上周苹果 iPhone 新机发布，而在发布之前，确实有部分资金选择落袋为安、获利了结 ，从零 组件 族群里 撤出 。原先 我们 说的 iPhone7S 、iPhone7S Plus、iPhone8，官方正式命名分别为 iPhone8、 iPhone8 Plus、 iPhoneX，三款新机基本和大家猜测的也都差不多，再加上 iPhoneX 整个供给量根本跟不上，表定10/27 接受预订、 11/03 才开始出货，比多数人预期的晚了 5~6 周(不过我们 4~5 月就明确指出 iPhone 迟到了，10 月底以后量才会释放出来)，因此发布会后苹果概念股也持续疲弱，资金继续从零组件族群里撤出、近期股价依然向下修正。

As of 2016, pico projectors are sub-1 pound with internal batteries and have an output of no more than 100 lumens with many producing 10 to 50 lumens. Many of the pico projectors are available on Amazon, the US website; however, pico projects from major brands including Vivitek, Optoma, and Sony are not available online. Most of the pico projectors run up to 2 hours on their internal batteries and have 6 or 12-volt chargers and adapters. Though external battery packs option is available, it is not offered by the manufacturers.

QSFP is an optical transceiver module used in optical fiber communication systems. The main function of this module is photoelectric conversion. In an optical fiber communication system, the information is sent in the form of light pulses, which is then converted into electrical signals in order to be utilized by an electronic device. The transmitter then converts the electrical signal into an optical signal, which is coupled to a connector. The receiver then converts the optical signal, which is transmitted through a fiber optic cable, into an electrical signal. There are different types of fiber optic transceivers available in the market including CFP, QSFP, QSFP+, SFP, and SFP+. The different types of fiber optic transceivers are described below:

A headset – a combination of a headphone and a microphone – has a wide range of functionalities in industries including media and entertainment, sports, gaming,corporate, commercial aviation, and defense. The demand for sophisticated and hightech headsets will see considerable growth over the coming years. The rise in disposable income, establishment of strong distribution networks, focus on personnel comfort, and the emergence of portable music systems such as smartphones, tablets,and digital audio players are the prime factors driving the market for personal use headsets. The demand for attractive and modern designs and styles will also impact the market positively. The corporate and commercial sectors are likely to see strong growth in demand owing to the use of headsets in business process outsourcing (BPO) organizations and digital innovations within the media and entertainment domain,including music industry.

Environment monitoring and sensing refers to long-term measurement and observation of the air, aquatic, and soil sources. It involves taking multiple samples and measurements for assessing the characteristics of different substances. For instance, the physical, chemical, and biological components of water determine if it is safe for consumption or use in a particular application.An environmental sensing and monitoring system consists of satellites, portable ground and remote sensors, and measurement and model data. Environmentalsensing and monitoring technologies are used in forest fire detection, air pollution monitoring, greenhouse gas (GHG) monitoring, and landslide detection. The demand for environmental sensing and monitoring devices has increased in a wide variety of applications over the last decade.

A speaker is an audio system that converts electromagnetic waves into sound waves. Portable speakers can be categorized based on technology into two types: wired and wireless portable speakers. The demand for wired speakers is fast declining because they use wired technology. A cable is used to connect the speaker to the source. The audio signal is transferred through the cable. The quality and speed of data transfer are relatively fast compared with wireless speakers.

Quantum dots are nanocrystals made of semiconductor materials. They exhibit extraordinary optical properties when excited. Quantum dots are capable of emitting fluorescent light of different intensities depending on their size and tuning. They can be tuned according to the requirement of absorption wavelength or emission, and this has led to their increased commercialization.
