Abstract
The utility model relates to an electric horn frequency coordination control device, which comprises a moving iron core, an electromagnet, and an optoelectronic coupler connected with an electronic circuit. The optoelectronic coupling controls the on-off of the electromagnet through the electronic circuit. A luminous part and a receiving part which constitute the optoelectronic coupler are arranged in a working chamber. A light cover plate linked with the moving iron core is matched with the optoelectronic coupler. One end of the light cover plate is inserted in the working chamber between the luminous part and the receiving part, and the other end of the light cover plate is fixed on a base plate. A cap liner is arranged on the insertion opening of the light cover plate of the working chamber. The working chamber is integrated with the base plate. The electric horn frequency coordination control device overwhelms the defects of the ordinary electric horn that the frequency of electronic signal is not in line with the oscillation frequency of a tibial membrane, and the Hall technology is subject to the inference of the electromagnetic field. Through the design, the electronic circuit can be compatible with a mechanical articulatory system in different use environments so that resonance frequency is resonant. The utility model has the advantages of simple and compact structure, high capacity of resisting disturbance, high reliability and low cost.
Description
Technical field
The utility model relates to a kind of electric horn frequency coordination control device.
Background technology
Existing contactless loudspeaker are the electric oscillation signals that utilize electronic technology to produce, and the diaphragm that is used for driving sonification system sends the sound, and when the oscillation frequency of electrical signal frequency and pronunciation diaphragm was harmonious, loudspeaker sent the satisfactory sound.In the back of dispatching from the factory because external environment condition or articulatory system mechanical property when changing, all can cause the two frequency inconsistent and influence voice effect.Along with the application of hall device in electronic horn, changed the above-mentioned shortcoming of electronic horn, but respond to and come control circuit because the Hall technology is an applied magnetic, the long-term vibration use of magnet can make magnetic weaken, and because complicated factors such as the interference that generates an electromagnetic field after the electromagnet energising influence the operate as normal of Hall element.
Summary of the invention
In order to overcome the problems referred to above of prior art, the utility model provides a kind of electric horn frequency coordination control device, simple and compact for structure, the antijamming capability of this electric horn frequency coordination control device is strong, long service life, with low cost, reliability is high.
The technical scheme that its technical matters that solves the utility model adopts is: comprise moving iron core, electromagnet and the photoelectrical coupler that links to each other with electronic circuit, photoelectrical coupler is by the break-make of electronic circuit control electromagnet, the illuminating part of composition photoelectrical coupler and the lid mating plate that receiving element is arranged in the working chamber and moving iron core links match with photoelectrical coupler.
In the one end insertion illuminating part and the working chamber between the receiving element of lid mating plate, the other end is fixed on the pedestal.
The lid mating plate of working chamber inserts mouth and is provided with cap liner.
Working chamber and pedestal fuse.
One side of lid mating plate forms flange and moving iron core is linked.
The utility model is by above-mentioned specific design, utilize light, electric coupling to control the electronic circuit oscillation frequency, its coupling frequency derives from vibrating diaphragm, so and articulatory system can reach on all four association vibration frequency, when under the varying environment condition, using, can both make association's vibration frequency sympathetic response, make the loudspeaker pronunciation reach the best sound all the time, have that antijamming capability is strong, a long service life, simple and compact for structure, advantage that reliability is high, with low cost.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cut-open view of Fig. 1.
Embodiment
As shown in the figure, the utility model comprises moving iron core 1, electromagnet 2 and the photoelectrical coupler that links to each other with electronic circuit 3, photoelectrical coupler is by the break-make of electronic circuit 3 control electromagnet 2, illuminating part 4 and the receiving element 5 of forming photoelectrical coupler are arranged in the working chamber 6, match with photoelectrical coupler with the lid mating plate 7 of moving iron core 1 interlock, above-mentioned linkage structure can be that the side formation flange 9 that covers mating plate 7 is linked with moving iron core 1, also can be the intermediate connector interlock that other is set between moving iron core 1 and lid mating plate 7.In the one end insertion illuminating part 4 and the working chamber 6 between the receiving element 5 of lid mating plate 7, the other end is fixed on the pedestal 10, and lid mating plate 7 is made by resilient material possesses autonomous reset function, also can dispose in addition to make and cover the elastic component that mating plate 7 resets.Working chamber 6 fuses with pedestal 10.The lid mating plate 7 of working chamber 6 inserts mouth and is provided with cap liner 8.When working power is connected, connect electromagnet 2 generation pulsating fields through electronic circuit 3 and make iron core 1 adhesive, this moment, the lid mating plate 7 with moving iron core 1 interlock moved, and the light source between the photoelectrical coupler illuminating part 4 that blocked (or open) and the receiving element 5, this moment, photoelectrical coupler cut off the power supply of 3 pairs of electromagnet 2 of electronic circuit, moving iron core 1 is along with the resilience of vibration pronunciation diaphragm, lid mating plate 7 counteragent under elastic reaction, the light source of having opened (or blocking) between photoelectrical coupler illuminating part 4 and the receiving element 5, electronic circuit 3 recloses the working power of electromagnet 2, so that moving iron core 1 adhesive.So go round and begin again and serve as the vibration elementary sources, make between electronic circuit and the mechanical articulatory system and coordinate, and make association's vibration frequency sympathetic response, send desirable voice effect with the particular amplitude frequency of pronunciation diaphragm.
