A simulation device for imitating a bat receiving part and its application method

Abstract

The invention discloses a bat receiving part simulation device and an application method. Through the device, the problem that no research about whether the position of a lower flap of a bat has an influence or not relative to the frequency sweeping function of an external ear of the bat is available in the prior art is solved, and the device has the advantage that state / stateless simulation of abionic external ear lower flap relative to a bionic external ear can be realized. The bat receiving part simulation device comprises a sound wave emitting mechanism, a simulated external ear mechanismand a sound field detection mechanism, wherein the sound wave emitting mechanism is used for generating sound waves; the simulated external ear mechanism is arranged opposite to the sound wave emitting mechanism and comprises the bionic external ear and the bionic external ear lower flap, the bionic external ear is used for receiving the generated sound waves from the sound wave emitting mechanism, the bionic external ear lower flap is arranged in the bionic external ear and faces the sound wave emitting mechanism, and the bionic external ear lower flap is connected with a first driving mechanism to realize motion and then is partially occluded or not occluded relative to the bionic external ear; and the sound field detection mechanism is arranged at the other side, opposite to the soundwave emitting mechanism, of the simulated external ear mechanism.

Description

technical field [0001] The invention relates to the field of bionic simulation, in particular to a simulated device for imitating a receiving part of a bat and a method for using it. Background technique [0002] After a lot of research, it is found that the outer ear of the big-eared bat has a mechanism to control the beam direction characteristics, which allows the bat to generate a series of random waves within a frequency period of the ultrasonic (from the ultrasonic echo of acoustic emission or other similar) that it can hear. The frequency changes the moving beam without moving its ear, and multiple beams received in a short time allow the animal to generate enough information over a large solid angle. At present, the research on the frequency-sweeping principle of the outer ear of the big-eared bat is still in the mechanism research stage. The inventors found that there is no related device that can complete the simulation of the frequency-sweeping principle of the ou...

Problems solved by technology

At present, the research on the frequency-sweeping principle of the outer ear of the big-eared bat is still in the mechanism research stage. The inventors found that there is no related device that can complete the simulation of the frequency-sweeping principle of the outer ear of the bat. It is helpful for simulation, analysis and research on how to control the beam direction and apply it to bionic sonar antenna, etc.
