Brand reference:109619

On 1946-3-1, DNH A/S was established, with 50% of its shares belonging to a Swedish loudspeaker company. In the early days, DNH began producing 10, 12-inch, and 15-inch loudspeakers for bands, jukeboxes, and "Hi Fi". In 1959, the decision was made to develop re-entrant loudspeakers or horn speakers. The first explosion-proof (Ex) horn speaker was manufactured in 1962. To sustain sales, DNH Ltd. was established in Wakefield, UK, in 1983. Later, DNH WW Ltd., based in Milton Keynes (established in 1994), set up a DNH GmbH sales office and warehouse in Hamburg, Germany (in 1987), and DNH Inc. opened in Philadelphia, USA, in 2007-1.

DNH electrical components are components that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance and only opposes changes in current. If the inductor is in a state with no current flowing through it, it will attempt to oppose current flow when the circuit is closed; if the inductor is in a state with current flowing through it, it will attempt to maintain the current unchanged when the circuit is opened. Inductors are also known as chokes, reactors, or dynamic reactors. DNH electrical component principle Phototransistors, in addition to having the ability of photodiodes to convert light
