Embodiment 2
In order to reduce the latency issue that left and right headphones sound is propagated, the present embodiment based on do 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 for exporting the left side of 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
Jing digital to analog converters, analog-digital converter are connected with the speaker 2 of left earphone successively to go out circuit, right audio channel output circuit Jing moulds
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 practical situation
Select.
It should be noted that the left audio output current, right audio channel output circuit, digital to analog converter and mould
Number converter can be integrated on the bluetooth module, also independently into a chip can be not limited to this.
Common wireless headset is all after an earphone receives the audio signal of the intelligent terminal such as mobile phone, with left ear
As a example 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
The speaker 2 exported to left ear earphone is connect, and right channel audio signal is exported to a radio transmitting and receiving chip and is AD converted, so
Afterwards the digital signal after conversion is wirelessly reflected away, the wireless signal can be Bluetooth signal, wifi signals, go back
Can be RF signals, but be not limited to this；Auris dextra earphone is normally made up of a wireless transceiver and speaker 2, receipts that this is wireless
Device is sent out by the wireless signal for receiving, such as RF signals, carries out process and isolate digital audio and video signals, then changed through DA again,
Final output to right ear speakers 2, so as to realize the left-right stereo of wireless headset.But, just because of the audio frequency of a sound channel
Signal is directly output to speaker 2, and the audio signal of another sound channel have passed through wireless signal transtation mission circuit transmission delay+AD and turn
Change time delay+wireless signal receiving circuit transmission delay+DA transfer delays so that the sound of a sound channel reach speaker 2 when
Between be smaller than the sound of another sound channel and reach the delay time of speaker 2, and this time=wireless signal transtation mission circuit is passed
Defeated time delay+AD conversion time delay+wireless signal receiving circuit transmission delay+DA transfer delays, in existing wireless headset, during the time 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 frequency letter
Number when, the bluetooth module of left earphone isolates left channel audio signal and right channel audio signal, and left channel audio signal Jing is left
Channel audio output circuit is exported to digital to 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 transmitting-receiving
Time is extremely short, generally less than 1ms, as the audition 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 time delay phenomenon of left and right headphones sound
On true wireless headset, also improve acoustical quality.
Embodiment described above only expresses embodiment of the present utility model, and its description is more concrete and detailed, but and
Therefore the restriction to this utility model the scope of the claims can not be interpreted as, as long as the institute in the form of equivalent or equivalent transformation
The technical scheme of acquisition, all should fall within protection domain of the present utility model.
