Abstract
There is provided a microphone assembly, comprising a base body portion comprising a top plate at its distal end; and a dome portion mounted at the distal end of the base body portion and having a perforated structure with at least 50% of outwardly facing surface area of the dome portion being formed by open areas, the dome portion made of a plastic material; at least one microphone capsule located within the dome portion, and an RF antenna located within the dome portion, the top plate comprising a reflection cone pointing towards the dome portion in order to reflect sound axially impinging on the reflection cone radially outwardly.
Claims19
A microphone assembly, comprising:
- a base body portion with a top plate at its distal end;
- and
- a dome portion mounted at the distal end of the base body portion,
- wherein the dome portion is perforated,
- wherein the dome portion includes plastic material, and
- wherein the dome portion further comprises:
- a microphone capsule located within the dome portion, and
- an radio frequency (RF) antenna located within the dome portion,
- wherein the top plate comprises a reflection cone,
- wherein the reflection cone is configured to reflect sound,
- wherein the dome portion comprises an outer dome and an inner dome inside the outer dome, wherein the inner dome and the outer dome each comprise the plastic material and each have an axial direction and a radial direction and each comprise a plurality of parallel radially extending pillars, wherein the pillars of the inner dome are located at an angular off-set with regard to the pillars of the outer dome, and wherein the microphone capsule and the RF antenna are located within the inner dome portion.
A method of manufacturing a microphone assembly, comprising:
- inserting an inner dome into an outer dome;
- rotating the inner dome and the outer dome relative to each other;
- positioning the inner dome and the outer dome with snap-in elements at proximal end portions of the inner dome and the outer dome;
- and
- fixing the proximal end portion of the outer dome at a distal end of a base body portion;
- wherein the inner dome and the outer dome each comprise a plurality of parallel radially extending pillars, wherein the pillars of the inner dome are located at an angular off-set with regard to the pillars of the outer dome, and wherein a microphone capsule and an RF antenna are located within the inner dome portion.
A microphone, comprising:
- a base body portion with a distal end;
- a top plate physically coupled to the distal end;
- a dome portion mounted at the distal end of the base body portion comprising:
- an outer dome with a first set of pillars,
- an inner dome with a second set of pillars,
- wherein the first set of pillars are angularly offset from the second set of pillars, and
- wherein the outer and inner domes comprise plastic material;
- a microphone located within the dome portion;
- an radio frequency (RF) antenna located within the dome portion;
- and
- a reflection cone physically coupled to the top plate configured to reflect sound.
