B[Auto core manufacturer NXP issues another price adjustment letter, raising prices starting from January 2027] On November 2, reporters learned from the industry chain that due to the rising costs of raw materials, energy, manpower, logistics and upstream suppliers, NXP (NXP) has sent a letter to dealers planning to increase prices for some distribution and direct supply product lines. The new regulations will take effect on January 1, 2027. Some dealers told reporters that it is recommended that projects with confirmed demand place orders in advance to lock in costs and avoid the impact of price adjustments. Little Whale's Note: NXP is a Dutch semiconductor manufacturer and the world's leading automotive chip manufacturer. It specializes in vehicle processors, MCUs, and wireless connection chips, and has deployed Bluetooth and Star Flash multi-mode short-range communication solutions. This is its third round of price adjustment notices in 2026. (Blue Whale News) B[Smart Glasses Acoustic Performance Test Specifications Will Be Officially Implemented from October 2] On September 30, reporters learned from the State Administration for Market Regulation today that the national metrology technical specification "Smart Glasses Acoustic Performance Test Specifications" will be officially implemented from October 2, which will delineate a unified technical scale for the acoustic performance testing of smart glasses. With the rapid development of artificial intelligence, smart glasses are used in daily life and office scenes, becoming an important carrier of human-computer interaction. They connect to mobile phones through Bluetooth to realize core functions such as calls, audio playback, and voice interaction. The acoustic performance is directly related to the user experience and hearing health. The "Specification" directly addresses the pain points of the industry and responds to the consumer concerns of the public. It establishes a standardized testing process around the two modules of "sound collection" and "sound playback", and focuses on three key evaluation dimensions: first, the frequency response index of collection and playback, which ensures that the sound reproduction of recording and playback is close to the real hearing experience of the human ear; second, the microphone collection directional performance, which assesses the equipment's ability to pick up the wearer's voice and other sounds coming from different directions, and distinguish environmental background noise;
The third is to play the sound leakage test to prevent sound leakage and protect the privacy of users' calls and listening. The relevant tests must be carried out in an anechoic room. With the help of professional high-precision measurement equipment such as head and torso simulators, measurement microphones, and acoustic analyzers, the interference of environmental reflection sound can be avoided to the greatest extent, and the test data can be ensured to be objective and reliable. Build a complete testing system for the acoustic performance of smart glasses. The "Specifications" will provide a unified measurement basis for smart glasses product R&D optimization and factory inspection, curb false parameters, and protect consumers' hearing health and call privacy.
