Linearity loudspeaker system high tone horn

Abstract

The invention discloses a linearity loudspeaker system high tone horn, comprising a horn main body, a throat port, an acoustic lens, a diffusion horn and a four-stage branch structure; the horn body is provided with a plurality of bolt holes; the horn body consists of two half-cavity structures which are symmetrical; and the integral horn is formed through passing a screw bolt into a screw hole to connect two symmetrical cavity structures into one integral horn. The delicately designed acoustic lens adopts the branch structure and an equivalent sonic path distance, converts the point acoustic source to a linearity acoustic source and adds the diffusion horn with a special design diffusion horn, which enables the loudspeaker system of the horn to partially satisfy the requirement of the linearity loudspeaker: the horizontal directivity is wide; the vertical directivity is very narrow and can be controlled; and when a plurality of sound box is combined and the mega bass is coupled and the high tones are not mutually interfered, which satisfies the usage requirement of the low distortion field. The horn consists of two half parts, which solves the feasibility of the manufacture technology, simplifies the die, and effectively controls the manufacture cost.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a tweeter horn for a linear speaker system. Background technique [0002] Loudspeaker horn is a key component commonly used in professional stage loudspeaker systems. It has appeared in the 1920s. Loudspeaker systems composed of high-pitched horns are often used for large-scale indoor and outdoor performance sound reinforcement: such as: dance halls, theaters, stadiums, sports fields , Movie theater sound reinforcement. Among them, the horn speaker does not have the energy storage problem of the cone speaker, can quickly and accurately absorb and release energy, has excellent damping characteristics and transient characteristics, and has high efficiency, so that the speaker system can have a larger sound pressure level. The transmission distance is long. At present, the linear speaker system has become the first choice for sound reinforcement of various large-scale acti...

Problems solved by technology

[0003] At present, there are several kinds of horns for linear speaker systems on the market, but their designs are either very complicated in structure and difficult to realize, or they are very difficult to process, high in manufacturing cost, and the consistency of the product cannot be controlled, or after loading the treble, the frequency The sound is not as expected, and the sense of hearing is very poor, which makes it difficult to control when it is practical
