| Abstract: | A new type of exponential catenary composite horn is designed by equivalent circuit method , and the mathematical expressions of the frequency equation and amplification factor of the composite horn are obtained by using equivalent circuit theory．The resonant length and amplification coefficient of the new type of composite horn are solved by MATLAB software , and the design of the horn is optimized and the finite element analysis is carried out．The results show that the amplification factor of the horn before and after optimization has increased by １３．５％ , which provides ideas for the design of better performance horns． |
