Loud Speaker
Product Code : JL-LEP-10427
The Loud Speaker (SKU JL-LEP-10427) is a 2-inch, 1 W, 4–8 ohm loudspeaker on an open board and stand, used with a tone generator to provide a continuous sound of a set frequency. The centre of this loud speaker sits 52 mm above the table so that it lines up with the mouth of the resonance tube, making it the sound source for resonance and wavelength experiments. JaincoLab manufactures it in India for school and college physics.
Specifications
The loudspeaker has a 2-inch cone rated at 1 W (all-frequency or low range) with 4 to 8 ohm impedance, has no enclosure, and is mounted on an open board and stand with its centre 52 mm above the table to match a resonance tube.

Applications of the loud speaker
Driven by a tone generator, the speaker sends a steady tone into the resonance tube while the air column is adjusted, so students can find resonance lengths and calculate the wavelength and speed of sound.
- Sound source for resonance tube experiments with a tone generator
- Finding resonance lengths of an air column at several frequencies
- Calculating the wavelength and speed of sound in air
- Demonstrating how pitch changes with frequency across the audible range
- Sound and waves practicals in secondary and college physics
