Pressure gradient pickup
First Claim
1. A pressure gradient pickup, comprising a housing, a diaphragm mounted in the housing, the housing defining at least two openings for sound entry, means for conducting the sound entering the sound entry openings to a rear side of the diaphragm, wherein phase-shifting sections which act acoustically are in connection to the sound entry openings, wherein the improvement comprises that the sound entry openings are located adjacent the diaphragm edge and at least approximately in the same plane as the diaphragm, the sound entry openings being arranged individually and spaced apart from one another, wherein at least one of the sound entry openings has an acoustical damping which is greater than that of the remaining openings.

Abstract
A pressure gradient pickup, particularly a capacitor microphone or a dynamic microphone, has a diaphragm arranged in a housing and at least one sound entry opening which conducts the sound to the rear side of the diaphragm. Acoustically acting phase-shifting sections are connected in the interior of the housing to the at least one sound entry opening. The at least one sound entry opening is located at least approximately in the same plane as the diaphragm and is preferably arranged concentrically relative to the diaphragm edge.
