What does car mic mean?
1 Answers
Car mic refers to a microphone. In a vehicle, the microphone is primarily used for functions such as Bluetooth call answering and navigation voice playback. The technical term for a microphone is actually 'transducer,' which is a device that converts sound signals into electrical signals through energy conversion, directly derived from the English word 'Microphone' via transliteration. The working principle of a microphone involves sound vibrations reaching the diaphragm of the microphone, which then drives the internal magnet to generate varying electrical currents. These varying currents are then sent to the subsequent sound processing circuit for amplification. Wireless microphones can generally be categorized into three frequency bands: FM band, VHF band, and UHF band.
