Abstract

The invention provides a vehicle frequency modulation FM emission system and electronic equipment. The system comprises a signal modulation unit, a power amplifier unit, a boosting unit, and a vertical polarized antenna, the vertical polarized antenna comprises a feeding spring sheet, an antenna body, and a radiator, the feeding spring sheet is coupled to the power amplifier unit and electrically connected to a side surface at one end of the antenna body, the radiation unit is electrically connected to the other end of the antenna body, the radiation unit and the antenna body are arranged at an included angle in the same plane, and the included angle is greater than 90 degrees. According to the vehicle frequency modulation FM emission system, the signal power intensity can satisfy clear playing of an FM receiver in a vehicle, noises and current sounds are prevented, interferences of an FM radio station outside the vehicle can be well hidden, the stability of an FM transmit-receive unit in the vehicle is maintained, the power is limited in the vehicle, and normal operation of other receivers outside the vehicle is not disturbed. The vertical polarized FM emission antenna is advantaged by small size, light weight, convenient built-in, high radiation efficiency, and good directivity.

Description

technical field [0001] The invention relates to automobile electronic technology, in particular to a vehicle-mounted FM transmission system and electronic equipment. Background technique [0002] Car multimedia equipment is more and more widely used in vehicle manufacturing, making people's entertainment in the car richer and making car life more exciting. Most of the human-computer interaction products in the car use Bluetooth to connect, but not all cars are equipped with Bluetooth multimedia devices, and FM radio is a wireless receiving method supported and reserved by various models. [0003] In addition, general vehicle-mounted electronic products only have the function of FM reception and do not have the function of FM transmission, so there is no vehicle network application based on the vehicle-mounted FM receiver. Contents of the invention [0004] The purpose of the present invention is to provide a vehicle-mounted FM transmitting system, aiming at solving the pr...
