The acoustics engineering team at Korea Omyang selected the Virtual.Lab solution for its powerful capabilities to accurately predict the generated sound of its speaker system designs.
Korea Omyang Corporation has LMS Virtual.Lab Acoustics to optimise the acoustic performance of speaker systems which are built in passenger cars for in-vehicle entertainment.
Acoustic simulation is used to support the design of speaker systems at the Korean manufacturer and to analyse the mounting strategy in the vehicle interior to obtain an optimal sound quality.
The acoustics engineering team at Korea Omyang selected the Virtual.Lab solution for its powerful capabilities to accurately predict the generated sound of its speaker system designs, taking into account the vehicle interior.
Korea Omyang Corporation specialises in the development and manufacturing of speakers for cars, TV sets, phones, Hi-Fi and other audio/visual systems.
Its primary customers include companies like Lucent, Toshiba, Sony, Schneider in the consumer electronics field, and automotive manufactures like Hyundai, Kia, GM Daewoo and GM Holden.
In the automotive field, Korea Omyang faces the stringent challenge of developing a competitive speaker package which is adapted to the new vehicle model or interior configuration.
The company selected LMS Virtual.Lab Acoustics to increase its development speed and to efficiently optimise the shape, packaging, positioning and mounting of the speakers for optimal sound.
In a first step, LMS Virtual.Lab Acoustics is used to optimise the sound of the individual speaker elements and to optimise the accuracy of the speaker simulation models before they are mounted in a vehicle interior configuration.
In a second step, Omyang engineers investigate and optimise the vibration and sound levels of the individual speakers mounted in the vehicle interior.
In doing so, they face very stringent requirements from the OEM in terms of allowed space and position, overall weight, cost and obviously the required sound quality.
"The deployment of LMS Virtual.Lab Acoustics allows us to carefully balance all these requirements from the early development stage onwards".
"The LMS solution gives us an accurate prediction of the acoustic performance of a specific design option, and allows us to trace back the root cause of sound or vibration problems", commented Kab Jae, Yoo, Senior Engineer at Korea Omyang Corporation.
The company also valued LMS Virtual.Lab for its tight integration with Catia V5 and its facilities to exchange models with automotive OEMs.
"The smooth exchange with our internal or our customer's design team saves a lot of modelling time and strongly facilitates the communication process", commented Kab Jae, Yoo.
"The tight integration of all simulation process steps in LMS Virtual.Lab delivers an additional efficiency gain, and allow us to deliver the accurate insight which is required to make critical design decisions".
