The speakers used in professional audio engineering are divided into two categories according to their use, one is a sound reinforcement box; the other is a monitor speaker. Because these two types of speakers are different from each other, the design focuses on different functions and functions. When selecting a speaker , it must be reasonably selected according to its correct use.
Speakers are classified by purpose
1. Sound reinforcement box <br> Most of the sound reinforcement boxes in professional sound engineering are high-power, wide-band, high-level speaker systems. In order to better control their sound field, high-frequency units are usually reinforced with horn loudspeakers. Its sound pointing power, the sound box in professional sound engineering is more sensitive to operate, in the conference room sound system usually through the sound box system to the audience to deliver sound.
2, monitors <br> professional audio engineering monitors means available to professional audio engineer monitors field use. These speakers have strong fidelity and excellent dynamic characteristics, and refuse to modify and modify the scene to truly convey the original effect of the live sound. Monitor speakers are generally seen as "no personality" speakers . The main purpose of the monitor speakers is not to render the scene, but to monitor the scene to find the problems and defects of the program sound in a timely and accurate manner.
Speakers are classified according to structure. Professional speaker systems in audio engineering are available in a variety of styles, including closed, inverted and horn speakers . Among them, closed and inverted are the two most common types.
1. Closed-type speaker <br> The cabinet of the closed-type speaker in professional sound engineering is completely sealed. It completely seals the sound wave behind the speaker inside the box and is completely isolated from the front of the speaker. Closed professional speakers are also known as "air cushion" speakers . A well-designed, closed professional speaker that enhances playback at low frequencies. Closed-type speakers are simple in design and relatively large in size, and are widely popular in Western countries.
2. Inverted speaker Compared with the closed speaker , the inverted speaker is a more popular mode in China. Its structural features are high efficiency and relatively small size, but the design is more complicated than the closed speaker . There are 1~2 inverted tube holes on the panel, so that the sound waves behind the speaker can be transmitted from the inverted tube hole to enhance the sound power emitted by the speaker. Because the structure design of the inverted speaker is more stringent, it is difficult to buy a speaker with excellent performance. In addition, Dongcheng Audio has a professional audio engineer team to help you select high-quality inverted speaker , if necessary, welcome to consult.
3, horn speaker professional audio engineering horn speaker refers to the front or rear of the speaker of additional wooden horn speakers. In general, in order to control the body shape of the speaker , the horn will be designed in a bent shape. The high-frequency performance of the horn loudspeaker is mainly used in large professional audio engineering systems.
Classified by size speakers 1, floorstander floor speaker speaker means larger size, to be placed directly on the floor speaker. Floor-standing speakers are usually equipped with a large woofer, so the low-frequency effect is excellent, the frequency response range is wide, and the power is large. However, because of the large number of speakers, the sound positioning is usually not as clear as the bookshelf speaker . In the professional audio engineering system, the floor-standing speaker is more consistent with the positioning of the movie speaker .
2, bookshelf speakers are small in size, need to stand up separately when using, a certain distance from the ground. Because the number of speakers is small and the aperture is small, the sound positioning is usually more accurate, but there are also defects of low power and low frequency effect. In professional audio engineering systems, it is generally used as an auxiliary speaker , such as a monitor speaker . In a professional audio engineering system, when using a bookshelf speaker to play songs or light music, the effect is usually better than a floor-standing speaker .
Gun Drills
GUN DRILLS with its ability to Machine very straight deep holes and hold excellent ï¬nishes, was originally developed for gun barrel manufacturing. Today, this drill is designed for deep hole drilling in virtually any material.
The gundrill requires high-pressure coolant through the tool, keeping the cutting edges lubricated and providing adequate chip evacuation down the flute channel. OPT gun drills product line diameter range is .039" [1.00mm] through 1.500" [38.10mm] as a solid carbide head.
Larger diameter tools are available using a brazed inserted blade design. All gundrills can be made to any speciï¬c length. Lengths over 72" [1828 mm] will have an additional weld joint in the body of the tool.
The gundrill is designed to drill holes from solid material, and can produce bottom hole conï¬gurations, and minimize burr at intersections. The gundrill can achieve precision holes in one pass thus eliminating the need for secondary passes, and is a tool for consistent hole-to-hole reproduction.
