摘要： A microphone includes a separate end cover with a sound port. A diaphragm is directly attached to the end cover. The backplate is positioned within the housing against a ridge near an end of the housing. A spacer is positioned against the backplate. The diaphragm engages the spacer when the end cover, with its attached diaphragm, is installed in the housing. The backplate of the microphone has an integral connecting wire that is made of the same material as the backplate. The integral connecting wire may have an inherent spring force to provide a pressure contact with the accompanying electrical components. The integral connecting wire electrically couples the backplate to the electronic components within the housing and transmits the raw audio signal corresponding to movement of the diaphragm. The housing may have first and second ridges on which the printed circuit board and the electret assembly are mounted, respectively.

摘要： An electroacoustic transducer comprising a case accommodating an armature with at least two armature legs (6); a coil (9) with an air gap, which is fitted around one armature leg (6a); a magnetic element (7, 8) with an air gap which is likewise fitted around the one armature leg, with the air gap of the coil and that of the magnetic element being located in line with each other; a diaphragm (4); and a connecting element (5) which couples a free end of the one armature leg to the diaphragm; and a printed circuit board (14) with terminals (15) for the wires of the coil and for external connections. According to the invention, the coil is attached to the printed circuit board by an end face thereof which is located essentially perpendicularly to the longitudinal axis of the air gap, and the printed circuit board is provided with at least one recess adapted to cooperate with a leg of the armature. Through these measures, the coil can be positioned symmetrically with respect to the armature leg with very high accuracy.

摘要： A transducer comprising a coil having a first air gap, a magnetic member having a second air gap and an armature. The armature includes an armature leg that extends through the first and second air gaps. The armature leg is capable of movement within the air gaps. The magnetic member includes at least one nub extending into the second air gap. The nub limits the movement of the armature leg within the second air gap.

摘要： A microphone and method for dampening the frequency response of the microphone by disposing a dampening frame (8) in a rear volume of the microphone. The microphone generally includes a housing (4), a diaphragm (6), a damping frame (8), and a backplate (10). The diaphragm rests on embossments (14) in the housing, and a damping frame including a damping slit (32) cut into an inner edge of the damping frame (8) is positioned against the diaphragm. The backplate is positioned adjacent the damping frame to define an aperture (36) which allows air to escape from the area between the backplate (10) and the diaphragm (6) into the rear volume of the microphone, thus dampening the frequency response of the microphone.

摘要： A directional microphone includes a housing, a diaphragm dividing the housing into a front volume and a back volume, electronics for detecting signals corresponding to movements of the diaphragm, and front and back inlets for the front and back volumes, respectively. To obtain additional low frequency roll-off in the directional microphone, the directional microphone includes an elongated acoustical conduit connecting the front volume and the back volume. The acoustical conduit may be external or internal to the housing.

摘要： A method for manufacturing an electroacoustic transducer for, for instance, a hearing aid, with a diaphragm (5) arranged in a housing (2). According to the invention, the diaphragm is attached onto a film or punched from a sheet of material, such that along the circumferential edge of the diaphragm, a free strip of film or a strip of material (7) remains present. In a capillary space between the circumferential edge of the film and the inner wall of the housing, or in a capillary space (8) between the diaphragm and the strip of material, a polymer of a low viscosity is provided to connect the diaphragm with the housing wall. Through the method, the production of the transducer is greatly simplified.
