Abstract

The utility model relates to the technical field of car audio, in particular to the structural development for the car audio touch control screen. A touch control screen is positioned on the car audio body and composes a touch circuit board with a touch inducting chip. The touch circuit board is connected with the central control chip of the audio through the interface and is provided with a LCD display equipped with a transparent inductive touch board and a transparent insulating panel is installed on the LCD display. The car audio proposed in the utility model is of the touch screen type key control structure, so that the user can directly touch or approach the touch control screen to realize the application. Because of no mechanical parts, non-wearing, reliable and durable application and random designable super display patterns further reinforce the desirable appearance and fashionable sense of the utility model.

Description

A kind of automobile audio

Technical field

The utility model relates to the automobile audio technical field, specifically relates to a kind of automobile audio of the architecture advances to the automobile audio panel.

Background technology

Along with science and technology development, the raising of people's living standard, automobile has been the requisite walking-replacing tools of people as the daily vehicles.Along with increasing of private car, people are also more and more higher to the requirement of automobile, are that the outward appearance of automobile or the setting in automotive interior space, little sound equipment in car all are the fastidious objects of user vehicle.Not only require good product performance, the reliable in quality of automobile influence, and also very high to the requirement of aspects such as automobile audio outward appearance, visual effect and hommization operation.

But the guidance panel of existing automobile audio is metal decking or physical construction formula panel mostly, this class mechanical type button control panel, it is realized by mechanical connecting structure that mainly repeatedly use is easy to generate aging, wearing and tearing, situations such as loose contact, and be subjected to the restriction of structural member easily, because the connection that mechanical button polygamy closes structural member is operated, when structural member unreasonable, when not firm, processing ease lost efficacy, and general access times are no more than 200,000 times.Given this, on the market the electronic product of the operating board structure that touches structure occurred having, as had the instrument and meter that touches control panel, air-conditioning of band touch panel or the like.And the panel of the touch structure that is adopted on automobile audio also is confined to mostly such as resistance class touch-screen, and this class touch-screen need touch and push, and serviceable life and performance still are difficult to ensure.

The utility model content

Technical problem to be solved in the utility model provides a kind of easy to operate, service-strong automobile audio.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of automobile audio comprises the sound equipment body, and the sound equipment body is provided with the touch control flow, and described touch control flow includes the touch circuit board of band touch sensible chip, touches circuit board and is connected with the sound equipment main control chip by interface.The connecting band transparent feel is answered the LCD display of touch pad on the touch circuit board, is with transparent feel to answer on the LCD display of touch pad the transparent insulation panel also is installed

The utility model has following remarkable result compared with prior art:

Automobile audio provided by the utility model has adopted to change by inductance capacitance and has realized the touch control flow controlled, makes operation control more arbitrarily easy.The utility model because do not have mechanical part, can not wear and tear and be according to finger near or touch the minor alteration that touches the electric capacity that control flow brought and realize controlling, do not need firmly to push, use lasting more reliable.Simultaneously, the pattern of the transparent insulation panel of its setting, button size, shape can design arbitrarily, and automobile audio outward appearance of the present utility model is more attractive in appearance, fashion and colour-fast, indeformable thereby make.

Description of drawings

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.

Fig. 1 is the utility model surface structure synoptic diagram; Fig. 2 is the longitudinal section synoptic diagram of Fig. 1;

Fig. 3 is a theory diagram of the present utility model.

Embodiment

Referring to Fig. 1,2 one kinds of automobile audios, the sound equipment body is provided with and touches control flow 1, and described touch control flow includes and touches circuit board 10, LCD display board 11 and transparent insulation panel 12, touches circuit board 10 and is connected with the sound equipment main control chip by interface.Touch connection LCD display board on the circuit board, and also be provided with transparent insulating panel on the LCD display board.Transparent insulating panel can be glass plate, plastic plate or ceramic wafer.But touch circuit board and be provided with the touch sensible chip that inductance capacitance changes, adopt the ADI9807 cake core as the touch sensible chip in the present embodiment, its universal strong is convenient to and the communication of sound equipment main control chip.Touch on the circuit board and be connected with LCD display, LCD display is to be provided with the LCD display that the band transparent feel is answered touch pad.

The touch control flow of this automobile audio is provided with viewing area 13, and periphery is provided with Petting Area 14.The design of can following one's inclinations of the pattern of viewing area, key zone, the size of button, shape can freely be selected, and the character on the touch-screen, trade mark perspective window etc. also can be arranged in pairs or groups arbitrarily simultaneously, good looking appearance, fashion, and also colour-fast.

Automobile audio with touch control flow provided by the utility model, the person's that can respond to the detecting operation finger moves the electric charge that brings and moves on touch-screen, the touch sensible chip is determined that finger is approaching or is touched sensitive surface by the minor alteration of monitoring electric capacity, the touch sensible chip circuit sends corresponding signal to sound equipment main control chip circuit according to the diverse location of finger touch, sound equipment main control chip circuit is controlled sound equipment after treatment to signal and is done corresponding actions, send signal simultaneously and give the LCD display driver circuit, finally on LCD display, show.

Provided by the utility model have an automobile audio that touches control flow, and reliability improves greatly, but and touch the design random variation of control flow, be fit to the demand of Hyundai Motor different-style.
