Problems solved by technology
[0002] Although the development of car audio and video technology is getting faster and faster, the applicability of car radios is still very wide because drivers need to pay attention to factors such as road conditions, but now a considerable number of car AM / FM radios on cars still use a radio antenna. Because the signal received by the antenna is directional, when the vehicle is moving, due to weak signal or multi-path interference, the driver's listening effect is particularly prone to noise, making the sound quality of the radio relatively poor
[0003] In the existing DVD market, there is no car DVD product that can upgrade the original car's single-antenna radio to dual-antenna radio.

The invention discloses a vehicle-mounted digital video disk (DVD) and a method of achieving motor vehicle double antenna reception. The vehicle-mounted DVD comprises a vehicle-mounted DVD body, wherein a double-antenna reception circuit board is arranged in the vehicle-mounted DVD body, and a first antenna jack connector and a second antenna jack connector are arranged in the vehicle-mounted DVD body. The first antenna jack connector and the second antenna jack connector are respectively connected with the double-antenna reception circuit board. A vehicle-mounted DVD antenna is further arranged outside the vehicle-mounted DVD body. A vehicle-mounted DVD antenna plug is arranged at one end of the vehicle-mounted DVD antenna. The vehicle-mounted DVD antenna plug is connected with the double-antenna reception circuit board through the first antenna jack connector. An antenna plug of an original antenna of the vehicle is connected with the double-antenna reception circuit board through the second antenna jack connector. By the adoption of the vehicle-mounted DVD and the method of achieving motor vehicle double antenna reception, the listen effect under the conditions of weak signal or multipath interference and the like can be improved.
Description
technical field [0001] The invention relates to the field of car audio and video, in particular to a car DVD and a method for realizing car dual-antenna radio reception. Background technique [0002] Although the development of car audio and video technology is getting faster and faster, the applicability of car radios is still very wide because drivers need to pay attention to factors such as road conditions, but now a considerable number of car AM / FM radios on cars still use a radio antenna. Because the signal received by the antenna is directional, when the vehicle is moving, the driver's listening effect is particularly prone to noise due to weak signal or multi-path interference, which makes the sound quality of the radio relatively poor. [0003] And the existing DVD market does not have a vehicle-mounted DVD product that can upgrade the single-antenna radio to the dual-antenna radio for the original car. [0004] Therefore, the prior art still needs to be improved an...
