Abstract: An electric sound producing device includes a ferromagnetic diaphragm, an electromagnet for deforming the diaphragm and an oscillator for repeatedly supplying short duration current pulses to the electromagnets. The oscillator may be driven by a multivibrator to produce intermittent sound pulses or by a sawtooth pulse generator to produce sound with an apparently cyclically varying frequency.

Abstract: A sound wave generator includes a speaker control circuit and a speaker. The speaker control circuit includes a signal generating unit that is configured to generate an electric signal having a humming frequency property. The humming frequency property includes a plurality of frequencies that have an overtone relationship with respect to A Hz and are pitched at the A Hz, the A Hz being a target generation frequency and corresponding to a low pitch frequency in an audible range. The speaker generates a sound wave from the electric signal by applying the electric signal to a vibration plate that produces the sound wave.

Abstract: A mobile terminal with an electromagnetic actuator for generating speech, buzzing sound, or low-frequency vibration. The mobile terminal generates little abnormal sound. In this electromagnetic actuator, the terminal lugs are short-circuited, the terminal lugs are electrically connected to amplifiers, or an amplifier is electrically connected to a signal generator for generating a constant-voltage signal or a constant-frequency signal. In such a way, the abnormal sound caused by the vibration of a mechanical vibration system of the actuator is reduced.

Abstract: Adjustment of the pulse energizing frequency and duty cycle of a vehicle horn (60) is described. The horn is blown by a test energizing circuit (102) with a varying pulse frequency and the frequency at which the horn produces the maximum sound pressure level is taken as the predetermined resonant frequency. Then the horn is blown by the test energizing circuit at the resonant frequency with a varying duty cycle and the value of duty cycle which produces a predetermined striking force of the plunger (16, 16') against the pole piece (22, 22') is taken as the predetermined impact-producing duty cycle which is used for setting the operating duty cycle of the horn in a manner depending upon the type of the horn. The horn is then blown by its own electronic energizing circuit (100) and the actual pulse frequency thereof is adjusted, preferably by laser trimming of a resistor (86), to match the resonant frequency. The horn is blown by its own energizing circuit at the resonant frequency and the duty cycle is adjusted.
