Pressure Acoustic
COMSOL Multiphysics can build a method to quickly evaluate a receiver's performance in the pressure field of the IEC 318 standard. The IEC 318 standard is the type 1 artificial ear, defined as simulating the acoustic load of the human ear under no leakage conditions. Its frequency bandwidth of application is from 100Hz to 4KHz. The sound pressure level and impedance versus frequencies in the pressure field can be calculated in advance to see if requirements need to be met.

VoIP Phone
VoIP is a more advanced and reliably emerging technology for communication, replacing traditional communication, which is an irreversible trend. VoIP integrates the Internet and conventional communication technologies daily life. Kingstate also has powerful simulation technology to help customers analyze and improve their products. According to the application conditions and needs of customers' products, Kingstate can complete the design based on the speakers' selection and the speaker box's appearance.

Optimizing Leakages
Virtual reality attracts people’s attention again, and Metaverse has recently become a hot topic. Acoustic designs for a virtual reality device usually involve pressure or near-field acoustics. Here is an example of a near-field acoustic that reveals how to extend the bass for such a small speaker by designing the proper leakages in its enclosure.
