Abstract: An electromagnetic valve for a hydraulic system for an automatic transmission of a vehicle. An armature chamber is filled with hydraulic medium and fluidically connected to hydraulic lines of the hydraulic system. An armature is mounted in the armature chamber such that its stroke is adjustable. The armature includes a shut-off body and divides the armature chamber into an opening-side chamber facing the flow opening and into an inner chamber facing away from the flow opening. During a stroke of the armature, an oil exchange occurs, and a displacement volume of the hydraulic medium overflows from the opening-side chamber into the inner chamber. A hydraulic line leading to the opening-side chamber or to the inner chamber of the armature chamber includes a dirt collecting element that is designed as a permanent magnet and that retains contaminations in the hydraulic medium that flows through the hydraulic line during an oil exchange.

The invention relates to an audio transducer realized as speaker to transduce an electrical audio signal into acoustic sound or realized as receiver to transduce an acoustic sound into an electrical audio signal, which audio transducer is realized without a frame to align and fix the other parts of the audio transducer. The frameless audio transducer further includes coil lead support structures to reduce stress on the coil leads during operation.

Abstract: A drive device for a motor vehicle includes a primary powertrain and a secondary powertrain, wherein the primary powertrain includes a combustion engine for generating a total torque; a torque distribution device coupled to the combustion engine and including a first and a second output, wherein the torque distribution device is designed to provide a first partial torque in mechanical form at its first output derived from the total torque, and to provide a second partial torque in electrical form at its second output derived from the total torque; and a transmission which is coupled to the first output of the torque distribution device; wherein the secondary powertrain includes an electric machine which is coupled to the second output of the torque distribution device; wherein the torque distribution device includes a torque limiting device which is designed to limit the first partial torque to a presettable threshold value.

Abstract: A new audio transducer for mobile devices having a collar with side openings that provide side venting to a back volume within an enclosure. The side openings eliminate the need for a typical frame and back vents thereon, which leads to a smaller size speaker. Each of the side openings have a maximum size less than the size of an adsorber material, which prevents the adsorber material coming into contact with the magnets, coil, and membrane of the speaker. The side openings and the size thereof also permit the enclosure to be directly filled with an adsorber material. The direct filling of the adsorber leads to more even and complete distribution of the adsorber within the back volume, which, in turn, improves sound quality of the speaker.

Abstract: A new audio transducer for mobile devices, in particular for a micro speaker, having a coil assembly having a coil, a pair of leads extending from the coil, and a flexible printed circuit having a pair of contact pads to which the leads are directly electrically connected. An advantage of this new speaker is the reduced number of electrical connections between the leads of the coil and the driver of the coil. This helps to reduce the number and size of the parts of the micro speaker and aids in increasing sound quality and durability of the speaker.
