Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of mobile terminal technology, and in particular, to an electronic device. Background Art
[0002] With the development of mobile phones, the sound outlet slit of the top speaker is getting closer and closer to the top of the screen. To ensure the performance of the top speaker, existing mobile phones generally have a small sound outlet slit at the top of the phone's display. When the user holds the phone to make a call, the sound emitted by the top speaker can enter the user's ear through the small sound outlet slit. However, the width of the small sound outlet slit is generally narrow, which can easily become blocked during long-term use, affecting the sound output. Moreover, opening holes or slits in the phone's display makes it impossible to achieve a full-screen design. Summary of the Invention
[0003] The present invention provides an electronic device for solving the problem of mobile phone speaker sound output, preventing the sound holes or sound slits provided on the display from being blocked, thereby affecting the sound output of the speaker. While meeting the sound output requirements of the electronic device, a 100% full-screen design of the mobile phone display is achieved.
[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:
[0005] In a first aspect, an electronic device is provided, comprising a display screen, a middle frame, and a back cover. The display screen is connected to one side of the middle frame, and the back cover is connected to the other side of the middle frame. The display screen, the middle frame, and the back cover form an enclosed space. The electronic device also includes an audio exciter and a speaker, both of which are located within the enclosed space. The audio exciter is connected to the display screen or the back cover. After receiving an electrical signal, the audio exciter generates vibrations, which drive the display screen or the back cover to vibrate and produce sound. A sound-emitting structure is provided at one end of the middle frame, and the sound generated by the speaker is emitted through the sound-emitting structure. The display screen is a full-screen display.
[0006] On this basis, by installing a speaker and an audio exciter in the electronic device, the audio exciter can be connected to the display screen and drive the display screen to vibrate and produce sound. The speaker and display screen jointly produce sound, which can meet the requirements of the electronic device's in-ear loudness and reduce call leakage. By placing the speaker's sound output structure on the middle frame, the sound output structure can meet the speaker's sound propagation requirements while avoiding the need for holes or seams in the display screen, preventing the holes or seams in the display screen from being blocked during long-term use. At the same time, the integrity of the display screen can be maintained, allowing the display screen to be set to 100% full screen.
[0007] In one possible implementation of the first aspect, the middle frame includes a first end and a second end that are opposite to each other, and the electronic device includes a first speaker and a second speaker. The sound output structure includes a first sound output structure and a second sound output structure, with the first sound output structure being disposed at the first end and the second sound output structure being disposed at the second end. The first speaker is disposed near the first end and emits sound through the first sound output structure; the second speaker is disposed near the second end and emits sound through the second sound output structure.
[0008] On this basis, by arranging two speakers at both ends of the electronic device and providing a corresponding sound output structure for each speaker, the two sound output structures are located at both ends of the electronic device. This allows the electronic device to simultaneously emit sound from both ends when playing audio or video, thus achieving stereo sound output from the electronic device and improving the sound output effect of the electronic device.
[0009] In one possible implementation of the first aspect, the middle frame includes a frame and a support plate, the support plate being connected to the frame and having a notch disposed on the support plate. The display screen is disposed on one side of the support plate, and the first speaker is disposed on the other side of the support plate, with the first speaker covering the notch. The first speaker, the support plate, the display screen, and the frame form a sound output cavity, which communicates with the outside world via the first sound output structure.
[0010] On this basis, by providing a separate sound output cavity for the first speaker, the sound of the first speaker can be transmitted to the outside of the device through the sound output cavity and the first sound output structure, thereby preventing the sounds of the first speaker and the second speaker from crosstalking and interfering with each other inside the electronic device, thereby achieving a better sound generation effect in the electronic device.
[0011] In a possible implementation manner of the first aspect, the first speaker is connected to the support plate via a sealing gasket, which prevents sound leakage from the first speaker.
[0012] On this basis, by providing a sealing gasket, the tightness of the connection between the first speaker and the support plate is increased, thereby preventing the sound emitted by the first speaker from leaking from the sound cavity.
[0013] In a possible implementation of the first aspect, the first sound outlet structure includes one or more first sound outlet holes, and the second sound outlet structure includes one or more second sound outlet holes. This implementation illustrates a specific design of the first sound outlet structure and the second sound outlet structure.
[0014] In one possible implementation of the first aspect, the first sound outlet is shaped like a circle, an ellipse, a racetrack, or a regular polygon, and the second sound outlet is shaped like a circle, an ellipse, a racetrack, or a regular polygon. This implementation illustrates a specific design approach for the first and second sound outlet structures.
[0015] In a possible implementation of the first aspect, the first sound outlet structure includes a first sound outlet slit, and the second sound outlet structure includes a second sound outlet slit. This implementation illustrates a specific design of the first sound outlet structure and the second sound outlet structure.
[0016] In a possible implementation of the first aspect, the first sound outlet slit is shaped like a rectangle, a racetrack, or an ellipse, and the second sound outlet slit is shaped like a rectangle, a racetrack, or an ellipse. This implementation illustrates a specific design of the first and second sound outlet structures.
[0017] In a possible implementation manner of the first aspect, the first sound output structure and the second sound output structure have the same structure.
[0018] In a possible implementation of the first aspect, the first sound output structure and the second sound output structure are symmetrically arranged on the middle frame. On this basis, by symmetrically arranging the first sound output structure and the second sound output structure on the middle frame, it is beneficial to improve the stereo sound effect of the electronic device.
[0019] In one possible implementation of the first aspect, the display screen is curved on all four sides. This implementation illustrates a specific implementation of the display screen. This is due to the provision of the sound outlet structure in this application, which eliminates the need for opening holes or seams in the display screen, thereby enabling the display screen to be curved on all four sides.
[0020] In a possible implementation of the first aspect, the audio driver is a piezoelectric ceramic. This implementation shows a specific audio driver. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present application provides an electronic device, which may be a mobile terminal. The mobile terminal may be a mobile phone, a tablet computer, a laptop computer, a handheld computer, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, etc. The embodiments of the present application do not impose any particular restrictions on the specific type of the electronic device. The embodiments of the present application are described using a mobile phone as an example.
[0041] The mobile terminal can be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, a smart home device and / or a smart city device. The embodiments of the present application do not impose any special restrictions on the specific type of the electronic device.
[0042] In current mobile phones, a speaker is usually set in the middle of the phone, and the sound outlet slot at the top of the phone is close to the top of the screen. In order to ensure the normal performance of the top speaker and to ensure that the sound emitted by the top speaker is not heard by people around when holding the phone for a call, existing mobile phones generally have a small sound outlet slot at the top of the phone's display screen. Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the front structure of a mobile phone in the prior art. Figure 1 As shown in FIG, a micro-slit for sound emission is provided at the top of the display screen of the mobile phone. When a user holds the mobile phone near his ear, the sound emitted by the speaker at the top of the mobile phone can be transmitted to the user's ear through the micro-slit for sound emission at the top of the display screen.
[0043] When holding the phone close to your ear, the sound outlet slit faces your ear or tilts upward toward your ear, allowing sound to escape through the slit in the display. This reduces the risk of sound leakage from the top speaker during handheld calls. However, since the slit is located in the display, it compromises the integrity of the display. Furthermore, because the slit is very narrow, typically less than 0.5mm, it is prone to noise and can easily become blocked with long-term use, affecting the sound quality.
[0044] In the prior art, whether it is setting a "bangs" on the display screen, setting a sound structure on the "bangs", or directly making a slit on the display screen to set a sound slit, it will destroy the integrity of the display screen, making it impossible for the mobile phone display screen to achieve a full-screen design. It should be noted that the full screen in the embodiment of this application means that there are no openings or slits on the display screen, that is, it is a 100% full screen. The "water drop-shaped" screen or the screen with "bangs" in the prior art is not a 100% full screen, that is, it is not the full screen referred to in the embodiment of this application.
[0045] In order to solve the above problems, the present invention provides an electronic device. Figures 2 to 5 , Figure 2 This is a schematic diagram of the structure of an electronic device from a top perspective provided in an embodiment of the present application. Figure 3 This is a schematic diagram of the structure of an electronic device from a bottom perspective provided by an embodiment of the present application. Figure 4 This is a schematic diagram of the structure of another electronic device from a top perspective provided in an embodiment of the present application. Figure 5 An exploded diagram of another electronic device provided in an embodiment of the present application. Figure 2 and Figure 3 The difference lies in the perspective. Figure 2 and Figure 4 The difference lies in the different settings of the display screen 110. Figure 2 The display screen 110 of the electronic device 100 shown is a curved screen at the top and bottom. Figure 4 The display screen 110 of the electronic device 100 is a flat screen. Figure 5 The electronic device 100 is shown with Figure 4 The electronic device 100 shown is the same electronic device 100 . Figures 2 to 5 Except for the above differences, the other main structures of the electronic device 100 are the same.
[0046] like Figures 2 to 5 As shown, the electronic device 100 includes a display screen 110, a middle frame 120, and a back cover 130. The display screen 110 is arranged on one side of the middle frame 120, and the back cover 130 is arranged on the other side of the middle frame 120. The display screen 110, the middle frame 120, and the back cover 130 can form a closed space. Various electronic components in the electronic device 100, such as the motherboard, processor, memory, speaker, battery, etc., are all arranged in the closed space. Figure 5As shown, to facilitate securing the various electronic components within the electronic device 100, the middle frame 120 generally includes a frame 121 and a support plate 122. The support plate 122 is fixedly connected to the frame 121 and positioned between the screen and the back cover 130. Generally speaking, the display screen 110 and the back cover 130 are attached to the frame 121 of the middle frame 120, and the display screen 110 and the support plate 122 are also attached by adhesive. Electronic components such as the motherboard and battery within the electronic device 100 can be secured to the support plate 122.
[0047] like Figure 5 As shown, the electronic device 100 provided in the embodiment of the present application further includes an audio driver 180 and a speaker. Both the audio driver 180 and the speaker are disposed within the electronic device 100, i.e., within an enclosed space. The audio driver 180 is connected to the display screen 110 or the back cover 130. In the embodiment of the present application, the audio driver 180 is connected to the display screen 110. Both the audio driver 180 and the speaker can generate sound, converting corresponding information into audio information and transmitting it to the user. The sound generated by the speaker needs to be transmitted to the outside world through holes or slits. Therefore, a sound-emitting structure is provided on the body of the electronic device 100. Specifically, in the embodiment of the present application, the sound-emitting structure is provided on the middle frame 120. The audio driver 180 is connected to the display screen 110 or the back cover 130. When the audio driver 180 receives the corresponding electrical signal, it vibrates, driving the display screen 110 or the back cover 130 to vibrate, thereby emitting the corresponding sound.
[0048] In one embodiment of the present application, the audio exciter 180 is connected to the display screen 110, that is, the audio exciter 180 is connected to the back of the display screen 110. The audio exciter 180 can be made of piezoelectric ceramics. A piezoelectric ceramic sheet is an electronic sound-generating element. For example, a piezoelectric ceramic dielectric material is placed between two circular copper electrodes. When an AC audio signal is applied to the two electrodes, the piezoelectric sheet vibrates according to the signal's magnitude and frequency, producing a corresponding sound. When voltage is applied to the piezoelectric ceramic, the piezoelectric ceramic undergoes mechanical deformation as the voltage and frequency change. Because it is connected to the display screen 110, when the piezoelectric ceramic vibrates, it also causes the display screen 110 to vibrate, causing the display screen 110 to emit sound. When a user places the electronic device 100 near their ear, such as when making a phone call, the display screen 110 of the electronic device 100 is generally oriented toward the user's ear, so that the sound emitted by the display screen 110 can be heard more clearly.
[0049] Since the sound produced by the speaker needs a corresponding channel to be transmitted to the outside of the electronic device 100, in the embodiment of the present application, a sound outlet structure is provided on one end of the middle frame 120 of the electronic device 100. The sound outlet structure connects the speaker with the outside world, so that the sound produced by the speaker is transmitted to the outside world through the sound outlet structure. Figure 2 and Figure 4 As shown, the sound outlet structure is generally arranged on the middle frame 120 at the top of the electronic device 100 , and the corresponding speaker is generally also arranged on the top of the electronic device 100 .
[0050] It should be noted that the top of the electronic device 100 refers to the end located at the top when the electronic device 100 is placed vertically with the display screen 110 facing the user. Correspondingly, the end located at the bottom of the electronic device 100 is referred to as the bottom of the electronic device 100. For convenience of description, the end of the middle frame 120 located at the top of the electronic device 100 is referred to as the first end, and the end of the middle frame 120 located at the bottom of the electronic device 100 is referred to as the second end. That is, the first end and the second end of the middle frame 120 are located at opposite ends of the middle frame 120, respectively.
[0051] In the embodiment of the present application, since the electronic device 100 is provided with a speaker, a sound-emitting structure is provided on one end of the middle frame 120 as a sound channel for the speaker, allowing the sound of the speaker to be normally transmitted to the outside world. Furthermore, by providing an audio exciter 180 on the display 110 or back cover 130 of the electronic device 100, the audio exciter 180 can cause the display 110 or back cover 130 to vibrate. The sound produced by the vibration of the display 110 or back cover 130, combined with the sound produced by the speaker, can realize the audio output function of the electronic device 100.
[0052] In the embodiment of the present application, the sound emitting structure of the speaker is arranged on the middle frame 120, that is, the sound emitting structure is located on the side of the electronic device 100. Figure 2 and Figure 4 As shown, when the display screen 110 is set in the electronic device 100 of the embodiment of the present application, the display screen 110 can be set as a full screen, that is, no holes or seams are required on the display screen 110 as a sound channel for the speaker. Figure 1 The structure shown can prevent the sound slits on the display screen 110 from being blocked during long-term use. At the same time, it can maintain the integrity of the display screen 110 and improve the screen-to-body ratio of the display screen 110.
[0053] Since the display screen 110 does not need to have holes or slots to set up the sound output channel of the speaker, the display screen 110 can achieve a 100% full screen. In the embodiment of the present application, the display screen 110 can be set as a curved screen, such as Figure 2 and Figure 3 As shown, the top and bottom of the display screen 110 can be set as curved screens.
[0054] In addition, the four sides of the display screen 110 can also be set as curved screens. Figure 2 and Figure 3 In the display screen 110 shown, the screens on both sides can also be set as curved screens. The display screen 110 of the electronic device 100 adopts a four-curved screen, and the four corners of the four-curved screen all have a certain curvature. Compared with traditional dual-curved screens (the left and right sides of the screen are curved, and the upper and lower sides remain flat) or flat screens, the four-curved screen is curved on all sides. This design can provide an immersive visual experience, reduce light reflection and glare, and provide better visual effects in certain environments. The four-curved screen has a better appearance, which is conducive to improving the aesthetics of the appearance of the electronic device 100.
[0055] Of course, the display screen 110 of the electronic device 100 in the embodiment of the present application can also be as follows Figure 4 A flat screen is shown, but regardless of whether a flat screen or a curved screen is used, the display screen 110 of the electronic device 100 can be set to be a 100% full screen. That is, there are no holes or seams on the display screen 110.
[0056] refer to Figure 6 , Figure 6 A schematic diagram of the internal structure of one side of an electronic device provided in an embodiment of the present application. Figure 6 Compared to Figure 2 or Figure 4 , the back cover 130 is removed to show the internal structure of the support plate 122 on the side of the back cover 130 in the electronic device 100. Figure 6 As shown, in one embodiment of the present application, two speakers are provided in the electronic device 100. For the convenience of description, one of the speakers is referred to as the first speaker 160, and the other speaker is referred to as the second speaker. The first speaker 160 and the second speaker 170 can be fixedly connected to the support plate 122 of the middle frame 120. That is, the first speaker 160 and the second speaker 170 are both located in a closed space. Since both speakers are located in the electronic device 100, in order to ensure that the sound generated by the speakers can be normally transmitted to the user's ears. Two sound-emitting structures are provided on the electronic device 100, which are respectively referred to as the first sound-emitting structure 140 and the second sound-emitting structure 150 ( Figure 6 Not shown, please refer to Figure 3 or Figure 5). The first sound outlet structure 140 and the second sound outlet structure 150 are both disposed on the border 121 of the middle frame 120. The first sound outlet structure 140 is disposed at a first end of the middle frame 120, and the second sound outlet structure 150 is disposed at a second end of the middle frame 120. That is, the first sound outlet structure 140 is disposed on the middle frame 120 at the top of the electronic device 100, and the second sound outlet structure 150 is disposed on the middle frame 120 at the bottom of the electronic device 100.
[0057] In order to ensure that the sound of the speakers can be smoothly transmitted to the outside world through the sound-emitting structure, the sound waves of the first speaker 160 can be transmitted to the outside world through the first sound-emitting structure 140. When the first speaker 160 is set, the first speaker 160 can be placed close to the first end of the middle frame 120, which can also be understood as the first speaker 160 emitting sound through the first sound-emitting structure 140. The sound waves of the second speaker 170 can be transmitted to the outside world through the second sound-emitting structure 150. When the second speaker 170 is set, the second speaker 170 can be placed close to the second end of the middle frame 120, which can also be understood as the second speaker 170 emitting sound through the second sound-emitting structure 150.
[0058] By providing two speakers in the electronic device 100, and arranging the two speakers at both ends of the electronic device 100, sound output structures are provided at both the first end (the top of the electronic device 100) and the second end (the bottom of the electronic device 100) of the middle frame 120 of the electronic device 100, so that each speaker can transmit sound to the outside of the electronic device 100 through the corresponding sound output structure. When the electronic device 100 is in a scenario where sound is output externally, such as playing audio or video, sound can be emitted from both the top and bottom of the electronic device 100, achieving stereo sound output of the electronic device 100, which is beneficial to improving the sound output effect of the electronic device 100.
[0059] In addition, to achieve a better stereo sound effect, when setting the first sound outlet structure 140 and the second sound outlet structure 150, the first sound outlet structure 140 and the second sound outlet structure 150 can be set to be symmetrical. It should be noted that in the embodiment of the present application, the symmetry of the first sound outlet structure 140 and the second sound outlet structure 150 means that the first sound outlet structure 140 and the second sound outlet structure 150 are symmetrical about the midline of the electronic device 100 in the longitudinal direction, that is, the first sound outlet structure 140 and the second sound outlet structure are symmetrical on the electronic device 100.
[0060] It should be noted that the symmetry referred to in the embodiments of the present application may include similar symmetry and other situations. That is, on the basis that the first sound-emitting structure 140 and the second sound-emitting structure 150 are theoretically completely symmetrical, the first sound-emitting structure 140 and the second sound-emitting structure 150 may have a certain offset. For example, after the first sound-emitting structure 140 is offset to the left or right by a certain distance on the top middle frame 120, or after the second sound-emitting structure 150 is offset to the left or right by a certain distance on the bottom middle frame 120, it can also be understood that the first sound-emitting structure 140 and the second sound-emitting structure 150 are symmetrically arranged at the upper and lower ends of the electronic device 100.
[0061] For example, Figure 2 or Figure 4 As shown, the first sound outlet structure 140 is arranged in the middle position of the top middle frame 120, as shown in FIG. Figure 3 or Figure 5 As shown, the second sound outlet structure 150 is disposed on the bottom middle frame 120, but is disposed close to the left or right border 121 (not in the center of the bottom middle frame 120). In this case, it can be considered that the first sound outlet structure 140 and the second sound outlet structure 150 are symmetrically disposed at both ends of the electronic device 100.
[0062] For another example, the second sound emitting structure 150 is set in the middle position of the bottom middle frame 120, and the first sound emitting structure 140 is set on the top middle frame 120, but is set close to the left or right border 121 (not in the middle position of the top middle frame 120). At this time, it can be considered that the first sound emitting structure 140 and the second sound emitting structure 150 are symmetrically arranged at both ends of the electronic device 100. At this time, it can also be considered that the first sound emitting structure 140 and the second sound emitting structure 150 are symmetrically arranged at both ends of the electronic device 100.
[0063] That is, if the first sound emitting structure 140 is disposed on the middle frame 120 at the top of the electronic device 100, the second sound emitting structure 150 is disposed on the middle frame 120 at the bottom of the electronic device 100, and the lateral distance (the distance in the width direction of the electronic device 100) between the first sound emitting structure 140 and the second sound emitting structure 150 is less than a preset distance (for example, half the width of the electronic device 100), it can be considered that the first sound emitting structure 140 and the second sound emitting structure 150 are symmetrically (vertically) disposed at both ends of the electronic device 100. This preset distance can be set according to actual needs.
[0064] In one embodiment of the present application, Figure 2 、 Figure 4 and Figure 6 As shown, the first sound outlet structure 140 may include one or more first sound outlet holes. Figure 3 and Figure 5As shown, the second sound outlet structure 150 may include one or more second sound outlet holes. The shape of the first sound outlet hole can be set to be circular, elliptical, racetrack-shaped or regular polygonal, and the shape of the second sound outlet hole can also be circular, elliptical, racetrack-shaped or regular polygonal. For example, the first sound outlet structure 140 is composed of 5 equally spaced first sound outlet holes, and the first sound outlet holes are set to be circular. The second sound outlet structure 150 is composed of 5 equally spaced second sound outlet holes, and the second sound outlet holes are also set to be circular. The size of the first sound outlet hole is the same as the size of the second sound outlet hole.
[0065] Alternatively, the first sound outlet structure 140 may include one or more first sound outlet slits, and the second sound outlet structure 150 may include one or more second sound outlet slits. The first sound outlet slits may be rectangular, elliptical, or runway-shaped, and the second sound outlet slits may also be rectangular, elliptical, or runway-shaped. For example, the first sound outlet structure 140 may include two first sound outlet slits, each configured in a runway-shaped configuration; the second sound outlet structure 150 may include two second sound outlet slits, each configured in a runway-shaped configuration. The first sound outlet slits may be the same size as the second sound outlet slits.
[0066] It should be noted that the "track shape" in the embodiments of the present application refers to a long rectangle with two short sides connected to two semicircles, forming a shape similar to that of a standard track and field track.
[0067] In one embodiment of the present application, the first speaker 160 can be located at a position similar to the following: Figure 7 and Figure 8 , Figure 7 for Figure 4 The cross-sectional view of the electronic device 100 along the AA direction is shown. Figure 8 A schematic diagram of the internal structure of the other side of an electronic device provided in an embodiment of the present application. Figure 6 Compared to Figure 2 or Figure 4 , the display screen 110 is removed to show the internal structure of the support plate 122 on the side of the display screen 110 in the electronic device 100.
[0068] like Figure 7 As shown, the display screen 110 is disposed on one side of the support plate 122 , and the first speaker 160 is disposed on the other side of the support plate 122 . The display screen 110 can be connected to the support plate 122 by gluing. The audio exciter 180 is connected to the display screen 110 .
[0069] like Figure 7 Forehead Figure 8As shown, a notch (not labeled) is provided on the support plate 122, which is covered by the first speaker 160. This creates a cavity near the notch formed by the first speaker 160, the support plate 122, the display screen 110, and the frame 121. The cavity has a thickness equal to the thickness of the support plate 122. This cavity serves as a sound output cavity 190 for the first speaker 160, which communicates with the outside world through the first sound output structure 140.
[0070] It should be noted that if Figure 7 As shown, since the display screen 110 is connected to the support plate 122 and the first speaker 160 is connected to the other side of the support plate 122, and the speaker covers the gap, the sound cavity 190 is isolated from the space inside the electronic device 100. Since the sound cavity 190 is connected to the outside world through the first sound outlet structure 140, the sound generated by the first speaker 160 can be transmitted to the outside world through the sound cavity 190 and the first sound outlet structure 140.
[0071] In addition, the support plate 122 further includes a connecting structure 1221, such as Figure 7 and Figure 8 As shown, the thickness of the connecting structure 1221 is less than the overall thickness of the support plate 122. When the display screen 110 is bonded to the support plate 122, the display screen 110 does not contact the connecting structure 1221. The purpose of this arrangement is to allow the sound cavity 190 to communicate with the first sound output structure 140, so that the sound produced by the first speaker 160 can be transmitted to the outside world through the sound output cavity 190 and the first sound output structure 140. It should be noted that the connecting structure 1221 is part of the support plate 122, but the thickness of the connecting structure 1221 is less than the overall thickness of the support plate 122.
[0072] In order to increase the airtightness of the sound cavity 190, when connecting the first speaker 160 to the support plate 122, in order to prevent the first speaker 160 from being loosely connected to the support plate 122. The first speaker 160 and the support plate 122 are connected by a sealing gasket 101, and the first speaker 160 and the sealing gasket 101, as well as the sealing gasket 101 and the speaker can be connected by gluing. Among them, the sealing gasket 101 is an annular sealing gasket 101, and the size of the inner circle of the sealing gasket 101 can be slightly larger than the size of the notch on the support plate 122 to avoid affecting the sound of the first speaker 160 from entering the sound cavity 190. The sealing gasket 101 can be made of foam or other materials with sound insulation properties.
[0073] Since the sound of the first speaker 160 is transmitted to the outside through the sound cavity 190 and the first sound emitting structure 140, and the sound cavity 190 is isolated from other spaces inside the electronic device 100, the sound generated by the first speaker 160 and the sound generated by the second speaker 170 will not interfere with each other in the internal space of the electronic device 100. When setting the second speaker 170, you can refer to Figure 5 or Figure 6 , connect the second speaker 170 to the support plate 122, and place the second speaker 170 close to the second sound output structure 150. Specifically, align the second speaker 170 with the second sound output structure 150. The second speaker 170 can be fixed to the support plate 122 by gluing or screwing.
[0074] Through the above-mentioned setting, the sounds produced by the first speaker 160 and the second speaker 170 will not interfere with each other inside the electronic device 100, and the sound produced by the first speaker 160 can be transmitted to the outside through the first sound output structure 140 at the top of the electronic device 100, and the sound produced by the second speaker 170 can be transmitted to the outside through the second sound output structure 150 at the bottom of the electronic device 100, so that the electronic device 100 has a good stereo effect.
