Research On The Design Of B-flat Piston Trumpet Based On Usability Theory

With the deepening of reform and opening up,people's interest in western music is also rising rapidly as well.In the entire Western music system,trumpet plays a very important role among all kind of western brass instruments.As the most popular brass instruments,learning and playing trumpet can cultivate sentiment.However,the domestic trumpet production and research and development level has been maintained at a low level for a long time,and the domestic production of trumpet quality is difficult to meet the growing needs of the people.This is an urgent request for the developers of trumpet.In this paper,the usability design method is used to study the usability of the B-flat piston trumpet performance.Research literature,field visits,to understand the history,type,structure,pronunciation and the latest research at home and abroad of trumpet,the development of research topics and product positioning.Then through the questionnaire,interviews,etc.,we carried out a detailed study on the users of good performance of trumpet,including user characterization,user action model and thinking model to establish the use of scenes and tasks set to develop a evaluation system and evaluation criteria for the good performance of trumpet.Also the experimental study on the two main technological factors affecting the performance of the trumpet is carried out.Combining the usability test and the analytic hierarchy process,the optimal weight of each usability index and the best craft for good trumpet performance are obtained.Based on experimental research and usability test to develop the final program,we evaluate it with the most popular trumpets in the same grade for comparison by both user and expert evaluation.The research on the usability of trumpet performance is put forward by scientific research ideas and practice methods,which can improve the performance of domestic trumpet,and establish scientific evaluation system of trumpet performance.It also provides a reference to the ideas and methods.
