Description

Electronic device

[0001] The present application claims priority from the Chinese patent application No. 202411255518.X filed on September 9, 2024, and entitled "Electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of electronic technology, in particular to an electronic device. BACKGROUND

[0003] When the mobile phone is used in hand, the head of the mobile phone is probably in the upward and unobstructed state, so that the head of the mobile phone becomes the golden area of the antenna. The head of the mobile phone is also provided with a camera and a sound emitting element (such as a receiver). When the size of the camera and the sound emitting element is large, the camera and the sound emitting element will interfere with the feeding position of the antenna. When the sound emitting element is moved downward to avoid the feeding position of the antenna, the sound emitting channel between the sound emitting element and the sound outlet hole of the mobile phone will increase, which will affect the sound emitting effect of the sound emitting element. SUMMARY

[0004] The present application provides an electronic device to solve the technical problem that the size of the camera and the sound emitting element in the existing electronic device will interfere with the feeding position of the antenna.

[0005] The technical solution is as follows:

[0006] The present application provides an electronic device, comprising:

[0007] The metal frame comprises a first side frame provided with a slit;

[0008] The sound emitting element has an upper side edge on one side close to the first side frame. The upper side edge comprises a first area surface and a second area surface. The first area surface and the second area surface are distributed along the length direction of the upper side edge. The distance between the second area surface and the first side frame is smaller than the distance between the first area surface and the first side frame, so that an avoiding position for avoiding the feeding position of the antenna is formed between the first area surface and the first side frame.

[0009] The present application forms an avoiding position for avoiding the feeding position of the antenna between the first area surface and the first side frame. Since the distance between the second area surface and the first side frame is smaller than the distance between the first area surface and the first side frame, the upper side edge of the sound emitting element is as close to the first side frame as possible, so as to reduce the increase of the sound emitting channel length as much as possible, and further reduce the influence on the sound emitting effect of the sound emitting element.

[0010] In some implementations, the central axis of the sound emitting element perpendicular to the upper side edge is a reference axis, and the included angle between the reference axis and the first side frame is less than 90°.

[0011] In the present implementation, the angle between the reference axis L on the sound generating element and the first side frame is less than 90°, that is, the sound generating element is arranged in a rotating manner to avoid the antenna feed point, which is simple and easy to implement.

[0012] In some implementations, an avoiding notch is arranged at the position of the sound generating element close to the antenna feed point, and the surface of the avoiding notch facing the slot surface of the first side frame is the first area surface.

[0013] In the present implementation, the sound generating element is arranged in an inclined manner, and an avoiding notch is arranged at the position of the sound generating element close to the antenna feed point, so that the sound generating element can be inclined at a smaller angle relative to the first side frame while avoiding the antenna feed point, and the influence on the sound generating of the sound generating element can be minimized.

[0014] In some implementations, the upper side edge is inwardly recessed to form the avoiding notch, or the edge end of the sound generating element close to the antenna feed point is inwardly recessed to form the avoiding notch.

[0015] In the present implementation, compared with the sound generating element in which the upper side edge is inwardly recessed to form the avoiding notch and the sound generating element in which the edge end close to the antenna feed point is inwardly recessed to form the avoiding notch, the former has a relatively small change in the shape of the sound generating element, and the latter can reduce the angle of the sound generating element.

[0016] In some implementations, the angle between the reference axis and the first side frame ranges from 50° to 80°.

[0017] In the present implementation, the angle between the reference axis L and the second side frame is limited to 50° to 80°, that is, the sound generating element avoids the antenna feed point while having a relatively small influence on the sound generating of the sound generating element.

[0018] In some implementations, the central axis of the sound generating element perpendicular to the upper side edge is the reference axis, and the reference axis is perpendicular to the first side frame; an avoiding gap is formed at the position of the sound generating element close to the antenna feed point, and the surface of the avoiding gap facing the first side frame is the first area surface.

[0019] In the present implementation, the avoiding gap is formed at the position of the sound generating element close to the antenna feed point, so that the first area surface and the first side frame form an avoiding position while not increasing the length of the sound generating channel of the sound generating element.

[0020] In some implementations, the sound generating element includes a sound generating shell, a first inner core, and a second inner core, the shell is sequentially divided into a first shell part and a second shell part along a direction parallel to the upper side edge, the first area surface and the second area surface are formed on the first shell part and the second shell part respectively, the first inner core is connected to the first shell part, and the second inner core is connected to the second shell part.

[0021] In the present implementation, when the sound production element includes two cores, the positions of the first core and the second core are reasonably set in combination with the structural features of the outer contour of the sound production element, that is, the sound production element is formed with a relief gap at the position close to the antenna feed point. Meanwhile, when the sound production element includes two sound production cores, the two sound production cores can perform more fine processing and response to audio signals of different frequencies.

[0022] In some implementations, the electronic device further includes a circuit board and a connecting piece, the circuit board includes a main body part and an extension part, the extension part is connected with the main body part, the extension part extends into the relief position, and the connecting piece connects the first side frame and the extension part to form the antenna feed point.

[0023] In some implementations, the electronic device includes a frame and a support plate, the frame is arranged along the circumferential direction of the support plate, the frame includes a metal frame, and the support plate is provided with a limiting groove for limiting the sound production element.

[0024] In the present implementation, the sound production element can be conveniently positioned on the support plate by arranging the limiting groove on the support plate.

[0025] In some implementations, the inner side surface of the frame is formed with a relief surface for avoiding the second area surface, and the relief surface is recessed in the direction from the inner side surface of the frame to the outer side surface of the frame.

[0026] In the present implementation, by forming the relief surface on the inner side surface of the frame, the sound production element can be made to be as close as possible to the sound hole, so as to facilitate the reduction of the length of the sound outlet channel.

[0027] In some implementations, the frame includes an insulating frame, the insulating frame is arranged on the inner side surface of the metal frame, and the relief surface is formed on the insulating frame.

[0028] In some implementations, the first side frame is provided with a sound outlet, and the second area surface is close to the sound outlet relative to the first area surface. BRIEF DESCRIPTION OF DRAWINGS

[0055] Before explaining the electronic device provided by the embodiments of the present application in detail, the prior art and the scene are explained.

[0056] An antenna is a device used to transmit or receive radio waves. The antenna can transmit signals, effectively convert high-frequency current or guided wave energy in the transmission line into spatial electromagnetic waves, and radiate to the intended direction. The antenna can receive signals, effectively receive electromagnetic waves from a specific direction and convert them into high-frequency current or guided wave energy to deliver to the receiving device.

[0057] With the rapid development of the field of wireless communication technology, electronic devices such as mobile phones, tablet computers, and personal palm computers usually have cellular, wireless local area networks (WLAN), Bluetooth, and global positioning system (GPS) and other wireless communication functions. In realizing the above wireless communication functions, the antenna is an essential and important component. The antenna is arranged in the shell of the electronic device or arranged on the metal frame of the electronic device. The following describes the antenna arranged on the metal frame of the electronic device as a mobile phone.

[0058] Metal frame design of electronic equipment is more and more favored by people, in order to ensure the normal communication of the electronic equipment with metal frame design, at present, the metal frame is cut on the metal frame of the electronic equipment, and the cut metal frame is used as an antenna radiator to perform effective radiation.

[0059] Referring to FIGS. 1-2, FIG. 1(a) is a front view of a mobile phone in the prior art; FIG. 1(b) is a back view of the mobile phone in the prior art; and FIG. 2 is a schematic diagram of a first antenna unit formed by cutting a first side frame 31 of a metal frame 3 in the prior art.

[0060] Referring to FIG. 1, the electronic device 100 includes a display screen 1 and a housing, in one scenario, the housing includes a middle frame and a battery back cover 2, the display screen 1 and the battery back cover 2 are arranged on two sides of the middle frame, the display screen 1, the middle frame and the battery back cover 2 are arranged in sequence along the thickness direction of the mobile phone, and the display screen 1, the middle frame and the battery back cover 2 form a containing space, in which a mainboard, a mainboard support, a battery, a camera 6 and a speaker are arranged. The middle frame includes a metal frame 3, referring to FIG. 1, the metal frame 3 arranged along the circumferential direction of the mobile phone is shown.

[0061] When the mobile phone is used by hand, the head of the mobile phone is most likely in an upward and unobstructed state, so that the head of the mobile phone becomes a golden area of the antenna. Regarding the head of the mobile phone, referring to FIG. 1, the head of the mobile phone is roughly shown by a dashed box in FIG. 1(a) and FIG. 1(b). Since the head of the mobile phone becomes the golden area of the antenna, a cut is usually arranged on the metal frame 3 at the top of the mobile phone, so that the cut metal frame serves as an antenna radiator.

[0062] Referring to FIG. 1, the metal frame 3 includes a first side frame 31, a second side frame 32, a third side frame 33 and a fourth side frame 34, the first side frame 31 is arranged opposite to the third side frame 33, and the third side frame 33 is arranged opposite to the fourth side frame 34, wherein the first side frame 31 is the top frame of the mobile phone, and the third side frame 33 is the bottom frame of the mobile phone. Referring to FIG. 2, a cut 311 on the first side frame 31 is shown, and the cut 311 is filled with an insulating material, such as plastic, rubber, glass, wood, ceramic, etc., but not limited thereto.

[0063] The mobile phone includes a first antenna unit, and the first antenna unit includes a first radiation branch, a first feed-in part 4 and a first grounding point 5. Referring to FIG. 2, the second side frame 32 connected with the first side frame 31 is shown, the first grounding point 5 is arranged at one end of the second side frame 32 close to the first side frame 31, and the metal frame 3 between the cut 311 and the first grounding point 5 forms the first radiation branch.

[0064] The first radiating branch is electrically connected with the radio frequency source through the first feeding portion 4. The radio frequency source can be integrated on the circuit board 8 in the electronic device 100, and the first feeding portion 4 is connected with the circuit board 8. The position where the first feeding portion 4 is connected with the circuit board 8 is the antenna feeding point 9. The signal generated by the radio frequency source can be transmitted to the first radiating branch through the antenna feeding point, and then transmitted to the outside world by the first radiating branch. The signal received by the first radiating branch from the outside world is transmitted to the antenna feeding point 9, and then transmitted to the radio frequency source by the antenna feeding point 9.

[0065] The radio frequency source includes a transmitting path and a receiving path. The transmitting path includes power amplifiers, filters and other devices. The signal is processed by the power amplifiers, filters and other devices to amplify the power and filter, and then transmitted to the first radiating branch, and then transmitted to the outside world through the first radiating branch. The receiving path includes low-noise amplifiers, filters and other devices. The signal received by the first radiating branch from the outside world is processed by the low-noise amplifiers, filters and other devices to amplify the noise and filter, and then transmitted to the radio frequency chip.

[0066] In addition, please refer to FIG. 2, which shows the tuning connection portion 10. The tuning connection portion 10 connects the circuit board 8 and the first side frame 31, and is used to connect with the tuning circuit on the circuit board 8.

[0067] The first feeding portion 4 is relatively close to the slit 311, which facilitates the first antenna unit to better interact with the external space, and the efficiency of receiving and transmitting signals is higher. The first antenna unit is described above. By opening a plurality of slits in the metal frame 3 of the mobile phone, a plurality of antenna units can be formed. Different antennas can receive different frequency bands to realize various wireless communication functions of the mobile phone. Other antenna units are not specifically described herein.

[0068] Please refer to FIG. 3 and FIG. 4. FIG. 3 is a schematic diagram of the position relationship between the sound emitting element 7 with a small size and the antenna feeding point 9 in the prior art; and FIG. 4 is a schematic diagram of the position relationship between the sound emitting element 7 with a large size and the antenna feeding point 9 in the prior art.

[0069] The camera 6 and the sound emitting element 7 are arranged along a direction parallel to the first side frame 31.

[0070] The sound emitting element 7 is a receiver or a loudspeaker. The receiver is an element that converts electrical signals into sound signals. The working principle of the receiver is based on electromagnetic induction and loudspeaker principle. When an electrical signal passes through the coil in the receiver, a magnetic field is generated. This magnetic field interacts with the permanent magnet in the receiver, causing the coil to vibrate. The vibration of the coil is transmitted through the diaphragm connected to it, and the vibration of the diaphragm causes the surrounding air to vibrate, thereby producing sound.

[0071] When the sound generating element 7 is a receiver, the user can hold the phone and put the phone close to the ear when the user uses the phone to make a call, and the user can hear the sound through the sound outlet narrow slit in the middle of the top of the phone. When the sound generating element 7 is a loudspeaker, the loudspeaker outputs sound in two modes, one is a receiver mode with small volume, and the other is an external mode with large volume. In the receiver mode, the sound generating element 7 generates sound with small volume by reducing the power of the loudspeaker, and at this time, the user can hold the phone and put the phone close to the ear, and the user can hear the sound through the sound outlet narrow slit. In the external mode, the sound generating element 7 generates sound with large volume by increasing the power of the loudspeaker, and the user can hear the sound through the sound outlet hole 312 on the top of the phone. Please refer to FIG. 3 and FIG. 4, which show the sound outlet hole 312 arranged on the first side frame 31. The following mainly takes the sound generating element 7 as a loudspeaker as an example to explain the positional relationship between the sound generating element 7 and the antenna feed point 9.

[0072] Please refer to FIG. 3, when the size of the sound generating element 7 is relatively small, the antenna feed point 9 is arranged on the side of the sound generating element 7 away from the camera 6. When the size of the sound generating element 7 is relatively large, in order to avoid interference with the antenna feed point 9, the following scheme is currently adopted, that is, the sound generating element 7 is moved downward to avoid the antenna feed point 9. Please refer to FIG. 4, it can be seen that the antenna feed point 9 is arranged above the sound generating element 7, that is, the circuit board 8 is extended to form a connecting plate 81, the connecting plate 81 is arranged above the sound generating element 7 and connected with the first feed-in part 4 (not shown in FIG. 4) to form the antenna feed point 9.

[0073] Although moving the sound generating element 7 downward can avoid the antenna feed point 9, it will affect the sound generating effect of the sound generating element 7, the specific reasons are as follows: there is a sound generating channel between the sound generating element 7 and the sound outlet hole 312 on the top of the phone, when the sound generating element 7 vibrates, it pushes the surrounding air molecules to produce fluctuations to form sound waves, at the same time, the fluctuations of the air molecules will also drive the surrounding air flow, the airflow generated by the sound generating element 7 flows through the sound generating channel to the sound outlet hole 312, and then flows out through the sound outlet hole 312, and then the sound wave is transmitted to the surrounding environment. When the sound generating element 7 is moved downward, it is moved away from the sound outlet hole 312, which increases the length of the sound generating channel, so that the sound needs to pass through a relatively longer path during the transmission process, which will cause the airflow resistance to increase, and the airflow resistance will consume part of the energy, which will reduce the output efficiency of the loudspeaker, as a result, the loudspeaker needs a larger power input to achieve the same volume level, or the volume will decrease under the same power. In addition, the longer sound generating channel will cause different degrees of attenuation to different frequencies of sound, thereby causing energy loss.

[0074] Please refer to FIG. 4, the antenna feed point 9 is arranged above the sound production element 7, the sound production element 7 is parallel to the first side frame 31 near the edge of the first side frame 31, FIG. 4 shows the downward moving amount d of the sound production element 7 moving downward, since the sound production element 7 moves downward as a whole in the direction away from the sound hole 312, the length of the sound production channel is increased.

[0075] Based on the above problems, the electronic device provided in the present application is configured as follows: the sound production element has an upper side edge near one side of the first side frame, the upper side edge includes a first area surface and a second area surface, a clearance is formed between the first area surface and the first side frame, the antenna feed point is arranged in the clearance, and the distance between the second area surface and the first side frame is smaller than the distance between the first area surface and the first side frame. By configuring the shape and / or position of the sound production element, the clearance is formed between the first area surface and the first side frame, at the same time, the upper side edge of the sound production element is as close as possible to the first side frame, so as to reduce the increase of the length of the sound production channel as much as possible, thereby reducing the influence on the sound production of the sound production element.

In an example, the slits 311 can also be arranged on part of the second side frame 32, the third side frame 33 and the fourth side frame 34, or the slits 311 can be arranged on the first side frame 31, the second side frame 32, the third side frame 33 and the fourth side frame 34.

[0087] Please refer to FIG. 6, the position relationship between the sound emitting element 7 and the antenna feed point 9 is shown. The side of the sound emitting element 7 close to the first side frame 31 is the upper side edge 71, the upper side edge 71 includes a first area surface 711 and a second area surface 712, the first area surface 711 and the second area surface 712 are distributed along the length direction of the upper side edge 71. Please refer to FIG. 6, the first area surface 711 is close to the second side frame 32 relative to the second area surface 712, the distance between the second area surface 712 and the first side frame 31 is less than the distance between the first area surface 711 and the first side frame 31, and the avoiding position is formed between the first area surface 711 and the first side frame 31, and the antenna feed point 9 is located in the avoiding position.

[0088] In the embodiment, the distance between the second area surface 712 and the first side frame 31 is less than the distance between the first area surface 711 and the first side frame 31, so that the avoiding position is formed between the first area surface 711 and the first side frame 31, and the sound emitting element 7 is close to the first side frame 31 as much as possible, so as to reduce the length of the sound emitting channel 10 between the sound emitting element 7 and the sound hole 312 on the first side frame 31 as much as possible.

Specifically, for example, when the first area surface 711 and the second area surface 712 are both parallel to the first side frame 31, at this time, the first area surface 711 and the second area surface 712 are both planes, the distance from the first area surface 711 and the second area surface 712 to the first side frame 31 is a constant value, and the distance from the second area surface 712 to the first side frame 31 is less than the distance from the first area surface 711 to the first side frame 31; or, for example, when the first area surface 711 is parallel to the first side frame 31 and the second area surface 712 is not parallel to the first side frame 31, the distance from the second area surface 712 to the first side frame 31 is not a constant value, at this time, the maximum distance from the second area surface 712 to the first side frame 31 is less than the distance value from the first area surface to the first side frame 31; or, for example, when the first area surface 711 and the second area surface 712 are both not parallel to the first side frame 31, i.e. the distance between the first area surface 711 and the first side frame 31 is not a constant value, and the distance between the second area surface 712 and the first side frame 31 is also not a constant value, at this time, the maximum distance from the second area surface 712 to the first side frame 31 is less than the minimum distance from the first area surface 711 to the first side frame 31; or, for example, when the first area surface 711 is not parallel to the first side frame 31 and the second area surface 712 is parallel to the first side frame 31, i.e. the distance between the first area surface 711 and the first side frame 31 is not a constant value, the distance from the second area surface 712 to the first side frame 31 is a constant value, and the distance value from the second area surface 712 to the first side frame 31 is less than the minimum distance from the first area surface 711 to the first side frame 31.

[0090] Regarding the sound emitting channel 10 between the sound emitting element 7 and the sound hole 312, please refer to FIG. 7. In one scenario, the sound emitting element 7 includes a sound emitting shell 72 and a sound emitting core 73, and the sound emitting shell 72 is used to support and fix the sound emitting core 73. The sound emitting shell 72 cooperates with the sound emitting core 73 to form a rear cavity 74 of the sound emitting element 7, and the space between the sound emitting core 73 and the display screen 1 of the electronic device 100 forms a front cavity 75 of the sound emitting element 7. Taking the side of the display screen 1 of the electronic device 100 as the front side and the side of the battery back cover 2 as the back side, FIG. 5 and FIG. 6 are schematic diagrams of the sound emitting element 7 from the back side of the electronic device 100, and FIG. 8 is a schematic diagram of the sound emitting element 7 from the front side of the electronic device 100. Please refer to FIG. 8, which illustrates the sound emitting channel 10 connecting the front cavity 75 of the sound emitting element 7 and the sound hole 312, and the frame of the electronic device 100 and the display screen 1 etc. form the sound emitting channel 10. Please refer to FIG. 9, which is a schematic diagram of the relative position of the sound emitting element 7 and the sound emitting channel 10 in the electronic device 100. Please refer to FIG. 8, the sound hole 312 is located on the side close to the second area surface 712 relative to the sound emitting element 7, and since the second area surface 712 is closer to the first side frame 31, compared with the prior art of moving the sound emitting element 7 downward as a whole, the present embodiment can minimize the length of the sound emitting channel 10 between the sound emitting element 7 and the sound hole 312 on the first side frame 31 while forming an avoiding position between the first area surface 711 and the first side frame 31.

[0091] In the present embodiment, it is preferred that the end of the second area surface 712 away from the first area surface 711 is close to the first side frame 31 or the end of the second area surface 712 away from the first area surface 711 is in contact with the first side frame 31, so that the sound emitting element 7 is as close to the first side frame 31 as possible, so as to minimize the length of the sound emitting channel 10 between the sound emitting element 7 and the sound hole 312 on the first side frame 31. Please refer to FIG. 6, the end of the second area surface 712 away from the first area surface 711 is the first edge end 713 of the sound emitting element 7, and the end of the first area surface 711 away from the second area surface 712 is the second edge end 714 of the sound emitting element 7, and it is preferred that the first edge end 713 is in contact with the inner side of the first side frame 31.

[0092] In the present embodiment, the shape and / or position of the sound emitting element 7 can be set so that an avoiding position is formed between the first area surface 711 and the first side frame 31, and the distance between the second area surface 712 and the first side frame 31 is less than the distance between the first area surface 711 and the first side frame 31.

[0093] Please refer to Fig. 6, the position relationship between the sound production element 7 and the first slot 3111 is shown. Define one of the slots 311 on the first side frame 31 as the first slot 3111, please refer to Fig. 6, the first slot 3111 on the first side frame 31 is shown. When the antenna feed point 9 is arranged between the first area surface 711 of the sound production element 7 and the first side frame 31, usually the position of the first slot 3111 on the first side frame 31 is close to the sound production element 7, so as to facilitate the efficiency of receiving and transmitting signals to be higher.

[0094] In one scenario, the second side frame 32 is provided with a grounding point close to one end of the first side frame 31, and the section of the first side frame 31 and the second side frame 32 located between the first slot 3111 and the grounding point forms a first radiation branch of the antenna, the signal generated by the radio frequency source of the electronic device 100 can be transmitted to the first radiation branch through the antenna feed point 9, and transmitted to the outside by the first radiation branch; The signal received by the first radiation branch from the outside is transmitted to the antenna feed point 9 and further transmitted to the radio frequency source by the antenna feed point 9.

[0095] In this embodiment, the first area surface 711 and the first side frame 31 are provided with a clearance position to avoid the antenna feed point 9, and since the distance between the second area surface 712 and the first side frame 31 is less than the distance between the first area surface 711 and the first side frame 31, the upper side edge 71 of the sound production element 7 is as close to the first side frame 31 as possible, so as to minimize the increase of the sound production channel 10 length, and further reduce the influence on the sound production of the sound production element 7.

[0096] In one embodiment, the central axis of the sound production element 7 perpendicular to the upper side edge 71 is the reference axis L, and the angle between the reference axis L and the first side frame 31 is less than 90°.

[0097] Please refer to Fig. 6, the upper side edge 71 of the sound production element 7 and the reference axis L are shown, and the angle a between the reference axis L and the first side frame 31 is shown in Fig. 6, and the angle a between the reference axis L and the first side frame 31 is less than 90°.

[0098] In this embodiment, the reference axis L of the sound production element 7 is not perpendicular to the first side frame 31, and the position state of the sound production element 7 shown in Fig. 6 can be defined as an inclined state; The state that the reference axis L of the sound production element 7 is perpendicular to the first side frame 31 in the prior art is defined as a normal state.

[0099] The sound production element 7 in the normal state is converted to the sound production element 7 in the inclined state, which can be understood as rotating the sound production element 7 in the normal state clockwise along the direction indicated by the arrow A in FIG. 6 until the sound production element 7 is rotated to the position where the first side frame 31 and the first area surface 711 of the sound production element 7 form the avoiding position of the antenna feed point 9, at which time the sound production element 7 is in the inclined state as shown in FIG. 6. In a specific example, referring to FIG. 6, the center point O of the sound production element 7 is shown, and the sound production element 7 in the normal state is rotated clockwise along the direction indicated by the arrow A in FIG. 6, i.e., the center point O is taken as the rotation center.

[0100] In the embodiment, the area on the upper side edge 71 of the sound production element 7 directly opposite the antenna feed point 9 can be referred to as the first area surface 711, and the area on the upper side edge 71 other than the first area surface 711 and having a distance to the first side frame 31 smaller than the distance of the first area surface 711 to the first side frame 31 can be referred to as the second area surface 712.

[0101] Referring to FIG. 6, in the example of FIG. 6, the first area surface 711 and the second area surface 712 are both inclined surfaces, i.e., the distance between the first area surface 711 and the first side frame 31 is not a constant value, and the distance between the second area surface 712 and the first side frame 31 is also not a constant value, at which time the maximum distance between the second area surface 712 and the first side frame 31 is smaller than the minimum distance between the first area surface 711 and the first side frame 31.

[0102] In the embodiment, the angle between the reference axis L on the sound production element 7 and the first side frame 31 is less than 90°, i.e., the sound production element 7 is rotated to avoid the antenna feed point 9, which is a simple and easy-to-implement manner.

[0103] In the embodiment, it is preferred that the top corners of the sound production element 7 at least close to the antenna feed point 9 are round chamfers to avoid the antenna feed point 9 as much as possible. Referring to FIG. 6, the four top corners of the sound production element 7 are shown as round corners.

[0104] Referring to FIG. 10, (a) and (b) of FIG. 10 respectively show schematic diagrams of the sound production element 7 inclined at different angles relative to the first side frame 31.

[0105] In the embodiment based on the angle between the reference axis L on the sound production element 7 and the first side frame 31 being less than 90°, in one embodiment, the angle between the reference axis L and the first side frame 31 is 50°-80°.

[0106] Referring to FIG. 6, the angle a between the reference axis L and the first side frame 31 is shown. In the embodiment, the angle between the reference axis L and the first side frame 31 is 50°-80°, i.e., the range of the angle between the upper side edge 71 of the sound production element 7 and the first side frame 31 is 10°-40°.

[0107] Please refer to FIG. 10, the angle a between the reference axis L and the first side frame 31 in (a) of FIG. 10 is greater than the angle a between the reference axis L and the first side frame 31 in (b) of FIG. 10, the smaller the angle a between the reference axis L and the first side frame 31, the more inclined the sound production element 7, the farther the first area surface 711 from the first side frame 31, and the more space for the antenna feed point 9. Comparing (a) and (b) in FIG. 10, the more inclined the sound production element 7, the more the front cavity 75 of the sound production element 7 deviates from the direction of the sound hole 312, and the more the length of the sound production channel 10 between the sound production element 7 and the sound hole 312. Therefore, under the condition of meeting the antenna feed point 9, the inclination of the sound production element 7 should be minimized, that is, the angle a between the reference axis L and the first side frame 31 should be maximized.

[0108] In this embodiment, the angle between the reference axis L and the second side frame is limited to 50°-80°, that is, under the condition of avoiding the antenna feed point 9 by the sound production element 7, the sound production element 7 has less impact on the sound production.

[0109] Please refer to FIGS. 11-12, FIG. 11 is a partial structural schematic diagram of the frame of the electronic device 100 provided in the embodiments of the present application; and FIG. 12 is a partial enlarged view of A in FIG. 11.

[0110] In the embodiment based on the angle between the reference axis L on the sound production element 7 and the first side frame 31 being less than 90°, in one implementation, a limiting groove 121 is formed on the frame of the electronic device 10, and the sound production element 7 is in an inclined state when the sound production element 7 is arranged on the limiting groove 121.

[0111] In one example, the frame of the electronic device can be a middle frame, specifically, the frame includes a side frame and a support plate 12, the side frame is arranged along the circumferential direction of the support plate 12, and the side frame includes a metal side frame 3. Please refer to FIG. 11, the limiting groove 121 is shown to be arranged on the support plate 12, and the metal side frame 3 is shown to be arranged along the circumferential direction of the support plate 12. It is preferred that an avoiding surface 111 for avoiding the second area surface 712 of the sound production element 7 is formed on the inner side surface of the side frame, the avoiding surface 111 is recessed from the inner side surface of the side frame to the outer side surface of the side frame, so that the one end of the upper side edge 71 of the sound production element 7 far away from the antenna feed point 9 is as close to the top as possible, so as to minimize the length of the sound production channel 10 between the sound production element 7 and the sound hole 312 on the first side frame 31. Please refer to FIG. 12, the avoiding surface 111 on the inner side surface of the side frame is shown.

[0112] Regarding the frame, in one example, please refer to FIG. 11, the frame includes a metal frame 3 and an insulating frame 11, the insulating frame 11 is arranged on the inner side of the metal frame 3, when the inner side of the frame is formed with a relief surface 111, the relief surface 111 is formed on the insulating frame 11.

[0113] The first slit 3111 needs to be plugged with an insulating material, the structure for plugging the first slit 3111 is a plugging column, the material of the plugging column and the insulating frame 11 can be set to be the same, or the material of the plugging column and the insulating frame 11 can be set to be different. The material of the insulating frame 11 can be plastic or rubber, and the material of the plugging column can be plastic, rubber, glass, wood, ceramic, etc.

[0114] Preferably, the plugging column and the insulating frame 11 are integrally formed.

[0115] When the inner frame includes a metal frame 3 and an insulating frame 11, please refer to FIG. 12, a connecting hole 112 is arranged on the insulating frame 11, so that the first side frame 31 is connected to the circuit board 8 of the electronic device 100 through the connecting piece to form an antenna feed point 9.

[0116] Please refer to FIG. 11, a communication hole 122 is arranged on the groove bottom surface of the limiting groove 121, the communication hole 122 is arranged to form a front cavity 75 of the sound generating element 7 between the sound generating element 7 and the display screen 1 of the electronic device 100.

[0117] In this embodiment, the limiting groove 121 can limit the installation position of the sound generating element 7 on the frame, regarding the fixing method of the sound generating element 7 on the frame, a screw or other connecting piece can be used to detachably fix the sound generating element 7 on the frame. In one specific example, please refer to FIG. 12, two clamping pieces 123 are arranged on the support plate 12, the two clamping pieces 123 are arranged on the two sides of the limiting groove 121, and the two clamping pieces 123 are used to clamp and connect the sound generating element 7 on the support plate 12.

[0118] Please refer to FIGS. 13-16, FIG. 13 is a schematic view of the sound generating element 7 in an inclined state and the relief notch 76 arranged on the sound generating element 7 according to the embodiment of the present application; FIG. 14 is a partial enlarged view of B in FIG. 13; FIG. 15 is another schematic view of the sound generating element 7 in an inclined state and the relief notch 76 arranged on the sound generating element 7 according to the embodiment of the present application; and FIG. 16 is a partial enlarged view of C in FIG. 15.

[0119] In the embodiment where the angle between the reference axis L on the sound production element 7 and the first side frame 31 is less than 90°, in an embodiment, the sound production element 7 is provided with a notch 76 at the position close to the antenna feed point 9, the face of the notch 76 towards the first side frame 31 is the first area face 711, and the area on the upper side edge 71 of the sound production element 7 where the notch 76 is not provided is the second area face 712. Since the sound production element 7 is in an inclined state and the face of the notch 76 towards the first side frame 31 is the first area face 711, the distance from any point on the first area face 711 to the first side frame 31 is greater than the distance from any point on the second area face 712 to the first side frame 31.

[0120] Please refer to FIG. 13-FIG. 16, which show the notch 76 provided on the sound production element 7. When the notch 76 is provided on the sound production element 7, the angle between the upper side edge 71 of the sound production element 7 and the first side frame 31 can be reduced, i.e. the inclination angle of the sound production element 7 relative to the first side frame 31 can be reduced, while avoiding the antenna feed point 9, so as to reduce the impact on the sound production of the sound production element 7.

[0121] There are two cases regarding the notch 76 provided on the sound production element 7 at the position close to the antenna feed point 9 in the present embodiment:

[0122] (1) The upper side edge 71 of the sound production element 7 is inwardly recessed to form the notch 76.

[0123] Please refer to FIG. 13 and FIG. 14, which show that the first area face 711 and the second area face 712 of the upper side edge are not in the same plane. FIG. 13 shows the right side edge 77 of the sound production element 7. The upper side edge 71 of the sound production element 7 is inwardly recessed at the end close to the right side edge 77 to form the notch 76, so as to avoid the interference between the first area face 711 and the antenna feed point 9.

[0124] (2) The corner end of the sound production element 7 close to the antenna feed point 9 is inwardly recessed to form the notch 76.

[0125] Please refer to FIG. 15 and FIG. 16, which show the notch 76. The corner end of the sound production element 7 close to the antenna feed point 9 is inwardly recessed to form the notch 76, i.e. not only the upper side edge 71 of the sound production element 7 is inwardly recessed, but also the right side edge 77 of the sound production element 7 is inwardly recessed, to jointly form the notch 76. Please refer to FIG. 16, the upper side edge 71 of the sound production element 7 is inwardly recessed at the end close to the right side edge 77 to form the first area face 11 towards the first side frame 31.

[0126] Compared with the case that the upper side edge 71 of the sound production element 7 is inwardly recessed to form the avoiding notch 76 and the edge end of the sound production element 7 close to the antenna feed point 9 is inwardly recessed to form the avoiding notch 76, the former changes the shape of the sound production element 7 relatively less, and the latter can reduce the angle of the sound production element 7 tilting.

[0127] In the embodiment, the sound production element 7 is arranged to be inclined and the avoiding notch 76 is arranged at the position of the sound production element 7 close to the antenna feed point 9, so that the antenna feed point 9 is avoided and the angle of the sound production element 7 relative to the first side frame 31 is reduced, and the avoiding position of the antenna feed point 9 is formed between the first area 711 and the first side frame 31, while the influence on the sound production of the sound production element 7 is reduced as much as possible.

[0128] Please refer to FIG. 17 and FIG. 18, FIG. 17 is a schematic diagram of the avoiding notch 78 arranged on the sound production element 7 in the normal state of the sound production element 7, and FIG. 18 is a schematic diagram of the relative position between the sound production element 7 and the antenna feed point 9 when the sound production element 7 includes two cores.

[0129] In one embodiment, the central axis of the sound production element 7 perpendicular to the upper side edge 71 is the reference axis L, the reference axis L is arranged vertically relative to the first side frame 31, the avoiding notch 78 is formed at the position of the sound production element 7 close to the antenna feed point 9, and the surface of the avoiding notch 78 facing the first side frame 31 is the first area 711. The region of the sound production element 7 where the upper side edge 71 is not provided with the avoiding notch 78 is the second area 712. Since the surface of the avoiding notch 78 facing the first side frame 31 is the first area 711, the distance from any point on the first area 711 to the first side frame 31 is greater than the distance from any point on the second area 712 to the first side frame 31.

[0130] Please refer to FIG. 17, the reference axis L of the sound production element 7 is shown to be perpendicular to the first side frame 31. That is, in the embodiment, the sound production element 7 is not arranged to be inclined, but the shape of the sound production element 7 is changed, and the avoiding notch 78 is arranged at the position of the sound production element 7 close to the antenna feed point 9.

[0131] Regarding the avoiding notch 78 formed at the position of the sound production element 7 close to the antenna feed point 9, specifically, the edge end of the sound production element 7 close to the antenna feed point 9 is inwardly recessed to form the avoiding notch 78. Please refer to FIG. 17, the upper side edge 71 and the right side edge 77 of the sound production element 7 are shown. The edge end of the sound production element 7 close to the antenna feed point 9 is inwardly recessed to form the avoiding notch 78, that is, one end of the upper side edge 71 of the sound production element 7 close to the right side edge 77 is inwardly recessed, and one end of the right side edge 77 of the sound production element 7 close to the upper side edge 71 is also inwardly recessed, to jointly form the avoiding notch 78.

[0132] In the embodiment, the sound producing element 7 is formed with an avoiding gap 78 at the position close to the antenna feed point 9, so that the first area surface 711 is formed with an avoiding position between the first side frame 31, without increasing the length of the sound producing passage 10 of the sound producing element 7.

[0133] As to the shape of the avoiding gap 78, in a specific example, please refer to Fig. 17, the first area surface 711 and the second area surface 712 are parallel, and both the first area surface 711 and the second area surface 712 are parallel to the first side frame 31. Please refer to Fig. 17, the third area surface 715 of the sound producing element 7 is shown, the third area surface 715 connects the first area surface 711 and the second area surface 712, and the third area surface 715 is perpendicular to the first area surface 711 and the second area surface 712. Preferably, the third area surface 715 is connected to the first area surface 711 through a circular arc transition, and the third area surface 715 is connected to the second area surface 712 through a circular arc transition. Alternatively, in a specific example, the first area surface 711 is a circular arc surface, one end of the first area surface 711 is connected to the second area surface 712, and the other end of the first area surface 711 is connected to the right side edge 77 of the sound producing element 7.

[0134] As to the sound producing element 7, the sound producing element 7 generally includes a sound producing shell 72 and a sound producing core 73 connected to the sound producing shell 72, and the sound producing core 73 mainly includes a magnet, a voice coil, a diaphragm, and a centering spider, etc. The magnet can be a permanent magnet or an electromagnet, which functions to generate a stable magnetic field so that the voice coil can move in it to produce sound; the voice coil is located in the magnetic field of the magnet, when audio current passes through the voice coil, the voice coil will produce movement, the voice coil is made of wire wound on the framework, its movement drives the diaphragm to vibrate, thereby producing sound; the diaphragm, also known as the paper cone or the membrane, is the vibrating part of the loudspeaker, the diaphragm is connected to the voice coil, the movement of the voice coil drives the diaphragm to vibrate, thereby producing sound. The centering spider is used to fix the position of the voice coil, prevent the voice coil from shifting, and reduce the weight of the voice coil to improve the efficiency of the loudspeaker. The design and material selection of the centering spider have a key influence on the performance and sound quality of the loudspeaker.

[0135] The sound producing element 7 provided in the embodiment is formed with the avoiding gap 78 at the position close to the antenna feed point 9 by changing the shape of the sound producing shell 72, and at the same time, the position of the sound producing core 73 is adjusted appropriately according to the change of the shape of the sound producing shell 72 to adapt to the change of the shape of the sound producing shell 72.

[0136] In one embodiment, the sound producing element 7 includes one sound producing core 73; in another embodiment, the sound producing element 7 includes two sound producing cores 73.

[0137] When the sound production element 7 includes two sound production cores 73, the two sound production cores 73 can process and respond to audio signals of different frequencies more finely. For example, one sound production core 73 can be responsible for processing low-frequency signals exclusively, providing stronger bass effects; the other sound production core 73 is responsible for high-frequency signals, making the high pitch clearer and brighter, thereby improving the clarity, level and fidelity of the overall sound quality. In addition, even if one of the sound production cores 73 fails or performance declines, the other sound production core 73 can continue to work, to some extent ensuring the basic sound production function of the loudspeaker and improving the reliability and stability of the loudspeaker.

[0138] In the example based on the sound production element 7 including two sound production cores 73, in an embodiment, the sound production element 7 includes a sound production shell 72, a first core and a second core, the sound production shell 72 is sequentially divided into a first shell part 721 and a second shell part 722 along a direction parallel to the upper side edge 71, the first area surface 711 and the second area surface 712 are formed on the first shell part 721 and the second shell part 722 respectively, the first core is connected to the first shell part 721, and the second core is connected to the second shell part 722.

[0139] Please refer to FIG. 18, which shows the first shell part 721 and the second shell part 722. In FIG. 18, the sound production shell 72 is divided into two parts by auxiliary dotted lines, one part is the first shell part 721, and the other part is the second shell part 722. The first core is connected to the first shell part 721, and the second core is connected to the second shell part 722. According to the size relationship between the first shell part 721 and the second shell part 722, the size of the first core is smaller than the size of the second core. In this embodiment, in the case where the sound production element 7 includes two cores, in combination with the structural features of the outer contour of the sound production element 7, the position of the sound production element 7 close to the antenna feed point 9 is formed with a relief gap 78.

[0140] It should be noted that when the sound production element 7 includes one core, the size of the relief gap 78 only needs to meet the requirement of avoiding the antenna feed point 9; when the sound production element 7 includes two cores, and the sound production element 7 includes a first core and a second core along a direction parallel to the upper side edge 71, and the first core is connected to the first shell part 721 and the second core is connected to the second shell part 722, in one scenario, the size of the relief gap may be larger than the size of the antenna feed point 9 due to the smaller size of the second core. Please refer to FIG. 18, which shows that the size of the relief gap is larger than the size of the antenna feed point 9.

[0141] Please refer to FIG. 19, which is a schematic diagram of the circuit board 8 connected to the first side frame 31 through a connecting piece.

[0142] Regarding the antenna feed point 9, in one embodiment, the electronic device further comprises a circuit board 8 and a connecting member, the circuit board 8 comprises a main body part 82 and an extension part 83, the extension part 83 is connected with the main body part 82, the extension part 83 extends into the avoiding position, and the connecting member connects the first side frame 31 and the extension part 83 to form the antenna feed point 9.

[0143] Please refer to FIG. 19, which shows the extension part 83 of the circuit board 8. The radio frequency source is integrated on the circuit board 8, and the extension part 83 is connected with the first side frame 31 through the connecting member, so that the first radiation branch formed by the first side frame 31 and the second side frame 32 is connected with the radio frequency source.

[0144] In one example, when the extension part 83 can be placed in the avoiding position, the avoiding position between the first area surface 711 and the first side frame 31 can be formed to avoid the antenna feed point 9. Therefore, the size of the avoiding position space is sufficient to enable the extension part 83 to extend into the avoiding position.

[0145] Please refer to FIG. 19, the extension part 83 is located between the first side frame 31 and the first area surface 711. In order to form the avoiding position between the first area surface 711 and the first side frame 31 to avoid the antenna feed point 9, not only the distance between the second area surface 712 and the first side frame 31 is smaller than the distance between the first area surface 711 and the first side frame 31, but also the thickness of the first side frame 31 facing the first area surface 711 is reduced as much as possible to facilitate accommodating the extension part 83 between the first area surface 711 and the first side frame 31. Please refer back to FIG. 11 and FIG. 12, in the example that the frame of the electronic device comprises the frame and the support plate 12, and the frame comprises the metal frame 3 and the insulating frame 11, the thickness of the insulating frame 11 facing the first area surface 711 can be reduced to avoid the extension part 83.

[0147] In this embodiment, the second connecting part can be a spring, a screw, a spring sheet, a conductive cloth, conductive foam or conductive glue, etc., to realize the electrical connection between the first connecting part 13 and the extension part 83. For example, in one specific example, the second connecting part is a spring sheet, the first connecting part 13 is pressed on the extension part 83 through the spring sheet, and the spring sheet can be connected with the radio frequency source on the main body part 82 through a microstrip line.

[0148] In the example that the second connecting part is a spring sheet, the material of the second connecting part and the first connecting part 13 can be the same, and the second connecting part and the first connecting part 13 can be made of stainless steel or beryllium copper. The surface of the second connecting part and the first connecting part 13 can be plated with nickel and then plated with gold to ensure that the second connecting part and the first connecting part 13 have good electrical conductivity. In addition, plating gold on the surface of the second connecting part and the first connecting part 13 can prevent oxidation and prolong the service life of the second connecting part and the first connecting part 13.

[0149] In the embodiment, the first connecting part 13 can be welded or adhered to the first side frame 31 by conductive glue.

[0150] In a specific example, the first connecting part 13 is an L-shaped plate, the vertical surface of the first connecting part 13 is connected to the first side frame 31, and the horizontal surface of the first connecting part 13 is connected to the extension part 83.
