[0028] In some embodiments, as Figure 1 and Figure 2 As shown, this embodiment provides a recording device, including a device body 1 and a microphone module 2 that is detachably mounted on one end of the device body 1. The microphone module 2 includes a shell 21 and a microphone 22 disposed in the shell 21. One of the device body 1 and the shell 21 is provided with a card block 11, and the other is provided with a card slot 211. The card block 11 is pluggable and mounted in the card slot 211. The shell 21 is provided with a first connector 212. The first connector 212 is electrically connected to the microphone 22. The device body 1 is provided with a second connector 12. When the card block 11 is mounted in the card slot 211, the first connector 212 is electrically connected to the second connector 12.

[0029] Specifically, the microphone module 2 can be detachably mounted on the top, bottom or side wall of the device body 1. In order to facilitate the assembly of the microphone 22, the housing 21 optionally includes a first housing and a second housing that are detachably connected. The first housing and the second housing can be fixed together using a snap-fit ​​structure or screws. The first housing and the second housing enclose a receiving cavity. Figure 3 As shown, the microphone 22 is accommodated in the accommodating cavity and is fastened to the wall of the accommodating cavity by means of foam rubber 214 .

[0030] In some embodiments, as Figure 1 As shown, the card slot 211 is provided at the connection end between the housing 21 and the device body 1, and the card block 11 is protruded from the device body 1. Of course, the card slot 211 can also be provided on the device body 1, and the card block 11 is protruded from the side of the housing 21 facing the device body 1.

[0031] The first connector 212 is adapted to the second connector 12. Figure 1 and Figure 2 As shown, the first connector 212 is provided on the side of the housing 21 facing the device body 1. The microphone 22 is provided with a wire 221, and the wire 221 is used to electrically connect the microphone 22 and the first connector 212. When the card slot 211 is provided in the housing 21, the first connector 212 can be provided at the bottom of the card slot 211, and the second connector 12 can be provided on the top surface of the card block 11. Alternatively, the first connector 212 can be provided on one side of the card slot 211, and the second connector 12 can be provided on the corresponding side of the card block 11. Multiple microphones 22 can be provided to ensure the sound reception effect of the recording device. For example, two, three, or five microphones 22 can be provided. A corresponding first connector 212 is provided for each microphone 22. The number of second connectors 12 and first connectors 212 is consistent with the number of microphones 22. Of course, multiple microphones 22 can also be electrically connected to the device body 1 through a pair of second connectors 12 and first connectors 212. Optionally, the first connector 212 is a flexible electrical connector, a USB connector, a Type-C connector or a Light connector, and the second connector 12 is an electrical jack, a USB jack, a Type-C jack or a Light jack that is compatible with the first connector 212 .

[0032] In a specific embodiment, if Figure 1As shown, the card slot 211 is provided on the shell 21, the card block 11 is protruded from the device body 1, the first connector 212 is provided on one side of the card slot 211, and the second connector 12 is provided on one side of the card block 11. The outer shell of the device body 1 is provided with a connection hole 215 corresponding to the second connector 12. The electric control board 14 is installed in the device body 1. The microphone 22 is electrically connected to the first connector 212, the first connector 212 is electrically connected to the second connector 12, and the second connector 12 is electrically connected to the electric control board 14, thereby realizing the communication connection between the microphone 22 and the electric control board 14. During assembly, it is only necessary to clamp the card block 11 into the card slot 211, and the first connector 212 is electrically connected to the second connector 12 through the connection hole 215, so as to realize the communication connection between the microphone 22 and the electric control board 14, and the entire microphone module 2 is firmly fixed on the device body 1. When the microphone 22 needs to be replaced, the microphone module 2 can be separated from the device body 1 by simply pulling the card block 11 out of the card slot 211, and then the new microphone module 2 can be snapped into the device body 1. Users can replace different types of microphone modules 2 for recording according to actual needs or changes in recording occasions. Assembly and disassembly are convenient, and the recording device can always maintain excellent recording quality.

[0033] This embodiment provides a recording device, wherein the microphone module 2 includes a shell 21 and a microphone 22 arranged in the shell 21. One of the device body 1 and the shell 21 is provided with a card block 11, and the other is provided with a card slot 211. The shell 21 is provided with a first connector 212 electrically connected to the microphone 22, and the device body 1 is provided with a second connector 12. During assembly, the card block 11 only needs to be snapped into the card slot 211 to fix the microphone module 2 on the device body 1. The first connector 212 and the second connector 12 are electrically connected to realize the communication connection between the microphone 22 and the device body 1, thereby ensuring the recording function of the recording device; when the microphone 22 needs to be replaced, the card block 11 is pulled out of the card slot 211 to realize the separation of the microphone module 2 and the device body 1. At this time, only the new microphone module 2 needs to be snapped into the device body 1. The user can quickly replace the corresponding type of microphone 22 according to the changes in the recording occasion, ensuring that the recording device always has better recording quality, and the microphone module 2 is easy to assemble and disassemble, which improves the user experience.

[0034] In some embodiments, as Figure 3 and Figure 4 As shown, one of the card block 11 and the card slot 211 is installed with an elastic card head 13, and the other is provided with a positioning groove 213. Figure 2 As shown, when the clamping block 11 is clamped in the clamping slot 211 , the elastic clamping head 13 is clamped in the positioning slot 213 .

[0035] Specifically, in one embodiment, the elastic clamp head 13 is retractably mounted on the clamp block 11, and a positioning groove 213 is provided on one side wall of the clamping groove 211. Figure 1 As shown, at least a portion of the elastic clamp 13 extends outward from the card block 11. During assembly, the card block 11 slides into the card slot 211 along the slot walls of the card slot 211. The elastic clamp 13 retracts into the interior of the card block 11 under the squeezing action of the slot walls of the card slot 211. As the card block 11 continues to slide in, the elastic clamp 13 extends outward from the card block 11 and is inserted into the positioning groove 213 to prevent the card block 11 from sliding out of the card slot 211. The cooperation between the elastic clamp 13 and the positioning groove 213 locks the microphone module 2 to the device body 1, ensuring the stability of the connection between the microphone module 2 and the device body 1.

[0036] Optionally, the number of elastic clamps 13 can be multiple. Figure 1 As shown, elastic clamping heads 13 are respectively provided on opposite sides of the clamping block 11 . Correspondingly, positioning grooves 213 are respectively provided on the groove walls on opposite sides of the clamping groove 211 .

[0037] Alternatively, the elastic clamping head 13 can be retractably mounted on a side wall of the clamping slot 211 , and the positioning slot 213 is provided on a side surface of the clamping block 11 , which can also achieve the same effect.

[0038] like Figure 2 and Figure 4 As shown, in some embodiments, the elastic clamp 13 includes a wedge block 131 and an elastic member 132. The clamp 11 is provided with a mounting slot 111. The wedge block 131 is retractably mounted in the mounting slot 111. One end of the elastic member 132 abuts against the wedge block 131, and the other end abuts against the bottom of the mounting slot 111.

[0039] Specifically, if Figure 4 As shown, the mounting groove 111 is provided on one side of the clamping block 11. The end of the wedge block 131 close to the notch of the mounting groove 111 has a wedge-shaped surface to ensure that the clamping block 11 can slide smoothly along the groove wall of the clamping groove 211, and to ensure that the wedge block 131 can be smoothly retracted into the mounting groove 111 after being squeezed by the groove wall of the clamping groove 211. Among them, the elastic member 132 can be a spring. The expansion and contraction direction of the spring is consistent with the expansion and contraction direction of the wedge block 131. The spring is sleeved on the wedge block 131 and is fixedly connected to the bottom of the mounting groove 111 and the wedge block 131 respectively, so that the wedge block 131 can be pushed out of the mounting groove 111 by the elastic action of the spring and firmly clamped in the positioning groove 213.

[0040] In a specific embodiment, Figure 4 As shown, the device body 1 is provided with a clamping block 11. An elastic clamping head 13 is mounted on the clamping block 11. An electromagnetic component 112 is mounted inside the clamping block 11. The electromagnetic component 112 is electrically connected to the electric control board 14. When the electromagnetic component 112 is powered on, the electromagnetic component 112 and the wedge block 131 are attracted to each other.

[0041] In this embodiment, the wedge block 131 is a magnetic structure, and the magnetic poles of the wedge block 131 are opposite to the magnetic poles of the electromagnetic component 112. Optionally, the wedge block 131 is a permanent magnet and the electromagnetic component 112 is an electromagnet. Alternatively, the wedge block 131 is made of iron. When the microphone module 2 needs to be disassembled, the electric control board 14 controls the electromagnetic component 112 to be energized, so that the electromagnetic component 112 is magnetic, and the electromagnetic component 112 and the wedge block 131 are magnetically attracted to each other, and the wedge block 131 is attracted to be retracted into the installation slot 111, so that the card block 11 can be smoothly pulled out of the card slot 211. During the research and development stage, the single power-on time of the electromagnetic component 112 can be set, for example, 5 seconds or 10 seconds. During the power-on time of the electromagnetic component 112, the user quickly pulls the card block 11 out of the card slot 211 to complete the disassembly operation of the microphone module 2. The electromagnetic component 112 is automatically powered off after being powered on for a preset period of time, and the wedge-shaped block 131 extends out of the mounting slot 111 under the elastic force of the elastic component 132 .

[0042] like Figure 2 As shown, there are two mounting grooves 111, which are connected by a through hole. The electromagnetic component 112 extends along the protruding direction of the block 11 and passes through the through hole in the radial direction of the through hole. Therefore, when the electromagnetic component 112 is energized, it can be directly attracted to the wedge block 131, avoiding the obstruction of the bottom of the mounting groove 111 affecting the attraction force.

[0043] In some embodiments, the device body 1 is equipped with a control key, which is electrically connected to the electric control board 14 to control the power state of the electromagnetic element 112 .

[0044] Specifically, the control key is provided on the side of the device body 1. Optionally, the control key is a press-type key, a knob-type key or a sliding-type key. When the microphone module 2 needs to be disassembled, the user triggers the control key, and the electronic control board 14 controls the electromagnetic component 112 to be energized based on the trigger signal of the control key. The electromagnetic component 112 attracts the wedge block 131 to exit the positioning groove 213, and the microphone module 2 is unlocked so that the user can quickly remove the microphone module 2. After the disassembly is completed, the user triggers the control key again, and the electronic control board 14 controls the electromagnetic component 112 to be de-energized. The wedge block 131 extends out of the mounting groove 111 under the elastic force of the elastic component 132, thereby reducing power consumption. When assembling the microphone module 2, the user triggers the control key again, the electronic control board 14 controls the electromagnetic component 112 to cut off the power, and the wedge block 131 extends out of the installation slot 111 under the elastic force of the elastic component 132, so that when the card block 11 is clamped in the card slot 211, the wedge block 131 is inserted into the positioning slot 213, thereby increasing the stability of the connection between the microphone module 2 and the device body 1.

[0045] In other embodiments, the device body 1 does not have control keys. A touch screen is mounted on the front of the device body 1, and the touch screen is electrically connected to the electronic control board 14. The user can input control commands to the electronic control board 14 by touching the touch screen, so that the electronic control board 14 controls the power supply state of the electromagnetic element 112.

[0046] The device body 1 is also equipped with a speaker, which is electrically connected to the electronic control board 14. In addition to recording, the recording device can also interact with the user through voice communication via the microphone 22 and speaker. Furthermore, the electronic control board 14 can display the voice interaction information or the recording information from the microphone 22 on the touch screen for the user to view, making the recording device more convenient to use.

[0047] In some embodiments, the mounting groove 111 is a stepped groove. The wedge block 131 has a stepped surface. When the elastic clamp 13 is retracted into the mounting groove 111, the stepped surface abuts against the stepped surface of the stepped groove.

[0048] Specifically, the mounting slot 111 has a wide opening and a narrow bottom, forming a stepped surface in the middle. When the electromagnetic element 112 is installed in the clamping block 11 and the microphone module 2 needs to be removed, the electromagnetic element 112 is energized to attract the wedge block 131 toward the bottom of the mounting slot 111, causing the stepped surface to abut against the stepped surface of the stepped slot, thereby restricting the wedge block 131 from retracting into the mounting slot 111. When the electromagnetic element 112 is de-energized, the wedge block 131 extends out of the mounting slot 111 under the elastic force of the elastic element 132.

[0049] Further, if Figure 2 and Figure 4 As shown, in some embodiments, elastic clamps 13 are installed on opposite sides of the card block 11. Mounting grooves 111 are respectively provided on opposite sides of the card block 11. Positioning grooves 213 are respectively provided on opposite side walls of the card groove 211. The two elastic clamps 13 are respectively telescopically installed in the two mounting grooves 111. When the card block 11 is mounted in the card groove 211, the two elastic clamps 13 are respectively mounted in the two positioning grooves 213 in a one-to-one correspondence, so as to further lock the microphone module 2 at the same time through the two elastic clamps 13, thereby increasing the connection stability between the microphone module 2 and the device body 1.

[0050] In some embodiments, as Figure 2 and Figure 4 As shown, the direction of extension and contraction of the elastic clamp head 13 is perpendicular to the direction in which the clamping block 11 is inserted into the clamping slot 211. Therefore, in addition to being restrained by the walls of the clamping slot 211, the elastic clamp head 13 and the positioning slot 213 can also prevent the clamping block 11 from falling out of the clamping slot 211, thereby improving the stability of the connection between the microphone module 2 and the device body 1.

[0051] Optionally, the direction of expansion and contraction of the elastic clamp 13 is consistent with the width direction of the device body 1, and the direction in which the clamping block 11 is inserted into the clamping slot 211 is consistent with the length direction of the device body 1. Of course, the direction of expansion and contraction of the elastic clamp 13 can also be different from the width direction of the device body 1, as long as the direction of expansion and contraction of the elastic clamp 13 is perpendicular to the direction in which the clamping block 11 is inserted into the clamping slot 211.

[0052] The extending direction of the positioning slot 213 is perpendicular to the extending direction of the card slot 211. The wedge block 131 is inserted vertically into one side wall of the card slot 211 under the elastic action of the elastic member 132. One end of the wedge block 131 with a wedge-shaped surface abuts against the wall of the positioning slot 213 to prevent the card block 11 from sliding out of the card slot 211, thereby ensuring the stability of the connection between the microphone module 2 and the device body 1.

[0053] Of course, the direction in which the elastic clamp 13 extends and contracts can also be set at an acute angle, such as 80°, 60°, or 55°, to the direction in which the clamping block 11 is inserted into the clamping slot 211, without specific limitation. Alternatively, the elastic clamp 13 can be positioned at the bottom of the clamping slot 211 or at the end of the clamping block 11, so that the direction in which the elastic clamp 13 extends and contracts is aligned with the direction in which the clamping block 11 is inserted into the clamping slot 211, thereby preventing the clamping block 11 from rocking left or right.

[0054] like Figure 2 As shown, when the card block 11 is mounted in the card slot 211 , the outer wall of the shell 21 is flush with the outer wall of the device body 1 , so as to ensure the aesthetics of the recording device.

[0055] In some embodiments, one of the first connector 212 and the second connector 12 is an elastic electrical connector, and the other is an electrical jack. Optionally, the first connector 212 is an elastic electrical connector, and the second connector 12 is an electrical jack adapted to the elastic electrical connector. Alternatively, the first connector 212 is an electrical jack, and the second connector 12 is an elastic electrical connector. When the card block 11 is mounted in the card slot 211, the elastic electrical connector is plugged into the electrical jack. The elastic electrical connector has certain elasticity, flexibility, and buffering properties to ensure the tightness of the connection between the first connector 212 and the second connector 12, ensure good electrical connection between the microphone 22 and the electronic control board 14, and ensure the reliability of the first connector 212 during frequent plugging and unplugging.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
