Trumpet is very common in daily life and plays an important role. With the development of science and technology, the research on the physical characteristics and performance of the horn has reached a new level. For a long time, the research on electrical loudspeaker and other electronic products is more popular, while the design of horn which can optimize the human voice transmission is less involved. Aiming at this research direction, this paper introduces in detail the influence of horn parameters on the sound output of human voice frequency. Based on the theoretical calculation results, the sound horn with good performance is manufactured by using 3D printing technology, and relevant experiments are designed. Combined with the theoretical and simulation results, the performance of the horn with different parameters is explored to optimize the voice transmission to distant listeners, which are helpful to further understand the performance of the horn, are applied in various fields.
