What is the sounding body that strikes the glass

The column of air vibrates and makes a sound. But then I saw that some books said: In fact, it is mainly the vibration of the glass, because the bottom of the cup is filled with water and water as a whole, when the lower part of the vibration is very small, it is thought that it will no longer vibrate, only the upper part is vibrating, so the more water is filled, the shorter the vibration part of the cup, the greater the frequency, and the higher the tone.

If you think about it carefully, in fact, whether it is a cup or a column of air or water when you knock on it, it just depends on who is in the main position, so both statements are correct, but I still agree with the second statement because I don't think that much sound can be made by tapping the air column alone.

A sound emitter is an object that is capable of producing sound on its own. The vocal parts of different vocal bodies are generally different.

Sound is produced by the vibration of an object. Everything that makes a sound vibrates. (Note: Unlike a sound source, which is an object that is emitting sound, a sound emitter is an object that is capable of emitting a sound).

For example: the vibrating vocal cords, the vibrating tuning fork.

Drums and other sounds are sounding bodies.

Generally, this problem will be interpreted by the teacher as the vibration of the air column and the sound.

But then I saw that some books said: In fact, it is mainly the vibration of the glass, because the bottom of the cup is filled with water and water as a whole, when the lower part of the vibration is very small, it is thought that it will no longer vibrate, only the upper part is vibrating, so the more water is filled, the shorter the vibration part of the cup, the greater the frequency, and the higher the tone.

Let's think about it carefully, in fact, whether it is a cup or a column of air or water when you knock on it, it just depends on who is in the main position, so both statements are correct, but I personally agree with the second statement because I think that the sound of hitting the air column alone is not so loud.

You can often see footage of music playing in a glass, and the sound is very beautiful. It is possible with a normal glass, too. A glass like a goblet has a loud echo, and when you flick the rim with your finger, it makes a beautiful sound, and sometimes it echoes very loudly in the room.

This is because when you flick the glass with your finger, the edge of the cup vibrates, and this vibration is combined with the vibration (called natural vibration) that the glass is prone to produce in the first place, and the vibration becomes louder and louder, and the sound is generated. At this time, if you pour half a glass of water into the glass, you can see that the vibrations make the water surface ripple. In order to successfully carry out this test, it is necessary to wash both the glass and your fingers, as impurities such as oil stains can affect the sound.

It should be noted that when the double-layer glass vibrates and makes a sound, it is necessary to prevent it from bursting, and the reason for the explosion is because as soon as hot water is poured into the expansion cup, the inner wall of the cup is heated and expands sharply, but the outer wall of the cup remains the same, and the inner glass is suddenly squeezed outward, and the cup is broken.

When the vibrations (called natural vibrations) that are easy to produce are combined, the vibrations become louder and louder, and sound is generated. At this time, if you pour half a glass of water into the glass, you can see that the vibrations make the water surface ripple. In order to successfully carry out this test, it is necessary to wash both the glass and your fingers, as impurities such as oil stains can affect the sound.

The length of the air column in the cup is different when the water is different, and when the same size of blowing force is used, the resonance effect is different, and the tone obtained is different.

When you flick the glass with your finger, the edge of the cup vibrates, and this vibration is combined with the vibration (called natural vibration) that the glass is prone to generating, and the vibration becomes louder and louder, so the sound is generated. At this time, if you pour half a glass of water into the glass, you can see that the vibrations make the water surface ripple.

Like normal musical instruments, the sound is caused by vibration, and the glass performance uses the air column to vibrate, and different glass depths are different, and the air column is different, which also has different tones.

When you knock on the rim of the glass, it vibrates, so it makes a beautiful sound, and it makes different sounds depending on the vibration.

Because if you hit the edge of the glass, the edge will vibrate, and then there will be a sound, which is relatively normal.

This is because the glass will make a crisp sound when it collides with something of a specific material, so it will make a beautiful sound.

This is because: knocking on the cup filled with water makes a sound because the sound at this time is due to the vibration of the cup and water, when knocking on a cup with a lot of water, because the more water, the smaller the vibration frequency of the air column formed in the cup, so the sound is low and deep.

When you hit a cup with less water, the frequency of the air column is very small because there is less water and the air column is long, and the sound produced by the water and the cup is relatively clear.

That's some of the sound effects stored in the ** software, recorded in advance in the recording studio. Not a real instrument.

I think it's a celesta or a xylophone, these two are more in line with your description, and the sound is crisp.
