First, when user is for utilizing hand-held device 11 control figure sound equipment 12, user can click prior to hand-held device 11 and open an application program (APP), this application program can in be built in hand-held device 11 or after being downloaded by user and be installed in hand-held device 11.

After this application of unlatching, by display one user interface 113 (User Interface on screen (the first VISIBLE LIGHT EMISSION element 111), UI), as shown in Figure 3, user's interface 113 comprises the first Play Control instruction 1131 to the 4th Play Control instruction 1134, in this example, the first Play Control instruction 1131 is " starting from front once time-out place to play ", second Play Control instruction 1132 is " shuffle ", 3rd Play Control instruction 1133 is " playing the first song list ", 4th Play Control instruction 1134 is " setting up song list ", but not as limit.Note that the use being only shown in figure and illustrating, and the form being not used to the user's interface 113 limited in this example and the Play Control instruction had thereof.

It should be noted that, each Play Control instruction has its each self-corresponding binary command code, and it presets and can be identified by digital sound 12 and perform.For example, the binary command code that first Play Control instruction 1131 is corresponding in this example is 11011110, the corresponding binary command code of second Play Control instruction 1132 is 01010010, the corresponding binary command code of 3rd Play Control instruction 1133 is 11011101, the corresponding binary command code of 4th Play Control instruction 1134 is then 00001111, but not as limit.

Then user can select one or more Play Control instruction in user's interface 113, if user have selected the first Play Control instruction 1131, namely after front once time-out place starts to play and confirms execution, binary command code A corresponding to the control information X produced when confirming selection first Play Control instruction 1131 is sent to the first scrambler 1121 by command receiver 114, simultaneously hand-held device 11 will show an information in user's interface 113 and turns to the first optical sensor 1211 of digital sound 12 to send control information X screen (the first VISIBLE LIGHT EMISSION element 111) to remind user.After digital sound 12 sends the response sound, represent that control information X has transmitted, hand-held device 11 can be removed by user.

It should be noted that, a digital sound 12 may have many hand-held devices together to use, in order to the controlling behavior meeting particular handheld device can be performed, namely personalized controlling behavior, digital sound 12 need learn control information X is by which hand-held device transmission, therefore in this example, control information X will comprise the hand-held device identification code of the first Play Control instruction 1131 and hand-held device 11, so command receiver 114 is except transmitting binary command code A1 to the first scrambler 1121 corresponding to the first Play Control instruction 1131, also need binary command code A2 to the first scrambler 1121 corresponding to hand-held device identification code transmitting hand-held device 11.

In this example, hand-held device identification code can be the title that user sets, such as code name " D ", but not as limit, hand-held device identification code can also be International Mobile Equipment Identity (the International Mobile Equipment Identity of hand-held device 11, IMEI) code or medium education (Media Access Control, MAC) address etc.As shown in Figure 4, in this example, the binary command code A2 corresponding to hand-held device identification code of hand-held device 11 is 01000100.

Next, first scrambler 1121 will carry out coding operation to binary command code A1 and A2 and obtain the first pulse signal B, first pulse signal B comprises multiple high potential signal with phase co-altitude and different in width, wherein the height representative voltage intensity of high potential signal, below will further illustrate.First, refer to Fig. 4, to be the high potential signal of 2 milliseconds (ms) and width by width in this example be, and the low-potential signal of 2 milliseconds is defined as 0, and to be the high potential signal of 4 milliseconds and width by width be, and the low-potential signal of 2 milliseconds is defined as 1, the wherein width representation signal duration of high potential signal.Therefore as shown in Figure 4, namely binary command code A2 corresponding to hand-held device identification code is converted into hand-held device identification signal B2 according to aforementioned definitions, and the binary command code A1 corresponding to the first Play Control instruction 1131 is then converted into Play Control command signal B1 according to aforementioned definitions.

Moreover, for the scope of clear definition binary command code A1 and A2, in this example, also add start signal B3 respectively at before Play Control command signal B1 and hand-held device identification signal B2, and add termination signal B4 respectively after Play Control command signal B1 and hand-held device identification signal B2.

In addition, for clearly separating binary command code A1 and A2, in this example, also between Play Control command signal B1 and hand-held device identification signal B2, a blank signal B5 is added.Finally, Play Control command signal B1, hand-held device identification signal B2, start signal B3, termination signal B4 and blank signal B5 form the first pulse signal B of this example jointly.

It should be noted that, to be the high potential signal of 8 milliseconds and width by width in this example be, and the low-potential signal of 2 milliseconds is defined as start signal B3, and to be the high potential signal of 6 milliseconds and width by width be, and the low-potential signal of 4 milliseconds is defined as termination signal B4, then to be the high potential signal of 2 milliseconds and width by width be, and the low-potential signal of 20 milliseconds is defined as blank signal B5.

And then, the first pulse signal B is transferred into the first photomodulator 1122, and the first photomodulator 1122 will control screen (the first VISIBLE LIGHT EMISSION element 111) with the first pulse signal B.Because high potential signal will make screen (the first VISIBLE LIGHT EMISSION element 111) luminous, it is luminous that low-potential signal will make screen (the first VISIBLE LIGHT EMISSION element 111) stop, and therefore the first pulse signal B constantly switches its light on and off state with special frequency by making screen (the first VISIBLE LIGHT EMISSION element 111) and sends the first visible light signal P.

Then, the first optical sensor 1211 is responded to the light on and off state change of screen (the first VISIBLE LIGHT EMISSION element 111) and will produce corresponding first electric signal while receiving the first visible light signal P.For example, when using photoresistance as the first optical sensor 1211, based on photoresistance when light source is gradually dark, resistance value can raise, and when light source is gradually bright, the characteristic that resistance value can decline with light-source brightness, namely the first optical sensor 1211 can produce the first corresponding electric signal.

Next, first electric signal will be transferred into the first preprocessor 1231, in this example, the first preprocessor 1231 is wave filter or amplifier, its median filter is for removing undesired composition in signal or strengthening the composition needed in signal, and amplifier is then for being amplified faint signal.No matter therefore the first preprocessor 1231 is wave filter or amplifier, its object is all to reduce interference to make the first electric signal closer to the first pulse signal B.

Then be transferred into the first optical demodulator 1232 via the first electric signal after the first preprocessor 1231 adjusts, the first electric signal to be reduced to the first pulse signal B do not decoded, in this example, the first optical demodulator 1232 is a level comparator.Last the first pulse signal B do not decoded is transferred into first information interpreter 1233, namely first pulse information B is reduced to the binary command code A2 corresponding to hand-held device identification code and the binary command code A1 corresponding to the first Play Control instruction 1131 according to the coding rule of aforementioned first scrambler 1121 by first information interpreter 1233, and obtains control information X by binary command code A1 and A2.

Namely digital sound 12 identifies hand-held device 11 and asks to start from front once time-out place to play according to control information X.Because digital sound 12 will record the use situation of each device, therefore digital sound 12 will find the broadcasting record of hand-held device 11 in its data database, and before hand-held device 11, once stop broadcasting place to start to play.

Moreover, if user have selected the second Play Control instruction 1132 and the 3rd Play Control instruction 1133 in user's interface 113, i.e. shuffle and broadcasting the first song list, then digital sound 12 is by after receiving binary command code A2, the binary command code corresponding to the second Play Control instruction 1132 and the binary command code corresponding to the 3rd Play Control instruction 1133 corresponding to hand-held device identification code, obtains the first song list corresponding to hand-held device 11 and the song in shuffle first song list in its data database.

If user only have selected the second Play Control instruction 1132 in user's interface 113, i.e. shuffle, then hand-held device 11 by the binary command code that only transmits corresponding to the second Play Control instruction 1132 to digital sound 12, make song in its data database of digital sound 12 shuffle, and do not need the hand-held device identification code transmitting hand-held device 11.

In addition, if user have selected the 4th Play Control instruction 1134 in user's interface 113, namely song list is set up, then user need prior to setting song list content in user's interface 113 of hand-held device 11, then digital sound 12 is by after receiving binary command code A2, the binary command code corresponding to the 4th Play Control instruction 1134 and the binary command code corresponding to song list corresponding to hand-held device identification code, sets up the song list corresponding to hand-held device 11 in its data database.

In brief, the first visible light signal P transmitting control information X that the music playing system 1 of this example is sent by the first VISIBLE LIGHT EMISSION element 111, and then control figure sound equipment 12 performs corresponding controlling behavior.Therefore, the music playing system 1 of this example can utilize the light on and off state communicating control information X controlling the existing screen of hand-held device 11 not need by communication communicating control information X to digital sound 12, and then solve the problem of aforementioned radio radio communication, and perform personalized controlling behavior by transmitting hand-held device identification code.
