specific Embodiment approach 1

[0096] Such as image 3 Shown, a kind of audio frequency function production method in physics of the present invention, its specific operation process is as follows:

[0097] Step 1. In the basic syllable module, make the basic syllable according to the sounding principle. The specific operation process is as follows:

[0098] S101: open the geometric sketchpad, construct the basic function: y=m*sin(2πkx);

[0099] In the formula, y is the audio intensity, the unit is decibel (db); m is the audio intensity magnification, no unit; k is the frequency, the unit is Hertz; x is the time value, the unit is second.

[0100] S102: Construct the basic syllable function; according to the k value (frequency value) in Table 1, assign it to the basic function to obtain the basic syllable function, customize different basic syllables according to the basic syllable function, and assign them sound attributes.

[0101] Table 1

[0102] Note Frequency / Hz Note Frequency / Hz ...

specific Embodiment approach 2

[0125] Such as Figure 4 Shown, a kind of audio frequency function production method in physics of the present invention, its specific operation process is as follows:

[0126] Step 1. In the basic syllable module, make the basic syllable according to the sounding principle. The specific operation process is as follows:

[0127] S101: open the geometric sketchpad, construct the basic function: y=m*sin(2πkx);

[0128] In the formula, y is the audio intensity, the unit is decibel (db); m is the audio intensity magnification, no unit; k is the frequency, the unit is Hertz; x is the time value, the unit is second.

[0129] S102: Construct the basic syllable function; according to the k value (frequency value) in Table 1, assign it to the basic function to obtain the basic syllable function, customize different basic syllables according to the basic syllable function, and assign them sound attributes.

[0131] Note Frequency / Hz Note Frequency / Hz ...

specific Embodiment approach 3

[0168] Such as Figure 5 Shown, a kind of audio frequency function production method in physics of the present invention, its specific operation process is as follows:

[0169] Step 1. In the basic syllable module, make the basic syllable according to the sounding principle. The specific operation process is as follows:

[0170] S101: open the geometric sketchpad, construct the basic function: y=m*sin(2πkx);

[0171] In the formula, y is the audio intensity, the unit is decibel (db); m is the audio intensity magnification, no unit; k is the frequency, the unit is Hertz; x is the time value, the unit is second.

[0172] S102: Construct the basic syllable function; according to the k value (frequency value) in Table 1, assign it to the basic function to obtain the basic syllable function, customize different basic syllables according to the basic syllable function, and assign them sound attributes.

Abstract

A system and method for making an audio function in physics, which relate to the field of multimedia teaching. The method for making an audio function in physics according to the present invention adopts the polar coordinate method, breaks through the screen limitation, and presents the entire song completely to the operator In front of you, and can set various function waveforms according to your needs, and intuitively display audio wave information. The main steps are: basic syllable production, music production, adding music effects (music effects may not be set), reverberation processing, button control, and music playback. The present invention combines the two characteristics of physical sound teaching and music teaching, so that producers can fully understand the characteristics of audio, the relationship between tone, falling tone and the original tone, tail sound processing, stereo processing and other methods, so that students can understand both music theory and physics Visual display of audio functions in learning. The present invention can use programming tools such as C language and java language instead of the geometric sketchpad instead of the geometric sketchpad.

Description

technical field [0001] The invention relates to the technical field of multimedia teaching, in particular to an audio function production system and a production method in physics. Background technique [0002] After entering the 21st century, the multimedia teaching system has become popular in various subjects, and music and physics teaching is no exception. The application and popularization of multimedia music and physics teaching system in the field of music and physics has brought a new experience to music and physics teaching, and has become an important teaching tool in music and physics teaching. In the process of teaching, teachers must keep up with the pace of the times, closely integrate emerging technologies with music and physics teaching, and apply them more effectively in the teaching process, so as to promote the continuous improvement of the level and effect of music and physics teaching, and accelerate the transformation of music and physics.
