Title: Improvements in or relating to electric soundboxes
IPC: H04R19/06
Filed: 1929-06-04
Abstract: 332,996. Voigt, P. G. A. H. June 4, 1929. Gramophone pick-ups.-An electrostatic pickup comprises a non-plane diaphragm the displacement of which causes a capacity change. Fig. 1 shows a sound box combined with an electrostatic microphone of the kind described in Specification 263,300. A sheet of foil J is insulated from the back plate A by a thin air cushion, and a sheet of insulating material R. A screw H makes contact with the foil and engages insulating material G plugging the usual sound opening. Variations of a.ir pressure produced by movements of the conical diaphragm B produce corresponding movements of the foil J and vary the capacity of the condenser comprising the plate A, dielectric K and air cushion and the foil J. In a modification, a diaphragm Q, Fig. 3, of the shape of the cap of a sphere, forms the moving electrode of the con. denser. An internal electrode M is insulated from the back plate A by material N, and the diaphragm is driven by spokes R secured to a hub S. As the thin air cushion causes the diaphragm to appear stiff, the stylus D may be made springy by cutting it down as at P to avoid excessive record wear. Damping is introduced by a flat spring V fixed to the needle holder Wand pressing on a fibre plate U fixed to the end of the stylus. In another modification, Fig. 4, the internal electrode M may be cut away to provide an air chamber X communicating with the space behind the diaphragm by small holes Y which serve as damping means. The damping holes may open into the air. A foil electrode Z may be electrically connected to the internal electrode M. Specification 332,995 also is referred to.

The staff is fitted with a similar key and a magazine, Fig. 2, is provided for a number of key-tickets 22 which are normally locked in but can be released by the use of the staff. A key-ticket can be inserted at any time in an appropriate magazine through a slot 24 in a disc rotatable clockwise only. A keyticket can be withdrawn only through the opening closed by a plate 25 when this is opened by a staff inserted in the keyhole 28. Contacts are arranged in apparatus at the two stations by which the starting signal may be controlled so that it cannot be pulled off for a second train until the first has arrived. Fig. 1 shows the circuits at a sending station A and a receiving station B, the line wire not being shown. The authorizing impulse from B closes contact 32 at A; the relay R<1> remains energized by its holding circuit over the switch S', on the starting signal lever, and contact 35. A circuit may also be completed over contact 32, contact 36 of relay R<1>, contact 33 closed by the insertion of staff in the magazine and contact K' on the signal lever to the lock L<1> by which the signal is released. The pulling of the lever opens switch S<1> and relay R<1> is de-energized breaking this circuit at contact 36. The relay R<1> is not energized until switch 30 closes contact 31 as the train leaves the section but since contact 32 is then open the lever cannot again be released. At station B the relay R<2> is normally energized over a switch 44 and the plunger-lock magnet L<2> may be energized by closing switch K<2>. Operation of the plunger opens switch 44 and relay R<2> can only ba re-energized when one of the switches 47, 49 is closed by insertion of the key-ticket or the staff in the magazine. Pulling the home signal lever opens switch S<2> and prevents release of the plunger lock L<2>.
