A motor vehicle lock having a locking mechanism with a rotary latch and at least one pawl, comprising an electric drive unit. The drive unit interacts at least indirectly with the locking mechanism, and the drive unit has an electric motor with an output shaft and an output means secured to the output shaft, wherein means for guiding and/or binding a lubricant are arranged between the electric motor and the output means.

Motor vehicle lock

A component carrier for substantially electrical components (), in particular for electrical/electronic components () as parts of motor vehicle locking systems, preferably motor vehicle door lock component carriers, comprising a main part () and at least one side wall (), wherein the side wall () is detachably connected to the main part () at least in some regions.

Component carrier for substantially electrical components

The invention relates to a method for connecting an electric component to an electrical component support and an electrical component for an electrical component support, in particular for a motor vehicle. According to the invention, an electric component is connected to an electrical component support which comprises a base part and an electrical conductor paths arranged therein. At least one electric contact connected to the electrical component is moved in the base part such that the electric contact is electrically connected to the conductor path. The invention also relates to two electric contacts which are connected to the electric components and which are connected, according to the claims, to two different conductor paths in the base part. Said electric components can comprise more than two electric contacts, which according to the claimed method, are connected to the conductor paths of the base part.

Method for connecting an electrical component to a component support, and device

A door leaf includes a stiff, light structural part that maintains fed-in vibrational energy and, by flexural waves, propagates this energy in at least one active surface perpendicular to its thickness to distribute resonance mode vibration components over at least one surface, which has specified, preferred locations or sites within it for transducer devices, which are affixed on the structural part at one of the locations or sites to set the structural part into vibration and to allow it to resonate, thus creating an acoustic radiator that delivers an acoustic output signal when it vibrates in resonance, the front and/or the rear cover panel of the door leaf being part of the stiff, light structural component. The transducer(s) is/are situated between the cover panels. This arrangement provides a door with a loudspeaker function, which needs no extra volume compared to an ordinary door, and which is able to provide sound reliably and comprehensively to one or more rooms, which adjoin this door acting as a loudspeaker. Advantageously, additional loudspeakers or loudspeaker boxes are not required in a room that receives sound by this door with loudspeakers.

Door with structural components configured to radiate acoustic energy

The invention relates to an electromagnetic driver comprising a soft magnetic core in the form of an E with three legs and a back, an alternating field driver, magnetically coupled to the soft magnetic core, for generating an alternating magnetic field in the soft magnetic core, depending upon a sound signal, a constant field driver magnetically coupled to the soft magnetic core for generation of a constant magnetic field in the soft magnetic core, a soft magnetic element for coupling to the plate of the planar diaphragm loudspeaker, lying opposite the back and magnetically closing the legs across at least one small induction gap, whereby the constant field and the alternating field are asymmetrically superimposed such that a resulting force, or a resulting torque on the soft magnetic element, is proportional to the sound signal.

Electromagnetic driver for a planar diaphragm loudspeaker

The invention relates to a planar loudspeaker comprising a light, thin soundboard () which may be energized to produce multiply-reflected bending waves, a surrounding frame () holding the soundboard () in an articulated, shear-resistant manner; at least one driver () connected to the soundboard () to energize the soundboard (); and at least one bridge (), rigidly connecting the at least one driver () to the frame (), wherein the bridge or at least one of the bridges () is connected to the damping board ().

Door with structural components configured to radiate acoustic Energy

A flat panel loudspeaker arrangement with several panel loudspeakers of similar construction is disclosed. The panel loudspeakers are arranged seamlessly side-by-side and are rigidly connected with one another along their respective edges with a high shear strength. The panel loudspeakers can be supported by an existing stable wall.
