Abstract
1,274,875. Loudspeakers. GUIDANCE TECHNOLOGY Inc. 21 May, 1969- No. 25793/69. Heading H4J. [Also in Divisions H1 and H2] A system for importing movement to an ionizable dielectric fluid medium comprises a pair of spaced electrodes with a D.C. source connected across them and a control electrode located between them, the electrodes being immersed in the fluid and constructed so that the fluid can flow through them. In the embodiment shown in Fig. 1, the rate of flow of an ionizable, dielectric fluid produced by the application of a high D.C. voltage to electrodes 11, 13 is controlled by varying the electrostatic potential of the control electrode 12. The electrode 11 is in the form of a wire grid and electrode 13 comprises a set of parallel plates the combined surface area of which is greater than that of electrode 11. The control electrode 12 also comprises a wire grid having a surface area between those of electrodes 11, 13. The emissivity of the electrodes 11, 13 may be improved by coating them e.g. with caesium, barium chloride, thorium oxide or radioactive materials. Alternatively the electrodes may be heated. For example, electrode 11 may be heated through a step-down transformer 19 and the plates 13a of electrode 11 may incorporate heating elements connected to a suitable power supply. The D.C. potential applied to the control electrode may be modulated by an A.C. signal so that pressure waves are produced in the dielectric fluid. The signal may be applied through a transformer (23), Fig. 4 (not, shown), in series with electrode 12 or through a, single stage pre-amplifier (25), Fig. 5 (not shown). In these cases the devices may function as electro-acoustic transducers. Fig. 6 shows a loudspeaker utilizing a pair of devices according to the invention in push-pull. A common anode electrode 11 is located between a pair of cathode electrodes 13 and has a pair of control electrodes 12 disposed on opposite sides thereof to which the modulating signal is applied either through a transformer 33 or through a pre-amplifier stage comprising a pair of triodes in push-pull, Fig. 6 (not shown).
