Example illustrates.
With reference to figure 6, when TV signal sources and intelligent mobile phone terminal are connected to apparatus for receiving audio simultaneously, TV signal sources are to sound
Frequency receiver sends wireline audio signal, and intelligent mobile phone terminal suspends or do not play audio, that is, has wireline audio signal defeated
It is fashionable, because intelligent mobile phone terminal suspends or does not play audio, control module in apparatus for receiving audio (in the present embodiment with
Exemplified by MCU) the GPIO signals that receive are low level, apparatus for receiving audio differentiates the input signal effectively (bluetooth of circuit input
Pause/closing is invalid), it is shown as high level.When bluetooth inputs, t1 times and intelligent mobile phone terminal Bluetooth pairing, t2 times are
Bluetooth pairing success, the t3 times are due to suspending or not playing duration of music low level.Circuit input accesses sound in the t4 times
Pattern, because GPIO is low level, the source of sound that LED light device plays inputs for circuit, and the audio signal of TV signal sources.By
Received in LED light device WIFI module among apparatus for receiving audio WIFI module and t5200mS time delays be present, t6 is audio
Reception device WIFI module is connected with LED light device WIFI module, and t7 high level inputs source of sound to play circuit.Due to circuit
Input signal is that analog signal can not directly be the identification of apparatus for receiving audio WIFI module, need to be I2S by codec conversion
Data signal is sent to the WIFI module of apparatus for receiving audio, then the I2S signals that the WIFI module receives are sent to LED and shone
The WIFI module of bright device.LED light device control module passes through the WIFI module in I2C and LED light device, amplifier mould
Block is communicated, and sending the signal to loudspeaker using amplifier module plays, and completes communication.
With reference to figure 7, when having wireless audio signal input simultaneously, bluetooth module and smart mobile phone are whole in apparatus for receiving audio
After end Bluetooth signal is shaken hands successfully, and intelligent mobile phone terminal selection broadcasting source of sound, MCU GPIO signals in apparatus for receiving audio
For high level.Bluetooth input signal effectively (circuit input broadcasting/pause is invalid) is differentiated simultaneously, and bluetooth module passes through UART protocol
Communicated with the MCU of apparatus for receiving audio, MCU is carried out using I2C buses and the WIFI module of apparatus for receiving audio, coding/decoding module
Communication.Timing diagram now as shown in Figure 7, wherein, t1 times and intelligent mobile phone terminal Bluetooth pairing, the t2 times match somebody with somebody for bluetooth
To success, the t3 times play bluetooth source of sound permanent High level.If circuit input accesses acoustic pattern in the t4 times, because bluetooth is defeated
Enter pattern to play, so the GPIO t8 times switch to high level by low level, the source of sound that LED light device plays is bluetooth sound
Source.T5200mS time delays, t6 be present because LED light device WIFI module is received among apparatus for receiving audio WIFI module
It is connected for receiving module WIFI module with LED light device WIFI module, t7 high level is broadcasting bluetooth source of sound.Coordinate reference chart
8, if TV signal sources do not access wireline audio signal, i.e., when only wireless audio signal inputs, the t1 times are whole with smart mobile phone
Bluetooth pairing is held, the t2 times are Bluetooth pairing success, and the t3 times play bluetooth source of sound permanent High level.Circuit input is due to pause
Or close and be configured to low level, now bluetooth input pattern is plays, so the GPIO t8 times switch to high electricity by low level
Flat, the source of sound that LED light device plays is bluetooth source of sound.Because LED light device WIFI module receives apparatus for receiving audio
T5200mS time delays among WIFI module be present, t6 is apparatus for receiving audio WIFI module and LED light device WIFI module
Connection, t7 high level are broadcasting bluetooth source of sound.Because Bluetooth signal is that analog signal can not directly be apparatus for receiving audio WIFI
Module identifies, need to be that I2S data signals are sent to the WIFI module of apparatus for receiving audio by coding/decoding module encoding and decoding conversion,
The I2S signals received are sent to LED light device WIFI module again.LED light device control module passes through I2C and LED
Lighting device WIFI module, amplifier module are communicated, and carrying out digital power amplifier using amplifier module sends the signal to loudspeaker
Broadcasting, so as to realize LED light device wireless acoustics function.
Radio play system provided in an embodiment of the present invention, the audio signal sent by receiving apparatus for receiving audio, and
Send the audio signal to LED light device control module and amplifier module, put the control of LED light device control module
Big device module is amplified to the audio signal, and the audio signal after amplification is output into audio playing module, so that audio
Playing module plays the audio signal after amplification.Because radio play system can integrate illumination and audio playing function,
Coordinate with apparatus for receiving audio, audio signal is received by way of radio communication and is played out, has saved home room, it is rich
The rich function of LED light device, it is possible thereby to improve the experience of user.
It is worth noting that, the radio play system of the present invention, can also utilize the mobile terminal such as smart mobile phone (IOS,
Android) application program (Application;Referred to as:APP), the work(such as the light modulation of control LED light device, regulation volume are realized
Energy.
