high sensitivity microphone head

Unidirectional microphone is an audio device with specific directionality, and its design principle is mainly based on pressure gradient.
Through the small hole behind the microphone cavity, the diaphragm is subjected to countless pressures, and due to the pressure difference in different directions, the microphone has directionality.
This type of microphone is mainly sensitive to sound from one direction, which helps to better capture personal voice without interference from environmental noise.
Unidirectional microphones are mainly divided into heart-shaped directionality and supercardioid directionality. The heart shape points towards the range of the microphone, resembling a heart, hence the name.
The non radiative zone is 180 degrees, which is actually the deepest non radiative zone in the direction
The heart-shaped microphone has a lower impact value in situations where there is a monitoring speaker behind the sound head for playback, such as stage performances.
Super heart-shaped directional microphone with consistent sound frequency, suitable for recording studios, radios, and live performances
However, unidirectional microphones also have some drawbacks, as their users can only receive sound from one direction. If the motion or position is unstable, sound may appear
Inconsistent or disturbed situations. In addition, unidirectional microphones cannot receive surround sound, so in scenes where 3D or spatial sound effects need to be simulated, performance may be poor.
