Home theater wall speaker is composed of audio source input device, signal amplifier (power amplifier) and wall-mounted speakers, which is a complete set of sound system.
What is the role of a driver in a Home theater wall speaker?
What are the structures in a Home theater wall speaker?
What is the difference between Home theater wall speakers and ceiling speakers?
The drive is the heart of a Home theater wall speaker. The design point of the driver is that its effective stroke is very small, generally not more than 2m/m2; secondly, the voice coil part should not be too heavy, otherwise there will be serious distortion. The design requires light weight, small volume and large magnetic force. Based on the above factors, we use high magnetic materials, generally the magnetic flux density must be greater than 10,000 Gauss, in order to have better expressiveness. Sometimes in order to increase the output, two or four drivers are used to increase the output sound pressure, and a better frequency response curve can be obtained by using multiple drivers. The number of drivers used depends on the size of the vibration plate area. And the weight, the use of high-tech smart exciters of Tovec ensures the safe use of the Home theater wall speaker while ensuring the high-quality sound quality of the product.
1. Vibration plate: Just like the vocal cords of humans, it plays a decisive role in the timbre, the size of the sound, and the flatness of the sound, so it plays an important role in the flat-panel speaker after the driver (Exciter).
2. Suspension system: The vibration principle of the Home theater wall speaker is completely different from that of the general traditional speakers. The general traditional speaker adopts the piston-type vibration method; while the vibration of the flat-panel speaker adopts the random vibration method, so its lowest resonance frequency is not only one point, but more than a dozen points. A well-designed flat-panel speaker, There are even twenty points. And its driving point is not in the center, because the center does not get the maximum sound pressure and the smoothest frequency response curve, but in the best position of the node vibration, plus four suspensions in a 1:9 ratio Suspension points form a reasonable suspension system.
3. Back plate: The design of the back shell must take into account the opening on the back shell to increase the diffraction of sound waves, because the Home theater wall speaker is a wave-type vibration. The same sound pressure will be generated on the back of it (only the phase is different), so there must be a window to increase the sound radiation, so that it has better directivity and is not affected by the difference of the listener's position. Sound effects, TOMIC fully considers this point in the product design, and makes the sound quality in the leading position in the industry.
The sound reinforcement of the ceiling speakers is relatively uniform (the coverage angle is about 120 degrees). The Home theater wall speakers have strong directivity (directivity), and the sound is slightly larger than that of the ceiling speakers. If the area of the factory is relatively large, and the middle position is the work area Use ceiling speakers, or wall-mounted speakers if the four sides of the home are work areas.
Davecl was founded in 2003, and we focused on HIFI stereo system and also powered speakers.
Our target is to give our customers the best sound quality at the best price possible.
For the design, Both engineered design and estethic design. We want the design to be modern, simple and sophisticated and powerful with great sound.
