[0040] Please refer to the reference. Figures 1 to 9This application proposes a voice recorder 100. In one embodiment of this application, the voice recorder 100 includes a first housing 10, a second housing 20, a connection structure 30, and a motherboard 40. The first housing 10 includes a first plate 11 and a first side plate 12. The first side plate 12 is arranged around the first plate 11 in a circumferential direction and surrounds the first plate 11 to form a receiving groove 13. A clamping structure 14 is provided in the receiving groove 13. The clamping structure 14 and the first plate 11 surround to form a clamping gap 141 with the opening facing the groove of the receiving groove 13. The second housing 20 covers the groove of the receiving groove 13 and surrounds the receiving groove 13 to form a receiving cavity 21. The second housing 20 includes a second plate 22 and a second side plate 23 connected to each other. The second plate 22 is arranged at a distance from the first plate 11. The second side plate 23 is inserted into the clamping gap 141. A connecting structure 30 is provided between the first side plate 12 and the second side plate 23 to connect the first side plate 12 and the second side plate 23. A main board 40 is provided in the receiving cavity 21. The main board 40 is provided with a microphone 41.

[0041] The first housing 10 and the second housing 20 can overlap each other to form a receiving cavity 21, providing space for the motherboard 40 and other components of the voice recorder 100. The motherboard 40 and other components of the voice recorder 100 can be entirely housed within the receiving groove 13 formed by the first housing 10; alternatively, they can be partially housed within the receiving groove 13 and partially within the second housing 20. Furthermore, on a projection plane perpendicular to the arrangement direction of the first housing 10 and the second housing 20, for example, when the second housing 20 is placed on top of the first housing 10, the projection of the housing structure formed by the combination of the first housing 10 and the second housing 20 on a projection plane perpendicular to the vertical direction can be rectangular, square, or circular, etc. This application does not limit the shape of the housing structure. Furthermore, the second side plate 23 in the second housing 20 can be a ring shape that surrounds the second plate 22 in the circumference; it can also be a strip and distributed on opposite sides of the second plate 22; or it can be multiple spaced plate segments arranged in the circumference of the second plate 22, ensuring that it can extend into the first housing 10 and connect with the first side plate 12. This application does not limit the shape type of the second side plate 23.

[0042] The clamping structure 14 can be connected to the first plate 11, the first side plate 12, or both. This application does not limit the connection objects of the clamping structure 14. Furthermore, the number of clamping structures 14 can be one, two, or more, and they can be located on one side or all around the first housing 10. This application does not limit the location of the clamping structures 14. Additionally, the clamping structure 14 can be block-shaped, plate-shaped, or column-shaped, as described below. This application does not limit the shape or structure type of the clamping structure 14, as long as at least a portion is spaced relative to the first side plate 12 to form a clamping gap 141 for the insertion of the second side plate 23 of the second housing 20.

[0043] The connecting structure 30 can be used to connect the first side plate 12 and the second side plate 23. The connecting structure 30 can be a combination of the buckle 31 and the snap hole 32 as described below, or it can be an adhesive layer, such as glue or double-sided tape.

[0044] The motherboard 40 can be used to control the operation of the voice recorder 100, such as turning it on, starting recording, turning off recording, or turning it off. The motherboard 40 can be a circuit board integrating a control chip, an analog front-end, an analog-to-digital converter, a digital signal processor, and a storage unit 42. After the microphone 41 acquires external sound through the pickup hole 121 on the first housing 10 and / or the second housing 20, it converts the sound waves into analog electrical signals. The analog front-end then amplifies the weak signal using a preamplifier and removes high-frequency noise or low-frequency interference using a filter. The analog-to-digital converter then converts the analog signal into a digital signal. The digital signal processor then performs noise reduction, echo cancellation, and voice enhancement processing. Finally, the main control chip manages the recordings and stores them in the storage unit 42. Since the recording function of the voice recorder 100 is existing technology, the specific structure and operation of the motherboard 40 will not be described in detail here.

[0045] The voice recorder 100 of this application utilizes a connecting structure 30 between the first side plate 12 of the first housing 10 and the second side plate 23 of the second housing 20. This allows for easy assembly of the two housings when they are aligned and closed, thus improving the convenience of assembling the voice recorder 100. Simultaneously, a clamping gap 141 is provided within the first housing 10, which cooperates with the first side plate 12 to clamp and limit the second side plate 23 extending into the second housing 20. This allows the outer side of the second side plate 23 to be connected via the connecting structure 30, while the inner side is abutted and limited by the clamping structure 141, thereby improving the stability of the assembly between the first housing 10 and the second housing 20. Furthermore, this design allows for a concealed connection between the first and second housings 20, protecting the connecting structure 30. It also enhances the aesthetic appeal of the voice recorder 100.

[0046] Please refer to the reference. Figure 6 ,as well as Figures 8 to 11 In one embodiment of this application, the connecting structure 30 includes a buckle 31 and a buckle hole 32. One of the buckle 31 and the buckle hole 32 is provided on the first side plate 12, and the other is provided on the second side plate 23. The buckle 31 is engaged with the buckle hole 32.

[0047] In this embodiment, the connecting structure 30 is configured to include a snap-fit ​​31 and a snap-fit ​​hole 32, enabling the first side plate 12 and the second side plate 23 to be snap-fit ​​connected. This snap-fit ​​connection is simple and reliable, thereby improving the stability and convenience of assembling the first housing 10 and the second housing 20. Specifically, the snap-fit ​​31 can be located on the first side plate 12, and the snap-fit ​​hole 32 on the second side plate 23; alternatively, the snap-fit ​​31 can be located on the second side plate 23, and the snap-fit ​​hole 32 on the first side plate 12.

[0048] Please refer to the reference. Figure 10 and Figure 11 In one embodiment of this application, a buckle 31 is provided on the first side plate 12, and a buckle hole 32 is provided on the second side plate 23. The thickness of the second side plate 23 in the area where the buckle hole 32 is provided is greater than the thickness of other areas.

[0049] In this embodiment, the buckle 31 and the buckle hole 32 are respectively disposed on the first side plate 12 and the second side plate 23, with the first side plate 12 covering the outside of the second side plate 23. Since the first side plate 12 does not require the buckle hole 32, its thickness is not affected, resulting in high strength and thus providing good protection on the outside. Furthermore, by setting the thickness of the second side plate 23 in the area with the buckle hole 32 to be greater than the thickness in other areas, the strength of the second side plate 23 in the area with the buckle hole 32 is not significantly affected by the buckle hole 32, improving the stability of the engagement between the buckle 31 and the buckle hole 32.

[0050] Please refer to the reference. Figure 6 ,as well as Figure 8 middle Figure 11 In one embodiment of this application, the buckle 31 and / or the second side plate 23 are provided with a first guide surface 311 to guide the buckle 31 into the buckle hole 32.

[0051] In this embodiment, the first guide surface 311 is provided so that when the second housing 20 is covered onto the first housing 10, the first guide surface 311 can guide the deformation of the buckle 31 or the buckle hole 32, thereby facilitating the buckle 31 to engage with the buckle hole 32 and improving the smoothness of the engagement and assembly of the first housing 10 and the second housing 20. The first guide surface 311 may be provided on only one of the buckle 31 and the second side plate 23, or it may be provided on both. Furthermore, the first guide surface 311 can be a chamfered structure or a rounded corner structure.

[0052] Please refer to the reference. Figure 6 , Figure 8 as well as Figure 10 In one embodiment of this application, there are multiple buckles 31 and buckle holes 32, which are arranged circumferentially along the receiving groove 13, and each buckle 31 is engaged with a buckle hole 32.

[0053] In this embodiment, multiple buckles 31 and buckle holes 32 are arranged circumferentially along the receiving groove 13, so that the first housing 10 and the second housing 20 can have multiple buckle force receiving points in the circumferential direction, which is conducive to improving the stability of the connection and assembly between the first housing 10 and the second housing 20.

[0054] Please refer to the reference. Figures 7 to 9In one embodiment of this application, the clamping structure 14 includes a stop block 142 and a clamping block 143. The stop block 142 is connected to the first plate 11 and / or the first side plate 12. The clamping block 143 is connected to the side of the stop block 142 facing the second plate 22 and forms a clamping gap 141 with the stop block 142 and the first side plate 12. The stop block 142 abuts against the side of the second side plate 23 facing the first plate 11.

[0055] In this embodiment, the clamping structure 14 is configured to include a stop block 142 and a clamping block 143, such that the clamping block 143 can clamp the second side plate 23 extending into the first housing 10, while the stop block 142 acts as a stop for the extension stroke. The stop block 142 can be connected to one of the first plate 11 and the first side plate 12, or it can be connected to both.

[0056] Please refer to the reference. Figures 7 to 9 In one embodiment of this application, the clamping block 143 and / or the second side plate 23 are provided with a second guide surface 144 to guide the second side plate 23 to be inserted into the clamping gap 141.

[0057] In this embodiment, the second guide surface 144 is provided so that when the second housing 20 is covered onto the first housing 10, the second guide surface 144 can guide the second side plate 23 to be accurately inserted into the clamping gap 141, thereby improving the smoothness of the snap-fit ​​assembly of the first housing 10 and the second housing 20. The second guide surface 144 may be provided on only one of the clamping block 143 and the second side plate 23, or it may be provided on both. Furthermore, the second guide surface 144 can be a chamfered structure or a rounded corner structure.

[0058] Please refer to the reference. Figure 7 and Figure 8 In one embodiment of this application, there are multiple clamping structures 14, which are arranged circumferentially along the receiving groove 13.

[0059] In this embodiment, multiple clamping structures 14 are arranged circumferentially along the receiving groove 13, so that the second housing 20 can have multiple clamping force points in the circumferential direction, which is beneficial to improving the clamping stability of the second housing 20.

[0060] Please refer to the reference. Figure 1 and Figure 6 In one embodiment of this application, the second side plate 23 is arranged around the first plate 11 in the circumferential direction, and the side of the second plate 22 facing away from the first plate 11 is coplanar with the first side plate 12.

[0061] In this embodiment, the second side plate 23 is arranged around the circumference of the first plate 11, and the side of the second plate 22 facing away from the first plate 11 is coplanar with the first side plate 12. This increases the contact area between the first shell 10 and the second shell 20, and also facilitates the arrangement of multiple connecting structures 30 and multiple clamping structures 14, thereby improving the stability of the connection and assembly of the first shell 10 and the second shell 20. Moreover, the fact that the side of the second plate 22 facing away from the first plate 11 is coplanar with the first side plate 12 helps to reduce the overall thickness of the shell structure formed by the combination of the first shell 10 and the second shell 20, thus improving the lightweight effect.
