Embodiment
Below in conjunction with drawings and the specific embodiments the present invention program is described in further detail.
The present invention program as shown in Figure 1, corresponding following steps:
Step 101, radio sound source become some frequency ranges with the wireless transmission band segmentation when needs transmitting audio data signal, and send the wireless search message of search wireless sound box according to different frequency range.
Specifically, when radio sound source needs the outputting audio data signal, send request, carry out frequency range by wireless launcher and cut apart and send wireless search message to the self radio emitter.Carrying out frequency range when cutting apart, if frequency band is 2.40GHz-2.48GHz, then this frequency band can be divided into 16 frequency ranges, the bandwidth of each frequency range is 0.005GHz.Wireless search message then can send successively according to frequency range, such as according to frequency range 1, frequency range 2 ..., frequency range 16 sends.
This radio sound source can be the computer sound card that connected wireless launcher, DVD player, CD player, VCD player etc.
Step 102, wireless sound box are being received this wireless search message and are being determined that this wireless sound box after the current free time, returns corresponding response message.
Suppose currently to exist wireless sound box A to be in to receive frequency range 6, so this audio amplifier A can receive wireless search message in frequency range 6 that then it sends the response message of wireless search message current free time with frequency range 6 after determining self.
Step 103, radio sound source with the pairing frequency range of the response message of receiving as current transmit frequency band.
Specifically, this step can be determined current transmit frequency band according to the pairing frequency range of receiving of response message by the wireless launcher in the radio sound source.Wireless launcher sends voiceband data signal output request responding message to radio sound source, and replys current state after determining current transmit frequency band, and this state can be for being ready for signal processing etc.
In addition, in this step, the pairing frequency range of response message that wireless launcher can directly be received first is as current transmit frequency band.Then in above-mentioned steps 101, wireless launcher is when sending wireless search message according to different frequency range, if received the response message that certain wireless sound box sends, then this wireless launcher can be determined current transmit frequency band, does not therefore just need to have sent wireless search message again.Such as, first response message of receiving of wireless launcher sends for wireless sound box A, and this wireless sound box A is in frequency range 6, then wireless launcher can be with this frequency range 6 as current transmit frequency band, and stop to send wireless search message according to other frequency ranges.The pairing detailed process of this processing procedure as shown in Figure 2.Obviously, if the current environment of living in of user has only a wireless sound box, then can determine the current wireless sound box that is used to play soon by processing procedure shown in Figure 1.
In this step, because wireless launcher is after receiving each response message, the frequency range that can determine this response message place has corresponding wireless sound box, therefore at first preserve the pairing frequency range of each response message, and the wireless search message of each frequency range all sent finish after, judge that the frequency range preserved is one or a plurality of, if one, then directly with this frequency range as current transmit frequency band; If a plurality of, then from these frequency ranges, select one as current transmit frequency band.Such as, wireless launcher has been received the response message that wireless sound box A sends with frequency range 6, and the response message that sends with frequency range 9 of wireless sound box B, then should select one as current transmit frequency band from wireless sound box A and the pairing frequency range of B.The pairing detailed process of this processing procedure as shown in Figure 3.If the current environment of living in of user has two groups or more audio amplifier, then can from these audio amplifiers, select one group and be used for current audio plays by processing procedure shown in Figure 3.
Specifically, if the frequency range of being preserved is a plurality of, then wireless launcher can be selected according to the signal power of the response message of being received, such as, select the strongest frequency range of signal as current transmit frequency band.Why select according to the signal power, be because the user normally used be near audio amplifier, and the signal power of wireless sound box is inversely proportional to distance often, therefore, selects to select the nearest audio amplifier from the user according to the signal power.
Certainly, have under the situation of a plurality of frequency ranges, can also further ask the user that selection is provided, such as, owing to also carried the specification information of wireless sound box in the response message, so wireless launcher can also be preserved the pairing wireless sound box information of this frequency range simultaneously when preserving frequency range, and these wireless sound box information are offered the user, determine current transmit frequency band according to user's selection then.Such as, if the user has selected wireless sound box B from wireless sound box A and wireless sound box B, then wireless launcher with the residing frequency range of wireless sound box B as current transmit frequency band.The pairing detailed process of this processing procedure as shown in Figure 4.
Select the scheme of wireless sound box for above-mentioned by the user, corresponding processing module can be set in the wireless launcher of radio sound source, then start this processing module if desired.Correspondingly, wireless launcher judges then whether this processing module starts, when this processing module starts and defines a plurality of frequency ranges and have corresponding wireless sound box, upload the specification information of these wireless sound boxes to the user, and determine current transmit frequency band according to user's selection; If this processing module is not activated, then when defining the wireless sound box of a plurality of frequency ranges existence correspondences, directly select the strongest frequency range of signal as current transmit frequency band.The pairing detailed process of this processing procedure then as shown in Figure 5.
Determine scheme for above-mentioned various frequency ranges, have under a plurality of situations in the frequency range of preserving, occur determined frequency range possibly the corresponding with it situation of a plurality of wireless sound boxes is arranged, at this moment, for guaranteeing only to carry out voice playing by selected wireless sound box, also should require wireless sound box simultaneously the specification information of self to be sent together by response message, this specification information can comprise device identifier, facility information etc., so that the wireless launcher in the radio sound source is provided with current other wireless sound boxes that are in same frequency range other frequency range.For the change frequency range, received the response message that wireless sound box C, D, E send such as radio sound source, and wireless sound box C is identical with the residing frequency range of D, all be in frequency range 10, and the wireless sound box of radio sound source current selected is C, therefore, need radio sound source to send the message of revising frequency range, and carry the specification information of the wireless sound box D that needs the modification frequency range in this message with current transmit frequency band 10.Like this, be in the wireless sound box C of frequency range 10 and D together and all can receive this frequency range and revise message, but because the entrained specification information of this message is the specification information of wireless sound box D, so wireless sound box D can revise the frequency range of self, such as, self frequency range is added one; And this specification information and wireless sound box C are irrelevant, so wireless sound box C does not deal with this frequency range modification message.
Also need to prove, for making the frequency range of amended frequency range and other wireless sound boxes all inequality, can also be by the definite frequency range that can be modified as of radio sound source, and in this frequency range modification message, further increasing band information, wireless sound box can be revised as the frequency range of self this frequency range revises the entrained frequency range of message.Certainly, a plurality of if the wireless sound box that needs to revise under same frequency range has, then radio sound source can be revised message for each audio amplifier send frequency range respectively, also can be that all audio amplifiers send a frequency range and revise message.
Can realize related between wireless sound box and the radio sound source by above-mentioned steps.
Radio sound source is after receiving the current response message that has been ready to signal processing of wireless launcher, voiceband data signal can be exported to the sound effect processing module in the wireless launcher, by the sound effect processing module signal is handled, the signal of M sound channel of output, send to wireless transmitter module then, by wireless transmitter module the signal of this M sound channel is modulated, and, by the wireless antenna module this radiofrequency signal is radiate with the electromagnetic wave form again through exporting the radiofrequency signal of certain power after frequency conversion and the amplification.
Correspondingly, wireless sound box is in the message of receiving the search wireless sound box and after replying response message, then receive voiceband data signal by the wireless antenna module in the radio receiver, the radiofrequency signal that receives is changed into level signal, and export to wireless receiving module, demodulate baseband signal by wireless receiving module, and baseband signal is carried out power amplification, thereby promote sound horn by audio frequency power amplifier module.The handling process of wireless sound box as shown in Figure 6.
The above only is the present invention program's preferred embodiment, not in order to limit protection scope of the present invention.
