Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the audio output device that has touch-screen of the present utility model is described in detail.
Fig. 2 shows the schematic diagram that has the audio output device of touch-screen according to of the present utility model.As shown in the figure, audio output apparatus of the present utility model comprises: earphone 4, Mike 2, touch-screen 5, these devices are connected to total data interface 1 by data wire.Figure 2 illustrates two earphones 4, wherein, one is that L channel earphone, one are the R channel earphone, can expect, also can only comprise an earphone.In addition, also wire clamp 2 can be set on the data wire, data wire be attached on the outer attachment of audio output device with convenient.
In audio output device of the present utility model, can carry out various operations to mobile phone by operation touch-screen 5, make that the audio output device function is abundanter, check note, call and also can reduce the radiation of mobile phone by touch-screen human body.
Fig. 3 shows the interface schematic diagram that has the audio output device of touch-screen according to of the present utility model.As shown in the figure, integrated a plurality of data-interfaces on the total data interface 1, these data-interfaces comprise: touch screen controller interface (SCL, SDA, PENIRO*, GND), display interface device (CS, WR, RD, RS, DATA, backlight, POWER, GND), Mike's interface (MIC, MIC_DET), earphone left and right acoustic channels interface (HPH_L, HPH_R), wherein, shared POWER interface of touch screen controller and display and GND interface.Each interface on the total data interface 1 is connected with the corresponding interface of CPU is adaptive, wherein, touch screen controller interface SCL is connected to the communications serial interface I2C of CPU, and touch screen controller interface SDA is connected to another communications serial interface I2D of CPU.
Need to prove, though word and the word abbreviation expression in English of above-mentioned interface, all be sanctified by usage with these words or the word represented interface of abridging, and the implication of its qualification is clearly to those skilled in the art, can not cause ambiguity.For example, POWER represents power interface, and GND represents interface of the ground wire.
Fig. 4 shows the touch-screen input system.As shown in Figure 4, touch-screen 5 comprises touch screen controller 51 and touches detection part 52, touch the screen (not shown) front that detection part is installed in display, be used to detect user touch location, and deliver to touch screen controller 51, the main effect of touch screen controller is to receive touch information from touching detection part, and convert it to contact coordinate, give and the CPU (baseband processor of mobile phone just) of mobile phone, display can receive the order that the CPU of mobile phone sends and be carried out again.Wherein, the touch-screen control chip adopts the TSC2007IYZGR chip of TI company, the LCDs control chip adopts ILI9325DS, and the touch-screen detection part is generally by two-layer transparent resistive conductor layer, form at the separator between the two resistive conductor layers and this three part of electrode of being electrically connected on each resistive conductor layer.
