Second, characteristics: its sound quality has the characteristics of extremely high propagation sensitivity, wide directivity, uniform sound field distribution, clearer sound quality, good transient response and strong sense of depth; Due to the use of the latest high-tech materials, the speaker has the characteristics of strong light sensitivity, pleasant tone, portability, heat resistance, dustproof, waterproof, intelligent, power saving, environmental protection and space saving. Exquisite decorative mural speakers can bring you both visual and auditory enjoyment at the same time, so that you can realize "watching a painting and listening to a song" through the perfect combination of time and space, and you can hear harmonious and powerful sounds anywhere in the room, that is, "no distance, all space". Compared with the traditional speakers, the ultra-thin flat wall-mounted speakers are more perfect. Based on the sound generation principle, the audience can hear the sound of "dull near, clear far away and constant sound source". It is a revolutionary innovation in the field of decorative audio in the world.
Flat speakers are different from cone speakers, as the name implies: the diaphragm of flat speakers is flat. As early as 1970s, the principle of flat panel speaker was born, which was formed according to the bending wave theory of Dr. Jose W. Manger in 1978 and the Mangel sound converter he invented. There are two groups of vibrating voice coils under the diaphragm of a flat speaker. The vibrating surface of a flat speaker moves back and forth in a cavity similar to a "cylinder" to convert electric energy into acoustic energy. At the edge of the "cylinder", there are damping plates and vent holes that move back and forth. We can call the vibrating basin of a flat speaker a "pond". The generation of sound wave energy is like throwing a stone on a calm water surface, and sound waves spread outward in concentric circles from the center of the vibrating surface. Based on this principle, the restored sound quality of flat-panel speakers is excellent, which has the advantages of wide frequency range, small distortion and good transient response. In foreign countries, flat-panel speakers are also used in professional fields, such as the flat-panel speakers of AUDIO PHYSIC Company in Germany. However, compared with other speakers, it is still less, probably because the manufacturing technology is difficult and expensive, so it is not popular!
