Abstract
The utility model relates to an air horn comprising a loudspeaker, a membrane fixing disk, a membrane fixing cover, a membrane and an air flow pipe, wherein a pronunciation cavity is arranged between the membrane fixing disk and the membrane fixing cover, the tail end of the loudspeaker is extended into the pronunciation cavity, one end of the air flow pipe is connected with the pronunciation cavity, the membrane is arranged between the membrane fixing cover and the membrane fixing disk, the membrane, the membrane fixing disk and the membrane fixing cover are fixedly connected via screws, and fixing glue is arranged among the two side faces of the periphery of the membrane, the membrane fixing disk and the membrane fixing cover. The utility model utilizes the technical scheme to provide an air horn capable of preventing air flow leakage so as to guarantee the normal pronunciation thereof.
Description
Technical field
The utility model relates to the loudspeaker field, particularly a kind of air horn.
Background technology
At present; Existing air horn has generally comprised trumpet projector, diaphragm shaft collar, diaphragm fixed cap, diaphragm, and the diaphragm shaft collar is connected with diaphragm fixed cap buckle, is provided with the pronunciation chamber between diaphragm shaft collar and the diaphragm fixed cap; Pressing diaphragm is located between diaphragm shaft collar and the diaphragm fixed cap; The trumpet projector end extends in the pronunciation chamber, also includes gas flow tube, gas flow tube one end and pronunciation chamber conducting.
But the air horn of this structure is because diaphragm directly is pressed between diaphragm shaft collar and the diaphragm fixed cap; And the diaphragm shaft collar is connected with diaphragm fixed cap buckle; Therefore, the part air-flow can be revealed between diaphragm and diaphragm shaft collar, diaphragm fixed cap, makes that air horn can not normal articulation.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of prior art, the utility model provides a kind of air horn, can prevent the air-flow leakage, thereby can guarantee its normal articulation.
The technical scheme of the utility model: a kind of air horn; Include trumpet projector, diaphragm shaft collar, diaphragm fixed cap, diaphragm, gas flow tube; Be provided with the pronunciation chamber between described diaphragm shaft collar and the diaphragm fixed cap; The trumpet projector end extends in the pronunciation chamber, and gas flow tube one end is communicated with the pronunciation chamber, and diaphragm arrangement is between diaphragm fixed cap and diaphragm shaft collar; Described diaphragm, diaphragm shaft collar are connected through screw retention with the diaphragm fixed cap, are provided with fixing glue between described diaphragm periphery two sides and diaphragm shaft collar, the diaphragm fixed cap.
Adopt technique scheme, described diaphragm, diaphragm shaft collar are fixedly connected with diaphragm fixed cap screw, make to be connected reliably between diaphragm and diaphragm shaft collar, the diaphragm fixed cap that sealing property is improved; Be provided with fixing glue between diaphragm periphery two sides and diaphragm shaft collar, the diaphragm fixed cap, further improved the sealing property between diaphragm and diaphragm shaft collar, the diaphragm fixed cap, can prevent the air-flow leakage well, thereby can guarantee its normal articulation.
The further setting of the utility model: air horn also includes mounting bracket, and described mounting bracket includes fore-stock, after-poppet, and described fore-stock is set on the trumpet projector, and described after-poppet and diaphragm shaft collar are wholely set.
Adopt above-mentioned further setting, mounting bracket is set, can make things convenient for the installation of air horn; Mounting bracket is set to fore-stock, after-poppet can be so that air horn installation balance be good.
Further being provided with again of the utility model: described fore-stock include base, with the sleeve that base is wholely set, described trumpet projector is located in the sleeve, is provided with rubber ring between described sleeve lining and the trumpet projector outer wall.
Adopt above-mentioned further setting again,, make and can not slide relatively between fore-stock and the trumpet projector, thereby make that the installation of air horn is more stable owing to be provided with rubber ring between sleeve lining and the trumpet projector outer wall.
