Abstract
The utility model is a simulating mechanical type electronic horn, comprising a horn, a non contact point control circuit, a synchronous circuit, a simulation circuit, a time base circuit, etc. The simulating mechanical type electronic horn is characterized in that: the signal output terminals of the synchronous circuit and the simulation circuit are connected with the signal input terminal of the time base circuit; the control terminal of the synchronous circuit is connected with the control terminal of the time base circuit; the output terminal of the time base circuit is connected with an electromagnetic coil in the horn by the non contact point control circuit. The characteristic that an electronic line simulates a mechanical horn is used by the utility model. When the natural frequency of a mechanical vibrating system is changed, a synchronous signal is also correspondingly changed, and an output signal always keeps synchronous with the natural frequency of the mechanical vibrating system. The simulating mechanical type electronic horn follows the change of a mechanical characteristic, and simulates and exceeds the environmental adaptability of a mechanical horn. A signal which is provided with the same on-off ratio of the mechanical horn can be generated by the simulation circuit.
Description
Technical field: the utility model belongs to a kind of vehicular horn, specifically is a kind of imitative mechanical electronic loudspeaker.
Background technology: at present, automobile horn has two kinds, mechanical horn and electronic horn, the on off operating mode of mechanical contact is controlled by the mechanical vibrating system of loudspeaker in the mechanical horn, when the resonance frequency of mechanical vibrating system changed because of environmental change, the on off operating mode of mechanical contact also should have certain change mutually.Therefore, mechanical horn has certain environmental suitability, promptly when changes in environmental conditions (temperature, air pressure etc.), also can send the more stable caution sound of sound level, and therefore, up to the present the mechanical type loudspeaker still use in automobile industry in a large number; In addition, the break-make ratio of mechanical horn contact is generally about 2: 1, and this ratio remains unchanged in the course of the work, thereby sound effect is good.But the mechanical contact life-span of mechanical horn inside is very short, poor durability.Its life-span is only at tens0000 times.In addition, after the long-term work, the contactor gap of mechanical type loudspeaker can change, thereby causes sound level to reduce and faults such as dodgoing.Though the electronic horn life-span is longer, follow-up capability is relatively poor, and when environment change, the mechanical property of loudspeaker changes, and electronic circuit is constant, so sound effect is bad.
Summary of the invention: the purpose of this utility model provides a kind of operating characteristic of simulating mechanical horn, both kept and strengthened mechanical horn good environmental adaptability, advantage that follow-up capability is strong, also overcome the imitative mechanical electronic loudspeaker of short shortcoming of mechanical horn life-span simultaneously.The technical solution of the utility model is: the utility model comprises loudspeaker, non-contact control circuit, synchronizing circuit, artificial circuit, time base circuit etc., it is characterized in that: the signal output part of synchronizing circuit, artificial circuit connects the signal input part of time base circuit, the control end of the control termination time base circuit of synchronizing circuit, the output terminal of time base circuit joins by the solenoid in non-contact control circuit and the loudspeaker.The utility model utilizes electronic circuit simulation mechanical horn characteristic, when the mechanical vibrating system natural frequency changes, the also corresponding change of synchronizing signal, make output signal always keep synchronous with the mechanical vibrating system natural frequency, follow the variation of mechanical property, simulated and surpassed the environmental suitability of mechanical horn.Pass through artificial circuit, can produce and have the identical signal of mechanical type loudspeaker make-to-break ratio, because the contactless control loop that high-power FET T constitutes does not have mechanical loss, so its life-span is far longer than mechanical horn, through practical measurement, can reach more than 300000 times its highest serviceable life.
Description of drawings: Fig. 1 is the utility model circuit diagram
Embodiment: the utility model comprises loudspeaker, non-contact control circuit, synchronizing circuit, artificial circuit, time base circuit etc., the signal output part of synchronizing circuit, artificial circuit connects the signal input part of time base circuit, the control end of the control termination time base circuit of synchronizing circuit, the output terminal of time base circuit joins by the solenoid in non-contact control circuit and the loudspeaker.Synchronizing circuit by sensor with resistance R 2 and be connected in series R1 after connecting and form, sensor is placed near the loudspeaker, time base circuit is selected the 555IC sheet for use, artificial circuit is by resistance R 3, R4, R5, R6, diode D1, D2 and capacitor C 1, C2 constitutes, R4 wherein, R5 is connected in series DI respectively, D2 back in parallel again serial connection R3, R6, C1, C2, be used to produce and have the identical signal of mechanical type loudspeaker make-to-break ratio, non-contact control circuit is to be made of high-power FET T and capacitor C 4, C4 is connected in parallel on the output terminal of T, during loudspeaker work, sensor S feeds back to 2 of time base circuit with mechanical oscillation signal, 6 ends, produce the synchronizing signal consistent, 2 of the time base circuit that is added to mechanical vibration performance, 6 ends.Therefore, the change in voltage of 2,6 ends of IC, be controlled by this synchronizing signal, when the mechanical vibrating system natural frequency changed, the also corresponding change of synchronizing signal was by 2,6 ends, the output signal of 3 ends of control time base circuit, make output signal always keep synchronous with the mechanical vibrating system natural frequency, this system has followed the variation of mechanical property, simulates and surpassed the environmental suitability of mechanical horn.7 pin (control end) of time base circuit time base circuit are being controlled the charging and the discharge of charging and discharging circuit, when 7 pin of basic circuit are high level at that time, and the charging of RC loop; When 7 pin of basic circuit are low level at that time, the discharge of RC loop; Between the electric capacity charge period, electric current is through D2, R5, R6 circulation; During capacitor discharge, electric current is through D1, R4, R6 circulation; Adjust the resistance value ratio of R4, R5, just can make time base circuit produce the signal identical with the mechanical horn make-to-break ratio.Non-contact control circuit is to be made of high-power FET T and capacitor C 4, and 3 pin of time base circuit are control signal output ends, are controlling the break-make of high-power FET T, and the superpotential of capacitor C 4 in can absorption circuit prevents to puncture high-power FET T.Because the contactless control loop that high-power FET T constitutes does not have mechanical loss, thus its life-span be far longer than mechanical horn, through practical measurement, can reach more than 300000 times its highest serviceable life.
