Description

Integrated horn structure capable of being installed by multiple treble simultaneously

Technical Field

The utility model relates to the field of wire array sound boxes, in particular to a horn structure of a wire array sound box.

Background

At present, in the line array loudspeaker box of the prior art, in order to obtain a larger sound pressure level, one or more high-pitched units with large size are mostly adopted, and the line array loudspeaker box is matched with corresponding waveguides and horns to form the line array loudspeaker box. However, the adoption of the large-size high-pitch unit can obtain higher sound pressure level, but the overall sound quality is general, the sense of sound particles is stronger, and the sound particles are not fine and rich enough, so that the sound quality and the sound effect of the whole sound field are greatly influenced.

In order to solve the problem that the physical characteristics of the large-size high-pitched unit influence the tone quality, the small-size high-pitched unit can be adopted to replace the large-size high-pitched unit, the vibrating diaphragm of the small-size high-pitched unit is small in size and light in weight, the large-size high-pitched unit can vibrate more rapidly, and the transient state is correspondingly better than that of the large-size vibrating diaphragm, so that the small-size vibrating diaphragm can express high-pitched details more accurately. However, since the small-sized tweeter unit itself has a low sound pressure level, when a desired sound pressure level is to be obtained, a combination of several small-sized tweeter units, the number of which is much larger than the installation space of the tweeter unit, must be used to obtain a sound pressure level that relatively meets the application requirements. In this way, the wire array type speaker box with the same specification and the same size is very difficult to install the small-sized tweeter units and the corresponding waveguides and horns.

In the current stage, the waveguides and the horns are arranged one by one and fixedly arranged on the loudspeaker box shell, and the waveguides and the horns are mutually spliced and abutted together. The small-sized high-pitch units are correspondingly arranged on the horn one by one, or the small-sized high-pitch units are correspondingly arranged on the horn, and then the waveguides are correspondingly arranged on the sound box body with the horn. The wire array type sound box formed by the method has the advantages that the adjacent horns are not effectively fixed due to the limited space of the box body (note: generally, the fixed installation of one horn is at least fixed by three to four screws). When the loudspeaker box works, each horn can generate stronger resonance due to the sounding of the bass unit of the linear array loudspeaker box, so that the adjacent horns have the defects of mutual friction, impact, resonance and the like, and the sounding quality of the loudspeaker box can be disturbed and influenced over time, and the service life of the horns can be also influenced.

Therefore, in order to solve the problem that a plurality of small-sized tweeters can be smoothly installed in a wire array type sound box and form an effective wire array mode, how to design the structures of the waveguides and the horns of the small-sized tweeters becomes an important and troublesome technical problem. The utility model aims to solve the technical problem.
