摘要

An electronic device for producing intermittent flashes according to the rhythm of the music, especially for the interior of automobiles, essentially comprising a casing placed next to a musical device installed in the vehicle in combination with incandescent lamps of different colors that are distributed by the inside the car in suitable areas so as not to produce glare to the driver; and for understanding a circuit composed of a negative pole connected to the loudspeaker of the musical apparatus; an active pole of such an apparatus and that a limiting resistance of maximum legal input is also connected to the loudspeaker; a sensitivity regulator potentiometer; a first coupling capacitor; a polarization resistance; a collector resistance; a first transistor imitator amplifier; a frequency impedance capacitor; a second coupling capacitor; an enclave resistor of an excitation transistor; an adjustable resistance of sensitivity; a power output transistor; a battery position shot; a negative battery socket; a connection of excitation of lights and a common connection of excitation of lights, working the circuit in such a way that enters the negative and active poles enters alternating current or of audio frequency and so that the first mentioned resistance imitates the maximum signal that excites the first limited preamplifier transistor; the sensitivity regulator potentiometer doses the current entering said first transistor; the second coupling capacitor galvanically isolates the base of said transistor and allows the audio component to pass to the base of such a transistor, also allowing direct polarization of the emitting base diode of the aforesaid transistor which amplifies the signal entering through its base and in overexcitation conditions limits the maximum value of said amplified signal present in its collector; the polarization resistance of the polarization of the base of said transistor and determines its working point and together with the collector resistance, through the polarization resistance, a continuous feedback is given that allows the stability of the working point of the transistor ; the collector resistance is on which will appear the audio frequency amplified by the first transistor, whose elements together with the frequency limiting capacitor form a time constant that will limit the maximum frequency at which the device will be sensitive, whose capacitor limits the maximum frequency that will excite the lamps, the second coupling capacitor performing the same function as the first, but with respect to the first transistor preamplifier and the excitation transistor and helping to maintain an inverse polarization of the excitation transistor, in case of a second strong; the enclave resistance of the excitation transistor maintains in base resting conditions of said transistor at zero potential and, peace in giving you, and regulates fast discharge of the second coupling capacitor in operating conditions with serial, whose transistor amplifier amplifies the present in its base and energizes the power output transistor through the resistor that limits the maximum current that passes through the base emitter circuit of the power output transistor, emitter collector of the excitation transistor, allowing the adjustable resistance of the transistor. Sensitivity compensate the gain dispersions of the components of the circuit and especially the power output transistor that amplifies its emitter-base current determined by the adjustable sensitivity resistance and by the excitation transistor, at a level sufficient for the excitation of the incandescent lamps.
