Abstract

The invention provides a string vibration period experiment instrument with a vibration motor and an electric vibration tuning fork as double vibration wave sources. The string vibration period experiment instrument with the vibration motor and the electric vibration tuning fork as the double vibration wave sources aims to the solve the technical problems that an existing string vibration experiment instrument is complicated in equipment structure, a dead zone exists during an experiment, and the demonstration effect is poor. The string vibration period experiment instrument comprises an experiment instrument body. A base is arranged at the bottom of the experiment instrument body, and a vibration motor assembly is installed on the experiment instrument body. The vibration motor assembly is installed on the head portion of the electric vibration tuning fork through a fixing flat plate. The vibration motor is installed in the vibration motor assembly. An eccentric block is installed on the right side of an outer rotating shaft of the vibration motor. A direct-current power source frequency measurement instrument is installed on the left side of the base. A voltage adjusting and frequency adjusting power source and a vibration motor frequency measurement instrument are installed on the direct-current power source frequency measurement instrument. The voltage adjusting and frequency adjusting power source is provided with a voltage adjustment and frequency adjustment alternation switch, a power switch and the like. The vibration motor frequency measurement instrument is provided with a power supply switch, a frequency switch and the like. When the string vibration period experiment instrument is used, through the steps of power source connection, voltage adjustment and the like, the string vibration frequency is obtained by measuring the vibration frequency with the vibration motor as the wave source finally. The double vibration wave sources can be mutually checked and compared. The string vibration period experiment instrument with the vibration motor and the electric vibration tuning fork as the double vibration wave sources has the advantages that the structure is reasonable, an operation method is easy to implement, and the demonstration effect is remarkable.

Description

Technical field [0001] The invention relates to a string vibration experiment instrument, in particular to a string vibration period experiment instrument with a vibration motor as a wave source. The string vibration tester is mainly used in university physics experiments, and belongs to the field of mechanical and thermal physics experiments. Background technique [0002] At present, in the field of mechanical and thermal physics string vibration experiments, the following vibration methods of string vibration wave sources are generally used: the string vibration method with electric vibrating tuning fork as the wave source or the string vibration method with electromagnetic vibrator as the wave source. There are many disadvantages in the above methods. Although the first method has obvious demonstration effects and low cost, it has serious experimental blind spots and low experimental efficiency. The latter kind of demonstration effect is not obvious, and the equipment structu...
