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.

Abstract

The invention provides a preparation system and a preparation method for a sound intermediate frequency function in physics and relates to the field of multimedia teaching. According to the preparation method for the sound intermediate frequency function in physics provided by the invention, a polar coordinate system is adopted, screen limit is broken through, a whole chapter is completely shown to an operator, various function waveforms can be set according to requirements and voice frequency wave information can be directly displayed. The preparation method mainly comprises the following steps: preparing a basic syllable, making music, adding a music effect (or setting no music effect), performing reverberation treatment, controlling with buttons, and playing music. According to the invention, two characteristics of physical sound teaching and music teaching are combined for helping a producer to fully understand audio features, relation of rising tone, falling tone and original sound, and methods for end syllable treatment, stereo treatment, and the like, so that students can understand knowledge about music theory and direct display of intermediate frequency function in physics. According to the invention, programming tools, such as C language and java language, can be adopted for replacing a geometer 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.
