Embodiment 1

[0028] A device for simulating the sound characteristics of a chrysanthemum chrysanthemum bat, comprising a nose bionic mechanism, a sound wave emission mechanism and a controller 6, the nose bionic mechanism and the sound wave emission mechanism are fixed on the base 1, and the controller 6 is electrically connected to the sound wave generating mechanism; The internal bionic mechanism includes a saddle-shaped leaf 4, the distance between the saddle-shaped leaf 4 and the sound wave emitting mechanism can be changed, the controller 6 controls the sound wave generating mechanism to emit sound waves, and the sound waves can reach the saddle-shaped leaf 4. The principle of the present invention essentially simulates the physiological structure of the horseshoe bat, and then explores the vocal characteristics of the horseshoe bat. For the horseshoe bat, the principle of its sound is still consistent with that of mammals. The sound is made through the vocal cords in the throat, and t...

Embodiment 2

[0040] Embodiment 2 discloses a method for simulating the sound characteristics of the horseshoe bat, comprising the following steps:

[0041] Turn on the sound wave emission mechanism;

[0042] The controller 6 controls the movement of the electric push rod 2, and the sound wave detection device detects the physical properties of the sound wave.

[0043] In this implementation, the acoustic wave detection device uses the device and method disclosed in the publication number CN106409109A.

[0044] In this embodiment, the controller 6 controls the electric push rod 2 to move multiple times in units of 1mm, and the width, amplitude and repetition frequency of the sound wave are detected by the sound wave detection device for each movement, and recorded,

Abstract

The invention discloses a chrysanthemum chrysanthemum bat sound characteristic simulation device, which comprises a nose bionic mechanism, a sound wave emitting mechanism and a controller, the nose bionic mechanism and the sound wave emitting mechanism are fixed on a base, and the controller is electrically connected to the sound wave generating mechanism; The nose bionic mechanism includes a saddle-shaped leaf part and a telescopic part, and the telescopic part is connected to the saddle-shaped leaf part; the controller controls the sound wave generating mechanism to emit sound waves, and the sound waves can reach the saddle-shaped leaf part. The nose bionic mechanism disclosed by the present invention can simulate the physiological structure of the chrysanthemum chrysanthemum, and at the same time cooperate with the operation of the sound wave emission mechanism, can change the characteristics of the sound wave emitted by the sound wave emission mechanism, and realize further improvement in the sound wave emission of the chrysanthemum chrysanthemum. study in depth.

Description

technical field [0001] The invention relates to the field of bionics, in particular to a device and method for simulating the sound characteristics of a chrysanthemum bat. Background technique [0002] The nose is an important organ of the organism, it is the initial part of the respiratory passage, and it is also an olfactory organ. It consists of three parts: the external nose, nasal cavity and paranasal sinuses, and is composed of nasal bone, nasal cartilage, nasal muscles and covering skin. The nasal cavity is divided into left and right chambers by the nasal septum. The nostrils communicate with the outside world at the front, and the nasopharynx at the rear. In the biosonar system, bats use the complex fold structure on the nasal lobes to adjust the ultrasonic pulses emitted from the nostrils to obtain adjustable beamforming. The high saddle horseshoe bat was discovered by biologist Bourtct in the tropical rainforest of Vietnam in 1951. At that time, he was surprised...
