Description

A PRO speaker horn

Technical Field

The utility model relates to the technical field of speaker horns, in particular to a PRO speaker horn.

Background Art

The horn is a sound amplification product, which is usually used in sound amplification equipment such as speakers and horns. It includes a sound source back end and a sound amplification front end. The sound amplification front end is a conical horn mouth. When working, the horn concentrates the sound waves through the conical horn mouth, which can make the sound travel farther. The horn in the prior art has unsatisfactory sound quality when it diffuses outward. For this reason, we have proposed a PRO speaker horn.

Utility Model Content

The utility model aims to solve the shortcomings in the prior art and proposes a PRO speaker horn.

In order to achieve the above purpose, the utility model adopts the following technical solutions:

A PRO speaker horn comprises a horn body, the horn body comprises a base, a horn tube is fixedly sleeved inside the base, a rectangular outer edge is integrally arranged on the top of the outer ring of the horn tube, four reinforcing ribs are fixedly connected to the top of the base in an annular shape on the outer side of the horn tube, and four tweeter holes are opened in an annular shape on the top of the base.

Preferably, four mounting holes are provided at the top of the rectangular outer edge.

Preferably, any cross-sectional shape of the horn body is a rectangle, and the horizontal generatrix and the vertical generatrix of the horn body are both segmented involutes.

Preferably, the total length of the horn body is 160 mm, the width is 131 mm, and the height is 61 mm.

Preferably, the left-right HSI arc of the horn tube is 90 degrees, and the front-back HSI arc is 60 degrees.

Preferably, the inner diameter of the bottom of the horn tube is ф30.48 mm.

Compared with the existing technology, the beneficial effects of the utility model are:

By setting the horn tube's left and right HSI arc to 90 degrees, the front and rear HSI arc to 60 degrees, and the inner diameter of the sound hole at the bottom to ф30.48, the sound quality is made open, mellow, pleasant, transparent and bright. In addition, the setting of the treble hole can be used to install a tweeter, thereby expanding the sound amplification range, with a wide frequency response range and high-efficiency performance;

By setting the total length of the horn body to 160mm, the width to 131mm, and the height to 61mm, its overall size is compact, suitable for using a column speaker for conference rooms;

The horn body disclosed in the utility model emits a broad, mellow, pleasant and transparent sound, and at the same time has a larger sound amplification range, good language clarity, soft sound and wider sound coverage, and has a wide frequency response range and high-efficiency performance to meet usage requirements.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Referring to Fig. 1-4, a PRO speaker horn includes a horn body, wherein any cross-sectional shape of the horn body is a rectangle, the horizontal generatrix and the vertical generatrix of the horn body are segmented involutes, the total length of the horn body is 160 mm, the width is 131 mm, and the height is 61 mm. The horn body includes a base 1, and a horn tube 3 is fixedly sleeved in the base 1, wherein the left and right HSI arc of the horn tube 3 is 90 degrees, the front and rear HSI arc is 60 degrees, and the bottom inner diameter of the horn tube 3 is ф30.48 mm;

A rectangular outer edge 4 is integrally provided on the top of the outer ring of the horn tube 3, wherein four mounting holes 5 are provided on the top of the rectangular outer edge 4, and four reinforcing ribs 6 fixedly installed on the top of the base 1 are fixedly connected to the outer side of the horn tube 3 in a ring shape, and four tweeter holes 2 are provided in a ring shape on the top of the base 1. The horn body disclosed in the utility model emits a sound that is open, mellow, pleasant, transparent and bright. At the same time, it has a larger sound amplification range, good language clarity, soft sound and wider sound coverage, and has a wide frequency response range and high-efficiency performance to meet the use requirements.

Working principle: The whole device can be installed at the sound-generating position through four mounting holes 5. By setting the left and right HSI arc of the horn tube 3 to 90 degrees and the front and rear HSI arc to 60 degrees, the sound quality of the sound produced is open, mellow, pleasant and transparent. In addition, with the setting of the tweeter hole 2, a tweeter can be installed, thereby making the sound amplification range larger, with a wide frequency response range and high-efficiency performance;

The provision of the reinforcing ribs 6 can improve the strength of the horn tube 3, and the volume of the entire horn body is small, which is suitable for use in a conference room.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
