Technical Field

The invention relates to the field of sound wave horns, in particular to a novel reflective directional sound wave horn.

Background

The horn loudspeaker is a terminal device of public sound amplifying systems such as various early warning and alarm systems. The performance of the horn, such as conversion efficiency, frequency characteristics, directivity, etc., has a significant influence on the effectiveness and investment cost of the above described public address system. The horn and speaker combination can only function.

A horn speaker widely used in the prior art radiates sound waves in one direction from one driving unit to the next horn.

Because the vibrating diaphragm in the driving unit is in a bidirectional vibration state under the driving of the electrodynamic force, the unidirectional radiation sound wave only utilizes about 50% of sound energy excited by the vibration of the sound diaphragm, and the reverse sound energy causes waste and is converted into useless heat energy and mechanical energy.

The technical solution of the present invention is further described in detail with reference to the accompanying drawings and embodiments.

As shown in FIGS. 1-8, the reflection type directional acoustic wave horn of the present invention uses modified plastic ABS + PC material, so that the horn has improved chemical resistance, thermal stability, toughness and impact strength, and good rigidity and processability. And the overall weight of the horn can be reduced.

The horn adopts a bidirectional magnetic circuit system and a vibration system, so that the sound power and the frequency characteristics of the radiation of the horn loudspeaker in the forward direction and the reverse direction are basically the same, and the useless energy and the heat energy release in the driving unit are reduced. Meanwhile, the thermal reliability of the loudspeaker is improved, and the probability of damage of the voice coil is reduced.

The forward sound wave directly radiates, and the backward sound wave radiates to the horn rear wall and then radiates to the horn the place ahead after the reflection, so the total sound wave emission efficiency of the horn obtains very big promotion, and the design of horn arm angle has promoted the directive property of horn speaker simultaneously.

The transducer upper cover component 9, the sounding group 2 is bonded on the transducer sound collecting disc by the voice coil and the sound film; the magnet assembly 1 consists of a neodymium magnet, a magnet upper cover and a magnetic circuit seat, and the sounding group 2 is arranged on the magnet assembly 1; the reflecting cone component 8 consists of a reflecting cone and a reflecting cone seat, and the reflecting cone component 8 is arranged on the sounding group 2; another group of magnet assemblies 1 are arranged above the reflecting cone assembly 8; a transducer upper cover assembly 9 is mounted above the magnet assembly 1, and a transducer lower cover assembly is mounted below the magnet assembly 1, respectively.
