Abstract

The utility model discloses a 3G (3rd generation) portable wireless router supporting multimedia functions, which comprises a battery charging managing chip, a power supply managing chip, an application processor, a storage device, a 3G module, a WIFI (wireless fidelity) module, a touch screen, an earphone, a USB (universal serial bus) interface and an audio coding/decoding chip. An LCD (liquid crystal display) interface and a touch-panel interface on the application processor are connected with the touch screen and can play a video file stored on a network or stored locally; an audio controller on the application processor is connected with an external audio decoding chip, converts a digital speech signal output by the application processor into an analog speech signal, and then outputs the analog speech signal to an earphone interface or an SPK (storage protection key) interface; and a simple control key circuit is constructed on a GPIO (general purpose input/output) port on the application processor to complete the basic operation to the multimedia functions. By using the 3G portable wireless router supporting the multimedia functions, through resource integration, more functions are achieved with lower cost.

Description

A kind of 3G portable mobile wireless router of supporting multimedia function

Technical field

The utility model is on the basis of 3G portable mobile wireless router, to further expanding of its function, give full play to the multimedia function of application processor in the product, and multimedia function combined with 3G technology, the terminal use can be surfed the web whenever and wherever possible, a kind of brand-new impression of user is given in high-speed downloads, audio frequency and video broadcast etc.The utility model not only can use as a 3G/WIFI router, also can use as a portable 3G multimedia player.

Background technology

No matter the use of wireless router in our life is unit office, the study of enterprises and institutions more and more widely, or the use of personal user's household, and we can see the figure of wireless router.Portable 3G wireless router is based on the router of 3G (Third Generation) Moblie technology.At present, 3 kinds of 3G standards are arranged in the world, all realize commercialization in China.Portable 3G wireless router, volume is little, can carry, being an energy is converted into 3G the Wi-Fi signal, makes up the equipment of Wi-Fi Hotspot whenever and wherever possible, allow periphery comprise the equipment realization multiple users share online of support Wi-Fi such as digital camera, notebook, PSP, mobile phone, for realizing that sharing the 3G wireless network in the WLAN (wireless local area network) provides great convenience, uses very extensive.

So, whether can so portable 3G wireless router just satisfy terminal use's demand? except portable 3G wireless router, are there other modes to set up Wi-Fi Hotspot? answer is sure.Along with the continuous development of consumer electronics, in some handset products, realized the 3G signal is changed into the function of WIFI signal.For example, some high-end smartphones are just supported such function.Present main flow operation system of smart phone such as Symbian, Andriod and WindowsMobile all have this type of software.Present terminal equipment day by day overlaps on function, has three trend substantially: the first, communication and content digitlization gradually; The second, disposal ability strengthens gradually; Three, memory space increases gradually.Terminal equipment presents many network characteristics and multi-functional characteristic.

We should give prominence to for portable product is workability under its situation of movement, but we are not very long at time of really using wireless router in many instances, and also is a relatively fixing occasion when using.Like this, we are in off-mode at just the have to router more time of let us, are a kind of waste to resource really, not as good as the high-end 3G smart mobile phone of buying a support Wi-Fi Hotspot.

Therefore, the product form of portable 3G wireless router is thoroughly changed very urgent, only stay in this simple function of router, will lose more terminal use.Along with the application processor function of using in the 3G wireless router is gradually become strong, make full use of the undeveloped resources on the application processor, tap/dip deep into goes out to be different from the otherness function of other-end product, could really satisfy the needs of terminal client.

Summary of the invention

In the utility model, we are the breach with the multimedia function of application processor, ask different deposit with, not only for the terminal use realizes multiple users share online, in moving process, allow end-user experience simultaneously to the digital multimedia function such as surfing the web, audio frequency and video are browsed at a high speed.

The utility model makes full use of the system resource on the general portable 3G wireless router, utilize the powerful wireless network of 3G module to insert advantage, the large storage capacity of expansion card T card, add simple interfaces such as video and audio frequency, the 3G router of just having formed a support multimedia function powerful, with low cost, realized the perfect adaptation of two kinds of products, dual-use is given the brand-new use experience of terminal use.

The utility model is achieved by the following technical solution:

A kind of 3G portable mobile wireless router of supporting multimedia function, comprise: battery charging management chip, power management chip, application processor, memory, 3G module, WIFI module, touch-screen, earphone, USB interface, audio coding decoding chip, LCD interface on the described application processor is connected with touch-screen with the touch-panel interface, can play the video file of the network storage or local storage; Audio Controller on the application processor connects outside audio decoder chip, and the audio digital signals that application processor is exported is converted into analog voice signal, outputs to earphone interface or SPK interface then; GPIO on the application processor builds simple control key circuit, finishes the basic operation to multimedia function.

In the 3G portable mobile wireless router apparatus of described support multimedia function, WIFI wireless aps unit has realized that data insert in the WLAN (wireless local area network).

In the 3G portable mobile wireless router apparatus of described support multimedia function, the 3G module has realized that operator's 3G network cover data inserts.

In the 3G portable mobile wireless router apparatus of described support multimedia function, USB interface is used for the Virtual Ethernet unit, realizes the access and the system network management function of cable network.

In the 3G portable mobile wireless router apparatus of described support multimedia function, the T card is used for the local file storage, and the memory space of the data in server communal space and multimedia file is provided.

In the 3G portable mobile wireless router apparatus of described support multimedia function, LCD is used for multimedia messagess such as the video, picture, literal of display network storage or local storage; Touch-panel is exactly the touch panel above the touch-screen, and this is that user's operating and controlling interface is user's a operating and controlling interface, reduces the quantity of physical button, and the compact of machine system is provided.
