlet located at the terminal device within the limited space within the sound-emitting device, thereby effectively improving the sound guidance effect of the sound emitter and ensuring the quality of the sound emitted from the sound outlet.

[0160] In addition, the sound-emitting device does not need to set a through hole 3003 at the bottleneck position of the middle frame between the camera module and the sound hole, which saves space between the camera module and the sound hole, allowing the camera module to be as close to the boundary of the display area as possible, effectively improving the screen-to-body ratio of the terminal device.

[0161] It should be noted that the sound-emitting device can also be set at other locations of the terminal device, not only to avoid the front camera module, but also to avoid the motor, rear camera, etc., which will not be repeated here, as these all fall within the scope of protection of this application.

[0162] The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited to this. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
