Laser Vibrometry
Scanning vibrometer measurements allow identification and characterization of dynamic material properties in loudspeakers and loudspeaker enclosures. Laser vibrometry provides unprecedented insight into the material and mechanical properties of any scanned surface and can lead to the clear identification of design and material anomalies.
By far it is the only way to confirm both material properties and the construction integrity of a enclosure and speaker system ensuring the absence of design flaws causing problems within the audio band and associated losses.
Design and ModelingDesign of complete acoustic architectures -•Ground up design of transducers for specific user applications•FEA (Comsol) based modeling of magnetics and all speaker components•Cone / Suspension / Spiders / Voice Coil / Steel Parts •Absolute optimization for all components•Assistance with selection and validation of “off the shelf” components in order increase speed to market•Complete modeling of acoustic systems using an available volume as a starting point.•Assistance in establishing performance base line and objectives vis-à-vis market and bom costs
Industrial and Mechanical Design We have years of experience in designing products for the professional and consumer market places. Our experience has been based primarily in the mechanical and acoustical design of speaker systems which has led to a wide body of knowledge in this particular area. We have industrial design capabilities or can openly work with you design concept team to achieve your aesthetic and performance objectives.
