Abstract

The invention relates to an experimental box for transmitting sound; the experimental box disclosed by the invention is a teaching tool which generates and transmits the sound by utilizing a tuning fork, a small mallet, inspection material which shares a joint with the tuning fork, and a resonance box which is served as a package box in the meanwhile. The experimental box disclosed by the invention is characterized by convenient use and cheap price; students feel sound transmission in water, iron, glasses and sticks only in a method of adding some inspection material such as sticks, glass rods, iron rods and the like, a flask and a water groove; therefore, the experimental box is not only used for an experiment of a student team, but also used for an individual experiment.

Description

The propagation experimentation box of sound

Technical field

Patent of the present invention relates to is that hold concurrently packing case, beaker etc. of a kind of experimental material, resonant tank with tuning fork, gavel and tuning fork shared interface are combined into, and carries out the teaching aid of the generation and the propagation of sound.Available teaching or extracurricular activities that it comes demonstrating sound in solid and liquid, also can propagate.

Background technology

In the teaching of carrying out acoustic propagation, be mostly that tuning fork and resonant tank are combined into a cover teaching aid.Also do not have at present a kind of teaching aid can the experiment that solid, liquid also can transmit sound well be illustrated in the student in face of.

Summary of the invention

In order to solve defective of the prior art, design this device, technical scheme is following:

1; Between traditional tuning fork and resonant tank, add the experimental material of processing with the unlike material of the shared interface of tuning fork, the shape size is identical.

2; On resonant tank, install the tank of a dress water additional.

The propagation experimentation box of sound is combined into by tuning fork, resonant tank, gavel, experimental material, beaker etc.; Being used for sound is the teaching aid that how to produce and propagate, it is characterized in that being equipped with the tuning fork shared interface, shape size experimental material identical, that unlike material is processed and beaker, tank.

This experiment box easy to use, low price only just can let the student all experience the propagation of sound in water and iron, glass, wooden stick at experimental materials such as increasing beaker, wooden stick that tank is identical with some shapes size, glass bar, iron staff in the general tuning fork experiment box.

Embodiment

In the experiment box of tuning fork except tuning fork and gavel, add upper flume with can be shared with the interface of tuning fork, that unlike material is processed, experimental material (like batten, bonding jumper, plastic strip etc.) that the shape size is identical, assemble by demand again during use and get final product.As to check glass bar can transmit sound, just insert glass bar the interface of original resonant tank and tuning fork, hit tuning fork with gavel again after, contact tuning fork with glass bar just and can accomplish experiment.

Claims

1. the propagation experimentation box of sound is combined into by tuning fork, resonant tank, gavel, experimental material, beaker etc.; Being used for sound is the teaching aid that how to produce and propagate, it is characterized in that being equipped with the tuning fork shared interface, shape size experimental material identical, that unlike material is processed and beaker, tank.
