[0002] A passive line array speaker is a professional audio device composed of an array structure formed by arranging multiple speaker units. Different from an active line array speaker, a passive line array speaker does not have a built-in power amplifier and requires an external power amplifier device to drive it. According to a three-way coaxial line array speaker disclosed in the utility model with the patent authorization announcement number CN219960762U, which includes a box body, as well as a mounting plate, a three-way coaxial unit and at least four passive radiators arranged in the box body. The mounting plate divides the space inside the box body into a front cavity and a rear cavity. The three-way coaxial unit and the four passive radiators are mounted on the mounting plate, and the four passive radiators are symmetrically arranged with the three-way coaxial unit as the center. The passive radiator is adapted to passively sound under the drive of the air driven by the three-way coaxial unit. The sound output ends of the passive radiator and the three-way coaxial unit are both arranged in the front cavity. When hanging a passive line array speaker, high-altitude work is required, which is not convenient during installation. Content of the Utility Model
