Detailed Description
The invention is further illustrated with reference to the following figures and examples:
the first embodiment is as follows:
in the first embodiment shown in fig. 1, the dynamic special effect camera comprises a speaker-like base body, the speaker-like base body comprises a base 11 and a speaker-like frame 12 in front of the base, and a tensioned rubber film 13 is covered in front of the speaker-like frame 12; a section of bobbin 14 is axially connected to the center of the rubber film 13, and an audio coil 15 is wound on the bobbin 14; an annular permanent magnet 16 facing the audio coil 15 is arranged in the base 11; the audio coil 15 is electrically coupled to an output of an audio module in the base 11; the input end of the audio module is coupled to the microphone 2 on the base 11; the center of the rubber membrane 13 is also provided with a camera 3 facing the front of the speaker frame 12, and the camera 3 is coupled to a video module in the base 11.
In the dynamic special-effect camera, the audio module and the video module are integrated on the same circuit board 4. The audio module includes a filter module, which filters out the medium-high frequency component in the audio collected by the microphone 2, and outputs the low-frequency component to the audio coil 15, so that the rubber membrane 13 vibrates as much as possible with the rhythm sound of the live music, and the rhythm sound is prevented from finely vibrating (generally, the rhythm sound is contained in the low-frequency component and has a large amplitude).
In this embodiment, a hard disc 5 is disposed at the center of the rubber film 13, and the camera 3 is disposed on the hard disc 5. The microphone 2 is directed towards the rear of the base.
When the dynamic special-effect camera in the first embodiment is used for shooting in the field, the microphone 2 collects the live music, and the change of the live music is converted into the vibration of the camera 3 through the rubber film 13, so that the picture shot by the camera 3 has a dynamic effect harmonious and consistent with the live music.
Example two:
in the second embodiment shown in fig. 2, the dynamic special effect camera includes a speaker-like base body, the speaker-like base body includes a base 11 and a speaker-like frame 12 in front of the base, and a tensioned rubber film 13 is covered in front of the speaker-like frame 12; a section of bobbin 14 is axially connected to the center of the rubber film 13, and an audio coil 15 is wound on the bobbin 14; an annular permanent magnet 16 facing the audio coil 15 is arranged in the base 11; the audio coil 15 is electrically coupled to an output of an audio module in the base 11; the input end of the audio module is coupled to the microphone 2 on the base 11; a lens 6 is further arranged in the center of the rubber film 13, a camera 3 which is opposite to the lens 6 is fixed in the center of the bottom of the speaker-like frame 12, and the focal length of the lens 6 is far greater than the distance from the lens 6 to the camera 3, so that the camera 3 can see upright images with small deformation; the camera 3 is coupled to a video module within the base 11.
In the first embodiment, the audio module and the video module are integrated on the same circuit board 4. The audio module includes a filtering module, which filters the medium-high frequency component in the audio collected by the microphone 2 and outputs the low frequency component to the audio coil 15.
In addition, in the second embodiment, the lens 6 is disposed in the center of the rubber film 13 through a detachable structure, and after the lens 6 is detached, the center of the rubber film 13 is an open circular hole, so that the camera 3 can directly face a shooting site through the circular hole; therefore, when special effect pictures are not needed, the lens 6 can be removed, and the camera 3 can directly shoot the scene. In the second embodiment, the detachable structure is a sleeve structure 61, wherein a section of the fixed sleeve is fixed at the center of the rubber film 13, the other section of the movable sleeve matched with the fixed sleeve is sealed with the lens 6, and the movable sleeve is inserted into and pulled out of the fixed sleeve.
When the dynamic special-effect camera in the second embodiment is used for shooting in the field, the microphone 2 collects the live music, and the live music is changed and converted into the vibration of the lens 6 through the rubber film 13, so that the incident light angle of the camera 3 vibrates along with the music, and the picture shot by the camera 3 has a dynamic effect harmonious and consistent with the live music.
Compared with the first embodiment, the camera 3 in the second embodiment is always kept in a static state, so that the performance of the camera 3 is more stable, and a camera with higher performance (larger volume and weight) can be adopted without worrying about causing burden on the rubber film 13. The rubber film 13 vibrates back and forth along the axial direction, so that the visual field change is limited in the back and forth vibration process of the camera 3 in the first embodiment, and the dynamic effect of the shot picture is limited; in the second embodiment, even if the front-back displacement distance of the lens 6 is small, the incident light reaching the camera 3 will generate a large positional deviation due to the optical refraction phenomenon, thereby forming a strong dynamic effect.
In addition, it is worth mentioning that the similar loudspeaker base body and the similar loudspeaker frame in the first and second embodiments; so called primarily because its structure is substantially identical to the basic structure of a conventional loudspeaker. In the present invention, since the diaphragm is not desired to generate sound to avoid the positive feedback squeaking phenomenon with the microphone 2, the rubber film 13 is adopted as the diaphragm, so that the volume of the loud speaker can be limited to an extremely low level.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
