Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

In the era of intelligent interconnection of all things, audio technology is making a leap from "hearing sounds" to "understanding scenes". Shenzhen Mingjiada Electronics Co., LTD., as a globally renowned distributor of electronic components, directly supplies the full range of ST MEMS audio sensors, audio processors and audio amplifiers in stock, covering the entire chain demands from acoustic signal acquisition, intelligent processing to high-fidelity amplification, providing end-to-end audio solutions for consumer electronics, automotive cockpits and industrial Internet of Things.

STMicroelectronics is a world-leading provider of audio solutions, capable of offering:

A wide range of audio amplifier product portfolio.

2. Multiple packaging options, ranging from the powerful large MW to the smallest QFN, TQFP and CSP packages, can break all space limitations.

3. Highly reliable automotive-grade products.

A variety of ips, including innovative MEMS microphones, achieve outstanding sound effects in terminal applications. A variety of packaging options and chip technologies help save space and power consumption, thereby reducing costs.

Application scenarios: From consumer electronics to Industry 4.0

1. Smart terminal: Upgraded audio experience throughout the entire chain

TWS headphones: ST MEMS microphone (signal-to-noise ratio > 62dB) combined with a low-power processor, achieving transparency mode and active noise cancellation, with a 30% increase in battery life;

Intelligent cockpit: Multi-microphone array + automotive-grade processor (such as Stellar MCU), supporting zoned voice control and engine noise cancellation (AEC algorithm).

2. Industrial Internet of Things: Acoustic Diagnosis and Safety Monitoring

Predictive maintenance: MEMS microphones capture abnormal noises from devices, and feature frequencies (such as 20kHz harmonics in bearing failures) are extracted by edge processors, with an accuracy rate of over 95%.

Security intercom system: A 120dB high dynamic range microphone ensures distortion-free audio reception in explosive scenarios, and an amplifier drives a 100-meter long-distance broadcast.

3. Medical and health: High-precision acoustic analysis

The electronic stethoscope adopts ST ultra-low noise microphone (background noise < 25dBA), and the processor filters out 50Hz power frequency interference to assist in the AI diagnosis of lung sounds.

Relying on ST's original factory technical resources and global supply chain network, Mingjiada Electronics continuously empowers customers to build an intelligent acoustic closed loop of "perception - decision-making - output". Whether it is consumer electronics that pursue ultimate sound quality or industrial systems in harsh environments, ST audio solutions can provide a reliable foundation.
