OFM (Optical Finger Mouse)

Optical Finger Mouse(OFM) is a miniature form of the optical mouse used in PC. It is an optical input device operated by finger movement using the same technology as optical mouse. OFM are used in mobile phones, PC, remote controls, game devices and presentation devices.

▣ MEMS MIC

MEMS microphone is a subminiature microphone. Its high sound quality and its small size makes it suitable for smart phones. Using the Surface Mounting (SMT), full automation is possible, replacing the conventional manual processes.

▣ Digital ECM

Digital Electret Condenser Microphone (ECM) has a Pulse Density Modulation (PDM), it has a small size of 4.2X4.2X1.33mm.

An analog-to-digital converter (ADC) is built-in, therefore an exterior audio codec chip is unnecessary.
Surface Mounting Technology (SMT) is possible with Digital ECM. Digital MEMS and Digital PCM microphones are also under development.
