High-Performance Acoustic Cavity Design for Loudspeakers

Kingstate has been improving and strengthening the capabilities of acoustic technology for designing loudspeakers. We always provide the best solutions for our customers' requirements with cost-effective products.  

It predicts the performance of diverse and customized box designs using the FEA (Finite Element Analysis) tool to build the simulation model that can effectively and efficiently solve the issues before making samples.

We are analyzing the performance of box design in 4-PI conditions and predicting the actual Sound Pressure Level (SPL) and Frequency Response, which can include the reflections from any object near the loudspeakers.

For most applications of small and micro speakers, the non-directional sound radiations,  Kingstate can find the SPL peak at Fb (tuning frequency) by importing the 3D drawing to the simulation model and suggesting if a specific Fb needs to be achieved.

Simulation model:

A down-firing smart speaker on a table with a cylinder closed-box design. (see chart 1)

Sound Pressure Level spreading at around 2.5KHz (Chart 1)

The SPL can be evaluated at a reference point with a defined distance (See Chart 2).
