The audio file that stores in the audio frequency holder of the present invention as advertisement as example, the following describes the concrete grammar of bluetooth earphone broadcast advertisement of the present invention.
There are two kinds of situations can broadcast advertisement during bluetooth earphone specific works of the present invention, see also shown in Figure 2, a kind of situation is when bluetooth earphone state detection unit 14 detects bluetooth earphone and is being in the pairing state, when for example being connected with mobile phone or panel computer, processor unit 15 reads in the audio memory 16 advertising message by audio-frequency module 17 and sound-producing device 19 broadcast advertisements.Detailed process comprises:
Step 21: the state of bluetooth earphone state detection unit Test earphone, whether Test earphone is in the pairing state.
Step 22: when the bluetooth earphone state detection unit detected earphone and is in the pairing state, the notification processor unit read advertising message in the audio memory by processor unit.
Step 23: the advertising message that processor unit control will be read from audio memory is carried out advertisement by audio-frequency module control and is play.
Step 24: the bluetooth earphone state detection unit detects the state of bluetooth earphone, whether successful matching is if successful matching then stops to read the advertising message in the audio memory, stop broadcast advertisement, perhaps also can keep bluetooth earphone to be in the state of broadcast advertisement always.
Step 25: be in connection status if the bluetooth earphone state detection unit detects bluetooth, then audio-frequency module switches to the audio signal of proper communication.
Another kind of situation is, when carrying out call by bluetooth earphone, when bluetooth earphone state detection unit 14 detected the other side and is in the waiting answering state, processor unit 15 read the advertising message in the audio memory 16, and with traditional the tinkle of bells that this alternative earphone end is sent, carry out advertisement and play.See also shown in Figure 3ly, detailed process comprises:
Step 31: the bluetooth earphone state detection unit detects the state of bluetooth earphone, detects bluetooth earphone and whether is in exhalation waiting answering state.
Step 32: when the bluetooth earphone state detection unit detected bluetooth earphone and is in the state of exhalation waiting answering, the notification processor unit read advertising message in the audio memory by processor unit.
Step 33: the advertising message that processor unit control will be read from audio memory is carried out advertisement by audio-frequency module control and is play.
Step 34: the bluetooth earphone state detection unit detects the other side and is in the state of answering, and then the notification processor unit stops to read advertisement from audio memory.
Step 35: processor unit switches to audio-frequency module the audio signal of proper communication.
See also shown in Figure 4, when bluetooth earphone is in the communication idle condition when (or being called resting state), bluetooth earphone of the present invention can arrange automatic detection advertisement program function, for example advertisement has renewal, when perhaps in mobile phone or the panel computer new advertisement being arranged, advertisement program in mobile phone or the panel computer can be downloaded in the bluetooth earphone, the advertisement of downloading is write audio memory.Be similar to the automatic software update program in the present computer.Its concrete steps are:
Step 41: the bluetooth earphone state detection unit detects the state of bluetooth earphone, judges whether bluetooth earphone is in the communication idle condition.
Step 42: if bluetooth earphone is in the communication idle condition, then bluetooth earphone is communicated by letter with mobile phone or panel computer and is downloaded advertisement in mobile phone or the panel computer.
Step 43: processor unit writes the advertisement of downloading in the audio memory.
In the aforementioned embodiment, what store in the described audio memory is advertisement, and in actual applications, this audio memory is not limited to only stores advertisement, and what also can store in this memory is the audio files such as music, recording.
Bluetooth earphone of the present invention can be when Bluetooth pairing or the advertisement that stores in the audio plays memory during bluetooth exhalation waiting answering, and the manufacturer that produces like this bluetooth earphone can allow manufacturer's patronage of want advertisement, and reduces the cost of bluetooth earphone manufacturer.
Above-mentioned explanation has fully disclosed the specific embodiment of the present invention.It is pointed out that and be familiar with the scope that any change that the person skilled in art does the specific embodiment of the present invention does not all break away from claims of the present invention.Correspondingly, the scope of claim of the present invention also is not limited only to previous embodiment.
