Technical Field

[0001] This invention relates to the field of mobile phone accessories technology, specifically to a mobile phone speaker housing that can prevent deformation. Background Technology

[0002] Mobile phones are one of the most important communication tools for modern people, enabling real-time calls. The speaker is a crucial component ensuring clear sound from the phone. To improve sound quality and meet user needs, people are paying increasing attention to speakers, and consequently, the requirements for speaker casings are becoming more stringent. However, the following problems still exist with current mobile phone speaker casings on the market:

[0003] 1. Existing mobile phone speaker casings do not have the function of preventing casing deformation. During long-term use, the speaker may be damaged due to casing deformation.

[0004] 2. Conventional mobile phone speaker casings are prone to vibration during use, which can cause tremors and affect the sound quality of the speaker.

[0005] 3. Conventional mobile phone speaker casings are not easy to disassemble and reinstall stably when the casing is damaged.

[0006] To address the aforementioned issues, an innovative design was developed based on the existing mobile phone speaker casing. Summary of the Invention

[0007] The purpose of this invention is to provide a mobile phone speaker housing that can prevent deformation, in order to solve the problems mentioned in the background art. Currently common mobile phone speaker housings on the market do not have the function of preventing deformation of the housing. During long-term use, the speaker may be damaged due to deformation of the housing. In addition, the speaker is prone to vibration during use, which can cause vibrating sound and affect the sound quality of the speaker. Furthermore, it is not convenient to quickly disassemble and stably install the housing when it is damaged.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a mobile phone speaker shell that can prevent deformation, comprising a shell body, a limiting hole being opened inside the top of the shell body, a fixing edge being provided on the outer side of the upper end of the shell body, a protective layer being connected to the inner side of the shell body, and a sealing cover being installed on the top of the shell body, fastening bolts being installed on both the left and right ends of the sealing cover, and a positioning pin being provided on one side of the fastening bolts, and a pressing mechanism being installed on the lower surface of the sealing cover;

[0009] A pressing plate is provided on the right side of the pressing mechanism, and a connecting plate is installed above the pressing plate. A sound-permeable hole is opened in the lower left interior of the outer shell body, and support frames are installed at both the front and rear ends of the outer shell body. A base plate is bolted to the bottom of the support frame.

[0010] Preferably, the outer shell body includes a wear-resistant layer, an isolation layer, an anti-corrosion layer, and a positioning rod, and the wear-resistant layer, the isolation layer, and the anti-corrosion layer are arranged sequentially from front to back, and the interior of the wear-resistant layer, the isolation layer, and the anti-corrosion layer is provided with holes that match the positioning rod.

[0011] Preferably, the isolation layer includes a shielding layer, a heat-resistant layer, a reinforcing layer, and a crack-resistant layer, and the thicknesses of the shielding layer, the heat-resistant layer, the reinforcing layer, and the crack-resistant layer are all equal, and the connection method between each pair of the shielding layer, the heat-resistant layer, the reinforcing layer, and the crack-resistant layer is adhesive bonding.

[0012] Preferably, the fixed edge is symmetrically arranged about the central axis of the outer shell body, and the fixed edge is fixedly connected to the outer shell body to form an integrated structure, and the fixed edge is provided with screw holes inside.

[0013] Preferably, the protective layer is connected to the outer shell by adhesive bonding, and the protective layer is made of rubber elastic material. The lower left interior of the protective layer has a circular hole structure corresponding to the sound transmission hole, and the diameter of the circular hole structure is equal to the diameter of the sound transmission hole.

[0014] Preferably, the connection between the sealing cover and the positioning pin is welding, and the positioning pin is set in a one-to-one correspondence with the limiting hole.

[0015] Preferably, the clamping mechanism includes an adhesive, and a connecting pad is connected below the adhesive. A connecting folded tube is installed at the bottom of the connecting pad, and the connecting pad has a cavity structure inside, and the interior of the connecting pad and the interior of the connecting folded tube are interconnected.

[0016] Preferably, there are two sets of connecting folded tubes arranged symmetrically about the central axis of the connecting pad, and each set of connecting folded tubes has three tubes arranged at equal intervals. The adhesive is applied to the front and rear ends of the connecting pad.

[0017] Preferably, the thickness of the extrusion plate increases sequentially from left to right, and the extrusion plate is connected to the connecting plate by welding, the connecting plate is connected to the sealing cover by sliding connection, and a rectangular guide groove is provided inside the sealing cover.

[0018] Preferably, the longitudinal section of the support frame is arranged in an arc shape, and the support frame is connected to the outer shell body by bolts. The bottom end of the outer shell body has equally spaced openings, a fixing block is installed on the inner side of the opening, and an elastic plastic sheet is provided below the fixing block.

[0019] Compared with the prior art, the beneficial effect of the present invention is that the mobile phone speaker shell can prevent deformation.

[0020] 1. By setting up a wear-resistant layer, an isolation layer, and a reinforcing layer, the wear-resistant layer made of ceramic material and the reinforcing layer with woven metal wire inside can effectively improve the wear resistance and strength of the shell body, and can prevent the shell from deforming during long-term use.

[0021] 2. By setting up a clamping mechanism and an extrusion plate, during the speaker assembly process, the extrusion plate can be controlled to move to the left through the rectangular guide grooves opened inside the connecting plate and the sealing cover. Since the thickness of the extrusion plate increases from left to right, it can squeeze the connecting pad with the cavity structure inside during its leftward movement. Under the action of gas flow, the connecting folding tube in the contracted state can be extended and opened, and the gap between the speaker and the sealing cover can be filled, which can prevent the speaker from vibrating during use and causing vibrato, thus affecting the sound quality of the speaker.

[0022] 3. By setting up a support frame, fixing blocks, and elastic plastic sheets, the support frame with its arc-shaped structure can provide more effective support for the outer shell. When the outer shell is disassembled and replaced with the base plate, the elastic plastic sheet can be stretched into a "Y" shape under the squeezing action of the fixing blocks with a triangular cross-section during the insertion of the elastic plastic sheet into the opening. This facilitates the quick splicing and installation of the outer shell on the base plate and ensures high connection stability. Attached Figure Description

[0038] Please see Figure 1 , Figure 3 and Figure 4 This invention provides a technical solution: a mobile phone speaker shell capable of preventing deformation, comprising a shell body 1. To enable the shell body 1 to prevent deformation, a limiting hole 2 can be formed inside the top of the shell body 1. The shell body 1 includes a wear-resistant layer 101, an isolation layer 102, an anti-corrosion layer 103, and a positioning rod 104, and the wear-resistant layer 101, the isolation layer 102, and the anti-corrosion layer 103 are arranged sequentially from front to back. Both the 2 and anti-corrosion layers 103 have holes that match the positioning rod 104. The isolation layer 102 includes a shielding layer 1021, a heat-resistant layer 1022, a reinforcing layer 1023, and a crack-resistant layer 1024. The thicknesses of the shielding layer 1021, heat-resistant layer 1022, reinforcing layer 1023, and crack-resistant layer 1024 are all equal, and the connection between each pair of the shielding layer 1021, heat-resistant layer 1022, reinforcing layer 1023, and crack-resistant layer 1024 is an adhesive connection. A fixed edge 3 is provided on the upper outer side of the shell body 1. The fixed edge 3 is symmetrically arranged about the central axis of the shell body 1 and is fixedly connected to the shell body 1 in an integrated structure. A screw hole 4 is provided inside the fixed edge 3. A protective layer 5 is connected to the inner side of the shell body 1. A sealing cover 6 is installed on the top of the shell body 1. Fastening bolts 7 are installed on both the left and right ends of the sealing cover 6. A positioning pin 8 is provided on one side of the fastening bolt 7. The protective layer 5 is connected to the shell body 1 by adhesive bonding. The protective layer 5 is made of rubber elastic material. A circular hole structure corresponding to the sound transmission hole 12 is provided in the lower left of the protective layer 5. The diameter of the circular hole structure is equal to the diameter of the sound transmission hole 12. With the help of the wear-resistant ceramic layer 101 and the reinforcing layer 1023 with braided metal wire inside, the wear resistance and strength of the shell body 1 can be improved, and the shell deformation can be prevented.

[0039] Please see Figure 1 , Figure 2 , Figure 7 , Figure 8and Figure 9 To prevent the speaker from vibrating during use, a clamping mechanism 9 is installed on the lower surface of the sealed cover 6. The clamping mechanism 9 includes an adhesive 901, and a connecting pad 902 is connected below the adhesive 901. A connecting folded tube 903 is installed at the bottom of the connecting pad 902, and the connecting pad 902 has a cavity structure inside. The interior of the connecting pad 902 is interconnected with the interior of the connecting folded tube 903. Two sets of connecting folded tubes 903 are symmetrically arranged about the central axis of the connecting pad 902, and three connecting folded tubes 903 are evenly spaced in each set. The adhesive 901 is applied to the upper part of both ends of the connecting pad 902. A pressing plate 1 is provided on the right side of the clamping mechanism 9. The thickness of the extrusion plate 10 increases sequentially from left to right. The extrusion plate 10 is connected to the connecting plate 11 by welding, and the connecting plate 11 is connected to the sealing cover 6 by sliding connection. A rectangular guide groove is provided inside the sealing cover 6. The connecting plate 11 is installed above the extrusion plate 10. A sound-permeable hole 12 is provided inside the lower left of the outer shell body 1. By controlling the extrusion plate 10 to move to the left, the connecting pad 902 with a cavity structure inside can be squeezed. Under the action of gas flow, the connecting folding tube 903 in the contracted state can be extended and opened, and the gap between the speaker and the sealing cover 6 can be filled. This can prevent the speaker from vibrating during use and causing vibrato, thus affecting the sound quality of the speaker.

[0040] Please see Figure 5 and Figure 6 In order to facilitate the replacement and stable installation of the outer shell body 1, support frames 13 can be installed at both the front and rear ends of the outer shell body 1. A base plate 14 is bolted to the bottom of the support frame 13. The longitudinal section of the support frame 13 is set with an arc-shaped structure, and the support frame 13 is connected to the outer shell body 1 by bolts. The bottom end of the outer shell body 1 has equally spaced openings 15. A fixing block 16 is installed on the inner side of the opening 15, and an elastic plastic sheet 17 is set below the fixing block 16. When the elastic plastic sheet 17 is inserted into the opening 15, under the squeezing action of the fixing block 16 with a triangular longitudinal section, the elastic plastic sheet 17 can be stretched into a "Y" shape, which facilitates the quick splicing and installation of the outer shell body 1 on the base plate 14 and has high connection stability.

[0041] Working principle: When using this mobile phone speaker shell that can prevent deformation, firstly, the opening 15 at the bottom of the shell body 1 is connected with the elastic plastic sheet 17. During the connection process, under the squeezing action of the fixing block 16 with a triangular cross section, the elastic plastic sheet 17 can be stretched into a "Y" shape, which facilitates the quick splicing and installation of the shell body 1 on the base plate 14 and has high connection stability. The support frame 13 with an arc structure can provide more effective support for the shell body 1.

[0042] After the speaker module is installed inside the housing body 1, the sealing cover 6 is precisely aligned and installed on top of the housing body 1 by the engagement of the positioning pin 8 and the limiting hole 2. Then, the fastening bolt 7 is screwed into the screw hole 4 to achieve stable installation of the sealing cover 6. At the same time, the compression plate 10 can be controlled to slide stably to the left by the rectangular guide groove opened inside the connecting plate 11 and the sealing cover 6. Since the thickness of the compression plate 10 increases from left to right, it can compress the connecting pad 902 with the cavity structure inside during its leftward movement. Under the action of gas flow, the connecting folding tube 903 in the contracted state can be extended and opened to fill the gap between the speaker and the sealing cover 6, which can prevent the speaker from vibrating during use and causing vibrato, thus affecting the sound quality of the speaker. After the compression plate 10 is moved to the appropriate position, the connecting plate 11 and the sealing cover 6 can be bolted together to position the compression plate 10.

[0043] During the use of the outer shell 1, the wear-resistant layer 101 made of ceramic material and the reinforcing layer 1023 with braided metal wire inside can effectively improve the wear resistance and strength of the outer shell 1. During long-term use, it can prevent the shell from deforming. The shielding layer 1021 can block electromagnetic interference and avoid affecting the normal voice playback and sound quality of the speaker. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
