The construction principle of the earpiece, the structure of the earpiece, what is the structure of

There will be a small film inside the microphone and the earpiece, and the film in the microphone will act as the eardrum in the human ear, and when you speak to it, the film will vibrate, and the film will be connected to a small coil (note: this coil will change position with the vibration of the film), and there is a small fixed permanent magnet in the microphone (fixed to the microphone housing). The film is elastic and generally acts as both a vibration and a pull-back coil back to its initial position.

The membrane is attached to the microphone housing at one end and a coil at the other.

When the film vibrates, the coil is driven to vibrate, and the relative position of the coil and the permanent magnet changes, which makes the magnetic field through the coil change, and the magnetic field changes will induce electromotive force in the coil, which will also generate current. A particular sound has a specific vibration, and a particular vibration produces a specific form of electric current. So the microphone "encodes" the sound into the form of an electric current.

The principle of the earpiece is probably the reverse process of the microphone, and the structure is almost the same. There is also a membrane in the earpiece, which is connected to a coil, and there is also a permanent magnet. A certain form of electric current (such as the current that the microphone has just "encoded") flows through the coil of the earpiece, which causes the magnetic field generated by the coil to change, so that the magnetic force between the permanent magnet and the coil changes, and therefore the distance between the permanent magnet and the coil changes.

This causes the film to vibrate and make a sound.

The working principle of the microphone is: when a person speaks into the microphone, the sound wave causes the diaphragm to vibrate, and the diaphragm squeezes the carbon particles loosely and tightly, and the resistance changes accordingly, and the current that changes with the sound vibration is generated in the circuit, that is, the microphone is equivalent to a variable resistance.

The working principle of the earpiece is: when the current that changes in strength and weakness with the vibration of the speaking sound comes from the microphone, the attraction of the electromagnet to the iron sheet also changes, so that the iron sheet vibrates and produces the same sound as the other party's speaking voice, that is, the earpiece is equivalent to an electromagnet.

The structure of the earpiece is: listening (left and right structure) and tube (upper and lower structure).

The structure of the earpiece is: listening (left and right structure) and tube (upper and lower structure). Pinyin is: tīngtǒng. The part of speech is: noun. The phonetic pronunciation is: one

What is the specific explanation of the earpiece, we will introduce it to you through the following aspects:

1. Explanation of terms [click here to view the details of the plan].

Earpiece tīngtǒng. (1) Headphones. (2) A device in the machine that converts the pulsating or changing current of the electric spring return into sound. (3) Stethoscope.

2. Citations and Explanations.

i.e. headphones. Yin Hongshen's "Young Master Feng: Movie Story": "The electricity for teenagers is coming again, and the young man asks who is with the earpiece loudly, and the young man is shocked when he hears the man's voice, and the earpiece falls down.

Mao Dun's "Midnight" seven: "** from the factory!" I don't know if it's good or bad?

When he picked up the earpiece, his hands were shaking a little. A colloquial name for a stethoscope.

3. Chinese dictionary.

** Receiver of the machine.

Fourth, the network explained.

Headphone, also known as headphone or earpiece, is a pair of conversion units, which accepts the telecommunication signals sent by the device or receiver, and converts them into audible sound waves by using a speaker close to the ear. The headset is generally detachable from the **** device and is connected by a plug. The advantage is that you can listen to the sound alone without disturbing others; It can also be used to isolate the sound of the surrounding environment, which is useful for people who use it in noisy environments such as recording studios, DJs, travel, sports, etc. (closed-back headphones).

Headphones were originally used for ** and radio, but with the popularity of portable electronic devices, headphones are mostly used in mobile phones, Walkmans, radios, portable video games and digital audio ** devices, etc., and are also quietly used in computers and Hi-Fi audio.
