摘要： A microphone includes a housing. The microphone includes a windscreen coupled with the housing. The windscreen and the housing define a central volume. The microphone includes an audio module within the central volume. The audio module includes a receiver capsule, a carrier unit coupled with the receiver capsule, and a counterweight coupled with the carrier unit. The microphone includes a suspension element that is coupled with the housing and carrier unit to suspend the audio module within the central volume. The suspension element includes an inner body that contacts the carrier unit. The suspension element includes first and second flanges extending outward from the inner body. The first and second flange are fixedly coupled with the housing. A cross-section of the first and second flange includes an arched region that extends at least partially to an inner wall of the housing. The arched regions are oriented in opposite directions.

摘要： A microphone assembly having a particle filtration system. The microphone filtration system may include an outer support structure, at least one filtration layer, an inner support structure, and a sleeve. The microphone filtration system is configured to seal a transducer chamber of the microphone assembly from the outside environment, and trap particles that may buildup and corrode a transducer housed by the transducer chamber. The at least one filtration layer of the particle filtration system provides a Minimum Efficient Reporting Value (MERV) rating greater than or equal to 13 while minimizing attenuation and distortion of the soundwaves entering the transducer chamber.

摘要： This application discloses a wind noise suppression device including a first woven mesh (101), a second woven mesh (102), a device housing (103), and a structural component (104). The device housing (103) is provided with a sound pickup hole (1031). The first woven mesh (101) covers the sound pickup hole (1031). The structural component (104) is disposed at the sound pickup hole (1031). The structural component (104) is connected to the device housing (103) to form a cavity. The structural component (104) is provided with a sound transmission hole (1041). The second woven mesh (102) covers the sound transmission hole (1041). A microphone is disposed at the sound transmission hole (1041). Because structural characteristics of all the components the device, wind noise included in an audio signal received by the microphone through the sound transmission hole (1041) is effectively reduced.

摘要： A time at which a failure of a noise level meter has occurred is accurately determined. The present invention relates to a noise measuring device including a noise level meter having a main microphone capable of measuring noise, and a sub microphone capable of measuring noise at the same time as the main microphone. The present invention also relates to a failure diagnosing system having the noise measuring device and a failure diagnosing device capable of diagnosing a failure of the main microphone. The present invention also relates to a failure diagnosing method for diagnosing a failure of the main microphone. In the failure diagnosing system and the method, the presence or absence of a failure of the main microphone in the noise level meter is diagnosed based on the comparison between main and sub noise data obtained by the main and sub microphones and respectively in each of a plurality of recording periods.
