Embodiment
The embodiment of the present invention provides a kind of information processing method and electronic equipment, to reduce the technical matters of the voice signal distortion that the microphone of electronic equipment in prior art enrolled.
Technical scheme in the embodiment of the present application is for solving above-mentioned technical matters, and general thought is as follows:
When receiving the first steering order, first judge that whether voice output is in voice output state, and at voice output during in voice output state, control M voice collection device in N voice collection device of electronic equipment in acquisition state, and this N voice collection device comprises the first voice collection device that does not belong to M voice collection device, the first distance of the first voice collection device and voice output is less than arbitrary voice collection device in M voice collection device and the distance of voice output, also only command range voice output M voice collection device far away in opening, thereby the interference of the voice signal that the output sound that can reduce voice output gathers voice collection device, so reached the technique effect of the distortion level that reduces the voice signal that voice collection device gathers, and then final synthetic recording also can reduce the overlapping problem of background sound as far as possible.
In order better to understand technique scheme, below by accompanying drawing and specific embodiment, technical solution of the present invention is described in detail, be to be understood that the specific features in the embodiment of the present invention and embodiment is the detailed explanation to technical solution of the present invention, rather than the restriction to technical solution of the present invention, in the situation that not conflicting, the technical characterictic in the embodiment of the present invention and embodiment can combine mutually.
First aspect, the embodiment of the present invention provides a kind of information processing method, be applied in electronic equipment, electronic equipment comprises voice output and N voice collection device, N is more than or equal to 2 positive integer, electronic equipment is for example: mobile phone, panel computer, voice output is for example: sound equipment, voice collection device is for example: microphone etc.
Please refer to Fig. 2, this information processing method comprises the following steps:
Step S201: when electronic equipment receives the first steering order, judge that whether voice output is in voice output state, the first steering order is specially at least one voice collection device of controlling in N voice collection device steering order in acquisition state;
Step S202a: at voice output during in voice output state, from N voice collection device, determine M voice collection device, wherein, N voice collection device comprises the first voice collection device that does not belong to M voice collection device, and the first distance of the first voice collection device and voice output is less than arbitrary voice collection device in M voice collection device and the distance of voice output;
Step S203: control M voice collection device in sound collection state.
As further preferred embodiment, the method also comprises:
Step S202b: during not in voice output state, control N voice collection device in sound collection state at voice output.
In specific implementation process, in step S201, whether can detect in several ways voice output in voice output state, two kinds that enumerate below are wherein introduced, and certainly, in specific implementation process, are not limited to following two kinds of situations.
The first, judges that voice output, whether in voice output state, is specially:
Judge that whether voice output is in opening.For example, can detected electrons equipment whether in mute state, if electronic equipment in mute state, illustrates that voice output is not in opening; Again for example: can detect and control button that voice output carries out audio frequency output whether in opening, if button in opening, illustrates that voice output is in opening etc.
The second, judges that voice output, whether in voice output state, is specially:
Judge that whether voice output is in opening, and whether electronic equipment has moved audio frequency play-back application.
Specifically, namely should determine that voice output is in opening, and while existing music application program in running order, just determine that voice output is in voice output state, because voice output only can guarantee that in opening electronic equipment can output audio information, but do not represent that audio output device has outputting audio data, so increase the detection of audio frequency play-back application for whether detecting voice output in voice output state, there is more accurate technique effect.
As further preferred embodiment, determine M voice collection device from N voice collection device before, method also comprises:
Each voice collection device in N voice collection device of prestoring and the distance value of voice output, to obtain N distance value;
And then in step S202a, at voice output, during in voice output state, from N voice collection device, determine M voice collection device, be specially:
By N distance value, determine M voice collection device.
In specific implementation process, at electronic equipment initial phase, can detect respectively the distance of each voice collection device and voice output, and be pre-stored in electronic equipment, for example set up form as shown in table 1:
Table 1
And then, operational phase at electronic equipment can be determined M voice collection device by the relation of the determined correspondence of table 1, wherein can determine in several ways M voice collection device, two kinds that enumerate below are wherein introduced, certainly, in specific implementation process, be not limited to following two kinds of situations.
The first, the first voice collection device is removed from N voice collection device, take the corresponding relation shown in table 1 as example, that voice collection device 001 is removed from 4 voice collection device, then from remaining voice collection device, select at random M voice collection device, take M as 2 being example, so can select 002,004, also can select 002,003 etc.; Take M as 1 being example, can select so an arbitrary voice collection device in 002,003,004 as M voice collection device.
The second, the distance of N voice collection device and voice output is sorted, and then select apart from voice output distance M voice output farthest, in this case, as further preferred embodiment, the N that N voice collection device comprises except M sound collection subtracts M voice collection device, and N subtracts the distance that the distance of arbitrary voice collection device and voice output in M voice collection device is less than arbitrary voice collection device and voice output in M voice collection device.
Or take table 1 as example, can carry out sequence as shown in table 2 so:
Table 2
So, if M equals 1, the M a determining voice collection device is voice collection device 003, and it is 001,002,004 that M subtracts N voice collection device; If M equals 2, the M determining a so audio unit is voice collection device 003,002, it is 001,004 etc. that M subtracts N voice collection device, in this case, because M voice collection device is all the voice collection device away from voice output, so tool is further reduced the technique effect of voice output to the interference of voice collection device, and then further reduce the distortion level of the voice signal that voice collection device enrolls.
In step S202b, because voice output is not in voice output state, so the voice signal that voice output can not gather voice collection device causes interference, so in this case, in order to guarantee that electronic equipment can collect the voice signal of best results, need to control N voice collection device all in voice collection device.
Second aspect, based on same inventive concept, the embodiment of the present invention provides a kind of electronic equipment, please refer to Fig. 3, specifically comprises:
