An electronic apparatus 50 according to an embodiment of the present invention is described below with reference to fig. 1 to 8.

As shown in fig. 1 and 2, according to an electronic device 50 according to some embodiments of the present invention, the electronic device 50 includes a screen support 10, a screen 40, a speaker unit 20, a speaker cover 30, and a sound-absorbing module 140, and a mounting gap 410 is formed between the screen 40 and the screen support 10. The speaker unit 20 is installed in the screen support 10, the speaker cover plate 30 is disposed on one side of the screen support 10 far away from the screen 40, the speaker cover plate 30, the speaker unit 20 and the screen support 10 jointly enclose to form a first space 310, the screen support 10 is provided with a through hole 110, the first space 310 is communicated with the installation gap 410 through the through hole 110, and the first space 310 and the installation gap 410 jointly form a rear sound cavity of the speaker unit 20. The sound-absorbing module 140 is disposed in the mounting gap 410, and the sound-absorbing module 140 can be used to reduce screen vibration.

The through hole 110 is formed in the screen bracket 10 to communicate the first space 310 with the mounting gap 410, so as to expand the rear sound cavity, thereby improving the sound quality of the speaker unit 20. Meanwhile, in order to avoid the screen vibration caused by the sound wave vibration of the installation gap 410, the sound absorption module 140 is arranged between the screen 40 and the screen support 10 to weaken the screen vibration, so that the volume of the rear sound cavity is enlarged under the condition that the normal use state of the screen 40 is not influenced, and the sound quality effect of the speaker unit 20 is further improved.

It should be noted that, in an alternative embodiment of the present invention, the volume of the installation gap 410 is also used as a part of the volume of the back sound cavity, so as to achieve the effect of expanding the volume of the back sound cavity, thereby improving the sound quality. For example, when dual speakers are used on the electronic device 50, the speakers are disposed on both the top and bottom of the electronic device 50. The top speaker is selected to connect the first space 310 with the mounting gap 410, so as to enlarge the volume of the rear sound cavity and improve the sound output effect of the electronic device 50, thereby improving the hearing enjoyment brought by the user experience stereo sound.

In some embodiments of the present invention, since the screen 40 is installed on the side of the screen support 10 opposite to the speaker unit 20, in order to avoid screen vibration caused by vibration generated when air waves enter the installation gap 410 through the through hole 110 due to the sound of the speaker unit 20, which may affect the stability of the functional area and the experience of the user when using the screen 40, the functional opening area 120 formed on the screen support 10 needs to be sealed. That is, the sealing unit 130 is provided for each of the functional opening regions 120 so as not to affect the use stability of the functional member provided at the functional opening region 120 and the use stability of the screen 40 by the sound emission of the speaker unit 20.

Referring to fig. 3 to fig. 7, specifically, corresponding to the screen holder 10, at least one functional opening area 120 is formed on the screen holder 10, and the functional opening area 120 includes, but is not limited to, a proactive opening 1220 and a fingerprint opening 1230. The sealing unit 130 is disposed at each of the proactive opening 1220 and the fingerprint opening 1230, and the sealing unit 130 is sealed between the screen supporter 10 and the screen 40. It should be noted that the front camera opening 1220 is an area of the front camera corresponding to an opening on the screen holder 10, and the fingerprint opening 1230 is an area of the fingerprint key corresponding to an opening on the screen holder 10. To the trompil of the leading camera of seting up on screen support 10, the leading camera needs the daylighting to shoot, and then needs the trompil so that external illumination can get into the leading camera on screen support 10. Similarly, the fingerprint key area needs to collect the fingerprint of the user, and the corresponding hole sites need to be opened on the screen support 10 for signal transmission. The positions of the front camera and the fingerprint key where the hole sites are formed on the screen support 10 can be determined according to the actual positions of the front camera and the fingerprint key, and are not limited herein as long as the front camera can complete lighting and the fingerprint key area can acquire fingerprint information of a user.

In some embodiments of the present invention, the sealing unit 130 is a PET gasket or a foam gasket. Specifically, because the PET material is polyester resin, and the sealing ring made of the PET material is not favorable for lighting, a foam sealing ring is preferably used for the front camera opening 1220 so as to prevent the sealing ring from influencing the normal lighting and photographing of the front camera. For other open hole regions, both a PET sealing ring and a foam sealing ring can be selected, and are not limited herein, the PET sealing ring and the foam sealing ring can be adhered to the outer peripheral side of the functional open hole region 120, and the specific connection mode can also be realized by adopting a buckle or a threaded fixing piece, and is not limited herein.

In some embodiments of the present invention, the area corresponding to the speaker unit 20 is a sound generating area 1210, and the air wave received in the installation gap 410 propagates to the periphery through the through hole 110, so as to avoid generating screen vibration during the propagation of the air wave, and therefore the sound absorbing module 140 needs to be disposed around the sealing unit 130 to absorb the air flow generated by the air wave, thereby achieving the effect of reducing the screen vibration.

For the sound-absorbing module 140, the sound-absorbing module 140 is a sound-absorbing foam. In some embodiments of the present invention, the number of the sound absorption modules 140 is plural, and the plural sound absorption modules 140 are coaxially disposed with the center of the through hole 110 as an axis. Further, the number of the sound-absorbing modules 140 is plural, and the sound-absorbing modules 140 are coaxially disposed with the center of the through hole 110 as an axis. That is, when the air wave enters the installation gap 410 along the through hole 110, the sound absorption modules 140 can weaken the air wave in a hierarchical manner, so as to prevent the air wave from vibrating in the installation gap 410 to cause screen vibration.

Referring to fig. 5 to 6, in particular, the sound absorption module 140 may include a plurality of first sound absorption modules 1410 disposed on the periphery of the through hole 110 and a second sound absorption module 1420 surrounding the proactive opening 1220 and the fingerprint opening 1230. That is, when the air wave propagates along the through hole 110 in the mounting gap 410, the plurality of first sound absorption modules 1410 may consume the air wave, reduce the air wave, and further alleviate the diffusion of the air wave, thereby weakening the screen vibration. Further, when the remaining airwave reaches the proactive opening 1220 and the fingerprint opening 1230, the second sound-absorbing module 1420 can be utilized to surround the proactive opening 1220 and the fingerprint opening 1230 respectively to further reduce the remaining airwave, so as to avoid influencing the operation stability of the front camera and the fingerprint key in the using process.

It should be noted that, referring to fig. 5, the first sound absorption module 1410 may include a first layer of sound absorption foam, and the thickness of each layer of sound absorption module 140 corresponds to the first thickness. That is, in the case of the first thickness of the sound absorption foam, two, three or four layers may be provided. Referring to fig. 6, in an alternative embodiment of the present invention, the first sound absorption module 1410 may also include a second number of sound absorption modules 140, the thickness of each layer of sound absorption module 140 corresponds to the second thickness, and two, three or four layers of sound absorption modules 140 may also be disposed under the condition of the second thickness.

In an alternative embodiment of the invention, the first thickness is smaller than the second thickness in case the first number of layers is larger than the second number of layers. The first sound absorption module 1410 may be provided with three sound absorption modules 140 having a first thickness, or may be provided with two sound absorption modules 140 having a second thickness. Here, the three and two layers are only used as examples, but not limited thereto, and in an alternative embodiment of the present invention, the first sound absorption module 1410 may be provided with two sound absorption modules 140 having the first thickness, or one sound absorption module 140 having the second thickness.

Further, the thickness of the sound-absorbing module 140 is proportional to the sound-absorbing effect. For the first sound absorption module 1410, the thicker the thickness of each sound absorption module 140 is, the better the sound absorption effect is, but at the same time, the mass of the electronic device 50 is increased. That is, the thickness of the sound-absorbing module 140 can be adjusted according to the space around the sound-emitting region 1210. For example, the sound-absorbing module 140 with a plurality of layers of the first thickness can be arranged in a larger space around the sound-emitting region 1210; if the space around the sound-emitting region 1210 is small, the sound-absorbing module 140 with the second thickness can be installed with a small number of layers. Taking the weight reduction of the electronic device 50 as a consideration, the sound-absorbing module 140 with multiple layers of the first thickness can be selected to reduce the screen vibration. And if the stability of taking a picture of the camera in the electronic device 50 and the accuracy of fingerprint key identification are taken into consideration, the sound-absorbing module 140 with multiple layers of the second thickness can be selected to reduce screen vibration. The thickness of the first sound absorption module 1410 can be adjusted according to the specific requirement of the actual electronic device 50, and is not limited herein.

In some embodiments of the present invention, the plurality of sound absorption modules 140 may be stacked in the installation gap 410, each sound absorption module 140 is provided with a hole corresponding to the through hole 110, and the holes in each sound absorption module 140 are coaxially arranged with the center of the through hole 110. Also can regard as the lamellar setting with inhaling sound module 140, and set up the hole site corresponding with through-hole 110, fingerprint trompil 1230 and proactive trompil 1220 on inhaling sound module 140, then range upon range of setting in order to weaken the intensity that gets into the air wave in installation clearance 410 through-hole 110, avoid the screen vibration and ensure the stability of leading camera and fingerprint button when using from this.

Further, the plurality of sound-absorbing modules 140 gradually increase in thickness in a direction away from the screen 40. For example, if the number of the sound-absorbing modules 140 is three, the thickness of the sound-absorbing module 140 is the smallest on the side close to the screen 40, and then the thickness of the sound-absorbing module 140 attached to the screen holder 10 is the largest on the middle sound-absorbing module 140. The air wave flowing through the through hole 110 into the mounting gap 410 flows not only in a lateral direction, i.e. flows to the fingerprint opening 1230 and the proactive opening 1220, but also in a longitudinal direction, e.g. flows to the screen 40 side, because the screen 40 side may affect the normal use state of the screen 40, the side far away from the screen 40 preferably reduces all the air waves, i.e. the thickness of the sound-absorbing module 140 near the screen support 10 side is set to be thicker, which is beneficial to silencing the air waves passing through the through hole 110, and then the effect of reducing screen vibration is achieved.

In some embodiments of the present invention, the number of the sound-absorbing modules 140 is two, one of the sound-absorbing modules 140 is disposed around the through hole 110, and the other is disposed around both the through hole 110 and the fingerprint opening 1230. It should be noted that, for the sound-absorbing module 140 disposed around the through hole 110, the sound-absorbing module 140 may be disposed in multiple layers and spaced apart from each other, and specifically, the arrangement of the first sound-absorbing module 1410 may be referred to, which is not limited herein.

In some embodiments of the present invention, the two sound absorption modules 140 are stacked in the mounting gap 410, and each sound absorption module 140 is provided with a hole corresponding to the through hole 110 and the fingerprint opening 1230, and the holes in each sound absorption module 140 are coaxially arranged with the through hole 110 as the center. Further, the number of the sound absorption modules 140 may be three, four, or the like, and the number is not limited herein. To improve the sound deadening effect, the thickness of the sound-absorbing module 140 may be increased in the direction away from the screen 40. Thus, when the air wave flows into the installation gap 410 through the through hole 110, the thicker sound absorption module 140 flows through first, and the air wave is further reduced in level, until the air wave reaches the side of the screen 40, so that the stability of the screen 40 in use is not affected.

In still other embodiments of the present invention, the number of the sound-absorbing modules 140 is three. One of the sound-absorbing modules 140 is disposed around the through hole 110, the other is disposed around the through hole 110 and the fingerprint opening 1230, and the other is disposed around the through hole 110, the fingerprint opening 1230 and the proactive opening 1220. That is, the sound is attenuated around the through hole 110, around the fingerprint opening 1230 and around the front camera 1220, so that the air wave entering the mounting gap 410 through the through hole 110 can be prevented from affecting the stability of the fingerprint key and the front camera.

Further, to inhaling the sound module 140, also can range upon range of and set up in installation clearance 410, and all offer the hole site that corresponds with through-hole 110, proactive trompil 1220 and fingerprint trompil 1230 on each inhaling the sound module 140, the hole site in each inhaling the sound module 140 uses the center of through-hole 110 as the axle, coaxial setting. To the sound module 140 of inhaling of range upon range of setting, along screen 40 to the direction of screen support 10, each thickness of inhaling sound module 140 increases progressively, and the air wave that gets into through-hole 110 like this can be earlier through the thick sound module 140 of inhaling of thickness and carry out the amortization, range upon range of amortization, is favorable to making the air wave can't arouse the screen vibration when being close to screen 40.

In some embodiments of the present invention, the functional opening area 120 further includes a screw opening 1240, and the screw opening 1240 is a hole created for mounting the screen bracket 10 or the like, and other hole locations than the screw opening 1240 are not exemplified herein.

Referring to fig. 1, for the screen holder 10, in some embodiments of the present invention, the first groove 150 and the second groove 160 are disposed at an interval along the length direction of the screen holder 10, so as to facilitate weight reduction of the screen holder 10 and installation of other components.

That is, the through-holes 110 are provided at one side of the speaker unit 20 and communicate with the first space 310 and the mounting gap 410, respectively. In alternative embodiments of the present invention, the number of the through holes 110 may also be multiple, for example, two, three, or four, and is not limited herein.
