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 and implement a greatly shortened design cycle. This is exactly how Waveburg Pro started
in 2001 as a boutique designer and manufacturer for custom-made pro audio loudspeakers.
Procedure of CAD drawings of cabinet:
1) Sketch of outlook
2) Draw line segment according to dimension obtained from previous simulation and testing
3) Transform to 3D solid cabinet
4) Match with other hardware, drivers, horn, etc.
5) Assembly of hardware and drivers
6) Transfer to 2D construction drawings
7) Rendering of 3D model for final products' images
With the use of the modern 3D modeling software, we easily estimate the cost of each product and obtain optimized dimensions, materials and tolerance.
CAD drawings provide accurate dimensions for both production and assembling.
After CAD cabinet is finished, the cabinet is precisly cut into pieces of Baltic birch plywood by software for production. Our advanced high speed CNC wood routing and machine operations are performed by experienced CNC machine specialists whose extensive wood materials and process knowledge ensure superior results.
Advantages of CNC production:
1) Accurate and 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 and assembling
of parts take place before we run extensive testing for every item by our QC specialists.
RESEARCH & DEVELOPMENT
At the very first step, we conducted a detailed marketing study and 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 for T/S parameters, thermal behavior and distortion for each driver that we include in our designs.
Every possible driver parameter and behavior is tested and observed at the driver's highest power driven stage. This helps the loudspeaker simulation and design phase, and ensures the performance and 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 and to provide multi-purpose solutions for integration and installation companies.
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 and T/S parameter at normal and 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
6) Velocity of air
7) Group delay
8) Far and 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 and 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 and cost of sample modeling of the finished
During the simulation and optimization process, usual loudspeaker problems are predicted
in such a way that the performance and reliability of each product is greatly improved.
