When one thinks of a speaker, the first and foremost association may be the sound, however, did you ever wonder how that fragile technology is protected? That’s where the speaker grilles come. In addition, the speaker grilles are intended to perform two primary functions : prevent any parts lying internally, and ensure that sound does not pass through in a deformed manner. But how are they made? And how are these processes different? Let’s have a closer look at the speaker grills production methods.
Types of Speaker Grilles
There are a number of speaker grilles present those serve different functions due to their material used and design:
- Mesh Grilles : These are thin and flexible metal grilles used in professional sound systems.
- Foam Grilles : These are used in most household sound systems achieving high sound quality.
- Metal Grilles : They are used in high quality and commercial grade loudspeakers.
- Plastic Grilles: They are easy to use as a grill in cheaper speakers as they are cheap and lightweight plastic grills.
Methods to produce Speaker Grilles
Method 1: Stamping
Stamping is one of the most common types of production processes, needed mostly in the manufacture of metal speaker grills. In stamping, a flat sheet of metal die is placed in a press where it is sheared to the required configuration.
Benefits of Stamping :
- Adapts to mass production.
- Highly durable and economical for bulk quantity.
Applications:
Metal grills in the commercial speakers and the automotive speakers.
Method 2: Injection Molding
The most practical approach in the formation of plastic and foam speaker grilles is by injection molding. Plastic granules are heated in a machine until they become molten in order to be shaped in a machine.
Advantages:
- Makes it possible to come up with intricate objects.
- Use is appropriate for large scale manufacturing.
Disadvantages:
- Materials can be limited to mainly plastic and foam.
Method 3: CNC Machining
CNC machining is one of the forms of indent usage where a cutting equipment is driven therefore adopting computer technology except this time a program guides the machinery and all the cuts made and the shapes aimed are only directed on the screens. Mostly applies to the metal grille in high end speakers.
Why CNC?
- Accuracy and flexibility.
- Good for low volume production of standard and individual speaker hubs.
Method 4: Laser Cutting
This form of cutting involves the use of laser directed on materials at very high intensity hence leads to the exact cutting of required shapes of the materials. It has come into preference as it makes fine designs in metal grills.
Benefits of Laser Cutting:
- Great for intricate and complex designs.
- Suitable for both short runs and mass production.
Method 5: 3D Printing
In recent years, the use of 3D printing in the production of speaker grilles has come into being. This method entails creating the grille by ‘adding’ material in a layer by layer fashion mostly using plastics.
Advantages :Â
Ultimate design flexibility. Great for development and limited-scale production.
Disadvantages :
 At present constraints on the range of interment used and the speed of manufacture.
Method 6: Fabrication
Fabrication is the building or formation of a grille either manually or with the use of machines by bringing together pre-cut parts. It is convenient for custom or low quantity production.
Why Choose Fabrication?Â
- It enables customization.
- Appropriate for special or small quantity orders.
Materials Used in Speaker Grilles
The choice of the material influences the firmly attached part with respect to the performance and longevity of the attachment in the following ways.
Metal (steel, aluminum):
All metal grilles are sleek and highly durable but there is a problem, they interfere with the sound transparency.
Plastic(ABS,sop):
These materials are very light and cheap but are weak.
Foam and Fabric:
These are best in terms of sound transparency therefore more common in home audio systems.
Design and aesthetics
The design of a grille comes in handy when looking at how essential the item is performance wise, and its looks. High quality grilles do not only protect the speakers but improve sound distribution and add some aesthetics to the space.
Custom vs. Stock DesignsÂ
Custom designs will create a brand image and these usually come with an extra cost.
Durability Considerations
Durability depends largely on the material. Metal grilles last and resist damage. Plastic and foam grilles, on the other hand, tend to be weathered after a while.
Cost Differences
The method used to produce the grille has a direct relation with the price. Stamping and injection molding are more economical in mass production, while CNC machining and 3D printing are more applicable to small batches and individual orders.
Acoustic Performance
The way, how the grilles of the speaker are made, determines the sound heard from a speaker. For instance;
Open Grilles vs. Closed Grilles:
In terms of sound transformation, open grilles do better, but they do not protect as much.
Closed grilles are good for the purpose of sound, quite well in most instances but cannot protect as much.
