In this paper, a new type of instrument is designed for the purpose of localizing the sound source. It is a relatively compact structure. This bionic structure is to mimic the localization function of the ears of the parasitoid fly Ormia ochracea. It consists of three elastic diaphragms, three bars which are connected to the diaphragms, and some other mechanical components. Analysis of this structures dynamic behavior shows that the incident angles of the sound have special relationship to the responses of this instrument, and the incident angles can be estimated by detecting the vibrations of the three elastic diaphragms.
