How can so many different sounds be coming from the needle and the record when you spin it?

The pattern of the wavy structure varies along a groove and between grooves. The needle moves back and forth as it moves across the grooves. The structure of the groves causes a push on the needle in different directions as the record spins.

How does sound come from a vinyl record?

Vinyl record players are electromagnetic devices that change sound vibrations into electrical signals. When a record spins, it creates sound vibrations that get converted into electrical signals. Electric amps vibrate and feed the resulting sound into speakers, which amplify it and make it louder.

How do speakers output multiple frequencies at once?

The way that sound works is you can superimpose the motion of the speaker – meaning lots and lots of different vibrations – and that will produce sounds of lots and lots of different frequencies all at the same time, by just making the right pattern for the speaker to move back and forwards.

How do speakers replicate voices?

In speakers, a current is sent through the voice coil which produces an electric field that interacts with the magnetic field of the permanent magnet attached to the speaker. Like charges repel each other and different charges attract. This makes the cone that the voice coil is attached to move back and forth.

How does the sound coming from one thing like the speaker make another thing far away like the window move?

We figure out these concepts: A speaker making sounds can be detected from a distance and can even cause things like a nearby window to move. The speaker moves back and forth when it is making sound. All objects move back and forth (vibrate) when making sounds.

Why do different things make different sounds?

When the particles of object are disturbed then due to vibration,the sound is produced of different frequencies. The combination of different frequency produces the special sound. When the different objects drop on floor then each object vibrate at its natural frequency and produce different sound.

How does vinyl sound different?

To be sure, the sound of vinyl carries additional warmth when recorded through analog rather than digital technology. Richness refers to the diversity of auditory aspects heard in vinyl records. Because of record grooves, the sound of vinyl is more open, allowing a greater quantity of features to be heard.

How does a speaker generate sound?

The center of the speaker cone is attached to one end, which gets driven back and forth by the moving coil. As the cone moves, it pushes and pulls the surrounding air; by doing so it creates pressure waves in the air, called sound.

How many things vibrate when sound is created?

Three things vibrate when sound is created: 1 the source object 2 the molecules in the air (or another medium e.g. water) 3 the eardrum

Why does my record need needle sound strange?

Needle replacement is not always the solution. Note that strange sounds could be caused by extraneous factors, such as: Dust, dirt, and grime easily collect on vinyl. Fingerprints, too, will lessen the quality of the record’s output. It is not uncommon for dust to get lodged on the needle itself.

What is the frequency of a sound?

When we hear something, we are sensing the vibrations in the air. The number of vibrations per second is known as the frequency, measured in Hertz (1 Hz = 1 vibration per second). These vibrations enter the outer ear and cause the eardrum to vibrate too.

How many students do you need to make a sound experiment?

Invite 5 or 6 students to the front of the class to be your volunteers. 1 student is the sound source (holding something that makes a sound, such as a bell). 1 student is the eardrum (holding the drum). 4 students are air molecules between the source and the eardrum.
