Distance between described detection talker and mobile phone microphone comprises: in the talker gap of talking, detect the distance between talker and mobile phone microphone.
Described adjusting mobile phone microphone volume comprises: carry out in the talker gap of talking, regulate the mobile phone microphone volume.
The present invention also provides a kind of device of automatic adjusting mobile phone microphone volume, is used under the handfree speech of mobile phone pattern, it is characterized in that, comprising:
Range sensor is used to detect the distance between talker and mobile phone microphone;
Computing unit, be used to adjust the distance sensor to distance average;
The contrast call unit, be used for the range averaging value that described computing unit is drawn and preset the mobile phone microphone volume gain and talker and mobile phone microphone distance regions between the table of comparisons compare, and call the interval corresponding mobile phone microphone volume gain of this range averaging value respective distance in the described table of comparisons;
Regulon is used for regulating the mobile phone microphone volume according to contrasting the mobile phone microphone volume gain that call unit calls.
Wherein, described range sensor places in the mobile phone, and described computing unit, contrast call unit and regulon place in the mobile phone base band chip.
The method and the device thereof of automatic adjusting mobile phone microphone volume of the present invention, under the handfree speech of mobile phone pattern, by detecting the distance between talker and mobile phone microphone, and obtain a range averaging value, and with this range averaging value and preset the mobile phone microphone volume gain and talker and mobile phone microphone distance regions between the table of comparisons compare, call the interval corresponding mobile phone microphone volume gain of this range averaging value respective distance in the described table of comparisons, in order to regulate the method for mobile phone microphone volume, realized that the mobile phone microphone volume can regulate apart from the distance of mobile phone microphone automatically according to the talker, ensured that the listener can have good audibility.
Description of drawings
Fig. 1 is the method flow schematic diagram of the described automatic adjusting mobile phone microphone volume of the embodiment of the invention;
Fig. 2 is the apparatus structure schematic diagram of the described automatic adjusting mobile phone microphone volume of the embodiment of the invention.
Embodiment
Below, describe the present invention in conjunction with the accompanying drawings.
As Fig. 1, present embodiment provides a kind of method that is used in the automatic adjusting mobile phone microphone volume under the handfree speech of mobile phone pattern, and this method comprises:
After continuous detecting n time, obtain the distance of n talker and mobile phone microphone, this n distance averaged, promptly obtain range averaging value A.
Here, a time T detects the distance between talker and mobile phone microphone at interval, and when interlude T was 0, expression detected in real time, and when interlude T was not 0, the expression poll detected.Wherein, interlude is short more, and the range averaging value A that obtains is accurate more.General n * T is the whole sampling time section of range averaging value A, is set to usually about 1 second.
The table of comparisons is between the above-mentioned mobile phone microphone volume gain that presets in mobile phone and talker and mobile phone microphone distance regions:
| The mobile phone microphone volume gain | Between the distance regions between talker and the mobile phone microphone |
| G1 | D0-D1 |
| G2 | D1-D2 |
| ... | … |
| Gn | D(n-1)-D(n) |
Wherein, suppose under the hand-free call pattern that the gain of mobile phone microphone is G, difference for the path loss size that remedies the voice signal under the different speech ranges, obtain the actual mobile phone microphone volume gain under the different distance condition by experiment, and produce table, be stored in the mobile phone.Which contrast range averaging value A drops on apart from segment, calls this mobile phone microphone volume gain G value apart from the segment correspondence then, according to this G value, regulates the mobile phone microphone volume.
The volume that causes the listener to hear for the variation that prevents microphone volume gain in the mobile phone communication produces sudden change, and when detecting the distance between talker and mobile phone microphone and regulating the mobile phone microphone volume gain, carry out in the speech gap that generally is selected in the talker.
As shown in Figure 2, this has implemented also to provide a kind of device of regulating the mobile phone microphone volume under the handfree speech of mobile phone pattern automatically that is used in, and this device comprises:
Regulon 23 is used for regulating the mobile phone microphone volume according to contrasting the mobile phone microphone volume gain that call unit calls.
Wherein, range sensor 30 can place in the mobile phone.Computing unit 21, contrast call unit 22 and regulon 23 can place in the mobile phone base band chip 20.
After the regulon in the mobile phone base band chip 23 had been regulated the mobile phone microphone volume, its output signal sent to radio frequency unit 40, launched by antenna 50 again, received for the far-end listener.
As seen, the mobile phone with automatic adjusting mobile phone microphone volume comprises: range sensor 30, mobile phone base band chip 20, radio frequency unit 40 and antenna 50.
Same, the volume that causes the listener to hear for the variation that prevents microphone volume gain in the mobile phone communication produces sudden change, and when detecting the distance between talker and mobile phone microphone and regulating the mobile phone microphone volume gain, carry out in the speech gap that generally is selected in the talker.
In sum, this has implemented the method and the device thereof of described automatic adjusting mobile phone microphone volume, under the handfree speech of mobile phone pattern, by detecting the distance between talker and mobile phone microphone, and obtain a range averaging value, and with this range averaging value and preset the mobile phone microphone volume gain and talker and mobile phone microphone distance regions between the table of comparisons compare, call the interval corresponding mobile phone microphone volume gain of this range averaging value respective distance in the described table of comparisons, in order to regulate the method for mobile phone microphone volume, realized that the mobile phone microphone volume can regulate apart from the distance of mobile phone microphone automatically according to the talker, ensured that the listener can have good audibility.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
