    Abstract: An electro-mechanical-audio converter and an electro-mechanical-audio converting device using the same employed in mobile terminals such as mobile phones for generating paging vibration which realizes stable vibration function. The electro-mechanical-audio converter includes a housing (1a), movable part (2), forming a magnetic circuit, mounted on an opening of the housing (1a) through a suspension (3); and a detection coil (11) disposed near the movable part (2) for generating excitation voltage by vibration of the movable part (2). Strong vibration of the movable part (2) during resonance is detected by the detection coil (11) as an excitation voltage, and fed back. Accordingly, the electro-mechanical-audio converter and electro-mechanical-audio converting device using the same having an extremely stable vibration function, even when resonance frequency changes due to environmental changes such as ambient temperature, is made feasible.

    Abstract: A method and system employing a feedback signal indicative of monitored motion of an electro-mechanical acoustic transducer to generate one or both of a control signal for driving the transducer at its natural resonance frequency, and a warning signal indicating that the transducer is not vibrating at a frequency within a selected frequency range. In preferred embodiments, the transducer is a voice coil loudspeaker mounted in or on a vehicle. In other preferred embodiments, the electro-mechanical transducer is driven by an initial electrical pulse followed by a sequence of electrical pulses. A feedback signal indicative of monitored motion of a moving portion of the transducer is generated. Each pulse (following the initial pulse) is applied at a time (determined by the feedback signal) so as to drive the transducer at its actual natural resonance frequency. Some embodiments monitor the peak velocity (rather than displacement) of a driven electro-mechanical transducer, process the monitored peak velocity signal to generate feedback indicative of actual radiated energy from the transducer, and generate from the feedback signal one or both of a control signal for driving the transducer in a desired manner and a warning signal indicating that the transducer has not radiated a selected minimum amount of energy.

    Abstract: There is disclosed a constant amplitude controller with feedback control for a vibratory feeder apparatus wherein a controlled rectifier is used to rectify the A.C. line voltage applied to the feeder solenoid and to control the voltage to the feeder solenoid. Triggering of the controlled rectifier is accomplished by a bias control signal which is composed of an A.C. phase shift voltage superpositioned by a variable D.C. bias voltage. Mechanical coupling is provided between the solenoid and a transducer which provides feedback to control logic circuitry. In the control logic circuitry, the signal received from the transducer is compared with a signal received from an operator adjusted potentiometer. In this manner, the desired amplitude of the vibrator apparatus is compared with the actual amplitude of the vibrator apparatus and, if there is a discrepancy, the control logic circuitry modifies the amount of control voltage being transferred by the controlled rectifier.

A sensor (110) is provided between the mechanical soniferous apparatus (112) and the oscillating circuit (102). An on-off ratio adjusting circuit (108) is provided at the input end of the oscillating circuit (102). The sensor (110) measures the oscillation frequency of the mechanical soniferous apparatus (112) and feedbacks the measured oscillation frequency signal to the oscillating circuit (102). The on-off ratio adjusting circuit (108) controls a pulse width of an oscillation signal from the oscillating circuit (102) based on a voltage of power supply and/or an ambient temperature. The oscillating circuit (102) outputs corresponding oscillation signal to the driver circuit (104) based on the oscillation frequency signal received from the sensor (110) and/or the control signal from the on-off ratio adjusting circuit (108).
