Acoustic systems – housings of acoustic systems

Acoustic systems are complex devices that convert an electrical signal into sound waves that we hear. The housing of the speaker system is one of the most important elements of this device. In this article, we will consider what functions the speaker system body performs and what types of it there are.

Acoustic systems – body functions

The main function of the housing of the speaker system is to ensure the proper operation of the speakers inside it. The case has the following functions:

Speaker protection from damage. The case protects the speakers from external factors, such as shocks, scratches, etc. Also, the case reduces noise and vibrations that can occur inside the system.

Controlled sound diffusion. The case helps to control the diffusion of sound, that is, its dispersion in space. It can direct sound in a certain direction and create a more accurate soundstage.

Control of bass frequencies. The enclosure can amplify or dampen bass frequencies depending on its shape and material.

Management of resonances. The enclosure helps manage resonances within the system, reducing their impact on sound quality.

Types of housings of acoustic systems

There are many types of speaker enclosures, but the most common of them are the following:

Bass reflex. In this type of housing, the speaker is directed into a special hole on the rear wall of the housing, which allows the bass frequencies of the sound signal to exit the housing. Bass-reflex housings provide deep and powerful bass.

Closed. In this type of housing, the speaker is located inside a closed space that does not have any openings. Such housings provide clear sound and excellent controlled sound diffusion, but do not have such a powerful bass response as in bass reflex housings.

Double-walled. In this type of case, the speaker is located between two walls with different parameters. Double-walled housings provide good sound insulation and improved controlled sound diffusion.

Transmission linear. In this type of housing, the speaker is placed inside a long tube, which helps control resonances and improve sound quality.

Waveguide. In this type of housing, the speaker is located in a long tunnel, which allows you to control the sound reflection and improve the sound quality.

Lame type. This is a special type of housing for use in multi-channel audio systems. It allows you to place several speakers in one housing and control the angle of their location.

Speaker enclosures are an important element of a sound system and affect the quality of the sound we hear

According to your needs and sound system requirements, you can choose the enclosure that best suits your needs. For example, if you are looking for a speaker system for a large room or hall, then a bass reflex enclosure may be a better option for you as it provides powerful bass.

It is also important to consider the materials from which the body is made. Wood is one of the most popular materials for making speaker enclosures, as it provides good sound quality and durability. However, wooden cases can be quite heavy and require maintenance.

Other materials, such as plastic, metal or glass, can be used to make speaker enclosures. These materials are usually lighter and less durable, but can be more aesthetically pleasing and attractive.

In general, choosing a speaker enclosure depends on many factors, such as the size of the room, the type of music you listen to, and personal preference. The right enclosure can improve sound quality and provide the best music listening experience.
