Problems solved by technology

In addition, there are a lot of accompaniment music on the Internet, which makes it easy to make singing videos
However, since the accompaniment music is played by the speaker and then recorded by the microphone, the distortion of the audio signal becomes significantly larger, and the frequency response is also significantly worse, and the bass and treble in the accompaniment music are lost a lot; The distance between the two microphones is very close, so that the recorded accompaniment music has almost no stereoscopic effect, and the actual effect is similar to that of monophonic accompaniment.
The actual accompaniment music of the singing video recorded by the above method is very poor
Of course, the automatic accompaniment singing camera system combined with a computer, camera and microphone can also record the singing video of personal high-fidelity accompaniment music, but the accompaniment music must be monitored with headphones when recording, and the sound cannot be played with speakers (even if it can be played with speakers). The sound must be very small, not only the above defects, but also the phenomenon that the volume of the accompaniment music is much smaller than the singing voice), otherwise it will form a positive feedback of the accompaniment music sound and self-excited howling
Therefore, the current personal singing videos on video sites are all recorded by computers, and the singers are singing with headphones (such as the video URL provided by Taobao sellers: http: / / detail.tmall.com / item.htm?spm= a1z0k.1000775.1.13.Nwhtrt&id=13043610870&_u=81m1lca8657), which greatly reduces the image of the singer and makes people feel that this is not a performance
Moreover, the camera cannot automatically focus, and other camera indicators are far from what the camera can compare, and the clarity and other indicators of the recorded video are far inferior to the camera.

Abstract

The invention discloses a camera system for high-fidelity automatic accompanying singing, which comprises a camera, an accompanying sound source MP3, a microphone, a signal processing circuit and a sound playing system, wherein a signal of the accompanying sound source is mixed with a singing signal sent by the microphone through an attenuator circuit and then is sent into the camera for shooting, so that a recorded accompanying music is a high-fidelity stereo and the high distortion of the accompanying music recorded by using the microphone by the camera is overcome; the signal of the accompanying sound source is also sent into the sound playing system and the sound is played through a loudspeaker, so that a singer can sing according to the melody of the accompanying music and the prior defects of ungraceful effect and inconvenience in wearing a headset for recording a singing video by using the camera and the microphone matched with the computer are overcome; and a microphone signal insulating circuit from the microphone to the sound playing system is arranged, so that no self-excitation whistler is generated. The camera system has the advantages of high image-quality performing effect shot in a camera mode and high fidelity of the accompanying music shot in the mode of computer adding the camera and the microphone. The camera system can be applied to the high-fidelity recording of an automatic accompanying singing video.

Description

technical field [0001] The invention relates to a camera system, in particular to a high-fidelity automatic accompaniment singing camera system. Background technique [0002] Nowadays, there are more and more singing lovers at home and abroad, and more and more people record their own singing videos and upload them to major video websites to share with the public, and some people use them in TV talent shows and other activities. When using a video camera for singing video production, if you use pre-recorded accompaniment music instead of a band, it saves time and effort, and you can record on the spot with the camera and accompaniment sound turned on. In addition, there are a lot of accompaniment music on the Internet, which makes it easy to make singing videos. However, since the accompaniment music is played by the speaker and then recorded by the microphone, the distortion of the audio signal becomes significantly larger, and the frequency response is also significantly ...
