摘要： A method of manufacturing a magnetic tunnel junction device, in which a stack (1) comprising two magnetic layers (3, 7) and a barrier layer (5) extending in between is formed. One of the magnetic layers is structured by means of etching, in which, during etching, a part of this layer is made thinner by removing material until a rest layer (7r) remains. This rest layer is passivated by chemical conversion. In the relevant method, it is prevented that the magnetic layer which is not to be structured is detrimentally influenced during structuring of the other magnetic layer.

摘要： A loudspeaker that includes an acoustical enclosure that has an internal wall that divides the enclosure into first and second subchambers, an electro-acoustical transducer having a vibratable speaker cone mounted in an opening provided in the internal wall of the acoustical enclosure, an internal vent provided in the internal wall of the acoustical enclosure for pneumatically coupling the first and second subchambers, a first external vent provided in a wall of the first subchamber for pneumatically coupling the first subchamber to an exterior environment outside of the acoustical enclosure, and a second external vent provided in a wall of the second subchamber for pneumatically coupling the second subchamber to the exterior environment. In one embodiment, a ratio of the acoustic mass of the internal vent to the acoustic mass of the second external vent is in a range of approximately 3/1 to 7/1. In another embodiment, a ratio of the acoustic mass of the first external vent to the acoustic mass of the second external vent is in a range of approximately 15/1 to 30/1. In both embodiments, a ratio of the volume of the first subchamber to the volume of the second subchamber is in a range of approximately 0.3 to 2.5. In both embodiments, at least one of the internal and/or external vents can be substituted with a passive radiating element such as a drone cone.

摘要： A passive radiator comprising a frame (1) and a radiator body (3) which is connected to the frame and which is movable relative to the frame along a translation axis (T). The radiator is suitable for the displacement of comparatively large air volumes. The radiator body comprises a central mass element (3a) and at least one mass element (3b, 3c, 3d) which is concentrically arranged with respect to the central mass element. The radiator further comprises connection units (5a, 5b, 5c, 5d) for the movable interconnection of each pair of adjoining mass elements and for the movable fastening of one of the mass elements to the frame. Each of said connection units comprises at least a resilient annular connection element (5a1, 5a2; 5b1, 5b2; 5c1, 5c2; 5d1, 5d2), such that the central mass element with its adjoining connection unit forms a mass spring system, as does each concentrically arranged mass element with its adjoining connection element, while all mass spring systems thus defined have at least substantially the same resonance frequency.

摘要： A loudspeaker enclosure includes a rectangular cabinet (10) having an acoustical port (14) mounted in one of its vertical walls. A loudspeaker (18) is installed in a bottom wall (16) of the cabinet facing away from an interior volume of the cabinet. A highly resistive acoustic foam (20) is positioned in front of the loudspeaker to restrict the direct radiation of the loudspeaker, so that the usable acoustic radiation emanates from the acoustical port.

摘要： The invention relates to a device for reading and/or writing a disc-shaped information carrier (17), which comprises a support element (25) of a magnetizable material along its circumference. The device comprises an electromagnetic unit (27) for co-operation with the support element and a scanning unit (23) for reading and/or writing the information carrier. By co-operation between the electromagnetic unit and the support element, the information carrier can be rotated about an axis of rotation (73) and positioned with respect to the scanning unit (23) in five degrees of freedom, i.e. in all degrees of freedom except the rotational degree of freedom around the axis of rotation. According to the invention, the electromagnetic unit (27) comprises a single pair of rows (29, 31) of electromagnets (33, 35), which rows are arranged, along an X-axis perpendicular to the axis of rotation (73), on both sides of the information carrier. The electromagnetic unit (27) further comprises a first pair of electromagnets (37, 39) and a second pair of electromagnets (41, 43) which are diametrically arranged with respect to each other, viewed in a middle position of the information carrier (17) along the X-axis and viewed along a Y-axis perpendicular to the X-axis and the axis of rotation, the magnets of the first and the second pair being arranged on both sides of the information carrier, and the magnetic poles (69, 71) of the electromagnets of each pair being arranged at equal distances from the X-axis and, in each position of the information carrier along the X-axis, on one side of a magnetic point of application (M) of the support element. Thus, the electromagnetic unit has a comparatively simple construction and comprises a limited number of electromagnets, so that also the control unit, which is necessary to control the electromagnetic forces of the electromagnets, is simplified.

摘要： Single-channel magnetic head having a head face (1) which extends in a first direction (I) in which a magnetic record carrier (3) is relatively movable with respect to the magnetic head, and in a second direction (II) transverse to the first direction. The magnetic head has a structure of layers which, viewed in the first direction, are situated one on top of the other and extend substantially in the second direction and a third direction (III) transvese to the first and the second direction. The structure is provided with a magnetoresistive measuring element (5), a first magnetic element (7) and a second magnetic element (9). Both magnetic elements are electrically conducting, while the measuring element is arranged electrically in series between the two magnetic elements for passing a measuring current (i) through the measuring element substantially in the third direction. Each magnetic element has an electric contact face (7a, 9a). To obtain a stable single-channel magnetic head having a narrow, well-defined scanning width, at least one magnetic element extending as far as the head face has an extensiveness which is larger in the second direction than in the third direction. This extensiveness in the second direction is also larger than the effective width (w) of the measuring element. In the third direction, the relevant magnetic element has a larger relative magnetic permeability (νrIII) than in the second direction.

摘要： In order to increase the information density on storage media the track width of a written magnetic pattern is made increasingly smaller. This requires write heads having appropriate flux guides. The method disclosed in this patent document provides such flux guides. The method includes the following steps: depositing a non-magnetic layer (3) of sufficient thickness; anisotropically etching the non-magnetic layer to form a steep wall of suitable dimensions at the required position of a flux guide; depositing a magnetic material to form a magnetic layer (9) on the wall in such a manner that the magnetic layer has a thickness corresponding to the required track width; removing undesired deposits of magnetic material but maintaining the magnetic layer on the wall; depositing an insulating material (19a) to cover the magnetic layer.

摘要： A panel-shaped loudspeaker comprising a panel (1) having a first main surface (1A) and a second main surface (1B) parallel to the first main surface and further comprising an exciter (3) positioned at the first main surface. When the exciter is energized the panel is capable of sustaining bending waves and has a distribution of resonant modes of its natural bending wave vibration, which results in an acoustic radiation. The loudspeaker has a tuning element (17) extending near the second main surface of the panel and positioned opposite the exciter so as to form a resonant cavity (18) between the panel and the exciter.
