PRODUCTION
CAD CABINET design
Nowadays, computer aided design (CAD) software is widely used in many industries. With the aid of CAD loudspeaker design, it is possible to lower product development costs & implement a greatly shortened design cycle. This is exactly how Waveburg Pro started in 2001, as a boutique designer & manufacturer for custom-made pro audio loudspeakers.
Procedure of CAD drawings to cabinet:
1 - Sketch of the outlook of the final product.
2 - Draw the line segments in the cad program
according to the dimensions obtained from
previous simulation & testing.
3 - Transform a 2d design into a 3D model of a
solid cabinet.
4 - Match the 3d model with corresponding hardware
such as drivers, horn, etc and virtually assemble.
6 - Transfer new metrics to 2D construction drawings.
7 - Render the 3D model for final products' images.
With the use of the modern 3D modeling software, we easily estimate the cost of each product & obtain optimized dimensions, materials & tolerance.
CAD drawings provide accurate dimensions for both production & assembling.
RESEARCH & DEVELOPMENT
CNC PRODUCTION
After the CAD cabinet design is finished, pieces of baltic birch plywood are precisely cut into pieces by software for production. our advanced high speed CNC wood routing & machine operations are performed by experienced CNC machine specialists with extensive wood materials and process knowledge to ensure superior results.
Advantages of CNC production:
1 - Accurate and high quality production.
2 - Complex cabinet structure can be done.
3 - Precise engraving.
4 - Low and high volume production capacity.
5 - Cost effective by minimizing the waste of wood.
6 - Excellent production time management.
7 - Consistent production thru time.
8 - Easy modification for product improvement.
After the CNC cabinet manufacturing is done, water-based spray painting & assembly of parts take place before we run extensive testing for every item by our QC specialists.
PRE-ANALSYS
At the very first step, we conducted a detailed marketing study & survey for the needs of the pro audio industry as well as the desired requirements of loudspeaker systems, such as performance, specification, application, modularity, the look and price point, etc.
With advanced testing equipment, we obtain very precise results of the T/S parameters (Thermal behavior & distortion) for each driver, which we include in our designs.
Every possible driver parameter and behavior is tested & observed at the driver's highest power driven stage. This helps the loudspeaker simulation & design phase, & ensures the performance & reliability of the finished loudspeaker is up to today's market expectations.
From a large hardware database, we carefully choose the useful parts for each product, to maximize different application uses & to provide multi-purpose solutions for integration & installation companies.
SIMULATION
After we run the tests using the most advanced testing equipment, precise driver parameters are obtained with optimized driver behavior such as thermal effect on voice coil, excursion of motor & T/S parameter at normal & working stage. The enclosure simulation phase by software begins.
In this simulation process the following data is optimized:
1 - Cabinet shape and volume.
2 - Vents shape and dimension.
3 - Usable frequency range.
4 - Precise position for vents.
5 - Impedance.
6 - Velocity of air.
7 - Group delay.
8 - Far & near field performance.
During the whole procedure of simulation, not only the small signal (1m@1W) is simulated, but also at higher power consumption. That way we can optimize the loudspeaker performance & quality of sound at different levels, so that unpredictable problems caused by the non-linear behavior of the driver can be minimized. Before producing a sample of the loudspeaker, simulations are done to save time & cost of sample modeling of the finished cabinet during the simulation & optimization process. Usually, loudspeaker problems are predicted in such a way that the performance & reliability of each product is greatly improved.
