Abstract
The utility model relates to a motor vehicle horn. The motor vehicle horn comprises a fixed iron core, electromagnetic coils and movable iron. The movable iron and the fixed iron core are coaxial. The electromagnetic coils are placed on the periphery of the movable iron and the periphery of the fixed iron core, wherein the length of the fixed iron core is in accordance with the height of a coil frame. The lengthened part of the fixed iron core is used for heat dissipation of the horn coils, and the defect that the horn may be damaged due to the fact that the plastic electromagnetic coil frame inside the horn is partly melted and deformed at the excessive temperature during honking of the horn for a long time is overcome.
Description
Technical field
The utility model relates to a kind of electric horn of motor vehicle.
Background technology
That generally uses on the current mobility car has mechanical type electric horn, electronic type electric horn and a computermatic electric horn.Along with the raising of international standard, require the loudspeaker time that pipes continuously also to lengthen more than 3 times, reach 10 minutes.Fig. 2 has illustrated a kind of sectional view of prior art loudspeaker.As seen from the figure, loudspeaker fixed core 23 is equivalent to about 1/2nd height of coil former, and moving iron 21 moves reciprocatingly and drives the diaphragm vibration, thereby sounds.But the high temperature that coil produced when loudspeaker piped for a long time can make coil former inwardly dissolve distortion (referring to the part of label 24), causes the moving iron core of loudspeaker to be clamped and causes loudspeaker to damage by normal articulation.
The utility model content
The purpose of this utility model is to propose the loudspeaker that can address the above problem.
For this reason, the utility model provides a kind of loudspeaker.These loudspeaker comprise fixed core, solenoid and moving iron; Moving iron and fixed core are coaxial, solenoid place fixed core around; Wherein, fixed core length and coil former height basically identical.
Be horn coil heat radiation with the fixed core elongated portion, prevented effectively when loudspeaker from piping for a long time that plastics solenoid frame dissolves the disadvantage that distortion causes loudspeaker to damage because of the too high part of temperature rise in the loudspeaker.
Description of drawings
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Fig. 1 has illustrated a kind of sectional view of the utility model embodiment loudspeaker;
Fig. 2 has illustrated a kind of sectional view of prior art loudspeaker.
Embodiment
The utility model relates to the method with the horn of motor vehicle that lengthens fixed core, be horn coil heat radiation with the fixed core elongated portion, prevented effectively when loudspeaker from piping for a long time that plastics solenoid frame dissolves the disadvantage that distortion causes loudspeaker to damage because of the too high part of temperature rise in the loudspeaker.
Fig. 1 is the cut-open view according to loudspeaker of the present utility model.As shown in Figure 1, loudspeaker comprise base, diaphragm, solenoid, moving iron core 1 and fixed core 3.Diaphragm is fixed between base and the resonator shell, moving iron 1 and fixed core 3 coaxial placing in the described shell.One end that should move iron 1 is connected with described diaphragm is central.One end of fixed core is provided with screw rod and passes the axle center hole of base, solenoid place fixed core around (referring to skeleton 2).
In operation, the alternating magnetic field of solenoid generation drives moving iron core to-and-fro movement.Moving iron core drives the diaphragm vibration, thereby sounds.
In embodiment of the present utility model, fixed core added grow to and the essentially identical height of horn coil frame.The high temperature that coil produces when loudspeaker pipe for a long time dispels the heat by fixed core, thereby can make the temperature rise of coil former not reach the temperature of inwardly dissolving distortion.And, even coil former is because high temperature dissolves distortion, because moving not to-and-fro movement in coil former of iron core just can not influence the work of moving iron core, thereby guaranteed that the high temperature that loudspeaker can coil produce when piping for a long time makes coil former inwardly dissolve the phenomenon that distortion causes loudspeaker to damage.
Can be used for all kinds of motor vehicles, boats and ships or similar devices according to loudspeaker of the present utility model.
Above-described embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is embodiment of the present utility model; and be not used in and limit protection domain of the present utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
