Explicação 振動 in your Level:
At the A1 level, you should think of 振動 (shindō) as the word for when your phone 'buzzes.' Even though it is a technical word, it is very useful for basic technology. You don't need to know the physics yet. Just remember: 'Smartphone + buzz = shindō.' You can use it in simple sentences like 'Kētai no shindō' (Phone's vibration). It's a 'noun,' which means it's a thing. If you want to say 'It is vibrating,' you say 'Shindō shite imasu.' This is helpful if you are in a meeting and your phone starts making noise on the table. You can point to it and say the word. It's also useful for describing a car or a bus that is shaking a little bit. Don't worry about the kanji yet; just focus on the sound 'shindō' and the idea of a fast, small shaking motion like a bee's wings or a phone's motor. This level is about survival and basic identification of objects and their states.
At the A2 level, you can start using 振動 (shindō) to describe your environment. You might use it to talk about construction work near your house or a noisy appliance. You should be able to distinguish it from 'yureru' (to sway). For example, you can say 'Kōji no shindō ga urusai desu' (The construction vibration is noisy). You are also learning to use the verb form 'shindō suru' in different tenses. 'Shindō shimashita' (It vibrated) or 'Shindō shinai' (It doesn't vibrate). You might see this word on signs in Japan, especially near construction sites or on public transport. Understanding this word helps you follow instructions like 'Please turn off the vibration' or 'Beware of vibrations.' You can also start to use basic adjectives with it, like 'tsuyoi shindō' (strong vibration) or 'chiisai shindō' (small vibration). This level focuses on connecting the word to daily inconveniences or settings on your electronic devices.

At the B1 level, you should understand 振動 (shindō) in more varied contexts, including health and basic science. You can describe how a sound 'vibrates' through a wall or how a machine's vibration affects its performance. You should be comfortable using the word in compound nouns like 'shindō-dome' (vibration dampener/stopper). You can also use it to explain problems: 'Kono kikai wa shindō ga hageshii node, koshō kamo shiremasen' (This machine vibrates violently, so it might be broken). You are now expected to know the kanji (振動) and recognize them in manuals or news reports. You should also be aware of the difference between 振動 and 震度 (shindo - earthquake scale), as this is a common point of confusion. At this level, you can use the word to discuss more abstract concepts, like the 'vibration' of a musical instrument's strings or the way a speaker works. Your vocabulary is expanding to include the causes and effects of these vibrations.

At the B2 level, 振動 (shindō) becomes a tool for technical or professional description. You can use it in the context of engineering, physics, or high-level manufacturing discussions. You should understand terms like 'resonance' (共振 - kyōshin) and how it relates to 振動. You can discuss the 'frequency' (振動数 - shindōsū) of a wave and how it impacts sound quality or structural safety. In a business meeting, you might discuss 'vibration resistance' (耐振性 - taishinsei) of a product. You are also able to use the word metaphorically, though it's less common than in English; you might talk about the 'vibration' of a voice or the 'vibrations' of a particular atmosphere in a poetic sense. You should be able to read technical reports that use 振動 to describe data from sensors or experiments. Your understanding of the word now includes its mathematical and physical properties, not just the physical sensation.

At the C1 level, you have a nuanced understanding of 振動 (shindō) and can use it in complex, academic, or literary contexts. You can discuss the philosophical implications of 'everything is vibration' or analyze the use of the word in Japanese literature to describe subtle environmental changes. You are familiar with highly specialized terms like 'forced vibration' (強制振動 - kyōsei shindō) or 'damped oscillation' (減衰振動 - gensui shindō). You can explain the difference between 振動 and other types of motion like 脈動 (pulsation) or 波動 (wave motion) with precision. In a professional engineering or scientific environment in Japan, you can lead discussions on how to mitigate 振動 in high-precision equipment. You also understand the cultural nuances, such as how 振動 is treated in Japanese law regarding 'environmental pollution' (公害 - kōgai). Your command of the word allows you to use it with perfect register, whether in a casual chat about a phone or a formal presentation on mechanical engineering.

At the C2 level, your mastery of 振動 (shindō) is indistinguishable from a highly educated native speaker. You can engage in deep scientific discourse on quantum mechanics, where 振動 refers to the zero-point energy of particles. You understand the historical evolution of the word and its kanji. You can appreciate and use the word in high-level legal or regulatory contexts, such as the 'Vibration Control Act' (振動規制法). You can interpret the word in the context of avant-garde art or music theory, discussing how 振動 interacts with space and human perception. Your ability to use synonyms like 'shōgeki' (impact) or 'fukko' (oscillation) allows you to avoid repetition and provide exact descriptions. You can also identify and correct subtle misuses of the word in others' speech or writing. At this level, 振動 is not just a word for 'shaking,' but a fundamental concept of the physical universe that you can manipulate linguistically with ease and sophistication.

振動 em 30 segundos

  • Vibration is the rapid back-and-forth movement of an object, commonly used for smartphones, machinery, and sound waves in both casual and technical Japanese contexts.
  • The word is composed of two kanji: 'shin' (to shake) and 'dō' (motion), emphasizing a rhythmic and mechanical type of shaking rather than a slow sway.
  • It functions as a noun (shindō) or a suru-verb (shindō suru), making it versatile for describing states or actions in everyday and professional environments.
  • Key distinctions include its use for machines versus 'yureru' for swaying and 'furueru' for human shivering, as well as avoiding confusion with 'shindo' (earthquake scale).

The Japanese word 振動 (しんどう - shindō) is a formal and technical noun that refers to a physical back-and-forth motion or vibration. While it is classified here for A1 learners to introduce the concept of 'shaking' in a modern context (like a smartphone), it is actually a word that carries significant weight in scientific, mechanical, and engineering fields. At its core, 振動 represents a repetitive movement around a central point of equilibrium. Imagine a guitar string plucked; the rapid movement it makes that produces sound is exactly what 振動 describes. In everyday life, the most common encounter with this word is through technology. When your phone is on 'manner mode' and it buzzes in your pocket, that is 振動. The kanji themselves provide a clear map to the meaning: 振 (shin) means to shake, brandish, or swing, and 動 (dō) means motion or movement. Together, they create the concept of 'shaking motion.'

Physical Property
It describes the periodic oscillation of a medium or object. This can be visible, like a bridge swaying in the wind, or invisible, like sound waves traveling through the air.
Technological Context
Used extensively to describe haptic feedback in devices. If a game controller rumbles, it is experiencing 振動.
Scientific Nuance
In physics, it refers to the variation, typically with time, of the magnitude of a quantity with respect to a specified reference when the magnitude is alternately greater and smaller than the reference.

"このスマートフォンの振動はとても強いです。" (The vibration of this smartphone is very strong.)

It is important to distinguish 振動 from other types of shaking. For instance, 揺れ (yure) is a more general term for swaying or shaking, often used for earthquakes or a boat on water. 振動 is usually more rapid, mechanical, or rhythmic. When a large truck passes by your house and the windows rattle, that specific rhythmic rattling is 振動. In a medical or biological sense, it can refer to the vibrations felt in the chest when speaking or the mechanical vibrations used in certain therapies. The word implies a certain level of frequency; if the movement is too slow, we might call it yure, but if it's a fast 'buzz,' it's definitely shindō.

"工事の振動で家が揺れています。" (The house is shaking due to the vibration from the construction.)

Acoustics
Sound is essentially the 振動 of air molecules. Without this motion, there is no sound.
Industrial Safety
Workers using jackhammers must be careful of 'vibration disease' (振動病), caused by excessive 振動.

Using 振動 (shindō) correctly requires understanding its role as a noun and its ability to transform into a verb. As a noun, it functions simply to name the phenomenon. You can modify it with adjectives or use it as the subject or object of a sentence. For example, 'strong vibration' is 強い振動 (tsuyoi shindō). However, to say something 'vibrates,' you add the verb suru (to do), making it 振動する (shindō suru). This is a very common pattern in Japanese for Sino-Japanese words (kango).

"エンジンが激しく振動し始めました。" (The engine began to vibrate violently.)

In technical writing, you will often see 振動 paired with other nouns to create compound terms. For example, 振動数 (shindōsū) means 'frequency' (literally 'vibration number'). In the context of smartphones, you might see 振動設定 (shindō settei) for vibration settings. When describing the cause of the vibration, use the particle による (due to) or で (at/by). For instance, 'vibration caused by the wind' is kaze ni yoru shindō.

Grammar: Noun + する
振動する (To vibrate). Example: 携帯が振動する (The phone vibrates).
Grammar: Noun + の
振動の強さ (The strength of the vibration). Using 'no' to connect to another noun.
Grammar: Particle を
振動を抑える (To suppress/dampen vibration). Used when you are acting upon the vibration.

For A1 learners, the most practical use is describing your phone or a machine that isn't working right. If you go to a repair shop, you might say, "Okashii shindō ga arimasu" (There is a strange vibration). While 'yure' might be understood, 'shindō' sounds more precise when talking about machinery. It's also used in the context of music and sound. A speaker 'vibrates' to produce bass; this is 振動. If you are describing the feeling of a loud concert where you can feel the music in your chest, you are feeling the 振動 of the sound waves.

"この機械は振動が少ないので、とても静かです。" (This machine has little vibration, so it is very quiet.)

You will encounter 振動 (shindō) in several distinct environments in Japan. The most common is likely the electronics store or when reading a manual for a new gadget. Japan's obsession with 'manner mode' (silent mode) means that the word for vibration is everywhere. In train stations, you might see signs or hear announcements about the shindō of the platform when a high-speed train passes through. It is a word of caution and a word of technical specification.

Public Transportation
Announcements regarding the movement of the train or the 'shaking' felt on the platform.
Construction Sites
Signs apologizing for 'noise and vibration' (騒音と振動 - sōon to shindō) are ubiquitous in Japanese cities.
Weather Reports
While 'shindo' (震度 - seismic intensity) is used for earthquakes, 'shindō' (振動) might be used to describe the physical rattling of buildings during high winds.

"工事の振動にご協力をお願いします。" (We ask for your cooperation regarding the construction vibration.)

In a professional or academic setting, 振動 is a key term in physics and engineering lectures. If you are studying in Japan, you'll hear it in discussions about wave mechanics, resonance (kyōshin), and structural integrity. In the automotive industry, reducing NVH (Noise, Vibration, and Harshness) is a major goal, and 振動 is the 'V' in that acronym. You'll also hear it in medical contexts, such as when a doctor uses a tuning fork to test hearing or nerve sensitivity; the vibration of the fork is 振動.

"ドラムの振動が床から伝わってくる。" (The vibration of the drums is coming through the floor.)

The most frequent mistake learners make with 振動 (shindō) is confusing it with the homophone 震度 (shindo). While they sound almost identical to the untrained ear, they have very different meanings. Shindo (震度) refers specifically to the seismic intensity scale used in Japan to measure how much the ground shakes during an earthquake (e.g., Shindo 5). Shindō (振動) is the general physical phenomenon of vibration. If you say 'The earthquake was 振動 3,' it sounds like you're talking about a mechanical buzz rather than a seismic event.

Mistake 1: Shindō vs. Shindo
Confusing general vibration (振動) with earthquake intensity (震度). Remember the long 'o' in shindō for machines.
Mistake 2: Shindō vs. Furueru
Using 'shindō' for people. If a person is shivering from cold or fear, use 'furueru' (震える). 'Shindō' sounds like the person has a motor inside them.
Mistake 3: Shindō vs. Yureru
Using 'shindō' for a swing or a swaying tree. These are slow, large movements. Use 'yureru' (揺れる) instead.

"❌ 寒くて体が振動している。 (My body is vibrating because it's cold.)"
"✅ 寒くて体が震えている。 (My body is shivering because it's cold.)"

Another common error is the misuse of the verb form. Some learners try to use shindō as a standalone verb without suru. In Japanese, Sino-Japanese nouns cannot function as verbs on their own. You must say shindō suru. Additionally, learners often forget that 振動 is a relatively formal/technical word. In very casual conversation about a table wobbling, using 振動 might sound a bit too 'science-classroom.' In that case, gata-gata (onomatopoeia) or yureru would be more natural.

Understanding 振動 (shindō) becomes easier when you compare it to its synonyms and related terms. The Japanese language has a rich vocabulary for different types of movement, and choosing the right one adds precision to your speech. The most common related word is 揺れ (yure). While 振動 is fast and often mechanical, 揺れ is the general word for shaking, swaying, or rocking. You feel yure on a boat or during an earthquake. 振動 is what you feel when you touch a running refrigerator.

震動 (Shindō)
Wait, another shindō? Yes, written with '震' (earthquake/shake). This version is often used for the physical shaking of the ground or large structures caused by an impact or explosion. It's more 'violent' than the standard 振動.
脈動 (Myakudō)
Pulsation. This is a rhythmic 振動, like a heartbeat or the pulsing of blood through veins. It implies a 'pulse' rather than a constant buzz.
波動 (Hadō)
Wave motion or undulation. Used for sound waves, light waves, or spiritual 'vibes' (though 'aura' is more common for the latter). It describes the propagation of 振動 through a medium.

"地震の揺れと、トラックの振動は違います。" (The shaking of an earthquake and the vibration of a truck are different.)

There is also 震え (furue), which is the noun form of furueru. This is almost exclusively used for living things—shivering from cold, trembling from fear, or a voice quivering with emotion. You would never say a smartphone has a furue; it has a shindō. Conversely, you wouldn't say your hands are shindō-ing unless you're a robot. Lastly, consider the onomatopoeia: biri-biri (electric vibration), gata-gata (rattling), and bura-bura (swinging). These are often used in daily life instead of the more formal 振動.

Erros comuns
  • Using 振動 for a person shivering from cold.
  • Confusing 振動 (shindō) with 震度 (shindo) in earthquake contexts.
  • Forgetting to add 'suru' when using it as a verb.
  • Using 振動 for the slow swaying of a tree or a bridge.
  • Misspelling the kanji as 震動 when general vibration is intended.

Dicas

Suru-Verb Usage

Remember that 振動 is a noun that becomes a verb with 'suru.' Always use 'shindō suru' for 'to vibrate.' This is a standard pattern for many Sino-Japanese words.

Long Vowel

Pay close attention to the long 'o' at the end of 'shindō.' Without it, you are saying 'shindo,' which means earthquake intensity. The distinction is vital in Japan.

Phone Etiquette

When in Japan, use the word 振動 to ask about phone settings. 'Shindō ni shite kudasai' means 'Please put it on vibration mode.' It shows you understand local manners.

Shindō vs Yure

If it's a 'buzz,' it's 振動. If it's a 'sway,' it's 揺れ. This simple rule will help you choose the right word 90% of the time.

Kanji Components

The left part of 振 is the 'hand' radical, suggesting a manual shake. The right part of 動 is 'power,' suggesting movement driven by force. This helps in remembering the meanings.

Construction Signs

Look for 振動 on construction signs. It's usually paired with 騒音 (sōon - noise). It's an apology for the disturbance caused by heavy machinery.

Frequency

If you study science in Japanese, 振動数 (shindōsū) is your word for frequency. It literally translates to 'vibration count.' It's easier to remember than the English term!

Instrument Strings

When talking about guitars or violins, the movement of the strings is always 振動. This vibration is what creates the sound waves (hadō).

Vibration Disease

In Japan, 振動病 (shindō-byō) is a recognized occupational hazard for those using vibrating tools. It shows how serious the concept of 振動 is in the workplace.

Appliance Noise

If your washing machine is too loud, tell the landlord 'shindō ga hageshii' (the vibration is intense). It sounds more specific and helpful than just saying it's 'noisy.'

Memorize

Origem da palavra

Sino-Japanese (Kango)

Perguntas frequentes

10 perguntas

While an earthquake causes 振動 (vibration), the specific scale used to measure it is called 震度 (shindo). You would say 'The earthquake's shaking (yure) was strong,' but you wouldn't usually say 'The earthquake's 振動 was level 3.' Use 振動 for the physical buzz felt from a passing truck or machine.

No, that sounds like your hands are mechanical parts. For human hands shaking due to cold, nerves, or illness, use 震えている (furuete iru). 振動 is almost exclusively for inanimate objects or scientific phenomena.

In Japan, 'manner mode' is the silent setting on a phone. It relies on 振動 (vibration) to alert the user without making noise. It is considered polite to use this in public spaces.

You say 振動数 (shindōsū). This is a common term in physics and music to describe how many times something vibrates per second (Hertz).

They are both pronounced 'shindō.' 振動 is the general term for any vibration. 震動 (using the earthquake kanji) is used for more violent, impactful shaking, like that from an explosion or heavy impact.

Yes, but it's formal. You might hear 'vibrations of the soul' in a song or 'political vibrations' in a news report, but 'yure' or 'shōgeki' (shock) are more common for metaphors.

Yes, it is very common in technical, industrial, and daily technological contexts. Every smartphone user in Japan knows this word.

It is written as 振動. The first kanji 振 means 'to shake' and the second 動 means 'to move.' Together they mean 'shaking motion.'

Yes, 'biri-biri' is often used for the electric buzzing feel of 振動. 'Gata-gata' is used for a rattling vibration.

Yes, by adding 'suru.' 振動する (shindō suru) means 'to vibrate.'
