Problems solved by technology

The horns used in high-frequency drivers and intermediate frequency drivers on the market generally do not have phase plugs, or only use simple bullet phase plugs, and the bullet phase plugs only have a certain positive effect on the circumferentially uniform "eight"-shaped horn shells. When the horn shell is of other shapes, it is far from meeting the needs
[0006] In addition, in the prior art, the upper limit frequency of the horn connected to the high-frequency driver is only 16.5kHz, and there is still a certain distance from the 20kHz upper limit frequency requirement for high-quality requirements; the lower limit frequency of the horn connected to the high-frequency driver cannot meet the needs

Embodiment Construction

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] A loudspeaker horn, comprising at least two horn units connected to each other, each horn unit comprising a horn-shaped casing 20, the large end of the casing 20 is a face plate 21, and the casing 20 includes a throat pipe arranged at its small end, Several manifolds are fixed in the throat, and the manifolds communicate with the two ports of the throat. By setting the manifold, the present invention can greatly increase the upper limit frequency of the horn.

[0038] Preferably, there are two horn units, which are a high-frequency horn 9 and an intermediate-frequency horn 6 fixed on one side of the high-frequency horn 9 . The number of manifolds provided in the high frequency horn may be twelve, and the number of manifolds provided in the intermediate frequency horn may also be twelve. By setting up the manifold, the upper limit frequency o...

Abstract

The invention relates to the technical field of audio products, in particular to a speaker horn. The loudspeaker horn includes at least two horn units connected to each other, each horn unit includes a horn-shaped casing, the large end of the casing is a face plate, the casing includes a throat arranged at the small end, and the throat is fixed inside Several manifolds are provided which communicate with the two ports of the throat. The present invention greatly improves the upper limit frequency of the horn.

Description

technical field [0001] The invention relates to the technical field of audio products, in particular to a speaker horn. Background technique [0002] In the traditional three-way speaker system design, a high-frequency driver, a mid-range driver and a low-frequency unit are often used to form a three-way full-range speaker, and the high-frequency driver and mid-range driver are equipped with a split or connected The mid- and high-frequency horns of the body are used to cooperate with the low-frequency unit to reach the sound waves reproduced by the high-frequency driver and the mid-frequency driver and project them into the use space. [0003] According to the acoustic theory, sound waves have the phenomenon of sound wave reflection and sound wave interference. When the high-frequency driver and mid-frequency driver diaphragms move forward and backward as pistons, the resulting sound waves radiate outward through the horn throat to form sound. However, not all sound waves s...
