Language is one of the most important communication tool and way of existencesince ancient times, is a symbol system based on voice to convey information. Moreand more people want to have a beautiful voice. In common sense",beautiful voice"should be clear and vivid, can express their willingness.The paper ifrst instructed the improgress in construction and sound system inorder to get "bea”utiful voice,put forward that we can study in the sound sourceinstead of the route of transmission. Summarize From the instrument sound principleto summarize a set of logical model: the sound source, power and the resonator.Position structure of vocal cords are illustrated by ifgure Solid works modelingmethod is proposed, the vibration of the vocal cords and physical model~that voiceis the air through the glottis when the Carmen vortex and vocal resonance, andthrough the ANSYS ifnite element analysis, MATLAB spectrum analysis of the threeaspects and the mathematical derivation of the model is validated, and at the sametime expounds on the "true" and "false" sound controversy--just different parts of thevibration of the vocal cords", really" sound is vocal overall vibration and "false"sound is vocal edge vibration.The breath is the source of the necessary conditions for human survival andvocal airflow, so the phonation and respiration are inseparable. Carmen vortex lfowgenerated through the glottis, low lfow rate can be regarded as "monopole soundsource and velocity when the’’ is’’dipole’’,because the radiation power of the formerthan the latter, so to improve the sound pressure level can not only improve thevelocity of lfow can also be achieved by making full use of monopole reverseradiation pressure.The basic principle is the resonance cavity resonance, including through a sharpincrease in specific frequency voice sound pressure level and on sound vibrationovertone of combination to make rich sound. Through the MATLAB analysis of different singing style draws the conclusion: different singing styles in addition to theuse of breath on the characteristics of the biggest difference is the application of theresonance cavity.The innovation of this paper is put aside the sound transmission from the soundsource, to explore the vocal process and the basic principle of humanity itself, throughthe establishment of model is discussed from the factors affecting the sound quality ofthe physical and mathematical level, and fully certiifed by experiment, provides atheoretical guidance for the foundation of scientiifc sound.
