Embodiment
Can realize the FM function for solving the peripheral earphone that needs of mentioning in prior art as the FM antenna, and the FM play mode is single, can't support wireless network to play, can not support multi-user's problem simultaneously, the embodiment of the present invention provides a kind of FM player method, and specifically handling process is as shown in Figure 1:
Generate secondary signal after step 103, baseband chip modulation first signal, and export peripheral earphone to, by peripheral earphone, secondary signal is carried out demodulation and play, flow process finishes;
Generate the 4th signal after step 105, baseband chip modulation the 3rd signal;
In the specific implementation, the FM player method that the embodiment of the present invention provides can be applied on any equipment that the FM function can be provided, for example, can be applied on the similar devices such as mobile phone, computer, broadcast receiver, certainly, for guaranteeing that the user can receive new message and consulting whenever and wherever possible, also the FM player method can be applied on any mobile terminal, as long as this mobile terminal can provide the FM function.
While being applied on mobile terminal by FM frequency modulation player method, baseband chip, FM receiving chip, bluetooth module and Bluetooth antenna all are integrated in mobile terminal inside.
Flow process as shown in Figure 1, step 102 is when implementing, the FM receiving chip is through peripheral earphone antenna reception FM broadcast singal and modulated, generate first signal, concrete modulation system is as follows: the FM receiving chip is through peripheral earphone antenna reception FM broadcast singal, process through demodulation, filtering, amplification, mixing, ADC (Analog-to-Digital Converter, analog-digital conversion) conversion and DSP audio frequency, and output to baseband chip by DAC.Step 104 is when implementing, and the FM receiving chip receives the FM broadcast singal and modulated through built-in aerial, generates the 3rd signal, and concrete modulation system and the modulation system in step 102 are similar.
Shown in Fig. 1, flow process shows, except through built-in aerial receives the FM broadcast singal, can also receive the FM broadcast singal through external earphone antenna, in the specific implementation, there is external earphone antenna if current, utilize peripheral earphone antenna to receive the FM broadcast singal, do not have external earphone antenna if current, can utilize built-in aerial to receive the FM broadcast singal.
Flow process, can learn as shown in Figure 1, and the equipment of the FM frequency modulation player method that the application embodiment of the present invention provides at least exists bluetooth mode, outer mode playback and three kinds of implementations of peripheral earphone pattern, certainly, also may there be other patterns, can propagate FM broadcast and get final product, for example, infrared mode.In the specific implementation, can select different patterns according to actual conditions, for example, move, while driving, can select bluetooth mode, avoid impeding of earphone antenna, can, away from radiation, reduce the impact of electromagnetic wave on the people simultaneously.According to foregoing, can find out, the method that the embodiment of the present invention provides has guaranteed the variation that FM plays answer mode, configuration or user while selecting to change, when implementing, in the integrated switching controls module of terminal inner, use hardware mode to realize that selectivity connects peripheral earphone antenna or built-in aerial.Can utilize the switching controls module to be switched to fast applicable pattern, make the control between pattern more convenient.
Now with a specific embodiment, describe, in this example, have bluetooth mode, outer mode playback and three kinds of implementations of peripheral earphone pattern simultaneously, the embodiment of three kinds of patterns is as follows:
Pass through high-speed analog switch, input to three kinds of mode signals produces the output response, thereby the output stream of the audio analog signals of baseband chip output to, after the access of peripheral earphone antenna, baseband chip by control switch to the conducting of audio earphone loop, terminal is using the peripheral earphone antenna as the FM antenna simultaneously, broadcast singal is received into, by exporting from left and right acoustic channels linear analogue delivery outlet LOUT and ROUT after filtering, amplification, mixing, the processing of DSP audio frequency and digital-to-analogue conversion, output audio signal is transferred on headset after the baseband chip conversion again;
After the bluetooth earphone access, after the overmatching authentication, baseband chip by control switch to the loop conducting of audio frequency bluetooth, terminal is using built-in aerial as the FM antenna simultaneously, broadcast singal is received into, and by exporting from digital audio delivery outlet DOUT after filtering, amplification, mixing, the processing of DSP audio frequency and digital-to-analogue conversion, output audio signal is transferred on bluetooth module after the baseband chip conversion, through Bluetooth antenna, launch, bluetooth earphone receives again;
While putting outside FM is direct, baseband chip by control switch to audio player speaker loop conducting, terminal is using built-in aerial as the FM antenna simultaneously, broadcast singal is received into, by audio frequency process and digital-to-analogue conversion after from left and right acoustic channels linear analogue delivery outlet LOUT and ROUT output, output audio signal output after the baseband chip conversion, output broadcast singal after converting by electroacoustic.
Because playing, FM of the prior art can continue to play always, may consume large volume and electricity in short time, cost is higher, and the impression that can affect the user is experienced, for addressing this problem, the embodiment of the present invention also proposes, according to user's needs, a time threshold is set, when implementing, when the switching controls module detects in terminal that the not running status of any one or more elements maintains over setting-up time, baseband chip notice bluetooth module is out of service, notify each element to enter the low current sleep pattern, maintain the minimum current loss, adopt this measure can effectively reduce the power consumption of answering, prolongs standby time.
