Description

Technical Field

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

[0002] At present, in order to enhance the antenna performance of electronic devices and improve the network-keeping capability and gaming performance of the low-frequency antenna LB, a printed circuit board (PCB) of an antenna assembly is often added to the speaker box (BOX). In the relevant structure, the electronic device includes a device housing, PCB, BOX, coaxial line, coaxial line seat, screws, shrapnel and BOX monomer. The PCB is pre-fixed on the device housing or BOX. After the BOX is installed on the device housing, screws are used to penetrate the mounting holes on the BOX and PCB in the thickness direction of the electronic device to fix the BOX and PCB together on the device housing. The coaxial line spans from the other end of the BOX and is connected to the coaxial line seat. The coaxial line seat is welded to the PCB to realize the transmission of antenna signals.

[0003] In the above solution, the PCB occupies more space in the BOX back cavity, resulting in a small volume of the BOX back cavity, which affects the sound effect of the speaker. If the size of the back cavity is increased, the thickness of the electronic device needs to be increased or the battery space needs to be squeezed, but this goes against the user's demand for lightness and long battery life.

[0004] Therefore, how to reduce the impact on the back cavity volume of the BOX and increase the back cavity volume of the speaker without affecting the antenna performance of the antenna FPC is a technical problem that needs to be solved. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an electronic device that can reduce the space occupied by the printed circuit board of the antenna assembly and increase the back cavity volume of the speaker.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides an electronic device, including:

[0008] A speaker assembly, the speaker assembly comprising a housing and a speaker unit disposed in the housing;

[0009] An antenna assembly, wherein the antenna assembly is disposed on a side wall of the housing;

[0010] A frame is provided with an antenna radiator, and the antenna assembly is electrically connected to the antenna radiator.

[0011] In an embodiment of the present application, the antenna assembly is arranged on the side wall of the shell of the speaker assembly. Compared with the existing structural design, the space occupied by the antenna assembly can be reduced while ensuring the antenna performance. Under the same space conditions, the back cavity space of the speaker assembly in the embodiment of the present application is larger. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] 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.

[0022] 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. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0023] The control method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1 to 7 , an embodiment of the present invention provides an electronic device, including:

[0025] The speaker assembly 1 comprises a housing 11 and a speaker unit 12 disposed in the housing 11;

[0026] An antenna assembly 2, the antenna assembly 2 is arranged on a side wall of the housing 11;

[0027] The frame 5 has an antenna radiator disposed thereon, and the antenna assembly 2 is electrically connected to the antenna radiator.

[0028] like Figure 1 and Figure 7 As shown, the shell 11 includes an upper cover body 111 and a lower cover body 112 that are fixedly connected, and the upper cover body 111 and the lower cover body 112 enclose a storage space for the speaker unit 12; wherein the lower cover body 112 includes a bottom wall and a side wall, the antenna assembly 2 is arranged on the side wall, and the circuit board 22 in the antenna assembly 2 is arranged perpendicular to the thickness direction of the shell 11.

[0029] As an optional implementation method, the antenna assembly 2 is attached to the outer surface of the side wall so that the antenna assembly 2 is sandwiched between the antenna radiator and the side wall. Compared with the existing structural design of stacking the antenna assembly 2 and the shell 11 in the thickness direction of the electronic device, the solution of the present application, under the same spatial conditions, the volume of the back cavity space B of the speaker assembly 1 is larger.

[0030] As another optional implementation method, the antenna assembly 2 is embedded in the side wall so that the antenna assembly 2 reuses the thickness space of the side wall to reduce the back cavity space occupied by the antenna assembly 2 of the speaker assembly 1, so that under the same space conditions, the volume of the back cavity space B of the speaker assembly 1 is larger.

[0031] Furthermore, if the cavity space of the speaker assembly 1 is sufficient, the internal space of the electronic device can be given to the battery or the thickness of the entire device can be reduced, thereby achieving a light, thin and long battery life.

[0032] In some embodiments, the electronic device further includes: the antenna assembly 2 includes a circuit board 22 and an antenna shrapnel 21 disposed on the circuit board 22, and the antenna shrapnel 21 is exposed outside the housing 11;

[0033] The circuit board 22 is electrically connected to the antenna radiator through the antenna spring 21 .

[0034] For example, Figure 2 , Figure 4 and Figure 5 As shown, the antenna spring 21 is exposed on the outer surface of the side wall of the housing 11. Figure 5 and Figure 6 As shown, the antenna radiator is disposed on the frame 5 , and the antenna spring piece 21 is pressed and contacted with the side surface of the frame 5 , so that the antenna spring piece 21 is electrically connected to the antenna radiator.

[0035] In this way, the antenna spring 21 is pressed and connected to the side of the frame 5, which makes full use of the internal space of the frame 5 and greatly reduces the space occupied by the antenna assembly 2. While improving the antenna performance, it increases the back cavity space B of the speaker assembly 1, ensuring a good electroacoustic experience for users.

[0036] like Figure 5 and Figure 6 In the figure, a schematic diagram showing the positions of the rear cavity space B and the front cavity space A of the speaker assembly 1 is shown.

[0037] In some embodiments, the electronic device further comprises:

[0038] The flexible circuit board 3 is disposed in the housing 11 . The antenna assembly 2 and the speaker unit 12 are connected to the connector 4 through the flexible circuit board 3 . The connector 4 is exposed outside the housing 11 .

[0039] For example, Figure 1 As shown, the flexible circuit board 3 includes a first connection end 31, a second connection end 32 and a third connection end 33; wherein the first connection end 31 is electrically connected to the input end of the circuit board 22, and is used to transmit a radio frequency signal to the circuit board 22; the second connection end 32 and the third connection end 33 are respectively used to connect to the positive and negative electrodes of the speaker unit 12, and are used to supply power to the speaker unit 12. The speaker unit 12 and the input of the circuit board 22 are integrated into a flexible circuit board 3, and finally connected to an external circuit through the connector 4 on the flexible circuit board 3, such as being electrically connected to a sub-board circuit or a main board circuit through the connector 4. In this way, the coaxial line and the coaxial line seat can be omitted, the small-sized parts are reduced, and the assembly difficulty is reduced.

[0040] It should be pointed out that the transmission of the antenna signal and the power supply of the speaker unit 12 are both carried out through the integrated flexible circuit board 3, and the two can be transmitted simultaneously or in time-sharing; when the speaker unit 12 is working, the speaker unit 12 is powered by the flexible circuit board 3; when the antenna assembly is working, the radio frequency signal is transmitted to the circuit board 22 through the flexible circuit board 3.

[0041] For example, Figures 2 to 4 In the figure, the lower cover body 112 in the shell 11 includes a bottom wall and side walls, which surround a lower cavity of the shell 11, in which a speaker unit 12 and a flexible circuit board 3 are placed; wherein the flexible circuit board 3 is arranged in the surrounding space of the speaker unit 12 to avoid increasing the overall thickness of the shell 11.

[0042] In some embodiments, a plurality of positioning posts 113 are disposed in the housing 11 , and a plurality of positioning holes 30 are disposed on the flexible circuit board 3 . The positioning holes 30 are respectively disposed on the positioning posts 113 .

[0043] For example, Figures 2 to 4 In the figure, the lower cover 112 in the shell 11 forms a lower cavity, in which the speaker unit 12 and the flexible circuit board 3 are placed; wherein, a plurality of positioning posts 113 are arranged around the speaker unit 12, and a plurality of positioning holes 30 arranged on the flexible circuit board 3 are penetrated one by one through the positioning posts 113, and the flexible circuit board 3 is limited and fixed by the positioning posts 113.

[0044] After the speaker unit 12 and the flexible circuit board 3 are installed and fixed in the lower cover 1112, the upper cover 111 and the lower cover 112 are assembled together by ultrasonic welding to form a Figure 7 Electronic module shown.

[0045] In some embodiments, Figure 3 As shown, a first through hole 1122 is provided on the side wall, the antenna assembly 2 is arranged on the outer wall of the side wall, and the antenna assembly 2 is connected to the internal space of the shell 11 through the first through hole 1122; wherein the flexible circuit board 3 is electrically connected to the antenna assembly 2 through the first through hole 1122.

[0046] As an implementation method, the antenna assembly 2 is attached to the outer wall surface of the side wall, and a first through hole 1122 is opened on the outer wall, so that the flexible circuit board 3 arranged in the shell 11 is electrically connected to the antenna assembly 2 through the first through hole 1122.

[0047] As another implementation method, the antenna component 2 is embedded in the outer wall of the side wall, and a first through hole 1122 is opened on the inner wall of the side wall, so that the first through hole 1122 connects a local area of ​​the antenna component 2 with the internal space of the shell 11, so that the flexible circuit board 3 is electrically connected to the antenna component 2 through the first through hole 1122.

[0048] like Figures 1 to 7 As shown, in some embodiments, a first mounting groove 1121 is provided on the outer surface of the side wall, and the antenna assembly 2 is fixedly disposed in the first mounting groove 1121;

[0049] The first through hole 1122 is defined at the bottom of the first mounting slot 1121 . The first through hole 1122 connects the first mounting slot 1121 with the inner space of the housing 11 . The antenna spring 21 in the antenna assembly 2 protrudes from the notch of the first mounting slot 1121 .

[0050] In specific implementation, a first mounting groove 1121 is provided on the outer surface of the side wall of the housing 11, and the circuit board 22 is attached to the first mounting groove 1121 by double-sided adhesive. The circuit board 22 is provided with an antenna shrapnel 21, and the antenna shrapnel 21 is installed away from the first mounting groove 1121, so that the antenna shrapnel 21 is exposed outside the housing 11; further, a first through hole 1122 is provided at the bottom of the first mounting groove 1121, and the first through hole 1122 connects the first mounting groove 1121 with the internal space of the lower cover 112, that is, a part of the circuit board 22 is exposed in the internal space of the housing 11. In this way, the flexible circuit board 3 installed in the housing 11 can be electrically connected to the circuit board 22 by using the first connection end 31 to pass through the first through hole 1122, so as to transmit the radio frequency signal to the antenna assembly 2 through the flexible circuit board 3.

[0051] In the above embodiment, by embedding the circuit board 22 on the side wall and connecting it to the flexible circuit board 3 through the first through hole 1122 on the side wall, the space occupied by the circuit board 22 is reused as the side wall of the housing 11 of the speaker assembly 1, and the antenna shrapnel 21 is also pressed and connected to the side of the frame 5, so as to make full use of the internal space of the frame 5, greatly reduce the space occupied by the circuit board 22, increase the back cavity space B of the speaker assembly 1, and ensure the user's good electroacoustic experience while improving the antenna performance. Moreover, it can also avoid the problem that the circuit board 22 and the housing 11 connected by screws easily cause the circuit board 22 to swing, which affects the antenna performance.

[0052] In some other embodiments, a second mounting groove (not shown) is provided on the inner side surface of the side wall, and the antenna assembly 2 is fixedly disposed in the second mounting groove;

[0053] A second through hole (not shown) is formed at the bottom of the second mounting groove, and the second through hole communicates with the external space of the housing 11;

[0054] The antenna spring piece 21 in the antenna assembly 2 is disposed in the second through hole, and the antenna spring piece 21 protrudes from the second through hole.

[0055] In this embodiment, since the second mounting groove is arranged on the inner wall of the housing 11, the second mounting groove is connected to the internal space of the housing 11, and the flexible circuit board 3 arranged in the housing 11 can be directly electrically connected to the circuit board 22, and the antenna shrapnel 21 arranged on the circuit board 22 is exposed through the second through hole, so that the antenna shrapnel 21 is exposed outside the housing 11, which facilitates the electrical connection between the antenna shrapnel 21 and the antenna radiator. In this way, the position space occupied by the circuit board 22 can be reused by the side wall of the housing 11 of the speaker assembly 1, and the antenna shrapnel 21 is also pressed and connected with the side of the frame 5, making full use of the internal space of the frame 5, greatly reducing the space occupied by the circuit board 22, and increasing the back cavity space B of the speaker assembly 1, while achieving the improvement of antenna performance, ensuring a good electroacoustic experience for users.

[0056] In some embodiments, the connection position between the flexible circuit board 3 and the circuit board 22 is covered with a sealing layer 7 , and the sealing layer blocks the first through hole 1122 .

[0057] like Figure 5 As shown, after the flexible circuit board 3 and the circuit board 22 are welded, the sealing layer 7 is covered at the connection point to protect the welding position and prevent air leakage in the cavity.

[0058] Optionally, the sealing layer 7 is an ultraviolet (UV) adhesive layer. UV adhesive is a light-curing adhesive, the main component of which is a photosensitive resin. Its curing process depends on the irradiation of ultraviolet light. When the UV adhesive is exposed to ultraviolet light, the photosensitive components in the adhesive will undergo a chemical reaction, quickly solidify and form a hard adhesive layer.

[0059] In some embodiments, the antenna assembly 2 is injection molded on the side wall of the housing 11 .

[0060] like Figure 5 In the embodiment, the antenna assembly 2 is injection molded into the side wall of the housing 11 by low temperature injection molding, so that the antenna assembly 2 and the housing 11 are integrated into one component. Optionally, the housing 11 is made of plastic.

[0061] Alternatively, if Figure 5 In the embodiment, boss structures are respectively provided at both ends of the circuit board 22 so that the circuit board 22 can be tightly combined with the side wall.

[0062] In some embodiments, at least one anti-warping buckle a is provided at the opening edge of the first mounting groove 1121 , and the anti-warping buckle a resists the antenna assembly 2 .

[0063] For example, Figure 4 As shown, at the opening edge of the first mounting groove 1121 , an anti-warping buckle a is provided at an end away from the antenna shrapnel 21 , and the anti-warping buckle a is an elastic structure.

[0064] It should be pointed out that if the antenna shrapnel 21 is set in the middle of the circuit board 22, an anti-warping buckle a is required to be set at the two ends of the antenna shrapnel 21, corresponding to the opening edge of the first mounting groove 1121, so as to prevent the two ends of the circuit board 22 from warping up due to the pressure on the antenna shrapnel 21.

[0065] In a specific implementation, firstly, the double-sided adhesive tape is pasted and fixed in the first installation groove 1121 to form a Figure 6 The adhesive layer 6 shown is then used to install the antenna assembly 2 in the first installation groove 1121 by squeezing the anti-warping buckle a.

[0066] In this embodiment, in order to prevent the antenna shrapnel 21 from causing the risk of the circuit board 22 warping due to the side press connection during operation, at least one anti-warping buckle a is provided at the opening edge of the first mounting groove 1121. The anti-warping buckle a is pressed against the antenna assembly 2 to fix the antenna assembly 2 and prevent the antenna assembly 2 from warping. In addition, it can also avoid the problem that the antenna assembly 2 and the housing 11 are easily connected by screws, which may cause the antenna assembly 2 to swing and affect the antenna performance.

[0067] In some embodiments, the housing 11 is provided with a connecting buckle b at one end where the circuit board 22 is provided.

[0068] For example, Figure 2 , Figures 4 to 7 In the embodiment, the housing 11 is provided with a connecting buckle b on the side end face where the circuit board 22 is provided, and the frame 5 of the electronic device is provided with a card slot, and the connecting buckle b is connected with the card slot on the frame 5 of the electronic device to prevent the antenna assembly 2 from coming out in the thickness direction of the electronic device. The housing 11 is fixedly connected to the frame 5 by bolts at one end away from the circuit board 22.

[0069] For example, in some embodiments, Figure 1 In the figure, a plurality of sound outlet holes 51 are arranged on the frame 5, and a sound outlet 1123 is arranged on the lower cover 112 of the shell 11. When the shell 11 is installed in the receiving space formed by the frame 5, the sound outlet 1123 is connected with the sound outlet hole 51, so that the sound emitted by the speaker unit 12 is transmitted to the external environment through the sound outlet 1123 and the sound outlet hole 51 in sequence.

[0070] In some embodiments, the side wall of the housing 11 is integrated into the frame 5, and the antenna assembly 2 is embedded on the side wall, so that the internal space of the electronic device can be further increased.
