Abstract
A shotgun microphone unit which includes a housing, a microphone capsule, a shotgun tube having a longitudinal axis, and a shotgun mounting for mounting the shotgun tube with the microphone capsule within the housing. The shotgun mounting has an axial and a radial mounting, wherein the axial mounting is softer than the radial mounting.
Claims10
1:
- A shotgun microphone unit comprising:
- a housing;
- a microphone holder;
- a shotgun tube having a first end and a second end;
- and
- a shotgun mounting having an axial mounting and a radial mounting for mounting the shotgun tube to the housing;
- wherein the shotgun tube has a longitudinal axis and a microphone capsule at its second end, wherein the first end of the shotgun tube is in the form of an open end;
- wherein the axial mounting is softer than the radial mounting;
- wherein the shotgun tube has at least two mutually opposite fixing units and the microphone holder has at least two arms;
- wherein spring elements are respectively provided between the arms and the fixing units;
- and
- wherein the arms are L-shaped and respectively hare a portion oriented parallel to the longitudinal axis for receiving the spring elements.
9 more elements
2:
- The shotgun microphone unit as set forth in claim 1;
- wherein the shotgun tube mounting has a first and a second mounting unit which are adapted for structure-borne sound isolation between the shotgun tube and the microphone holder respectively;
- wherein the first and second mounting units are arranged along the longitudinal axis of the shotgun tube;
- and
- wherein the at least two mutually opposite fixing units, the at least two arms, and the spring elements form at least one of the mounting units.
2 more elements
3:
- The shotgun microphone unit as set forth in claim 1;
- wherein the at least two arms of the microphone holder are of an L-shaped configuration and respectively have a free end having an angled portion oriented parallel to the longitudinal axis for receiving the spring elements.
4:
- The shotgun microphone unit as set forth in claim 1;
- wherein the microphone holder and the shotgun tube are provided within the housing and the housing completely encloses the microphone holder and the shotgun tube.
5:
- The shotgun microphone unit as set forth in claim 1;
- wherein the spring elements are of a cross-section which is greater in the radial direction than in the axial direction.
6:
- The shotgun microphone unit as set forth in claim 2;
- the microphone holder has at least two second arms and the second spring elements are respectively coupled to the free ends of the second arms and the second fixing units;
- wherein the second fixing units are provided at opposite sides of the shotgun tube;
- and
- wherein the free ends of the second arms are provided at opposite sides of the shotgun tube;
- and
- wherein the second fixing units, the second spring elements and the second arms form the second mounting unit.
4 more elements
7:
- The shotgun microphone unit as set forth in claim 1;
- wherein each spring element comprises two U-shaped spring segments which are substantially arranged in a plane.
8:
- The shotgun microphone unit as set forth in claim 5;
- wherein the cross-section of the spring elements in the radial direction is greater by at least the factor 1.5 than in the axial direction.
9:
- The shotgun microphone unit as set forth in claim 1;
- wherein the housing is sound-permeable.
10:
- The shotgun microphone unit as set forth in claim 1;
- wherein the spring elements are arranged substantially transversely to the longitudinal axis.
