How do cicadas make sounds, and how do cicadas make sounds

The cicada's articulator is at the base of the abdomen, like a large drum covered with a layer of eardrum, and the eardrum is vibrated to make sounds.

Because the vocal muscles can expand and contract about 10,000 times per second, and the gap between the cover plate and the eardrum is empty, which can play a resonant role, its sound is particularly loud. It can take turns to use a variety of different tones to sing passionately, and the female cicada's musical instrument structure is incomplete and cannot make a sound, so it is a "dumb cicada", and the female cicada does not have a vocalizer, so it becomes a "dumb cicada."

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. When the muscles in the lining of the membrane contract and vibrate, the cicada makes a sound.

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 land areas, inhabiting deserts, grasslands and forests. The larvae of cicadas live in the soil and have a pair of strong, shape-like digging forefeet that use their stinging mouthparts to suck the sap of plant roots; In late July, the female adults began to lay eggs, and the early and mid-August months were the peak ovipositions.

The cicada is a male cicada, and its articulator is on the abdomen, like a large drum covered with a layer of eardrum, and the eardrum is vibrated to make sounds.

Sound, because the sound muscle can be retracted about 10,000 times per second, the cover plate and the tympanic membrane are empty, can play a resonant role, so its sound.

Particularly loud. And can take turns to sing passionately in a variety of different tones.

The cicadas drank the clear dew with their heads down and cries from the tall plane trees.

It is located in a high place, and the sound can naturally travel far away, not with the help of the autumn wind.

2."Cicada" is a five-character ancient poem written by the Tang Dynasty poet Yu Shinan, which is a poem with the meaning of things. Original:

Drink the dew, and the sound of dredging is out.

Raising his voice from afar, not by the autumn wind.

3.Notes:

淌 (ruí): The ancient official hat is knotted and drooping, and the head of the cicada has tentacles that stretch out, and the shape is like a drooping crown tassel. It also refers to the thin beak on the chin of the cicada, which resembles a hat band.

Dew: Pure dew. Drinking dew: The ancients believed that cicadas were noble in nature and drank dew when they dwelled high, but they actually sucked the sap of plants.

Stream: Emitted. Flowing sound: refers to the cicada singing endlessly, and the sound travels far away.

Tung tree: Tall sycamore.

Contiguous: refers to perching on a high place, pun intended.

藉 (jiè): to rely on, to rely on.

The implication is that the gentleman should be as high and distant as the cicada, and do not have to rely on or be subject to other things. It expresses the poet's enthusiastic praise and high self-confidence for people's inner character, and shows a graceful and unhurried demeanor.
