Double 12-inch active four-frequency-division linear array sound box

Abstract

The invention provides a double 12-inch active four-frequency-division linear array sound box. The linear array sound box comprises a box body, and a high-frequency unit, an intermediate-frequency unit, a medium-low-frequency unit and low-frequency units which are arranged in the box body. The box body comprises a mounting cavity and low-frequency cavities formed in the left side and the right side of the mounting cavity respectively; a curved clapboard is arranged in the middle of the mounting cavity; the mounting cavity is divided into a front first cavity and a rear second cavity which areindependent from each other by the curved-surface partition plate; the front end of the first cavity is sequentially provided with the medium-low frequency unit, the intermediate frequency unit, the high-frequency unit, the intermediate frequency unit and the medium-low frequency unit which are tightly connected from left to right, the high-frequency unit is arranged in the middle of the front endof the first cavity, and the intermediate-frequency unit and the high-frequency unit are symmetrically arranged on the two sides of the high-frequency unit respectively; the low-frequency units are arranged on the left side and the right side of the second cavity respectively, and the middle of the rear end of the second cavity is sunken inwards; and the intermediate-frequency unit is arranged inthe intermediate-frequency cavity. According to the invention, the low-frequency response is lower, and the sound pressure level is higher.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a dual 12-inch active four-way frequency-division linear array sound box. Background technique [0002] Most of the existing dual 12-inch line array speaker systems are three-way systems, which often require higher sound pressure levels and wider frequency responses in large-scale performances. However, the existing three-way line array systems, Since the 12-inch linear array speaker system needs to take into account both low frequency and low-medium frequency, it is also necessary to solve the problem that the sound wave at the back of the box cancels the energy, and the effect of the system is not optimal, and a lower low-frequency response cannot be obtained; moreover, Because the sound at the rear of the speaker of this dual 12-inch three-way system is too loud, it affects the sound reinforcement of actors and staff on the stage, and the sound effect is poor.

[0002] Most of the existing dual 12-inch line array speaker systems are three-way systems, which often require higher sound pressure levels and wider frequency responses in large-scale performances. However, the existing three-way line array systems, Since the 12-inch linear array speaker system needs to take into account the low frequency and low-medium frequency, it is also necessary to solve the problem that the sound wave at the back of the cabinet cancels the energy, so the system effect is not optimal, and a lower low-frequency response cannot be obtained; moreover, Because the sound at the rear of the speakers of this dual 12-inch three-way system is too loud, it affects the sound reinforcement of the actors and staff on the stage, and the sound effect is poor.
