Fig. 6 is the sequential chart that radio play system plays source of sound, and Fig. 7 is another sequential chart that radio play system plays source of sound, and Fig. 8 is the sequential chart again that radio play system plays source of sound.Below in conjunction with Fig. 6 to Fig. 8, the playing principles of the radio play system of the embodiment of the present invention is set forth.Wherein, wireline audio signal source is with TV signal source, wireless audio signal source is specifically described for intelligent mobile phone terminal, in addition, first wireless communication module of apparatus for receiving audio is for bluetooth module, second wireless communication module is for WIFI module, and accordingly, LED light device wireless communication module is described for WIFI module.
With reference to figure 6; when TV signal source and intelligent mobile phone terminal are connected to apparatus for receiving audio simultaneously; TV signal source sends wireline audio signal to apparatus for receiving audio; and intelligent mobile phone terminal time-out or not audio plays; when namely having wireline audio signal to input; because intelligent mobile phone terminal suspends or not audio plays; the GPIO signal that control module (for MCU in the present embodiment) in apparatus for receiving audio receives is low level; apparatus for receiving audio differentiates the input signal of circuit input effectively (bluetooth is suspended/close invalid), is shown as high level.During bluetooth input, t1 time and intelligent mobile phone terminal Bluetooth pairing, the t2 time is Bluetooth pairing success, and the t3 time is owing to suspending or not playing duration of music low level.Circuit input accesses acoustic pattern in the t4 time, because GPIO is low level, the source of sound that LED light device is play is circuit input, and the audio signal of TV signal source.There is t5200mS time of delay due in the middle of LED light device WIFI module audio reception receiving system WIFI module, t6 is that apparatus for receiving audio WIFI module is connected with LED light device WIFI module, and t7 high level is for playing circuit input source of sound.Because line input signal is that analog signal can not directly for the identification of apparatus for receiving audio WIFI module, need be the WIFI module that I2S digital signal is sent to apparatus for receiving audio by codec conversion, then the I2S signal this WIFI module received be sent to the WIFI module of LED light device.LED light device control module is communicated with the WIFI module in LED light device, amplifier module by I2C, utilizes amplifier module signal to be sent to loudspeaker and plays, complete communication.
With reference to figure 7, when having wireless audio signal to input simultaneously, in apparatus for receiving audio, bluetooth module and intelligent mobile phone terminal Bluetooth signal are shaken hands successfully, and intelligent mobile phone terminal is selected to play source of sound, and in apparatus for receiving audio, MCUGPIO signal is high level.Differentiate Bluetooth input signal effectively (it is invalid that circuit input is play/suspended) simultaneously, bluetooth module is communicated with the MCU of apparatus for receiving audio by UART agreement, and MCU utilizes the WIFI module of I2C bus and apparatus for receiving audio, coding/decoding module communicates.As shown in Figure 7, wherein, t1 time and intelligent mobile phone terminal Bluetooth pairing, the t2 time is Bluetooth pairing success to sequential chart now, and the t3 time plays bluetooth source of sound permanent High level.If circuit input accesses acoustic pattern in the t4 time, because bluetooth input pattern is for playing, so the GPIOt8 time transfers high level to by low level, the source of sound that LED light device is play is bluetooth source of sound.There is t5200mS time of delay due in the middle of LED light device WIFI module audio reception receiving system WIFI module, t6 is that receiver module WIFI module is connected with LED light device WIFI module, and t7 high level is for playing bluetooth source of sound.Coordinate with reference to figure 8, if TV signal source does not access wired audio signal, when namely only having wireless audio signal to input, t1 time and intelligent mobile phone terminal Bluetooth pairing, the t2 time is Bluetooth pairing success, and the t3 time plays bluetooth source of sound permanent High level.Circuit input is configured to low level owing to suspending or closing, and now bluetooth input pattern is for playing, so the GPIOt8 time transfers high level to by low level, the source of sound that LED light device is play is bluetooth source of sound.There is t5200mS time of delay due in the middle of LED light device WIFI module audio reception receiving system WIFI module, t6 is that apparatus for receiving audio WIFI module is connected with LED light device WIFI module, and t7 high level is for playing bluetooth source of sound.Because Bluetooth signal is that analog signal can not directly for the identification of apparatus for receiving audio WIFI module, need be the WIFI module that I2S digital signal is sent to apparatus for receiving audio by coding/decoding module encoding and decoding conversion, then the I2S signal received is sent to LED light device WIFI module.LED light device control module is communicated with LED light device WIFI module, amplifier module by I2C, utilizes amplifier module to carry out digital power amplifier and signal is sent to loudspeaker broadcasting, thus realize LED light device wireless acoustics function.
The radio play system that the embodiment of the present invention provides, by the audio signal that audio reception receiving system sends, and send this audio signal to LED light device control module and amplifier module, LED light device control module control amplifier module is amplified this audio signal, and the audio signal after amplifying is outputted to audio playing module, play the audio signal after amplifying to make audio playing module.Because radio play system can integrate illumination and audio playing function, coordinate with apparatus for receiving audio, play by the mode received audio signal of radio communication, saved home room, enrich the function of LED light device, the experience of user can have been improved thus.
It should be noted that radio play system of the present invention, the mobile terminals such as smart mobile phone (IOS, Android) application program (Application can also be utilized; Be called for short: APP), realize controlling LED light device light modulation, regulating the functions such as volume.
