[0059] Figure 1 It is a schematic diagram of the structural decomposition of the voice recorder provided by an embodiment of the utility model. Figure 2 It is a partial structural diagram of the voice recorder provided in an embodiment of the utility model.
[0060] See Figure 1 and Figure 2An embodiment of the present invention provides a voice recorder, which includes a frame assembly 10, a lifting assembly 20 and a microphone assembly 30.
[0061] The frame assembly 10 defines the external shape of the voice recorder and serves as the main support for the voice recorder. The frame assembly 10 includes a frame body 11, a display screen 12, and a cover plate 13. The frame body 11 serves as the support skeleton of the voice recorder. The frame body 11 can be a rectangular structure. The frame body 11 has a first side surface and a second side surface that are opposite to each other along the width direction. The display screen 12 is provided on the first side surface and covers the entire first side surface to form a full-screen voice recorder. The cover plate 13 is provided on the second side surface to enclose and fix the battery and achieve sealing of the voice recorder.
[0062] The frame body 11 is provided with an accommodating space. When the cover 13 is covered on the frame body 11 , the cover 13 and the frame body 11 enclose a accommodating cavity 14 with an opening on one side. The lifting assembly 20 can be accommodated in the accommodating cavity 14 .
[0063] The lifting assembly 20 includes a support frame 21 and a lifting module 22. The support frame 21 is plugged into the frame body 11 of the frame assembly 10. The lifting module 22 is set on the frame body 11 of the frame assembly 10 and is used to drive the support frame 21 to perform lifting movements so that the support frame 21 extends in and out of the accommodating cavity 14.
[0064] The microphone assembly 30 includes a directional microphone 31 and a first omnidirectional microphone 32 . The directional microphone 31 is rotatably connected to the support frame 21 . The first omnidirectional microphone 32 is provided in the frame assembly 10 and is located at the matching position between the support frame 21 and the frame assembly 10 .
[0065] When the lifting module 22 drives the support frame 21 to be located in the accommodating cavity 14, the directional microphone 31 and the first omnidirectional microphone 32 are hidden between the frame body 11 and the cover 13 of the frame assembly 10, and will not squeeze the screen space, thereby increasing the screen ratio and meeting the user's high requirements for the screen ratio (such as full screen); moreover, it can prevent dust from falling on the directional microphone 31 and the first omnidirectional microphone 32 to block the sound pickup hole and affect the sound pickup effect of the directional microphone 31 and the first omnidirectional microphone 32. At this time, it is equivalent to the voice recorder being in a non-recording state.
[0066] When the lifting module 22 drives the supporting frame 21 to move, the directional microphone 31 and the first omnidirectional microphone 32 are both exposed from the frame assembly 10, and can synchronously pick up sound to improve the sound pickup effect. At this time, it is equivalent to the voice recorder being in the recording state.
[0067] It should be noted that the voice recorder can also be equipped with a camera function. Specifically, the camera is provided on the back of the voice recorder, specifically, the camera is fixed to a sub-plate, which is fixed near the top of the support frame 21. The surface of the camera is covered with a lens (not numbered in the figure). A corresponding notch 131 is provided above the cover 13 to reveal the camera. The camera is not affected by the movement of the support frame 21 and can be used in both recording and non-recording modes.
[0068] It is understood that the voice recorder provided by the embodiment of the present invention, by providing a lifting assembly 20 in the accommodating cavity 14 of the frame assembly 10, comprises a support frame 21 and a lifting module 22. The support frame 21 is plugged into and matched with the frame body 11 of the frame assembly 10. The lifting module 22 is provided on the frame body 11 of the frame assembly 10 and is used to drive the support frame 21 to perform lifting motion, so that the support frame 21 extends in and out of the accommodating cavity 14. A directional microphone 31 is rotatably connected to the support frame 21, and a first omnidirectional microphone 32 is provided in the frame assembly 10 and is located at the mating position between the support frame 21 and the frame assembly 10.
[0069] When the lifting module 22 drives the support frame 21 to move up and down, the directional microphone 31 and the first omnidirectional microphone 32 are both suitable for being hidden in the accommodating cavity 14 or exposed in the frame assembly 10. When both the directional microphone 31 and the first omnidirectional microphone 32 are hidden in the accommodating cavity 14, that is, when they are hidden between the frame body 11 and the cover 13 of the frame assembly 10, they do not squeeze the screen space, thereby increasing the screen-to-body ratio to meet users' high screen-to-body ratio requirements (such as full-screen). Furthermore, they can prevent dust from accumulating on the directional microphone 31 and the first omnidirectional microphone 32, thereby blocking the sound pickup holes and affecting the sound pickup effect of the directional microphone 31 and the first omnidirectional microphone 32. When the directional microphone 31 and the first omnidirectional microphone 32 are exposed in the frame assembly 10, they can simultaneously pick up sound, thereby improving the sound pickup effect.
[0070] Continue reading Figure 1 In some embodiments of the present invention, the lifting module 22 includes a mounting carrier 221, a driving member 223 and a transmission member 222. The mounting carrier 221 is arranged on the frame body 11 of the frame assembly 10 for mounting the driving member 223 and the transmission member 222. The driving member 223 is arranged on the mounting carrier 221. The driving member 223 can be a driving structure such as a motor that can perform rotational motion. The transmission member 222 is arranged on the mounting carrier 221 to convert the rotational motion of the driving member 223 into linear motion. The transmission member 222 is connected to the output end of the driving member 223, and the support frame 21 is fixedly connected to the transmission member 222.
[0071] When the driving member 223 works and drives the transmission member 222 to move, the transmission member 222 converts the rotational motion of the driving member 223 into linear motion, driving the support frame 21 to rise and fall, so that the support frame 21 extends in and out of the accommodating cavity 14, so that the directional microphone 31 and the first omnidirectional microphone 32 are suitable for being hidden in the accommodating cavity 14 or revealing the frame assembly 10.
[0072] Continue reading Figure 1 In some embodiments of the present invention, the transmission component 222 includes a lead screw 2221, a guide member 2222, and a follower 2223. One end of the lead screw 2221 is connected to the output end of the driver 223, and the other end of the lead screw 2221 is connected to the mounting carrier 221 via a bearing. The guide member 2222 is a rod-shaped structure, fixed to the mounting carrier 221, and arranged parallel to the lead screw 2221. The follower 2223 can be a plate-shaped structure, threadedly engaged with the lead screw 2221, and slidingly engaged with the guide member 2222. The support frame 21 is fixedly connected to the follower 2223 via bolts or screws.
[0073] Because the follower 2223 is restricted by the guide member 2222, it can only move along the axis of the lead screw 2221 and cannot rotate with the lead screw 2221. Therefore, when the driving member 223 is working and drives the lead screw 2221 to rotate, the lead screw 2221 pushes the follower 2223 to move up and down along the extension direction of the guide member 2222, thereby driving the support frame 21 to move up and down, causing the support frame 21 to extend in and out of the accommodating cavity 14, so that the directional microphone 31 and the first omnidirectional microphone 32 can be hidden in the accommodating cavity 14 or exposed from the frame assembly 10.
[0074] It should be noted that a guide rail may be provided on the mounting carrier 221 , and a slider may be provided on the follower 2223 accordingly. The slider and the guide rail may be slidably engaged with each other to provide a guide for the follower 2223 .
[0075] In some embodiments of the present invention, the transmission component 222 may further include a transmission gear and a rack. Specifically, a driving gear is provided at the output end of the driving member 223, so that the transmission gear meshes with the driving gear and the rack, respectively, and the rack is fixed to the support frame 21. When the driving member 223 is in operation, the driving gear rotates, and the driving gear synchronously rotates the transmission gear. The rack causes the support frame 21 to change position, causing the support frame 21 to extend in and out of the accommodating cavity 14, so that the directional microphone 31 and the first omnidirectional microphone 32 can be concealed in the accommodating cavity 14 or exposed from the frame assembly 10.
[0076] Figure 3 This is one of the partial cross-sectional views of the voice recorder provided by an embodiment of the present utility model (non-recording mode). Figure 4This is the second partial cross-sectional view of the voice recorder provided in an embodiment of the present utility model (first recording mode). Figure 5 This is the third partial cross-sectional view of the voice recorder provided in the embodiment of the present utility model (second recording mode).
[0077] See Figures 3 to 5 In some embodiments of the present invention, the voice recorder further includes an angle adjustment assembly 40 movably mounted on the support frame 21. One end of the angle adjustment assembly 40 is rotatably connected to the directional microphone 31, while the other end of the angle adjustment assembly 40 maintains contact with the mounting carrier 221. The angle adjustment assembly 40 moves up and down along with the support frame 21 to change the contact position between the angle adjustment assembly 40 and the mounting carrier 221, thereby achieving angle adjustment of the directional microphone 31.
[0078] The angle adjustment assembly 40 includes an adjustment rod 41 and an elastic member 42. The adjustment rod 41 is a rod-shaped member that extends through the support frame 21. One end of the adjustment rod 41 is pivotally connected to the directional microphone 31 via a hinge, while the other end of the adjustment rod 41 maintains contact with the mounting support 221. The elastic member 42, which can be a spring or other structure, is mounted on the outside of the adjustment rod 41 and located between the support frame 21 and the mounting support 221.
[0079] When the adjustment rod 41 moves up and down with the support frame 21 , the contact position between the other end of the adjustment rod 41 and the mounting carrier 221 changes, so that the adjustment rod 41 moves relative to the support frame 21 to drive the directional microphone 31 to deflect and achieve angle adjustment.
[0080] It should be noted that the support frame 21 may be provided with a support arm (not shown), and the housing (not numbered) of the directional microphone 31 is rotatably connected to the support arm via a pin or other structure. The follower 2223 is fixedly connected to the support frame 21 via bolts. The support frame 21 has a positioning hole (not numbered) defined therein, through which the adjustment rod 41 is inserted.
[0081] In some embodiments of the present invention, in order to improve the structural stability of the angle adjustment assembly 40, the angle adjustment assembly 40 also includes a positioning member 43, which is inserted into the positioning hole on the support frame 21 and has an interference fit with the positioning hole, and the adjustment rod 41 passes through the positioning member 43 and the positioning hole.
[0082] At the same time, a limiting step 411 is provided on the adjusting rod 41, one end of the elastic member 42 abuts the positioning member 43, and the other end of the elastic member 42 abuts the limiting step 411. This arrangement can provide good position positioning for the elastic member 42 and improve the stability of the elastic member 42.
[0083] Continue reading Figures 3 to 5 In some embodiments of the present invention, the mounting carrier 221 includes a base plate 2211, an adjusting portion 2212, and a fixing portion 2213 disposed on the base plate 2211. The adjusting portion 2212 and the fixing portion 2213 are disposed at opposite ends of the base plate 2211. The driving member 223 is disposed on the fixing portion 2213, and the guide member 2222 and the lead screw 2221 are disposed between the adjusting portion 2212 and the fixing portion 2213.
[0084] A first adjusting section 2212 - 1 and a second adjusting section 2212 - 2 are connected to each other on the side of the adjusting portion 2212 . The gap between the first adjusting section 2212 - 1 and the support frame 21 is smaller than the gap between the second adjusting section 2212 - 2 and the support frame 21 .
[0085] When the other end of the adjustment rod 41 is in contact with the first adjustment section 2212-1, the position of the directional microphone 31 remains unchanged; when the other end of the adjustment rod 41 is in contact with the second adjustment section 2212-2, the directional microphone 31 deflects toward the direction of the adjustment portion 2212 to achieve angle adjustment.
[0086] The first adjustment section 2212-1 can be a flat surface, and the second adjustment section 2212-2 can be a curved surface. The other end of the adjustment rod 41 is in surface contact with the adjustment portion 2212, compared to the other end of the adjustment rod 41 in line contact with the adjustment portion 2212. This arrangement can increase the contact area between the adjustment rod 41 and the adjustment portion 2212, thereby improving the stability of the adjustment rod 41 during movement.
[0087] In some embodiments of the present invention, in order to enable the adjusting rod 41 to smoothly transition from the first adjusting section 2212-1 to the second adjusting section 2212-2, or smoothly transition from the second adjusting section 2212-2 to the first adjusting section 2212-1, an arc transition section 2212-3 is further provided between the first adjusting section 2212-1 and the second adjusting section 2212-2.
[0088] Continue reading Figures 3 to 5 In some embodiments of the present invention, the frame body 11 of the frame assembly 10 is provided with a plug-in portion 111 that is plugged into the support frame 21. The plug-in portion 111 is provided with a first sound pickup channel 112. The first sound pickup channel 112 can be at least one through hole. The first omnidirectional microphone 32 is provided on the plug-in portion 111 and is located at the position where the first sound pickup channel 112 is located.
[0089] When the supporting frame 21 moves up and down to expose the first sound pickup channel 112 , the first omnidirectional microphone 32 can pick up sound through the first sound pickup channel 112 .
[0090] Continue reading Figures 3 to 5In some embodiments of the present invention, the microphone assembly 30 also includes a second omnidirectional microphone 33, and a second sound pickup channel 211 is provided on the supporting frame 21. The second omnidirectional microphone 33 is provided on the supporting frame 21 and is located at the position where the second sound pickup channel 211 is located, and the position height of the second sound pickup channel 211 is lower than the position height of the sound pickup channel of the directional microphone 31.
[0091] When the supporting frame 21 is not fully extended from the accommodating cavity 14 , only part of the sound pickup channel of the directional microphone 31 is exposed for sound pickup, while the second sound pickup channel 211 is still hidden in the accommodating cavity 14 , and the second omnidirectional microphone 33 cannot pick up sound through the second sound pickup channel 211 .
[0092] The sound pickup channel of the fixed-direction microphone 31 can be understood as the sound pickup hole on the cover of the fixed-direction microphone 31 .
[0093] It should be noted that the support frame 21 includes a main body and a matching part (not numbered in the figure). The interior of the main body is provided with a accommodating groove that can accommodate the installation carrier 221. The matching part is symmetrically arranged on both sides of the main body. The matching part is plugged into the plug-in part 111, and an installation space for installing the directional microphone 31 is formed between the matching part and the main body.
[0094] Continue reading Figures 3 to 5 In some embodiments of the present invention, the voice recorder further includes a circuit board 15, which is disposed between the frame body 11 and the cover 13, and the circuit board 15 is electrically connected to the directional microphone 31, the first omnidirectional microphone 32, and the second omnidirectional microphone 33, respectively.

Figure 7 This is one of the side views of the voice recorder provided by an embodiment of the present utility model (non-recording mode). Figure 8 This is the second main view of the voice recorder provided by the embodiment of the present utility model (first recording mode). Figure 9 This is the second side view of the voice recorder provided in the embodiment of the present utility model (first recording mode). Figure 10 This is the third main view of the voice recorder provided by the embodiment of the present utility model (second recording mode). Figure 11 This is the third side view of the voice recorder provided in the embodiment of the present utility model (second recording mode).
[0096] See Figure 3 、 Figure 6 and Figure 7 , Figure 3 The cover 13 is hidden in the recording pen of the present invention. In the non-recording mode:
[0097] The first omnidirectional microphones 32 located on the left and right sides of the frame body 11, the directional microphones 31 located on the left and right sides of the support frame 21, and the second omnidirectional microphone 33 located on the front of the support frame 21 are all concealed within the accommodating cavity 14 defined by the frame body 11 and the cover 13. At this point, the follower 2223 is located at the very bottom of the lead screw 2221, the support frame 21 is not extended, the adjustment rod 41 of the angle adjustment assembly 40 remains in contact with the first adjustment section 2212-1 of the adjustment portion 2212, the elastic member 42 is compressed, and the directional microphone 31 is in a nearly vertical position.
[0098] See Figure 4 、 Figure 8 and Figure 9 , Figure 4 The cover 13 is hidden in the recording pen. In the first recording mode, the recording pen provided by the embodiment of the utility model:
[0099] When the driving member 223 (such as a stepping motor) receives an upward command, the driving member 223 works to drive the lead screw 2221 to rotate, and the lead screw 2221 pushes the follower 2223 to move upward along the extension direction of the guide member 2222, thereby driving the support frame 21 to move upward, so that the support frame 21 extends a certain height from the accommodating cavity 14, and the sound pickup channel of the directional microphone 31 is exposed to achieve directional sound pickup; at the same time, the first sound pickup channels 112 hidden on both sides of the frame body 11 are exposed, and the first omnidirectional microphones 32 arranged on the left and right sides of the frame body 11 can achieve omnidirectional sound pickup through the exposed first sound pickup channels 112.
[0100] At this time, although the adjustment rod 41 rises a distance along with the support frame 21, the end of the adjustment rod 41 still maintains contact with the first adjustment section 2212-1, the elastic member 42 still maintains the compressed state, and the position of the directional microphone 31 remains unchanged.
[0101] Among them, the first recording mode of the voice recorder provided by the embodiment of the utility model is suitable for scenarios with a close sound pickup range, such as news interviews, etc., maintaining the directional sound pickup of the directional microphone 31, and turning on the first omnidirectional microphones 32 on the left and right sides to pick up sound, using low power consumption.
[0102] See Figure 5 、 Figure 10 and Figure 11 , Figure 5 The cover 13 is hidden in the middle. The recording pen provided by the embodiment of the utility model is in the second recording mode:
[0103] The driving member 223 continues to rotate, driving the lead screw 2221. The lead screw 2221 pushes the follower 2223 to continue moving upward along the extension direction of the guide member 2222, thereby driving the support frame 21 upward, causing the support frame 21 to gradually fully extend from the accommodating cavity 14. At this time, the adjustment rod 41 of the angle adjustment assembly 40 transitions from the first adjustment section 2212-1 to the second adjustment section 2212-2. The elastic member 42 resumes its elastic deformation, pushing the adjustment rod 41 to move, thereby pulling the cover of the directional microphone 31 to deflect toward the middle position near the adjustment portion 2212, thereby adjusting the sound pickup angle and range of the directional microphone 31. This automatically expands the relative angle of the directional microphone 31 and improves the sound pickup coverage.
[0104] At the same time, the second sound pickup channel 211 provided on the front of the support frame 21 is fully exposed, and the second omnidirectional microphone 33 can perform omnidirectional sound pickup through the second sound pickup channel 211. In other words, at this time, the voice recorder can achieve simultaneous sound pickup by four omnidirectional microphones and two directional microphones 31 with adjustable angles. The omnidirectional microphones have better omnidirectional performance and better noise reduction capabilities, making them suitable for near-field sound pickup. The directional microphones 31 have good directional sound pickup effects and can pick up sounds at a distance, making them suitable for far-field sound pickup. The two microphones work together to improve the sound pickup efficiency of the voice recorder.
[0105] Among them, the second recording mode of the voice recorder provided by the embodiment of the utility model is suitable for scenes with a long pickup range, such as teaching scenes.
