Animal Outer Ear Sound Characteristic Simulator

Abstract

The invention relates to an animal external ear sound characteristic simulator comprising a signal transmitter, an external ear movement device and a control device; the signal transmitter is used to generate a sound wave signal; the external ear movement device includes a first traction mechanism, a second traction mechanism and the The simulated outer ear placed relatively to the signal transmitter; the simulated outer ear is used to receive sound waves from the signal transmitter; the first traction mechanism is connected to the ear tip of the simulated external ear, and is used to control the movement of the external ear tip; the second traction mechanism is connected to the simulated external ear The middle part of the connection is used to control the movement of the middle part of the simulated external ear; a sound wave detector is installed at the root of the simulated external ear to measure the frequency of sound waves received by the simulated external ear; the control device includes a first traction controller, a second traction controller and modulation controller.

Description

technical field [0001] The invention relates to an animal external ear sound characteristic simulator. Background technique [0002] The ear is an important organ of the living body and consists of the outer ear, middle ear, and inner ear. The outer ear includes the pinna, external auditory canal, and tympanic membrane. The shape of the auricle is conducive to the accumulation of sound wave energy, the collection of sound, and the position of the sound source can be judged; the external auditory canal is the channel for sound wave transmission, one end opens at the center of the auricle, and the other end ends at the tympanic membrane, and it is also an effective resonance cavity. It can strengthen the weaker sound wave vibration and cause the eardrum to vibrate. Bats are the only mammals that can truly fly, and have structures in their outer ears for ultrasonic positioning. Bats distinguish objects by emitting ultrasonic waves, and the outer ear receives the echoes refle...

Problems solved by technology

At present, the research on the reception of sound waves by the animal outer ear is still in the mechanism research stage, and the artificial outer ear receiving device is also very imperfect, which cannot achieve the sound wave reception effect of the animal outer ear pair. Therefore, corresponding devices are urgently needed to complete the simulation of receiving sound waves. Simulation, Analysis and Research of Animal External Ear Reception by Movement
