Headphone

Abstract

The invention relates to a headphone. A mechanical device, which holds the stationary state of a movable part relative to the other part up to a defined limit, is referred to as a brake mechanism. In a device having two parts which can be moved relative to each other, a magnetic brake mechanism is provided, the two parts which can be moved relative to each other can move relative to each other in a predetermined direction, and the magnetic brake mechanism comprises two multi-pole magnetized magnetic films. Each multi-pole magnetized magnetic film is fastened to one of two parts that are movable relative to each other. The two multi-pole magnetized magnets are moved at a small distance from each other when the two parts that can be moved relative to each other are moved relative to each other in the predetermined direction. In this case, the magnetic force acting between the parts affects the force required for the movement and defines a preferred position or a latching position, in which opposite magnetic poles lie opposite each other. The magnetic brake mechanism may be used for an adjustable bow of a headphone.

Description

technical field [0001] The invention relates to a device with a movable part and a brake, in particular a magnetic brake. Background technique [0002] In many different devices, for example in the bow of adjustable headphones, but also in closures or slide switches, parts can be moved relative to each other or adjusted mechanically. In this case, the defined displacement position set by the user should generally be maintained as much as possible, while the force applied by the user for the displacement should at the same time be as low as possible. In this case, a mechanical device called a locking mechanism or braking mechanism is usually used. A locking mechanism can completely or up to a defined limit hold a basically movable part in a stationary state relative to another part by means of a locking element. In the latter case, it is the braking mechanism. For example, usually based on figure 1 A brake that works according to the principle shown can be used as a locki...

AI Technical Summary

Problems solved by technology

[0003] Such mechanical locking or detent mechanisms have various disadvantages, such as a large number of usually small components, which can be difficult to install

Due to this, installation is usually relatively expensive

Furthermore, the shape of the spring 140 (especially when eg bending elements are involved) as well as the shape of the recess 115 may wear out with use.
