Description

Technical Field

[0001] This invention relates to the field of telephone technology, specifically to a speaker mounting mechanism for a mobile phone casing. Background Technology

[0002] Mobile phones, also known as senior citizen phones, are popular among the elderly because of their large speakers, good sound quality, and ability to prevent missed calls. After disassembling the phone's casing, the speaker is installed on the phone's motherboard.

[0003] Currently, when installing a speaker in a mobile phone, the speaker's wiring needs to be organized first. The bottom of the speaker is then soldered using a soldering gun to attach it to the motherboard, securing it with screws. However, because the upper part of the speaker consists of a speaker frame and dust cover, and the size of the frame and dust cover is larger than the bottom magnetic post, the upper frame and dust cover can easily obstruct the soldering gun when soldering the magnetic post to the motherboard. Furthermore, the size limitations of older mobile phones make soldering difficult. Additionally, when soldering the sides of the magnetic post, it's important to maintain a clear view. To facilitate welding torch operation, the basin stand and dust cover are pried open to one side. However, prying open the basin stand and dust cover can easily damage the welding position. There is an existing Chinese utility model patent, application number CN202220114578.X, which proposes a mobile phone speaker mounting mechanism. This solution uses a pryable shell design, but the shell covers the basin stand and dust cover, thus affecting the speaker's sound transmission. At the same time, the speaker's magnetic post is only subjected to force in the part restricted by the shell, making it difficult to fix the speaker completely. Therefore, we propose a mobile phone casing speaker mounting mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide a speaker mounting mechanism for a mobile phone casing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mobile phone casing speaker mounting mechanism, comprising a mobile phone body, a motherboard and a speaker body connected to the mobile phone body, an mounting area on the motherboard, a heat insulation pad mounted on the mounting area, and a mounting plate mounted on the heat insulation pad; a circular hole through which a magnetic post of the speaker body passes is provided at the center of the mounting plate, a mounting sleeve is fitted around the magnetic post of the speaker body, and multiple gradually shaped arc protrusions are distributed at equal angles on the outside of the mounting sleeve; a limiting sleeve is provided on the mounting plate, the inner ring of the limiting sleeve is provided with a sliding groove for sliding the gradually shaped arc protrusions, and the outer ring of the limiting sleeve is provided with multiple sets of limiting grooves, and the limiting grooves and sliding grooves are connected; multiple sets of clamping components are provided on the mounting plate, and the gradually shaped arc protrusions push the clamping components to be fastened in the limiting grooves; multiple sets of adjusting components for clamping the lower part of the speaker body frame are provided at the top of the limiting sleeve.

[0008] Preferably, the clamping assembly includes a clamping plate mounted on a mounting plate, and the clamping plate has a clamping through groove. The limiting groove has a collision body that interacts with the gradually curved protrusion. A clamping block is connected to one side of the collision body. The front end of the clamping block is a plug that passes through the clamping through groove. The lower part of the plug has a pressing protrusion that contacts the bottom edge of the clamping through groove.

[0009] Preferably, a connecting slider is connected to the clamping block, a strip groove is provided on the mounting plate, and a return spring is provided inside the strip groove, one end of the return spring being connected to the connecting slider.

[0010] Preferably, the adjustment assembly includes a bracket plate installed on the top of the limiting sleeve. A bonding plate that fits against the outside of the speaker body frame is connected to the bracket plate. The bonding plate and the bracket plate are inclinedly distributed, and an elastic plate is connected between the bonding plate and the bracket plate. A push rod is installed on the elastic plate, and an adjustment plate is installed on one end of the push rod. The adjustment plate is inserted into the gap between the bonding plate and the bracket plate.

[0011] Preferably, the mounting plate is provided with multiple sets of wire grooves, which are distributed between two adjacent snap-fit ​​plates, and the bottom of the limiting sleeve is also provided with multiple sets of wire grooves.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the design of an installation sleeve and a limiting sleeve, facilitates the installation of the speaker on the main board of the mobile phone by rotating the locking component when it slides in the limiting groove. This avoids the need to swing the speaker's upper frame and dust cover when using a welding gun, making it easier to perform initial fixing. At the same time, compared with the prior art, it fixes the speaker position from multiple directions, reducing the trouble of using a welding gun. The heat insulation pad designed in this invention effectively prevents the bottom of the speaker from directly contacting the motherboard, while also facilitating heat dissipation. The wire channel designed in this invention facilitates the placement of speaker wires, thereby effectively avoiding damage to the wires during installation. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9The present invention provides a technical solution: a mobile phone casing speaker mounting mechanism, including a mobile phone body 1, the bottom of the mobile phone body 1 is a charging cable socket, the side wall is the sound playback area of ​​the speaker, a battery is installed inside the mobile phone body 1, a motherboard 11 and a speaker body 12 are connected to the mobile phone body 1, the motherboard 11 has an installation area 13, a heat insulation pad 2 is installed on the installation area 13, and an installation plate 3 is installed on the heat insulation pad 2; The design of heat insulation pad 2 can be referenced in the appendix. Figure 4 As shown, the heat insulation pad 2 has multiple heat dissipation grooves 21 and multiple alignment holes 22 arranged in a rectangular pattern. A pressing post 15 is installed on the installation area 13, passing through the alignment holes 22. Before installation, the alignment holes 22 on the heat insulation pad 2 are aligned with the pressing post 15. The pressing post 15 is filled with adhesive. After the pressing post 15 passes through the alignment holes 22, pressing it with the thumb causes the adhesive to overflow, allowing the heat insulation pad 2 to adhere to the installation area 13. Alternatively, screws can be used to fix the heat insulation pad 2 to the installation area 13. Using the pressing post 15 facilitates operation.

[0020] Reference Appendix Figure 5 and attached Figure 9 As shown, the mounting plate 3 has a circular hole 31 at its center through which the magnetic post of the speaker body 12 passes. The magnetic post of the speaker body 12 is fitted with a mounting sleeve 4, and the mounting sleeve 4 has multiple gradually curved protrusions 41 distributed at equal angles on its exterior. The mounting plate 3 is provided with a limiting sleeve 5. The inner ring of the limiting sleeve 5 is provided with a sliding groove 51 for sliding the gradually curved protrusions 41. The outer ring of the limiting sleeve 5 is provided with multiple sets of limiting grooves 52, and the limiting grooves 52 and the sliding grooves 51 are connected. The limiting sleeve 5 is provided with multiple sets of extrusion grooves 53. The mounting plate 3 is provided with multiple sets of clamping components 6, and the gradually curved protrusions 41 push the clamping components 6 to be fastened in the limiting groove 52. The top of the limiting sleeve 5 is provided with multiple sets of adjusting components 7 that clamp the lower part of the speaker body 12 frame.

[0021] The horn body 12 has a plug hole 14 on its magnetic post, and the inner ring of the mounting sleeve 4 has a plug post 42 that mates with the plug hole 14.

[0022] The mounting sleeve 4 is an elastic band, and the gradually curved protrusion 41 is made of deformable material. In use, the inner side of the mounting sleeve 4 can be opened by fingers to a certain distance, and the magnetic post at the bottom of the speaker body 12 can be inserted into the mounting sleeve 4. Since the mounting sleeve 4 is an elastic band, it is conducive to the mounting sleeve 4 being tightly attached to the outer side of the magnetic post at the bottom of the speaker body 12. At the same time, since the inner ring of the mounting sleeve 4 is designed with a plug post 42, the plug post 42 is inserted into the plug hole 14, thereby preventing the mounting sleeve 4 from sliding on the outer side of the magnetic post at the bottom of the speaker body 12.

[0023] For the outer clamping part of the magnetic post, please refer to the attached diagram. Figure 5 and attached Figure 7 As shown, the clamping assembly 6 includes a clamping plate 61 mounted on the mounting plate 3, and a clamping through groove 62 is provided on the clamping plate 61. A collision body 63 interacting with the gradually curved protrusion 41 is provided at the limiting groove 52. A clamping block 64 is connected to one side of the collision body 63. The front end of the clamping block 64 is a plug body 65 that passes through the clamping through groove 62. The lower part of the plug body 65 is provided with a pressing protrusion 66 that contacts the bottom edge of the clamping through groove 62. A connecting slider 67 is connected to the clamping block 64. A strip groove 32 is provided on the mounting plate 3, and a recoil spring 68 is provided inside the strip groove 32. One end of the recoil spring 68 is connected to the connecting slider 67. Before the horn body is installed, the collision body 63 is located at the outermost side of the limiting groove 52. Because the mounting sleeve 4 is fitted on the outside of the horn body 12, the upper part of the horn body is rotated by hand, causing the gradually curved protrusion 41 on the mounting sleeve 4 to gradually squeeze the collision body 63, thereby causing the collision body 63 to... Pushing the clamping block 64 and the plug body 65 forward (the connecting slider 67 and the strip groove 32 fixedly connected to the bottom of the clamping block 64 have a limiting effect), when the plug body 65 is inserted into the clamping through groove 62, and at the same time the protrusion 66 is pressed against the position of the clamping through groove 62, at this time the largest part of the gradually curved protrusion 41 just abuts against the collision body 63. At this time, the re-tightening spring 68 is also under pressure, so that the gradually curved protrusion 41 drives the entire limiting sleeve 5 to fit against the guide magnetic post, which plays a limiting role on the speaker body 12.

[0024] The mounting plate 3 is provided with multiple sets of wire grooves 33, which are distributed between two adjacent snap-fit ​​plates. The bottom of the limiting sleeve 5 is also provided with multiple sets of wire grooves 33. When the speaker body 12 is moved, the wire can be erected upwards because the limiting sleeve 5 itself has a certain distance from the mounting plate 3, which facilitates the movement of the wire. When the limiting sleeve 5 is fixedly attached to the speaker body 12, the wire is just inside the wire groove 33, which protects the wire.

[0025] For reference on adjusting the fit of the outer side of the basin frame, please see the attached document. Figure 6 Appendix Figure 7 and attached Figure 9 As shown, the adjustment assembly 7 includes a bracket plate 71 installed on the top of the limiting sleeve 5. A bonding plate 72 is connected to the bracket plate 71 and is attached to the outside of the speaker body 12 frame. The bonding plate 72 and the bracket plate 71 are inclinedly distributed, and an elastic plate 73 is connected between the bonding plate 72 and the bracket plate 71. A push rod 74 is installed on the elastic plate 73, and an adjustment plate 75 is installed on one end of the push rod 74. The adjustment plate 75 is inserted into the gap between the bonding plate 72 and the bracket plate 71. By pushing the push rod 74 forward, the adjustment plate 75 is pushed at the angle between the bonding plate 72 and the bracket plate 71. Since the bonding plate 72 and the bracket plate 71 are glued together, the bonding plate 72 and the bracket plate 71 can be opened. At the same time, the elastic plate 73 is also made of elastic material, which increases the angle between the bonding plate 72 and the bracket plate 71 during the pushing of the push rod 74, making the bonding plate 72 more firmly attached and facilitating the fixation of the upper frame of the speaker body 12.

[0026] Before installation, align the alignment hole 22 on the heat insulation pad 2 with the pressing post 15. The pressing post 15 is filled with adhesive. After the pressing post 15 passes through the alignment hole 22, press it with your thumb to cause the adhesive filling inside the pressing post 15 to overflow. This allows the heat insulation pad 2 to adhere to the installation area 13. The mounting sleeve 4 is an elastic band, and the gradually curved protrusion 41 is made of a deformable material. During use, the inner side of the mounting sleeve 4 can be opened by using your fingers to create a certain gap. The magnetic post at the bottom of the speaker body 12 is inserted into the mounting sleeve 4. Since the mounting sleeve 4 is an elastic band, it allows it to fit tightly against the outer side of the magnetic post at the bottom of the speaker body 12. Simultaneously, the inner ring of the mounting sleeve 4 has a connecting post 42, which inserts into the connecting hole 14, preventing the mounting sleeve 4 from sliding on the outer side of the magnetic post at the bottom of the speaker body 12. Before the speaker body is installed, the collision body 63 is located at the outermost side of the limiting groove 52 because the mounting sleeve 4 is a sleeve... When the speaker body 12 is on the outside, the upper part of the speaker body is held and rotated by hand, causing the gradually curved protrusion 41 on the mounting sleeve 4 to gradually press against the collision body 63. This causes the collision body 63 to push the locking block 64 and the plug body 65 forward (due to the limiting effect of the connecting slider 67 and the strip groove 32 fixedly connected to the bottom of the locking block 64). When the plug body 65 is inserted into the locking through groove 62, and at the same time the protrusion 66 is pressed against the locking through groove 62, the largest part of the gradually curved protrusion 41 is at this time. The protrusion just abuts against the collision body 63. At this time, the recoil spring 68 is also under pressure, which causes the gradually curved protrusion 41 to drive the entire limiting sleeve 5 to fit against the magnetic post, thus limiting the speaker body 12. After the magnetic post of the speaker body 12 is fixed, glue for fixing is introduced from the gap between the limiting sleeve 5 and the speaker body 12, so that the limiting sleeve 5, the speaker body 12 and the mounting plate form a whole, thus avoiding the trouble of welding the speaker to the main board 11 with a welding gun.
