Abstract
The utility model provides an annular contactless automotive electronic horn. The conventional contactless electronic horn is characterized in that an electronic circuit is used for oscillating control of a sounding system and thus enables the horn to make a sound. The electronic circuit has the disadvantages of complex structure, multiple circuit components, high development cost and material cost, relatively complicated manufacturing process, and relatively high equipment cost and tool cost. The annular contactless automotive electronic horn comprises a horn shell; an annular support is installed in the horn shell; a group of static iron cores are installed on the annular support in the circumferential direction; the center of the annular support is provided with a rotary power supply connector; each static iron core is wound with a magnetic coil which is provided with a power connection connector; the annular support is provided with guide rails corresponding to the static iron cores in a one-to-one manner; movable iron cores are installed on the guide rails and are connected with membranes; and the two ends of each membrane are fixed to the matched guide rail. The utility model provides the automotive horn facility.
Description
Technical field:
The utility model relates to a kind of automobile electronic loudspeaker, is specifically related to the contactless automobile electronic loudspeaker of a kind of annular.
Background technology:
Car horn is divided into two kinds of electric horn and air horns, and electric horn, by constantly energising and outage of solenoid, makes metallic membrane produce vibration and produce sound equipment, and sound is melodious.Mostly the electric horn profile is spirality and basin shape, is widely used on various automobiles.Modal disc type horn is riveted together by shell fragment, insulation spacer, steel disc, then rivets respectively two very little upper tungsten points and lower tungsten point on steel disc and shell fragment.By contact and the disconnection of two contacts, realize the break-make of circuit, drive the diaphragm vibration, make sound horn.The mechanical horn poor stability of this hard contact, life-span are low, complex structure.In addition, the material requirements that use contact is high temperature resistant, corrosion-resistant, and price.Make the manufacture method of its loudspeaker complicated, the workshop management expense is high.Productive temp is more, and rhythm of production is slower, location is installed easily produces error, produces unacceptable product.
The mechanical horn that contact is arranged in existing automobile horn is that the break-make by contact drives having or not of solenoid current, thereby produce electromagnetic force, drives the diaphragm vibration and sounding.Due to a larger electric current being arranged through contact, when disconnecting again, the solenoid contact produces very high induced voltage, puncture air and the ablation contact, the contact of ablation is easy to oxidation, thereby the contact contact resistance is increased, make circuit obstructed, thereby loudspeaker were lost efficacy.Thereby this loudspeaker are very high to the requirement of contact, and a lot of producers even use the platinum contact, but, still over time by the large electric current ablation of circuit, make contact oxidation, and the life-span of loudspeaker is reduced greatly, can not reach client's requirement.
Existing contactless electronic loudspeaker is controlled sonification system with an electronic circuit vibration and is made sound horn, this electric circuit construction is complicated, and the circuit elements device is many, and its cost of development and material cost are high, manufacturing process is more complicated also, and equipment cost and frock cost are also higher.
Summary of the invention:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of annular contactless automobile electronic loudspeaker, and circuit is simple, components and parts are few, manufacturing process is simple, the life-span is long.
Above-mentioned purpose realizes by following technical scheme:
The contactless automobile electronic loudspeaker of annular, comprise the loudspeaker housing, ring support is installed in described loudspeaker housing the inside, described ring support is along one group of static iron core circumferentially is installed, the center of described ring support is installed and is rotated power supply connector, be wound with magnetic coil on each described static iron core, has power connection on described magnetic coil, the position mounting guide rail of corresponding each static iron core on described ring support, moving iron core is installed on described guide rail, described moving iron core connects diaphragm, and the two ends of described diaphragm are fixed on described guide rail.
The contactless automobile electronic loudspeaker of described annular, described rotation power supply connector comprises power supply, described power supply connects respectively CD-ROM drive motor and electric conductor, described CD-ROM drive motor connection rotating shaft, described electric conductor is arranged in described rotating shaft.
The contactless automobile electronic loudspeaker of described annular, described power connection and described electric conductor are in the same plane.
Beneficial effect:
1. the utility model adopts the electric conductor of power supply connection of rotating, in the process that electric conductor rotates successively with the power connection conducting that is arranged on the coil on the circle of one on ring support static iron core, static iron core attracts moving iron core motion, when electric conductor is rotated further the power connection that leaves the coil on corresponding circle static iron core, corresponding moving iron core resets, and moving iron core is with the dynamic diaphragm vibrations so repeatedly, makes the diaphragm sounding, the good stability of loudspeaker, extended serviceable life.
2. in order to guarantee that power connection can contact smoothly with electric conductor, power connection of the present utility model and electric conductor are in the same plane.
