Cicadas make sounds through membrane vibrations, but only male cicadas can make sounds.
The cicada has a thin articulatory membrane under its abdomen, which is divided into two chambers, the large chamber has a fold membrane and a mirror membrane, and the small chamber tympanic membrane is located in the body. When the tympanic membrane muscle of the insect's chamber contracts up to 10,000 times per second, it causes the ventricular hair fold membrane and the mirror membrane to vibrate, resulting in a loud sound.
Cicadas are hemiptera cicadas found in temperate and tropical regions, inhabiting deserts, grasslands, and forests. The larvae of cicadas live in the soil and have a pair of strong digging forefeet that use their stinging mouthparts to suck the sap of plant roots; In late July, female adults begin to lay eggs, and the peak oviposition period is in early and mid-August.

The known cry can be written as squeak. The two small discs on the belly of the male are called the sound cover, and there is a transparent film on the inside of the sound cover, which is called the valve, which is actually the sound made by the valve, and people use a megaphone.
to amplify their voice, the sound cover is equivalent to the cicada's megaphone to expand the sound, it will make a squeaky sound, and the female knows that there is no sound cover and valve on the belly, so the female knows not to scream, and it is also called a dumb cicada.
Got the relevant introduction
In the afterlife and present life of the cicada, the cicada is a phylum of arthropods.
Insecta, Hemiptera.
A class of organisms in the family Cicadas. There are about 3,000 species known.
The life of a cicada goes through three stages: fertilized egg, larvae, and adult. In the summer, fertilized eggs laid in the early years hatch into larvae, which burrow into the soil and feed on the sap of plant rhizomes.
When the larvae mature, they crawl to the ground and shed their golden exoskeleton.
Feathering is our common adult with wings. Although adult cicadas only live for a few months, the larval stage can survive in the soil for many years, such as the larval stage of a cicada with a 6-year lifespan, which accounts for 5 years of its life.

Yes"Got it-got it-got it"to describe, belongOnomatopoeia。Or with "chirp", "squeak", etc.
There are more than 3,000 species of cicadas in the world.
In our country, the land is vast, and there are cicadas singing all year round.
In spring, there are "spring cicadas", which shout "wake up, wake up" when they chirp; In summer, there are "summer cicadas", which shout "hot death - hot death" and "know - know it" when they chirp; In autumn, there are "autumn cicadas, which shout "obey - obey" when they chirp; In winter, there are "winter cicadas" that chirp and shout "it's over—it's over".
1. Knowing the characteristics: cicadas are usually five or six centimeters long, with three less sensitive eyespots between their eyes, and the two wings are simply distributed with supporting thin tubes, like a hollow mouth in the needle that can pierce into the tree to suck the sap. The male cicada has a high-pitched voice on the abdomen, while the female does not make a sound but has a hearing device on the abdomen.
2. Knowing the characteristics of life: the larvae live in the soil, and when they are about to feather, they will burrow on the surface of the soil at dusk or at night and molt and feather, and in summer they will cry loudly in the trees and suck the sap with a needle mouthpiece.
Distribution: Distributed in temperate and tropical regions.
Inhabits deserts, grasslands, and forests. Except every year in the middle of summer.
In addition to the species of the genus Mothcia, there are also periodic cicadas. The most famous periodic cicada is the seventeen-year cicada.
and the thirteen-year-old cicada, also known as prime numbers.
Cicadas, because their life cycle is a prime number, will not encounter the natural predators encountered in the previous generation. Periodically, cicadas occur once in a certain area at certain intervals, when dozens to hundreds of black-brown cicada larvae emerge from the soil and emerge together, which is very spectacular. Some species are easier to identify by their vocalization, behavior, and morphology.

It is known that the muscles are used to make the eardrum vibrateThe cicada is a male cicada, its articulator is at the base of the abdomen, like a large drum covered with a layer of tympanic membrane, the eardrum is vibrated and makes sound, because the vocal muscle can be expanded and contracted about 10,000 times per second, the cover plate and the eardrum are empty, and can play a resonant role, so its song is particularly loud. The male cicadas of each species make three different calls: the aggregation sound; courtship sounds before mating; The gruff sound of being caught or frightened and flying away.
The female cicada's instrument is not fully constructed, so it is a "dumb cicada".
The female cicada has no sound "equipment" on her body and is a veritable mute.
After mating, it climbs onto the branches of willow or mulberry trees, pierces the tender cortex with its jagged oviposition, lays its eggs in it, and thorns it until it lays its eggs. Therefore, cicadas are a garden pest. On each side of the anterior abdomen of the male cicada, there is a large, round sound cap, and underneath it has an auditory capsule and a vocal membrane like a drum skin.
The male cicada's call is a signal to find the opposite sex, and the female cicada will hear the call and fly close to her to mate her tail and reproduce her offspring.

I know that the sound is made through the voice organ in the abdomen.
It is known that sound is produced through special organs, the main organ of which is the voice organ located in the abdomen. This vocal apparatus consists of two hardened structures (called sonorine plates) that produce sound through the contraction and relaxation of muscles. Knowing that the process of making sound is similar to playing a musical instrument, the male knows that by vibrating the voice caller, the internal pressure change is converted into sound waves, and the sound is humming.
The structure and vibration of the voice resonator may vary slightly from one type of voice to another, so the sound of their chirping is also different. It is worth mentioning that the loudness of chirps is very similar to noisy, because they have special vocal apparatus and ligaments that can produce strong sound waves.
I know the purpose of the tweet
1. Attracting mates: Males know how to attract females through chirping, and each species' chirping has a unique frequency, rhythm and rhyme, which makes females know that they can identify and choose a suitable mate through their voices.
2. Field declaration and guessing: Knowing that the chirp is also used to declare its territory or field, the male will use loud, loud and continuous chirps to warn other males not to enter its territory.
3. Communication and communication: Knowing each other can also communicate through the sound of chirps, which can express warning, attract partners, and transmit danger signals and other information through the sound of chirps.

The scientific name is cicada, and not all cicadas can call, only male cicadas can call. There is a pair of articulators at the front end of the abdomen of the male cicada, and the outside of the articulator is a pair of semicircular covers, and there is an elastic film in the cover, called the "tympanic membrane", the eardrum is connected to the vocal muscle, and the eardrum will make sound when it is vibrate, and the sound resonates in the space under the cover, so the sound is very loud.
Cicada chirping is meaningful, because the cicada's eyesight is very poor, and it is very difficult for it to find the opposite sex nearby, so cicada chirping is actually a way for male cicadas to attract female cicadas.
There is a record of cicada eating in the ancient "Book of Rites", when cicadas were not only the food of ordinary people, but also became a delicacy at the banquet of kings and nobles, and the custom of eating cicadas was retained in many places.
Cicadas are eaten in a variety of ways and can be roasted, fried, and fried. It is the same as earthworms, grasshoppers, ants, bean insects, silkworm pupa, scorpions, bee pupae and other Kunbei simple insects, which are high-protein food.

The principle of violin pronunciation is transmitted to the sound column in the case through the steel strings on the piano case, causing resonance, and the sound quality of the pronunciation depends entirely on the manual craftsmanship of the piano case and the selected materials. Generally, violins are made of maple wood, because maple wood is a smooth fiber, and the sound transmission speed reaches about 5000 meters per second, so it is necessary to choose good maple wood to make violins, which is the premise of ensuring sound quality. Secondly, it is the selection of bow hair, generally choose the horsetail hair of the white horse with better hair quality, the same smooth fiber, after coating the rosin to increase the friction, so the violin naturally emits some original sound. >>>More

If there is such a sound in the mobile phone, I think it is very likely that your mobile phone is not particularly strong, because before my mobile phone was repaired, its mobile phone battery was originally sticky, so it was removed and disassembled, and now it is reinstalled, because the sticky is not good, and there is a collision, it can hear the sound of the mobile phone battery shaking when the mobile phone shakes.
There is a sound-producing structure in the human neck called the larynx. It has a cavity inside it, which we call the laryngeal cavity, and in the middle of the laryngeal cavity are connected to two muscles that vibrate and produce sounds—the vocal cords. They sit side by side tightly, and like rubber bands, the tighter you pull, the louder your ** becomes. >>>More
