Horn body

horn-shaped, usually made of plastic, metal, wood and other materials. The shape and size of the horn varies according to the desired audio frequency and application scenario.
 

Driver unit

A loudspeaker unit connected to the horn and responsible for generating sound. The sound is transmitted through the drive unit into the horn, which is then extended and directed through the horn structure.
 

The loudspeaker horn helps the sound travel better. It makes the sound louder and clearer, especially in big places like stadiums and concerts. The horn helps focus the sound so it can go farther. It also reduces noise and echoes, which makes the sound clearer, especially the high-pitched sounds. Plus, the special bass horn makes the low sounds stronger, giving more powerful bass.

ow Horn Loudspeakers Affect the Propagation and Quality of Sound

I'm sure you're also curious as to why speaker horns amplify sound and spread it farther.

1. Propagation Distance: Speaker horns help sound maintain sufficient energy and clarity over longer distances by increasing the efficiency of the match between the air and the drive units. In speakers without horns, the sound would decay rapidly with distance.

2. Sound Diffusion: The shape and size of the horn determines how sound waves are diffused. By adjusting the angle and length of the horn, the angle and range of sound extension can be changed. For example, a wide-angle horn is suitable for occasions requiring wide diffusion, while a narrow-angle horn is suitable for occasions where the volume is concentrated and the sound is focused. In this way, the speaker horn can accurately control the coverage of the sound to avoid unnecessary noise interference.

3. Improvement of sound quality:The speaker horn not only makes the sound louder and travel farther, but also makes the sound clearer by reducing noise and improving sound waves. It is especially good at making high-pitched sounds clearer and purer by reducing distortion.

4.Efficiency Improvement: Conventional speakers usually require more power to drive loud volumes, while speaker horns, by improving efficiency, enable speakers to produce more volume with relatively low power, which is very beneficial to saving energy and extending equipment life.

Types of horn speakers

Conical Horn

The Conical Horn is the most common type and has an even extension angle. Its design is similar to a conical shape, with audio conducted from a narrow port to a wide port.

Pros:

♦ Simple and easy to manufacture, relatively low cost.
♦ Provides good dispersion for midrange and high frequency sounds.
♦ Commonly used in small to medium sized sound systems.

Cons:

♦ Limited range of extension, suitable for venues where great coverage is not required.
♦ May not be as good as other types of horns in low frequency response.

Applicable:

♦ Suitable for home theaters, small public address and medium-sized performance venues.

Rectangular Horn

Rectangular horns are rectangular in shape and usually have a wider extension angle. This type of horn is used where there is a need to control the range of sound propagation.

Pros:

♦ Wider extended range, covering more area.
♦ More balanced sound quality, suitable for low and medium frequency sound propagation.
♦ Highly efficient and suitable for large sound systems.

Cons:

♦ Relatively complex structure, requires more space for installation.
♦ May cause distortion in some frequency bands, especially in the high frequency part.

Applicable:

♦ Suitable for large venues, such as stadiums, large concerts, conference rooms.

Elliptical Horn

The Elliptical Horn is designed in the shape of an ellipse for applications that require special control over the angle of sound extension.

Pros:

♦ Provides more directional sound propagation and can avoid unwanted sound scattering.
♦ Commonly used in medium to high frequency applications to ensure clear sound focus.

Cons:

♦ Not suitable for low-frequency sound extension; low-frequency response may be weak.
♦ More complex to design and manufacture.

Applicable:

♦ Suitable for places that require precise control of sound direction, such as theaters, conference centers and high-end sound systems.
