DC String Vibrator Manufacturer,Supplier and Exporter in India
Product Code : JL-LEP-10406
The DC String Vibrator (SKU JL-LEP-10406) is a motor-driven string vibrator used to demonstrate standing waves on a string. An offset-weighted shaft on a 0–6 V DC motor shakes the string, and a stepless attenuator adjusts the vibration frequency until clear nodes and antinodes form. It is mounted on a steel platform with binding posts and comes with 5 m of 3 mm polyester-cotton string. JaincoLab manufactures it in India.
Specifications
The string vibrator uses an offset-weighted shaft on a DC motor running from 0 to 6 V, with stepless frequency control through an attenuator, a steel mounting platform with binding posts for the supply wires, and 5 m of 3 mm (size #72) twisted polyester-cotton string.

Applications of the string vibrator
One end of the string is tied to the vibrator and the other passed over a pulley or fixed point; adjusting the frequency or tension produces standing waves with one, two or more loops that students can count and measure.
- Producing standing waves and identifying nodes and antinodes
- Relating the number of loops to vibration frequency and string tension
- Measuring wavelength between nodes to find wave speed
- Linking standing waves on strings to musical instruments
- Waves practicals in secondary and senior secondary physics
