Loudspeaker and loudspeaker system as an audio terminal, its quality is good or bad, will directly affect the sound effect of the whole sound system of play, so in order to meet the higher requirements of different environments and different audio equipment, in order to improve the sound effect of the whole sound system, engaged in the production of various foreign speakers have been committed to the development of new products the improvement of electrical properties, and constantly develop special new materials and new technology and the application of new design method. So a variety of loudspeakers have been introduced in recent years, which have the characteristics of high power, high efficiency and wide directivity.
At present, many foreign loudspeaker manufacturing companies are using new magnetic materials, using the new design method of the road, the flux balance, reduce to set up a new structure of driving source inductance and heat conduction, this makes magnetic magnetic material product can reach more than 3.6MGsOe, which increases the speaker bearing power capacity, increase the bass replay strength. Some loudspeaker diaphragm is made of titanium. The vibrating diaphragm made of this material makes the loudspeaker's high frequency greatly extended, and the power capacity has also been greatly improved. The bass loudspeakers are laminated with high density laminated paper. A flat line is used in the sound circle, because the flat line has high space occupying coefficient and high utilization rate of magnetic gap, so it can obtain high sensitivity.
Before the professional sound in the most commonly used horn is exponential, now with the progress of science and technology, a new directional horn, began to gradually replace the simple index. Directional horn is used in the side wall of different shapes, the past simple linear and exponential function becomes discontinuous type complex, in order to achieve constant directivity.
Cara OK, a loudspeaker, ballroom and home theater use along with the development of science and technology, emergence of new products, these new products are not only excellent technical performance, and high sensitivity, good transient response and dynamic range expansion. There are two frequency speaker speakers and three - way loudspeaker speakers.
Two frequency loudspeaker is composed of top treble unit with a 8 or 6.5 inch woofer Yingyu with the ball, if only a low frequency loudspeaker, in order to ensure the directivity and good phase characteristics, requires the speaker unit to have a wide range of piston vibration without segmentation vibration, but the effect is so low it is difficult to meet the requirements of the people, so in order to meet the bass effect, and have developed a dumbbell type loudspeaker, between two 8 inch or 6.5 inch woofer with a dome tweeter strengthen bass.
The three way split frequency loudspeaker box is based on two frequency divider, adding 1 pitch units, so that we can make full use of each unit's piston vibration frequency band, reduce distortion and improve power endurance. Both the two frequency or magnetic leakage have tri band with good performance.
In order to show the effect of the theater in a general home theater, the surround sound is very important. At present, the surround sound can be roughly divided into two kinds, namely, directional logic surround sound and DSP surround sound. DSP surround sound is the use of digital processing technology to simulate the acoustics of the theater, and the surround sound requires the front, middle and post indicator speakers to balance, and the directivity is ideal.
Most of the previous heavy bass outputs are large oscillating basins, but the effect of heavy bass is not very good. In order to meet the market demand for home theater sound, many companies are committed to research and development of large amplitude subwoofer, radial neodymium magnetic system is the most representative of the 18 inch subwoofer by controlling the thickness of the roof and the linear range of motion in the magnetic gap 2 inches long with 0.5 inch voice coil was greatly improved weight bass effect. In order to small speakers in a good bass effect, in the structure of paste in the side of the membrane suspension is similar, can let longer piston movement in the cylindrical frame in the diaphragm, such vibration basin before and after exercise up to 2cm, and then a small caliber loudspeaker can also have a good bass effect.
