CDBM-Chengdu Broadcast Media is a branch of Chengdu Radio and Television Station, covering concerts, large-scale live broadcasts, music festivals and so on. It is a media organization that simultaneously takes into account the output of traditional broadcast content, the output of various kinds of integrated media content related to sound, and the planning and operation of projects. Radio is "sound" and media is "lens". My design idea is to make sound and lens graphical, and express these two elements together with a simple and same figure. Chengdu Broadcast Media can be heard and seen by more people through constantly expanding "sound" and "lens", by this way to express the infinite possibilities of Chengdu Broadcast Media.
