Description

Technical Field

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

[0002] Electronic devices play audio through speakers so that users can hear the sound. In order to improve the playback effect, some electronic devices use a dual speaker structure, that is, two sound-generating devices are provided in the electronic device. Since the sound cavities of the two sound-generating devices cannot be connected to each other, generally in electronic devices, one sound-generating device uses an open sound cavity and the other sound-generating device uses a closed sound cavity. However, the closed sound cavity is large in the thickness direction of the electronic device, so it is not conducive to the thinning of the electronic device. Summary of the invention

[0003] An embodiment of the present application provides an electronic device for solving the problem that when a sound-generating device of the electronic device adopts a closed sound cavity, the size in the thickness direction of the electronic device is large, which is not conducive to the thinning of the electronic device.

The isolating portion is disposed in the first cavity, and the isolating portion separates the first cavity into a first cavity and a second cavity that are independent of each other, the distribution direction of the first cavity and the second cavity is parallel to the middle plate, and the back cover forms a wall plate of the first cavity and the second cavity. The first sound-emitting device is disposed on the portion of the middle plate that encloses the first cavity, and the first cavity forms a back cavity of the first sound-emitting device. The second sound-emitting device is disposed on the portion of the middle plate that encloses the second cavity, and the second cavity forms a back cavity of the second sound-emitting device.

In addition, since the first cavity and the second cavity are independent of each other, it is possible to avoid the sound waves emitted by the first sound-emitting device from interfering with the sound waves emitted by the second sound-emitting device, which is beneficial to improving the audio effect of the electronic device.

[0058] From the above, please refer to Figure 1 , Figure 1 A structural diagram of an electronic device 10 provided in an embodiment of the present application. In the present embodiment, the electronic device 10 is a mobile phone, and the electronic device 10 can be approximately in the shape of a rectangular plate. On this basis, in order to facilitate the description of each embodiment below, an XYZ coordinate system is established, and the width direction of the electronic device 10 is defined as the X-axis direction, the length direction of the electronic device 10 is defined as the Y-axis direction, and the thickness direction of the electronic device 10 is defined as the Z-axis direction. It can be understood that the coordinate system of the electronic device 10 can be flexibly set according to actual needs, and this application only gives an example, which cannot be considered as a special limitation on the present application.

In addition, a socket 221 is provided at a position corresponding to the USB device 410 on the frame 220, and accessories such as a charger, earphones, and a data cable can be electrically connected to the USB device 410 via the socket 221 to achieve transmission of power, signals, and data.

[0070] The battery 600 is fixed in the receiving space 700 of the electronic device 10. The battery 600 is located between the main circuit board 300 and the width circuit board. The battery 600 is used to provide power for the main circuit board 300, the width circuit board, the screen, and the sound device.

[0071] The battery 600 may include but is not limited to a nickel-cadmium battery 600, a nickel-metal hydride battery 600, a lithium battery 600 or other types of batteries including bare cells 600. In addition, the number of the battery 600 in the embodiment of the present application may be multiple or one, and the specific number and arrangement of the battery 600 in the embodiment of the present application may be set according to actual needs.

[0072] The above-mentioned sound-generating device is used to play audio for the electronic device 10, so that the electronic device 10 can support external audio. The sound-generating device may include a speaker 500 or a receiver, etc. In this embodiment, the sound-generating device is taken as an example of a speaker 500 for detailed description.

[0073] The above-mentioned speaker 500 produces sound by vibrating the internal diaphragm. Since the speaker 500 is arranged in the shell 200 of the electronic device 10, it is necessary to set a sound cavity inside the shell 200. Specifically, the sound cavity includes a front sound cavity and a rear sound cavity that are arranged on both sides of the diaphragm of the speaker 500 and are independent of each other. The front sound cavity is connected to the sound outlet hole opened on the frame 220 of the shell 200 so that the sound can be transmitted to the outside of the shell 200; the rear sound cavity is used to balance the vibration of the diaphragm of the speaker 500 to the rear side, to avoid the vibration of the diaphragm to the rear side of the sound cavity, and to generate noise due to the compression of the air in the rear sound cavity, which is conducive to optimizing the audio effect of the speaker 500.

[0074] In some embodiments, two speakers 500 can be provided, namely a first speaker 510 and a second speaker 520. The first speaker 510 is provided at the top of the electronic device 10 and is electrically connected to the main circuit board 300; the second speaker 520 is provided at the bottom of the electronic device 10 and is electrically connected to the auxiliary circuit board 400.

[0075] A first front sound cavity 511 and a first rear sound cavity 512 are provided inside the shell 200 corresponding to the first speaker 510, and a second front sound cavity 521 and a second rear sound cavity 522 are provided corresponding to the second speaker 520. A first sound outlet hole 222 communicating with the first front sound cavity 511 is provided on the top surface of the frame 220, and a second sound outlet hole 223 communicating with the second front sound cavity 521 is provided on the bottom surface of the frame 220.

[0076] Since each sound cavity needs to be independent from each other, in order to avoid mutual interference of sound and affect the audio effect of the speaker 500. Therefore, please refer to Figure 3 , Figure 3 A cross-sectional structural diagram of an electronic device 10 provided for related art. In related art, the first rear sound cavity 512 of the first speaker 510 is an open sound cavity, that is, the space between the rear cover 210 and the middle plate 230 is used as the first rear sound cavity 512 of the first speaker 510; at the same time, the second rear sound cavity 522 of the second speaker 520 is a closed sound cavity, that is, a first structural member 001 is arranged inside, and a closed space is formed inside the housing 200 through the first structural member 001, and the second speaker 520 is arranged in the closed space as the second rear sound cavity 522 of the second speaker 520, so that the first rear sound cavity 512 and the second rear sound cavity 522 are independent of each other. However, the closed sound cavity (i.e., the first structural member 001) needs to occupy a large space inside the electronic device 10, which is not conducive to the thinness of the electronic device 10.

[0077] Based on this, see Figure 4 and Figure 5 , Figure 4 A rear view of an electronic device 10 (a rear cover 210 is not shown in the figure) provided in an embodiment of the present application. Figure 5 for Figure 4 AA cross-sectional view of the provided electronic device 10. It should be noted that the cross-sectional views in the present application have all adjusted the size ratios in the Z-axis direction to make the structures in the views clearer, and therefore, the size ratios in the drawings do not have any limiting effect on the size of the actual product.

[0078] Please continue reading Figure 4 and Figure 5 The embodiment of the present application provides an electronic device 10, which includes a housing assembly, in which a battery 600, a first speaker 510 and a second speaker 520 are arranged. The housing assembly 200 includes a display module 100, a back cover 210, a frame 220, a middle plate 230 and an isolation portion 800.

[0079] Specifically, the middle plate 230 divides the accommodation space into a first cavity 720 and a second cavity 710. The battery 600 is disposed in the second cavity 710, and the isolation portion 800 is disposed in the first cavity 720, and the isolation portion 800 divides the first cavity 720 into a mutually independent first chamber 721 and a second chamber 722. The first speaker 510 is disposed in an area outside the second cavity 722 (including the first chamber 721 and the second cavity 710), and the second speaker 520 is disposed in the second cavity 722.

[0080] In this way, the electronic device 10 provided in the embodiment of the present application divides the first cavity 720 into a first cavity 721 and a second cavity 722 which are independent of each other through the isolation portion 800, and respectively arranges the first speaker 510 and the second speaker 520 in an area outside the second cavity 722 and in the second cavity 722 to form a first rear sound cavity 512 and a second rear sound cavity 522 of the first speaker 510 and the second speaker 520, respectively, and both the first rear sound cavity 512 and the second rear sound cavity 522 are open sound cavities, which is beneficial to saving space and thus conducive to the slimness of the overall device.

[0081] In addition, the battery 600 and the isolation part 800 are respectively arranged on both sides of the middle plate 230, that is, the isolation part 800 is arranged in the first cavity 720, and the battery 600 is arranged in the second cavity 710. In this way, since the battery 600 is not arranged in the first cavity 720, there will be no gap in the second cavity 710 (for example, the gap between the battery 600 and the frame 220), so the isolation part 800 can completely separate the first cavity 720 into the first cavity 721 and the second cavity 722, thereby preventing the first cavity 721 and the second cavity 722 from being connected to each other.

[0082] At the same time, when the isolation part 800 is subjected to a large extrusion force, since the battery 600 is in the second cavity 710, it will not affect the battery 600. Moreover, the battery 600 is arranged in the second cavity 710, so as to reserve an expansion gap for the battery 600 to accommodate the expansion of the battery 600, thereby preventing the expansion of the battery 600 from causing deformation of the housing 200. In some embodiments, graphite sheets, heat-conducting heat pipes, wireless charging coils, screen FPC (flexible circuit board for connecting the display screen 120 and the main circuit board 300), buffer foam and other devices may also be arranged in the above-mentioned second cavity 710. Graphite sheets, heat-conducting heat pipes, wireless charging coils, main FPC (FPC board for connecting the main circuit board 300 and the auxiliary circuit board 400) and other devices may also be arranged in the above-mentioned first cavity.

[0083] In some embodiments, the isolation part 800 may include adhesive or foam or glue, and is extended along the X-axis direction to separate the first cavity 720 into a first cavity 721 and a second cavity 722 distributed along the Y-axis direction. On the one hand, the first cavity 721 and the second cavity 722 can be separated from each other, and on the other hand, it is helpful to save the material of the isolation part 800.

[0084] In addition, the back cover 210 and the middle plate 230 are fixed by adhesive bonding. For example, the isolation part 800 can adopt adhesive bonding. At the same time, the isolation part 800 can be integrated with the adhesive bonding arranged between the back cover 210 and the middle plate 230 to improve the sealing performance of the isolation part 800.

[0085] Furthermore, since the main circuit board 300 is disposed in the first cavity 721 and the auxiliary circuit board 400 is disposed in the second cavity 722, the two are electrically connected via the FPC board; therefore, the portion where the isolation portion 800 intersects with the FPC board can be sealed by a dispensing process to ensure that the first cavity 721 and the second cavity 722 are independent of each other. Alternatively, the sealing can also be performed by foam pressing. It is understandable that when foam pressing is performed, there may be a small gap, but the gap will not affect the audio effect of the two speakers, that is, a slight leakage is allowed between the first cavity 721 and the second cavity 722.

[0086] Also, please read Figure 4 and Figure 5 , the isolation part 800 and the battery 600 are respectively arranged on both sides of the middle plate 230, and the vertical projection of the battery 600 on the rear cover 210 (i.e., the vertical projection in the XY plane) covers the vertical projection of the isolation part 800 on the rear cover 210 along the Y-axis direction. In this way, it is possible to avoid the isolation part 800 having an overlapping area with the main circuit board 300 or the auxiliary circuit board 400 in the XY plane, so as to avoid the isolation part 800 affecting the installation of the main circuit board 300 or the auxiliary circuit board 400.

[0087] In some embodiments, the second cavity 710 may be disposed between the display module 100 and the middle plate 230 , and the first cavity 720 may be disposed between the middle plate 230 and the back cover 210 . Furthermore, the first speaker 510 may be disposed in the first cavity 721 , and the second speaker 520 may be disposed in the second cavity 722 .

[0088] Specifically, see Figure 6 , Figure 6 for Figure 5An enlarged view of area B of the electronic device 10 is provided. The first speaker 510 is fixed to the middle plate 230 by a sealing member such as foam or adhesive, and a first connecting notch 234 is provided on the middle plate 230, and the first connecting notch 234 is connected to the first sound outlet 222 to form a first front sound cavity 511 of the first speaker 510; at the same time, the middle plate 230 and the display module 100 can be bonded and fixed by an adhesive layer 130 (such as adhesive or dispensing or a combination of the two), and the adhesive layer 130 is extended along a circle of the middle plate 230, and the part of the adhesive layer 130 located at the first connecting notch 234 extends along the edge of the first connecting notch 234, so that the first front sound cavity 511 is separated from the second cavity 710, thereby forming an independent first front sound cavity 511.

[0089] At the same time, at the position corresponding to the first speaker 510, there may be a certain gap between the frame 220 and the display module 100, i.e., a sound outlet gap 224, so that the sound emitted by the first speaker 510 can be diffused to the outside of the first front sound cavity 511 through the sound outlet gap 224. Moreover, after the volume of the first speaker 510 is reduced, it can be used as an earpiece at the same time, so an earpiece may not be provided separately.

[0090] The main circuit board 300 is also disposed in the first cavity 721, and a connection notch 236 is provided on the middle plate 230, so that the connection structure (such as an FPC board) between the display module 100 and the main circuit board 300 passes through the connection notch 236 and connects the display module 100 and the main circuit board 300. Since the connection notch 236 connects the first cavity 721 with the second cavity 710, the first cavity 721 and the second cavity 710 together form the first rear sound cavity 512 of the first speaker 510.

[0091] It should be noted that a plurality of connection gaps 236 can be provided, and the connection gaps 236 can also be used to avoid other devices (for example, a shielding cover or a camera module, etc.). The specific number of the connection gaps 236 can be determined based on the volume size and specific structural layout of the other devices. Therefore, the present application does not specifically limit the number of connection gaps 236.

[0092] See also Figure 7 , Figure 7 for Figure 5An enlarged view of the C area of ​​the electronic device 10 is provided. The second speaker 520 can also be fixed to the middle plate 230 by a sealing member such as foam or adhesive. A second connecting notch 235 is provided in the middle plate 230 in the area corresponding to the second speaker 520. The second connecting notch 235 is connected to the second sound outlet 223 on the bottom surface of the frame 220 to form a second front sound cavity 521 of the second speaker 520. At the same time, the adhesive layer 130 between the middle plate 230 and the display module 100, the part located at the second connecting notch 235, extends along the edge of the second connecting notch 235 to separate the second front sound cavity 521 from the second cavity 710, thereby forming an independent second front sound cavity 521.

[0093] The auxiliary circuit board 400 is disposed in the second cavity 722, and the second speaker 520 is electrically connected to the auxiliary circuit board 400. At this time, the second cavity 722 is separated from the first rear sound cavity 512 and the second front sound cavity 521, thereby forming an independent second rear sound cavity 522. In addition, the sound outlet gap 224 may also be disposed at the second front sound cavity 521, and its specific structure is the same as that of the first front sound cavity 511, so it will not be described repeatedly.

[0094] In this way, a first rear sound cavity 512 and a second rear sound cavity 522 that are independent of each other can be formed inside the electronic device 10 so that the sound waves emitted by the first speaker 510 and the second speaker 520 will not interfere with each other, thereby improving the audio effect of the electronic device 10.

[0095] In other embodiments, see Figure 8 , Figure 8 Another structural diagram of the second front sound cavity 521 provided for the application embodiment. The second front sound cavity 521 can also be formed by the following structure: a second structural member 522a is provided in the second chamber 722, a groove 522b for accommodating the second speaker 520 is provided on the second structural member 522a, a gap is provided between the second speaker 520 and the bottom surface of the groove 522b, i.e., the second front sound cavity 521, and a sound outlet channel 522c for connecting the second front sound cavity 521 and the second sound outlet hole 223 is provided on the side wall of the groove 522b, so that the second front sound cavity 521 is connected with the second sound outlet hole 223.

[0096] Furthermore, the second structural member 522a and the frame 220 can be sealed by a sealing portion 522d, and the sealing portion 522d is arranged around the circumference of the sound outlet channel 522c to prevent the sound outlet channel 522c from communicating with the second chamber 722. Exemplarily, the sealing portion 522d may include adhesive or foam. It should be noted that the first front sound cavity 511 may also be formed by the above structure, which will not be described again here.

[0097] On this basis, see Fig. 9 , Fig. 9 A cross-sectional view of another electronic device 10 provided in an embodiment of the present application (the battery 600, the first speaker 510, the main circuit board 300, and the second speaker 520 are not shown in the figure). To facilitate the installation of the battery 600, the main circuit board 300, the first speaker 510, the auxiliary circuit board 400, and the second speaker 520, the surface of the middle plate 230 facing the display module 100 is recessed toward the back cover 210 to form a receiving groove 231; the surface of the middle plate 230 facing the back cover 210 is recessed toward the display module 100 to form a first groove 232 and a second groove 233. Among them, the receiving groove 231 is used to install Figure 5 The battery 600 shown in the figure has a first groove 232 for mounting Figure 4 and Figure 5 The main circuit board 300 and the first speaker 510 are shown, and the second groove 233 is used to install Figure 4 and Figure 5 The auxiliary circuit board 400 and the second speaker 520 are shown. In this way, the thickness of the electronic device 10, that is, the dimension in the Z-axis direction, can be reduced, which is conducive to making the electronic device 10 lighter and thinner.

[0098] In addition, in this embodiment, a shock absorbing layer (not shown in the figure) may be further provided in the first cavity 720, such as foam or adhesive or glue. That is, the shock absorbing layer is provided between the middle plate 230 and the back cover 210. Since the battery 600 is provided in the second cavity 710, the shock absorbing layer will not squeeze the battery 600 and will not be affected by the expansion of the battery 600. Therefore, the shock absorbing layer can withstand a large squeezing force between the middle plate 230 and the back cover 210, which is conducive to eliminating the vibration of the back cover 210 caused by the sound waves in the back sound cavity of the speaker 500, and is conducive to further improving the user experience.

[0099] It should be noted that when the electronic components in the second cavity 710 fill the second cavity 710 completely, or the middle plate 230 is completely attached to the display module 100, that is, there is no cavity in the second cavity 710. In this case, the first rear sound cavity of the first speaker 510 can be formed by the first cavity 721 only, and the second rear sound cavity 522 of the second speaker 520 can be formed by the second cavity 722.

[0100] Moreover, when the above-mentioned connecting notch 236 is not provided on the middle plate 230, that is, the first cavity 721 and the second cavity 710 are not connected to each other, at this time, the first rear sound cavity of the first speaker 510 is also formed by the first cavity 721, and the second rear sound cavity 522 of the second speaker 520 is formed by the second cavity 722.

[0101] In other embodiments, see Fig.10 , Fig.10A cross-sectional view of another electronic device 10 provided in an embodiment of the present application. The above-mentioned first speaker 510 and the main circuit board 300 can be arranged in the second cavity 710, that is, the first groove 232 and the receiving groove 231 are both arranged on the surface of the middle plate 230 facing the display module 100, and the first speaker 510 and the main circuit board 300 are both arranged between the middle plate 230 and the display module 100. In this case, the side of the diaphragm of the first speaker 510 facing the middle plate 230 is the front side, and the first front sound cavity 511 is formed between the first speaker 510 and the middle plate 230 through a sealing structure, and is connected to the first sound outlet 222; the side of the diaphragm of the first speaker 510 facing the display module 100 is the rear side, and the second cavity 710 and the first cavity 721 form the first rear sound cavity 512 of the first speaker 510. Since the remaining structures are the same as those in the above embodiment, they are not described repeatedly.

[0102] The above embodiment is described by taking the second cavity 710 being disposed between the display module 100 and the middle plate 230, and the first cavity 720 being disposed between the middle plate 230 and the back cover 210 as an example. Fig.11 , Fig.11 This is a cross-sectional view of another electronic device 10 provided in an embodiment of the present application. The second cavity 710 may be disposed between the back cover 210 and the middle plate 230 , and the first cavity 720 may be disposed between the display module 100 and the middle plate 230 .

[0103] For details, please continue to see Fig.11 The battery 600 is arranged between the back cover 210 and the middle plate 230, that is, the battery 600 is arranged in the second cavity 710, and the accommodating groove 231 is arranged on the surface of the middle plate 230 facing the back cover 210; the first speaker 510, the main circuit board 300, the second speaker 520 and the auxiliary circuit board 400 are all arranged between the display module 100 and the middle plate 230, that is, in the first cavity 720, and the first groove 232 and the second groove 233 are both arranged on the surface of the middle plate 230 facing the display module 100.

[0104] To make the rear sound chambers of the first speaker 510 and the second speaker 520 both open sound chambers, please continue to refer to Fig.11 The isolation part 800 is also disposed between the middle plate 230 and the display module 100, that is, in the first cavity 720, so that the first cavity 720 is separated into a first cavity 721 and a second cavity 722 which are independent of each other. In this way, the first cavity 721 and the second cavity 710 (the first cavity 721 and the second cavity 710 are connected through the connection notch 236 on the middle plate 230) form the first rear sound cavity 512 of the first speaker 510, and the second cavity 722 forms the second rear sound cavity 522 of the second speaker 520.

[0105] In addition, the first speaker 510 and the second speaker 520 are both fixed on the middle plate 230 through a sealing structure; the space between the first speaker 510 and the middle plate 230 is the first front sound cavity 511, and is connected to the first sound outlet hole 222 at the top of the frame 220; the space between the second speaker 520 and the middle plate 230 is the second front sound cavity 521, and is connected to the second sound outlet hole 223 at the bottom of the frame 220.

[0106] It should be noted that when the electronic devices in the second cavity 710 fill the second cavity 710 completely, or the middle plate 230 and the back cover 210 are completely attached, that is, there is no cavity in the second cavity 710. In this case, the first rear sound cavity of the first speaker 510 can be formed only by the first cavity 721 (at this time, the first cavity 721 is located between the middle plate 230 and the display module 100), and the second rear sound cavity 522 of the second speaker 520 can be formed by the second cavity 722.

[0107] In this example, see Fig.12 , Fig.12 A cross-sectional view of another electronic device 10 provided in an embodiment of the present application, the first speaker 510 and the main circuit board 300 can also be arranged in the second cavity 710, that is, the first speaker 510, the main circuit board 300 and the battery 600 are all arranged between the back cover 210 and the middle plate 230. At this time, the first groove 232 and the receiving groove 231 are both arranged on the surface of the middle plate 230 facing the back cover 210. The space between the first speaker 510, the middle plate 230 and the sealing structure forms the first front sound cavity 511 of the first speaker 510, and is connected to the first sound outlet 222. The second cavity 710 and the first chamber 721 form the first rear sound cavity 512 of the first speaker 510. The structure of the second speaker 520 is the same as that of the above embodiment, so it will not be described repeatedly.

[0108] Based on this, in the electronic device 10 provided in the embodiment of the present application, the second speaker 520 and the battery 600 are respectively arranged on both sides of the middle plate 230, that is, the battery 600 is arranged in the second cavity 710, and the second speaker 520 is arranged in the first cavity 720. In addition, the first cavity 720 is separated into a first cavity 721 and a second cavity 722 which are independent of each other and not connected to each other by the isolation part 800, the second speaker 520 is arranged in the second cavity 722, the first cavity 721 and the second cavity 710 are connected to each other, and the first speaker 510 can be arranged in the first cavity 721 or the second cavity 710.

[0109] In this way, the second chamber 722 can form the second rear sound chamber 522 of the second speaker 520, and the first chamber 721 and the second chamber 710 form the first rear sound chamber 512 of the first speaker 510. Since the first chamber 721 and the second chamber 722 are independent of each other and do not communicate with each other, the first rear sound chamber 512 and the second rear sound chamber 522 are independent of each other and do not communicate with each other, so that the sound waves generated by the first speaker 510 and the sound waves generated by the second speaker 520 will not interfere with each other. In addition, since the first rear sound chamber 512 and the second rear sound chamber 522 are both open sound chambers, it is not necessary to set other first structural members inside the housing 200 of the electronic device 10 to form a closed sound chamber, which is conducive to saving space and making the electronic device 10 thinner and lighter.

[0110] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0111] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
