What is the working principle of the flat panel speaker?

I. Principle: It is through the sound plate in the sound bending wave and sound, the core part of the high-tech intelligent exciter technology exclusive possession, its emergence has completely changed more than 80 years of history of the traditional speaker technology, from the principle of sound to the appearance of the structure is different from the traditional speakers.

Two, features: its sound quality has a very high propagation sensitivity, wide directivity, sound field distribution uniformity, sound quality is clearer, transient response is good, the depth of the strong sense of character; due to the use of the latest high-tech materials, making the speaker picture light sense of the strong, pleasing hue, lightweight and heat-resistant, dust-proof, waterproof, intelligent, power-saving, environmentally friendly, space-saving and other features. Exquisite decorative mural speakers, can bring you both visual and auditory double enjoyment, so that the perfect combination of time and space so that you "see a picture, listen to a song", in any position indoors can hear the harmonious and powerful sound, that is: "no distance, all space! ", compared with the traditional speakers ultra-thin flat wall-mounted speakers are more perfect, based on the principle of sound so that the admirer sounds "near not vibrate the ear, far away is very clear, the source of the sound does not come from where, the music is everywhere". It is a revolutionary innovation in the world of decoration and sound.

Flat panel speakers and cone speakers are different, as the name suggests: flat panel speaker diaphragm is flat. As early as the 1970s, the principle of the flat loudspeaker was already born, based on Dr -Jose W - manger (Joseph W - manger) in 1978, the bending wave (Bending wave) theory and his invention of the Manger acoustic transformation device (Manger Schallwandler) formation. In the flat speaker diaphragm below the general two groups of vibration voice coil, flat vibration surface in the cavity similar to the "cylinder" back and forth movement of electrical energy into acoustic energy, in the "cylinder" edge and back and forth movement of the damping plate and the ventilation holes, we can put the Flat-panel speaker vibration basin is likened to a "pond", the generation of acoustic energy as in the calm water surface throwing stones, sound waves from the center of the flat-panel vibration surface in concentric circles to the outside, based on this principle, flat-panel speaker is a true coaxial **** point speakers. Flat-panel speakers restore sound quality is excellent, with a wide frequency range, small distortion, good transient response and other advantages. In foreign countries, flat-panel speakers are also used in professional fields, such as the German AUDIO PHYSIC company's flat-panel speakers. But relative to other speakers is still less, perhaps due to the difficulty of manufacturing technology, expensive, not popularized!
