Kunds Tube with Microphone & Speaker Manufacturer,Supplier and Exporter in India

Product Code : SCL-PLE-11902

The Kunds Tube with Microphone & Speaker by Scientifc Equipment is an educational physics laboratory apparatus designed to demonstrate sound waves, resonance, standing waves, nodes, antinodes, wavelength, frequency, amplitude, and the speed of sound in air. It is suitable for school physics laboratories, college science labs, STEM classrooms, acoustics lessons, teacher demonstrations, and supervised student practical experiments.

This apparatus helps students observe and measure how sound waves behave inside a tube. The speaker produces sound waves, while the microphone detects sound intensity at different points, allowing students to study resonance patterns, standing wave formation, and acoustic behaviour in a controlled laboratory setup.

Product Description

Kunds Tube is commonly used in acoustics experiments to investigate sound propagation and standing wave formation. When sound of suitable frequency is produced inside the tube, waves reflect and interfere to form stationary wave patterns. The microphone can be used to detect variations in sound intensity along the tube, helping locate nodes and antinodes.

The Scientifc Equipment Kunds Tube with Microphone & Speaker may include a transparent tube, speaker unit, microphone probe, movable carriage, scale, tube supports, connecting leads, signal input terminal, base, and activity guide depending on product configuration. It is designed for supervised educational and laboratory demonstration use only.

How to Use

1. Place the Kunds Tube with Microphone & Speaker on a stable, clean, dry, and level laboratory bench.
2. Inspect the tube, speaker, microphone, supports, scale, leads, and signal terminals before use.
3. Connect the speaker to a suitable low-voltage audio signal generator or approved signal source.
4. Connect the microphone to a suitable display device such as an oscilloscope, data logger, amplifier, or meter depending on setup.
5. Keep the volume and signal level low before switching on the equipment.
6. Set a selected frequency on the signal generator and allow the speaker to produce sound inside the tube.
7. Move the microphone slowly along the tube to detect changes in sound intensity.
8. Identify positions where the signal is maximum and minimum, representing antinodes and nodes.
9. Measure the distance between successive nodes or antinodes to estimate wavelength.
10. Use the measured wavelength and frequency to calculate the speed of sound if required.
11. Repeat the experiment at different frequencies and compare the results.
12. Switch off the signal source before changing connections or handling the speaker and microphone.
13. After the experiment, disconnect all leads and store the apparatus safely.

Safety and Handling Instructions

• Use only under teacher, laboratory instructor, or trained adult supervision.
• Use only the recommended low-voltage signal source and do not connect directly to mains electricity.
• Keep sound volume at a safe classroom level; do not place ears close to the speaker or tube opening.
• Do not operate at very loud volume or uncomfortable frequencies for long periods.
• Switch off the signal generator before changing speaker, microphone, or lead connections.
• Handle the tube carefully, especially if it is glass or transparent acrylic.
• Do not insert sharp objects, liquids, powders, or unsuitable materials into the tube unless approved by the experiment guide.
• Keep the apparatus away from water, wet benches, chemical spills, flames, and damp storage areas.
• Do not use cracked tubes, damaged speakers, faulty microphones, exposed wires, loose terminals, or unstable supports.
• Store the microphone and speaker leads neatly to prevent tangling or damage.
• Store the apparatus in a clean, dry, and protective place after use.

Educational Applications
