Why are so many people in love with wall-mounted speakers now?

Wall-mounted sound structure

1. Driver

It is equivalent to a heart of the flat speaker. The design point of the driver is that its effective stroke is very small, generally no more than 2m/m2; secondly, the voice coil part should not be too heavy, otherwise there will be serious distortion in the high frequency part. 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 performance.

2. Vibration pine

It is just like the human vocal cords, which plays a decisive role in the tone color, 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)

3. Suspension system

The vibration principle of flat-panel speakers is completely different from that of general traditional speakers. Ordinary traditional speakers use a piston-type vibration method, while the vibration of a flat-panel speaker adopts a 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 may even There are more than two dozen points.

4. Backplane

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 flat-panel speakers vibrate in waves. 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 different positions of the listener. sound effect

Three, wall-mounted audio installation method

1. The wall-mounted wall should be a load-bearing wall

When choosing the location of the wall-mounted audio system, you should know the wall structure of the house in advance. It must be concrete, solid brick or load-bearing wall to meet the requirements for installing the wall-mounted audio system. Of course, this also needs to consider the load-bearing capacity. The background wall is also of αk.

2. Installation environment requirements

It cannot be used in a humid environment, because the speaker is basically not waterproof, and the installation location is too humid to directly damage the sound, and the environment with strong heat and strong light is not suitable.

3. Consider signal interference factors when installing wall-mounted speakers

Avoid the impact of strong electricity and strong electromagnetic field objects on the sound effect of wall hangings. Generally, some electrical appliances, such as radios, induction cookers, microwave ovens, etc., will affect the effect of speakers, so it is best to keep them as far away as possible.
