The disclosed subject matter relates to a method of final assembly of a light projector module, including the steps of: providing a base plate, a light source on the base plate, and a micro-electro-mechanical-system (MEMS) scanning assembly, wherein the base plate has, between the light source and the MEMS scanning assembly, a mounting surface accessible at one side of the base plate; positioning a set of one or more lenses on the mounting surface and adjusting the position of the one or more lenses of the set while the light source is emitting and at least one light beam projected by the light projector module is monitored in a display area; and mounting the one or more lenses of the set in the adjusted position fixedly on the base plate.

Method of final assembly of a light projector module

The disclosed subject matter relates to a light projector module, comprising: a base plate, a light source on one side of the base plate, a micro-electro-mechanical-system (MEMS) scanning assembly on the base plate, and a set of at least one lens mounted on the one side of the base plate between the light source and the MEMS scanning assembly, wherein the MEMS scanning assembly has an arm mounted on and extending from the other side of the base plate, a scanning mirror being movably mounted on the arm and facing the base plate, and wherein a light guide is mounted on the base plate or the arm for directing the at least one light beam from the lens set on the one side to the scanning mirror on the arm extending from said other side of the base plate.

A frameless audio transducer for mobile applications is provided. 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.

Frameless audio transducer for mobile applications including optionally supported coil wire and leads

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.

Electroacoustic transducer

A speaker and method for making the same are provided. The speaker includes a permanent magnet and a coil disposed about a first axis around the permanent magnet, the coil being configured to move along the first axis. The speaker further includes a membrane attached to a top surface of the coil and a stabilizer contacting at least one of an internal surface, an external surface, and a bottom surface of the coil, and configured to limit movement of the coil relative to a second axis perpendicular to the first axis.
