Title: Ultramicro balance unit used as sensitive suspension scales
Inventor: GREGOR MANFRED ALEXANDER
IPC: G01G1/22
Filed: 1996-11-07
Abstract: The balance unit consists of an elastic double fibre working twofold as tension and flexing fibre. So that both fibres with their tensional force carry a plate, upon which lie the weighing beam and the load. The mass of which can be as great, as the max. tensile load of the fibre. So that both fibres with their flexing and restoring force sensitively measure and stabilise the out of balance. In a determined sequence, to these masses (m) suspending in a stable balance, new masses (M) are applied from the left and the right. They are adjusted to a determined distance for a determined duration smoothly and left standing, or with approximation the movement becomes slower. After a determined duration, the new masses continue movement, and exchange to the other side in a mirror image position. With the transfer in a new position, after an interval wait, a new position is set up. The strength of the interaction so produced and the speed of movement produced can be controlled to set aim and also regulated.

IPC: H04R9/04
Filed: 1996-12-09
Abstract: An electrodynamic transducer has a membrane and a moving coil which moves into a magnetic field. Such electrodynamic transducers are widespread and because of their robustness and reliability are used even in difficult situations, for recording microphones or for playback devices. In the known electrodynamic transducers, the membrane, the moving coil and the whole magnetic system have a circular design for manufacturing technology reasons. The membrane third harmonic vibrations and self-resonance which result therefrom must be compensated by numerous measures such as beads, coatings and the like, which in part require many subsequent operations. The object of the invention is to avoid said disadvantages and to provide a high quality electrodynamic transducer. For that purpose, an electrodynamic transducer with the features of claims 1 or 2 is proposed. Advantageous developments are described in the dependent claims. In claim 1, a non-circular membrane and a moving coil of any shape are provided. The geometrical centres of gravity of the membrane and moving coil do not coincide but are spaced apart. The membrane can take any shape, for example oval, rectangular, square or even irregular. The distance between the moving coil and the edge of the membrane is not the same all around the edge of the membrane, but only in a few spots.
