  • Types of output interfaces of MEMS microphones

    The output signal of ECM (Electret Condenser Microphones) is almost all analog, most of which are single-ended. However, in contrast to MEMS Mic, there are two types of output interfaces: "Analog" and "Digital". Analog is also divided "Single-ended" and "Differential" outputs and digital output, which contains "PDM," "I2S," and "TDM" outputs. PDM occupies the most significant proportion.

  • The study of loudspeaker positions

    How can we balance ID appearances and acceptable sound performance? It’s always a critical task for the designer. The FEA (Finite Element Analysis) tool can be used to predict and analyze the influences of sound performance when the ID is initially locked down, and the optimized position of the loudspeaker can be chosen.

  • The Loudspeaker Developments for Laptop Acoustics

    A compact and as thin as possible form factor is the mainstream of designing current laptops. That causes traditional round-shape speakers, which are limited by the diameter (i.e., length and width), to be unable to satisfy state-of-the-art laptops. So, almost all loudspeakers designed for laptops have rectangular shapes to enlarge the vibrating area under a compact and limited space, and the longer, narrower, and thinner dimensions are the direction for future developments.

  • Compact High-Sound Pressure Buzzers for IoT & Alarm Systems

    Recently, the number of household IoT devices on the market has been gradually growing. In addition to the internet functions, etc., there is also a demand for a higher sound pressure level (SPL) and internal space requirements of the device. IoT devices usually need a modern design, so there must be a look for the small size of the component and meet the requirements of SPL.
