In a standard non-electronic telephone the transmitter is wired between the two incoming wires of the telephone line. A 'carbon granule' transmitter consists of a small tube filled with carbon granules with a piston at one end attached to a diaphragm. Sound waves cause the diaphragm to vibrate and compacts or loosens the granules altering their electrical resistance in sympathy with the sound. This modulates the line current and is received at the telephone exchange via a transformer called a 'transmission bridge'.

∙ 13y agoThe tranducer/microphone converts the vibrations of the waves into electrical audio signals, the vibrations cause a diaphragm inside the transducer to vibrate which in turns create pulses of current that can be interpreted later as the recorded audio.

What is The part of a sound wave that you hear as loudness?
Amplitude. As the amplitude of the sound wave increases, the sound becomes louder.
Which part of sound wave has molecules that are not tightly packed together?
rarefraction
Compression happens during which part of the sound wave?
it happens during the trough
Which part of sound wave has molecules that are tightly packed together?
it is called the compression
Sound travels in what kind of wave?
Sound is a longitudinal, mechanical wave that requires a medium.
Why isn't sound a part of the em spectrum?
Sound is a mechanical wave, not an electromagnetic wave.
What part of the electromagnetic spectrum does the ultrasonic wave falls into?
An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.
What is receiver capsule?
receiver capsule is a telephone device who can detect sound wave
What is The part of a sound wave that you hear as loudness?
Amplitude. As the amplitude of the sound wave increases, the sound becomes louder.
What are energy transformation in a telephone?
The telephone system converts acoustic energy into electric energy
The higher pressure part of a sound wave is called?
Shock waves
What wave is not part of the electromagnetic spectrum?
Sound wave, waves on the surface of water, earthquake waves
How does a sound wave move through molecules?
Sound wave travels from one part in to another part in air due to change in density of molecules from one point to another point
How does rarefraction affect sound?
Rarefaction is the part of the sound wave where the air particles are the farthest apart from each other. It's like the "trough" of a transverse wave. The size of this part affects the wavelength and amplitude of the sound produced, which changes the volume and pitch. Note that there's also another part of the wave called "compression". This is like the "peak" of a transverse wave.
Is a sound wave a transverse wave?
No, a sound wave is a compressional wave.
Are infrared waves sound waves?
No; sound is a mechanical wave, infrared is a part of the electromagnetic spectrum.
Is a sound wave part of a electromagnetic spectrum?
No, a sound wave is not electromagnetic, it is a pressure wave in the air. The speed of propagation is about 1100 ft/second, so 1 mile in 5 seconds.
