Embodiment
Can realize the FM function for solving the external earphone of mentioning in the prior art of needs 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 invention provides a kind of FM player method, and specifically handling process is as shown in Figure 1:
In the specific implementation, the FM player method that the embodiment of the 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 portable terminal, as long as this portable terminal can provide the FM function.
When being applied in FM frequency modulation player method on the portable terminal, baseband chip, FM receiving chip, bluetooth module and Bluetooth antenna all are integrated in portable terminal inside.
Flow process as shown in Figure 1, step 102 is when implementing, the FM receiving chip receives the FM broadcast singal and modulates through external earphone antenna, generate first signal, concrete modulation system is as follows: the FM receiving chip receives the FM broadcast singal through external earphone antenna, change and the DSP Audio Processing through demodulation, filtering, amplification, mixing, ADC (Analog-to-Digital Converter, analog-digital conversion), and output to baseband chip by DAC.Step 104 is when implementing, and the FM receiving chip receives the FM broadcast singal and modulates through built-in aerial, generates the 3rd signal, and concrete modulation system and the modulation system in the step 102 are similar.
Flow process shown in Figure 1 shows, except that through built-in aerial receives the FM broadcast singal, can also receive the FM broadcast singal through external earphone antenna, in the specific implementation, if currently have an external earphone antenna, utilize peripheral earphone antenna to receive the FM broadcast singal,, then can utilize built-in aerial to receive the FM broadcast singal if currently do not have an external earphone antenna.
By flow process shown in Figure 1, can learn that the equipment of the FM frequency modulation player method that the application embodiment of the invention provides exists bluetooth mode, outer mode playback and three kinds of implementations of external headset mode at least, certainly, also may there be other patterns, can propagate FM broadcasting and get final product, for example, infrared mode.In the specific implementation, can select different patterns, for example, move, can select bluetooth mode when driving, avoid impeding of earphone antenna, can reduce the influence of electromagnetic wave away from radiation simultaneously the people according to actual conditions.According to foregoing as can be seen, the method that the embodiment of the invention provides has guaranteed the variation that FM plays answer mode, configuration or user when selecting to change, when implementing, in the integrated switching controls module of terminal inner, use hardware mode to realize that selectivity connects external earphone antenna or built-in aerial.Can utilize the switching controls module to switch to suitable pattern fast, make the control between the pattern more convenient.
Now describe with a specific embodiment, in this example, have bluetooth mode, outer mode playback and three kinds of implementations of external headset mode 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 external earphone antenna inserts, baseband chip by control switch to the conducting of audio earphone loop, simultaneously terminal with external earphone antenna as the FM antenna, broadcast singal is received into, by exporting from left and right acoustic channels linear analogue delivery outlet LOUT and ROUT after filtering, amplification, mixing, DSP Audio Processing and the digital-to-analogue conversion, output audio signal is transferred on the headset after changing through baseband chip again;
After bluetooth earphone inserts, after the overmatching authentication, baseband chip by control switch to the loop conducting of audio frequency bluetooth, simultaneously terminal with built-in aerial as the FM antenna, broadcast singal is received into, and by exporting from digital audio delivery outlet DOUT after filtering, amplification, mixing, DSP Audio Processing and the digital-to-analogue conversion, output audio signal is transferred on the bluetooth module after changing through baseband chip, launch through Bluetooth antenna, bluetooth earphone receives again;
When outside FM is direct, putting, baseband chip by control switch to audio player speaker loop conducting, simultaneously terminal with built-in aerial as the FM antenna, broadcast singal is received into, by exporting from left and right acoustic channels linear analogue delivery outlet LOUT and ROUT after Audio Processing and the digital-to-analogue conversion, output audio signal is through baseband chip conversion back output, by exporting broadcast singal after the electroacoustic conversion.
Because playing, FM of the prior art can continue to play always, may consume big volume and electricity in short time, cost is higher, and the impression that can influence the user is experienced, for addressing this problem, the embodiment of the invention also proposes, needs according to the user are provided with a time threshold, when implementing, when the not running status that detects in the terminal any one or a plurality of elements when the switching controls module was kept above setting-up time, baseband chip notice bluetooth module was out of service, notify each element to enter the low current sleep pattern, keep the minimum current loss, adopt this measure can effectively reduce the power consumption of answering, prolongs standby time.
When implementing, the bluetooth earphone of configuration can be one, also can be for a plurality of, decide as the case may be, when the bluetooth earphone of configuration when being a plurality of, the switching controls module can be carried out the audio frequency shunting to the 5th signal according to the number control bluetooth module of bluetooth earphone, and the signal after will shunting outputs in a plurality of bluetooth earphones, and then can create the audio environment of a wireless network, realize the purpose that many people share.
