Description

Technical Field

[0001] The utility model relates to the technical field of microphones, in particular to a holographic microphone. Background Art

[0002] Nowadays, the microphones widely used for sound collection in recording studios can be divided into two categories, one is the dynamic microphone, and the other is the condenser microphone. The dynamic microphone is the main form of most dynamic microphones today. It drives the coil on it to vibrate through the vibration of the diaphragm on the microphone head, so as to cut the magnetic flux lines of the magnetic field in the microphone to form an electric current to record the sound information. There are two metal plates in the condenser microphone head, one of which is coated with an electret film and grounded, and the other plate is connected to the gate of the field effect transistor. A diode is connected between the gate and the source. When it is vibrated, the distance between the two plates will change, causing its capacitance to change and cause the voltage to change, thereby recording the sound information. In general, the voltage microphone has better sensitivity and can collect more delicate sounds. The Ambisonics recording format is a new format that uses four microphones for recording. It is mainly used for panoramic sound recording. Unlike traditional stereo recording, which only collects sound information on one plane, it can not only show the width of the sound field, but also has the height of the vertical axis. With the development of the game industry, 4D movies, VR technology, etc., its usage scenarios are becoming more and more extensive.

[0003] When recording in Ambisonics format, multiple sets of microphones are usually used for recording. Using four or more sets of microphones at the same time is inefficient and inconvenient, so it needs to be improved to make it more convenient to use. Utility Model Content
