Referring to fig. 1 to 4 together, an embodiment of the invention provides a method for optimizing audio performance of a mobile terminal. The mobile terminal 10 includes an audio device 12. Audio device 12 includes a microphone 122 and a speaker 124. The microphone 122 is used to convert acoustic signals into electrical signals. The speaker 124 is used to convert the electrical signals to acoustic signals for broadcast. The optimization method comprises the following steps:
s10: periodically acquiring an audio signal of a loudspeaker 124 through a microphone 122 in a preset mode and drawing a real-time frequency response curve;
s20: judging whether the real-time frequency response curve is a fault frequency response curve or not according to the real-time frequency response curve and the reference frequency response curve;
s30: judging whether the performance of the audio device 12 has a fault according to the fault frequency response curve; and
s40: if the performance of the audio device 12 has a fault, the corresponding electrical signal of the audio device 12 is corrected.
Referring to fig. 2 to 4, an embodiment of the invention provides a mobile terminal 10. The mobile terminal 10 includes an audio device 12 and a processor 14. Audio device 12 includes a microphone 122 and a speaker 124. The microphone 122 is used to convert acoustic signals into electrical signals. The speaker 124 is used to convert the electrical signals to acoustic signals for broadcast. The embodiment of the present invention will be described by taking the mobile terminal 10 as a mobile phone as an example. The method for optimizing the audio performance of the mobile terminal according to the embodiment of the present invention may be applied to the mobile terminal 10 according to the embodiment of the present invention. For example, the microphone 122 may be used to perform the method in S10, and the processor 14 may be used to perform the methods in S20, S30, and S40.
That is, the microphone 122 may be used to periodically capture audio signals from the speaker 124 in a predetermined pattern and to plot a real-time frequency response curve. The processor 14 may be configured to: judging whether the real-time frequency response curve is a fault frequency response curve or not according to the real-time frequency response curve and the reference frequency response curve; judging whether the performance of the audio device 12 has a fault according to the fault frequency response curve; and modifying the electrical signal corresponding to audio device 12 in the presence of a performance failure of audio device 12.
According to the method for optimizing the audio performance of the mobile terminal and the mobile terminal 10, disclosed by the embodiment of the invention, the real-time frequency response curve of the audio signal is periodically obtained to detect whether the performance of the audio device 12 has a fault or not, and the performance of the audio device 12 is corrected in time when the performance of the audio device 12 has the fault, so that the tone quality is not deteriorated. In addition, the method for optimizing the audio performance of the mobile terminal according to the embodiment of the present invention collects the audio signal of the speaker 124 through the microphone 122 built in the mobile terminal 10, that is, the performance of the audio device 12 does not need to be detected by connecting the external microphone 122 or a related audio detecting device, which is simple and convenient.
In the embodiment of the present invention, determining whether there is a failure in the performance of the audio device 12 according to the failure frequency response curve includes: and judging whether the performance of the microphone 122 has a fault according to the fault frequency response curve or judging whether the performance of the loudspeaker 124 has a fault according to the fault frequency response curve. Modifying the electrical signal corresponding to audio device 12 when there is a performance failure of audio device 12 includes: the electrical signal corresponding to the microphone 122 is corrected when there is a failure in the performance of the microphone 122, and the electrical signal corresponding to the speaker 124 is corrected when there is a failure in the performance of the speaker 124. The manner of modifying the electrical signal corresponding to audio device 12 may be: the electrical signal or audio parameters (e.g., power amplifier gain, etc.) are modified in a software manner so that the real-time frequency response curve is consistent with the reference frequency response curve.
In some embodiments, the predetermined mode includes at least one of a power-on mode, a power-off mode, and a talk mode. The periodicity may be one or more times.
For example, the method for optimizing the audio performance of the mobile terminal according to the embodiment of the present invention may collect the audio signal of the speaker 124 in each of the processes of powering on and powering off the mobile phone (i.e. the power-on mode and the power-off mode). It will be appreciated that the speaker 124 will typically play a particular piece of music each time the phone is turned on and off (default phone is in a non-silent state, and when the user sets the phone to not play music during power on and off, the user may choose to collect audio signals in a talk mode or other modes). Referring to fig. 4, in the optimization method, when the mobile phone leaves the factory, the microphone 122 may collect an audio signal corresponding to a specific music played by the speaker 124 and draw a frequency response curve, where the frequency response curve may be used as a reference frequency response curve. After the mobile phone leaves the factory and in the process of using the mobile phone by a user, the microphone 122 collects the audio signal of the speaker 124 in the process of turning on and off the mobile phone each time so as to draw a real-time frequency response curve. Thus, after the performance of the audio device 12 is judged according to the real-time frequency response curve and the reference frequency response curve and the electrical signal of the audio device 12 is corrected, the audio signal collected by the subsequent microphone 122 can be consistent with the audio signal collected when the device leaves the factory, and the tone quality of the audio device 12 is ensured.
It should be noted that when the predetermined mode includes a call mode, the call mode is a play-out mode of a call, and thus, the microphone 122 is facilitated to collect an audio signal of the speaker 124.
Referring to fig. 5, in some embodiments, the frequency response curve has a frequency on the abscissa and a sound pressure on the ordinate. The step (i.e., S20) of determining whether the real-time frequency response curve is the fault frequency response curve according to the real-time frequency response curve and the reference frequency response curve includes:
s21: selecting a preset number of frequency coordinate points;
s22: comparing the real-time sound pressure value of the real-time frequency response curve under the frequency coordinate point with the reference sound pressure value of the reference frequency response curve; and
s23: and when the difference between the preset number of real-time sound pressure values and the corresponding reference sound pressure values is larger than a preset value, judging that the real-time frequency response curve is a fault frequency response curve.
In some embodiments, the frequency response curve has a frequency on the abscissa and a sound pressure on the ordinate. The processor 14 may be configured to execute the methods of S21, S22, S23.
That is, the processor 14 is further operable to: selecting a preset number of frequency coordinate points; comparing the real-time sound pressure value of the real-time frequency response curve under the frequency coordinate point with the reference sound pressure value of the reference frequency response curve; and when the difference between the preset number of real-time sound pressure values and the corresponding reference sound pressure values is larger than a preset value, judging that the real-time frequency response curve is a fault frequency response curve.
For example, referring to fig. 4, the predetermined number may be 10 (in practical cases, the predetermined number may be much larger than 10, and here, the predetermined number is 10 for example). The predetermined number of frequency coordinate points are respectively: 20HZ, 50HZ, 100HZ, 200HZ, 500HZ, 1kHZ, 2kHZ, 5kHZ, 10kHZ and 20 KHZ. The optimization method respectively calculates the difference between the real-time sound pressure value of the real-time frequency response curve and the reference sound pressure value of the reference frequency response curve at the frequency coordinate points, and when the difference between the real-time sound pressure value and the reference sound pressure value is larger than a preset value (for example, the difference is larger than 2.5) at the 10 frequency coordinate points, the real-time frequency response curve is judged to be a fault frequency response curve. And if the difference between the real-time sound pressure value and the reference sound pressure value is larger than the preset value only at 9 frequency coordinate points, and the difference between the real-time sound pressure value and the reference sound pressure value is smaller than the preset value at 1 frequency coordinate point, judging that the real-time frequency response curve is not a fault frequency response curve. In the embodiment of the present invention, the optimization method determines whether there is a failure in the performance of the audio device 12 according to whether the real-time frequency response curve is a failure curve.
Referring to fig. 6, in some embodiments, the real-time frequency response curve includes a plurality of segments acquired at different time points. The step of determining whether there is a failure in the performance of the audio device 12 according to the failure frequency response curve (i.e., S30) includes:
s31: when the number of the fault frequency response curves is larger than the preset number, the performance of the audio device 12 is judged to have faults.
In some embodiments, the real-time frequency response curve includes a plurality of segments acquired at different points in time. The processor 14 is operable to execute the method in S31.
That is, processor 14 may be further configured to determine that there is a failure in the performance of audio device 12 when the number of failure frequency response curves is greater than a predetermined number.
For example, referring to fig. 7, the real-time frequency response curves include three real-time frequency response curves obtained at three time points of 18:06, 18:07, and 18:08, where the three real-time frequency response curves are a real-time frequency response curve 1, a real-time frequency response curve 2, and a real-time frequency response curve 3. The predetermined number may be 10, and the predetermined number of frequency coordinate points are respectively: 20HZ, 50HZ, 100HZ, 200HZ, 500HZ, 1kHZ, 2kHZ, 5kHZ, 10kHZ and 20 KHZ. The optimization method respectively calculates the difference between the real-time sound pressure value of each real-time frequency response curve and the reference sound pressure value of the reference frequency response curve under the frequency coordinate points, and when the difference between the real-time sound pressure value and the reference sound pressure value is larger than a preset value under the 10 frequency coordinate points, the real-time frequency response curve is judged to be a fault frequency response curve. And if the difference between the real-time sound pressure value and the reference sound pressure value is larger than the preset value only at 9 frequency coordinate points, and the difference between the real-time sound pressure value and the reference sound pressure value is smaller than the preset value at 1 frequency coordinate point, judging that the real-time frequency response curve is not a fault frequency response curve. After judging whether each real-time frequency response curve is a fault frequency response curve by the method, judging whether the number of the fault frequency response curves is larger than the preset number, for example, if the preset number is 1, when any two or more than two of the real-time frequency response curve 1, the real-time frequency response curve 2 and the real-time frequency response curve 3 are fault frequency response curves, judging that the performance of the audio device 12 has faults. In the embodiment of the present invention, the optimization method determines that there is a failure in the performance of the audio device 12 according to that, in the multiple real-time frequency response curves obtained at different time points, the number of failure frequency response curves is greater than the predetermined number (for example, the predetermined number is 2), so that, compared with a structure that only one real-time frequency response curve is used for determination, erroneous determination can be avoided, and the determination result is more accurate.
Referring to fig. 8, in some embodiments, the abscissa of the frequency response curve is frequency, the ordinate is sound pressure, and the real-time frequency response curve includes a plurality of segments acquired at different time points. The step (i.e., S20) of determining whether the real-time frequency response curve is the fault frequency response curve according to the real-time frequency response curve and the reference frequency response curve includes:
s24: selecting a frequency coordinate point;
s25: calculating the difference between the real-time sound pressure value of each real-time frequency response curve and the reference sound pressure value of the reference frequency response curve at the frequency coordinate point;
s26: judging whether the difference between the real-time frequency response curve acquired later and the reference frequency response curve is in a gradually increasing trend compared with the difference between the real-time frequency response curve acquired earlier and the reference frequency response curve; and
s27: and if the number of the corresponding frequency coordinate points is gradually increased and is larger than the preset number, judging that the real-time frequency response curve is a fault frequency response curve.
In some embodiments, the frequency response curve has a frequency on the abscissa and a sound pressure on the ordinate, and the real-time frequency response curve includes a plurality of segments acquired at different time points. The processor 14 may be used to execute the methods in S24, S25, S26, and S27.
That is, the processor 14 is further operable to: selecting a frequency coordinate point; calculating the difference between the real-time sound pressure value of each real-time frequency response curve and the reference sound pressure value of the reference frequency response curve at the frequency coordinate point; judging whether the difference between the real-time frequency response curve acquired later and the reference frequency response curve is in a gradually increasing trend compared with the difference between the real-time frequency response curve acquired earlier and the reference frequency response curve; and if the real-time frequency response curve is gradually increased and the number of the corresponding frequency coordinate points is larger than the preset number, judging that the real-time frequency response curve is a fault frequency response curve.
For example, referring to fig. 7, the real-time frequency response curves include three real-time frequency response curves acquired at 19 days in 11 months, 20 days in 11 months, and 21 days in 11 months, and the three real-time frequency response curves are a real-time frequency response curve 1, a real-time frequency response curve 2, and a real-time frequency response curve 3, respectively. The selected frequency coordinate points may be: 20HZ, 50HZ, 100HZ, 200HZ, 500HZ, 1kHZ, 2kHZ, 5kHZ, 10kHZ and 20 KHZ. The optimization method respectively calculates the difference between the real-time sound pressure value of each real-time frequency response curve and the reference sound pressure value of the reference frequency response curve under the frequency coordinate points. Assuming that differences between a real-time sound pressure value of the real-time frequency response curve and a reference sound pressure value of the reference frequency response curve at the same frequency coordinate point acquired at 19 th of 11 th, 20 th of 11 th, and 21 th of 11 th are respectively a first difference, a second difference, and a third difference, when the first difference, the second difference, and the third difference are in a gradually increasing trend at frequency coordinate points greater than a predetermined number (for example, the predetermined number may be 7), the real-time frequency response curve is determined as a fault frequency response curve, that is, the real-time frequency response curve 1, the real-time frequency response curve 2, and the real-time frequency response curve 3 are determined as fault frequency response curves. For example, at 20HZ, a first difference between a real-time sound pressure value-15 of the real-time frequency response curve 1 and a reference sound pressure value-11.25 of the reference frequency response curve is 3.75, a second difference between a real-time sound pressure value-16 of the real-time frequency response curve 2 and a reference sound pressure value-11.25 of the reference frequency response curve is 4.75, and a third difference between a real-time sound pressure value-16.5 of the real-time frequency response curve 3 and a reference sound pressure value-11.25 of the reference frequency response curve is 5.25, which indicates that the first difference, the second difference and the third difference at the frequency coordinate point of 20HZ are in a gradually increasing trend. Similarly, as can be seen from fig. 7, the first difference, the second difference and the third difference at two frequency coordinate points of 1KHZ and 10KHZ are gradually increased. If the predetermined number is 2, the real-time frequency response curve can be determined to be a fault frequency response curve. In the embodiment of the present invention, the optimization method determines that there is a failure in the performance of the audio device 12 when it is determined that the performance of the audio device 12 gradually deteriorates according to the multiple real-time frequency response curves obtained at different time points. In this way, the electrical signal of audio device 12 can be corrected in time, preventing further degradation of the performance of audio device 12.
Referring to fig. 2, 3, and 9, in some embodiments, the microphone 122 includes a primary microphone 1222 and a secondary microphone 1224. The real-time frequency response curves include a first frequency response curve plotted by periodically capturing audio signals from the speaker 124 in the predetermined mode via the primary microphone 1222 and a second frequency response curve plotted by periodically capturing audio signals from the speaker 124 in the predetermined mode via the secondary microphone 1224. The step of determining whether there is a failure in the performance of the audio device 12 according to the failure frequency response curve (i.e., S30) includes:
s32: when the first frequency response curve is a fault frequency response curve and the second frequency response curve is not a fault frequency response curve, it is determined that the performance of the main microphone 1222 has a fault; and/or
S33: when the first frequency response curve is not the fault frequency response curve and the second frequency response curve is the fault frequency response curve, it is determined that there is a fault in the performance of the secondary microphone 1224.
Referring to fig. 2 and 3, in some embodiments, the microphone 122 includes a primary microphone 1222 and a secondary microphone 1224. The real-time frequency response curves include a first frequency response curve plotted by periodically capturing audio signals from the speaker 124 in the predetermined mode via the primary microphone 1222 and a second frequency response curve plotted by periodically capturing audio signals from the speaker 124 in the predetermined mode via the secondary microphone 1224. The processor 14 is operable to execute the methods in S32 and S33.
That is, the processor 14 is further operable to: when the first frequency response curve is a fault frequency response curve and the second frequency response curve is not a fault frequency response curve, it is determined that the performance of the main microphone 1222 has a fault; and/or when the first frequency response curve is not a fault frequency response curve and the second frequency response curve is a fault frequency response curve, then the performance of the secondary microphone 1224 is judged to be faulty.
In the embodiment of the present invention, the number of the sub microphones 1224 may be one or more. When the number of the sub microphones 1224 is plural, the real-time frequency response curve includes a first frequency response curve which is plotted by periodically collecting the audio signal of the speaker 124 in the predetermined mode by the main microphone 1222 and a plurality of second frequency response curves which are respectively plotted by periodically collecting the audio signal of the speaker 124 in the predetermined mode by the plurality of sub microphones 1224. S32 includes: when the first frequency response curve is a fault frequency response curve and the second frequency response curves are not fault frequency response curves, it is determined that the performance of the primary microphone 1222 is faulty. S33 includes: when the first frequency response curve is not the failure frequency response curve and a failure frequency response curve exists in the plurality of second frequency response curves, it is determined that a failure exists in the performance of the sub-microphone 1224 corresponding to the second frequency response curve that is the failure frequency response curve.
In the embodiment of the present invention, correcting the electrical signal corresponding to the audio device 12 when there is a failure in the performance of the audio device 12 includes: the electrical signal corresponding to the primary microphone 1222 is modified when there is a failure in the performance of the primary microphone 1222 and the electrical signal corresponding to the secondary primary microphone 1222 is modified when there is a failure in the performance of the secondary primary microphone 1222. In this manner, good performance of the primary 1222 and secondary 1224 microphones may be assured.
Referring to fig. 2, 3 and 10, in some embodiments, the audio device 12 further includes a receiver 126. The real-time frequency response curves include a third frequency response curve obtained by periodically collecting the audio signals of the receiver 126 through the main microphone 1222 in the predetermined mode and plotting, and a fourth frequency response curve obtained by periodically collecting the audio signals of the receiver 126 through the auxiliary microphone 1224 in the predetermined mode and plotting. The step of determining whether there is a failure in the performance of the audio device 12 according to the failure frequency response curve (i.e., S30) includes:
s34: when the first frequency response curve and the second frequency response curve are both fault frequency response curves, and the third frequency response curve and the fourth frequency response curve are not both fault frequency response curves, it is determined that the performance of the speaker 124 has a fault.
