硅麦测试机:硅麦(MEMS麦克风)测试指标有哪些? 在2003年,楼氏电子发明了世界第一颗微机电麦克风(MEMS Microphone)或者称为硅麦克风(Si-Microphone),凭借其良好的性能,以及本身的可靠性一致性,迅速成为消费类产品的首选元器件。 在过去的2019年当中,全球硅麦克风的出货达到近60亿颗。当今各种智能设备的语音入口,都有硅...
It is shown that the proposed method can be used to determine the frequency response of the MEMS microphone in the frequency range of 1000Hz to 12000Hz.doi:10.1016/j.apacoust.2020.107523Denny HermawantoKenji IshikawaKohei YatabeYasuhiro Oikawa...
Figure 4 shows the normalized frequency response of several MEMS microphones of the same model; Figure 5 shows the normalized frequency response of various ECMs. The frequency response of each MEMS microphone is nearly identical, while that of the ECMs shows significant device-to-device variation, ...
Frequency response (FR) is the sensitivity of the microphone shown across the frequency range; it is usually plotted relative to the sensitivity at 1 kHz. The goal for a microphone is typically to have a flat frequency response in the used frequency band. This means that the sensitivity of t...
