Description

Technical Field

[0001] The invention belongs to the technical field of movie dubbing, and in particular relates to a movie dubbing device. Background Art

[0002] Movie dubbing is the process of adding sound to a film, which not only adds a lot of environmental sounds, but also includes verbal dialogues between multiple characters. Currently, in order to ensure that the dubbing effect is more realistic and natural, most dubbing work is done in a professional dubbing studio using professional microphones to reduce the impact of noise on recording.

[0003] When recording the character's entrance dialogue, due to the needs of the plot, it is necessary to use two microphones in different positions, one far and one near, to record simultaneously to achieve the effect of sound from far to near. When recording the sound on one side, in order to ensure that the dubbing effect is more realistic and natural, the microphone needs to be moved to the side of the sound point for recording. This requires frequent adjustment of the positions of multiple microphones according to requirements during recording, which greatly increases the dubbing time. At the same time, the current microphones cannot directly simulate the effect of listening underwater. Therefore, after completing the sound recording, it needs to be post-processed using software, which is not convenient for actual use. Summary of the invention

[0008] Preferably, an airbag is fixedly mounted on the top surface of the base plate, the airbag is away from the rotating plate, and the airbag is located directly below the pedal.

[0009] Preferably, a polyoxymethylene strip is fixedly mounted on one end of the convex strip away from the side plate, and the polyoxymethylene strip is in contact with the inner wall of the annular groove and the spiral groove.

[0010] Preferably, extension plates are fixedly installed on both sides of one end of the rotating plate away from the rotating plate, the extension plate is away from the bottom plate, and the length of the extension plate is greater than the length of the mounting plate, a U-shaped frame is fixedly installed on one side of the extension plate close to the mounting plate, the U-shaped frame is away from the rotating plate, and the opening of the U-shaped frame faces the mounting plate, and a U-shaped water bag is fixedly installed on the inner wall of the U-shaped frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The present invention is provided with a rotating plate, a mounting plate and a rotating shaft, etc. When in use, the voice actor only needs to press down the pedal with his foot, so that the rotating plate rotates between the two side plates under the action of the rotating shaft, forcing the two microphones fixed on the mounting plate to rotate around the rotating shaft as the center of the circle under the linkage of the rotating plate, so that one of the two microphones gradually approaches the voice actor and the other gradually moves away from the voice actor, thereby quickly adjusting the position of the microphones so that the subsequent dubbing can achieve the effect of sound from far to near.

The rotating shaft gradually tilts upward under the action of the rotating shaft. At this time, the convex strip on the positioning plate moves from the annular groove to the inside of the spiral groove. As the rotating plate rotates, the convex strip also slides inside the spiral groove, thereby driving the rotating shaft to rotate on the rotating plate through the magnetic bearing, forcing the mounting plate at the end of the rotating shaft to start rotating, adjusting the positions of the two microphones, and finally moving the two microphones to the two sides of the voice actor, thereby quickly adjusting the position of the microphones so that the subsequent dubbing can achieve the effect of single-sided sound.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 3As shown, the present invention provides the following technical solution: a movie dubbing device includes a bottom plate 6, two side plates 7 are symmetrically installed on the top surface of the bottom plate 6, a rotating plate 8 is arranged between the side plates 7, and rotating shafts 5 are symmetrically installed at the lower parts of both sides of the rotating plate 8. The rotating shafts 5 are used for the rotational connection between the side plates 7 and the rotating plates 8, and a through hole 13 is opened on the rotating plate 8, the through hole 13 is far away from the bottom plate 6, and the interior of the through hole 13 is movably connected to the rotating shaft 12 through a magnetic suspension bearing 14, and one end of the rotating shaft 12 is fixedly installed with a mounting plate 1, and the mounting plate 1 is installed. A clamping plate 4 is symmetrically installed on one side of the plate 1 away from the rotating plate 8, and the clamping plate 4 is used to clamp and fix the microphone. A pedal 16 is fixedly installed on the end of the rotating plate 8 close to the bottom plate 6. The pedal 16 is kept vertical to the rotating plate 8, and the pedal 16 is located below the mounting plate 1. The two side plates 7 are fixedly connected by an iron plate 17. The height of the iron plate 17 is less than the height of the side plate 7, and the iron plate 17 is away from the bottom plate 6. The rotating plate 8 is located between the iron plate 17 and the mounting plate 1, and the iron plate 17 and the rotating plate 8 are movably connected by a square spring 15.

[0024] Through the above technical solution: during recording, the dubbing staff can step on the pedal 16 to move it downward, thereby driving the rotating plate 8 to rotate between the two side plates 7 through the rotating shaft 5, so that the distance between the rotating plate 8 and the iron plate 17 gradually increases, and then the square spring 15 is stretched synchronously. Since the mounting plate 1 is fixed to the rotating plate by the interlocking connection between the rotating shaft 12 and the magnetic suspension bearing 14, the mounting plate 1 also starts to rotate with the rotating shaft 5 as the rotation proceeds, so that two microphones that were originally at the same distance from the dubbing staff, one is closer to the dubbing staff, and the other is farther away from the dubbing staff. If dubbing is performed while rotating, the effect of going from far to near can be simulated, and there is no need to adjust the position of the microphone separately, which reduces the dubbing time and improves the dubbing efficiency. After completing such dubbing, the dubbing staff only needs to release the pedal 16 and stop pressing down. At this time, the square spring 15 begins to shrink under the action of its own elastic force, thereby driving the rotating plate 8 to rotate in the opposite direction on the rotating shaft 5, shortening the distance between the rotating plate 8 and the iron plate 17, and when the rotating plate 8 is perpendicular to the bottom plate 6 again, the effect of automatic reset is achieved.

[0025] And because the rotating shaft 5 is installed at the lower part of the side wall of the rotating plate 8, it is far away from the microphone above, which greatly reduces the problem of small noise generated by the rotation of the rotating shaft 12 during actual use, which ultimately affects the dubbing quality.

[0026] In addition, since the microphone is clamped and fixed on the mounting plate 1 by the clamping plate 4, when dealing with different types of dubbing needs or dubbing actors with different timbres, different types of microphones can be quickly replaced by plugging and unplugging to ensure that the final dubbing quality is not affected.

[0027] Furthermore, positioning plates 18 are symmetrically installed on the top of the iron plate 17. The positioning plates 18 are located on both sides of the rotating shaft 12, and a convex strip 19 is fixedly installed on the side of the positioning plate 18 close to the rotating shaft 12. An annular groove 23 and a spiral groove 11 are provided on the side of the rotating shaft 12 away from the mounting plate 1. The annular groove 23 is located between the rotating plate 8 and the spiral groove 11. One end of the spiral groove 11 is connected to the annular groove 23. The convex strip 19 is embedded in the inside of the annular groove 23. A polyformaldehyde strip 21 is fixedly installed on the end of the convex strip 19 away from the side plate 7. The polyformaldehyde strip 21 is in contact with the annular groove 23 and the inner wall of the spiral groove 11.

[0028] Please refer to Figure 1-Figure 5 When recording the sound on one side, the dubbing staff still only needs to step on the pedal 16 to rotate the rotating plate 8 between the two side plates 7 through the rotating shaft 5. As the inclination angle of the rotating plate 8 increases, the end of the rotating shaft 12 away from the rotating plate 8 gradually rises synchronously, which makes the convex strip 19 on the positioning plate 18 also slide inside the annular groove 23 until the convex strip 19 is embedded in the arc groove and squeezes the inner wall of the arc groove as the rotating shaft 12 rises, driving the rotating shaft 12 to rotate on the rotating plate 8 through the magnetic bearing 14, and the rotation of the rotating shaft 12 also synchronously drives the mounting plate 1 at its end to start rotating, so that the microphone fixed on the mounting plate 1 through the clamping plate 4 gradually rotates to the two sides of the dubbing staff, and then the microphone position is quickly adjusted, so that the subsequent dubbing can achieve the effect of single-sided sound.

[0029] In addition, in actual use, the airbag 22 can be repeatedly pressed to make the convex strip 19 repeatedly move back and forth on the spiral groove 11, forcing the mounting plate 1 to be in the process of rotation. If dubbing is performed at this time, the airflow sound generated by the rotation of the microphone can be used to simulate the effect of speaking on a windy day.

[0030] The polyoxymethylene strip 21 installed at the end of the convex strip 19 isolates the convex strip 19 from direct friction with the spiral groove 11 and the inner wall of the annular groove 23, thereby reducing the noise generated by the friction and the recording effect when simulating speaking in a windy day.

[0031] Furthermore, extension plates 2 are fixedly installed on both sides of one end of the rotating plate 8 away from the rotating plate 8, the extension plate 2 is away from the bottom plate 6, and the length of the extension plate 2 is greater than the length of the mounting plate 1, a U-shaped frame 10 is fixedly installed on the side of the extension plate 2 close to the mounting plate 1, the U-shaped frame 10 is away from the rotating plate 8, and the opening of the U-shaped frame 10 faces the mounting plate 1, a U-shaped water bag 3 is fixedly installed on the inner wall of the U-shaped frame 10, an airbag 22 is fixedly installed on the top surface of the bottom plate 6, the airbag 22 is away from the rotating plate 8, and the airbag 22 is located directly below the pedal 16, and a sound receiving port 24 is opened on the U-shaped frame 10, and the sound receiving port 24 is located on the outer wall of the extension plate 2 on one side away from the U-shaped frame 10.

[0032] Please refer to Figure 1-Figure 4 : When recording the effect of listening underwater, the dubbing staff needs to step deeply on the pedal 16 to drive the rotating shaft 12 to drive the mounting plate 1 to rotate until the rotating plate 8 covers the extension plate 2. At this time, the sound receiving end of the microphone fixedly installed on the mounting plate 1 is embedded in the interior of the U-shaped frame 10, and the U-shaped water bag 3 is wrapped by the U-shaped water bag 3 on the inner wall of the U-shaped frame 10, and the sound receiving port 24 opened on the U-shaped frame 10 allows the sound to directly contact the U-shaped water bag 3, eliminating the influence of the material thickness of the U-shaped frame 10 on the recorded sound. At this time, when dubbing is performed, the sound emitted by the dubbing staff contacts the U-shaped water bag 3 through the sound receiving port 24, and finally passes through the U-shaped water bag 3 and is recorded by the sound receiving end of the microphone, thereby simulating the effect of listening underwater.

[0033] See also Figure 1-Figure 4 As shown, the mounting plate 1 is arranged inside the circular ring 20, and both ends of the mounting plate 1 are fixedly connected to the inner wall of the circular ring 20. A plurality of slots 9 are evenly spaced apart on one side of the circular ring 20 away from the rotating plate 8, and the circular ring 20 is located between two U-shaped frames 10.

[0034] Please refer to Figure 1-Figure 2 and Figure 4 : The setting of the circular ring 20 not only increases the rotation stability of the mounting plate 1, but also allows other microphones to be clamped and fixed in the slots 9 on the circular ring 20. By installing multiple microphones at different positions, the sound produced by the dubbing staff can be collected by the microphones at multiple positions, achieving the effect of recording stereo sound.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
