Abstract
The utility model relates to a double-frequency trumpet for ball game fans, which mainly comprises a cylinder body, a drum film and a first blowing nozzle, wherein one end of the cylinder body is provided with an opening, and the other end of the cylinder body is covered with a layer of drum film; the first blowing nozzle is communicated with a first cavity in the cylinder body, and an inner cylinder body is arranged in the cylinder body; a second cavity is formed among the inner cylinder wall of the cylinder body, the outer cylinder wall of the inner cylinder body and the drum film, and a second blowing nozzle is communicated with the second cavity. The utility model has advantages that the utility model can generate two acoustic frequencies with two effects of high pitch and bass, wherein the high pitch acoustic frequency sounds magnificent, saves labor, does not harm the throat and the voice, and is extremely suitable for fans, cheering squads and mass to cheer and make power in large-scale community competitions, such as football competitions, basketball competitions, etc. or sports, parties and march activities; the bass acoustic frequency adopts a traditional blowing nozzle, has moderate sound and is suitable for being used in small items, small fields and small scale competitions. Two acoustic frequencies have different playing effects, and holders can select different frequencies by themselves according to different factors, such as specific fields, atmosphere, etc.
Description
Technical field
The utility model relates to the loudspeaker field, mainly is a kind of double frequency football fan loudspeaker.
Background technology
The long tube single-frequency loudspeaker of common traditional shape, can only produce a kind of audio frequency of audio, it is lighter to pronounce, only be adapted at small project, little place, use in the match on a small scale, football fan, cheering squad and the masses are used for cheering, making a show of power in large-scale group event such as football, basketball or athletic meeting, rally, the parade activity and can not be useful in.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and the big labour-saving of a kind of harmony simple in structure double frequency football fan loudspeaker are provided.
The utility model solves the technical scheme that its technical matters adopts: this double frequency football fan loudspeaker, mainly comprise cylindrical shell, eardrum and first blow gun, described cylindrical shell one end opening, the other end is coated with one deck eardrum, and first cavity in first blow gun and the cylindrical shell is connected; Be provided with inner barrel in the cylindrical shell, form second cavity between the outer tube wall of the inner tube wall of cylindrical shell, inner barrel and eardrum, second blow gun is connected with second cavity.
The effect that the utility model is useful is: these loudspeaker have two blow guns, produce the audio frequency of two different audios of height, and they lay respectively at from the about two centimeters places of loudspeaker both sides nozzle.The pronunciation of its alt audio frequency is grand and extremely laborsavingly can not produce injury to throat, throat, is fit to extremely that football fan, cheering squad and the masses are used for cheering, making a show of power in large-scale group event such as football, basketball or athletic meeting, rally, the parade activity; Audio bass adopts traditional mouthpiece, and sound is moderate, is adapted at small project, little place, uses in the match on a small scale.Two audio frequency are played wind instruments effect, and each is variant, and the person of holding can select according to different factor oneselfs such as concrete place, atmosphere.This horn structure tube list, modern design, principle are clear, sound is laborsaving greatly, smooth surface, and feel is splendid.This product substantially all forms with plastic injection-moulded except that the eardrum that a slice latex is made, and horn integral is single look, can customize the selection shades of colour as required.
