Detailed ways

The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should also be noted that, for ease of description, only some, but not all, of the structures related to the present invention are shown in the drawings.

Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as a process or method depicted as a flowchart. Although the flowcharts describe the various steps as a sequential process, many of the steps can be implemented in parallel, concurrently, or concurrently. In addition, the order of the steps can be rearranged. The process may be terminated when its operation is completed, but may also have additional steps not included in the figures. The processing may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

FIG. 1 is a schematic flowchart of a volume adjustment method according to an embodiment of the present invention. The method may be implemented by a volume adjustment apparatus provided by an embodiment of the present invention, where the apparatus may be implemented by software and/or hardware, and may be integrated into a mobile terminal. in. As shown in Figure 1a, the method includes:

S101. Acquire a spectrum curve of the sound source file when a sound source file playback trigger event is detected.

The audio source file may be an audio and video file, such as a ringtone, a prompt tone, a music, and a video file of the mobile terminal. The playing trigger event may be a start playing operation clicked by the user, clicking a music and a video file, etc., or the mobile terminal may detect that the communication information is received, and monitoring the system time to reach a preset alarm time.

The spectral curve of the source file may be the relationship between frequency and amplitude or the relationship between frequency and decibel in the sound information of the source file. FIG. 1b is a schematic diagram of a spectrum curve according to an embodiment of the present invention. As shown in FIG. 1b, the abscissa may be the frequency of the sound information of the sound source file, and the ordinate may be the volume information corresponding to each frequency, and may be decibel. Said. In the example of Figure Ib, the spectral curve exhibits a relatively uniform amplitude level after the frequency exceeds 40 Hz. Since the hearing range of the human ear is between 20 Hz and 20 kHz, and there is a normal auditory response after the frequency exceeds 40-50 Hz, that is, when the frequency is less than 40 Hz, the user is not sensitive to the hearing of the sound. Moreover, for the sound source file, if the frequency range exceeds the range of 20 Hz to 20 kHz, the human ear is inaudible, although it can be set, but it is of little significance for the ears to hear.

S102. Determine an adjustment parameter of the spectrum curve according to a frequency response curve of the human ear.

Among them, the frequency response curve of the human ear is the response curve of the human ear to different frequencies, that is, even if the sound emitted by the mobile terminal is constant at each frequency, the volume of the human ear sounds gradually with frequency. The change is roughly manifested by the relatively low volume of the low frequency and the relatively high volume of the high frequency. FIG. 1c is a schematic diagram of a human ear frequency response curve according to an embodiment of the present invention. As shown in FIG. 1c, for a frequency range between 40 Hz and 300 Hz, the response of the human ear to the frequency is relatively low, and the frequency range is 300 Hz. Between 2 kHz, the human ear's response to frequency is relatively stable. In the frequency range between 2 kHz and 3 kHz, the human ear's response is relatively reduced, but between 3 kHz and 10 kHz, the human ear responds rapidly to frequency. Raise, that is, if the human ear hears a constant amplitude of the sound frequency from 3 kHz to 10 kHz, it will sound louder and louder. In addition, it can be seen from FIG. 1c that the response of the human ear to different frequencies can be up to nearly 30 Db, so that the solution for adjusting the volume of the mobile terminal according to the human ear curve according to the embodiment of the present invention can solve this technology. problem.

The adjustment parameter of the spectrum curve may include a frequency interval parameter, and may also include an adjustment parameter corresponding to each frequency interval. The frequency interval parameter may be to divide the spectrum curve into at least one Frequency range. For the above example, according to the frequency response curve of the human ear, 40Hz-200Hz can be divided into one frequency interval, 200Hz-2kHz is divided into one frequency interval, and 2kHz-10kHz is divided into one frequency interval, thus dividing three frequencies. Interval. If the current design requirement is to reduce the response of the high frequency interval, then only one frequency interval of 4 kHz - 10 kHz can be divided.

Multiply the spectral curve in the frequency interval by a certain adjustment factor, or add a certain adjustment factor. Combined with the above example of dividing into three frequency intervals, it is explained that the adjustment coefficient can be determined as follows: if a frequency interval of 200 Hz - 2 kHz can be determined as a frequency interval without adjustment, since the frequency response curve is basically within the frequency interval range Smooth fluctuations within a certain range, it can be considered that the human ear has a substantially consistent sound frequency response within the frequency range. In the three frequency intervals, it is only necessary to adjust for the first frequency interval and the third frequency interval, and in the frequency range of 40 Hz-200 Hz, according to the difference between the frequency interval and the second frequency interval, for example, On the basis of this frequency interval, the spectral curve of the sound source file is increased by 10Db; or multiplied by the adjustment coefficient, for example, the spectral curve of the sound source file can be multiplied by the adjustment factor of 1.2 on the basis of the frequency interval. For the third frequency interval, according to the difference between the second frequency interval and the second frequency interval, the mean frequency coefficient may be divided or subtracted, and the third frequency interval is divided or subtracted from the mean value coefficient, and the obtained is not completely close to the second frequency. The frequency response level of the interval, but can be a coefficient within a range that is substantially imperceptible to the human ear. In addition, a dynamic adjustment coefficient can also be determined according to the curve of the human ear, so that the human ear has the same level of response to the spectral curve of the adjusted source file.

S103. Adjust a spectrum curve of the sound source file according to the adjustment parameter.

According to the adjustment parameters, including the adjustment interval and the adjustment coefficient, the spectral curve of the sound source file is adjusted accordingly, thereby obtaining a volume level that the human ear can respond to the frequency response in the entire audible range.

On the basis of the above technical solution, optionally, determining the adjustment parameter of the spectrum curve according to a frequency response curve of the human ear, including: determining at least one adjustment frequency interval according to a frequency response curve of the human ear; determining the The adjustment parameter of the adjusted frequency interval of the spectral curve. Among them, the number of division adjustment frequency intervals can be determined according to the user's accuracy requirement for the volume response. The more the frequency interval, the more accurate the spectrum curve of the obtained source file in the human ear is. The advantage of this setting is that Different adjustment frequency intervals can be determined according to different needs of users in response to the needs of different users.

The advantage of this setting is that the adjustment factor of different frequency intervals can be determined according to the response level of the human ear to the frequency in the human ear curve, and then the spectrum curve of the frequency interval is adjusted, which can be adjusted in the frequency division interval. Increasing the calculation speed and reducing the calculation amount of the mobile terminal, thereby improving the response speed of the mobile terminal.

As shown in FIG. 2b, the abscissa is the same as the abscissa of the human ear frequency response curve, and the ordinate is the adjustment magnification. It can be seen from the frequency adjustment magnification curve that the response of the human ear to the frequency is a relatively low frequency range between 40 Hz and 300 Hz, and the magnification can be nearly 1.2 times; the response of the human ear to the frequency is relatively stable. In the frequency range between 300 Hz and 2 kHz, the magnification can be close to 1.0 times; the response of the human ear to the frequency is a frequency interval between 2 kHz and 10 kHz, and the magnification can be increased first and then decreased. It is reduced to nearly 0.7 times at 10 kHz.
