For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
Description of drawings
Fig. 1 is the audio circuit module of the utility model one embodiment and the circuit block diagram that mainboard electrically connects
Fig. 2 is the synoptic diagram of audio circuit module of the present utility model
Embodiment
Please refer to Fig. 1, it illustrates the audio circuit module of the utility model one embodiment and the circuit block diagram that mainboard electrically connects.This audio circuit module 100 comprises a signal control circuit 110, first bus controller 120, a data processing unit 130, a storage element 140 and second bus controller 150.Wherein, storage element (as flash memory) 140 can be used to store the music archive form, for example be MP3 music or other high tone quality music, and data processing unit 130 can read MP3 music and playing program thereof in the storage element 140, particularly under the situation that computing machine is not started shooting, the power supply that is provided by mainboard 160 comes supply data processing unit 130 required operating voltage and electric power, to play the MP3 music.In addition, after computing machine enters operating system, playing program in more can using system reads the MP3 music in the storage element 140, the detailed description of relevant signal control circuit 110, first bus controller 120, second bus controller 150 please refer to the synoptic diagram of the audio circuit module 100 of Fig. 2.
As shown in Figure 2, the signal control circuit 110 of audio circuit module 100 has a bus interface (not illustrating), it is connected to the bus controller 170 of mainboard 160 with four line USB cables 112, and the I/O pin position of signal control circuit 110 is connected to first bus controller 120 and second bus controller 150 respectively with four exclusive line USB cables 114,116 again.Wherein, first bus controller 120 can be connected to a coding/decoding circuit 132 of data processing unit 130, and the MP3 music that is stored in the storage element 140 can transfer to earphone or the lead-out terminal of loudspeaker 134 by the source of sound output of coding/decoding circuit 132.In addition, display unit 136 is coupled to the video output of data processing unit 130, in order to song or other video data that displays the play.In addition, module card 152 for example has the storage card slot of All-in-One, can connect compact flash (Compact Flash, CF) storage card, security disk (Security Disk, SD) storage card of various kind such as storage card and memory bar (Memory Stick) storage card.Moreover dish or other portable Storage Media also can be connected to signal control circuit 110 by bus connection port 154 with oneself, have the function of plug and play.
It should be noted that when computing machine is not started shooting audio circuit module 100 is powered by the power circuit 180 of mainboard 160, and comes supply data processing unit 130 and required operating voltage and the electric power of associated component with voltage conversion circuit 182.Therefore, when the user pushed the broadcast of one on register face button 138 under the situation of not starting shooting, data processing unit 130 these play instructions of response were deciphered to carry out sound signal, and play the MP3 music.Certainly, the also configurable operating key (not illustrating) that stops functions such as playing back music, selected songs on the computing machine front console.In addition, after computing machine enters operating system, the signal wire and the bus controller 120,150 thereof that see through USB cable 112,114,116 come transport address instruction or steering order, so that intrasystem playing program can read the MP3 music in the storage element 140, or the instruction of appointment being read or write the address is sent in storage card or the carry-on dish, to carry out data read or to write.
By above explanation as can be known, audio circuit module of the present utility model can be assembled on the computing machine front console, and provide independently power supply by computing machine, therefore under the situation that operating system is not started shooting, the user can play-over the music of MP3 File Format or other high tone quality form.Because the consumed power of audio circuit module much smaller than the consumed power of starting operating system, so can save a large amount of power consumptions, need not wait as long for starting operating system simultaneously, can play the MP3 music, and is more convenient in the use.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; anyly have the knack of this skill person; in not breaking away from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection domain of the present utility model is as the criterion when looking accompanying the claim person of defining.
