Embodiment 3
In order to reduce the latency issue that left and right headphones sound is propagated, the present embodiment be based on doing on the basis of embodiment 1 or 2 into
One step is improved, and as shown in Figure 5 b, the bluetooth module of the left earphone is also respectively connected with the left side for exporting left channel audio signal
Channel audio output circuit and the right audio channel output circuit for exporting right channel audio signal, the left audio are defeated
Go out circuit to be connected with the loudspeaker 2 of left earphone through digital analog converter, analog-digital converter successively, right audio channel output circuit is through mould
Number converter is connected with wireless antenna 4.Above-mentioned improvement can also be directed to the bluetooth module of right earphone, can be according to actual conditions
Select.
It is worth noting that, the left audio output current, right audio channel output circuit, digital analog converter and mould
Number converter can be integrated on the bluetooth module, also can be not limited to this independently into a chip.
Common wireless headset is all after receiving the audio signal of the intelligent terminals such as mobile phone by an earphone, with left ear
Exemplified by earphone, as shown in Figure 5 a, L channel and right channel audio signal are isolated by bluetooth module, left channel audio signal is straight
Output is connect to the loudspeaker 2 of left ear earphone, and right channel audio signal is exported to a radio transmitting and receiving chip and is AD converted, so
The data signal after conversion is wirelessly reflected away afterwards, the wireless signal can be Bluetooth signal, wifi signals, go back
It can be RF signals, but be not limited to this；Auris dextra earphone is normally made up of a wireless transceiver and loudspeaker 2, receipts that this is wireless
The wireless signal that hair device will receive, such as RF signals, carries out processing and isolates digital audio and video signals, is then changed again by DA,
Final output is to right ear speakers 2, so as to realize the left-right stereo of wireless headset.But just because of the audio of a sound channel
Signal is directly output to loudspeaker 2, and the audio signal of another sound channel have passed through wireless signal transtation mission circuit transmission delay+AD and turn
Change delay+wireless signal receiving circuit transmission delay+DA transfer delays so that the sound of sound channel reach loudspeaker 2 when
Between be smaller than the sound of another sound channel and reach the delay time of loudspeaker 2, and this time=wireless signal transtation mission circuit passes
Defeated delay+AD conversion delay+wireless signal receiving circuit transmission delay+DA transfer delays, in existing wireless headset, during the delay
Between about 100ms to 0.7s.
And the present embodiment wireless headset has done a change in the transfer voice of left earphone, i.e.,：When earphone receives audio letter
Number when, the bluetooth module of left earphone isolates left channel audio signal and right channel audio signal, and left channel audio signal is through a left side
Channel audio output circuit is exported to digital analog converter, analog-digital converter, is then transmit to left earphone speaker 2；R channel sound
The transmission of frequency signal does not change.Then, the sound time difference of left and right acoustic channels only has the transmitting-receiving time of wireless signal, but this is received and dispatched
Time is extremely short, generally less than 1ms, because the sense of hearing of human ear has attonita, can only receive the signal between 0~20Khz.Cause
This, has used the wireless headset of the present embodiment, then fundamental sensation realizes real meaning less than the delay phenomenon of left and right headphones sound
On true wireless headset, also improve acoustical quality.
Embodiment described above only expresses embodiments of the present invention, and its description is more specific and detailed, but can not
Therefore the limitation to the scope of the claims of the present invention is interpreted as, as long as the skill obtained using the form of equivalent substitution or equivalent transformation
