Abstract
The utility model relates to a sounding instrument, particularly an electric horn which can prevent and limit the displacement and the deformation of a diaphragm of the horn. The electric horn comprises a coil, a circuit board, the diaphragm, a shaft and a casing, and an elastic damping and resetting member is arranged between the diaphragm and the casing. The utility model has the following advantages that when the diaphragm makes the reciprocating movement every time, the diaphragm can come back to the fixed position; fatigue deformation can not be generated after the diaphragm is strongly vibrated every time; the diaphragm has the stable position to ensure sounding frequency; the displacement of the diaphragm is efficiently prevented simultaneously; the service life of the horn is largely enhanced; a method is simple and reliable.
Description
One, technical field
The utility model relates to a kind of sound equipment, specifically, is a kind of electric horn that prevents, limits loudspeaker diaphragm displacement and distortion that has.
Two, background technology
Common electric horn generally divides mechanical contact common electrical loudspeaker and common contactless electron electric horn at present, wherein there is following shortcoming in common electrical loudspeaker (being mechanical contact-type): 1, the electromagnetism that closes, closes generation because of the contact involves spark and disturbs, electric spark can corrode the contact, also has contact meeting mechanical wear, oxidation; 2, the electric spark of contact generation can produce stronger electromagnetic wave, and this Electromagnetic Interference is very capable, can destroy other electronic equipment and surrounding enviroment on the automobile; 3, the contact need consume a large amount of precious metal materials.Though common contactless electron electric horn has replaced the contact with electronic switching circuit, eliminated the drawback of contact, it can't meet the requirements well in fact, the performance of electric horn is improved, make electric horn become that life-span length, reliable operation, tonequality are good, the electric horn of freedom from repairs veritably, also will improve; The problem of the mechanical shift of loudspeaker diaphragm and distortion particularly.
Three, summary of the invention
The purpose of this utility model is to provide a kind of electric horn that prevents, limits loudspeaker diaphragm displacement and distortion that has.
For achieving the above object, the utility model adopts following technical scheme: it comprises coil, circuit board, diaphragm, diaphragm axle and housing, is provided with elastic damping, return unit between diaphragm and the housing.Above-mentioned elastic damping, return unit are spring, and elastic damping, return unit one end are located on the housing, and the other end is located on diaphragm or the diaphragm axle.
The utility model compared with prior art has following advantage: during the each to-and-fro movement of diaphragm, it can both get back to fixing position, does not produce fatigue deformation after making the each strong amplitude of diaphragm, makes diaphragm have stable position to guarantee pronouncing frequency; Simultaneously prevent diaphragm displacement effectively, in the serviceable life of significantly improving loudspeaker, method is simple, reliable.
Four, description of drawings
Accompanying drawing is the utility model structural representation.
Five, embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, as shown in the figure: this electric horn comprises coil (2), circuit board (3), diaphragm (4), diaphragm axle (1) and housing (5), diaphragm (4), diaphragm axle (1) are connected as a single entity, be provided with spring (6) between diaphragm (4) and the housing (5), spring (6) one ends are located on the housing (5), and the other end is located on the diaphragm axle (1).
Claims (3)
1, a kind of have an electric horn that prevents, limits loudspeaker diaphragm displacement and distortion, and it comprises coil, circuit board, diaphragm, diaphragm axle and housing, it is characterized in that: be provided with elastic damping, return unit (6) between diaphragm (4) and the housing (5).
2, according to claim 1 have an electric horn that prevents, limits loudspeaker diaphragm displacement and distortion, and it is characterized in that: elastic damping, return unit (6) are spring.
3, according to claim 1 and 2 have an electric horn that prevents, limits loudspeaker diaphragm displacement and distortion, and it is characterized in that: elastic damping, return unit (6) one ends are located on the housing (5), and the other end is located on diaphragm (4) or the diaphragm axle (1).
