Compared with prior art, it has the advantages that the present invention：A kind of home intelligent sound system of the present invention, i.e. achievable installation music APP of carrying Android system, magnanimity music online request, download when coming into operation, without the need for carrying any plug-in device, realization is freely played；Connection wireless network or cable network magnanimity music are freely played at random online, unrestricted in copyright, freely；HD Audio is exported, undistorted interim card；The audio frequency electric energy of loudspeaker passes through electromagnetism, piezoelectricity or electrostatic effect so as to which cone or diaphragm vibration simultaneously produce resonance with the air of surrounding（Sympathetic response）And sound is sent, pronunciation tonequality is high, and configures high-definition display screen, highly sensitive touch-screen and the supporting setting of sound equipment, takes leave of traditional type playback terminal and sound equipment clastotype.There is strict order between each instruction in the processing system running of the present invention, it is ensured that the correct operation of system work, not chaotic execution；According to the function to instructing, corresponding operating control signal is produced, be then issued to corresponding part and go execute instruction, corresponding action is carried out according to the requirement of instruction so as to control these parts；In the middle of the implementation procedure of instruction, strict timing is carried out to the enforcement time of various operations, it is ensured that system works without any confusion；Control all of operation, all of information data of processing system；Make to realize data communication, resource-sharing between all parts；When processing the data of all parts, using independent distributed treatment, operation mutually noiseless, the orderly execution between all parts is made, enhance the reliability of system.
Description of the drawings
Fig. 1 is the system block diagram of the present invention.
Specific embodiment
Refering to a kind of home intelligent sound system shown in Fig. 1, including ARM central processing units, I2S is switched, digital to analog converter, audio switch, audio-frequency power amplifier, loudspeaker and liquid crystal display, the ARM central processing units mainly include arithmetic unit, cache, data storage, control and status bus, the loudspeaker passes through electromagnetism, piezoelectricity or electrostatic effect make cone or diaphragm vibration and empathize with the air of surrounding, the I2S switches, digital to analog converter, audio switch, audio-frequency power amplifier, loudspeaker and liquid crystal display with ARM central processing units Electricity Federation.
The liquid crystal display adopts high-definition liquid crystal screen, and is installed as touch-screen, and the touch-screen is made up of the detection part and touch screen controller before display.
The touch-screen is using the capacitive touch screen by transparent metal level painting on a glass.The touch-screen surrounding is provided with elongated electrodes.
