Description

Portable Audio Mixer Line Interface of Smartphone and Digital Single-Lens Reflex Camera}

The present invention relates to a portable smart phone and a DSLR audio mixer line interface, and more particularly, without a separate mixer and external power supply, MR and other pickup lines or musical instrument sound by a microphone through an audio mixer line interface with a smart phone. It relates to a portable smartphone and a DSLR audio mixer line interface that can record video with DSLR and shoot video without latency at the same time.

Recently, a photo or video is taken while recording external sound through a DSLR or a smart device of a smart phone and a tablet, and uploaded to SNS or YouTube, or stored in a separate internal storage medium.

In such a case, external sound is recorded through a microphone of a DSLR or a smart device of a smart phone and a tablet, but there is a limitation in obtaining a studio-grade high-quality sound source with clean sound quality due to the main characteristics of the device.

In addition, recording and recording facilities have the inconvenience of having to individually record and shoot sound sources and images in a studio to perform a subsequent sync operation between sound sources and images.

In this regard, Korean Open Utility Model Publication No. 2007-0000534 shows the gender of extended voice terminals. However, since the above technology does not have a specific technology for real-time recording and shooting, the mixed song, voice, or accompaniment sound through a separate high-performance external microphone and audio mixer line can be used with DSLR or smart devices of smartphones and tablets. There is a need for a technology capable of performing real-time recording and shooting of sound sources and videos without latency.

The technical problem to be achieved by the spirit of the present invention is to record the sound of musical instruments by the MR and other pickup lines or microphones through an audio mixer line interface without a separate mixer and external power supply, and simultaneously record a video without latency. It is to provide a line interface for portable smartphones and DSLR audio mixers.

In order to achieve the above object, an embodiment of the present invention includes, as an input side, a stereo three-pole plug inserted into an output jack of an MR to transmit accompaniment sound output from the MR; As an input side, a 4-pole or 3-pole condenser microphone for a smart phone connected to a cable extending from the stereo 3-pole plug to record external sound; An earphone jack connected to the cable and configured to output sound output from the stereo 3-pole plug and the condenser microphone to an earphone or a headset; And a four-pole plug connected to the cable and connected to the cable, the stereo three-pole plug and a four-pole plug for transmitting sounds respectively output from the condenser microphone to an input jack of a smartphone; and the stereo three-pole plug and the It provides a portable smart phone and DSLR audio mixer line interface that enables real-time recording of sound by interlocking with a photo or video taken by the smartphone while listening to the sound output from each condenser microphone with the earphone or headset.

Here, as the output side, the stereo three-pole plug and the three-pole plug inserted into the input jack of the DSLR while listening to the sound respectively output from the condenser microphone with the earphone or headset further comprises, the sound is photographed by the DSLR Real-time recording can be performed in conjunction with photos or videos.

In addition, as an input side, further comprising a stereo three-pole jack extending from the cable and inserted into the output jack of the MR to transmit accompaniment sound output from the MR, the earphone jack and the earphone jack and the audio stereo through the cable It can be transmitted to the 4-pole plug or the 3-pole plug.

In addition, a volume controller electrically connected to the cable to adjust a volume of sound output from the stereo 3-pole plug or the stereo 3-pole jack, and a volume controller to adjust the sensitivity of the condenser microphone may be further included.

In addition, the stereo 3-pole plug is composed of a 3.5/3-pole TRS plug, and inserted into the 3.5/3-pole TRS plug so as to be inserted into the 55 jack of the MR to convert a 6.3/3-pole TRS plug into a 55 plug. Can include.

In addition, the stereo three-pole plug is composed of a TRS pin, the earphone jack is composed of a TRSM pin, the four-pole plug inserted into the smartphone is composed of a TRSM pin, and the four-pole plug of the condenser microphone is a TRSM pin. The three-pole plug inserted into the DSLR may be composed of a TS pin, and the stereo three-pole jack may be composed of a TRS pin.
