[0023] Furthermore, it is required that the present application be understood not only by the actual terms used but also by the meanings connoted by each term.

[0024] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0025] The present application embodiment provides an electronic device. Figures 1 to 7 , the electronic device 100 provided in the embodiment of the present application includes: a frame 110, a circuit board 120, a bracket 130, a speaker unit 140 and a camera decoration 150. For example, when the electronic device 100 is a mobile phone, the frame 110 is the middle frame of the mobile phone, the circuit board 120 is the main board or the sub-board, the bracket 130 can also be called the main board bracket, and the camera decoration 150 is a component provided outside the camera module of the electronic device 100. The speaker unit 140 is a component that converts electrical signals into sound.

[0026] The frame 110, the circuit board 120 and the bracket 130 are arranged in sequence. For example, when the electronic device 100 is a mobile phone, the frame 110 is a mobile phone middle frame, the circuit board 120 is a motherboard, and the bracket 130 is a motherboard bracket, the motherboard is arranged in the mobile phone middle frame, and the bracket 130 is arranged on a side of the motherboard away from the mobile phone middle frame, so that the mobile phone middle frame, the motherboard and the motherboard bracket are distributed in sequence.

[0027] Furthermore, the speaker unit 140 is disposed between the bracket 130 and the circuit board 120, and the sound outlet 141 of the speaker unit 140 is located on the side of the speaker unit 140 that is away from the circuit board 120. The speaker unit 140, the bracket 130 and the circuit board 120 enclose a first rear sound cavity 161, and the circuit board 120 and the frame 110 enclose a second rear sound cavity 162. The circuit board 120 is provided with a through hole 121, and the first rear sound cavity 161 and the second rear sound cavity 162 are connected through the through hole 121. The bracket 130 is provided with a sound channel 131, and the sound outlet 141 and the inner wall of the sound channel 131 enclose a front sound cavity 163, and the camera decoration 150 is provided with a sound outlet hole 151 connected to the front sound cavity 163. The sound emitted by the speaker unit 140 can be transmitted to the outside of the electronic device 100 through the front sound cavity 163 and the sound outlet hole 151.

[0028] In this way, in the embodiment of the present application, the speaker unit 140, the bracket 130 and the circuit board 120 enclose the first rear sound cavity 161, the circuit board 120 and the groove wall of the second groove 111 enclose the second rear sound cavity 162, and the first rear sound cavity 161 and the second rear sound cavity 162 are connected through the through hole 121 on the circuit board 120, so that the connected first rear sound cavity 161 and the second rear sound cavity 162 can constitute the rear sound cavity of the speaker unit 140. It can be further concluded that since the rear sound cavity is not enclosed by the shell of the electronic device 100 located on the outer surface, the electronic device 100 basically does not produce shell vibration phenomenon.

[0029] In addition, the inner wall of the sound channel 131 formed by the sound outlet 141 of the speaker unit 140 and the bracket 130 forms a front sound cavity 163, and the sound outlet 151 of the electronic device 100 is arranged on the camera decoration 150. In this way, the front sound cavity 163 is not surrounded by the shell of the electronic device 100 located on the outer surface. Therefore, the possibility of shell vibration of the electronic device 100 can be further reduced.

[0030] refer to Figure 2 and Figure 3 In some embodiments, the bracket 130 includes a first cover 132 and a second cover 133. The second cover 133 is disposed on a side of the first cover 132 facing the circuit board 120, and the second cover 133 and the first cover 132 form a sound channel 131.

[0031] It should be noted that in other embodiments, the bracket 130 may be an integrated structure. However, when the bracket 130 is an integrated structure, it is difficult to process the sound channel 131. Therefore, the difficulty of manufacturing the bracket 130 can be reduced by splicing the second cover 133 and the first cover 132 to form the sound channel 131.

[0032] refer to Figures 2 to 4 In some embodiments, the first cover 132 is provided with a first groove 1321, and the notch of the first groove 1321 faces the circuit board 120. The speaker unit 140 is arranged adjacent to the second cover 133, and the speaker unit 140 and the second cover 133 cover the notch of the first groove 1321. In this way, the notch of the first groove 1321 can be covered by the second cover 133 and the speaker unit 140 arranged side by side, so that the sound outlet 141 of the speaker unit 140, the second cover 133 and the groove wall of the first groove 1321 form a front sound cavity 163.

[0033] In some embodiments, the gap between the speaker unit 140 and the second cover 133 , the gap between the outer periphery of the speaker unit 140 and the groove wall of the first groove 1321 , and the gap between the second cover 133 and the groove wall of the first groove 1321 are all sealed by sealant.

[0034] For example, in combination Figure 4 , the second cover 133 can be first arranged on one side of the notch of the first groove 1321. Further, the speaker unit 140 can be arranged at a position adjacent to the second cover 133, so as to cover the notch of the first groove 1321 with the second cover 133 and the speaker unit 140 arranged side by side. Further, glue can be dispensed at the gap between the second cover 133 and the speaker unit 140 arranged side by side, and glue can be dispensed at the periphery of the second cover 133 and the speaker unit 140 arranged side by side, so as to seal the second cover 133, the speaker unit 140 and the groove wall of the first groove 1321, so as to improve the sealing performance of the front sound cavity 163.

[0035] refer to Figure 3 In some embodiments, the portion of the circuit board 120 opposite to the speaker unit 140 is provided with an electronic component 122. In this way, the component arrangement density of the board surface of the circuit board 120 can be increased by arranging the electronic component 122 at the portion of the circuit board 120 opposite to the speaker unit 140. For example, the electronic component 122 may include at least one of a resistor, an inductor, and a capacitor.

[0036] Combination Figure 3 and Figure 4In some embodiments, a flexible adhesive member 142 and a support member 143 are provided on the periphery of the speaker unit 140 on the side opposite to the sound outlet 141. The speaker unit 140 is connected to the circuit board 120 via the flexible adhesive member 142, and the thickness of the support member 143 is greater than the thickness of the electronic component 122. In this way, for example, when the electronic device 100 falls and collides with the ground, the support member 143 is supported between the speaker unit 140 and the circuit board 120, so as to prevent the speaker unit 140 from colliding with the electronic component 122.

[0037] For example, the flexible adhesive member 142 may be a breathable foam. Adhesives are respectively provided on two opposite sides of the foam along the thickness direction. Thus, one side of the foam is bonded to the side of the speaker unit 140 away from the sound outlet 141, and the other side is bonded to the circuit board 120. The support member 143 may be a polyethylene terephthalate (PET) support member.

[0038] refer to Figure 3 In some embodiments, the first cover body 132 includes a main body 1322 and a metal insert 1323 embedded in the main body 1322. The metal insert 1323 is opposite to the sound output portion 141 and is arranged at intervals. In this way, the metal insert 1323 can be arranged at a position of the first cover body 132 opposite to the sound output portion 141, so that the mechanical strength of the portion opposite to the sound output portion 141 of the first cover body 132 can meet the requirements while minimizing the thickness of the portion of the first cover body 132 opposite to the sound output portion 141. Exemplarily, the main body 1322 is a plastic part, and the metal insert 1323 is formed by stamping a steel sheet. The metal insert 1323 can be embedded in the main body 1322 by insert molding.

[0039] In some embodiments, a first dustproof net 134 is provided at one end of the sound channel 131 away from the sound outlet 141. The first dustproof net 134 is provided on the side of the second cover 133 away from the circuit board 120. A second dustproof net 135 is further provided between the first dustproof net 134 and the second cover 133, and the aperture of the mesh of the second dustproof net 135 is smaller than the aperture of the mesh of the first dustproof net 134. In this way, the dustproof performance of the electronic device 100 can be improved by providing the first dustproof net 134 and the second dustproof net 135.

[0040] refer to Figure 3 and Figure 4 In some embodiments, the first cover 132 is provided with a first annular protrusion 1324 protruding toward the circuit board. A first sealing rubber ring is provided between the first annular protrusion 1324 and the circuit board 120. Figure 3The frame 110 is provided with a second annular protruding portion 112 protruding toward the circuit board 120. A second sealing rubber ring is provided between the second annular protruding portion 112 and the circuit board 120.

[0041] refer to Figure 3 In some embodiments, the frame 110 includes a main body 110a. The main body 110a is provided with a second groove 111. The circuit board 120 is sealed in the notch of the second groove 111, and the circuit board 120 and the groove wall of the second groove 111 form a second rear sound cavity 162. In this way, the difficulty of setting the second rear sound cavity 162 can be reduced.

[0042] For example, reference Figure 3 The main body 110a includes a protruding ring protruding toward the circuit board 120. In this way, the area of ​​the main body 110a where the protruding ring is arranged forms a second groove 111. The circuit board 120 covers the end of the protruding ring, thereby forming a second rear sound cavity 162 with the groove wall of the second groove 111.

[0043] refer to Figure 1 , illustratively, the frame 110 further includes a frame portion 110b. The frame portion 110b is used to connect with the back cover 170 of the electronic device 100. In addition, the side of the frame portion 110b away from the back cover 170 is also used to connect with the display module of the electronic device 100. In other words, the display module and the back cover 170 are respectively connected to the two sides of the frame portion 110b.

[0044] In addition, the frame portion 110b is disposed outside the main body portion 110a. The main body portion 110a is used to connect with the circuit board 120 and the battery of the electronic device 100. In other words, the main body portion 110a can serve as a mounting base for components such as the circuit board 120 and the battery.

[0045] In some embodiments, the frame 110 further includes a frame portion 110 b. The electronic device 100 further includes a back cover 170. The back cover 170 is connected to the frame portion 110 b. The camera decoration 150 is connected to the back cover 170, and the camera decoration 150 is disposed on a side of the bracket 130 away from the circuit board 120.

[0046] Exemplarily, the electronic device 100 further includes a battery, which is disposed between the back cover 170 and the frame 110. When the back cover 170 is used to cover the battery, the back cover 170 may also be referred to as a battery back cover. Further, the electronic device 100 further includes a rear camera, and the camera decoration 150 is disposed outside the rear camera.

[0047] In some embodiments, the camera decoration 150 is provided with a sound outlet 151 connected to the front sound cavity 163. In this way, the sound emitted by the speaker unit 140 can be transmitted to the outside of the electronic device 100 through the speaker unit 140 and the sound outlet 151.

[0048] In some embodiments, the camera decorative part 150 can be processed by injection molding. It should be noted that due to the special properties of plastic materials, it is easier to flow than metal, and plastic materials are easier to process into a shape with sharp corners and straight edges. For example, a high-precision mold (such as an electroforming mold) can be used for casting to process the camera decorative part 150.

[0049] In some embodiments, the camera decoration 150 adopts a multi-piece design. The appearance functional parts of the camera decoration 150 are made of sheet decorative patches. The sheet material can achieve a metal-like effect at a low cost, and the sharp corners and straight edges can be made by processing the sheet. The structure of the camera decoration 150 connecting the sheet decorative pieces inside can be formed by stamping steel sheets. Since the steel sheet support is not exposed on the outer surface of the electronic device 100, the appearance defects (such as large rounded corners, etc.) caused by the use of low-cost stamping technology can be ignored.

[0050] Specifically, refer to Figure 6 and Figure 7 , the main body of the camera decorative member 150 can be processed first. Further, the sound outlet decorative cover can be processed by a stamping process, and the sound outlet hole 151 is opened in the sound outlet decorative cover. Then, the sound outlet decorative cover can be connected to the main body of the camera decorative member 150.

[0051] Exemplarily, the electronic device 100 may be a mobile phone or a tablet computer, etc. Alternatively, the electronic device 100 may be a wearable device such as a smart watch or a head mounted display.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
