Microphone
Product Code : LSK-PL-10296
Microphone (SKU LSK-PL-10296) is a crystal microphone unit in a moulded plastic box, made to feed sound into an oscilloscope so a class can see the waveform of a voice, whistle or tuning fork. It suits sound and waves lessons at secondary and college level. A laboratory equipment manufacturer in India, Science Lab Supplies builds the unit at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and sells it directly to schools, colleges, tender contractors and distributors.
Specifications
Element, housing, connection, impedance and size of the microphone unit are set out one per row. In short, a crystal microphone sits in a moulded plastic box of 55 x 110 x 22 mm, with a 4 mm connection for leads to the oscilloscope input and an impedance of 1 MΩ.

Applications and Experiments for the Microphone
Connected to an oscilloscope, the microphone turns sound into a visible trace. Students can compare loud and soft sounds by amplitude, high and low notes by the spacing of the waves, and a pure tuning-fork note with the more complex shape of a voice, which makes sound lessons concrete.
- Class 9 science: sound as a wave, with pitch and loudness.
- Class 11 physics: comparing the pure note of a Tuning Fork Set with the shape of a voice.
- B.Sc. physics: sound and acoustics demonstrations with an oscilloscope.
- Connecting to the oscilloscope input with Connecting Leads with 4 mm Safety Plugs.
Standard Scope of Supply
The Microphone is supplied as a single unit: the crystal microphone in its moulded plastic box with the 4 mm connection. An oscilloscope and 4 mm leads are needed to display the signal and are separate items that can be listed on the same quotation.
Packing, MOQ and Lead Time
A single microphone covers a teacher’s demonstration, and several can be ordered for group work; each quotation states the packing, delivery time and price for the quantity given. An oscilloscope and leads for the same sound bench can be added to it.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Nigeria, Kenya, Ghana, Ethiopia, Tanzania and Uganda. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). To get the microphone priced on its own or with an oscilloscope, contact the team on the contact page, keep a list in the enquiry cart, or submit tender details on the lab tender page.
Frequently Asked Questions
What is this microphone used for?
It is a microphone unit for use with an oscilloscope, so the waveform of a voice or other sound can be demonstrated on the screen during sound and waves lessons.
How does it connect to an oscilloscope?
The box has a 4 mm connection, so standard 4 mm leads run from the microphone to the oscilloscope input. Its impedance is 1 MΩ, and the crystal element is housed in a moulded plastic box.
Is Science Lab Supplies the manufacturer or a trader?
This microphone unit is made at the Science Lab Supplies factory in Saha, Ambala, India; the company is its manufacturer, and buyers receive their quotation from that factory rather than an agent.
How big is the unit?
The moulded plastic box measures 55 x 110 x 22 mm (length x width x height) and holds the crystal microphone element with its 4 mm connection.
Related Sound and Signal Equipment
A sound practical needs something to display the signal and can also use something to produce or measure sound. These items give two ways to view the microphone’s output, a loudspeaker and two generators for playing tones, a sound level meter and a reflection apparatus, all on one quotation.
- Oscilloscope — 320 x 240 colour display, supplied with probes and a protective case.
- PC Oscilloscope — needs a USB 2.0 port and a 1024 x 768 display on the PC.
