Description

A kind of vehicle-mounted media player

Technical field

The utility model belongs to the electrical application technology field, particularly relates to a kind of vehicle-mounted media player of using on the vehicle such as car and boat of being suitable for.

Background technology

Along with increasing and the expansion of city size of China's size of population, mass transportation facilities has become the indispensable instrument of most people's trips, particularly in big and medium-sized cities, most working people or go out the administrative staff and set up their relationship with mass transportation facilities especially.

Be typically equipped with audio player on the existing mass transportation facilities, can report name of station by means of the audio player driver and conductor when arriving at a station misses the stop to prevent that passenger's mistake from taking advantage of, can also remind passenger's notice while taking a bus in time, as reminding the passenger to do a good job of it handrail at Ackermann steer angle, reminds people is invited guests to be seated when having the old,weak,sick and disabled personnel to get on the bus, thin passageway or the like that allows of reminds people when personnel are more by bus, though this sound report form is familiar with for people but is existed more deficiency, the one, adopt sound to call out the stops and for the passenger who is unfamiliar with riding route, often sit the mistake station easily; The 2nd, along with the prolongation of the public bus network that expansion causes in city, the time that makes the passenger take may be longer, and install the TV equipment on the existing public transit vehicle mostly, can't mediate the sense of fatigue that is produced when the passenger rides; Three to be based on the flowing power of public transit vehicle extremely strong, public transit vehicle has become a position of advertising media or publicity medium in fact, all be manufactured with advertisement poster or picture poster outward as present many car bodies, or carry out the broadcast of advertisement or publicity by the audio player in the car, but this have only sound and do not have the advertisement of image or publicity lacks sensation intuitively, not easily accepted by people.

The more drawback that utilization brought just because of this audio player, on some vehicles, equipped television playing device now, television playing device is to be equipped on the long-distance mass transportation facilities more in fact, this is because passenger's long-term travel easily produces fatigue, eliminate passenger's sense of fatigue by playing some movie and television plays, certainly also can playing advertisements or publicity by television playing device, but, television playing device generally is to adopt the VCD machine to play, it only can play the broadcast effect, when carrying out the broadcast of advertisement or publicity, could play after must producing advertisement or publicity sheet in addition again, and the content change of advertisement or publicity is very fast, thereby caused the inconvenience of making and using, on the other hand, the general volume of television playing device is all bigger, can occupy in the car than large space, make that the interior space that may comparatively crowd originally is more apparent to crowd.

In order to eliminate the some shortcomings part that television playing device brings, now existing a fraction of mass transportation facilities has adopted directly equips computer apparatus on vehicle, come the content of playing advertisements or publicity by computer apparatus, though adopt this kind mode can realize the convenience that advertisement or publicity are made, but exist following deficiency: the one, directly equip host computer and cause volume excessive; The 2nd, disturbance rejection, dustproof, shockproof performance deficiency are particularly aspect shockproof, because pounding of vehicle causes the computer equipment operating cycles to shorten; The 3rd, the repeated use of floppy disk and CD easily makes computer equipment damage quickly; The 4th, the capacity of storage medium is less.

The utility model content

The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of be suitable for using on the vehicle such as car and boat have better disturbance rejection, dustproof a, antihunt action, and big, the whole device volume of storage medium capacity is less, the convenient vehicle-mounted media player of making of content, by cooperating of this vehicle-mounted media player and general television set or computer monitor, can be implemented in the broadcast of car and boat enterprising line number sign indicating number photo and files in stream media such as the report name of station of audio frequency and video, the broadcast of the advertisement of audio frequency and video or publicity content etc.
