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

Abstract

The invention relates to an animal external ear sound characteristic simulator. The animal external ear sound characteristic simulator comprises a signal transmitter, an external ear movement device and a control device, wherein the signal transmitter is used for generating a sound wave signal; the external ear movement device comprises a first traction mechanism, a second traction mechanism and a simulated external ear facing the signal transmitter; the simulated external ear is used for receiving sound waves from the signal transmitter; the first traction mechanism is connected with the ear tip of the simulated external ear and is used for controlling the ear tip of the external ear to move; the second traction mechanism is connected with the middle part of the simulated external ear and is used for controlling the middle part of the external ear to move; a sound wave detector is installed at the root part of the simulated external ear, and is used for measuring sound wave frequencies received by the simulated external ear; and the control device comprises a first traction controller, a second traction controller and a 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...
