[0125] Please refer to Figure 1A, which is a schematic diagram of the structure of the electronic device 100 provided in this application in some embodiments.

[0126] In some embodiments, the electronic device 100 can be a foldable terminal device, a candybar terminal device, a tablet computer, a multimedia player, headphones, a speaker, a laptop computer, an in-vehicle device, a television, or a wearable device, etc., that has audio playback capabilities. The electronic device 100 in the embodiment shown in Figure 1A is illustrated using a mobile phone as an example. Of course, other types of electronic devices 100 can also adopt similar structures, which will not be elaborated upon further below.

[0127] Exemplarily, the electronic device 100 can include a first screen 1, a middle frame 2, and a back cover assembly 3. The first screen 1 and the back cover assembly 3 can be mounted on opposite sides of the middle frame 2. The first screen 1, the middle frame 2, and the back cover assembly 3 can collectively enclose an interior of the electronic device 100. The first screen 1 can be a flexible display screen or a rigid display screen. The first screen 1 can be an organic light-emitting diode (OLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a quantum dot light emitting diodes (QLED) display screen, a liquid crystal display (LCD), or the like.

[0128] Exemplarily, the electronic device 100 can further include a lens module (not shown in the figure), which can be mounted in the interior of the electronic device 100. The lens module can be used to implement a photographing function. The lens module can be, but is not limited to, a periscope lens or a straight lens, or the like.

[0129] Please refer to FIG. 1A and FIG. 1B, FIG. 1B is a structural schematic diagram of the electronic device 100 along the line A-A in some embodiments.

[0130] In some embodiments, the electronic device 100 can further include a loudspeaker 4. The loudspeaker 4 can be mounted between the first screen 1 and the back cover assembly 3. The electronic device 100 can have a sound outlet 5, and the loudspeaker 4 can play sound to the outside of the electronic device 100 through the sound outlet 5.

[0131] Exemplarily, the process of the loudspeaker 4 playing audio can be: the electronic device 100 decodes an audio file into a digital signal, performs digital-to-analog conversion on the digital signal to restore it to an analog signal, then amplifies the analog signal and inputs it to the loudspeaker 4, and the loudspeaker 4 plays the audio. After the voice coil of the loudspeaker 4 receives a current signal, the energized voice coil is subjected to a magnetic force in the magnetic field environment of the magnetic circuit assembly of the loudspeaker 4, thereby causing the diaphragm to vibrate and achieving sound production.

[0132] The electronic device 100 and the loudspeaker 4 can together form a front cavity 6, so that the loudspeaker 4 can transmit sound to the sound outlet 5 through the front cavity 6.

[0133] In other embodiments, the electronic device 100 can further include a plurality of loudspeakers 4, which can be used to emit sound of a plurality of audio tracks to form stereo sound.

[0134] It should be noted that FIG. 1A and FIG. 1B only schematically show some components of the electronic device 100, and actual shapes and actual sizes of the components are not limited by FIG. 1A, FIG. 1B and the following drawings.

[0135] The surrounding structure of the front cavity 6 and the position setting of the sound outlet 5 will be introduced below in combination with the relevant drawings.

[0136] Please continue to refer to FIG. 1A and FIG. 1B, in some embodiments, the sound outlet 5 can be arranged on the back cover assembly 3, or the sound outlet 5 can be surrounded by the back cover assembly 3 and the middle frame 2.

[0137] In the embodiment, the sound outlet 5 is arranged on the back side of the electronic device 100, so that the loudspeaker 4 can sound towards the back side or the oblique back side or the side of the electronic device 100 through the sound outlet 5, thereby increasing the sound direction of the electronic device 100, which is conducive to optimizing the sound way of the electronic device 100 and enriching the application scenarios of the electronic device 100. For example, it is conducive to improving the sound collection effect of the user through the back side of the electronic device 100, and the electronic device 100 can still normally sound when the front side of the electronic device 100 is blocked. It should be noted that the back side of the electronic device 100 refers to the side of the electronic device 100 facing away from the first screen 1.

[0138] For example, the middle frame 2 can have a top side 201 and a bottom side 202 arranged in the length direction. Along the thickness direction of the electronic device 100, the orthographic projection of the sound outlet 5 on the middle frame 2 can fall between the top side 201 and the bottom side 202.

[0139] In the embodiment, the sound outlet 5 is arranged between the top side 201 and the bottom side 202, so that the arrangement position of the sound outlet 5 is different from the conventional arrangement direction, thereby increasing the sound direction of the electronic device 100, which is conducive to the electronic device 100 adapting to more sound environments.

[0140] For example, the loudspeaker 4 can have a sound emitting surface 401, which can be arranged towards the back cover assembly 3. The loudspeaker 4 and the back cover assembly 3 can be surrounded to form a front cavity 6, and the sound emitting surface 401 is exposed to the front cavity 6.

[0141] In the embodiment, the sound emitting surface 401 of the loudspeaker 4 is arranged towards the back cover assembly 3, so that the diaphragm of the loudspeaker 4 can face the back cover assembly 3, thereby enabling the loudspeaker 4 to play audio towards the direction of the back cover assembly 3, and playing sound to the outside of the electronic device 100 through the front cavity 6 and the sound outlet 5 in turn, which is conducive to shortening the length of the sound transmission path between the loudspeaker 4 and the sound outlet 5, and further improving the sound emitting effect of the loudspeaker 4.

[0142] The orientation of the sound outlet 5 can form an angle between 0° and 180° with the sound outlet surface 401, as long as the sound outlet 5 can realize sound emission at the back side of the electronic device 100.

[0143] The back cover assembly 3 can include a battery cover 301, a lens decoration (not shown in the figure) and a lens glass (not shown in the figure). The battery cover 301 can be installed on the side of the middle frame 2 away from the first screen 1. The lens decoration can be installed on the side of the battery cover 301 away from the first screen 1 and correspond to the lens module. The lens glass can be installed on the side of the lens decoration 302 away from the first screen 1 and correspond to the lens module. It should be noted that the back cover assembly 3 can also only include the battery cover 301.

[0144] The battery cover 301 can be provided with a sound outlet 5, or the edges of the lens decoration and the battery cover 301 can surround to form a sound outlet 5, or the edges of the lens glass and the edges of the lens decoration can surround to form a sound outlet 5, or the lens glass can be provided with a sound outlet 5, or the edges of the battery cover 301 and the edges of the middle frame 2 can surround to form a sound outlet 5, etc.

[0145] It should be noted that the sound outlet 5 can be arranged at any position on the back side of the electronic device 100, as long as the loudspeaker 4 can realize sound emission at the back side of the electronic device 100 through the sound outlet 5. The sound emission to the side edge at the back side of the electronic device 100 can also be understood as sound emission at the back side of the electronic device 100.

[0146] Next, the sound outlet 5 arranged on the battery cover 301 will be described in detail.

[0147] Please refer to FIG. 1A to FIG. 2, FIG. 2 is a perspective exploded view of the electronic device 100 shown in FIG. 1A in some embodiments.

[0148] In some embodiments, the electronic device 100 can further include a bracket 7, a first mounting pad 8, a first sealing ring 9, a first sound emission sealing ring 10, a sound emission mesh 11 and a second mounting pad 12.

[0149] For example, the bracket 7 can be located between the loudspeaker 4 and the back cover assembly 3, the bracket 7 can be installed on the bracket 7, and the bracket 7 can surround the loudspeaker 4 to form the front cavity 6. The bracket 7 can have a first through hole 701, one end of the first through hole 701 can communicate with the front cavity 6, and the other end of the first through hole 701 can communicate with the sound outlet 5.

[0150] In the embodiment, the front cavity 6 is formed by the bracket 7 and the loudspeaker 4, so that the enclosure of the front cavity 6 can be decoupled from other structural members, and the enclosure of the front cavity 6 does not need the battery cover 301, thereby reducing the consistency difference caused by the mounting tolerance fluctuation or deformation fluctuation of the battery cover 301, avoiding the influence of the battery cover 301 on the volume change of the front cavity 6, improving the stability of the front cavity 6, and facilitating the improvement of the sound output effect.

[0151] Specifically, in the assembly process of the electronic device 100, the structure of the electronic device 100 on the side of the middle frame 2 away from the first screen 1 is relatively complex, so that the assembly chain of the electronic device 100 on the side of the middle frame 2 away from the first screen 1 is relatively long, for example, the lens module, the battery, the circuit board assembly and other structures need to be installed on the side of the middle frame 2 away from the first screen 1. In addition, the battery cover 301 is usually the last installation process to seal the side of the middle frame 2 away from the first screen 1, so that in the assembly process of the electronic device 100, the installation tolerance fluctuation of the battery cover 301 is large. If the front cavity 6 is directly formed by the battery cover 301 and the loudspeaker 4, the size of the front cavity 6 is easy to change, and the size change has randomness, which is difficult to capture the law for prediction, so that the actual size of the front cavity 6 deviates from the theoretical design size. The design of the front cavity 6 is important for the sound output effect of the loudspeaker 4, so that the sound output effect of the loudspeaker 4 is unstable.

[0152] In addition, after the assembly of the electronic device 100 is completed, if the front cavity 6 is directly formed by the battery cover 301 and the loudspeaker 4, the battery cover 301 is easy to deform due to the external force in the use process of the electronic device 100, thereby generating size fluctuation, and thus affecting the size of the front cavity 6, so that the sound output effect of the loudspeaker 4 is reduced.

[0153] Therefore, in the embodiment, the front cavity 6 is formed by the bracket 7 and the loudspeaker 4, and the battery cover 301 is not involved in the enclosure of the front cavity 6, so as to avoid the influence of the assembly tolerance or size fluctuation of the battery cover 301, facilitate the improvement of the size consistency of the front cavity 6, ensure the stability of the sound output, and thus improve the sound output effect.

[0154] For example, the bracket 7 can be arranged around the periphery of the loudspeaker 4, so as to form a part of the bracket 7 arranged around the loudspeaker 4, and facilitate the sealing of the front cavity 6 formed by the bracket 7 and the loudspeaker 4.

[0155] For example, the first mounting pad 8 can be mounted between the side of the loudspeaker 4 away from the bracket 7 and the middle frame 2.

[0156] In the embodiment, the first mounting pad 8 is arranged, so that the stability of the bracket 7 mounting the loudspeaker 4 to the middle frame 2 is improved, so that the stability of the front cavity 6 is improved, and the sound effect is improved.

[0157] The first mounting pad 8 can be in a compressed state, so that the fit between the bracket 7 and the loudspeaker 4 is improved, so that the mounting stability of the bracket 7 and the loudspeaker 4 is improved, so that the stability of the front cavity 6 is improved, and the sound effect is improved.

[0158] The material of the first mounting pad 8 can be, but is not limited to, back adhesive, or foam, or foam adhesive, etc., or the first mounting pad 8 can be formed by a dispensing process.

[0159] For example, the first sealing ring 9 can be arranged between the loudspeaker 4 and the bracket 7, and the first sealing ring 9 can be arranged around the periphery of the sound emitting surface 401.

[0160] In the embodiment, the first sealing ring 9 is arranged, so that the sealing effect between the bracket 7 and the loudspeaker 4 is improved, so that the sealing effect of the front cavity 6 is improved, and the sound effect of the loudspeaker 4 is improved.

[0161] The first sealing ring 9 can be in a compressed state, so that the fit between the bracket 7 and the loudspeaker 4 is further improved, so that the mounting stability of the bracket 7 and the loudspeaker 4 is improved, so that the sealing effect of the front cavity 6 is further improved, and the sound effect is improved.

[0162] The material of the first sealing ring 9 can be, but is not limited to, back adhesive, or foam, or foam adhesive, etc., or the first sealing ring 9 can be formed by a dispensing process.

[0163] For example, the sound emitting mesh 11 can be mounted on the sound emitting port 5, for dust prevention at the sound emitting port 5, to prevent external impurities from entering the sound cavity and affecting the sound effect.

[0164] The second mounting pad 12 can be used to mount the sound emitting mesh 11 to the battery cover 301, so as to maintain the stable mounting of the sound emitting mesh 11.

[0165] The second mounting pad 12 can be, but is not limited to, back adhesive, or foam adhesive, or formed by a dispensing process.

[0166] Please refer to FIG. 1B, FIG. 3A and FIG. 3B, FIG. 3A is a structural schematic diagram of the middle frame 2 in the electronic device 100 shown in FIG. 1A in some embodiments; and FIG. 3B is a structural schematic diagram of the middle frame 2 shown in FIG. 3A after being cut along the line B-B in some embodiments.

[0167] In some embodiments, the middle frame 2 can have a mounting groove 203, and the opening of the mounting groove 203 can be arranged towards the battery cover 301.

[0168] Exemplarily, the groove bottom of the mounting groove 203 can be provided with a limiting structure 2031.

[0169] In some examples, the limiting structure 2031 can be a limiting block, which can be protruded from the groove bottom of the mounting groove 203. The number of the limiting blocks can be multiple, wherein part of the limiting blocks can be arranged along the first side wall of the mounting groove 203, and the other part of the limiting blocks can be arranged along the second side wall of the mounting groove 203, and the first side wall and the second side wall are two side walls adjacent to the mounting groove 203.

[0170] In the embodiment, part of the limiting blocks arranged along the first side wall among the multiple limiting blocks can form a limiting space with the side wall of the mounting groove 203, and the limiting direction is the direction intersecting with the first side wall. Part of the limiting blocks arranged along the second side wall among the multiple limiting blocks can also form a limiting space with the side wall of the mounting groove 203, and the limiting direction is the direction intersecting with the second side wall.

[0171] In other examples, the limiting structure 2031 can be a limiting groove, which can be recessed from the groove bottom of the mounting groove 203, and the limiting is formed by the inner side wall of the limiting groove.

[0172] It should be noted that the limiting structure 2031 can be provided with both the limiting block and the limiting groove, and the limiting is realized by the limiting block and the limiting groove at the same time, so as to realize multiple limiting.

[0173] In some examples, the middle frame 2 can also have a first fixing groove 204, which can be recessed from the surface of the middle frame 2 facing the battery cover 301. Wherein, the first fixing groove 204 can be located at one side of the mounting groove 203, and the first fixing groove 204 can be in communication with the mounting groove 203.

[0174] Exemplarily, the first fixing groove 204 can include a first part 204a and a second part 204b. Wherein, the first part 204a of the first fixing groove 204 can be in communication with the mounting groove 203, and the second part 204b of the first fixing groove 204 can be arranged at one side of the first part 204a of the first fixing groove 204 and extend towards the side edge of the first part 204a of the first fixing groove 204.

[0175] Wherein, the groove bottom wall of the second part 204b of the first fixing groove 204 can be provided with a limiting column 2041, which is protruded from the groove bottom wall of the second part 204b of the first fixing groove 204.

[0176] In some embodiments, the middle frame 2 can further have a second fixing groove 205, which can be recessed on the surface of the middle frame 2 facing the battery cover 301. The second fixing groove 205 can be located on one side of the mounting groove 203, and the second fixing groove 205 can be in communication with the mounting groove 203.

[0177] In some examples, the second fixing groove 205 and the first fixing groove 204 can be located on different sides of the mounting groove 203.

[0178] In other examples, the second fixing groove 205 and the first fixing groove 204 can be located on the same side of the mounting groove 203, and the second fixing groove 205 and the first fixing groove 204 can be arranged at intervals.

[0179] In some embodiments, the middle frame 2 can further have a third fixing groove 206, which can be recessed on the sidewall of the mounting groove 203.

[0180] For example, the third fixing groove 206 and the second fixing groove 205 can be located on the same side of the mounting groove 203, and the third fixing groove 206 can be arranged at intervals with the second fixing groove 205.

[0181] The number of third fixing grooves 206 can be multiple, and the multiple third fixing grooves 206 can be arranged on both sides of the second fixing groove 205.

[0182] In other embodiments, the third fixing groove 206 can also be located on a different side of the mounting groove 203 from the second fixing groove 205.

[0183] Please refer to FIG. 4, FIG. 5A and FIG. 5B. FIG. 4 is a structural schematic diagram of the middle frame 2 shown in FIG. 3A installing the speaker 4 in some embodiments. FIG. 5A is a structural schematic diagram of the partial structure of the electronic device 100 shown in FIG. 4 along the C-C line after being cut open in some embodiments. FIG. 5B is a structural schematic diagram of the partial structure of the electronic device 100 shown in FIG. 4 along the D-D line after being cut open in some embodiments.

[0184] In some embodiments, the speaker 4 can be accommodated in the mounting groove 203 and installed on the groove bottom wall of the mounting groove 203. The sound emitting surface 401 of the speaker 4 is arranged away from the groove bottom wall of the mounting groove 203.

[0185] In this embodiment, by installing the speaker 4 in the mounting groove 203, the size space additionally occupied by the speaker 4 can be reduced by using the groove space of the mounting groove 203, and at least part of the thickness of the speaker 4 can be covered by the thickness of the middle frame 2, which is conducive to the lightweight design of the electronic device 100.

[0186] Exemplarily, the loudspeaker 4 can be installed and arranged corresponding to the limiting structure 2031, and the loudspeaker 4 is limited by the limiting structure 2031 to improve the stability of the loudspeaker 4 installed in the middle frame 2, thereby improving the sound output stability of the loudspeaker 4, and being conducive to improving the sound output effect.

[0187] In some examples, the limiting structure 2031 can be a limiting block, and the limiting of the loudspeaker 4 can be achieved by the limiting block cooperating with the side wall of the installation slot 203. In other examples, the limiting structure 2031 can be a limiting slot, and the limiting of the loudspeaker 4 can be achieved by the side wall of the limiting slot.

[0188] Specifically, the limiting structure 2031 is taken as a limiting block, and the first side wall of the installation slot 203 is parallel to the length direction of the electronic device 100, and the second side wall of the installation slot 203 is parallel to the width direction of the electronic device 100. As shown in FIG. 5A, the limiting block arranged in parallel to the second side wall cooperates with the side wall of the installation slot 203 to form the limiting installation of the loudspeaker 4, and the limiting direction intersects the second side wall. As shown in FIG. 5B, the limiting block arranged in parallel to the first side wall cooperates with the slot wall of the installation slot 203 to form the limiting installation of the loudspeaker 4, and the limiting direction intersects the first side wall. Therefore, by limiting the loudspeaker 4 with the limiting block, the loudspeaker 4 can be limited in the length direction and the width direction of the electronic device 100, thereby achieving the stable installation of the loudspeaker 4.

[0189] It should be noted that FIGS. 5A and 5B illustrate the limiting structure 2031 as a limiting block, and it can be understood that FIGS. 5A and 5B do not limit the specific structure of the limiting structure 2031, as long as the limiting structure 2031 can achieve the limiting installation of the loudspeaker 4.

[0190] Exemplarily, the first installation pad 8 can have adhesion, so that the loudspeaker 4 can be adhered to the slot bottom wall of the installation slot 203 by the first installation pad 8, thereby further improving the stability of the loudspeaker 4 installed in the middle frame 2, and further improving the sound output stability of the loudspeaker 4.

[0191] In some examples, the loudspeaker 4 can include a first part 4a and a second part 4b, the first part 4a of the loudspeaker 4 can be installed on the slot bottom wall of the installation slot 203, and the second part 4b of the loudspeaker 4 is connected to the side of the first part 4a of the loudspeaker 4 away from the slot bottom wall of the installation slot 203. Wherein, the surface of the second part 4b of the loudspeaker 4 away from the slot bottom wall is the sound output surface 401 of the loudspeaker 4.

[0192] Exemplarily, the circumferential dimension of the second part 4b of the speaker 4 can be smaller than that of the first part 4a of the speaker 4, so that the side surface of the first part 4a of the speaker 4 connecting the second part 4b of the speaker 4 is larger than the second part 4b of the speaker 4, thereby forming a mounting surface 402 surrounding at least part of the peripheral edge of the sound output surface 401, and the mounting surface 402 is located on the side surface of the first part 4a of the speaker 4 connecting the second part 4b of the speaker 4.

[0193] Among them, the mounting surface 402 can be arranged around the peripheral edge of the sound output surface 401 to form a "hui" - shaped structure, or the mounting surface 402 can be arranged around part of the peripheral edge of the sound output surface 401 to form a "U" - shaped structure, or a "C" - shaped structure, or a "two" - shaped structure, etc.

[0222] Please refer to FIGS. 8, 9A and 9B, FIG. 8 is a schematic structural view of the support 7 shown in FIG. 7A installed in the electronic device 100 shown in FIG. 4 in some embodiments; FIG. 9A is a schematic structural view of the electronic device 100 shown in FIG. 8 along the line F-F in some embodiments; and FIG. 9B is a schematic structural view of the electronic device 100 shown in FIG. 8 along the line G-G in some embodiments.

[0223] In some embodiments, the first part 7a of the support 7 can be at least partially located in the mounting groove 203, and the first part 7a of the support 7 can be arranged around the periphery of the loudspeaker 4 to form the front cavity 6 together with the loudspeaker 4. The first through hole 701 can communicate with the front cavity 6.

[0224] In the present embodiment, the first part 7a of the support 7 is arranged around the periphery of the loudspeaker 4, which can improve the sealing performance of the support 7 and the loudspeaker 4 forming the front cavity 6, thereby improving the sound output effect of the loudspeaker 4. The front cavity 6 can be communicated with the first through hole 701 and the first recess 703 in sequence through the first through hole 701.

[0225] For example, the first portion 7a of the support 7 can be arranged around the periphery of the sound emitting surface 401, so that the sound emitting surface 401 can be completely exposed to the front cavity 6, reducing the risk of the sound emitting surface 401 being blocked, and facilitating better sound emission of the loudspeaker 4.

[0226] The first sealing ring 9 can be arranged on the mounting surface 402 of the loudspeaker 4 and located between the mounting surface 402 and the first portion 7a of the support 7.

[0227] In this embodiment, the first sealing ring 9 can improve the sealing performance between the first portion 7a of the support 7 and the mounting surface 402, thereby improving the sealing performance of the sound cavity and facilitating the sound emission effect of the loudspeaker 4. In addition, since the first sealing ring 9 can be in a compressed state, the sealing effect between the first portion 7a of the support 7 and the mounting surface 402 can be further improved. In addition, since the first sealing ring 9 can be glue, the first portion 7a of the support 7 and the mounting surface 402 can be bonded, thereby improving the connection stability of the mounting surface 402 and the first portion 7a of the support 7, and further improving the sealing effect between the first portion 7a of the support 7 and the mounting surface 402.

[0228] In this embodiment, since the support 7 can be fixed to the middle frame 2, and the support 7 and the loudspeaker 4 are connected by the first sealing ring 9, the loudspeaker 4 and the bottom wall of the mounting groove 203 can be connected by the first mounting pad 8, and the first sealing ring 9 and the first mounting pad 8 can be in a compressed state, i.e., the first sealing ring 9 and the first mounting pad 8 can have a deformation ability. Therefore, the stability of the loudspeaker 4 fixed to the bottom wall of the mounting groove 203 by the support 7 can be improved by the deformation ability of the first sealing ring 9 and the first mounting pad 8, and the size tolerance of the support 7 or the mounting groove 203 can also be compensated, avoiding the loosening of the loudspeaker 4.

[0229] In some embodiments, the second portion 7b of the support 7 can extend outwardly toward the mounting groove 203 and be fixedly connected to the middle frame 2.

[0230] In this embodiment, the first portion 7a of the support 7 can be fixed to the middle frame 2 by the second portion 7b of the support 7, so that the front cavity 6 is only surrounded by the support 7 and the loudspeaker 4, thereby decoupling from other structures of the electronic device 100, reducing the risk of interference of other structures of the electronic device 100 on the front cavity 6, and facilitating the sound emission effect of the electronic device 100.

[0231] Exemplarily, the second portion 7b of the bracket 7 can be mounted to the first fixing groove 204. Specifically, the second portion 7b of the bracket 7 can be mounted to the first portion 204a of the first fixing groove 204, so that the inner wall of the first portion 204a of the first fixing groove 204 can form a limit to the second portion 7b of the bracket 7, thereby improving the stability of the bracket 7 mounted to the middle frame 2.

[0232] In some embodiments, the third portion 7c of the bracket 7 can extend outwardly towards the mounting groove 203 and be fixed to the middle frame 2.

[0233] In the present embodiment, the first portion 7a of the bracket 7 can be fixed to the middle frame 2 by the third portion 7c of the bracket 7, so that the surrounding of the front cavity 6 only needs the bracket 7 and the loudspeaker 4, thereby decoupling from other structures of the electronic device 100, reducing the risk of interference of other structures of the electronic device 100 on the front cavity 6, and being conducive to improving the sound output effect of the electronic device 100.

[0234] In the present embodiment, the third portion 7c of the bracket 7 and the second portion 7b of the bracket 7 can be connected to different sides of the first portion 7a of the bracket 7, so that the third portion 7c of the bracket 7 and the second portion 7b of the bracket 7 can jointly fix the first portion 7a of the bracket 7 from different directions, thereby improving the stability of the bracket 7 mounted to the middle frame 2.

[0235] Exemplarily, the third portion 7c of the bracket 7 can be mounted to the second fixing groove 205, so that the inner wall of the second fixing groove 205 can form a limit to the third portion 7c of the bracket 7, thereby improving the stability of the bracket 7 mounted to the middle frame 2.

[0236] In some embodiments, the fourth portion 7d of the bracket 7 can be located outside the mounting groove 203 and be fixed to the middle frame 2.

[0237] In the present embodiment, the second portion 7b of the bracket 7 can be fixedly connected to the middle frame 2 with the assistance of the fourth portion 7d of the bracket 7, thereby further improving the stability of the bracket 7 mounted to the middle frame 2.

[0238] Exemplarily, the fourth portion 7d of the bracket 7 can be mounted to the second portion 204b of the first fixing groove 204, so that the inner wall of the second portion 204b of the first fixing groove 204 can form a limit to the fourth portion 7d of the bracket 7, thereby improving the stability of the bracket 7 mounted to the middle frame 2.

[0239] The first limiting hole 704 of the fourth part 7d of the support 7 can be sleeved on the limiting column 2041 located at the second part 204b of the first fixing groove 204, so that the limiting column 2041 forms a limit to the first limiting hole 704, which improves the limiting effect of the middle frame 2 on the fourth part 7d of the support 7, and further improves the stability of the support 7 installed on the middle frame 2.

[0240] In some embodiments, the fifth part 7e of the support 7 can be fixedly connected to the middle frame 2 by a fastener (not shown in the figure).

[0241] In the embodiment, the fifth part 7e of the support 7 is installed on the middle frame 2 by a fastener, which can further improve the connection stability of the support 7 and the middle frame 2, and the fastener can provide a pressing force for the support 7 in the thickness direction of the electronic device 100 to stably press the support 7 on the middle frame 2, which can improve the installation stability between the support 7 and the middle frame 2, and improve the sealing performance of the support 7 and the loudspeaker 4.

[0242] In the embodiment, the fifth part 7e of the support 7, the third part 7c of the support 7 and the second part 7b of the support 7 can be connected to different sides of the first part 7a of the support 7 respectively, so that the support 7 can be fixedly connected to the support 7 in multiple directions to form a stable three-edge connection structure, which improves the stability of the support 7 installed on the middle frame 2.

[0243] For example, the fastener can be installed through the second limiting hole 705 of the fifth part 7e of the support 7.

[0244] The fifth part 7e of the support 7 can be located in the installation groove 203 to make full use of the internal space of the installation groove 203, reduce the additional space occupied by the fastener, and improve the utilization rate of the internal space of the electronic device 100.

[0245] Please refer to FIG. 10A and FIG. 10B, FIG. 10A is a structural schematic diagram of a part of the electronic device 100 shown in FIG. 8 along the line H-H in some embodiments; and FIG. 10B is a structural schematic diagram of a part of the electronic device 100 shown in FIG. 8 along the line I-I in some embodiments.

[0246] In some embodiments, the sixth part 7f of the support 7 can be installed on the third fixing groove 206 located at the side wall of the installation groove 203.

[0247] In the embodiment, the sixth part 7f of the support 7 is clamped on the middle frame 2 by cooperating with the third fixing groove 206, which realizes the limiting of the middle frame 2 on the support 7 in the thickness direction of the electronic device 100, and improves the stability of the support 7 installed on the middle frame 2.

[0248] In the embodiment, the sixth portion 7f of the support 7 can be connected to the same side of the first portion 7a of the support 7 as the third portion 7c of the support 7, so that the sixth portion 7f of the support 7 can strengthen the stability of the third portion 7c of the support 7 mounted to the middle frame 2.

[0249] In the embodiment, the sixth portion 7f of the support 7 can be connected to the same side of the first portion 7a of the support 7 as the third portion 7c of the support 7, so that the sixth portion 7f of the support 7 can strengthen the stability of the third portion 7c of the support 7 mounted to the middle frame 2.

[0250] In some embodiments, the seventh portion 7g of the support 7 can be clamped to the side of the speaker 4 opposite to the third fixing groove 206.

[0251] In the embodiment, the seventh portion 7g of the support 7 can be clamped to the side of the speaker 4 opposite to the third fixing groove 206.

[0252] In the embodiment, the seventh portion 7g of the support 7 can be clamped to the side of the speaker 4 opposite to the third fixing groove 206.

[0253] Referring to FIG. 11, FIG. 11 is a structural schematic diagram of the sound outlet mesh 11 in the electronic device 100 shown in FIG. 1A in some embodiments.

[0254] In some embodiments, the sound outlet mesh 11 can include a first portion 11a and a second portion 11b.

[0255] For example, the first portion 11a of the sound outlet mesh 11 can be provided with a plurality of through holes 111. In the embodiment, the air permeability of the sound outlet mesh 11 can be improved by the plurality of through holes 111, so that sound can be transmitted out through the plurality of through holes 111.

[0256] It should be noted that the through holes 111 in FIG. 11 are circular holes for illustration. It can be understood that the shape of the through holes 111 can also be other shapes, such as triangular, rectangular, prismatic, irregular, or a combination of multiple shapes, etc., which are not limited herein.

[0257] For example, the second portion 11b of the sound outlet mesh 11 can be connected to the periphery of the first portion 11a of the sound outlet mesh 11 and extend towards the periphery of the first portion 11a of the sound outlet mesh 11.

[0258] For example, the second portion 11b of the sound outlet mesh 11 can be connected to the periphery of the first portion 11a of the sound outlet mesh 11 and extend towards the periphery of the first portion 11a of the sound outlet mesh 11.

[0259] Please refer to FIGS. 12A-13. FIG. 12A is a structural schematic diagram of the electronic device 100 shown in FIG. 11, in which the sound outlet mesh 11 is installed in the sound outlet 5; FIG. 12B is a structural schematic diagram of a part of the electronic device 100 shown in FIG. 12A from another perspective; and FIG. 13 is a structural schematic diagram of a part of the electronic device 100 shown in FIG. 12A along the line J-J.

[0260] In some embodiments, the first portion 11a of the sound outlet mesh 11 can be filled in the sound outlet 5, and the second portion 11b of the sound outlet mesh 11 can be fixed to the surface of the battery cover 301.

[0261] In the present embodiment, the second portion 11b of the sound outlet mesh 11 can improve the stability of the installation of the first portion 11a of the sound outlet mesh 11 in the sound outlet 5, thereby improving the stability of the sound outlet at the sound outlet 5. In addition, since the first portion 11a of the sound outlet mesh 11 has a plurality of through holes 111, the airflow uniformity at the first portion 11a of the sound outlet mesh 11 can be improved, thereby improving the sound outlet effect.

[0262] For example, the second mounting pad 12 is located between the second portion 11b of the sound outlet mesh 11 and the battery cover 301.

[0263] In the present embodiment, the second mounting pad 12 can improve the stability of the installation of the second portion 11b of the sound outlet mesh 11 in the battery cover 301, thereby improving the stability of the installation of the first portion 11a of the sound outlet mesh 11 in the sound outlet 5.

[0264] Please refer to FIGS. 1B, 12B and 14. FIG. 14 is a structural schematic diagram of the electronic device 100 shown in FIG. 1A along the line K-K.

[0265] In some embodiments, the opening of the first recess 703 of the support 7 can face the battery cover 301, and the first recess 703 can communicate the first through hole 701 and the sound outlet 5.

[0266] In some embodiments, the through hole 111 of the sound outlet mesh 11 can be communicated with the front cavity 6. Specifically, the through hole 111 can be communicated with the front cavity 6 through the first recess 703 and the first through hole 701 in sequence, so that the sound emitted by the loudspeaker 4 can pass through the front cavity 6, the first through hole 701, the first recess 703 and the through hole 111 in sequence.

[0267] In some embodiments, the second part 11b of the sound outlet mesh 11 can be connected to the periphery of the first part 11a of the sound outlet mesh 11 close to the front cavity 6, and the second part 11b of the sound outlet mesh 11 is fixed to the surface of the rear cover assembly 3 exposed to the front cavity 6. In this embodiment, the second part 11b of the sound outlet mesh 11 is arranged inside the electronic device 100, which is conducive to improving the appearance of the electronic device 100.

[0268] For example, the side of the first part 11a of the sound outlet mesh 11 which is not provided with the second part 11b of the sound outlet mesh 11 faces the first through hole 701.

[0269] In this embodiment, since the propagation direction of the sound is from the first through hole 701 to the sound outlet 5, the second part 11b of the sound outlet mesh 11 is not arranged on the side of the first part 11a of the sound outlet mesh 11 facing the first through hole 701, which can reduce the gas flow resistance and thus reduce the propagation interference of the sound, thereby improving the sound emission effect.

[0270] In some embodiments, the first sound emission sealing ring 10 can be arranged between the support 7 and the battery cover 301. Specifically, the first sound emission sealing ring 10 can be arranged around the periphery of the first through hole 701 and the first recess 703.

[0271] In this embodiment, the first sound emission sealing ring 10 can improve the sealing between the support 7 and the battery cover 301, thereby improving the sound emission effect.

[0272] For example, the first sound emission sealing ring 10 can also be arranged around the periphery of the sound outlet mesh 11 to further improve the sealing of the periphery of the sound outlet 5, thereby improving the sound emission effect.

[0273] In this embodiment, since the first sound emission sealing ring 10 can be in a compressed state, the sealing between the battery cover 301 and the middle frame 2 is further improved.

[0274] In some embodiments, the support column 702 can abut against the battery cover 301 to support the battery cover 301, thereby reducing the risk of deformation of the battery cover 301 and reducing the risk of change in the size of the space between the sound outlet 5 and the first through hole 701, thereby improving the sound emission effect.

[0275] Please continue to refer to FIG. 1B and FIG. 14, in some embodiments (please refer to FIG. 7A), the first portion 7031a of the first slot bottom wall 7031 and the third portion 7031c of the first slot bottom wall 7031 can be parallel to the sound outlet face 401, the third portion 7031c of the first slot bottom wall 7031 can be higher than the first portion 7031a of the first slot bottom wall 7031 along the thickness direction of the support 7, and the second portion 7031b of the first slot bottom wall 7031 can be inclined relative to the first portion 7031a of the first slot bottom wall 7031.

[0276] In this embodiment, through the design of the first slot bottom wall 7031, the internal space utilization rate of the electronic device 100 can be improved by avoiding other structures inside the electronic device 100, and the airflow guiding effect can be achieved, which is conducive to better guiding the sound emitted through the first through hole 701 to the sound outlet 5 and optimizing the sound outlet effect.

[0277] In some other embodiments, the first slot bottom wall 7031 can be parallel to the sound outlet face 401, which is conducive to increasing the cross-sectional area of the sound transmission path between the first through hole 701 and the sound outlet 5, so that a better resonance frequency can be obtained between the first through hole 701 and the sound outlet 5 to optimize the sound outlet effect.

[0278] In some embodiments, the sound outlet 5 can include a plurality of portions arranged at intervals, and the plurality of portions of the sound outlet 5 are in communication with the front cavity 6, so as to change the sound outlet mode of the sound outlet 5 and enrich the sound outlet mode of the electronic device 100 to cater to different application scenarios.

[0279] In some embodiments, the ratio of the area of the part of the sound outlet face 401 exposed to the front cavity 6 to the total area of the sound outlet face 401 can be greater than or equal to 3 / 4, so as to avoid that the sound outlet face 401 is blocked too much in the enclosed structure of the front cavity 6, which is conducive to the loudspeaker 4 to emit sound to the front cavity 6 through the sound outlet face 401, thereby improving the sound outlet effect.

[0280] In some embodiments, along the thickness direction of the electronic device 100, the sound outlet 5 has a projection in the plane of the sound outlet face 401, and at least part of the projection falls within a circular range with a center radius of 30 mm of the sound outlet face 401.

[0281] In this embodiment, by designing the relative position of the sound outlet 5 and the sound outlet face 401, the distance between the sound outlet 5 and the sound outlet face 401 can be prevented from being too far, so as to shorten the sound outlet path and improve the sound outlet effect.

[0282] It should be noted that the circular range with a center radius of 30 mm of the sound outlet face 401 refers to a circular range with the center of the sound outlet face 401 as the center.

[0283] Exemplarily, the sound outlet 5 can be disposed at least partially opposite to the first through hole 701, so as to further shorten the path length between the front cavity 6 and the sound outlet 5, and to facilitate optimization of the sound emission effect. It should be noted that the opposite disposition refers to that, along the thickness direction of the electronic device 100, the orthographic projection of the sound outlet 5 on the support 7 can at least partially coincide with the first through hole 701.

[0284] In some embodiments, when the loudspeaker 4 is working, the resonance frequency in the front cavity 6 can be greater than or equal to 2.5 kHz, so as to achieve a better sound emission effect. For example, the resonance frequency in the front cavity 6 can be, but is not limited to, 2.5 kHz, or 2.6 kHz, or 2.7 kHz, or 2.8 kHz, or 2.9 kHz, or other values greater than 2.5 kHz.

[0285] Exemplarily, along the thickness direction of the electronic device 100, the height range of the front cavity 6 can be in the range of 0.5 mm to 1 mm, so that the front cavity 6 can have a better resonance frequency, thereby achieving a better sound emission effect. For example, the height range of the front cavity 6 can be, but is not limited to, 0.5 mm, or 0.6 mm, or 0.7 mm, or 0.8 mm, or 0.9 mm, or 1 mm, or other values between 0.5 mm and 1 mm.

[0286] In some embodiments, when the loudspeaker 4 is working, the resonance frequency at the sound outlet 5 can be greater than or equal to 2.5 kHz, so as to achieve a better sound emission effect. For example, the resonance frequency at the sound outlet 5 can be, but is not limited to, 2.5 kHz, or 2.6 kHz, or 2.7 kHz, or 2.8 kHz, or 2.9 kHz, or other values greater than 2.5 kHz.

[0287] Exemplarily, the sound emission area of the sound outlet 5 can be greater than or equal to 9 mm 2 , so that the sound outlet 5 can have a better resonance frequency, thereby achieving a better sound emission effect. For example, the sound emission area of the sound outlet 5 can be, but is not limited to, 9 mm 2 , or 9.1 mm 2 , or 9.2 mm 2 , or 9.3 mm 2 , or 9.4 mm 2 , or 9.5 mm 2 , or other values greater than 9 mm 2 .

[0288] It should be noted that, when the sound outlet 5 is a plurality of parts arranged at intervals, the sound emission area of the sound outlet 5 is the sum of the areas of the plurality of parts. When the sound outlet 5 is provided with the sound emission mesh 11, the sound emission area of the sound outlet 5 is the sum of the areas of the through holes 111 on the sound emission mesh 11.

[0289] Next, the assembly process of the electronic device 100 in some embodiments is introduced.

[0290] In some embodiments, the assembly process of the electronic device 100 can include steps one, two, three and four.

The third mounting pad 13 is located between the fourth mounting pad 14 and the loudspeaker 4.

[0306] The third mounting pad 13 and the fourth mounting pad 14 can be in a compressed state to improve the stability of the loudspeaker 4 mounted on the first screen 1.

[0307] The material of the third mounting pad 13 can be, but is not limited to, adhesive, or foam, or foam adhesive, etc., or the third mounting pad 13 can be formed by a dispensing process.

[0308] The material of the fourth mounting pad 14 can be, but is not limited to, adhesive, or foam, or foam adhesive, etc., or the fourth mounting pad 14 can be formed by a dispensing process.

[0309] It should be noted that in some other embodiments, the electronic device 100 can not include the fourth mounting pad 14, and directly connect the loudspeaker 4 and the first screen 1 through the third mounting pad 13.

The inner diameter of the first portion 207a of the mounting hole 207 can be smaller than the inner diameter of the second portion 207b of the mounting hole 207. The communication between the first portion 207a of the mounting hole 207 and the second portion 207b of the mounting hole 207 forms a limiting wall 2071.

[0313] It should be noted that the dashed line in FIG. 17B is a schematic division of the first portion 207a and the second portion of the mounting hole 207. It can be understood that in other embodiments, the division of the first portion 207a and the second portion of the mounting hole 207 can also be located at other positions.

[0382] Specifically, the fourth sound outlet sealing ring 20 can be arranged around the periphery of the third through hole 3022 to ensure the sealing of the front cavity 6 around the periphery of the third through hole 3022.

[0383] In some embodiments, the fourth sound outlet sealing ring 20 can be in a compressed state to improve the stability of the installation of the lens glass 303 on the lens decoration 302.

[0384] In some embodiments, the material of the fourth sound outlet sealing ring 20 can be, but is not limited to, adhesive, or foam, or foam adhesive, etc., or the fourth sound outlet sealing ring 20 can be formed by a dispensing process.

[0385] In some embodiments, the lens glass 303 can be provided with a sound outlet 5, and the sound outlet 5 can be arranged at least partially opposite to the third through hole 3022.

[0386] In the present embodiment, the front cavity 6 jointly enclosed by the lens glass 303, the lens decoration 302, the battery cover 301, the middle frame 2 and the loudspeaker 4 has a relatively large size, which is conducive to the sound effect of the loudspeaker 4, and the sound outlet 5 is arranged at least partially opposite to the third through hole 3022, which is conducive to improving the sound effect of the electronic device 100.

[0387] Next, other morphological designs of the electronic device 100 will be introduced.

[0388] Please refer to FIGS. 35-37, FIG. 35 is a structural schematic diagram of the electronic device 100 in some embodiments of the present application; FIG. 36 is a structural schematic diagram of the electronic device 100 in an intermediate state; and FIG. 37 is a structural schematic diagram of the electronic device 100 in a closed state. It should be noted that the electronic device 100 shown in FIGS. 35-37 can include some features of the electronic device 100 shown in FIGS. 1A-34, and the same features will not be described here.

[0389] In some embodiments, the electronic device 100 is a foldable electronic device 100. As shown in FIG. 35, the electronic device 100 can be unfolded to an open state to expose the first screen 1. As shown in FIG. 36, the electronic device 100 can also be in an intermediate state between the open and closed states, so that the first screen 1 is partially folded towards each other. As shown in FIG. 37, the electronic device 100 can also be folded to a closed state, so that the first screen 1 is folded or covered by the back cover assembly 3.

[0390] In some embodiments, the electronic device 100 can include a first part 100a and a second part 100b, and the first part 100a of the electronic device 100 can rotate relative to the second part 100b of the electronic device 100 to realize the conversion between the open state, the intermediate state and the closed state of the electronic device 100.

[0391] It should be noted that the electronic device 100 shown in FIGS. 35-37 can include the speaker, the support, the front cavity and the sound outlet 5 of any of the foregoing embodiments.

[0392] In the prior art, the electronic device 100 includes a conventional sound outlet (not shown in the figure), which can be arranged on one side of the first screen 1 or on the top side surface 201 or the bottom side surface 202 of the middle frame 2. In this way, when the electronic device 100 is in the closed state, the conventional sound outlet arranged on one side of the first screen 1 will be covered, and at this time, the sound output effect of the electronic device 100 will be disturbed. Although the conventional sound outlet arranged on the top side surface 201 or the bottom side surface 202 of the middle frame 2 is not covered, the sound output from the top and bottom of the electronic device 100 is not good in some scenarios. For example, in the scenario where the user holds the electronic device 100 to put it next to the ear to listen to the sound, the user usually holds one side of the back cover assembly 3 of the electronic device 100 towards the ear, at this time, the sound output mode of the conventional sound outlet does not conform to the user's usage habit, which seriously affects the user experience.

[0393] In the embodiment, the sound outlet 5 is arranged on the back cover assembly 3 or surrounded by the back cover assembly 3 and the middle frame, and is exposed when the electronic device 100 is in the closed state. The exposed position of the sound outlet 5 is close to one side of the back cover assembly 3, which can optimize the sound effect of the electronic device 100 on one side of the back cover assembly 3, so that the electronic device 100 still has good sound effect in the closed state, and the use experience is improved. For example, when answering a call, the user does not need to open the electronic device 100 to the open state, but can directly answer the call in the closed state, and the same or similar sound experience as in the open state can be achieved.

[0394] For example, the electronic device 100 can further include a second screen 21, which can be arranged on the battery cover 301 and away from the first screen 1. When the electronic device 100 is in the closed state, the second screen 21 can be exposed and can be used when the electronic device 100 is in the closed state.

[0395] The sound outlet 5 can be exposed when the electronic device 100 is in the closed state, so that the sound outlet 5 can still emit sound outward when the electronic device 100 is in the closed state, and other structures are not blocked, which is beneficial to improve the sound effect of the electronic device 100 in the closed state.

[0396] The sound outlet 5 can be arranged on the first part 100a of the electronic device 100, and / or the sound outlet 5 can be arranged on the second part 100b of the electronic device.

[0397] The second screen 21 can be arranged on the first part 100a of the electronic device 100, and / or the second screen 21 can be arranged on the second part 100b of the electronic device.

[0398] It should be noted that the relative position relationship between the sound outlet 5 and the second screen 21 is not limited. When the electronic device 100 is in the closed state, the sound outlet 5 and the second screen 21 can be arranged on the same side of the electronic device 100, or the sound outlet 5 and the second screen 21 can be arranged on opposite sides of the electronic device 100.

[0399] It should be noted that the electronic device 100 can further include a lens glass 303, and the lens glass 303, the second screen 21 and the sound outlet 5 can be arranged on the battery cover 301 in any manner as long as the sound outlet 5 can be exposed when the electronic device 100 is in the closed state.

[0400] It should be noted that in some other embodiments, the electronic device 100 can further not include the second screen 21, or the electronic device 100 can further not include the lens glass 303.

[0401] It should be noted that the electronic device 100 can further include a plurality of sound outlets 5, each of which can be designed in any of the manners described above, and the sound outlets 5 can have different design manners to enrich the sound output manner of the electronic device 100 and improve the sound output effect of the electronic device 100.

[0402] It should be noted that the electronic device 100 can further include a conventional sound outlet (not shown in the figure), which can be arranged at one side of the first screen 1 or at the top side surface 201 or the bottom side surface 202 of the middle frame 2, and the conventional sound outlet and the sound outlet 5 provided in the embodiments of the present application can cooperate to output sound to enrich the sound output manner of the electronic device 100 and improve the sound output effect of the electronic device 100.

[0403] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and any combination of the features in different embodiments is also within the protection scope of the present application, that is, the above-described multiple embodiments can also be combined as needed.

[0404] It should be noted that all the above-mentioned drawings are exemplary illustrations of the present application and do not represent the actual size of the product. The size ratio relationship between the components in the drawings is not a limitation on the actual product of the present application.

[0405] The above is only some embodiments and implementation manners of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application.
