Abstract
A voice speaker for vehicle use comprises an alnico arranged in the cavity surrounded by a lower sizing block and an upper washer. The upper washer is arranged on the conjoint step located at the external rim of the lower sizing block. A circular magnetism gap is formed between the alnico and the cavity. The lower sizing block is cup-shaped and connected with a cooling fin, and the inner side and the lower side of the upper washer is bordered with the two lateral sides of the conjoint step. At the ram effect of the punch, the upper washer and the lower sizing block of the utility model are pieced tightly by pressure welding at the conjoint step of the top external rim of the lower sizing block, diminishing the external dimension of the original upper washer and the flanging part of the original lower sizing block, depressing the consumption of the stuff and reducing the cost on the basis of satisfying the fundamental function of the bugle. This utility is of a simple and reasonable structure, light weight, low cost and good radiating effect.
Description
Technical field
The utility model relates to a kind of automobile-used voice loudspeaker.
Background technology
I disclose a kind of loudspeaker magnetic circuit device in the Chinese patent ZL200420102810.X of application on December 11st, 2004, comprise magnet steel, and magnet steel is arranged in the cavity that is surrounded by lower padding iron and Upper gasket; The lower padding iron cross section is a u shape structure, and Upper gasket is a loop configuration, and Upper gasket covers the lower padding iron surface; Be formed with the annular magnetic gap between magnet steel and the cavity.The position at the corresponding magnetic gap of lower padding iron place is provided with louvre.This loudspeaker magnetic circuit device surrounds a cavity in lower padding iron and Upper gasket, is placed with magnet steel in this cavity, and the position at the corresponding magnetic gap of lower padding iron place is provided with louvre; When the loudspeaker magnetic circuit device was worked, the heat of its generation can be dispersed in the magnetic gap, and directly discharges this device by louvre, reduces this device working temperature conscientiously, raises the efficiency.But the loudspeaker magnetic circuit device volume ratio of this structure is bigger, and integral body is heavier, consumable material is also many, and manufacture craft is also many, and cost is also higher, makes the user not too satisfied.
The utility model content
The purpose of this utility model be to provide a kind of simple and reasonable, overall weight is light, cost of manufacture is low, the automobile-used voice loudspeaker of good heat dissipation effect, to overcome weak point of the prior art.
A kind of automobile-used voice loudspeaker by this purpose design comprise magnet steel, and its architectural feature is that magnet steel is arranged in the cavity that is surrounded by lower padding iron and upper gasket; Upper gasket is arranged on the top outer edge place of lower padding iron; Lower padding iron top outer edge place is provided with the assembly unit step, and upper gasket is crimped on this assembly unit step, is formed with the annular magnetic gap between magnet steel and the cavity.
The cup-shaped structure of above-mentioned lower padding iron, upper gasket medial surface and bottom surface are joined with assembly unit step two sides respectively.
An above-mentioned lower padding iron and a fin join.
Above-mentioned lower padding iron bottom rear is provided with the location short column of butt joint usefulness, and fin is provided with location hole to locating short column, and the location short column is installed in the location hole.
Above-mentioned location short column be two and more than, be symmetrical arranged.
The above-mentioned fin left and right sides is respectively arranged with outstanding installing and locating hole.
Above-mentioned fin one end is provided with outstanding installing and locating plate, and the installing and locating plate is provided with the installing and locating hole.
Above-mentioned upper gasket edge was provided with the line open slot.
Above-mentioned line open slot excessively is two, along circumferentially being provided with.
Upper gasket in the utility model and lower padding iron under the punching press effect of stamping machine, the closely amalgamation after crimping in lower padding iron top outer edge assembly unit step place; Both reduce the overall dimension of original upper gasket, also reduced the flanging part of original lower padding iron, on the basis of satisfying the loudspeaker basic function, reduced the consumption of material, saved cost.
The utility model is in order to obtain better radiating effect, in the lower padding iron bottom fin is set, lower padding iron and fin fit tightly, and the heat that produces when this fin can be worked loudspeaker in time and is effectively taken out of, to reduce the temperature rise in the loudspeaker, prolong the useful life of loudspeaker; In order to guarantee that further fin is connected with lower padding iron reliably, in the lower padding iron bottom location short column is set, location hole is set on fin, the location short column is installed in the location hole, and fin and lower padding iron fit tightly, to guarantee its radiating effect.
The utility model is simple and reasonable, overall weight is light, cost of manufacture is low, good heat dissipation effect.
