Description

Technical Field

[0001] The invention relates to the technical field of recording, in particular to a high-fidelity vocal recording device. Background Art

[0002] High-fidelity recording, also known as high-fidelity recording technology, refers to the use of a series of technical means to restore the original characteristics of the sound, such as the frequency range, dynamic range, and time characteristics, as realistically as possible, so that the listener can feel the same or similar auditory experience as the scene. The core of high-fidelity recording lies in the accurate capture, processing and restoration of audio signals. High-fidelity recording requires that the frequency range of the audio signal is as wide as possible, generally requiring it to reach 20Hz~20kHz. This range includes all the sounds that the human ear can hear, including bass, mid-range and treble;

[0036] The surface of the transmission shaft 19 is slidably connected with a movable sleeve 20, and the movable sleeve 20 is connected to a limiting shaft 21 on both symmetrical sides. A sliding groove 23 is provided on the inner wall of the movable sleeve 20, and the surface of the limiting shaft 21 is slidably connected to the inner wall of the sliding groove 23.

[0038] When the transmission shaft 19 is located at the upper part of the convex inner wall of the movable sleeve 20, the first limit blocks 24 on both sides of the transmission shaft 19 are clamped on the side of the movable sleeve 20, and when the transmission shaft 19 moves, the movable sleeve 20 can be driven to move; when the transmission shaft 19 is located at the lower part of the convex inner wall of the movable sleeve 20, the first limit blocks 24 are not in contact with the movable sleeve 20. At this time, the movable sleeve 20 can move freely on the surface of the transmission shaft 19, and the side surfaces of the two first limit blocks 24 are clamped with the upper part of the convex inner wall of the movable sleeve 20. The inner wall of the sliding sleeve 18 is connected with a slider 30, and the inner wall of the moving sleeve 20 is slidably connected to the side of the slider 30, so that the moving sleeve 20 can drive the sliding sleeve 18 to move synchronously, thereby realizing the displacement of the driving gear 6 and the switching of different working modes.

The side of the button is slidably connected to the inner wall of the knob 3, and a through hole is opened on the side of the synchronous shaft 17. The side wall of the moving sleeve 20 is slidably connected to the inner wall of the through hole.

[0039] In the first embodiment, the surface of the rotating shaft 10 is threadedly connected with a moving frame 15, the inner wall of the equipment box 1 is rotatably connected with two rotating disks 13, the sides of the two rotating disks 13 are rotatably connected with connecting rods 14, one end of the two connecting rods 14 is rotatably connected with the side of the moving frame 15, the inner wall of the equipment box 1 is rotatably connected with a rotating box 11, the inner wall of the rotating box 11 is connected with a camera 12, and the centers of the two rotating disks 13 penetrate the inner wall of the equipment box 1 and are connected with the side of the rotating box 11;

[0040] Specifically, when the user rotates the shaft 10, the movable frame 15 threadedly connected to the shaft 10 will move to the right, and the movable frame 15 drives the turntable 13 to rotate through the connecting rod 14, and the turntable 13 drives the rotating box 11 to rotate 180°, so that the camera 12 and the microphone work synchronously, recording the singer while capturing the singer's lip changes.

[0041] In the second embodiment, four slots 29 are formed on the inner wall of the movable sleeve 20, a second spring 26 is connected to the lower end surface of the movable sleeve 20, a second limit block 27 is connected to the bottom end of the second spring 26, a side surface of the second limit block 27 is slidably connected to the side surface of the movable sleeve 20, and a side surface of the second limit block 27 is engaged with the inner wall of one of the slots 29;

[0042] Specifically, after the transmission shaft 19 drives the movable sleeve 20 to move to the left, the second limit block 27 is stuck in the corresponding slot 29 under the action of the elastic force of the second spring 26 itself. Each time the user presses the transmission shaft 19, the movable sleeve 20 can be moved backward once, corresponding to four slots 29 respectively. When the movable sleeve 20 moves to the leftmost slot 29, the user presses the transmission shaft 19 again to drive the movable sleeve 20 to move. The movable sleeve 20 moves to the top of the slot 23 under the restriction of the limit shaft 21 and the slot 23. At this time, the transmission shaft 19 is located at the lower part of the convex inner wall of the movable sleeve 20. Under the action of the elastic force of the fourth spring 28 itself, the movable sleeve 20 can be driven to move smoothly to the right end of the transmission shaft 19 to work again.

[0043] Working principle:

[0044] First, after the user has installed the entire device, the user can flexibly select the desired microphone mode according to the actual situation on site. The device has four gears. Each time the button is pressed, it will switch to a different microphone working mode: the first press activates the ribbon microphone 31; the second press switches to the condenser microphone 4; the third press selects the dynamic microphone 5; the fourth press turns on the three microphones to work together at the same time;

[0045] During operation, the user presses the button, the transmission shaft 19 is forced to squeeze the third spring 22 to shrink it, and the first limit blocks 24 on both sides of the transmission shaft 19 push the movable sleeve 20 to move to the left. When the button is pressed to the bottom, the second spring 26 clamps the second limit block 27 into the clamping groove 29 to limit the movable sleeve 20. At the same time, the movable sleeve 20 drives the sliding sleeve 18 to move synchronously through the slider 30. The sliding sleeve 18 pushes the driving gear 6 to move so that it meshes with the second driven gear 9. After releasing the button, the third spring 22 resets the transmission shaft 19 by its own elastic force.

[0046] At this time, the user rotates the knob 3 clockwise to drive the synchronous shaft 17 to rotate. The synchronous shaft 17 drives the driving gear 6 to rotate clockwise synchronously through the sliding sleeve 18. The driving gear 6 and the second driven gear 9 transmit each other, causing the second rotating plate 2 to rotate 180° counterclockwise, so that the ribbon microphone 31 can work alone. In addition, when the transmission shaft 19 rotates, it drives the rotating shaft 10 to rotate clockwise, and the moving frame 15 threadedly connected to the rotating shaft 10 moves rightward accordingly. The moving frame 15 drives the turntable 13 to rotate through the connecting rod 14, and the turntable 13 further drives the rotating box 11 to rotate 180°, so that the camera 12 and the ribbon microphone 31 are synchronously deployed, so that the singer's lip shape changes can be captured while recording the singer.

[0047] When the user presses the button four times in succession, the sliding sleeve 18 drives the driving gear 6 to move and mesh with the three first driven gears 8. At this time, the user turns the knob 3 clockwise to drive the first rotating plate 7 and the second rotating plate 2 to rotate 180° counterclockwise through the first driven gear 8, so that the three microphones can work at the same time;

[0048] After the work is completed, the user presses the transmission shaft 19 again to drive the movable sleeve 20 to move. Under the restriction of the limit shaft 21 and the slide groove 23, the movable sleeve 20 moves to the top of the slide groove 23. At this time, the transmission shaft 19 is located at the lower part of the convex inner wall of the movable sleeve 20. The fourth spring 28 drives the movable sleeve 20 to move smoothly to the right end of the transmission shaft 19 by its own elastic force. The equipment can be put back into work at any time, and the entire operation process is completed.

[0049] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
