7. 1 Height of sound from the ground
7. 1 Sound is 2-4m away from the ground. 2-3 meters away from the listener, 2-3 meters left and right of the trunk, and about 1 meter away from the listener.

You must follow the requirements in the picture, that is, there can be no furniture in the listening room, the distance between the speaker and the wall is the same, the sound reflection effect is the same, and the audio-visual positioning is accurate to achieve the real surround sound effect.

If you like listening to music at high volume, you must also use sound-absorbing materials, lay carpets on the ground and hang decorative tapestries on the wall, so that the sound will be much purer, the sound layering will be much better, and the high notes will not be scattered.

Principle of horn sounding:

A very important piece of equipment in a sound system is a sound box, which generally consists of a speaker unit and a box. The speaker unit is used as a sound generating part, and the box is used as a supplement to the speaker unit to correct the sound. The sound generation principle of the horn unit is the conversion from electric energy to sound.

When different electric energy is transmitted to the coil, the energy generated by the coil interacts with the magnetic field of the magnet to make the paper tray vibrate. Because the electronic energy changes at any time, the coil of the horn will move forward or backward, so the paper tray of the horn will also move with it, which changes the density of air and produces sound.
