Abstract

The utility model relates to a vehicle audio device with a USB interface. One port of the audio device is arranged by the perforating method with a USB interface socket; the interior of a casing body has a circuit board containing a USB control interface unit, one end of which electrically connects with the USB interface socket, so that a USB device can be inserted for data transmission or power acquisition.

Description

Audio apparatus for vehicle with USB interface

Technical field

The utility model relates to a kind of audio apparatus for vehicle with USB interface, is meant that especially its shell has a port from its pedestal inboard and wears usb socket, so that the USB device can insert and carry out transfer of data or power supply draws.

Background technology

Since industrial revolution first time watt invention steam engine, except that having driven the auto industry prosperity in more than 100 year, automobile also becomes the indispensable vehicles of human lives, carries people and arbitrarily runs everywhere.And the most glittering star is exactly computer undoubtedly in the second industrial revolution, change the human lifestyle of many decades backward, from then on the human lives enters into numeral by simulation, the industrial revolution for the third time can be rated as network revolution, the mankind begin custom and spread out of data in a large number on networks, and these inventions are no doubt great, but can be easily except that computer and network in conjunction with, basically still keep independently industrial separately kenel, in the mankind live at home, be not easy especially easily with its mutual integration with automobile.

In the actual life, human its car of serious hope has greater functionality, also wishes and one in computer and its work effectively can be connected, and therefore by the automobile audio with USB interface the demand of two side's resources as common interface is just arisen.After this interface was arranged, people can download the MP3 music to the portable MP 3 player with USB interface by the computer automatic network, sent automobile audio to by USB interface and play, and human pilot can the enjoy network music.Also can utilize USB interface to survey the automotive interior situation, condition of the vehicle is stored in the memory with USB interface, deliver in depot's computer and diagnose.Also can utilize communication electric wire connection activation phone, utilize the car sound equipment to answer mobile phone, increase traffic safety as Non-holding by hand type telephone receiver specially for vehicle use with USB interface.As long as the automobile audio that utilization has USB interface just can be arranged in pairs or groups mutually with commercially available multiple product with USB interface.

In addition, people's demand onboard is not unalterable, therefore just has many auto electronic articles for use to produce.Commercially available auto electronic product utilizes that existing cigar lighter is as power supply on the car more, and cigar lighter has following shortcoming as power supply on the car but utilize: 1) the flame-out back of car cigar lighter still has electricity, easily causes danger after the car owner leaves.2) the flame-out back of car cigar lighter still has electricity, and the electronic product that is inserted on the cigar lighter still consumes the electric power of car battery storage, can cause car not have for a long time.3) the car cigar lighter is too far away apart from instrument board, causes the consumer to use inconvenience, and influences attractive in appearance.Because USB interface provides 5V electric power simultaneously, therefore another group safety power supply supply is provided on sound equipment, just can obtain power supply via automobile cigarette lighter.

Summary of the invention

The utility model discloses a kind of audio apparatus for vehicle with USB interface, can make the information products of present most popular USB interface, by being connected mutually with the utility model, to obtain power supply to itself, for example: the digital camera camera of PDA, mobile phone, USB interface, the hard disk of USB interface, and its data or music song be transferred to audio apparatus for vehicle.

Main purpose of the present utility model is by USB interface, to the information products of present most popular USB interface, carries out powering on the car.

Another purpose of the present utility model is can be directly with USB socket, make things convenient for the portable product of USB interface, as: mobile phone, personal digital assistant, portable MP 3 player carries out map file, film, written historical materials or music song and is transferred to audio apparatus for vehicle.

Clearer for the purpose of this utility model and advantage are disclosed, below will describe specific embodiment in detail and conjunction with figs. describes.
