How does the principle of electric guitar sound?

Electric guitar is an instrument that many people want to learn now, but many people don't know how to pronounce it. The following is the knowledge I brought to you about the sound principle of electric guitar. Welcome to read!

The sound principle of electric guitar is a kind of plucked instrument, is it George? Beacham and Adolf? Rickenbacker.

Different from the traditional guitar, its sound principle is not based on the vibration of the box, but on the electromagnetic principle. Its body is solid wood, not an empty speaker. A coil is installed on the piano. They are called pickups. When the guitar string vibrates, the magnetic induction line of the pickup is cut off, so that currents with different frequencies are generated in the wires in the piano body. When these currents are restored through electronic speakers, they become the sound of electric guitars.

Sound principle of guitar 1. Fingers pluck the strings and they start to vibrate.

2. When the guitar strings vibrate, this vibration will be transmitted to the piano code.

3. The piano code transmits vibration to the panel.

4. The vibration of the panel and the piano body compresses the air vibration in the box to generate sound waves.

5. The sound is transmitted from the sound hole through the reflection of the backboard.

From this process of vibration transmission, we can see that for a finished guitar, the only step that we can influence the timbre of the guitar in this process is the first step, to control the vibration of the strings.

Now let's pick up the guitar and observe the connection between the guitar code and the strings. What did you find? The fixing of the strings at the piano code is two points! One is the bridge that supports the strings, and the other is the piano code that fixes the strings. They fix the strings in two directions, that is, the bridge supporting the strings is responsible for transmitting the downward pressure generated by the vibration of the strings, while the piano code is responsible for transmitting the upward tension.

When a string vibrates, it will produce tension changes along the chord direction. When the tension becomes tight, the bridge will exert downward pressure on the panel, and the code will exert upward pulling force to pull the panel, so the panel in front of the bridge will move downward and the panel behind the code will move upward. When the tension is restored, the state of the panel is restored, thus generating continuous up-and-down torsional vibration.

The structure of electric guitar constitutes the sound generating device.

Compared with the traditional acoustic guitar, the electric guitar has fewer speakers and the body is made of solid wood.

The pronunciation of electric guitar is realized by connecting electromagnetic pickup (pickup) and sound box (speaker), so the pronunciation volume can be adjusted. Because of getting rid of the limitation of * * *, the range of guitar has been expanded and the expressive force of high grip has been greatly enhanced. In addition, because the volume of electric guitar can be large or small, and the sound value can be long or short, compared with acoustic guitar, it has more room for manoeuvre in performance, and it is more comfortable in the expression of glide, vibrato and tilt (which are the outstanding characteristics of guitar instruments). Moreover, the timbre of electric guitar can be changed and modified by various effectors to achieve different effects, thus playing different styles of music, which is the charm of this instrument. The electric guitar can only make sound through the amplifier, and the piano and the amplifier are connected through cables, and the piano and the speaker can also be connected through the wireless transmitter. When playing, it is usually necessary to connect various effectors and make various styles of sounds.

Qin Jing

The structure is similar to folk guitar, but the product number is increased to 22 or 24 or even more. Compared with folk guitars, electric guitars are more comfortable and expressive when played at high positions, and they use thin, soft and magnetic steel strings.

The connection between the neck and the body is generally divided into plug-in, screw-bolt connection and integral neck.

According to the shape, the neck can be divided into U-shaped, C-shaped and V-shaped to meet the needs of different hand players.
