[0068] The following detailed description will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION
[0069] In order to further clarify the technical means and effects taken by the present application to achieve the intended purpose of the application, the following will be described in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, not all.
[0070] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing the specific embodiments only and is not intended to be limiting of the application.
[0071] Some embodiments of the present application provide an electronic device, which includes a support and a speaker assembly. The support is provided with a first cavity. The speaker assembly includes a shell and a speaker body. The shell is arranged in the first cavity and is provided with a second cavity. The speaker body is arranged in the shell and divides the second cavity into a front cavity and a rear cavity. The shell is provided with a first through hole communicating the second cavity. An inner wall of the first cavity cooperates with the shell to cover one side of the first through hole away from the second cavity.
[0072] In the above electronic device, the first through hole, the front cavity and the rear cavity have an increased total volume by the first through hole communicating the second cavity, the inner wall of the first cavity of the support and the shell cooperating to cover one side of the first through hole away from the second cavity. This is conducive to increasing the volume of the rear cavity of the speaker body in the speaker assembly, thereby improving the audio effect of the speaker assembly and further providing the electronic device with better audio experience.
[0073] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.
[0074] Referring to FIG. 1, an embodiment of the present application provides an electronic device 100. The electronic device 100 has an audio playing function. In an embodiment, the electronic device 100 is a mobile phone, but is not limited thereto. For example, in other embodiments, the electronic device 100 can be a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc.
[0075] The electronic device 100 comprises a support 10, a speaker assembly 20 and a screen 40. The speaker assembly 20 is arranged in the support 10. The screen 40 is arranged at one side of the support 10. The screen 40 is used to display pictures. It can be understood that the screen 40 can also be omitted when the electronic device 100 does not have a display function.
[0076] Please refer to FIG. 2 and FIG. 3. FIG. 2 is a perspective view of the electronic device 100 omitting the screen 40 according to some embodiments provided in the present application. FIG. 3 is a plan view of the electronic device 100 shown in FIG. 2. The support 10 is provided with a first cavity 101. The speaker assembly 20 is arranged in the first cavity 101. The speaker assembly 20 comprises a housing 21 and a speaker body 23. The speaker body 23 is a structure for converting an audio electrical signal into a sound signal.
[0077] The housing 21 is provided with a second cavity 201. The speaker body 23 is arranged in the second cavity 201 and divides the second cavity 201 into a front cavity 2011 and a rear cavity 2013. The front cavity 2011 is in communication with an external environment outside the electronic device 100. When the speaker body 23 works, it can push the air in the front cavity 2011 to vibrate and emit sound, which is transmitted to the outside of the electronic device 100.
[0078] The housing 21 is provided with a first through hole 203. The first through hole 203 is in communication with the rear cavity 2013 of the second cavity 201. The inner wall of the first cavity 101 in the support 10 cooperates with the housing 21 to cover and seal one side of the first through hole 203 away from the rear cavity 2013, so that the first through hole 203 and the rear cavity 2013 form a closed space. The space formed by the communication between the first through hole 203 and the rear cavity 2013 serves as a rear sound cavity of the speaker body 23. The volume of the rear sound cavity is larger than that of the rear cavity 2013, which improves the audio effect, such as low frequency effect, of the speaker assembly 20, thereby bringing a better audio experience to the electronic device 100.
[0079] In an embodiment, the electronic device 100 is substantially rectangular and flat, but is not limited thereto.
[0080] For the convenience of the following description, a rectangular coordinate system is established for the electronic device 100 shown in FIG. 1. The thickness direction Z of the electronic device 100 is defined as the stacking direction of the screen 40 and the support 10. The directions perpendicular to the thickness direction Z are the length direction X and the width direction Y of the electronic device 100, and the length direction X and the width direction Y are perpendicular. It can be understood that the coordinate system of the electronic device 100 can be flexibly set according to actual needs, which is not specifically limited herein.
[0081] In an embodiment, the front cavity 2011, the speaker body 23 and the rear cavity 2013 are arranged along the thickness direction Z, but are not limited thereto. For example, in other embodiments, when the thickness of the speaker body 23 along the thickness direction Z is reduced, the front cavity 2011, the speaker body 23 and the rear cavity 2013 can also be arranged along the width direction Y or the length direction X.
[0082] The volume of the first cavity 101 in the electronic device 100 does not need to be changed, the layout of the elements in the first cavity 101 does not need to be changed, and the size of the shell 21 of the speaker assembly 20 does not need to be changed, so that the volume of the rear sound cavity of the speaker body 23 can be increased by opening a hole (the first through hole 203) on the shell 21 or opening a hole (the second through hole 301) on the first sealing member 30.
[0083] Please refer to FIG. 4 and FIG. 5, FIG. 4 is a schematic diagram of the speaker assembly 20 without the first through hole 203 in the shell 21, and FIG. 4 shows that the speaker assembly 20 is a one-piece speaker structure, and the speaker assembly 20 forms independent front and rear cavities 2011 and 2013 in the shell 21.
[0084] FIG. 5 is a schematic diagram of the speaker assembly 20 with the first through hole 203 in the shell 21, and the number of the first through hole 203 is two; the two first through holes 203 are of the same volume and are arranged side by side at intervals, and a connecting arm 211 is formed between the two first through holes 203; the cross section of the first through hole 203 is substantially rectangular, but is not limited thereto. The connecting arm 211 of the shell 21 between the two first through holes 203 is connected to the inner wall of the first cavity 101 of the support 10; under the premise of the same volume, compared with the case where the number of the first through hole 203 is one, the interval arrangement of the two first through holes 203 can improve the strength of the shell 21 connected to the inner wall of the first cavity 101, so that the inner wall of the first cavity 101 is supported at the middle position of the plurality of first through holes 203, thereby improving the ability of the support 10 to resist deformation when subjected to external force.
[0085] It can be understood that in other embodiments, the number of the first through holes 203 can also be one, three, or other numbers. The cross-sectional shape of the first through holes 203 can also be circular or other shapes. The layout of the plurality of first through holes 203 can also adopt other arrangements. For example, in another embodiment, as shown in FIG. 6, the number of the first through holes 203a is four, the volumes of the four first through holes 203a are different, and the cross-sectional shape of the first through holes 203a is triangular; the four first through holes 203a are arranged in a circumferential direction to form two diagonally connected connecting arms 211a, and the two connecting arms 211a are cross-connected to the support 10, further increasing the area of the part of the shell 21 between the plurality of first through holes 203 connected to the support 10, and increasing the distribution density of the connecting arms 211a, and further improving the ability of the support 10 to resist deformation under external force. In still another embodiment, as shown in FIG. 7, the number of the first through holes 203b is four, the shape of the first through holes 203b is substantially rectangular, the four first through holes 203b are arrayed and form two cross-shaped connecting arms 211b, and the two connecting arms 211b are respectively connected to the support 10.
[0086] Referring to FIGS. 2 and 3, in an embodiment, the support 10 includes a support body 11 and a cover 13. The support body 11 is connected with the cover 13 and surrounds to form the first cavity 101. The screen 40 is connected to the support body 11 and is located on opposite sides of the support body 11 with the cover 13, respectively.
[0087] In an embodiment, the rear cavity 2013 in the second cavity 201 is closer to the cover 13 than the front cavity 2011. The first through holes 203 are arranged on the side of the shell 21 facing the cover 13, so as to facilitate the connection and cooperation of the shell 21 and the cover 13, and make the cover 13 close the side of the first through holes 203 away from the rear cavity 2013.
[0088] The electronic device 100 further includes a first sealing member 30. The first sealing member 30 is connected between the inner wall of the first cavity 101 and the shell 21. Further, the first sealing member 30 is connected between the shell 21 and the cover 13. The first sealing member 30 can be foam or adhesive-backed. The first sealing member 30 is connected between the cover 13 and the shell 21 by being adhered to the cavity wall of the first cavity 101 and the shell 21, respectively. The first sealing member 30 is provided with a second through hole 301. The second through hole 301 communicates with the first through hole 203, so that the second through hole 301 also serves as part of the rear sound cavity of the loudspeaker body 23, further increases the volume of the rear sound cavity, and further improves the audio effect of the loudspeaker assembly 20.
[0089] The cover 13 is substantially in a sheet shape. The space between the support body 11 and the cover 13 forms a first cavity 101, in which components such as a battery, a circuit board and the like are arranged. The support body 11 is provided with a groove 103, and the groove wall of the groove 103 and the shell 21 form the first cavity 101. The first cavity 101 can be a closed, open or semi-open cavity structure. The first seal 30 is sealingly connected between the cover 13 and the shell 21, and the second through hole 301 communicates with the first through hole 203, so that the first seal 30 seals the side of the first through hole 203 away from the rear cavity 2013 of the second cavity 201, and the closed nature of the first cavity 101 does not affect the closed nature of the rear cavity 2013 of the second cavity 201.
[0090] In an embodiment, the orthographic projection of the first through hole 203 on the cover 13 is within the orthographic projection of the second through hole 301 on the cover 13, but is not limited thereto. For example, in another embodiment, as shown in FIG. 8, the orthographic projections of the first through hole 203 and the second through hole 301a of the seal 30a on the cover 13 of the support 10 coincide, so that the connection area of the shell 21 and the support 10, and the volume of the first through hole 203 and the second through hole 301a as the rear sound cavity of the speaker body 23 are adapted, so as to achieve the effect of ensuring the connection strength of the shell 21 and the support 10 while improving the volume of the rear sound cavity of the speaker body 23.
[0091] The cover 13 is made of glass or ceramic, which has a higher hardness than metal and plastic, so as to solve the problem that the support 10 exposed outside the electronic device 100 is directly covered by the cover 13 and communicates with the side of the second cavity 201, and the cover 13 vibrates obviously when the speaker body 23 works.
[0092] In yet another embodiment, please refer to FIG. 9. The difference between the electronic device 100a shown in FIG. 9 and the electronic device 100 shown in FIG. 2 is that another first through hole 203d and a first seal 30b are added. The first through hole 203d is arranged on the side of the shell 21d away from the cover 13. The first through hole 203d communicates with the front cavity 2011 of the second cavity 201. The first seal 30b is connected between the shell 21d and the support body 11 of the support 10. The first seal 30b and the support body 11 seal the side of the first through hole 203d away from the second cavity 201. The first through hole 203d communicates with the front cavity 2011, so that the space formed by the first through hole 203d and the front cavity 2011 serves as the front sound cavity of the speaker body 23. The first through hole 203d increases the volume of the front sound cavity, and the volume of the front sound cavity is a set value, which can be the volume of the front cavity 2011 when the first through hole 203d is arranged. Therefore, reducing the volume of the front sound cavity to the set value can increase the volume of the rear cavity 2013.
[0093] The first through hole 203d is in communication with the front cavity 2011, and the total volume of the first through hole 203d, the front cavity 2011 and the rear cavity 2013 can be increased. By adjusting the position of the loudspeaker body 23, the volume of the front cavity 2011 is reduced to the total volume of the first through hole 203d and the front cavity 2011 to reach a set value, so as to improve the volume of the rear cavity of the loudspeaker body 23 in the loudspeaker assembly 20, improve the audio effect of the loudspeaker assembly 20, and thus bring better audio experience to the electronic device 100a.
[0094] The loudspeaker body 23 can move in the second cavity 201 along the thickness direction Z, specifically, the loudspeaker body 23 moves along the thickness direction Z away from the cover 13, so as to achieve the volume of the first through hole 203d and the front cavity 2011 reaching a set value, and increase the volume of the rear cavity 2013.
[0095] It can be understood that in other embodiments, the first sealing member 30b can also be provided with a second through hole (not shown in the figure) to further increase the volume of the rear cavity of the loudspeaker body 23.
[0096] It can be understood that in other embodiments, the electronic device 100a shown in FIG. 9 can also omit the first through hole 203.
[0097] Therefore, the first through hole 203d is in communication with the front cavity 2011 or the rear cavity 2013 of the second cavity 201, and the inner wall of the first cavity 101 in the support 10 and the shell 21c cooperate to cover and seal the side of the first through hole 203d away from the second cavity 201, so as to increase the total volume of the first through hole 203d, the front cavity 2011 and the rear cavity 2013, and facilitate the increase of the volume of the rear cavity of the loudspeaker body 23 in the loudspeaker assembly 20, so as to improve the audio effect of the loudspeaker assembly 20, and thus bring better audio experience to the electronic device 100.
[0098] Please refer to FIG. 3, the support body 11 is provided with a third through hole 105. The third through hole 105 is in communication with the first cavity 101 and the outside of the support 10. The shell 21 is provided with a fourth through hole 205. The fourth through hole 205 penetrates the shell 21, so that the front cavity 2011 is in communication with the outside of the shell 21 through the fourth through hole 205. The third through hole 105 and the fourth through hole 205 are in communication to form a sound conduction channel, which is in communication with the front cavity 2011 and the outside of the electronic device 100, and thus realizes the sound conduction to the outside of the electronic device 100.
[0099] In an embodiment, the electronic device 100 further comprises a protective net 50. The protective net 50 is arranged between the third through hole 105 and the fourth through hole 205. The protective net 50 can prevent impurities such as dust and particles from entering the loudspeaker assembly 20.
[0100] In an embodiment, the electronic device 100 further comprises a second sealing member 60. The second sealing member 60 is substantially annular. The second sealing member 60 is connected between the support body 11 and the housing 21, and surrounds the third through hole 105 and the fourth through hole 205, thereby preventing impurities such as dust and particles from entering the first cavity 101 through the fourth through hole 205.
[0101] Referring to FIGS. 10 to 13, FIGS. 10 and 13 illustrate an electronic device 100c according to another embodiment of the present application. The electronic device 100c shown in FIG. 10 is different from the electronic device 100c shown in FIG. 2 in that the speaker assembly 20 is a semi-sealed structure, and the structure of the support body 11c is changed with respect to the speaker adaptability. Specifically, the cover 13 is disposed on the support body 11c and forms the first cavity 101. The front cavity 2011c in the speaker assembly 20 is closer to the cover 13 than the rear cavity 2013c.
