Custom speakers Solving sound diffraction: What causes sound diffraction?

is the speaker box itself, due to the sound of the unit is not only in front of the energy, and the expansion of the energy in all directions, so the box next to the edges and corners of the easy to cause the high-pitch diffraction, diffraction phenomenon is serious, may produce interference, thus affecting the high frequency of the energy sense, reduce the sound of the image force, As for how to reduce sound diffraction, this is one of the biggest headaches for many loudspeaker manufacturers, and they have tried every means to solve this problem.

A simple solution is to buy a thin piece of foam or flannelette, cut it into small pieces, and stick it around the tweeter unit to improve it, or more dramatically, to insert the whole speaker in the center of a large piece of foam.

Although this approach to improve the sound is absolutely immediate, but its visual effect is extremely poor, the ideal method is to expand the front barrier as far as possible to reduce sound diffraction, and embedded is to use a wide wall as a front barrier to solve the problem of sound diffraction.

Solve box vibration: as we all know, box vibration is the biggest enemy of the speaker, this is because the vibration of the box will make the speaker sound dye, affect the faithful restoration of sound, how to make the box can be more solid and not affected by vibration? The traditional home loudspeaker is to use a variety of reinforcement measures in the box.

For example, wood skeleton support, plus internal partitions and so on, are a good way to make the box more rigid, and some speakers use metal as a box, hoping to use the weight of metal to inhibit the vibration of the box.

For embedded loudspeaker, the wall in addition to its front barrier is also equivalent to its box, therefore, as long as the wall in your home has enough strength and thickness, theoretically, this can easily solve the "box" vibration problem, so that embedded loudspeaker issued a more real and more accurate sound
