Advanced Piezo Disks Driving Innovation with Limitless Applications
Piezo disks are widely used in daily life as key components in numerous technological products. These devices possess unique properties: when deformed by an external force, they generate an electrical signal; conversely, when a voltage is applied, they undergo deformation. Thanks to this bidirectional physical characteristic, the Piezo disk can serve both as a sensor—detecting variations in various physical quantities—and as a sound-producing element, converting electrical energy mechanical energy to perform multiple functions.

Applications of Virtual Fencing and Trackers
In the livestock industry, managing the grazing locations of animals like cattle and sheep while ensuring environmental sustainability is crucial for farmers. Traditional methods often involve erecting physical barriers such as wooden or electric shock fences, but these can be difficult to install over large areas and raise ethical concerns. Consequently, some farmers have adopted electronic fence systems, which alert them with a mild electric shock or warning message if animals attempt to leave the designated area. However, this approach adds to the labor and resource demands on farmers.

Introduction to IEC60601-1-8 Regulations and Medical Product Applications
The purpose of the IEC60601-1-8 standard is to define the safety and performance requirements for audible or visual alarm systems used in medical electrical equipment. This article only uses the sound alarm as the main description. This standard specifies minimum sound pressure limits and duration for sirens. It is required that the alarm volume be heard in a noisy environment, and the alarm time must be long enough to attract the attention of medical personnel to ensure that correct responses and judgments can be made promptly without causing confusion, misjudgment, or disturbing the patient. Suffer. Therefore, if the alarms in medical equipment can comply with this standard, it will be a guarantee for the medical staff and patients in the hospital.

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.
