[0029] The following is combined with Figures 1-7 The recording pen provided in this utility model will be described in detail through specific embodiments and application scenarios.

[0030] like Figure 1 and Figure 2 As shown, this utility model provides a voice recorder, including: a pen shell 1, a protective mesh 2, a microphone 3, a first fastener 4, and a mounting bracket 5. The mounting bracket 5 has a first fastening hole 52. The mounting bracket 5 is fixed inside the protective mesh 2 to form a receiving cavity between them, and the microphone 3 is housed within the receiving cavity. The protective mesh 2 is fixedly installed at one end of the pen shell 1. The mounting bracket 5 engages with the inner wall of the protective mesh 2 through a snap-fit ​​mechanism, and the first fastener 4 passes through the first fastening hole 52 to fix the mounting bracket 5 to the protective mesh 2.

[0031] Specifically, the protective mesh 2 has a cavity. The mounting bracket 5 and the cavity wall engage with each other and are locked together by means of a first fastener 4. The mounting bracket 5 and the protective mesh 2 are fixed together to form a receiving cavity for accommodating the microphone 3. The pickup end and the wiring end of the microphone 3 are opposite each other, wherein the microphone 3 is sandwiched between the inner walls of the mounting bracket 5 and the protective mesh 2. Optionally, one of the inner walls of the mounting bracket 5 and the protective mesh 2 is provided with a buckle, and the other is provided with a slot, the buckle being engaged with the slot to achieve quick assembly of the mounting bracket 5 and the protective mesh 2.

[0032] The first fastener 4 can be a screw or a pin. For example... Figure 3As shown, the mounting bracket 5 has a connecting ear 54, and the connecting ear 54 has a first fastening hole 52. A corresponding connecting post is provided on the inner wall of the protective net 2, and the connecting post has a first mounting hole. The connecting ear 54 rests on the connecting post, and the first fastener passes through the first fastening hole 52 four times to engage with the first mounting hole, thereby locking the mounting bracket 5 onto the protective net 2. Optionally, the first mounting hole is a blind hole to reduce the number of holes and slots on the outer wall of the protective net 2 and improve the aesthetic appearance of the protective net 2.

[0033] like Figure 4 As shown, the protective mesh 2 has a through hole 23 corresponding to the pickup end of the microphone 3. A protective cotton 24 is installed in the through hole 23 to protect the microphone 3 and ensure that the acoustic performance of the microphone 3 meets the standards.

[0034] The pen housing 1 includes a front housing and a rear housing. The front and rear housings are arranged together to form an installation space. The control board is fixed within the installation space. The protective net 2 is fixed to the top or bottom of the pen housing 1. Of course, the protective net 2 can also be set on the side wall of the pen housing 1, depending on the placement of the microphone 3.

[0035] During assembly, the microphone 3 is first fixed to the mounting bracket 5 with foam cotton. Then, the inner wall of the mounting bracket 5 and the protective net 2 are engaged with the clips. After the clips are positioned, the first fastener 4 is used to lock the mounting bracket 5 and the protective net 2. The mounting bracket 5 provides support and limits the microphone 3, ensuring the stability of the microphone 3 installation.

[0036] This invention provides a voice recorder where a microphone 3 is housed within a cavity formed by a mounting bracket 5 and a protective mesh 2. The mounting bracket 5 and the inner wall of the protective mesh 2 engage in a snap-fit ​​mechanism, replacing traditional screw fastening, reducing the number of screws used and improving assembly efficiency. A first fastener 4 passes through a first fastening hole 52 in the mounting bracket 5 to lock the mounting bracket 5 to the protective mesh 2, ensuring a secure connection between the mounting bracket 5 and the protective mesh 2. The voice recorder provided by this invention, through the snap-fit ​​mechanism of the mounting bracket 5 and the protective mesh 2, improves the installation speed of the microphone 3, reduces the number of screws used, decreases the frequency of screw tightening by workers, and simplifies assembly.

[0037] In some embodiments, one of the inner wall of the protective net 2 and the mounting bracket 5 is provided with a slot 21, and the other is provided with a locking block 53. The locking block 53 is engaged with the slot 21.

[0038] like Figure 3 and Figure 5 As shown, the slot 21 is located on the inner wall of the protective net 2. The locking block 53 is located on the mounting bracket 5. During assembly, the locking block 53 is inserted into the slot 21 to connect the mounting bracket 5 and the protective net 2, reducing the number of screws used and saving costs.

[0039] To facilitate locking, the locking block 53 has a guide slope, and the locking block 53 gradually thickens from its end to its root. Compared to a locking block with a uniform thickness, the locking block with a smaller head can be locked into the locking slot 21 more easily and can smoothly enter the locking slot 21 under the guidance of the guide slope.

[0040] Alternatively, the slot 21 can be located on the mounting bracket 5, and the locking block 53 can be located on the inner wall of the protective net 2, as long as it can be ensured that the locking block 53 and the slot 21 can be engaged.

[0041] In some embodiments, the snap-fit ​​position of the mounting bracket 5 and the protective net 2 and the installation position of the first fastener 4 are located on opposite sides of the mounting bracket 5.

[0042] like Figure 2 and 3 As shown, the locking block 53 is located at the end of the mounting bracket 5 furthest from the microphone 3, and the connecting ear 54 is located at the end of the mounting bracket 5 closest to the microphone 3. When the connecting ear 54 abuts against the connecting post and the locking block 53 is engaged in the slot 21, the mounting bracket 5 is vertically constrained and positioned, facilitating the installation of the first fastener 4. The locking block 53 and the connecting ear 54 are located on opposite sides of the mounting bracket 5 to prevent insufficient constraint on the other side of the mounting bracket 5 due to fixation on one side, thereby improving the stability of the connection.

[0043] like Figure 1 and Figure 6 As shown, the voice recorder also includes a second fastener 6. The protective mesh 2 is provided with a second fastening hole 25. The second fastener 6 passes through the second fastening hole 25 to fix the protective mesh 2 to the pen shell 1.

[0044] Specifically, the second fastening hole 25 is located on the top wall of the protective mesh 2. The second fastener 6 can be a fastening screw. The pen shell 1 has a second mounting hole. Both the second fastening hole 25 and the second mounting hole are screw holes. During assembly, the second fastener 6 is sequentially inserted into the second fastening hole 25 and the second mounting hole to lock the protective mesh 2 onto the pen shell 1.

[0045] There can be multiple second fasteners 6. For example, there are two second fasteners 6, which are spaced apart along the length of the top wall of the protective net 2. Both second fasteners 6 are inserted through the protective net 2 and the pen shell 1 to ensure the stability of the connection between the protective net 2 and the pen shell 1.

[0046] In addition, the protective net 2 can also be fixed to the pen shell 1 by adhesive or other means.

[0047] In some embodiments, such as Figure 1 As shown, the mounting bracket 5 has a wire hole 51. A control board is installed inside the pen housing 1. The microphone 3 is electrically connected to the control board via a wire 31. The wire 31 passes through the wire hole 51.

[0048] Specifically, such as Figure 1 As shown, the pen casing 1 has a wire hole 11. One end of the wire 31 is electrically connected to the microphone 3, and the other end passes through the wire hole 51 and the wire hole 11 in sequence to be electrically connected to the control board, thereby realizing the communication connection between the microphone 3 and the control board.

[0049] During assembly, first connect one end of the wire 31 to the microphone 3 electrically, then fix the microphone 3 to the mounting bracket 5, with the wire 31 passing through the wire hole 51. Then, engage the mounting bracket 5 and the inner wall of the protective net 2 with the clips, and after the clips are in position, use the first fastener 4 to lock the mounting bracket 5 and the protective net 2. Next, pass the other end of the wire 31 through the wire hole 11 and connect it electrically to the control board, and fix the protective net 2 to the pen shell 1.

[0050] In some embodiments, such as Figure 2 , Figure 6 and Figure 7 As shown, a sealing gasket 7 is sandwiched between the mounting bracket 5 and the pen shell 1 to seal the wire hole 51.

[0051] Specifically, the sealing gasket 7 has a connection hole. The wire 31 passes through the wire hole 51 and the connection hole in sequence and is electrically connected to the control board. The sealing gasket 7 is located between the mounting bracket 5 and the pen shell 1 to seal the gap between the mounting bracket 5 and the pen shell 1, so as to prevent water from leaking into the pen shell 1 and ensure the waterproof performance of the voice recorder.

[0052] In some embodiments, the sealing gasket 7 is a silicone gasket. In other embodiments, the sealing gasket 7 is an asbestos gasket, a rubber gasket, or a polyurethane gasket.

[0053] In some embodiments, the sealing gasket 7 has a protrusion that surrounds the pen casing 1 circumferentially. The protrusion is pressed together with the pen casing 1 according to a preset interference amount.

[0054] The protrusion is located on the side where the sealing gasket 7 fits against the mounting bracket 5. The user can determine the preset interference amount of the protrusion according to actual needs, such as a preset interference amount of 0.15mm, 0.20mm or 0.25mm, so as to ensure that the sealing gasket 7 has sufficient compression deformation, guarantee the sealing performance at the connection between the mounting bracket 5 and the pen shell 1, and thus ensure the waterproof performance of the voice recorder.

[0055] In other embodiments, such as Figure 7 As shown, the wire hole 51 is a stepped hole with a stepped surface. The sealing gasket 7 has a stepped surface 71. The sealing gasket 7 is inserted and fixed to the wire hole 51. The stepped surface 71 of the sealing gasket 7 abuts against the stepped surface.

[0056] Specifically, such as Figure 7As shown, the diameter of the wire passage hole 51 increases at the opening, forming a stepped hole. The sealing gasket 7 is convex and has a stepped surface 71. The sealing gasket 7 is inserted into the wire passage hole 51, so that the stepped surface 71 abuts against the stepped surface to seal the wire passage hole 51. The positioning sealing gasket 7 is positioned by the abutment of the stepped surface 71 and the stepped surface, and the connection gap between the sealing gasket 7 and the mounting bracket 5 is extended, thereby improving the waterproof effect.

[0057] Alternatively, the sealing gasket 7 can be glued to the wall of the wire hole 51 with waterproof adhesive to improve the waterproof rating of the voice recorder.

[0058] In some embodiments, such as Figure 6 As shown, the protective net 2 has a partition 22 inside. The partition 22 divides the internal space of the protective net 2 into two independent mounting chambers. Each mounting chamber contains a microphone 3 mounted on a mounting bracket 5.

[0059] Specifically, the partition 22 is located in the middle area inside the protective net 2, so that the two mounting cavities are located at opposite ends of the protective net 2. Two mounting brackets 5 are fixed to the walls of the two mounting cavities, forming two receiving cavities. Each receiving cavity houses one microphone 3. Compared to the traditional method of configuring one protective net 2 for each microphone 3 in a recording pen and installing the protective net 2 one by one onto the pen shell 1, this embodiment can install two microphones 3 within one protective net 2, saving costs and avoiding the assembly difficulties caused by the small size of the traditional protective net 2, thus reducing the assembly difficulty of the microphones 3.

[0060] like Figure 6 As shown, the two microphones 3 are separated by a partition 22, which keeps them far apart and prevents interference between them. The two microphones 3 are symmetrically arranged at both ends of the protective net 2, forming a left channel microphone and a right channel microphone, enabling stereo recording by the recorder.

[0061] Optionally, microphone 3 is a directional microphone. A directional microphone can selectively pick up sound from a specified direction and can effectively isolate noise.

[0062] When the voice recorder has two microphones (3), both microphones are directional microphones, ensuring excellent sound pickup quality. Alternatively, the voice recorder can be equipped with an omnidirectional microphone array, such as a six-microphone MEMS microphone array. By combining an omnidirectional microphone array with two directional microphones, the voice recorder can pick up sound from multiple directions and angles, improving sound field reproduction and making it suitable for various recording scenarios, such as meetings, speeches, interviews, or music recording.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
