What does MIC mean on a car?
1 Answers
MIC in a car stands for Microphone. Inside the vehicle, the microphone is primarily used for Bluetooth hands-free calling and navigation voice playback, among other functions. The technical term for a microphone is actually 'transducer,' which is a device that converts sound signals into electrical signals, derived directly from the English word 'Microphone.' Wireless microphones can generally be categorized into three frequency bands, as follows: 1. FM Band: Since FM radios operate between 88-108MHz, and FM band wireless microphones operate above 108MHz, typically between 110-120MHz, FM radio signals do not interfere with FM band wireless microphones. This type of wireless microphone is simple in structure and low-cost, but the sound quality is relatively poor. 2. VHF Band: The VHF band, commonly referred to as the V band, operates between 180-280MHz. Due to its higher frequency, it experiences less interference and uses crystal frequency locking for more stable reception performance. 3. UHF Band: The UHF band, commonly referred to as the U band, operates between 700-900MHz. At such high frequencies, there is almost no interference from other external frequencies. Additionally, U band devices often use surface-mount components, resulting in very stable performance and excellent sound quality.
