detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 1, a first embodiment of a sound processing method of the present invention is proposed. The method includes the following steps:

S11. Detect a pressure value at which the terminal is pressed.

Optionally, the terminal has a touch surface, and a pressure sensor can be disposed under the touch surface, and the pressure value of the touch surface being pressed is detected by the pressure sensor. The touch surface can be a screen or other surface for pressing.

Optionally, the screen of the terminal is a pressure screen, and the pressure value of the user pressing the screen is detected through the pressure screen.

S12. Match the value of the timbre parameter corresponding to the detected pressure value according to the correspondence between the preset pressure and the timbre parameter.

The correspondence between the pressure and the timbre parameters is stored in the terminal, and the correspondence between the pressure and the timbre parameters includes the correspondence between at least two sets of pressure value intervals and timbre parameter values, that is, each pressure value interval corresponds to a timbre parameter value, and the terminal judges the detection. The range of pressure values into which the pressure value falls is obtained, and the value of the timbre parameter corresponding to the interval of the pressure value falling in is obtained, and the timbre parameter value is the timbre parameter value corresponding to the detected pressure value.

In some embodiments, the correspondence of pressure to timbre parameters can be represented by a table as shown in FIG. Among them, a total of n groups of one-to-one corresponding pressure value interval and timbre parameter value data, the pressure value interval includes

A total of n, the tone parameter values include S1, S2, ..., Sn a total of n. Where n ≥ 2, M is the set maximum pressure value, usually the maximum pressure value that the terminal can detect.

In order to improve the accuracy of the matching, buffers can be set between two adjacent pressure value intervals. At this time, the correspondence between the pressure and the timbre parameters can be represented by a table as shown in FIG. Among them, a total of n groups of one-to-one corresponding pressure value interval and timbre parameter value data, the pressure value interval includes

A total of n, the tone parameter values include S1, S2, ..., Sn a total of n. Where n ≥ 2, M is the set maximum pressure value, usually the maximum pressure value that the terminal can detect, k is the buffer between the adjacent two pressure value intervals, which is a constant, the size can be as needed set up. At this time, when the detected pressure value falls within the buffer zone between two adjacent pressure value intervals (ie, the pressure value does not fall within any one of the pressure value intervals), the detection result may be discarded, or the detection result may be discarded. The pressure value is calculated in the previous pressure value interval or the latter pressure value interval.

Optionally, the timbre parameter includes a frequency, and the corresponding relationship between the pressure and the frequency is stored in the terminal, and the terminal matches the frequency value corresponding to the detected pressure value according to the correspondence between the pressure and the frequency. That is to say, the terminal adjusts the frequency of playing the sound source according to the pressing strength of the user, thereby changing the tone color thereof.

For example: suppose the frequency filter of the terminal is a frequency multiplier of 50 Hz, and the pressure value detectable by the pressure screen of the terminal ranges from (0 to M) Newton (N), so the pressure value of (0 to M) Newton will be The range is divided into 6 sections, and the interval size of each section is

Newton, the corresponding relationship between pressure and frequency is shown in Figure 4. Different terminals can also set different pressure and frequency correspondences according to their characteristics, as well as the amplitude and range of frequency.

That is to say, the terminal adjusts the loudness of the playing sound source according to the pressing strength of the user, thereby changing the sound color thereof.

For example: suppose the loudness value is expressed in loudness level, and the loudness level is set to level 6. The pressure value detectable by the pressure screen of the terminal ranges from (0 to M) Newton (N), so (0 to M) Newton The pressure value range is divided into 6 intervals, and the size of each interval is

Newton, the corresponding relationship between the set pressure and loudness is shown in Figure 5. Different terminals can also set different correspondences between pressure and loudness and the actual size of loudness according to their characteristics. Assume that the detected pressure value falls within the pressure value interval

Within the match, the corresponding loudness level is matched to level 4.

Optionally, the timbre parameter includes a frequency and a loudness, and the correspondence between the pressure and the frequency and the correspondence between the pressure and the loudness are stored in the terminal. The terminal matches the frequency value corresponding to the detected pressure value according to the correspondence between the pressure and the frequency; and matches the loudness value corresponding to the detected pressure value according to the correspondence between the pressure and the loudness.

In some embodiments, the terminal continuously collects the pressure value for a period of time. When the collected pressure values fall within the same pressure value interval, the timbre parameter value corresponding to the pressure value interval is selected to be a desired timbre parameter value. When the collected pressure values fall into different pressure value intervals, the timbre parameter value corresponding to the pressure value range in which the most pressure value falls is selected to be the desired timbre parameter value. Then, the tone color parameter of the playback source is adjusted to the selected tone parameter value and played.
