[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] Reference Figure 1 to Figure 2 , which shows a partial structural diagram of an electronic device in the related art, such as Figure 1 to Figure 2 As shown, the speaker assembly is an independent structural member arranged in the electronic device. The speaker assembly includes an upper cover 7 and a lower cover 8 connected by welding. A closed cavity is formed between the upper cover 7 and the lower cover 8. The speaker unit 2 is arranged in the cavity to form a front sound cavity and a rear sound cavity that are independent of each other, thereby avoiding sound short circuit and obtaining better sound effects. Since the structural form of the speaker assembly is relatively fixed, the spatial impact on the electronic device is also relatively fixed. With the development of lightweight electronic devices, the stacking space of the speaker assembly position has gradually become a bottleneck for the lightweight setting of electronic devices. Specifically, there is a serious contradiction between the speaker assembly and the battery capacity. Increasing the cavity volume of the speaker assembly can improve the sound quality but will occupy the battery volume, affecting the endurance of the electronic device. Increasing the battery volume can improve the endurance of the electronic device but will lose the cavity volume, affecting the sound quality of the electronic device.
[0026] An embodiment of the present application provides an electronic device, which is described in detail below with reference to the accompanying drawings.
[0027] Reference Figures 3 to 6 , shows a partial structural diagram of an electronic device provided in an embodiment of the present application, such as Figures 3 to 6As shown, the present application provides an electronic device, including: a shell 3, the shell 3 is provided with a accommodating cavity; a frame 1, the frame 1 is arranged in the accommodating cavity, and the frame 1 is provided with a first opening; a speaker unit 2, the speaker unit 2 is connected to the first opening; wherein the shell 3, the frame 1 and the speaker unit 2 enclose a first sound cavity.
[0028] In the embodiment of the present application, since the housing 3 is provided with a receiving cavity, the frame 1 is provided in the receiving cavity, and the first opening is provided in the frame 1 and the speaker unit 2 is connected to the first opening. In this way, after the electronic device is assembled, the housing 3, the frame 1 and the speaker unit 2 can enclose and form a first sound cavity. Compared with providing a separate speaker module between the frame 1 and the housing 3, the electronic device of the present application can eliminate the lower cover 8 of the speaker module, thereby reducing the space occupied in the thickness direction of the electronic device, which is conducive to the thin and light design of the electronic device.
[0029] It should be noted that in order to improve the sealing of the first sound cavity, the speaker unit 2 of the embodiment of the present application is sealed and connected to the first opening. Among them, the sealed connection between the speaker unit 2 and the first opening can be achieved by a sealed connection between the speaker unit 2 and the frame 1 with the first opening. Specifically, the speaker unit 2 and the frame 1 can be tightly bonded together by dispensing glue on the surface of the frame 1 around the first opening to achieve a sealed connection between the speaker unit 2 and the frame 1. In addition, the embodiment of the present application does not limit the specific structure of the first opening. For example, Figure 3 As shown, in one embodiment, the first opening is a through hole provided through the frame 1. Figure 4 As shown, in another embodiment, the first opening is not a through hole penetrating the frame body 1 , but only a through hole penetrating a portion of the frame body 1 , namely, the second slot wall 121 .
[0030] It should be noted that the electronic device includes but is not limited to a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device (such as a watch or a bracelet), an augmented reality (AR) glasses, an AR helmet, a virtual reality (VR) glasses, a VR helmet, a mixed reality (MR) glasses or an MR helmet, etc. In addition, the speaker unit 2 of the embodiment of the present application refers only to the sound unit in the speaker module or the speaker system, and does not include the sound cavity.
[0031] In some optional embodiments of the present application, the housing 3 includes: a cover plate 31 and a side plate 32; the cover plate 31 is arranged on one side of the frame 1 in the thickness direction; the side plate 32 is connected to the peripheral side of the cover plate 31, and the side plate 32 and the cover plate 31 are enclosed to form a receiving cavity; wherein the cover plate 31, the frame 1 and the speaker unit 2 are enclosed to form a first sound cavity. That is, the first sound cavity is enclosed by the speaker unit 2 and the structural parts of the electronic device itself (the cover plate 31 and the frame 1), and the lower cover 8 of the speaker module can be eliminated, thereby reducing the space occupied in the thickness direction of the electronic device, which is conducive to the lightweight design of the electronic device.
[0032] In practical applications, if the first sound cavity, i.e., the rear sound cavity, is not well sealed, the sound waves propagating backwards from the speaker unit 2 may cancel or interfere with the sound waves propagating forwards, resulting in a short circuit of the sound and a decrease in sound quality. Based on this, in some optional embodiments of the present application, a first groove 11 is provided on one side of the frame 1 close to the cover plate 31, and the first groove 11, the cover plate 31, and the speaker unit 2 enclose a first sound cavity; the first groove 11 includes a first groove wall 111, and the first groove wall 111 is sealed and connected to the cover plate 31.
[0033] In the embodiment of the present application, on the one hand, since the first groove 11 is provided, the first sound cavity is enclosed by the first groove 11, the cover plate 31 and the speaker unit 2, so that the volume of the first sound cavity can be adjusted by adjusting the shape and / or size of the first groove 11, which is conducive to improving the design flexibility of the sound cavity structure. On the other hand, since the first groove wall 111 of the first groove 11 is sealed and connected to the cover plate 31, the sealing of the first sound cavity can be improved, which is conducive to improving the sound quality of the electronic device.
[0034] It should be noted that the woofer speaker unit 21 and the tweeter speaker unit 22 have different requirements for the volume of the first sound cavity, that is, the rear sound cavity. Specifically, the woofer speaker unit 21 has a relatively high requirement for the volume of the first sound cavity, while the tweeter speaker unit 22 has a relatively low requirement for the volume of the first sound cavity. That is, the volume of the first sound cavity of the woofer speaker unit 21 usually needs to be greater than the volume of the first sound cavity of the tweeter speaker unit 22. Based on this, if Figure 6 As shown, the volume of the first groove 11 corresponding to the woofer speaker unit 21 is generally greater than the volume of the first groove 11 corresponding to the tweeter speaker unit 22 .
[0035] In some optional embodiments of the present application, the electronic device further includes: a sealing adhesive 6 , which is disposed between the first groove wall 111 and the cover plate 31 and is bonded to the first groove wall 111 and the cover plate 31 , respectively.
[0036] In the embodiment of the present application, by providing a sealing adhesive 6 between the first groove wall 111 and the cover plate 31, the first groove wall 111 and the cover plate 31 can be tightly bonded together, thereby improving the sealing of the first sound cavity, which is beneficial to improving the sound quality of the electronic device. It can be understood that the sealing adhesive 6 is provided along the circumference of the first groove wall 111, so that the first groove wall 111 and the cover plate 31 can be sealed everywhere at the contact position, thereby improving the sealing of the first sound cavity as much as possible.
[0037] It should be noted that the sealing adhesive 6 includes but is not limited to AB glue. For example, the AB glue can be epoxy resin AB glue, polyurethane AB glue, acrylic AB glue, silicone AB glue, etc.
[0038] In some optional embodiments of the present application, the electronic device also includes: a display screen 4 and a seal 5; the display screen 4 is connected to the side of the side panel 32 facing away from the cover plate 31 and has a first gap with the frame 1; the seal 5 is arranged in the first gap and is located on at least part of the circumference of the speaker unit 2; wherein the display screen 4, the seal 5, the frame 1, the speaker unit 2 and the side panel 32 enclose a second sound cavity.
[0039] In the embodiment of the present application, since a seal 5 is provided, the seal 5 is provided in the first gap between the display screen 4 and the frame 1 and is located at least partially around the speaker unit 2. In this way, the seal 5, the display screen 4, the frame 1, the speaker unit 2 and the side panel 32 can be enclosed to form a second sound cavity (i.e., the front sound cavity). On the one hand, the second sound cavity can make full use of the first gap between the display screen 4 and the frame 1, which is beneficial to saving space in the thickness direction of the electronic device. On the other hand, compared to providing a separate speaker module between the frame 1 and the housing 3, the electronic device of the present application can cancel the upper cover 7 of the speaker module, thereby further reducing the space occupied in the thickness direction of the electronic device, which is beneficial to the lightweight design of the electronic device.
[0040] It should be noted that the material of the seal 5 can be foam (such as polyurethane foam), silicone or other materials with sealing effect, which is not limited here, and those skilled in the art can choose according to actual needs. In one embodiment, the seal 5 is a foam seal, and the foam has the characteristics of high density, low hardness and high resilience. The high density can improve the sealing effect between the display screen 4 and the frame 1, the low hardness can avoid damage caused by hard contact between the display screen 4 and the seal 5, and the high resilience makes the seal 5 have good pressure resistance and recovery performance to prevent the user from pressing the display screen 4. The pressure is too great and the seal 5 is damaged, affecting the sealing effect, and the display screen 4 can be quickly reset after the user stops pressing the display screen 4.
[0041] In some optional embodiments of the present application, the side panel 32 is provided with a sound outlet 322, and the sound outlet 322 is connected to the second sound cavity so that the sound of the second sound cavity is transmitted to the outside of the electronic device. That is, by providing the sound outlet 322, the sound of the second sound cavity can be smoothly transmitted to the user's ears.
[0042] In some optional embodiments of the present application, the side panel 32 close to the speaker unit 2 is a first side panel 321 , the seal 5 is provided with a second opening at a position corresponding to the first side panel 321 , and a second gap is provided between the second opening and the first side panel 321 .
[0043] In the case where the sound outlet 322 is arranged on the first side panel 321, by arranging the second opening at a position corresponding to the first side panel 321, the sound of the second sound cavity can be transmitted to the sound outlet 322 through the second opening, and then transmitted to the outside of the electronic device through the sound outlet 322. In addition, since there is a second gap between the second opening and the first side panel 321, in this case, the second sound cavity is not completely sealed, and part of the sound of the second sound cavity can diffuse through the second gap to the first gap between the display screen 4 and the frame 1, that is, part of the sound is transmitted in the electronic device. This non-completely sealed second sound cavity is suitable for a woofer speaker unit 21 with low directivity requirements, which can enhance the low-frequency performance and help improve the user's bass listening experience. Among them, the woofer speaker unit 21 refers to a speaker unit 2 with a sound frequency of 20Hz to 200Hz, which is responsible for the output of low-frequency sounds.
[0044] In one embodiment, if Figure 5 As shown, the seal 5 is U-shaped, and the U-shaped seal 5 is arranged on the peripheral side of the speaker unit 2, and the second opening faces the first side plate 321. Specifically, except for one side close to the first side plate 321, the other three sides of the speaker unit 2 are blocked by the U-shaped seal 5, so that a U-shaped sound guide channel can be formed between the U-shaped seal 5 and the speaker unit 2, so that the sound of the second sound cavity can be auxiliaryly guided to the sound outlet hole 322.
[0045] In some optional embodiments of the present application, a second groove 12 is provided in the frame 1, and the second groove 12 is communicated with the first opening; wherein the second groove 12, the speaker unit 2 and the side panel 32 enclose a second sound cavity.
[0046] In the embodiment of the present application, since the second groove 12 is arranged in the frame 1, that is, a groove is directly processed in the frame 1. In this way, when the frame 1 and the shell 3 are assembled, the second groove 12 can enclose the speaker unit 2 and the side panel 32 to form a completely sealed second sound cavity, so that the sound of the second sound cavity can be almost completely transmitted to the outside of the electronic device through the sound outlet 322 located on the side panel 32. This completely sealed second sound cavity is suitable for tweeter units 22 with high directivity requirements, and can improve the clarity and purity of the sound. Among them, the tweeter unit 22 refers to a speaker unit 2 with a sound frequency of more than 2kHz, which is responsible for the output of high-frequency sound.
[0047] It should be noted that the "complete sealing" in the embodiment of the present application is not absolute sealing, but is only relative to "incomplete sealing", that is, the sealing performance of complete sealing is better than that of incomplete sealing.
[0048] In some optional embodiments of the present application, the second groove 12 includes a second groove wall 121 close to the first sound cavity, and the first opening is opened in the second groove wall 121. In this way, by connecting the speaker unit 2 to the first opening, the first sound cavity and the second sound cavity can be made independent of each other and the sound emitted by the speaker unit 2 can be smoothly transmitted to the outside of the electronic device through the second sound cavity, thereby obtaining better sound effects. In addition, when the first opening is opened in the second groove wall 121 and the speaker unit 2 is connected to the first opening, the speaker unit 2 can be located in the first sound cavity with a larger volume, that is, the first sound cavity can be used to install the speaker unit 2, thereby reducing the space occupied by the speaker unit 2 in the thickness direction of the electronic device, which is conducive to the lightweight design of the electronic device.
[0049] In some optional embodiments of the present application, the frame 1 is further provided with a mounting groove 13, which is provided in the frame 1 and corresponds to the first opening; at least a portion of the speaker unit 2 is embedded in the mounting groove 13 and is sealed to the mounting groove 13. Specifically, the mounting groove 13 is provided on one side of the frame 1 close to the cover plate 31.
[0050] In the embodiment of the present application, by providing the mounting groove 13 at the corresponding position of the first opening, the installation and positioning of the speaker unit 2 can be assisted, which is beneficial to improving the assembly accuracy and assembly efficiency of the speaker unit 2 and the frame 1. In addition, since the sound output surface of the speaker unit 2 is facing the second sound cavity, the sealed connection between the speaker unit 2 and the mounting groove 13 can make the first sound cavity and the second sound cavity independent of each other, so that the sound emitted by the sound output surface is completely transmitted to the second sound cavity.
[0051] In one embodiment, the mounting groove 13 is formed by providing a protrusion extending toward the cover plate 31 on at least part of the circumference of the first opening. The mounting groove 13 includes a bottom wall and a side wall. By dispensing glue on the bottom wall and / or the side wall, the speaker unit 2 and the mounting groove 13 can be tightly bonded together to achieve a sealed connection between the speaker unit 2 and the mounting groove 13. It can be understood that compared with the related art of fixing the speaker unit 2 by screw locking, the embodiment of the present application uses a bonding method to save space and is conducive to increasing the volume of the first sound cavity and the second sound cavity.
[0052] When the sound cavity structure of the embodiment of the present application is adopted, after testing, when the volume of the first sound cavity and the second sound cavity remains unchanged, the space in the thickness direction of the electronic device can be saved by 0.55mm, which is conducive to the thinness of the electronic device. When the thickness of the electronic device remains unchanged, the volume of the first sound cavity can be increased, so that part of the space can be transferred to the battery on the basis of meeting the sound quality, that is, the volume of the battery can be appropriately increased, which is conducive to improving the endurance of the electronic device.
[0053] In summary, the electronic device provided by the embodiments of the present application has at least the following advantages:
[0054] In the embodiment of the present application, since the housing is provided with a receiving cavity, the frame is provided in the receiving cavity, and a first opening is provided in the frame and the speaker unit is connected to the first opening. In this way, after the electronic device is assembled, the housing, the frame and the speaker unit can enclose and form a first sound cavity. Compared with providing a separate speaker module between the frame and the housing, the electronic device of the present application can eliminate the lower cover of the speaker module, thereby reducing the space occupied in the thickness direction of the electronic device, which is conducive to the lightweight design of the electronic device.
