Wireless Lavalier Microphone Sunpu ZBR-MKF used a certain Burundins Escort East platform to compare the two products. My most intuitive feeling is that “you get what you pay for” Distribute goods.” What is a bit regretful is that the product introduction of Rhodes Wireless GO II specifically mentions “omnidirectional condenser microphone”, but the electret microphone unit seen after disassembly does not have any silk screen information to confirm the brand and model. The microphone unit of Xunpu ZBR-MKF is wrapped in a rubber sheath on the inside and dust-proof cotton on the outside. It is tightly wrapped, and it is impossible to confirm the brand and model of the MEMS device. But there is no doubt that MEMS sensors, as the core device of radio performance, play a role that cannot be ignored. Voice pickup and Burundins Escort noise reduction technology are also audio The lifeblood of the product. The Sony Bee product introduction also specifically mentions electret condenser microphones. The leading chip manufacturers in the industry include Knowles and Goertek.

The internal circuit has been optimized and selected, and is suitable for hazardous areas and explosive surroundings. Environmental requirements (mines, gas stations, hazardous gas chemical plants, etc.), can be safely used in environments around gas hazards. Standard measurement microphones in these surrounding situations may cause sparks or fires. 2023-04-26 15:52:35712Requesting a design plan for the recording pen circuit. Setting up the recording pen circuit requires some basic electronic circuit knowledge and skills. The detailed steps are as follows: Clear recording The working principle of the sound pen: The recording pen picks up the sound through the microphone and converts it into an electronic signal, then amplifies the electronic signal through an amplifier, and then converts it through an analog-to-digital converter 2023-04-20 14:29 :39 Sennheiser releases the fifth generation wireless microphone system, specially designed for photography Sennheiser Evolution Wireless Digital: EW-DP Sennheiser releases the fifth generation wireless microphone system, specially designed for photography Wedemark, 2023 April 14, 2020 – Sennheiser released its fifth generation at NAB 2023-04-19 17:14:411112i.MX8MM SAI1 How to connect 8 microphones? Can anyone give me some tips on the i.MX8MM SAI1 interface? I plan to use SAI1 RX interfaceConnect 8 digital microphones, each with an I2S interface. The SAI1 RX interface only needs one frame to be output synchronously. Does anyone know how I can connect all 8 microphones in this situation? 2023-04-17 08:34:01 The sampling rate of the I2s microphone seems to be only half of what is expected. What is the reason? I’m using INMP441 i2s microphone (datasheet) and creating an fft series using esp-dspBI Escorts library and esp-idf 5.0.1 . I sampled at a frequency of 10 240 Hz, but I couldn’t see anything higher than 2023-04-13 06:35:11 Filmless optical microphone, which can hear the widest range of sounds. Hongke optical microphone uses patented filmless technology, It is not affected by mechanical parts and has a wider detection range. It can be used for sound field measurement, non-destructive testing and process monitoring. 2023-04-10 10:07:181042Give a friend a low-impedance microphone amplifier circuit. This circuit is a microphone amplifier with low impedance. Typically, a low-impedance microphone is found in a dynamic microphone. This microphone amplifier circuit can work normally from 6 VBI EscortsDC voltage to 30 VDC voltage.
