1. Enabling factor: refers to the reason why the technology can be adopted. Taking the high-quality microphone used in the recording studio as an example, the enabling factors of the current analog technology microphone are: wide frequency response, large dynamic, high sensitivity and mature technology. For the recording industry, the pursuit is the high quality of sound, and the enabling factor is the main factor considered by the recording industry. Compared with home recording enthusiasts and podcast users, the first thing to consider is the cost. The low price is the enabling factor of analog-to-digital hybrid technology microphone. The hot plug function simplifies the operation steps, and saves the cost of external sound card. The sound quality can basically meet their needs. For those who have purchased analog microphone, adding a USB signal converter can The original device is compatible. The demand of home recording enthusiasts and podcast users makes USB technology microphone very popular in this kind of consumer groups.
2. Hindrance factor: refers to the limit that can be reached in the technology and the factors that inhibit the acceptance or use of the technology. Taking the microphone required by communication equipment as an example, the carbon electrode itself has limited energy conversion effect, so it is quickly replaced by ECM electret microphone. However, the ECM electret microphone can not meet the requirements of digital communication equipment in terms of volume requirements, and can not directly generate digital pulse signal, so it is replaced by MEMS microphone. Taking the microphone of USB technology as an example, the maximum transmission speed of usb1.0 standard is 1.5mbps (192kb / s). At this low rate, the digital signal transmission of microphone is not smooth, so it is unlikely to appear USB technology microphone, and the emergence of USB2.0 solves this problem. In addition, the maximum effective transmission distance of USB is 5 meters, which fundamentally determines that USB Microphone is more suitable for indoor short distance use. In the field of professional audio application, the existing analog microphone technology in professional recording studio has been very mature, which can well meet the needs of sound recorders. In addition, due to the preference factors of analog microphone, digital technology microphone is difficult to have a foothold in professional recording studio at this stage. The factor that hinders the application of technology in an industry is different from that of an industry.
