Description

Linear array sound box with high-pitch horn combination

Technical Field

The invention relates to a sound box, in particular to a linear array sound box with a high-pitch horn combination.

Background

Because the existing sound box almost adopts the design mode of multi-unit frequency division band playback, the full-band music signals sent by the power amplifier are divided into high pitch and low pitch output or high pitch, medium pitch and low pitch output according to the requirements through the frequency divider, and then the full-band music signals can be connected with the corresponding loudspeaker units. If the full band signal is fed directly to the high, mid and low frequency units without distribution, the "unwanted signal" that is outside the frequency response range of the units will adversely affect the signal recovery in the normal band and may even damage the high and mid frequency units. If the high pitch horn is used in a sound box, the high pitch horn is inevitably matched with a low pitch horn or a middle pitch horn and is used in a work division and cooperation mode, at the moment, the high pitch only plays a high pitch function, and the middle pitch sensitivity in the high pitch horn is very low, and the curve is very poor, so that the high pitch horn cannot be matched with the middle pitch horn or the low pitch horn. Moreover, the frequency dividing point is determined for the design of each sound box according to the characteristics of the high pitch loudspeaker, the middle pitch loudspeaker and the low pitch loudspeaker in the sound box, and the middle pitch loudspeaker disperses the energy of the middle pitch due to frequency diffraction, so that the sound pressure level is very low. If only a small cone full-frequency loudspeaker is used as the linear array loudspeaker, the sound pressure level can be greatly reduced, the diameter and the length of the cone loudspeaker can be influenced by the process and can not be shortened, and the problem of coupling cannot be solved. Therefore, there is a need for improvements in the prior art to avoid the disadvantages of the prior art.
