The invention involves the employment of a non-acoustical transducer embodying one non-acoustical sensor (or more non-acoustical sensors) which is adapted to sense acoustical sounds. The invention for realizing an Active Noise Cancellation device involves the replacement of the acoustic microphone (or microphones) in the said device with the aforesaid one non-acoustical sensor (or more sensors).

A system including a work string and an acoustic device for sensing or transmitting an acoustic signal at least partially traveling through a borehole fluid within a wellbore and a method of operation. The acoustic device includes a compensation fluid, an acoustic transducer at least partially disposed in the compensation fluid and configured to sense the acoustic signal, and a metallic cover that separates the compensation fluid from the borehole fluid and configured to deform in response to a pressure difference between the borehole fluid and the compensation fluid. The acoustic device is conveyed into the wellbore and an electric signal is sent or received with the processor to or from the acoustic transducer.

The disclosure generally relates to a conductive layer having one or more protrusions configured to attract an electrostatic discharge (“ESD”) arc. The device may be any device, such as a smartphone, tablet, earbuds, etc. The device may include a microphone and, therefore, may include a microphone opening. The conductive layer may include a conductive opening axially aligned with the microphone opening and one or more protrusions extending radially inwards towards the center of the conductive opening.

A terminal device includes a housing, a microphone, a sound guide support, a circuit board, and a vibration assembly. The housing is provided with a sound collecting hole, the sound guide support and the circuit board are disposed in the housing, the sound guide support and the circuit board form a first cavity, the vibration assembly is disposed between the sound guide support and the circuit board and separates the first cavity into a sound guide channel and a second cavity, and the microphone and the sound collecting hole are respectively disposed at both ends of the sound guide channel.

The present invention relates generally to the field of accessories for musical instruments and specifically to a guitar microphone holder. The holder has a body, a microphone mount attached to a central portion of the body and two arms that extend downwardly from the central portion. The body and arms of the device further resemble one or more musical notes. The holder is flexible, such that it applies a compression force that retains the device on the musical instrument.
