[0031] The specific implementation of the present application will be described in detail below with reference to the accompanying drawings.

[0032] The embodiment of the present application is used to provide an electronic device, which can drive a display screen to make sound through piezoelectric ceramics. In the process of the display screen making sound, it not only has a good sound effect, but also can protect the privacy of the user.

[0033] In the present application, the electronic device may be a mobile phone, a laptop computer, a tablet, a large-screen device, a wearable device (e.g., a watch, smart glasses, a helmet), an augmented reality (AR) / virtual reality (VR) device, a personal digital assistant (PDA), etc., and the present application does not limit this. In the following, a mobile phone is used as an example of the electronic device 100.

[0034] Figure 1A and Figure 1B An exemplary structural diagram of an electronic device 100 provided in an embodiment of the present application is shown. Figure 1A is a front view of the electronic device 100, Figure 1B is a cross-sectional view of the electronic device 100. In the various figures herein, the X direction is the length direction of the electronic device 100, the Y direction is the width direction of the electronic device 100, and the Z direction is the thickness direction of the electronic device 100. The X direction, the Y direction, and the Z direction are perpendicular to each other.

[0035] Exemplarily, when the electronic device 100 is in the portrait state, the X direction is substantially parallel to the vertical direction; when the electronic device 100 is in the landscape state, the X direction is substantially parallel to the horizontal direction.

[0036] refer to Figure 1A and Figure 1B , the electronic device 100 includes a display screen 10 and a housing 20, and the display screen 10 is arranged on the housing 20. In this embodiment, the housing 20 includes a middle frame 21 and a back cover 22 (or "battery cover"). Along the Z direction, the display screen 10 and the back cover 22 are respectively located on opposite sides of the middle frame 21. In other embodiments, the housing 20 can be an integrated structure (that is, the middle frame 21 and the back cover 22 are integrated into one). In addition, an inner cavity 20a is formed inside the housing 20, and various functional components (not shown) of the electronic device 100 can be arranged in the inner cavity 20a, for example, a camera module, a speaker module, a communication module, a mainboard, a battery, etc.

[0037] The electronic device 100 can realize its display function through the display screen 10, for example, displaying a boot screen, an unlocking interface, an application interface, etc. In some embodiments, the display screen 10 of the electronic device 100 also has a touch function, that is, the user can input data, instructions, etc. by touching the display screen 10.

[0038] The display screen 10 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, etc., which is not limited in this embodiment.

[0039] The electronic device 100 can also realize the sound function through the display screen 10. Specifically, the electronic device 100 also includes a piezoelectric ceramic component 30, which is arranged on the inner surface of the display screen 10 (the surface of the display screen 10 facing the inner cavity 20a). Figure 1A The dotted line in the figure shows the position of the piezoelectric ceramic component 30 on the display screen 10. The piezoelectric ceramic component 30 is a device that can convert an electrical signal into a vibration signal. For example, when different voltage signals are applied to the piezoelectric ceramic component 30, the piezoelectric ceramic component 30 can generate vibrations of different amplitudes and / or frequencies. When the piezoelectric ceramic vibrates, the display screen 10 can be driven to vibrate, thereby making the display screen 10 emit sound.

[0040] Figure 2 FIG. 1 shows an exemplary application scenario in which the display screen 10 emits sound. Figure 2 When the user holds the electronic device 100 to make a call, the user can put the display screen 10 of the electronic device 100 close to the ear. At this time, the sound waves emitted by the display screen 10 can be transmitted to the human ear, so that the user can clearly hear the call sound. In order to ensure the call effect, during the call, it is hoped that the sound waves emitted by the display screen 10 can be kept within a certain area (for example, within the area Q1 covered by the human ear). If the sound wave exceeds this area, sound leakage may occur, that is, other people around the user may also hear the call sound; if the sound wave is smaller than this area, the sound wave propagation range is too small, and the user may not be able to hear the sound emitted by the display screen 10, affecting the call effect.

[0041] In addition, to meet the user's habits (for example, when the user is talking on the phone, he / she is used to holding the lower middle part of the electronic device 100 with his / her hand and aligning the upper middle part of the electronic device 100 with his / her ear), the piezoelectric ceramic component 30 can be arranged in the upper middle part of the electronic device 100, and the piezoelectric ceramic component 30 is located in the center of the electronic device 100 along the Y direction. In addition, in this document, the directional terms such as "upper", "lower", "left", and "right" are based on the vertical screen state of the electronic device 100. For example, the "upper middle part" refers to the upper middle part of the electronic device 100 in the vertical screen state.

[0042] It should be noted that Figure 2The application scenario of the display screen 10 making sounds is illustrated by taking a handheld call as an example. The present application is not limited thereto. In other embodiments, the display screen 10 making sounds can also be applied to other scenarios such as voice playback, recording playback, and music playback. In addition, in addition to making sounds through the display screen 10, the electronic device 100 can also make sounds through other devices such as speakers.

[0043] Continue to refer Figure 1A The electronic device 100 further includes a front-facing camera component 40 (as an example of an electronic component). The front-facing camera component 40 may include one or more cameras ( Figure 1A Two are shown). The user can realize the self-portrait function through the front camera component 40. For example, when the user faces the display screen 10, the user can capture his own image through the front camera component 40 and observe the shooting effect in real time on the display screen 10. To optimize the shooting effect, the front camera component 40 is set at the center of the electronic device 100 along the Y direction.

[0044] Figure 3A and Figure 3B The figure shows the installation method of the display screen 10 and the front camera assembly 40 in some electronic devices 100'. Figure 3A is an exploded view of the electronic device 100'. Figure 3B It is a front view of the display screen 10.

[0045] refer to Figure 3A The electronic device 100' comprises a display screen 10, a middle frame 21 and a back cover 22 arranged in sequence along the Z direction. The middle frame 21 comprises a frame 211 and a panel 212. One side of the panel 212 ( Figure 3A The left side shown in FIG. 1 is opposite to the display screen 10, and the other side of the panel 212 ( Figure 3A The panel 212, the frame 211 and the back cover 22 together form an inner cavity 20a of the electronic device 100'.

[0046] The display screen 10 is bonded to the panel 212 of the middle frame 21 by means of adhesive 51, and the front camera assembly 40 is installed in the inner cavity 20a of the electronic device 100'. The middle frame 21 is provided with a plurality of through holes 23, so that external light can enter the front camera assembly 40 through the through holes 23. Figure 3B A space R is formed between the area where the through hole 23 is set on the panel 212 and the display screen 10.

[0047] In order to prevent dust, water vapor, etc. from entering the front camera assembly 40 through the through hole 23, the electronic device 100' further includes a back glue 52 (the back glue section 511 is a common section of the back glue 51 and the back glue 52) surrounding the space R in the circumferential direction, and the back glue 52 is used to bond the display screen 10 and the panel 212. In this way, the back glue 52 can form a sealing strip that seals the space R in the circumferential direction to prevent dust, water vapor, etc. from entering the front camera assembly 40 through the through hole 23.

[0048] Figure 3B A front view of the display screen 10 is shown (for ease of understanding, Figure 3B The positions of adhesives 51 and 52 are shown by thick dotted lines in FIG. Figure 3B After the display screen 10 and the panel 212 are bonded by the adhesive 52, the position where the adhesive 52 is set on the display screen 10 will be fixed. In this way, when the piezoelectric ceramic component 30 drives the display screen 10 to vibrate and make a sound, the vibration will be stopped at the position where the adhesive 52 is transmitted (that is, the vibration area of ​​the display screen 10 is Q2). In this way, the vibration area of ​​the display screen 10 is too small (for example, smaller than the area Q1 covered by the human ear), which affects the sound effect of the display screen 10, and the user may not hear the sound emitted by the display screen 10.

[0049] refer to Figure 4 In some embodiments, the front camera assembly 40 can be offset to solve this problem (for ease of observation, Figure 4 1 shows a front view of the electronic device 100" with the display screen 10 removed). In this embodiment, the front camera assembly 40 is arranged at the top corner of the electronic device 100" (for example, the upper left corner), rather than being arranged at the top center of the electronic device 100". In this way, there can be a large distance between the back glue 52 and the piezoelectric ceramic assembly 30, and the display screen 10 can have a sufficient vibration area, thereby ensuring the sound effect of the display screen 10.

[0050] However, the scheme of offsetting the front camera component 40 may affect the user experience. For example, when the user is taking a selfie facing the display screen 10, the front camera component 40 is not facing the user, but is offset to one side of the user (for example, the left side). Therefore, the picture captured by the front camera component 40 is not the picture of the user in the center, but the picture of the user offset to one side. At this time, the selfie picture seen by the user on the display screen 10 will be inconsistent with the picture intuitively imagined, thereby affecting the user experience.

[0051] To this end, the present embodiment provides an electronic device, which can achieve a good display screen sound effect under any setting of the shooting component bias (for example, setting the front shooting component at the top center of the electronic device). In this embodiment, different sealing materials are used to seal the space R. That is, on the side of the space R away from the piezoelectric ceramic component, a first sealing material is used for sealing, and the first sealing member can provide a fixed connection between the display screen and the middle frame (therefore, the first sealing member can also be called a "rigid sealing member"); on the side of the space R close to the piezoelectric ceramic component, a second sealing member is used for sealing, and the second sealing member can provide an elastic connection between the display screen and the middle frame (therefore, the second sealing member can also be called an "elastic sealing member"). In some embodiments, the rigid seal can be a back glue, and the flexible seal can be a foam or liquid silicone.

[0052] In this way, when the vibration of the display screen is transmitted to the location of the flexible seal, the middle frame will not prevent the vibration of the display screen, and the vibration of the display screen can continue to propagate forward, so that the display screen has a sufficient vibration area to ensure the sound effect of the display screen. In addition, when the vibration of the display screen is transmitted to the location of the rigid seal, the vibration of the display screen is stopped because the display screen is fixed to the middle frame at this location, so that the vibration area of ​​the display screen can be limited to a certain range to ensure user privacy.

[0053] FIG. 5A to FIG. 5C FIG. 1 is a schematic diagram showing the structure of the electronic device 100 provided in this embodiment. Figure 5A is an exploded view of the electronic device 100, Figure 5B This is a front view of the electronic device 100 after the display screen 10 is removed. Figure 5C is a cross-sectional view of the electronic device 100 ( Figure 5B AA cross-section diagram).

[0054] refer to FIG. 5A to FIG. 5C , the electronic device 100 includes a display screen 10, a middle frame 21, and a back cover 22 connected in sequence along the Z direction (as the second direction). As described above, the middle frame 21 and the back cover 22 together form the housing 20 of the electronic device 100. In other embodiments, the middle frame 21 and the back cover 22 may also be an integrated structure.

[0055] The display screen 10 extends along the XY plane (as the first plane). In some examples, the display screen 10 may be a flat screen, and the plane on which the display screen 10 is located may be parallel to the XY plane. In other examples, the display screen 10 may also be a curved screen, and the curved screen may be convex or concave with a small arc relative to the XY plane.

[0056] The middle frame 21 includes a frame 211 and a panel 212. The frame 211 extends along the circumference of the electronic device 100 and can form a side frame of the electronic device 100. Therefore, the frame 211 can also be understood as the side wall of the electronic device 100. The panel 212 is arranged on the frame 211, and the panel 212 and the display screen 10 are arranged opposite to each other along the Z direction. The display screen 10 can be bonded to the panel 212 by the back glue 51. In addition, the side of the display screen 10 can also be bonded to the middle frame 21 by a caulking glue (not shown) to seal the space between the display screen 10 and the middle frame 21. The back cover 22 is connected to the frame 211, and the back cover 22 and the middle frame 21 together enclose the inner cavity 20a of the electronic device 100.

[0057] The display screen 10 includes a first area 11 and a second area 12 which are arranged opposite to each other along the X direction (as an example of the first direction). Figure 5A The first area 11 and the second area 12 are framed with dotted lines. Along the Z direction, the first area 11 is opposite to the front camera assembly 40 (as an example of an electronic assembly), and the second area 12 is used to mount the piezoelectric ceramic assembly 30. Exemplarily, the size of the second area 12 is the same as the size of the mounting surface of the piezoelectric ceramic assembly 30.

[0058] The piezoelectric ceramic component 30 can drive the display screen 10 to vibrate and generate sound. For example, the piezoelectric ceramic component 30 can be bonded to the inner surface of the display screen 10 (the surface of the display screen 10 facing the inner cavity 20a). In addition, a mounting hole 24 can be provided on the panel 212 of the middle frame 21, and the piezoelectric ceramic component 30 can extend through the mounting hole 24 to the inner cavity 20a of the electronic device 100.

[0059] In the present application, A and B are arranged relative to each other in a certain direction, which means that A and B are arranged face to face in the direction, and the projections of A and B in the direction at least partially overlap. On this basis, A and B can be arranged at intervals in the direction, or they can be in contact with each other.

[0060] The panel 212 of the middle frame 21 includes a first panel 212a, and the first panel 212a is arranged opposite to the first area 11 of the display screen 10. In some embodiments, the first panel 212a can be understood as a partial area of ​​the panel 212. When the display screen 10 is mounted on the panel 212, there is a space R between the first panel 212a and the first area 11 of the display screen 10. One or more through holes 23 (two through holes 23 are shown in the figure) are opened on the first panel 212a, and each through hole 23 is connected to the space R. The shape of the through hole 23 is not limited in this embodiment, and the through hole 23 can be any shape such as circular, square, irregular, etc., as long as it penetrates the first panel 212a along the Z direction.

[0061] The front camera assembly 40 (as an example of an electronic assembly) is installed on the side of the through hole 23 facing away from the display screen 10, that is, the through hole 23 can spatially connect the space R and the front camera assembly 40. It can be understood that the front camera assembly 40 can achieve light exchange with the outside of the electronic device 100 through the through hole 23. In this embodiment, the front camera assembly 40 is arranged at the top middle position of the electronic device 100. In other embodiments, the front camera assembly 40 can also be arranged at other positions, for example, the upper left corner or the upper right corner of the electronic device 100.

[0062] In this embodiment, the front-facing camera component 40 is taken as an example of an electronic component. In other embodiments, the electronic component may be other components, such as a depth-sensing camera (also known as a "TOF camera"), a flash, a breathing light, and other components that need to interact with the outside of the electronic device 100 via light, or a motor, a speaker, and other components that do not need to exchange light with the outside of the electronic device 100.

[0063] In addition, in this embodiment, the electronic component and the piezoelectric ceramic component 30 are arranged relative to each other along the X direction (corresponding to the first area 11 and the second area 12 of the display screen 10 being arranged relative to each other along the X direction), that is, in this embodiment, the X direction is used as an example of the first direction. In other embodiments, the first direction may also be other directions parallel to the XY plane, for example, the Y direction. That is, in this embodiment, the electronic component and the piezoelectric ceramic component 30 are arranged relative to each other along the Y direction (corresponding to the first area 11 and the second area 12 of the display screen 10 being arranged relative to each other along the Y direction).

[0064] Continue to refer Figure 5A and Figure 5C Since the first panel 212a is provided with a through hole 23, the front camera assembly 40 and the space R can be spatially connected through the through hole 23. In this way, dust, water vapor, etc. in the inner cavity 20a of the electronic device 100 may enter the front camera assembly 40, affecting the normal use of the front camera assembly 40.

[0065] To this end, the electronic device 100 further includes a sealing component 60, which is disposed between the display screen 10 and the first panel 212a, and is disposed around the first area 11 along the circumference of the first area 11 (the circumference direction of the first area 11), and is used to seal the space R along the circumference of the first area 11. In this way, the sealing component 60 can block the dust and water vapor in the inner cavity 20a from spreading to the front camera component 40, and protect the front camera component 40.

[0066] Specifically, refer to Figure 5A, the first region 11 includes four sides, namely, side 111, side 112, side 113 and side 114). Among them, side 111 (as the first side) and side 112 (as the second side) are arranged oppositely along the X direction, and side 113 (as the third side) and side 114 (as the fourth side) are arranged oppositely along the Y direction (as the third direction). It can be understood that along the X direction, side 111 is the side of the first region 11 away from the second region 12, and side 112 is the side of the first region 11 close to the second region 12.

[0067] This embodiment does not limit the extension shape of each side of the first region 11. Each side can be a straight line (for example, the side 111 is a straight line), or a curve or a broken line. Adjacent side edges can be perpendicular to each other (for example, the side 111 and the side 113 are perpendicular to each other), or they can be non-perpendicular.

[0068] The sealing assembly 60 extends along the side edges 111, 112, 113, and 114 to circumferentially surround the first area 11. The segments of the sealing assembly 601 extending along the side edges 111, 112, 113, and 114 are respectively the sealing segments 60a, 60b, 60c, and 60d. It can be understood that the extension shape of each sealing segment is consistent with the extension shape of the corresponding side edge.

[0069] In order to make the display screen 10 have a good sound effect, in this embodiment, the sealing assembly 60 includes a rigid sealing member 61 (i.e., a first sealing member) and an elastic sealing member 62 (i.e., a second sealing member) sequentially arranged along the circumference of the first area 11. For easy observation, Figure 5A and Figure 5B The rigid seal 61 and the elastic seal 62 are shown by different hatching lines. Figure 5A and Figure 5B The rigid seal 61 is at least provided on the side 111, and the elastic seal 62 is at least provided on the side 112. That is, the rigid seal 61 includes at least a sealing section 60a, and the elastic seal 62 includes at least a sealing section 60b.

[0070] Among them, the rigid seal 61 is used to provide a fixed connection between the display screen 10 and the first panel 212a, and the elastic seal 62 is used to provide an elastic connection between the display screen 10 and the first panel 212a. That is to say, the area of ​​the display screen 10 where the rigid seal 61 is set will basically not be displaced or can only be very slightly displaced relative to the first panel 212a (this displacement is recorded as δ1), while the position of the display screen 10 where the elastic seal 62 is set can produce a larger displacement relative to the first panel 212a (this displacement is recorded as δ2). Among them, the displacement δ2 is much larger than the displacement δ1, for example, the displacement δ2 is more than 5 times the displacement δ1. Exemplarily, the rigid seal 61 can be a backing adhesive, for example, acrylic pressure-sensitive adhesive, butyl rubber, silicone adhesive, etc. The elastic seal can be foam or liquid silicone.

[0071] It can be understood that, since the sealing section 60b is used to provide an elastic connection between the display screen 10 and the first panel 212a, the vibration of the display screen 10 can continue to be transmitted forward after being transmitted to the side edge 112, so as to expand the sound-emitting area of ​​the display screen 10, thereby achieving a better sound-emitting effect. In addition, since the sealing section 60a is used to provide a fixed connection between the display screen 10 and the first panel 212a, the vibration of the display screen 10 will stop being transmitted forward after being transmitted to the side edge 111, so as to limit the vibration range of the display screen 10 to a certain area, thereby avoiding sound leakage and protecting user privacy.

[0072] The distance D1 between the side 111 and the second area 12 can be determined according to the sound effect of the display screen 10, for example, by means of testing or simulation. In some embodiments, the distance D1 between the side 111 and the second area 12 can be half of the sound wave area Q1 covered by the human ear when the human ear is close to the display screen 10, for example, 2 cm to 4 cm.

[0073] In some embodiments, along the X direction, the side 113 is aligned with the middle area of ​​the second area 12. That is, along the X direction, the projection of the side 113 in the second area 12 is located in the middle area of ​​the second area 12. The middle area of ​​the second area 12 is located at the center of the second area 12 along the Y direction, and the ratio of the size of the middle area along the Y direction to the size of the second area 12 along the Y direction is a predetermined value, for example, a value between 0.2 and 0.6.

[0074] In this embodiment, since the side 113 is aligned with the middle of the second area 12, the end of the sealing section 60c (the sealing section arranged on the side 113) close to the second area 12 is provided with an elastic sealing material. That is, the elastic sealing member 62 is also provided at the end of the side 113 close to the second area 12. In this way, after the vibration of the display screen 10 is transmitted to the lower end point of the side 113 (the end point of the side 113 close to the second area 12), it can continue to propagate upwards, so as to expand the vibration area of ​​the display screen 10.

[0075] refer to Figure 5B Since the elastic seal 62 and the rigid seal 61 are made of different materials, there may be a certain gap between the elastic seal 62 and the rigid seal 61 after they are arranged on the first panel 212a. To this end, the sealing assembly 60 may further include a third seal 63, which is used to fill the gap between the elastic seal 62 and the rigid seal 61 to ensure the circumferential sealing of the space R.

[0076] In some embodiments, the third sealing member 63 is an elastic colloid (for example, dam glue), so that when the display screen 10 and the panel 212 of the middle frame 21 are attached, the third sealing member 63 can be compressed, thereby improving the sealing effect of the sealing assembly 60. Exemplarily, the thickness (dimension along the Z direction) of the third sealing member 63 in a free state is greater than the thickness of the first sealing member, so as to further improve the sealing effect.

[0077] Continue to refer FIG. 5A to FIG. 5C , the panel 212 of the middle frame 21 includes a second panel 212b. In some embodiments, the second panel 212b can be understood as another part of the panel 212 (different from the area of ​​the first panel 212a). The second panel 212b is arranged opposite to the display screen 10 along the Z direction, and is arranged opposite to the first panel 212a along the X direction. In some embodiments, the second panel 212b is located below the first panel 212a.

[0078] In order to further improve the privacy protection effect of the electronic device 100, the electronic device 100 further includes a connector 70. Along the X direction, the connector 70 is located on the side of the second area 12 of the display screen 10 that is away from the first area 11, and is used to fix the display screen 10 and the second panel 212b. That is, at the position where the connector 70 is located, the display screen 10 and the second panel 212b are fixedly connected. In this way, when the vibration of the display screen 10 is transmitted to the position of the connector 70, it will stop transmitting forward, so as to limit the vibration range of the display screen 10 to a certain area, thereby avoiding sound leakage and protecting user privacy.

[0079] Along the X direction, the distance D2 between the connecting member 70 and the second area 12 can be determined according to the sound effect of the display screen 10, for example, by means of testing or simulation. In some embodiments, the distance D2 between the connecting member 70 and the second area 12 can be half of the sound wave area Q1 covered by the human ear when the human ear is close to the display screen 10, for example, 2 cm to 4 cm.

[0080] In some embodiments, the connecting member 70 is a colloid (e.g., hot melt adhesive). For example, the connecting member 70 may be a strip of colloid extending along the Y direction (as the third direction), or the connecting member 70 may be a plurality of dot-shaped colloids (e.g., Figure 5A and Figure 5B shown).

[0081] refer to Figure 5C The surface of the second panel 212b facing the connector 70 (e.g., hot melt adhesive) may be made of heat-insulating material 212b-1 (e.g., plastic material). Thus, the heat generated by the hot melt adhesive can be prevented from diffusing to the outside of the electronic device 100, thereby preventing the user from feeling a burning sensation when holding the electronic device 100. The surface of the second panel 212b facing away from the connector 70 (e.g., hot melt adhesive) may be made of metal material 212b-2.

[0082] Exemplarily, the size of the connector 70 along the Y direction may be determined according to the sound effect of the display screen 10. In some embodiments, the size of the connector 70 along the Y direction may be substantially the same as the size of the second area 12 along the Y direction, or may be slightly smaller than the size of the second area 12 along the Y direction, for example, 0.5 to 0.8 times the size of the second area 12 along the Y direction.

[0083] Figure 6 FIG. 1 is a schematic diagram showing the sound emission area of ​​the display screen 10 provided in an embodiment of the present application. Figure 6 The display screen 10 includes a fixed area, a moderately fixed area and an amplitude area. The fixed area can be the bonding area between the piezoelectric ceramic component 30 and the display screen 10 (the piezoelectric ceramic component 30 can be bonded to the display screen 10 by adhesive), and the fixed area can be understood as the vibration center of the display screen 10 when the sound is emitted.

[0084] The proper fixing area is the area where the display screen 10 is fixedly connected to the panel 212 of the middle frame 21. For example, the proper fixing area on the upper side is the area where the sealing section 60a of the sealing assembly 60 is set, the proper fixing area on the upper side is the area where the connecting member 70 is set, and the proper fixing areas on the left and right sides are the areas where the left and right sides of the adhesive 51 are set, respectively. When the vibration of the display screen 10 is transmitted to the proper fixing area, it will stop transmitting forward to limit the vibration range of the display screen 10 to a certain area, thereby avoiding sound leakage and protecting user privacy.

[0085] The area between the fixed area and the moderately fixed area is the amplitude area. In the amplitude area, the display screen 10 is basically not constrained by the panel 212 of the middle frame 21 and can generate relatively large amplitude vibrations, thereby ensuring the sound effect of the display screen 10.

[0086] The following describes an exemplary assembly process of the electronic device 100 provided in an embodiment of the present application. Figure 7When assembling the electronic device 100, first, place the middle frame assembly (including the middle frame 21 and the rigid seal 61, elastic seal 62 and back glue 51 preset on the panel 212 of the middle frame 21) in the glue dispensing fixture, and apply the caulking glue (not shown) and the dam glue 63. Then, install the display screen 10 on the middle frame 21 and fix it under pressure. After that, place the assembled display screen 10 and the middle frame 21 in the automated assembly equipment, and use CCD positioning to pass the piezoelectric ceramic assembly 30 through the mounting hole 24 on the panel 212 of the middle frame 21, fit it to the display screen 10 and keep it under pressure; then, assemble the FPC and gold fingers of the piezoelectric ceramic assembly 30 to the corresponding positions of the inner cavity 20a of the shell 20. Finally, assemble the front camera assembly 30, the main board, the battery, etc. to the corresponding positions of the inner cavity 20a of the shell 20, cover the back cover 22, and the assembly of the electronic device 100 can be completed.

[0087] In the above description of this embodiment, unless otherwise specified, “ / ” means or, for example, A / B can identify A or B; “and / or” in this article is merely a way to describe the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can represent the existence of A alone, B alone, and A and B at the same time.
