Embodiment Construction

[0008] refer to figure 1 , the human ear dynamic demonstration model is to use a thin plastic bowl 1 as the pinna to collect sound waves; cut out a round hole at the bottom of the thin plastic bowl 1, and place it Cover a layer of plastic film 2 as the tympanic membrane of the simulated ear, and the tympanic membrane has the effect of causing vibration;

[0009] Use a plastic tube 3 as the external auditory canal and connect it to the round hole cut out by the thin plastic bowl 1. The external auditory canal has the function of transmitting sound waves; then this device is fixed on a photo picture printed with the structure of the ear and the human brain to show the simulation Live;

[0010] Connect a pin 5 on the plastic pipe 3, connect a wire 4 on the pin 5, the other end of the wire 4 is connected with the center of the plastic film 2 covered on the bowl mouth of the thin plastic bowl body 1, the pin 5 is connected with the wire 4 The simulated auditory ossicles can trans...

Abstract

A dynamic demonstration model for sound being received by a human ear relates to a teaching aid, which is characterized in that a thin plastic bowl is used as an auricle; a plastic film is covered on the top of the bowl to serve as the tympanic membrane of the simulated ear; a plastic tube is connected to the circular hole in the bottom of the plastic bowl; a pin connected on the plastic tube is connecting with a lead; the other end of the lead is connected with the center part of the plastic film covered on the top of the bowl; and a screw is provided on the contact point between the LED lead and the pin. The experiment of simulating sound being received by a human ear can be carried out by adjusting the distance between the screw and the pin and clapping toward the top of the bowl until the LED gives off light. The dynamic demonstration model allows students analyzing the transmission process of sound; gradually understanding the function of every part of an ear, thereby significantly arousing students' enthusiasm for learning and leaving deep learning impression.

Description

technical field [0001] The invention relates to a teaching aid. Background technique [0002] Among the existing teaching aids, there is no teaching aid that can directly, vividly and dynamically demonstrate the process of human hearing. The existing human ear models can only allow students to understand its structure, but cannot demonstrate the process of sound transmission. Contents of the invention [0003] The purpose of the present invention is to provide a dynamic demonstration model of human ear hearing. This dynamic demonstration model of human ear hearing is to use a thin plastic bowl, cut out a round hole at the bottom of the thin plastic bowl, and cut out a hole in the thin plastic bowl. The mouth of the bowl is covered with a layer of plastic film as the tympanic membrane of the simulated ear; a plastic tube is connected to the round hole cut out of the thin plastic bowl, the thin plastic bowl is used as the auricle, and the plastic tube is used as the externa...
