Title: Motional feedback system for loudspeakers
Inventor: BIRT DAVID ROBIN
IPC: H04R3/00
Filed: 1986-09-25
Abstract: The system compensates for non-linearity of the BI (gap flux densityxlength of wire within gap) factor in a moving coil motor system of a loudspeaker Memory (PROM) 62 stores digital words, each of which represents an appropriate correction coefficient to be applied to the speech-coil back-EMF at a specific displacement, to provide an accurate linear velocity signal. The PROM is addressed by a digitised displacement-proportional signal 61, and feeds the digital inputs 65 of a multiplying digital-to-analogue converter (MDAC) 66. The output of the MDAC is the product of the PROM correction coefficients and the scaled back-EMF 14 applied to the Reference input 67 of the MDAC. Addition of the analogue signal 71 to the back-EMF in summing amplifier 76 provides a corrected velocity signal 13. Path 14 to 13 completes a negative-feedback loop enclosing the audio power amplifier and loudspeaker. <IMAGE>

Patent GB-2237898-A (GB)
Title: Control by pulse width modulation
Inventor: COOKE STEPHEN JOHN
IPC: G05D16/20
Filed: 1989-10-11
Abstract: The relationship between the duty ratio of drive pulses 15 received by a control device such as a pump 17 to an output parameter such as the resulting pressure in a fluid 5 is often non-linear. In order to compensate for this, and provide a linear relationship between the value of a control signal 11 and the output signal, the function relating the level of the control signal 11 to the duty ratio of the drive pulses 15 is made to be non-linear in a complementary manner. To achieve this, a pulse width modulator 13 compares the control signal 11 with a modified sawtooth waveform having a non-linear upward ramp. The shape of the upward ramp of the sawtooth waveform is modified by providing a Zener diode 41 in the charging network for a capacitor 33 in the oscillator section 19 of the pulse width modulator 13 so that the capacitor charges at successively different rates. <IMAGE>
