Description

Technical Field

[0001] The present invention relates to an electronic device, and in particular to an electronic device in which a speaker can be moved relative to a screen so that the speaker can be unfolded or folded on the screen. Background Art

[0002] At present, the display panel inside the back cover of laptop computers has a higher and higher display resolution, and the module size is becoming thinner and lighter. As the thickness of the back cover continues to decrease, there is no space inside the back cover to accommodate other modules except the display panel and camera module, wireless antenna group or light-emitting module. There is also a demand for a thin and light design on the base of the laptop computer. Given the design trend of laptop computers, the space for setting the speakers will be affected. At present, the speakers of laptop computers are all set inside the base. When the speakers play sound, they may be affected by the crowded structural space inside the base, resulting in poor sound quality. Therefore, how to balance the thin and light requirements of laptop computers and maintain the sound quality of the speakers is a problem that needs to be solved. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides an electronic device that can store a speaker in a screen assembly, thereby overcoming the defect of poor speaker sound quality caused by the crowded structural space inside the base.

[0004] In order to achieve the above-mentioned object, the present invention provides an electronic device in some embodiments. The electronic device includes a screen assembly, a speaker assembly and a switch assembly. The screen assembly includes a cover plate, and the cover plate has a first assembly portion. The speaker assembly includes a mounting plate and a speaker. The mounting plate has a second assembly portion, the first assembly portion is connected to the second assembly portion, and the mounting plate moves between a folded position and an extended position relative to the cover plate. The speaker is fixed to the mounting plate and activated according to a driving signal. The switch assembly is used to generate a driving signal when the mounting plate is in the extended position, and not generate a driving signal when the mounting plate is in the folded position.

[0005] In some embodiments, the electronic device further comprises an assembly member connected to the second assembly portion, and the assembly plate is connected to the cover plate through the assembly member.

[0006] In some embodiments, the first assembly portion is a slide groove, the second assembly portion is an assembly hole, one end of the assembly piece is against the slide groove, and the other end passes through the slide groove to connect to the assembly hole.

[0007] In summary, in some embodiments, an electronic device includes a screen assembly, a speaker assembly, and a switch assembly. The assembly plate of the speaker assembly can be moved relative to the screen assembly so that the assembly plate can be moved between a folded position and an extended position. When the assembly plate is in the folded position, the speaker of the speaker assembly can be hidden between the cover plate of the screen assembly and the assembly plate. When the assembly plate is in the extended position, the speaker can be exposed from the cover plate. Moreover, when the assembly plate is in the extended position, the switch assembly can generate a driving signal so that the speaker is turned on according to the driving signal. Thus, the speaker can be stored in the screen assembly by the design of relatively moving the cover plate, and the speaker can provide better playback quality. And the speaker can be automatically started by moving it to a specified position, which is easier for the user to operate.

[0047] Please also read Figure 1 , Figure 2 and Figure 3 . Figure 1 This is a three-dimensional diagram of an electronic device in the first embodiment of the present invention, showing that the assembly plate is in a folded position. Figure 2 This is a three-dimensional diagram of an electronic device in the first embodiment of the present invention, showing that the assembly plate is in an unfolded position. Figure 3 This is an exploded view of a speaker assembly in an electronic device in the first embodiment of the present invention. Figure 1 , Figure 2 and Figure 3 As shown, the electronic device 10 includes a screen assembly 102, a speaker assembly 104, and a switch assembly 106. The screen assembly 102 includes a cover plate 108, and the cover plate 108 has a first assembly portion 110. The speaker assembly 104 includes a connecting plate 112 and a speaker 114. The connecting plate 112 has a second assembly portion 116, and the first assembly portion 110 is connected to the second assembly portion 116, and the connecting plate 112 moves relative to the cover plate 108 to a retracted position P1 (for example, Figure 1 or Figure 6 The position of the middle assembly plate 112 relative to the cover plate 108) and an extended position P2 (eg Figure 2 or Figure 7 The speaker 114 is fixed to the assembly plate 112 and turned on according to a driving signal. The switch assembly 106 is used to generate a driving signal when the assembly plate 112 is in the extended position P2. It does not generate a driving signal when the assembly plate 112 is in the retracted position P1.

[0048] like Figure 2 As shown, in some embodiments, the electronic device 10 may be, for example, a notebook computer. The screen assembly 102 may include a screen 117, and the screen 117 has a display surface 118. The cover 108 is connected to a surface opposite to the display surface 118. The cover 108 may be, for example, a back panel of a notebook computer. The first assembly portion 110 may be disposed on one or both sides of the cover 108, such as Figure 1 As shown, the first assembly part 110 may be at least one, Figure 1The number of first assembling parts 110 is two. The two first assembling parts 110 can be respectively arranged on two sides of the cover plate 108, and the two first assembling parts 110 can be spaced apart by a distance. If the number of first assembling parts 110 is one, the first assembling part 110 can be arranged on the entire cover plate 108 (not shown). In addition, the number or position of the first assembling parts 110 can be determined according to the size of the speaker assembly 104. For example, if the length of the long side of a speaker assembly is less than half the length of the long side of a cover plate (see Figure 1 ), the cover plate 108 can be provided with first assembly parts 110 on both sides. On the contrary, if the length of the long side of the speaker assembly is greater than half the length of the long side of the cover plate, the cover plate 108 can be provided with one first assembly part 110.

[0049] The speaker 114 of the speaker assembly 104 can be a thin speaker. The thin speaker can be a piezoelectric speaker, a static speaker, an electromagnetic speaker, a ribbon speaker, or a flat speaker. It should be noted that the speaker assembly 104 can be made according to the thickness of the assembly plate 112 (such as Figure 1 The thickness of the middle assembly plate 112 on the Y axis), the thickness of the first assembly portion 110 (such as Figure 1 The speaker 114 of matching size is selected according to the drop distance between the middle cover plate 108 and the first assembly part 110 on the Y axis. In addition, in some embodiments, the speaker assembly 104 is at least one. For example Figure 2 or Figure 7 There are two speaker assemblies 104. There may also be more than two speaker assemblies 104. Figure 2 For example, the two speaker assemblies 104 are configured to be deployed horizontally. Figure 2 Based on the structure, a third speaker assembly 104 configured to be expanded in a vertical direction is added.

[0050] After the assembly plate 112 is connected to the cover plate 108, the assembly plate 112 can move from the folded position P1 to the extended position P2 relative to the cover plate 108. The user can operate the position of the assembly plate 112 to expose the speaker 114 to the first assembly portion 110 or fold it between the first assembly portion 110 and the second assembly portion 116. As mentioned above (the assembly plate 112 can move from the folded position P1 to the extended position P2 relative to the cover plate 108), the assembly plate 112 can move from the folded position P1 to the extended position P2 in an axial sliding manner (later in Figures 1 to 5 ), or it can be moved from the folded position P1 to the unfolded position P2 (later in Figures 6 to 10 illustrate).

[0051] The electronic device 10 includes a host 119 for generating an audio signal. The host 119 and the screen assembly 102 are pivotally arranged with each other, and the host 119 can transmit the audio signal to the speaker assembly 104, so that the speaker assembly 104 plays the audio signal. In some embodiments, the switch assembly 106 is coupled to the speaker 114 to control the activation or deactivation of the speaker 114. The switch assembly 106 can be, for example, a distance sensor, a light sensor, a magnetic switch or a spring switch. As mentioned above (the switch assembly 106 is used to generate a driving signal when the assembly plate 112 is located at the unfolded position P2, and does not generate a driving signal when the assembly plate 112 is located at the folded position P1), the switch assembly 106 can switch the switch mode according to the position of the assembly plate 112 (folded position P1 or unfolded position P2). And the switch assembly 106 can be configured on the cover plate 108 or the assembly plate 112, and coupled to the speaker 114 by a signal transmission line (described later). Specifically, the switch assembly 106 may be connected to the cover plate 108, and the switch assembly 106 is triggered by the assembly plate 112. The switch assembly 106 may also be connected to the assembly plate 112, and the switch assembly 106 is triggered by the cover plate 108.

[0052] Taking the switch component 106 as a distance sensor, if the switch component 106 is connected to the assembly plate 112, when the assembly plate 112 is located at the folded position P1, the infrared ray emitted by the switch component 106 is a preset distance to the cover plate 108. When the assembly plate 112 is located at the unfolded position P2, when the infrared reflection distance of the switch component 106 changes (for example, exceeds the default distance), the switch component 106 generates a driving signal. On the contrary, if the switch component 106 is connected to the cover plate 108, when the assembly plate 112 is located at the folded position P1, the switch component 106 can detect the assembly plate 112 (equal to the preset distance). When the assembly plate 112 is located at the unfolded position P2, the infrared reflection distance of the switch component 106 changes (greater than the default distance), and the switch component 106 generates a driving signal.

[0053] Taking the switch assembly 106 as a spring switch as an example, if the switch assembly 106 is connected to the assembly plate 112, when the cover plate 108 is located at the folded position P1, the cover plate 108 will press against the switch assembly 106, and at this moment, the switch assembly 106 does not generate a driving signal. When the assembly plate 112 is located at the unfolded position P2, the switch assembly 106 will no longer be pressed against by the cover plate 108, so that the switch assembly 106 is reset and generates a driving signal. On the contrary, if the switch assembly 106 is connected to the cover plate 108, when the cover plate 108 is located at the folded position P1, the assembly plate 112 will press against the switch assembly 106, and at this moment, the switch assembly 106 does not generate a driving signal. When the assembly plate 112 is located at the unfolded position P2, the switch assembly 106 will no longer be pressed against by the assembly plate 112, so that the switch assembly 106 is reset and generates a driving signal.

[0054] Taking the switch assembly 106 as a magnetic switch as an example, if the switch assembly 106 is connected to the assembly plate 112, when the assembly plate 112 is located at the folded position P1, the switch assembly 106 can generate a magnetic force with the cover plate 108, and at this moment, the switch assembly 106 does not generate a driving signal. When the assembly plate 112 is located at the unfolded position P2, the switch assembly 106 no longer generates a magnetic force with the cover plate 108, and the switch assembly 106 generates a driving signal. Conversely, if the switch assembly 106 is connected to the cover plate 108, when the assembly plate 112 is located at the folded position P1, the switch assembly 106 can generate a magnetic force with the assembly plate 112, and at this moment, the switch assembly 106 does not generate a driving signal. When the assembly plate 112 is located at the unfolded position P2, the switch assembly 106 no longer generates a magnetic force with the assembly plate 112, and the switch assembly 106 generates a driving signal.

[0055] Please also read Figure 3 , Figure 4 and Figure 5 . Figure 4 This is a schematic diagram of an electronic device according to the first embodiment of the present invention, showing the position of the assembly member relative to the first assembly portion when the assembly plate is in the folded position. Figure 5 1 is a schematic diagram of an implementation of an electronic device in the first embodiment of the present invention, showing the position of the assembly relative to the first assembly portion when the assembly plate is in the unfolded position. In some embodiments, the electronic device 10 further includes an assembly 120. The assembly 120 is connected to the second assembly portion 116, and the assembly plate 112 is directly or indirectly connected to the cover plate 108 through the assembly 120. Among them, the assembly 120 can be a track roller, a track slider or a hollow bearing. In some embodiments, the first assembly portion 110 is a slide groove, the second assembly portion 116 is an assembly hole, one end of the assembly 120 is against the first assembly portion 110, and the other end passes through the first assembly portion 110 to connect the second assembly portion 116. Specifically, in this embodiment, the assembly 120 can be a track roller. After the user pulls the assembly plate 112, the assembly plate 112 drives the assembly 120, and the assembly plate 112 and the assembly 120 can move along the first assembly portion 110. The two ends of the first assembly portion 110 are respectively disposed at the folded position P1 and the extended position P2, so that the assembly plate 112 can move between the folded position P1 and the extended position P2. Figure 2 As shown, the assembly plate 112 moves along the X-axis direction in the figure. In other embodiments, the first assembly portion 110 can also move along Figure 2 The Y-axis direction is arranged so that the assembly plate 112 moves along the Y-axis direction.

[0056] For example Figure 4 and Figure 5As shown, in some embodiments, the cover plate 108 has an actuating portion 122, and when the assembly plate 112 is located at the unfolded position P2, the switch component 106 is triggered by the actuating portion 122 to generate a driving signal. The actuating portion 122 may be a stopper or a through hole formed on the cover plate 108, or may be a ferromagnetic component connected to the cover plate 108. For example, when the switch component 106 is a magnetic switch and the actuating portion 122 is a ferromagnetic component, when the assembly plate 112 is located at the folded position P1, the switch component 106 is not actuated (here, the actuating condition of the switch component 106 may be that the magnetic switch is acted upon by a magnetic force). When the assembly plate 112 is located at the unfolded position P2, the switch component 106 corresponds to the position of the actuating portion 122 (ferromagnetic component), and the switch component 106 and the actuating portion 122 are actuated under the action of the magnetic force to generate a driving signal. Taking the switch component 106 as a light sensor and the actuating portion 122 as a through hole as an example, when the assembly plate 112 is located at the folded position P1, the switch component 106 is not actuated (the actuation condition of the switch component 106 may be that the infrared light of the light sensor changes). When the assembly plate 112 is located at the unfolded position P2, the switch component 106 corresponds to the position of the through hole, and the infrared light of the switch component 106 passes through the through hole, causing the distance detected by the switch component 106 to change (reach the actuation condition) and be actuated to generate a driving signal. Taking the switch component 106 as a spring switch and the actuating portion 122 as a stopper as an example, when the assembly plate 112 is located at the folded position P1, the switch component 106 is not actuated (here, the actuation condition of the switch component 106 may be pressing the spring switch). When the assembly plate 112 is located at the unfolded position P2 , the switch component 106 corresponds to the position of the stopper of the actuating portion 122 , and the switch component 106 is actuated by the actuating portion 122 to generate a driving signal.

[0057] For example Figure 4 As shown, in some embodiments, the speaker assembly 104 further includes a structural member 124, and the structural member 124 is connected to the assembly plate 112. The structural member 124 has a second assembly portion 116 (for example, an assembly hole), a fixing portion 126, and a switch portion 128. The speaker 114 is connected to the fixing portion 126, and the switch assembly 106 is connected to the switch portion 128. The other end of the assembly member 120 passes through the first assembly portion 110 (for example, a slide groove) to connect the second assembly portion 116. It should be noted that when the assembly plate 112 is located at the folded position P1, the speaker 114 is located between the cover plate 108 and the assembly plate 112, so that the speaker 114 is shielded by the cover plate 108. When the assembly plate 112 is located at the unfolded position P2, the speaker 114 can be exposed from the cover plate 108, and the switch portion 128 overlaps with the actuating portion 122, so that the switch assembly 106 is actuated by the actuating portion 122.

[0058] Please also read Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments, Figure 3 As shown, the second assembly portion 116 (assembly hole) has a first opening 130, and the assembly member 120 has a second opening 132, and the first opening 130 overlaps with the second opening 132. In some embodiments, the electronic device 10 further includes a signal transmission line 134, and the signal transmission line 134 can pass through the first assembly portion 110 to couple to the speaker 114, and the signal transmission line 134 can also pass through the second assembly portion 116 to couple to the speaker 114. Figure 4 As shown in FIG. 1 , when the assembly plate 112 is located at the folded position P1 , the signal transmission line 134 can be located at any position of the first assembly portion 110 . Figure 5 As shown in FIG. 1 , during the process of the assembly plate 112 moving from the folded position P1 to the unfolded position P2, the assembly member 120 pushes the signal transmission line 134 to the unfolded position P2. Finally, when the assembly plate 112 moves to the unfolded position P2, the signal transmission line 134 passes through the first opening 130 and the second opening 132 (the first opening 130 and the second opening 132 overlap, and the signal transmission line 134 passes through the first opening 130 and the second opening 132). Figure 3 and Figure 4 Only the second opening 132 is indicated in the figure) and is accommodated in the second assembly portion 116 (assembly hole), so that the signal transmission line 134 will not be squeezed by the assembly member 120 and the first assembly portion 110 (slide groove), thereby preventing the signal transmission line 134 from being squeezed and damaged.

[0059] Please also read Figure 6 , Figure 7 and Figure 8 . Figure 6 This is a three-dimensional diagram of an electronic device in the second embodiment of the present invention, showing that the assembly plate is in a folded position. Figure 7 This is a three-dimensional diagram of an electronic device in a second embodiment of the present invention, showing that the assembly plate is in an unfolded position. Figure 8 This is an exploded view of a speaker assembly in an electronic device in the second embodiment of the present invention. Figure 6 , Figure 7 and Figure 8 As shown, the difference between the second embodiment and the first embodiment lies in the connection method of the screen assembly 102, the speaker assembly 104 and the assembly 120, and the assembly plate 112 is moved from the folded position P1 to the unfolded position P2 in a pivoting manner. Specifically, in the second embodiment, the first assembly portion 110 is a first assembly hole, the second assembly portion 116 is a second assembly hole, and the assembly 120 is a hollow bearing. The two ends of the assembly 120 are respectively pivotally connected to the first assembly portion 110 and the second assembly portion 116, so that the assembly plate 112 can rotate relative to the cover plate 108 through the assembly 120.

[0060] Please also read Fig. 9 and Fig.10 . Fig. 9 This is a schematic diagram of an electronic device according to a second embodiment of the present invention, showing the position of the assembly member relative to the first assembly portion when the assembly plate is in the folded position. Fig.10 This is a schematic diagram of an electronic device according to a second embodiment of the present invention, showing the position of the assembly member relative to the first assembly portion when the assembly plate is in the unfolded position. Fig. 9 and Fig.10 As shown, in this embodiment, the signal transmission line 134 passes through a hollow portion 136 of the assembly 120 and is coupled to the speaker 114, so that when the assembly plate 112 rotates relative to the cover plate 108, the signal transmission line 134 will not rotate with the assembly plate 112. Therefore, the signal transmission line 134 can be protected by the hollow portion 136 and will not be damaged by interference (such as squeezing) from the cover plate 108 or the assembly plate 112. In addition, when the user rotates the assembly plate 112 to rotate the assembly plate 112 from the folded position P1 to the unfolded position P2, the switch assembly 106 will not be actuated (the speaker 114 has not been driven). When the assembly plate 112 rotates to the unfolded position P2, the actuating portion 122 and the switch assembly 106 are located on the same axis. At this moment, the switch assembly 106 can be actuated by the actuating portion 122 to generate a driving signal, so that the speaker 114 can be activated according to the driving signal. The description of the actuation of the switch assembly 106 and the actuation portion 122 can be referred to the description of the first embodiment, which will not be repeated here.

[0061] For example Fig. 9 As shown, in some embodiments, the assembly 120 has two wings (138, 140), and the two wings (138, 140) extend out of the hollow portion 136. One diameter of the first assembly portion 110 and the second assembly portion 116 is a first length L1, and the distance between the two wings (138, 140) is a second length L2, and the second length L2 is greater than the first length L1. This allows the assembly 120 to remain in the first assembly portion 110 (or the second assembly portion 116) during the rotation process.

[0062] For example Fig. 9 and Fig.10 As shown, in some embodiments, the structural member 124 of the speaker assembly 104 is connected to the assembly plate 112, and the structural member 124 has a fixing portion 126, and the speaker 114 is connected to the fixing portion 126. It should be noted that when the assembly plate 112 is located at the folded position P1, the speaker 114 is located between the cover plate 108 and the assembly plate 112, so that the speaker 114 is shielded by the cover plate 108. When the assembly plate 112 is rotated to the unfolded position P2, the speaker 114 can be partially or completely exposed from the cover plate 108. Among them, the shape of the speaker 114 can be determined according to the area of ​​the speaker 114 exposed from the cover plate 108, so that the speaker 114 can fit the shape of the cover plate 108 and be completely exposed from the cover plate 108.

[0063] Please refer to Figure 3 and Figure 8 The electronic device 10 further includes a dust screen 142. The dust screen 142 is connected to the structure 124. When the assembly plate 112 is located at the folded position P1, the dust screen 142 is located between the speaker 114 and the cover 108. When the assembly plate 112 is located at the unfolded position P2, the dust screen 142 can cover the speaker 114 to prevent dust from adhering to the speaker 114.

[0064] In summary, in some embodiments, an electronic device 10 includes a screen assembly 102, a speaker assembly 104, and a switch assembly 106. The assembly plate 112 of the speaker assembly 104 can move relative to the screen assembly 102, so that the assembly plate 112 can move between the folded position P1 and the unfolded position P2. The assembly plate 112 is connected to the cover plate 108 through the assembly 120, so that the assembly plate 112 can move relative to the cover plate 108. For example, when the assembly 120 is a track slider and the first assembly portion 110 of the cover plate 108 is a slide groove, the assembly plate 112 can move axially relative to the cover plate 108. When the assembly 120 is a hollow bearing, the assembly plate 112 can be pivoted to the cover plate 108 through the hollow bearing, so that the assembly plate 112 can pivot relative to the cover plate 108. In this way, the assembly plate 112 is stored or unfolded on the cover plate 108. In addition, when the assembly plate 112 is at the unfolded position P2, the switch assembly 106 can generate a driving signal to turn on the speaker 114 according to the driving signal. Thus, the speaker 114 can be automatically turned on and off by moving it to a designated position, making it easier for the user to operate.

[0065] Although the technical contents of the present invention have been disclosed as above in the preferred embodiments, they are not used to limit the present invention. Slight changes and modifications made by those skilled in the art without departing from the spirit of the present invention should all be included in the scope of the present invention.
