Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a detachable audio module. Background Art

[0002] An audio module is an audio transceiver conversion transmission module that can convert sound signals collected by microphones and other sound pickup devices into electrical signals and audio signals, process audio signals, and perform mutual conversion and transmission between electrical signals and audio signals. For example, audio devices such as speakers, microphones, and headphones will have audio modules, and some audio modules have integrated Bluetooth modules that can transmit electrical signals or audio signals via Bluetooth.

[0003] Some existing audio modules are usually set in a plastic shell. There are two ways to disassemble the plastic shell, one is through a plastic clip, and the other is directly through a bolt. The audio module shell disassembled by the plastic clip usually has a hole on the side, so that the shell can be pried open with fingers or a flat-head screwdriver, so as to facilitate the inspection and replacement of the audio module. However, the sealing is poor, and moisture and water can easily enter through this through hole and affect the module. The audio module shell disassembled by bolts is generally provided with two to four or more bolts. The operation is cumbersome during disassembly and assembly, and the bolts need to be rotated several times to remove them. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a detachable audio module to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detachable audio module, comprising a first shell, a second shell is connected to the top of the first shell, and the cross-sections of the first shell and the second shell are both in the shape of a "U". A positioning column is connected to the lower part of the interior of the first shell, and a limiting plate is connected to one side of the top of the positioning column through a damping shaft, a movable magnet passes through the bottom of the limiting plate, and a fixed magnet passes through the top of the positioning column.

[0006] By adopting the above technical solution, since the first shell and the second shell are in the shape of a U-shaped character, the possibility of moisture and water entering through the gap and directly contacting the audio module body is reduced, thereby improving the sealing performance. At the same time, the positioning group is coordinated with the setting of the limit plate to avoid excessive force when prying the first shell and the second shell apart, causing the audio module body to fly out. When the audio module body needs to be removed, it is only necessary to rotate the positioning column 180 degrees to end the limitation of the audio module body. After reinstalling, it is also only necessary to rotate the positioning column 180 degrees to limit the audio module body. At the same time, the fixed magnet, the movable magnet and the damping shaft are coordinated to prevent the limit plate from rotating at will.

[0007] Furthermore, the limit plate is rotatably connected to the positioning column via a damping shaft.

[0008] By adopting the above technical solution, when the audio module body needs to be removed, the positioning column only needs to be rotated 180 degrees to end the limitation of the audio module body. After reinstalling, the positioning column only needs to be rotated 180 degrees to limit the audio module body.

[0009] Furthermore, eight fixed magnets are provided and four movable magnets are provided.

[0010] By adopting the above technical solution, the limit plate is rotated 180 degrees so that the center of the limit plate and the center of the positioning column are on the same line. At the same time, the movable magnet corresponds to a fixed magnet and cooperates with the damping shaft to prevent the limit plate from rotating at will.

[0011] Furthermore, the four movable magnets are detachably connected to the eight fixed magnets respectively.

[0012] By adopting the above technical solution, the staff rotates the limit plate 180 degrees so that the center of the limit plate deviates from the center of the positioning column, thereby limiting the main body of the audio module. At the same time, the movable magnet corresponds to another fixed magnet and cooperates with the damping shaft to prevent the limit plate from rotating at will.

[0013] Furthermore, a handle is provided on one side of the top of the limiting plate.

[0014] By adopting the above technical solution and setting the handle, it is convenient for the staff to rotate the limit plate 180 degrees to limit or end the limit of the audio module body.

[0015] Furthermore, mounting feet are connected to both sides of the outer surface and both sides of the back of the first shell, an audio module body is placed in the middle of the first shell, and a cable is connected to the top of the audio module body, card plates are connected to both sides of the first shell, notches are provided on one side of the first shell and the second shell, a sealing ring passes through one side of the top of the second shell, and the cable passes through the top and bottom of the sealing ring, and buckles are connected to both sides of the bottom of the second shell.

[0016] By adopting the above technical solution, the staff places the audio module in the device, then passes the bolts through the mounting feet to limit it, and then the staff connects the end of the cable away from the audio module body to the device circuit to complete the installation operation.

[0017] Furthermore, the buckle abuts against the clamping plate, and the second shell is detachably connected to the first shell via the clamping plate and the buckle.

[0018] By adopting the above technical solution, a flat-blade screwdriver or a fingernail is inserted into the notch, and then the staff lifts up the second shell to separate the buckle from the card plate, thereby separating the second shell from the first shell.

[0019] Furthermore, both sides of the top of the first shell and both sides of the bottom of the second shell are connected with a first sealing gasket and a second sealing gasket.

[0020] By adopting the above technical solution, the first sealing gasket cooperates with the second sealing gasket to further increase the sealing performance and effectively reduce the entry of moisture and water.

[0021] Furthermore, the first sealing gasket and the second sealing gasket are both made of rubber material.

[0022] By adopting the above technical solution, the first sealing pad and the second sealing pad made of rubber have good elasticity and can fill the gap to reduce the entry of moisture and water.

[0023] In summary, the utility model mainly has the following beneficial effects:

[0024] The utility model arranges a first shell, a second shell, a limiting plate, a damping shaft, a fixed magnet, a movable magnet and a positioning column. Since the first shell and the second shell are in the shape of a U-shaped character, the possibility of moisture and water entering through the gap and directly contacting the audio module body is reduced, thereby improving the sealing performance. At the same time, the positioning group cooperates with the arrangement of the limiting plate to avoid excessive force when the first shell and the second shell are opened, causing the audio module body to fly out. When the audio module body needs to be removed, it is only necessary to rotate the positioning column 180 degrees to end the limiting of the audio module body. After reinstalling, it is also only necessary to rotate the positioning column 180 degrees to limit the audio module body. At the same time, the fixed magnet, the movable magnet and the damping shaft cooperate to prevent the limiting plate from rotating at will. It is convenient for disassembly and assembly and effectively reduces the possibility of moisture and water contacting the audio module body. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The following describes an embodiment of the utility model based on its overall structure.

[0033] Embodiment 1:

[0034] A detachable audio module, such as Figure 1-Figure 5 As shown, it includes a first shell 1, and the top of the first shell 1 is connected to the second shell 2. The cross-sections of the first shell 1 and the second shell 2 are both in the shape of a "U", thereby reducing the possibility of moisture and water entering and directly contacting the audio module body, and improving the sealing performance; four positioning columns 16 are connected to the lower part of the first shell 1, and the top side of the four positioning columns 16 is respectively connected to four limit plates 12 through four damping shafts 13, and a handle is provided on the top side of the limit plate 12. The four limit plates 12 are rotatably connected to the four positioning columns 16 through the damping shaft 13. The staff rotates the limit plate 12 180 degrees to deviate the center of the limit plate 12 from the center of the positioning column 16, thereby limiting the audio module body 9; four movable magnets 15 are respectively passed through the bottom of the four limit plates 12, and eight fixed magnets 14 are respectively passed through the top of the four positioning columns 16. The four movable magnets 15 are respectively detachably connected to the eight fixed magnets 14, and the movable magnet 15 corresponds to a fixed magnet 14 and cooperates with the damping shaft 13, thereby preventing the limit plate 12 from rotating at will.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 5In the above embodiment, both sides of the outer surface of the first shell 1 and both sides of the back are connected with mounting feet 3. The staff places the audio module in the device and then passes the bolts through the mounting feet 3 to limit it; an audio module body 9 is placed in the middle of the first shell 1, and a cable 4 is connected to the top of the audio module body 9 to facilitate the conversion, processing and transmission of audio signals; a card board 10 is connected to both sides of the first shell 1, a notch 6 is opened on one side of the first shell 1 and the second shell 2, and buckles 11 are connected to both sides of the bottom of the second shell 2, and the buckles 11 are abutted against the card board 10. The second shell 2 is detachably connected to the first shell 1 through the card board 10 and the buckle 11, and a flat-head screwdriver or a fingernail is inserted into the notch 6. Then the staff tilts the second shell 2 upward to separate the buckle 11 from the card board 10, thereby separating the second shell 2 from the first shell 1; a sealing ring 5 is passed through one side of the top of the second shell 2, and the cable 4 passes through the top and bottom of the sealing ring 5, and the gap between the cable 4 and the second shell 2 is filled by the sealing ring 5.

[0036] Embodiment 2:

[0037] On the basis of the above-mentioned embodiment 1, although the first shell 1, the second shell 2, the limit plate 12, the damping shaft 13, the fixed magnet 14, the movable magnet 15 and the positioning column 16 are provided, it is possible to facilitate disassembly and assembly and effectively reduce the possibility of moisture and water contacting the audio module body 9; however, there are errors in the precision of the components during production, which may result in a gap between the first shell 1 and the second shell 2, which may still cause moisture and water to enter and contact the audio module body 9; now, by providing the first sealing gasket 7 and the second sealing gasket 8, the entry of moisture and water can be effectively reduced.

[0038] See also Figure 2 , Figure 3 and Figure 5 In the above embodiment, the first and second sealing gaskets 7 and 8 are connected to both sides of the top of the first shell 1 and both sides of the bottom of the second shell 2. The first and second sealing gaskets 7 and 8 are both made of rubber material. The first and second sealing gaskets 7 and 8 cooperate with each other to further increase the sealing performance and effectively reduce the entry of moisture and water.

[0039] The implementation principle of the utility model is as follows: first, the staff places the audio module in the device, then passes the bolt through the mounting foot 3 to limit it, and then the staff connects the end of the cable 4 away from the audio module body 9 to the device circuit to complete the installation operation;

[0040] When the audio module body 9 needs to be disassembled for maintenance or replacement, the staff inserts a flat-blade screwdriver or a fingernail into the notch 6, and then the staff tilts up the second shell 2 to separate the buckle 11 from the card plate 10, thereby separating the second shell 2 from the first shell 1, and at the same time limits the audio module body 9 through the limit plate 12 to prevent the audio module body 9 from flying out due to excessive force when prying the first shell 1 and the second shell 2. Then the staff rotates the limit plate 12 180 degrees so that the center of the limit plate 12 is on the same line as the center of the positioning column 16, and at the same time the movable magnet 15 corresponds to a fixed magnet 14 and cooperates with the damping shaft 13, thereby preventing the limit plate 12 from rotating at will, and then the staff unplugs the end of the cable 4 close to the audio module body 9 from the audio module body 9, and at this time the staff can directly remove the audio module body 9 for repair or replacement;

[0041] During installation, the staff puts the audio module body 9 into the first shell 1, and the positioning column 16 penetrates the audio module body 9. Then the staff rotates the limit plate 12 180 degrees to make the center of the limit plate 12 deviate from the center of the positioning column 16, thereby limiting the audio module body 9. At the same time, the movable magnet 15 corresponds to another fixed magnet 14 and cooperates with the damping shaft 13 to prevent the limit plate 12 from rotating at will. Then the staff inserts the cable 4 into the audio module body 9 and merges the second shell 2 with the first shell 1. Then the staff presses down the second shell 2 with force to install the second shell 2 on the top of the first shell 1 through the card plate 10 and the buckle 11;

[0042] After installation, since the first shell 1 and the second shell 2 are in the shape of a U-shape, the possibility of moisture and water entering through the gap 6 and directly contacting the audio module body 9 is reduced, thereby improving the sealing performance. At the same time, the first sealing gasket 7 cooperates with the second sealing gasket 8 to further increase the sealing performance, effectively reducing the entry of moisture and water. At the same time, the gap between the cable 4 and the second shell 2 is filled by the sealing ring 5.
