Handheld Microphone and Headset
一、Business
“Bright Aviation” provides product supply, after sales services,, technical consultation, spare parts support and other businesses.
二、Overview
1. Handheld microphone and headset are used for voice input auxiliary equipment of VHF radio, remote controller and interphone seat.
2. It is applicable to equipment such as various types of remote controller and VHF radio.
3. Differences between dynamic and capacitive microphones:
(1) Working principle: the dynamic microphone uses the principle of electromagnetic induction, and the acoustic vibration drives the coil to cut the magnetic induction line in the magnetic field to generate an electrical signal. Condenser microphones are based on the charge and discharge principle of capacitors. Acoustic vibration changes the capacitance between the diaphragm and the backplane, thereby generating electrical signals. General
(2) Sensitivity and frequency response: condenser microphones are highly sensitive, capable of capturing fine sound details, and have a wide frequency response (usually flat in the audio range). Dynamic microphones have low sensitivity, insensitive to weak sound, and relatively narrow frequency response range (typical range is about 50hz-15khz).
(3) Power supply requirements: condenser microphones require an external phantom power supply (usually 5-48v) to work. Dynamic microphones are easy to use without external DC power supply. General
(4) Structural durability: dynamic microphone is simple and firm in structure, stable in performance, resistant to falling and manufacturing, and can withstand high sound pressure and harsh environment. The condenser microphone has a complex and precise structure, and the diaphragm is fragile. It is afraid of moisture and falling. It needs careful maintenance.
