types of phonographs: they are mainly distinguished according to their shapes. The principles and functions of different types of phonographs are not very different. According to their styles, they can be roughly divided into box phonographs, desktop phonographs, vertical phonographs and cabinet phonographs.
the function of the phonograph: it is not only used as audio and music playing equipment, but also used as indoor decoration, gift giving and art collection. Detailed > >
phonograph structure
1. turntable: the phonograph turntable is used to place records and drive the records to rotate, so that the phonograph needle can read the analog signals on the vinyl records, thus making sound.
2. Loudspeaker: Loudspeaker is the symbol of the phonograph. Because the sound read by the stylus is very small, it was used to amplify the sound at that time, and now it is generally used to play high notes.
3. Singing arm: The front end of the singing arm is the singing head, followed by a revolving device. Now, there is generally an automatic arm retracting function of the phonograph, that is, after the vinyl record on the phonograph disc is played, the singing arm is automatically retracted, the singing arm is retracted, and the disc automatically stops playing.
4. Singing head: The main part of the singing head is the stylus, which is also one of the main parts of the phonograph. The analog signal of the stylus is converted into vibration, and the vibration signal is transmitted to a special membrane, which reproduces the sound pressure, turns it into sound, and then amplifies it through the loudspeaker.

the principle of the phonograph The reason why the phonograph can automatically produce sound is mainly because the stylus senses the sound produced by the record.
To make the phonograph sound, you need to put a special record. When making a record, you will leave different shades on the record according to the strength of the audio. After putting the record on the turntable of the phonograph, the needle of the phonograph can sense these notches, and then the current will be induced through the coil, and the sound will be made after being amplified by an amplifier.

Who invented the phonograph? The inventor of the phonograph is generally considered to be Thomas Alva Edison. On November 21, 1877, American inventor Edison announced that he had invented the first phonograph, a device for recording and replaying sound. On November 29 of the same year, he demonstrated this device for the first time and obtained a patent on February 19, 1878.
But before Edison, there were also some people who contributed to the invention of the phonograph. The earliest phonograph recording device was the acoustic vibrometer, which was invented by a Frenchman, Scott de Martinville. It can transcribe sound into a visual medium, but it cannot be played after recording. In 1877, a French scientist, Charles Cross, put forward a principle about the phonograph, but he didn't make a model. His principle was submitted to the French Academy of Sciences and published in December 1877. By that time, Edison had already made a model. Therefore, the phonograph is thought to have been invented by Edison. Detailed > >
The difference between a record player and a CD player
1. Different structures
A vinyl record player consists of a base, a turntable, a singing arm and a singing head. CD player is mainly composed of laser pickup and turntable system, servo system, signal processing system, information storage system and control system.
2. Different principles
The vinyl record player plays music through sound-electrical signal-mechanical signal-disc grain; CD player generates sound by digital sampling-recording digital signal, decoding digital signal and then simulating sound signal.
3. Different sound quality effects
Which sound quality is better, a vinyl record player or a cd player? The sound quality of vinyl records played by vinyl record players is usually more real and warm than that of CD players, and the definition may be slightly worse.
4. Different prices
There are several vinyl record players ranging from several hundred yuan to ten thousand yuan, and the better ones usually cost several thousand yuan, which is much more expensive than the same quality CD players. Detailed > >
How to choose a record player to see the sound quality performance? The main advantage of a record player lies in the sound quality performance, and the factors that depend on the sound quality performance of a record player mainly include the type of stylus and the speed. The type of stylus determines the clarity of the record player, while the rotation speed affects the performance of high and low sound effects. Their good or bad performance, * * * determines the sound quality of the record player.
stylus: the finer the stylus, the higher the definition, but it doesn't mean that the clearer the better. For beginners of record player, it is enough to choose the most common and non-perishable round stylus. If you are a professional enthusiast, you will feel more delicate and maintain the stylus. It is better to choose an oval or super-oval stylus with a thinner tip.
rotational speed: generally speaking, it is better to choose a record player with 331/3 rotational speed. If you are a collector or a enthusiast, you can choose a higher speed of 45 or 78 to meet more auditory effects. Detailed > >
Look at the production process. For a record player, its production process is also very important. According to the needs of different groups of people, designers will divide the production process of record players into two types: integrated production and independent production.
The record player made in one piece will be relatively simple in subsequent connection and use, and no additional equipment is needed, so it is more suitable for beginners with experience as the main choice.
The independent record player is suitable for enthusiasts because there are many devices to be connected, and its professionalism is also high, and it can't play the best effect without some technical content.
Look at the playback mode. The first playback mode of the record player is only manual operation, and there will be no automatic playback as it is now. Those who can master the former can basically be defined as professional enthusiasts, while beginners are mainly the latter.
for automatic playback and manual playback, it still depends on your professional level. If you haven't touched a record player before and don't know anything about its operation, it's safer to choose an automatic playback record player.
phonograph price How much is a vinyl record player? The editor who understands the TV network understands that the specific price of the phonograph is influenced by many factors, including size, material, brand and style. Some small phonographs can be bought for 3 to 5 yuan, the better ones generally cost 1, to 2, yuan, and some phonographs with collectible value even cost tens of thousands of yuan each. Detailed > >

Put your favorite phonograph vinyl record on a clean turntable, take off the protective cover of the singing head, unlock the singing arm, slowly put the needle of the phonograph on the record, and the record will rotate automatically, and the music on the vinyl record will be played automatically.
2. After all the contents on the phonograph record are played, the long arm will automatically retract into the singing arm slot, and the vinyl record will stop rotating.
3. If you want the phonograph to stop playing music, you can gently lift the singing arm and put it back in the singing arm groove. To repeat music, the same is true, just lift the singing arm and put it back on the edge of the record.
Maigoo tip: after listening to vinyl records once, you have to wait six hours before you can listen to them again. This can prevent the high heat generated by friction when the stylus is played on the record, which will soften the plastic groove of the record.
Does the record player need external audio?
Generally speaking, whether the vinyl record player needs external audio depends mainly on its production method. There are two production processes for the record player: integrated production and independent production:
1. The integrated production does not need
the integrated record player does not need external speakers or amplifiers, because the amplifier and speakers are designed in the record player in advance when it is produced.
2. Independent production needs
The record player made independently has high professionalism, and can concentrate more on the reading of records, without too many interference factors affecting the sound quality. However, because of the independent design, it is necessary to match the amplifier or active speaker when using it to achieve the sound playback effect.

frequently asked questions about phonograph troubleshooting and maintenance 1. The turntable of phonograph doesn't turn
① Remove the central locking piece of the turntable, open the plastic turntable of the turntable, and check whether the drive belt of the internal movement of the phonograph falls off. ② Check whether the card switch in the movement is in normal contact. ③ Check whether the connecting wire between the movement and the motherboard falls off or has poor contact.
2. The phonograph is distorted
① Check whether the turntable scratches the wooden case panel. ② Check whether the three-speed changeover switch is selected correctly. ③ Check whether the stylus deviates from the card position. How to adjust the balance of singing arm of vinyl record player > >
3. The needle jumps when the phonograph plays
① Check whether there are obvious scratches on the track of the record. ② Replace the stylus. Detailed > >
How to adjust the noise in the record player: there are quality problems (such as scratches) in the record, dust on the stylus, the angle of the head of the record player is not adjusted properly, the turntable and turntable are not kept at a horizontal angle, vibration interference, and acoustic problems.
Solution: First, find the problem from the record and replace it with a good vinyl record. If there is no problem, it means that it is a record problem, not a record player problem. Just clean or replace the record. If there is still noise, adjust the record player. If there are no problems in the above, we can see if there are problems in acoustics, wire or electric frequency interference, etc. Detailed > >
how many times can a vinyl record be listened to? The loss is actually very small, and it won't be broken after listening to it for a hundred times. At present, the needle pressure of the head used is generally about 1.5 grams, and the tracking angle and sideslip force are adjusted accurately, which has little damage to the record. And generally, I don't listen to the same record repeatedly every day, so it's hard to hear the sound quality of the record decline naturally unless it is artificially damaged.
how often do you change the needle of a record player? The needle of a vinyl record player is made of different materials, used with different frequencies, and the replacement time is different. Generally, the ordinary needle can be replaced after being used for more than 3 hours, and the one with better materials can wait for 1, hours. In fact, the damage of the stylus is often man-made damage rather than natural wear. If the playback is hoarse, distorted, and the needle jumps, you can consider replacing the stylus. Detailed > >
cleaning and maintenance of the classical phonograph
1. Sunlight: Do not expose the solid wood classical phonograph to direct sunlight. Over time, the paint on the surface will fade, the metal fittings will be oxidized, and the plastic fittings will easily become brittle. The vinyl LP is generally made of PVC, and the sunlight will deform it.
2. Dust: dry cotton rag is selected, and fine soft brush is used to remove the dust in the concave or embossed patterns. Avoid using solvents such as water, alcohol and gasoline to wipe the stains, then use colorless wax polish to spread them thinly, and dry them with cotton cloth to reduce dusting and enhance luster.
3. Humidity: Humidity will make the wood rot, the metal fittings rust, the adhesive parts open, and the chromium-plated original parts take off the film.
4. Stains: When the pure white lacquer classical phonograph turns yellow, gently wipe it with pure white cotton gauze dipped in a little toothpaste, then remove the toothpaste stains with a wet cloth, and then dry it with a dry cloth. The yellowing phenomenon can be improved.
5. Hot marks: For the painted classical phonograph, white-gray hot marks appear when you put it directly into the boiling water cup or hot soup bowl, you can dip a cloth in a little strong tea water or toilet water and a little alcohol, wipe it gently, and then wipe it dry with a cloth.
6. Cracking: Retro phonographs are mostly made of wood, and wood is easily affected by environmental humidity, which changes when it swells and shrinks. In order to prevent cracking, attention should be paid to maintaining indoor humidity. You can put a humidifier, a basin of water or some plants that are beneficial to indoor moisturizing.
