TWM320992U - Wireless transmitting relay apparatus for vehicle - Google Patents

Description

M320992 VIII. New description: 【New technology field】 This creation is about a wireless transmission relay device for vehicles, especially a function of judging sound signals, audio and video signals and incoming call signals, and automatically switching according to different signal formats. The car audio playback system is used to broadcast the order of the relay device.

[Prior Art] With the development of electronic products and software industry technology, the original function of the car's internal audio playback system is no longer sufficient, and it faces the situation of replacing the old and new. However, when the vehicle is out of the way, it has built-in car audio playback. System, so the cost of overall elimination is time consuming and time consuming. Therefore, manufacturers have introduced the popular and popular MP3 player with RF modulation technology, so that the personalized music data in the Mp3 player is converted into a radio frequency signal, and then transmitted to the radio frequency antenna of the car audio playback system. The use of the car audio playback system of the eight-player, the existing car auxiliary music car playback system does not have the music playback format, the same can be ... Ρ 3, music format songs or sound. Hand-held mobile phones at the beginning to avoid;; into: = standard control of people can not help but turn into a dangerous car, so there is = combined with a mobile phone and a mobile phone 'when there is a mobile phone call: the amplifier to amplify and receive the radio, to avoid Hold a mobile phone conversation. The popularity of the second hunting video and audio products, there is also the wisdom of the driver to set up to watch video and audio materials
