March 26, 2018 – The latest worldwide distribution of semiconductors and electronic components, Mouser Electronics, is now stocked with Infineon Technologies' IM69D120 and IM69D130 XENSIVTM MEMS microphones. These high-performance, low-noise microphones are ideal for applications such as high-quality recording, voice user interfaces, active noise reduction, or audio mode detection in surveillance systems.
The Infineon XENSIV microphone from Mouser Electronics is designed for applications that require low self-noise, wide dynamic range, low distortion and high acoustic overload points. These microphones use Infineon's dual backplane microelectromechanical systems (MEMS) technology to deliver high linearity signals in dynamic ranges up to 105 dB. The dual-backplane MEMS technology uses an ultra-small symmetrical microphone design that, like the condenser microphone used in the studio, produces a true differential signal. This technology boosts high frequency immunity, ensures better audio signal processing, and increases the total harmonic distortion (THD) 10% acoustic overload point to 135 dB SPL.
These sizes are only 4 mm & TImes; the 3 mm microphone has a noise floor of only 25 dBA (69 dBA SNR), and the distortion rate is less than 1% even at 128 dB sound pressure level. To ensure design flexibility, the IM69D120 microphone is specifically designed to maintain a signal-to-noise ratio of 69 dBA over the dynamic range of a 16-bit system, while the IM69D130 is suitable for 20-bit systems. Compared to traditional MEMS microphones, the signal-to-noise ratio of these two microphones is increased by 5 dB, which means that the distance between the user and the device that captures the voice command can be doubled. In addition, these microphones have a flat frequency response and minimal manufacturing tolerances, making them tightly phase matched, making them ideal for microphone array applications.
TWS, means true wireless stereo. The implementation of this technology is based on the development of bluetooth chip technology. Technically speaking, it means that the mobile phone is connected to the main speaker, and then the main speaker is connected to the speaker through the Bluetooth wireless mode, thereby realizing the true separation of the left and right channels of the Bluetooth. When the slave speaker is not connected, the main speaker returns to the mono sound quality. TWS technology is used in the field of Bluetooth Headsets, so it has also spawned a new product - TWS Bluetooth headset.Since the TWS Bluetooth headset does not require a wired connection, the left and right earphones form a stereo system through Bluetooth, and the convenience of listening, talking, and wearing are improved.
Advantages:
1. True wireless structure, completely abandon wired troubles, and exercise more freely.
2. Various ways of use, both exclusive and shared, and can also be used as two earphones.
