A well-matched high-fidelity sound system is not the only factor in an excellent sound system . The acoustic conditions and components of the room, especially the speaker, are optimally placed to determine the final result of the sound system . The proper placement of the speakers can make the normal system perform well, but if it is placed improperly, it can make the expensive system effect worse. The common principle of audio fans is that the sound is best projected along the room, and the stereo sound of the speaker is at least six to eight inches. Because the speakers are separate, your listening position should be farther away from the speakers, and avoid sitting on the back wall to prevent the bass from sinking too much.
The distance between the speaker and the front wall affects the bass response of the system. Therefore, whether you use bass reflex or closed speaker design, it is best to place the speaker close to the front wall. When adjusting the distance, increase it by 5 to 10 cm at a time until the bass is compared with the overall sound. Strong will not be too weak to get the best sound balance. It is best not to attach the speaker to the wall to avoid rumbling. The distance from the wall also varies with the specific speaker design and size, as well as the room furnishings. To enjoy the best results, you must also pay attention to the height and the axial direction. The height of the listening is based on the distance of the tweeter from the ground. The best axis is when the speaker is seated, the height of the speaker can be aligned with the height of your ear.
In addition to good speaker placement, the source components and amplifiers must also be as far away as possible from the speakers. The vibration generated by the speaker has an adverse effect on sensitive audio electronic components. The audio components should be placed as close as possible to the stack, but should be placed on a stable shelf with sufficient vibration buffer space. Keep the wiring between components and speakers as short as possible to shorten the signal path. Never put it together with the power cord and put it in parallel to avoid electromagnetic flow and distortion. Also make sure that all wiring is tight, as loose contacts can interfere with signal transmission and cause poor sound. All of the above are general principles and practices that ensure the most effective effects. Speaker placement, component placement, and attention to wiring are all great tools for maximizing the system's potential. The most important thing is that it's free. The high sound, midrange and bass of a good sound system must have a good balance - each one is complementary, not competing with each other.
How to improve the acoustic conditions of the auditorium?
From adding simple curtains to specially designed acoustic treatments, the acoustic conditions of the listening room can be improved, but the latter is usually expensive. Just add or remove general furnishings, such as good sound-absorbing materials such as carpets and curtains, and even put a shelf book, which is the best spreading body, can improve the sound quality. But don't put too many sound-absorbing or spreading elements. Because the direct sound of the speaker and the reflected sound of the wall are the beautiful performances we hear, if there are too many sound-absorbing and spreading elements in the room, the sound will sound "dead" and there is no real sense. Place some uneven surfaces or objects, such as furniture or structures, especially near the viewing position, to eliminate the waves. However, it must be remembered that all acoustic processing must first position the speaker.
What kind of room size is best for the sound system ?
Unless there is a specially designed listening room, there is actually no absolute standard, because each family's furniture, walls and so on are different. However, according to the basic acoustic principles, audio fans think that a rectangular room is better than a room close to a square. The sloping ceiling is also good because the standing waves reflected by the ceiling are easily dissipated. There is a way to find a good room size, that is, you can be somewhere else, maybe a friend's home or dealer's showroom, when you hear good sound, pay attention to the size and characteristics of the room. Although the sound system there may be very different from your own, the overall sound quality is still worthy of reference. The general rule is that a large room will be better than a small room, because the room echo that affects your feelings is easier to spread. Simple interiors such as curtains, rugs, potted plants and open book shelves provide a good sound.
Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
