Description

TECHNICAL FIELD

[0001] The utility model relates to electronic equipment field especially a loudspeaker sound hole structure and electronic equipment. BACKGROUND

[0002] In the development course of electronic equipment, miniaturization and multifunctionalization have become the remarkable trend, which makes the design of each component inside the equipment face extremely severe challenges, especially the loudspeaker sound hole structure, the design of which is directly related to the audio performance and service life of the equipment.

[0003] At present, in the design process of the loudspeaker sound hole, in order to ensure that the sealing foam has enough pasting area and meet the detection process (such as CCD equipment detection) requirement after the foam is attached (specifically, the CCD equipment detection usually determines the inner side edge and the outer side edge of the shell end face with the sound passage as the inner circle reference line and the outer circle reference line respectively, and then carries out image recognition to compare the actual edge of the foam with the reference line, so as to judge whether the foam is pasted accurately), it is necessary to occupy part of the height space of the sound hole, which leads to that after the installation of the dust screen is completed, the intercepted range is relatively limited, and the sound outlet is easily blocked by the dust screen and cannot sound.

[0004] In order to solve the above technical problem, the height of the sound hole is usually increased to increase the effective interception area of the dust screen, so as to reduce the risk of blocking the loudspeaker sound hole and prolong the service life of the product. In the prior art, the conventional method of increasing the height of the sound hole mainly includes reducing the thickness of the equipment shell and increasing the volume of the whole equipment, but the above two methods have certain defects: reducing the thickness of the equipment shell will affect the overall structural stability of the electronic equipment and the safety of the internal components, and increasing the volume of the equipment cannot meet the demand of miniaturization of the electronic equipment.

[0005] Therefore, a loudspeaker sound hole structure and electronic equipment are needed to solve the above problems. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing a loudspeaker sound hole structure and electronic equipment, which can improve the effective interception area of the dust screen, reduce the risk of blocking the loudspeaker sound hole and prolong the service life of the product without affecting the structural strength and volume and meeting the detection process requirement after the foam is attached.

[0007] In order to solve the above technical problem, the utility model provides a loudspeaker sound hole structure, which comprises a shell with a sound passage, a dust positioning assembly and a boss.

[0008] One end of the shell has a foam bonding surface.

[0009] The dustproof positioning assembly comprises a dustproof net and a foam piece which are sequentially attached to the foam bonding surface.

[0010] The boss is arranged on the upper and lower surfaces of the shell.

[0011] The side of the two bosses away from the shell serves as an outer circle reference line to which the foam piece is attached.

[0012] Further, the vertical distance between the side of the boss away from the shell and the shell is 0.14mm-0.16mm.

[0013] Further, the boss is arranged in a long strip structure and has a length of 1.4mm-1.5mm.

[0014] Further, the boss and the end of the shell are located in the same vertical plane.

[0015] Further, the width of the foam piece is smaller than the width of the foam bonding surface.

[0016] Further, the width of the foam piece is 0.74mm-0.76mm.

[0017] In another aspect, an electronic device is also provided, which comprises an electronic device body and the loudspeaker sound hole structure as described in the above embodiments.

[0018] The loudspeaker sound hole structure is arranged in the electronic device body.

[0019] The electronic device body is internally formed with an avoiding area for avoiding the boss.

[0020] Further, the electronic device body comprises a middle frame with an antenna circuit board and a front shell.

[0021] The antenna circuit board and the front shell are surrounded by a cavity which wraps the end of the shell.

[0022] The avoiding area is arranged on the antenna circuit board and the front shell.

[0023] Further, the middle frame and the front shell are both provided with a sound outlet which communicates with the sound passage.

[0024] Further, the electronic device body is any one of a mobile phone, a tablet computer and a wearable electronic device.

[0025] Compared with the prior art, the utility model has at least the following beneficial effects:

[0026] By setting the boss on the upper and lower surfaces of the shell, and taking the side of the boss away from the shell as the outer circle reference line of the foam piece, the traditional CCD device is changed from the way of taking the outer edge of the foam bonding surface as the outer circle reference line, so that the two sides of the foam piece can be stretched outward by a certain distance for pasting. Since the foam piece is made of flexible material, the middle area of the foam piece will be deformed and enlarged after stretching. Therefore, when the same specification foam piece is attached, the space occupied by the foam piece in the sound outlet channel height space can be effectively reduced, so as to increase the coverage area of the dust screen without increasing the product volume, thereby improving the effective interception area of the dust screen, reducing the risk of dust blocking the sound hole, and prolonging the service life of the product.

[0027] Furthermore, by the above-mentioned manner, the foam piece can still be detected by the CCD device after being attached, so as to meet the process detection requirement after the foam piece is attached.

[0028] Further, by setting the avoidance area of the avoidance boss in the electronic device body, it is ensured that the loudspeaker sound hole structure can be normally assembled into the electronic device body, and the strength of the overall electronic device body is not affected.

It should be noted that the drawings are very simplified and use non-precise proportions, only to facilitate and clarify the purpose of assisting the description of the embodiment of the present application.

[0034] Embodiment one

[0035] As Figure 1 And Figure 2 The utility model discimented provides a loudspeaker sound hole structure, including the shell 1 with the sound passage 11, dustproof positioning assembly 2 and boss 3.

[0036] One end of the shell 1 has a foam bonding surface 12 for mounting the dustproof positioning assembly 2.

[0037] Specifically, the dustproof positioning assembly 2 includes a dust screen 21 and a foam piece 22 that are sequentially attached to the foam bonding surface 12. The dust screen 21 intercepts external dust, and the foam piece 22 provides secondary sealing to prevent dust from entering the shell 1.

[0038] In this embodiment, the boss 3 is arranged on the upper and lower surfaces of the shell 1 and serves as a positioning reference for attaching the foam piece 22.

[0039] Specifically, the two bosses 3 away from one side of the shell 1 serve as the outer circle reference line for attaching the foam piece 22.

[0040] The device changes the traditional CCD device method of using the outer edge of the foam bonding surface 12 as the outer circle reference line by arranging the boss 3 on the upper and lower surfaces of the shell 1 and using the side of the boss 3 away from the shell 1 as the outer circle reference line for attaching the foam piece 22. This allows the foam piece 22 to stretch outward by a certain distance on both sides for attachment. Since the foam piece 22 is made of flexible material, the middle region of the foam piece 22 will deform and increase in size after stretching. This effectively reduces the space occupied by the foam piece 22 in the height space of the sound passage 11 when using the same size foam piece 22 for attachment. This increases the coverage area of the dust screen 21 without increasing the product size, improves the effective interception area of the dust screen 21, reduces the risk of dust blocking the sound hole, and prolongs the service life of the product.

[0041] Furthermore, the foam piece 22 can still be detected by the CCD device after attachment, meeting the process detection requirements of the attached foam piece 22.

[0042] In this embodiment, the size of the boss 3 is further limited so that it does not have a significant impact on the internal structure of the electronic device body 4 when installed on the electronic device body 4. Specifically, the vertical distance between the side of the boss 3 away from the shell 1 and the shell 1 is 0.14mm-0.16mm, and preferably 0.15mm.

[0043] In one specific example, the boss 3 is provided as a long strip protruding structure, and the length is 1.4mm-1.5mm.

[0044] In order to facilitate the identification of the outer ring reference line by the CCD device, the boss 3 and the end of the shell 1 are arranged in the same vertical plane, so that the foam piece 22 can be better detected after being attached.

[0045] It should be noted that the width of the foam piece 22 is smaller than the width of the foam bonding surface 12, so as to reserve a certain gap to facilitate attachment and improve the accuracy of attachment positioning.

[0046] In this embodiment, the width of the foam piece 22 is 0.74mm-0.76mm, preferably, the width of the foam piece 22 is 0.75mm, which further improves the effective interception area of the dust screen 21 under the premise of meeting the sealing performance.

[0047] Embodiment two

[0048] As shown in Figure 2 This embodiment two further proposes an electronic device based on the embodiment one, which comprises an electronic device body 4 and the loudspeaker sound hole structure as described in the embodiment one.

[0049] The loudspeaker sound hole structure is arranged in the electronic device body 4.

[0050] In addition, the electronic device body 4 is internally formed with an avoiding area 5 for avoiding the boss 3.

[0051] By arranging the avoiding area 5 for avoiding the boss 3 in the electronic device body 4, it is ensured that the loudspeaker sound hole structure can be normally assembled into the electronic device body 4, and the strength of the whole electronic device body 4 is not affected.

[0052] In this embodiment, a specific electronic device body 4 is further proposed to further define the position of the avoiding area 5. Specifically, the electronic device body 4 comprises a middle frame 41 with an antenna circuit board 411 and a front shell 42.

[0053] The antenna circuit board 411 and the front shell 42 are surrounded to form a cavity wrapping the end of the shell 1.

[0054] The avoiding area 5 is arranged on the antenna circuit board 411 and the front shell 42, and because the length of the boss 3 is 1.4mm-1.5mm and the vertical height is 0.14mm-0.15mm, the performance of the antenna circuit board 411 and the front shell 42 is not affected, thereby the effective interception area of the dustproof net 21 can be improved, the risk of the loudspeaker sound hole being blocked can be reduced, the service life of the electronic equipment body 4 is prolonged, under the premise of not affecting the structural strength and volume and meeting the detection process requirement after the foam is attached.

[0055] In other embodiments, the middle frame 41 and the front shell 42 are both provided with a sound outlet 6 which is in communication with the sound outlet channel 11.

[0056] Among them, the electronic equipment body 4 is any one of a mobile phone, a tablet computer and a wearable electronic device.

[0057] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
