Title: Improvements in or relating to electromechanical transducers
IPC: H04R23/00
Filed: 1965-02-26
Abstract: 1,074,822. Pressure transducers. SIEMENS A.G. Feb. 26, 1965 [Feb. 28, 1964], No. 8329/65. Heading H1K. [Also in Division H4] A pressure transducer comprises a semiconductor device constructed as a field effect transistor, with at least one hard stylus mounted so as to bear on the body and thus influence the source drain current in operation. In an NPN planar device (Fig. 1, not shown) the source and drain connections are made to opposite ends of the P region and the stylus bears on the surface N zone. Increase in pressure is associated with an increase in source drain current if the stylus is near the drain and with a decrease if it is near the source. For an approximately central position of the stylus the pressure-current characteristic is unchanged if the source and drain connections are interchanged. The gate control electrode provided on the main body may if desired be dispensed with. Similar effects are obtained by applying pressure via a stylus to the channel of a MOS transistor. In another arrangement, Fig. 2, the channel of the field effect device constitutes a resistor in the base-collector circuit of a planar transistor formed by zones 12, 13, 14. The channel is the section of zone 13 underlying the strip form N-type zone 19 better seen in Fig. 3 (not shown). Additional styli 17, 18 may be provided adjacent the emitter and collector junctions to enable modulation effects to be obtained. The arrangements may be used in microphones or in systems for measuring pressure.

As shown in Fig. 2, the ringing mechanism 12 operates a mercury switch mounted on a lever 9 and connected in a circuit 7 which is adapted to operate a warning system of the type described in Specification 436,216, [Group XXXVIII], wherein the ordinary lighting system 2 of a house or other establishment is used to give a warning when a door push button 16 is operated. Operation of the ringing mechanism 12 operates a mercury switch 18 to switch on the lights 3 during the day and vary the illumination by the inclusion of a resistance 4 during the night. The mercury switch 18 comprises a hollow armature 19 which when attracted by the solenoid 6a displaces mercury and establishes electrical contact between the electrodes 26, 27. The armature incorporates a valve 21 and byepass 28<1> which allows mercury to flow back into the armature and break the circuit after a time period in the event of continuous energization of the solenoid. Instead of the mercury switch, an electromagnetically operated two-way switch used in conjunction with a time delay thermostatic switch may be used. The mercury switch associated with the ringing mechanism may be mounted on a pivoted lever provided with a forked end which embraces the bell-hammer. One form of switch is shown in Fig. 5 and comprises a closed vessel 36 containing two pools of mercury 37, 38 which establish con. tinuous electrical contact between the electrodes 371, 38<1> when the switch is vibrated bodily.
