Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] Mobile phones and other electronic devices have brought many conveniences to users' lives and work, and with the continuous advancement of technology, the functions of mobile electronic devices have become more and more diverse. Generally, mobile phones usually have the functions of taking pictures and playing audio, and affected by the trend of increasing size of camera modules, the relatively large size of the ring body provides a space basis for the installation of a high-power first speaker, so that electronic devices can adopt the solution of back-sound output to improve the overall sound quality of electronic devices.

[0003] However, when using the back-side sound output solution, when the mobile phone is placed flat on the table, since the camera module is protruding relative to the back cover, a relatively narrow gap will be formed between the camera module and the table top. This results in a relatively small distance between the sound outlet located at the ring body and the table top, which in turn causes a large number of reflected sound waves to be generated between the table top and the camera module, which will have a significant adverse effect on the sound quality of the electronic device. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device to solve the problem that when the electronic device currently using the back sound output solution is placed flat on the table, a large number of reflected sound waves generated between the table and the camera module will have a significant adverse effect on the sound quality of the electronic device.

[0005] The embodiment of the present application discloses an electronic device, which includes a back cover, a first speaker and a camera module, wherein: The rear cover is provided with a first through hole, the first speaker is installed in the first through hole, the camera module is protrudingly arranged on one side of the rear cover, and the camera module is provided with a sound outlet hole and a sound outlet channel, the sound outlet hole is connected with the first speaker through the sound outlet channel, and the sound outlet direction of the sound outlet hole is toward the side of the rear cover where the camera module is located; The electronic device comprises a first side and a second side opposite to each other along its length direction, the minimum distance between the first side and the camera module is smaller than the minimum distance between the second side and the camera module, and at least a portion of the sound outlet is disposed close to the first side. The embodiment of the present application discloses an electronic device, wherein a first through hole is provided on the back cover, and a first speaker is installed in the first through hole, a camera module is protrudingly provided on one side of the back cover, and a sound outlet hole on the camera module is connected to the first speaker through a sound outlet channel, so that the sound waves emitted by the speaker can be transmitted to the outside of the electronic device through the first through hole, the sound outlet channel and the sound outlet hole. The sound outlet direction of the sound outlet hole is toward the side of the back cover where the camera module is located, so that the electronic device disclosed in the embodiment of the present application has the ability to emit sound from the back, and the sound quality of the electronic device is relatively good.

[0006] At the same time, in the first side and the second side of the electronic device that are opposite to each other along its length direction, the minimum distance between the camera module and the first side is relatively smaller, so that when the user holds the electronic device for use or shooting, the user's hand is not easy to contact and block the camera module, preventing the camera module from being contaminated, etc., thereby improving the shooting effect of the electronic device. Based on this, when the back cover of the electronic device is supported on a reflective surface such as a desktop, the position of the camera module close to the second side can be supported on the reflective surface. In this case, by setting at least a part of the sound outlet close to the first side of the electronic device, the distance between at least a part of the sound outlet and the reflective surface is relatively large, which can reduce the noise effect generated by the sound waves emitted from the sound outlet between the reflective surface and the camera module, thereby making the sound quality of the electronic device in the aforementioned posture relatively good.

DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0010] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0011] like Figure 1-Figure 11 As shown, the embodiment of the present application discloses an electronic device, which can be a mobile phone or a tablet computer, etc. The electronic device includes a back cover 100, a first speaker 210 and a camera module 300. Of course, the electronic device can also include other devices such as a display screen 700 and a battery.

[0012] The back cover 100 is provided with a first through hole 101, so that the sound waves emitted by the first speaker 210 can be transmitted to the outside of the electronic device through the first through hole 101. To this end, the first speaker 210 is installed in the first through hole 101. Optionally, a part of the first speaker 210 can be embedded in the first through hole 101, or the first speaker 210 can be located on the inner side of the back cover 100, that is, the first speaker 210 is located inside the electronic device. In this case, by providing other devices such as a sealing ring between the first speaker 210 and the back cover 100, it can also be ensured that the sound waves emitted by the first speaker 210 can be transmitted to the outside of the electronic device through the first through hole 101, and basically no sound leakage will occur. Based on the shape and size of the first speaker 210, the shape and size of the first through hole 101 can be designed accordingly.

[0013] The camera module 300 is used to provide a shooting function. In order to make the thickness at other positions in the electronic device relatively small while making the shooting capability of the camera module 300 relatively strong, in the electronic device, the camera module 300 can be protruded on one side of the back cover 100, so that only the thickness of the area where the camera module 300 is located in the electronic device is relatively large, while for other areas in the electronic device, the thickness is still relatively small, which can also make the overall lightness and thinness of the electronic device relatively good.

[0014] In the embodiment of the present application, the camera module 300 may be provided with a plurality of lens groups. Usually, the appearance structure of each lens group is generally circular, so that the camera module 300 still has unoccupied space between the plurality of lens groups. The aforementioned space can be used as the sound output space of the first speaker 210, and the size of the first speaker 210 can be relatively large, so that the sound quality of the first speaker 210 and the entire electronic device is relatively good.

[0015] To this end, in the embodiment of the present application, the camera module 300 is also located as a whole in the area where the first through hole 101 in the back cover 100 is located, and in order to ensure that the sound waves emitted by the first speaker 210 can still be transmitted normally outside the electronic device, the camera module 300 is also provided with a sound outlet hole 301 and a sound outlet channel 302, and the sound outlet hole 301 is connected to the first speaker 210 through the sound outlet channel 302. It should be noted that the sound outlet channel 302 is connected with the first speaker 210, which means that the sound outlet channel 302 is connected with the space where the sound outlet side of the first speaker 210 is located. As described above, the first speaker 210 can be located on the inner side of the back cover 100, and a sealing ring and other structures are provided between the first speaker 210 and the back cover 100, so that the space enclosed between the sound outlet side of the first speaker 210 and the first through hole 101 can be used as the sound cavity 501 of the first speaker 210. In this case, the sound outlet channel 302 can be connected with the first through hole 101, that is, it is considered that the sound outlet channel 302 and the first speaker 210 are connected to each other. In addition, the sound outlet hole 301 is a structure in the camera module 300 that is directly connected to the outside of the electronic device. It can be formed on the outer surface of the camera module 300 and is connected to the sound outlet channel 302, ensuring that the sound waves emitted by the first speaker 210 can be transmitted to the outside of the electronic device through the first through hole 101, the sound outlet channel 302 and the sound outlet hole 301.

[0016] At the same time, in order to form a back sound outlet solution, in the electronic device disclosed in the embodiment of the present application, the sound outlet direction of the sound outlet hole 301 is toward the side of the back cover 100 where the camera module 300 is located. Specifically, the axial direction of the sound outlet hole 301 can be parallel to the thickness direction of the back cover 100. In this case, the sound waves transmitted through the sound outlet hole 301 can be gradually propagated in the direction away from the back cover 100 along the thickness direction of the back cover 100. Alternatively, the axial direction of the sound outlet hole 301 can also be tilted relative to the thickness direction of the back cover 100. In this case, the axial direction of the sound outlet hole 301 still has a component along the thickness direction of the back cover 100, so that a part of the sound waves transmitted through the sound outlet hole 301 can also be gradually propagated in the direction away from the back cover 100 along the thickness direction of the back cover 100. It should be noted that in the embodiment of the present application, along the thickness direction of the back cover 100, the sound hole 301 gradually moves away from the back cover 100 from the inside to the outside, or in other words, in the process of the sound waves being transmitted to the outside of the electronic device through the sound hole 301, the sound waves gradually move away from the back cover 100.

[0017] As described above, the sound hole 301 is located on the camera module 300, and the camera module 300 is protruded on one side of the back cover 100. Based on this, in order to prevent the sound waves emitted from the sound hole 301 from being reflected between the camera module 300 and the reflective surface 800 when the side of the electronic device where the back cover 100 is located is placed on a reflective surface 800 such as a desktop, thereby generating noise that adversely affects the sound quality of the electronic device, in an embodiment of the present application, the position of the sound hole 301 on the camera module 300 can be designed to increase the distance between the sound hole 301 and the reflective surface 800 in the electronic device in the aforementioned posture, thereby minimizing the sound quality of the electronic device in the aforementioned posture.

[0018] In detail, the electronic device is usually a rectangular structure. To this end, the electronic device may include a first side 410 and a second side 420 that are opposite to each other along its length direction. More intuitively, the first side 410 and the second side 420 may be the top and bottom sides of the electronic device, wherein, when the electronic device is in an upright state or a handheld state, the surface of the electronic device that is located at the top as a whole is the first side 410 (or top side), and the surface of the electronic device that is located at the bottom as a whole is the second side 420 (or bottom side).

[0019] At the same time, in order to prevent the user's hand from touching or blocking the camera module 300 when the user is using or taking pictures with a handheld electronic device, thereby causing the outer surface of the camera module 300 to be contaminated or the shooting work to be unable to be completed normally, during the process of laying out the camera module 300, the camera module 300 as a whole can be made closer to the first side edge 410 (or top edge) of the electronic device. In this case, the user can use or take pictures through the lower half of the handheld electronic device, thereby improving the shooting effect of the camera module 300.

[0020] That is, in the embodiment of the present application, in the length direction of the electronic device, the minimum distance between the first side 410 and the camera module 300 is smaller than the minimum distance between the second side 420 and the camera module 300, wherein the minimum distance between the first side 410 and the camera module 300 is generally the distance between the first side 410 and the upper edge of the camera module 300, and correspondingly, the minimum distance between the second side 420 and the camera module 300 is generally the distance between the second side 420 and the lower edge of the camera module 300.

[0021] When the above technical solution is adopted, when the back cover 100 of the electronic device is supported on the reflective surface 800, the support effect generated by the camera module 300 protruding from the back cover 100 makes the position of the camera module 300 farthest from the first side 410 in the aforementioned length direction (i.e. the aforementioned lower edge) contact and support each other with the reflective surface 800, while the position of the camera module 300 closest to the first side 410 in the aforementioned length direction (i.e. the aforementioned upper edge) is spaced from the reflective surface 800, and the distance between the camera module 300 and the reflective surface 800 gradually increases in the direction from the aforementioned lower edge to the aforementioned upper edge and parallel to the aforementioned length direction.

[0022] Based on this, in the embodiment of the present application, in order to maximize the distance between the sound outlet hole 301 and the reflective surface 800, at least a portion of the sound outlet hole 301 can be arranged close to the first side edge 410. In other words, in the embodiment of the present application, at least a portion of the sound outlet hole 301 can be arranged close to the upper edge of the camera module 300 as much as possible, which can appropriately increase the distance between at least part of the sound outlet hole 301 and the reflective surface 800, so that the sound quality of the first speaker 210 is relatively high.

[0023] In more detail, in the embodiment of the present application, along the aforementioned length direction, the position of the camera module 300 closest to the first side 410 may be the first point, and the position of the camera module 300 farthest from the first side 410 may be the second point, that is, the first point is a point in the upper edge of the camera module 300, and the second point is a point in the lower edge of the camera module 300. The midpoint of the line between the first point and the second point may be the dividing point, and the straight line passing through the aforementioned dividing point and perpendicular to the aforementioned length direction and thickness direction may divide the camera module 300 into two parts, and the one of the aforementioned two parts close to the first side 410 may be the first part, and correspondingly, the one close to the second side 420 may be the second part. In the embodiment of the present application, at least a part of the sound outlet 301 is located in the first part.

[0024] The embodiment of the present application discloses an electronic device, wherein the back cover 100 is provided with a first through hole 101, and the first speaker 210 is installed in the first through hole 101, the camera module 300 is protrudingly arranged on one side of the back cover 100, and the sound outlet hole 301 on the camera module 300 is connected with the first speaker 210 through the sound outlet channel 302, so that the sound waves emitted by the speaker can be transmitted to the outside of the electronic device through the first through hole 101, the sound outlet channel 302 and the sound outlet hole 301. Among them, the sound outlet direction of the sound outlet hole 301 is toward the side of the back cover 100 where the camera module 300 is located, so that the electronic device disclosed in the embodiment of the present application has the ability to emit sound from the back, so that the sound quality of the electronic device is relatively good.

[0025] At the same time, in the first side 410 and the second side 420 of the electronic device that are opposite to each other along the length direction thereof, the minimum distance between the camera module 300 and the first side 410 is relatively smaller, so that when the user holds the electronic device for use or shooting, the user's hand is not easy to contact and block the camera module 300, and the camera module 300 is prevented from being stained, etc., thereby improving the shooting effect of the electronic device. Based on this, when the back cover 100 of the electronic device is supported on a reflective surface 800 such as a desktop, the position of the camera module 300 close to the second side 420 can be supported on the reflective surface 800. In this case, by making at least a part of the sound outlet 301 close to the first side 410 of the electronic device, the distance between at least a part of the sound outlet 301 and the reflective surface 800 is relatively large, which can reduce the noise effect generated by the sound waves emitted from the sound outlet 301 between the reflective surface 800 and the camera module 300, thereby making the sound quality of the electronic device in the aforementioned posture relatively good.

[0026] As described above, the camera module 300 may include a plurality of lens groups. More specifically, the camera module 300 may also include a ring body 310, which is a closed ring structure. The ring body 310 is arranged around the plurality of lens groups. The ring body 310 may generally be formed of a material with relatively strong structural strength and wear resistance such as metal, so as to provide a relatively good protective effect for the plurality of lens groups. In order to make the assembly stability between the lens group and the back cover 100 relatively higher, in the embodiment of the present application, the camera module 300 may also include a mounting portion 320, and the mounting portion 320 is fixedly connected to the inner side of the ring body 310, and the mounting portion 320 is provided with a lens avoidance hole 304, and the lens avoidance hole 304 is used to avoid the lens group, so that the light outside the electronic device can pass through the lens avoidance hole 304 and be incident on the lens group to form a corresponding image. In the case where the number of lens groups is multiple, the lens avoidance hole 304 may also be multiple, and each lens avoidance hole 304 may generally be a circular structure. A portion of the lens group can be accommodated in the lens avoidance hole 304 , so that the lens group can form an assembly relationship with the mounting portion 320 , thereby improving the assembly stability of the lens group and the back cover 100 .

[0027] Based on the above-mentioned embodiment of the present application, the sound hole 301 can be located on the ring body 310, that is, the ring body 310 is provided with the sound hole 301, and correspondingly, the mounting portion 320 can be provided with a sound outlet channel 302, so that the sound waves emitted by the first speaker 210 can still be transmitted from the sound hole 301 to the outside of the electronic device through the sound outlet channel 302. That is, in the embodiment of the present application, the sound hole 301 is located on the side of the camera module 300 as a whole. In this case, in order to ensure that the sound waves transmitted through the sound hole 301 can still propagate in the direction away from the back cover 100 along the thickness direction of the back cover 100, as shown in the figure, the axial direction of the sound hole 301 can be tilted relative to the thickness direction of the back cover 100, that is, the sound hole 301 is an inclined hole structure.

[0028] In order to further improve the sound quality of the back sound, in another embodiment of the present application, the axial direction of the sound hole 301 can be parallel to the thickness direction of the back cover 100, and in order to ensure that the sound output area of ​​the sound hole 301 can meet the demand, the sound hole 301 can be made into a slit-like structure as a whole.

[0029] In detail, the camera module 300 includes a ring body 310 and a mounting portion 320, and the mounting portion 320 is provided with a lens avoidance hole 304 and a sound outlet channel 302. In the embodiment of the present application, the camera module 300 also includes a packaging cover 330, which covers the outer side of the lens group, that is, the packaging cover 330 is arranged at the end of the ring body 310 away from the rear cover 100 to provide protection for the lens group. The packaging cover 330 is usually formed of a material with relatively high light transmittance, hardness and wear resistance, such as glass or resin.

[0030] Among them, the mounting portion 320 and the packaging cover 330 are both fixedly connected to the inner side of the ring body 310 of the closed ring structure, and the mounting portion 320 is located between the packaging cover 330 and the back cover 100, that is, the mounting portion 320 arranged on the inner side of the ring body 310 is arranged close to the back cover 100, and the end of the ring body 310 away from the back cover 100 can be extended to the side of the mounting portion 320 away from the back cover 100, so that the ring body 310 forms an outward protruding edge relative to the mounting portion 320. In this case, the packaging cover 330 can be embedded in the aforementioned outward protruding edge, and the surfaces of the packaging cover 330 and the ring body 310 on one side away from the back cover 100 are in a state of being flush with each other. That is, in the embodiment of the present application, the packaging cover 330 can be fixedly connected to the inner wall of the ring body 310, or the packaging cover 330 can also be fixedly connected to the mounting portion 320 to achieve the purpose of being relatively fixed to the ring body 310. Specifically, in a specific embodiment of the present application, a double-sided tape 340 may be used to fix the packaging cover 330 and the mounting portion 320 together.

[0031] Based on the above structure of the camera module 300, in order to make the axial direction of the formed sound hole 301 parallel to the thickness direction of the back cover 100, a first avoidance gap 331 can be provided at the edge of the packaging cover 330 close to the first side edge 410, and after the packaging cover 330 is installed on the inner side of the ring body 310, the first avoidance gap 331 and the inner wall of the ring body 310 form the sound hole 301. The axial direction of the sound hole 301 formed by the above method is parallel to the thickness direction of the back cover 100, thereby improving the sound effect of the back side of the electronic device.

[0032] As described above, the first speaker 210 can be arranged on the inner side of the back cover 100, that is, the first speaker 210 can be located as a whole on the side of the back cover 100 away from the camera module 300. In order to increase the internal space of the electronic device, during the process of assembling the electronic device, the first speaker 210 can be embedded in the first through hole 101, thereby reducing the size of the first speaker 210 located inside the electronic device and expanding the internal installation space of the electronic device.

[0033] Accordingly, in order to ensure that the first speaker 210 can still form a sound cavity 501 normally with other devices, and the sound waves emitted by it can be transmitted outside the electronic device, in the embodiment of the present application, the mounting portion 320 can be further provided with a accommodating cavity 303, and the first through hole 101 and the sound outlet channel 302 can be connected to the accommodating cavity 303. In this case, the accommodating cavity 303 provided by the mounting portion 320 can be used as the sound cavity 501 of the first speaker 210. Specifically, the side wall of the accommodating cavity 303 in the mounting portion 320 can be arranged around the first speaker 210, thereby forming the sound cavity 501 of the first speaker 210, and then the sound waves emitted by the first speaker 210 can pass through the accommodating cavity 303, the sound outlet channel 302 and the sound outlet hole 301 in sequence, and be transmitted outside the electronic device.

[0034] In the above embodiment, the portion of the accommodating cavity 303 facing the first through hole 101 may have side walls, that is, except for the position in the accommodating cavity 303 that is connected to the first through hole 101 and the sound outlet channel 302, the other regions are provided with side walls. In another embodiment of the present application, in order to reduce the difficulty of processing the accommodating cavity 303, the accommodating cavity 303 may be provided through the mounting portion 320 along the thickness direction of the rear cover 100. In this case, in order to ensure that the first speaker 210 can still form a complete sound cavity 501, the packaging cover 330 in the camera module 300 may be provided to seal the end of the accommodating cavity 303 away from the rear cover 100. That is, during the process of installing the packaging cover 330, the packaging cover 330 and the ring body 310 are relatively fixed, and the packaging cover 330 and the mounting portion 320 are also sealed and connected, thereby achieving the purpose of sealing the opening of one end of the accommodating cavity 303, and then the side wall of the accommodating cavity 303 in the mounting portion 320 and the packaging cover 330 can together form the sound cavity 501 of the first speaker 210.

[0035] In another embodiment of the present application, in order to make the reliability of the sound cavity 501 of the first speaker 210 relatively higher, the electronic device may further include a bracket 500, and the bracket 500 includes a substrate 510 and a protrusion 520, and the protrusion 520 is fixedly connected to the substrate 510. More specifically, the two can be formed by integral injection molding using materials such as plastic. Among them, the substrate 510 is fixedly connected to the side of the back cover 100 away from the camera module 300, and a part of the protrusion 520 can extend into the accommodating cavity 303 through the first through hole 101. At the same time, the substrate 510 is also provided with a second through hole 511, and the first speaker 210 is installed in the second through hole 511, and the protrusion 520 includes a side wall 521 and a top wall 522. In this case, the first speaker 210, the side wall 521 and the top wall 522 can enclose the sound cavity 501 of the first speaker 210, and then the sound cavity 501 is independently formed using the bracket 500, which can improve the reliability of the sound cavity 501.

[0036] Of course, in order to ensure that the sound waves emitted by the first speaker 210 can be transmitted from the aforementioned sound cavity 501 to the outside of the electronic device, in the embodiment of the present application, a second avoidance gap 523 is further provided on the side wall 521, and in order to shorten the propagation path of the sound waves and reduce the reflection and refraction of the sound waves, the second avoidance gap 523 is arranged close to the first side edge 410, that is, the second avoidance gap 523 and the sound outlet hole 301 are both located on the same side of the accommodating cavity 303. Based on this, the sound cavity 501 can be connected with the sound outlet channel 302 through the second avoidance gap 523. Specifically, in the process of forming the second avoidance gap 523, the sound outlet area of ​​the second avoidance gap 523 can be made larger than the sound outlet area of ​​the sound outlet channel 302 and the sound outlet hole 301, so as to prevent the first avoidance gap 331 from being too small in size and having an adverse effect on the sound quality of the first speaker 210.

[0037] Furthermore, in the embodiment of the present application, the electronic device may further include a first supporting protrusion 351, which is fixedly connected to the side of the ring body 310 in the camera module 300 away from the rear cover 100, and the first supporting protrusion 351 is arranged close to the second side edge 420. Specifically, the first supporting protrusion 351 may be close to or located at the lower edge of the ring body 310 (i.e., the edge of the ring body 310 close to the second side edge 420), so that the first supporting protrusion 351 can provide a relatively large tilt support angle for the entire electronic device when the protruding size is relatively small, so that the distance between the sound outlet 301 and the reflecting surface 800 is relatively larger. Of course, the specific protruding size of the first supporting protrusion 351 can be flexibly selected according to actual conditions.

[0038] In this case, when the back cover 100 of the electronic device is supported on the reflective surface 800, the first supporting protrusion 351 can further support the entire electronic device, and the raised size of the first side edge 410 in the electronic device is relatively larger, thereby making the distance between the sound hole 301 and the reflective surface 800 relatively large, which can further reduce the influence of the reflected sound waves generated by the sound waves transmitted from the sound hole 301 between the camera module 300 and the reflective surface 800 on the sound quality of the first speaker 210.

[0039] In addition, when the sound hole 301 is formed between the packaging cover 330 and the inner wall of the ring body 310 in the camera module 300, if the packaging cover 330 is in contact with a certain plane, the sound hole 301 will be blocked, thereby seriously affecting the normal operation of the first speaker 210. To this end, in the embodiment of the present application, the electronic device may further include a second supporting ridge 352, the second supporting ridge 352 is fixedly connected to the side of the ring body 310 in the camera module 300 away from the back cover 100, and the second supporting ridge 352 is arranged close to the first side 410. In the case of adopting the technical solution of the present application, the second supporting ridge 352 can be used to block the sound hole 301 to prevent the first speaker 210 from being hindered from sounding through the sound hole 301 due to the surface of the side of the camera module 300 away from the back cover forming a contact relationship with other planes.

[0040] Similarly, the second supporting flange 352 may also be adjacent to or located at the upper edge of the ring body 310 (i.e., the edge of the ring body 310 close to the first side edge 410), so that the second supporting flange 352 can provide a better barrier effect for the sound outlet. Specifically, the first supporting flange 351 and the second supporting flange 352 may both be arc-shaped structural members extending along the circumference of the ring body 310, and both may be fixed to the ring body 310 by bonding or the like. Alternatively, the ring body 310, the first supporting flange 351 and the second supporting flange 352 may be formed in an integrated manner, and the first supporting flange 351 is located on the side of the ring body 310 close to the second side edge 420, and the second supporting flange 352 is located on the side of the ring body 310 close to the first side edge 410.

[0041] As described above, both the first support protrusion 351 and the second support protrusion 352 can be arc-shaped structural parts. It should be noted that, in this case, on the circumference of the ring body 310, the sum of the angles spanned by the first support protrusion 351 and the second support protrusion 352 needs to be less than 360°, that is, the combined structure formed by the first support protrusion 351 and the second support protrusion 352 cannot be a closed ring structure. In this case, the side surfaces of the first support protrusion 351 and the second support protrusion 352 facing away from the rear cover 100 can both be planar structures. In other words, in the application embodiment, along the circumference of the ring body 310, the first supporting flange 351 and the second supporting flange 352 are spaced apart from each other so that a gap can be formed therebetween, thereby ensuring that when the first supporting flange 351 and the second supporting flange 352 are supported on a plane or in contact with the plane, the sound waves transmitted through the sound outlet 301 can be transmitted to the outside of the first supporting flange 351 and the second supporting flange 352 through the gap between the first supporting flange 351 and the second supporting flange 352.

[0042] In order to allow the sound waves on the inner side of the first support protrusion 351 and the second support protrusion 352 to be transmitted to the outer side of the first support protrusion 351 and the second support protrusion 352, in another embodiment of the present application, the surface of at least one of the first support protrusion 351 and the second support protrusion 352 facing away from the rear cover 100 may be a non-planar structure. In the embodiment of the present application, by making the surface of the first support protrusion 351 and / or the second support protrusion 352 facing away from the rear cover 100 uneven, the sound waves on the inner side of the first support protrusion 351 and the second support protrusion 352 may be transmitted to the outer side of the first support protrusion 351 and the second support protrusion 352 when the first support protrusion 351 and the second support protrusion 352 are supported on a plane or attached to a plane. In this case, in the circumferential direction of the ring body 310 , the sum of the angles spanned by the first support protrusion 351 and the second support protrusion 352 may be equal to 360°, that is, the first support protrusion 351 and the second support protrusion 352 may form a closed ring structure.

[0043] When the back cover 100 of the electronic device is supported on the reflecting surface 800, in order to further reduce the adverse effects of reflected sound waves generated between the reflecting surface 800 and the camera module 300 due to the sound waves transmitted from the sound outlet 301 on the sound quality of the electronic device, optionally, in the electronic device disclosed in the embodiment of the present application, the back cover 100 may be provided with a sound absorbing channel and a sound absorbing hole 103, and the sound absorbing channel is connected to the outside of the back cover 100 through the sound absorbing hole 103, so that when the sound waves are transmitted to the outside of the electronic device through the sound outlet 301 and reflected on the reflecting surface 800, the reflected sound waves generated can enter the sound absorbing channel through the sound absorbing hole 103 when propagating in a direction close to the back cover 100, thereby achieving the purpose of using the sound absorbing channel to absorb the aforementioned reflected sound waves, thereby preventing the reflected sound waves from propagating to the user's ears and interfering with the sound quality of the electronic device.

[0044] In detail, in order to ensure that the sound absorption channel has the ability to absorb reflected sound waves, the sound absorption channel can be designed using the sound elimination principle of a 1 / 4 wavelength tube, that is, when the length of the tube is one quarter of the wavelength corresponding to a sound wave of a certain frequency, the tube can eliminate noise from the sound wave of this frequency and reduce its sound wave energy. To this end, in the embodiment of the present application, the length of the sound absorption channel is one quarter of the audible wavelength range.

[0045] Among them, the range of audible wavelength is 1.7cm~17m. Of course, since the size of mobile phone electronic devices is usually around tens of centimeters, in the embodiment of the present application, the size of the sound absorption channel can be designed accordingly according to the specific size of the back cover 100 of the electronic device.

[0046] Taking into account that the low-frequency part of the reflected sound wave has a relatively weak influence on the sound quality, in a specific embodiment of the present application, the sound absorption channel can be mainly used to absorb sound waves with a frequency of 3000-8000 Hz. In this case, considering the speed of sound as 340 m / s, the wavelength range of the sound wave to be filtered is 42.5 mm-113.3 mm. Therefore, in the embodiment of the present application, the length of the sound absorption channel can be between 10.62 mm and 28.3 mm.

[0047] Optionally, the number of the sound absorption channel and the sound absorption hole 103 are both one. In order to further improve the filtering effect of the reflected sound waves, in a specific embodiment of the present application, the number of the sound absorption channel and the sound absorption hole 103 can be multiple, and they are connected one by one. Optionally, the lengths of the multiple sound absorption channels can be the same, so as to filter the part of a specific frequency in the reflected sound waves in a targeted manner to achieve the purpose of enhanced filtering. In another embodiment of the present application, in order to improve the overall filtering effect of the reflected sound waves, the lengths of the multiple sound absorption channels can be different. Of course, the lengths of the multiple sound absorption channels can be between 10.62 mm and 28.3 mm.

[0048] In addition, in the process of arranging multiple sound absorbing channels, multiple sound absorbing channels can be arranged along the aforementioned length direction, or multiple sound absorbing channels can be arranged along the width direction perpendicular to the back cover 100, wherein the width direction is perpendicular to both the aforementioned length direction and the thickness direction of the back cover 100. In another embodiment of the present application, the sound absorbing channels can be formed by drilling or the like, and multiple sound absorbing channels can be arranged relatively dispersedly around the first through hole 101 in the back cover 100, so that the absorption effect and comprehensiveness of the multiple sound absorbing channels on the reflected sound waves are relatively better, further improving the sound quality of the electronic device.

[0049] In another embodiment of the present application, the back cover 100 may include a cover body 110 and a cover plate 120. The cover body 110 and the cover plate 120 are formed separately. Both of them may be plate-shaped or sheet-shaped structural members. After both are processed, the cover plate 120 may be attached to and fixed to the cover body 110 as a whole by welding or bonding. In this case, the cover body 110 may be provided with a long groove 102, and the cover plate 120 may be provided with a sound-absorbing hole 103. After the cover body 110 and the cover plate 120 are processed, the cover plate 120 may be attached to the cover body 110 so that the cover plate 120 and the long groove 102 may enclose a sound-absorbing channel. Accordingly, the formed sound-absorbing channel is connected to the sound-absorbing hole 103 on the cover plate 120, which can greatly reduce the processing difficulty of the sound-absorbing channel.

[0050] In order to further improve the overall sound effect of the electronic device, in a specific embodiment of the present application, the electronic device may include a second speaker 220, and even a third speaker, and the second speaker 220 and the third speaker may output sound in other ways besides the back side. For example, the second speaker 220 may output sound from the front side, that is, the sound waves emitted by the second speaker 220 may propagate in the direction of the front side of the electronic device, and the third speaker may output sound from the top side or the bottom side, etc.

[0051] In detail, the electronic device may also include a frame 600, a display screen 700 and a second speaker 220, wherein the display screen 700 and the back cover 100 are respectively installed on opposite sides of the frame 600, and the three can serve as the external structure of the electronic device, and the side where the display screen 700 is located can generally be considered as the front of the electronic device, and correspondingly, the side where the back cover 100 is located can generally be considered as the back of the electronic device. In this case, by providing a third through hole 701 between the display screen 700 and the frame 600, the third through hole 701 is arranged opposite to the first through hole 101, the second speaker 220 is installed between the display screen 700 and the back cover 100, and the second speaker 220 is connected to the third through hole 701, so that the sound waves emitted by the second speaker 220 can be transmitted to the outside of the electronic device through the third through hole 701, thereby achieving the purpose of front sound output.

[0052] Based on the above technical solution, in order to further reduce the interference degree of the reflected sound wave S2 on the sound quality of the electronic device when the back cover 100 of the electronic device is supported on the reflective surface 800, as shown in FIG. Fig.11 As shown, in the embodiment of the present application, the second speaker 220 can be used to emit a coupled sound wave S3 when the second side 420 and the camera module 300 are supported on the reflective surface 800, wherein the coupled sound wave S3 is an anti-phase sound wave of the reflected sound wave S2, and the original sound wave S1 emitted by the first speaker 210 is reflected on the reflective surface 800 to form the aforementioned reflected sound wave S2. That is, in the embodiment of the present application, the principle of anti-phase sound waves can also be used to actively eliminate the reflected sound wave S2, thereby fundamentally reducing or even preventing the reflected sound wave S2 from being received by the user, thereby retaining only the original sound wave S1 emitted by the first speaker 210, and improving the quality of the sound heard by the user.

[0053] Specifically, the actual parameters of the reflected sound wave S2 generated by the sound wave emitted through the sound hole 301 and reflected on the reflecting surface 800 can be determined based on the specific position of the sound hole 301 on the camera module 300, as well as actual parameters such as the protruding size of the camera module 300 and its specific position on the back cover 100, so as to correspondingly determine the specific parameters of the coupled sound wave S3 that the second speaker 220 needs to emit in the above scenario.

[0054] In addition, in order to ensure that the second speaker 220 can work synchronously in the above-mentioned scenario, a posture sensor may also be provided in the electronic device disclosed in the embodiment of the present application. The posture sensor can be used to determine the current posture of the electronic device. When the posture sensor detects that the tilt angle of the electronic device meets the tilt angle range of the electronic device in the above-mentioned scenario and the first speaker 210 is in working state, the second speaker 220 can be controlled to emit the above-mentioned coupled sound wave S3.

[0055] In order to further improve the noise reduction accuracy of the second speaker 220 for the reflected sound wave S2, the electronic device may further include a proximity sensor, which may be installed on the side of the electronic device where the display screen 700 is located, to detect whether there is an obstruction on the side where the display screen 700 is located. In this case, when the posture sensor detects that the tilt angle of the electronic device meets the tilt angle range of the electronic device in the above scenario (such as 1°~5°), the proximity sensor does not detect an obstruction, and the first speaker 210 is in working state, the second speaker 220 may be controlled to emit the above-mentioned coupled sound wave S3.

[0056] Moreover, while the second speaker 220 continues to emit the above-mentioned coupled sound wave S3, the posture sensor and the proximity sensor can continue to work. Once the detection parameters of the posture sensor and the proximity sensor no longer meet the above-mentioned conditions, it is considered that the posture or position of the electronic device has changed. In this case, it is considered that the reflected sound wave S2 is no longer generated or has a relatively weak impact on the sound quality. For this reason, the second speaker 220 can be controlled to stop emitting the above-mentioned coupled sound wave S3.
