Abstract:
Ein Übertragerbauelement (1) umfasst ein erstes Kernteil (10) mit einem Mittelschenkel (11) und ein zweites Kernteil (20) mit einem Mittelschenkel (21), wobei sich eine Stirnseite (110) des Mittelschenkel (11) des ersten Kernteils (10) und eine Stirnseite (210) des Mittelschenkels (21) des zweiten Kernteils (20) gegenüber stehen. Das erste und zweite Kernteil (10, 20) weisen jeweils eine Auflagefläche (130, 230) mit einer jeweiligen Steigung auf. Eine Breite eines Spalts (30) zwischen der Stirnseite (110) des Mittelschenkels (11) des ersten Kernteils (10) und der Stirnseite (210) des Mittelschenkels (21) des zweiten Kernteils (20) ist von einer Position, an der die Auflagefläche (130) des ersten Kernteils (10) an der Auflagefläche (230) des zweiten Kernteils (20) anliegt, abhängig.
Abstract:
An apparatus and method for optimizing a parametric emitter system having a pot core inductive device coupled between an amplifier and emitter. The pot core inductive device allows for adjustments of the air gap formed between the two halves of the pot core structure to adjust its inductive value. This post-manufacture adjustability allows for corrections of differences caused by operations of other components in the audio system and to account for slight differences in the electrical circuit of different amplifier/emitter combinations. As efficiency of the system is dependent on the functional relationship between the amplifier, inductive device, and emitter, this allows for fine tuning of the signal to obtain high quality.
Abstract:
The inductor core (5) has a higher magnetic permeability than air, and comprises an endless channel adapted for containing an inductor winding (2), where the inductor core extends along a first axis A, and the inductor winding (2) extends completely around the first axis A of the inductor core (5) in such a way that the inductor winding (2) has a number of discrete positions or first sections (3) where it extends in a direction being perpendicular to the first axis A of the inductor core (5), and wherein the inductor winding (2), between the discrete positions or first sections, has second sections (4) where it extends at least partly along the first axis A.
Abstract:
A biased gap inductor includes a first ferromagnetic plate, a second ferromagnetic plate, a conductor sandwiched between the first ferromagnetic plate and the second ferromagnetic plate, and an adhesive between the first ferromagnetic plate and the second ferromagnetic plate, the adhesive comprising magnet powder to thereby form at least one magnetic gap. A method of forming an inductor includes providing a first ferromagnetic plate and a second ferromagnetic plate and a conductor, placing the conductor between the first ferromagnetic plate and the second ferromagnetic plate, adhering the first ferromagnetic plate to the second ferromagnetic plate with a composition comprising an adhesive and a magnet powder to form magnetic gaps, and magnetizing the inductor.
Abstract:
An inductive component in accordance with the invention includes a core which is connected to a base via a film having an adhesive coating on at least one side. In a preferred form, the core is made of a magnetic material such as ferrite and the base has a plurality of metalized pads attached thereto for electrically and mechanically connecting the component to a printed circuit board (PCB). The component further includes a winding of wire wound about at least a potion of the core, with the ends of the wire winding being electrically and mechanically connected to the metalized pads.
Abstract:
An inductor (10) includes a core (14), a coil (12) disposed about the core, and a shield (40). The shield and the core are connected to each other so that a closed magnetic loop is formed. The core may be a single piece or made up of a pair of core segments (50, 52). The shield may include two halves or portions or may include a cover with a base. The core may be unitary with the shield at one or both ends thereof. In embodiments where the shield includes two portions, the portions may have substantially identical geometry and dimensions.
