Abstract: A microphone assembly comprising: a microphone for converting an acoustic signal to an electrical microphone signal; a tube enclosing at least a part of a first conductor for conducting the microphone signal, the tube comprising a rigid first tube part and a rigid second tube part. The first tube part has a first primary tube end and a first secondary tube end, wherein the microphone is attached at the first primary tube end. The second tube part has a second primary tube end and a second secondary tube end. A first rotating connector between the first tube part and the second tube part allows rotating the first tube part in relation to the second tube part about a first rotation axis.
Abstract: A microphone system includes a microphone with a microphone output for converting a first acoustic audio signal to a microphone signal, the system including: a head part including a loudspeaker with a loudspeaker input for converting a loudspeaker signal to a second acoustic audio signal; a first connector for connecting the system to an auxiliary device and including a housing and a first terminal; a unit for preprocessing the microphone signal having at least a first input connected to the microphone output, a first output connected to the loudspeaker input, and a second output connected to the first terminal. The unit is configured to: receive the microphone signal on the first input to form a input signal; and process the input signal to form first and second output signals on the first and second outputs, respectively, the first output signal and the second output signal based on the input signal.
Abstract: A microphone assembly is disclosed, the microphone assembly comprising: a microphone for converting an acoustic signal to an electrical microphone signal; and a rigid tube with a first tube end and a second tube end. The microphone is attached at the first tube end. The rigid tube encloses at least a part of a first conductor for conducting the microphone signal. The rigid tube has a first tube part extending along a first axis, and the rigid tube has a first bend between the first tube end and the first tube part. A clamp member is mounted on the rigid tube, wherein the clamp member is configured for clamping the microphone assembly to a piece of clothing placed between a clamping section of the rigid tube and a clamping section of the clamp member.
Abstract: Microphone array for achieving a substantially frequency-independent directivity using a plurality of microphones disposed along a rectilinear array. The rectilinear array is at least as long as the wavelength of the lowest frequency, where a useful directivity is desired. The rectilinear array has a first end and a second end. The microphones close to the first end are intended for the highest frequencies and the microphones close to the second end are intended for the lowest frequencies. The mutual spacing of the microphones is frequency-dependent. The signals from the individual microphones are band-pass filtered, the passbands and cut-off frequencies of the individual band-pass filters being adapted to the frequency band the individual microphones are intended for.
