Embodiment
The invention provides a kind of method and electronic equipment of adjusting loud speaker, in order to solve the technical problem that can not obtain the optimal response of loud speaker in prior art under non-standard environment.
Technical scheme in the embodiment of the present invention is for solving above-mentioned technical problem, and general thought is as follows:
Under first environment, in real time by the loud speaker outputting standard sound of electronic equipment, then the built-in microphone by electronic equipment is captured in the voice signal that first environment sound under described first environment and standard voice mix; Then by this first sound tone signal is analyzed, obtain the frequency response curve information of this loud speaker; If the frequency response curve information under this frequency response curve information and default environment does not match, illustrate that this loud speaker does not reach optimal response effect, so need to adjust the output parameter of loud speaker, so that it reaches optimal response effect; And if frequency response information under this frequency response curve information and default environment matches, illustrate that this loud speaker has reached optimal response effect.
In order better to understand technique scheme, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.
One embodiment of the invention provide a kind of method of adjusting loud speaker, and described method is applied in one and comprises in the electronic equipment of loud speaker, and this electronic equipment is such as being: the electronic equipments such as mobile phone, panel computer, notebook computer.
Please refer to Fig. 1, the method comprises the steps:
S101: when described electronic equipment is exported the standard voice corresponding with standard voice signal by described loud speaker, the first sound tone signal that acquisition collects by sound collection unit, wherein, described first sound tone signal is the first environment sound of first environment at described electronic equipment place and first sound tone signal corresponding to the first sound that described standard voice is mixed to form;
Wherein, in one embodiment, as shown in Figure 2, step S101 specifically comprises again:
S201: at least one the environmental parameter value that detects described electronic equipment place environment;
After obtaining at least one environmental parameter value based on step S201, just can perform step S202, that is: whether described at least one the environmental parameter value of judgement meets pre-conditioned;
After judging based on step S202, just can perform step S203, that is: in described at least one environmental parameter value, meet described when pre-conditioned, by the described loud speaker output standard voice corresponding with standard voice signal;
After based on step S203 outputting standard sound, just can perform step S204, that is: obtain the described first sound tone signal collecting by sound collection unit.
Specifically, be exactly before obtaining first sound tone signal, first gather at least one the environmental parameter value that obtains loud speaker place environment.In one embodiment, described environmental parameter value can be: environmental noise value, sound refractive index and sound reflection rate.Then, judge whether these environmental parameter values meet pre-conditioned, specifically: namely judge that whether at least one parameter information is similar with the parameter information under default environment, such as: whether environmental noise value is less than the first predetermined threshold value, such as 10dB, 20dB etc.; And judge whether sound refractive index is less than the second predetermined threshold value, and whether sound reflection rate is less than the 3rd predetermined threshold value etc.If these three conditions all meet, so, illustrate that this electronic equipment place environment is standard environment, and generally, loud speaker is not being made while arranging, and its output parameter can reach best response effect under standard environment, so do not need the output parameter of loud speaker to adjust; And if in these three conditions, at least exist one undesirable, illustrate that electronic equipment place environment is non-standard environment, so, need to adjust loud speaker, thereby just need to gather this first sound tone signal by sound collection unit.
As seen from the above description, due in the embodiment of the present application, when environment at least one environmental parameter value do not meet when pre-conditioned, just whether loud speaker being reached to optimal response effect detects, and generally, when environmental noise is smaller, loud speaker generally can reach best response effect, so guaranteeing that loud speaker has under the prerequisite of optimal response effect, reaching the technique effect of saving energy consumption.
And in another embodiment, step S101 specifically comprises again:
One timer is set in described electronic equipment, every Preset Time interval, produces a triggering command;
Based on described triggering command, by the described loud speaker output standard voice corresponding with standard voice signal;
The described first sound tone signal that acquisition collects by sound collection unit.
Specifically, namely every Preset Time interval, such as 10min, 20min etc., produce a triggering command, when receiving triggering command, just loud speaker is adjusted.
After obtaining first sound tone signal based on step S101, just can perform step S102, that is: described first sound tone signal is analyzed, obtain the first information of the first parameter;
In specific implementation process, the first parameter in described step S102 is specially the frequency response curve information of loud speaker, and so-called frequency response specifically refers to stereo set for the reduction characteristic of the waveform signal of different frequency composition.Desirable frequency response curve should be straight line, is the situation of distortion sound that do not exist completely in this case.But in actual conditions, all can there is the situation of distortion in the sound that general loud speaker sends, so the frequency response curve that different loud speakers can be corresponding different.And under different environment, identical loud speaker, frequency response curve is also different, such as: the in the situation that at environmental noise, lower and room being smaller, the frequency response curve of loud speaker may more approach straight line; And environmental noise is higher, the frequency response curve of loud speaker may be more crooked.
Suppose, as shown in Figure 3 a, under current environment, the frequency response curve 301a of loud speaker, wherein, abscissa is that frequency (Hz), ordinate are response (dB), namely the sound based on different frequency has different response effects.As can be seen from the figure, this frequency response curve non-straight, as can be seen here, under current environment, loud speaker does not reach optimal response effect.
After obtaining the first parameter information based on step S102, just can perform step S103, that is: judge whether the described first information matches with parameter preset information, wherein, described parameter preset information is specially under default environment, the parameter information obtaining based on described standard voice signal;
In one embodiment, this default environment is specially: environmental noise value is less than the first preset value, sound refractive index is less than the environment that the second preset value and sound reflection rate are less than the 3rd preset value, such as: if environmental noise value is 12dB, sound refractive index is 0.1, sound reflection rate is 0.05, and the first preset value is 15dB, the second preset value is 0.2, the 3rd preset value is 0.2, because all meeting, these three environmental parameter values of environment pre-conditionedly illustrate that so this environment is for default environment, ideally, default environment should be not have the environment of noise completely, but due to generally, the environment that can not existence there is no environmental noise completely, so as long as environmental noise is less, in another embodiment, described default environment is specially: environmental noise value is less than the first preset value and room-size is less than a default big or small environment.
In one embodiment, the parameter information of this standard voice signal is the frequency response curve of this loud speaker under default environment, and this frequency response curve can obtain in the following way:
Under described default environment, by the described loud speaker output standard voice corresponding with standard voice signal;
The second sound signal that acquisition collects by sound collection unit, described second sound signal is that described electronic equipment is less than second sound signal corresponding to the second sound that second environment sound under the environment of the first preset value and described standard voice are mixed to form in environmental noise value;
Described second sound signal is analyzed, obtained described parameter preset information.
Specifically, namely under standard environment, such as: environmental noise is less than in the situation of a preset value, by standard voice corresponding to this loud speaker outputting standard voice signal, then by voice collection device, gather second sound signal corresponding to the second sound that this standard voice and ambient sound mix; Then this second sound signal is passed through to the signal processor in electronic equipment, such as audio decoder, such as microprocessor is processed, then, just can obtain the frequency response curve of this loud speaker under standard environment.
Suppose, as shown in Figure 3 b, under standard environment, the frequency response curve 301b of loud speaker, as can be seen from the figure, and this frequency response curve non-straight, as can be seen here, under standard environment, loud speaker has reached to optimal response effect.
In one embodiment, this standard frequency response curve 301b is stored in described electronic equipment, by this electronic equipment, is being produced when initial, directly obtains; In another embodiment, this standard frequency response curve 301b is stored in network side, the standard frequency response curve of the loud speaker that this network side comprises various electronic, and this electronic equipment can therefrom be selected suitable frequency response curve.
In specific implementation process, obtaining under this electronic equipment current environment, after the first frequency response curve 301a of loud speaker, just can recall standard frequency response curve 301b, wherein, more identical between the first frequency response curve 301a and standard frequency response curve 301b, just illustrate between these two kinds and more mate, the two kinds of frequency response curves that obtain above of take are example, as shown in Figure 3 c, it is the schematic diagram of the first frequency response curve 301a and standard frequency response curve 301b coupling, can see publish picture between the first frequency response curve 301a and standard frequency response curve 301b very major part do not overlap, wherein between region 302a and region 302c, substantially do not overlap, region 302b overlaps.
In one embodiment, when the first frequency response curve 301a and standard frequency response curve 301b complete when overlapping, the first frequency response curve 301a and standard frequency response curve 301b are described, and the match is successful; And in another embodiment, when the fluctuation between the first frequency response curve 301a and standard frequency response curve 301b is in preset range, the first frequency response curve 301a and standard frequency response curve 301b are just described, and the match is successful.
After judging based on step S103, just can perform step S104, that is: when described first information discord parameter preset information matches, the output parameter of described loud speaker is adjusted to second output parameter different from described the first output parameter from the first output parameter.
In the present embodiment, the output parameter of this loud speaker is exactly the frequency response curve of this loud speaker, in Fig. 3 c, can find out, between region 302a and region 302c, between the first frequency response curve 301a and the second frequency response curve 301b and misfit, so, to adjust the first frequency response curve 301a of this area segments, to draw high lower than the part of standard frequency response curve 301b, and the part higher than standard frequency response curve 301b is reduced, the schematic diagram of the first frequency response curve 301a of Fig. 3 d for the first frequency response curve 301c after adjusting and before adjusting, as can be seen from Figure, the the first frequency response curve 301c adjusting is very straight, namely loud speaker can obtain best response effect.
In another embodiment, after guaranteeing to adjust frequency response curve, the response effect that loud speaker obtains is best response effect, after the first frequency response curve 301a is adjusted into the second frequency response curve 301c, as shown in Figure 4, can also continue to carry out following steps:
S401: the second information that continues to obtain described the first parameter;
After obtaining the second information based on step S401, just can perform step S402, that is: judge whether described the second information matches with parameter preset information; If the match is successful, turn to S403; If mate unsuccessfully, turn to S404;
S403: the described output parameter that keeps described loud speaker is described the second output parameter;
S404: the described output parameter of described loud speaker is adjusted to three output parameter different from described the second output parameter from described the second output parameter, and turn to S401.
Specifically, namely after the frequency response curve of this loud speaker is adjusted into 301c, continue by loud speaker outputting standard voice signal, then by voice collection device, gather the morbid sound of standard voice signal and ambient sound, obtain frequency response curve, judge whether this frequency response curve mates with standard frequency response curve 301b, if the match is successful, illustrate that loud speaker has obtained optimal response effect, do not need so the frequency response curve of loud speaker to adjust again; And if mate unsuccessfully, illustrate that loud speaker does not obtain optimal response effect, thereby will frequency response curve be continued to adjust, until the match is successful.
