Abstract
The utility model discloses a buglet, which is applied for adding fun. The buglet comprises a megaphone, a phonation cavity, and a diaphragm. Wherein, the principal part of the megaphone is cone-shape. The phonation cavity is arranged at the back-end of the megaphone. The diaphragm is arranged at the back-end of the phonation cavity. A mouthpiece is arranged upon the phonation cavity. A leading tone pipe is arranged at the back-end of the megaphone, and is communicated with the back-end of the megaphone. The leading tone pipe dives into the centre of the phonation cavity, and touches the diaphragm. The diaphragm is a flexible plastic film, which is arranged upon a circular flexible plastic gasket. The flexible plastic gasket is arranged at the back-end of the phonation cavity. The mouthpiece protrudes from the phonation cavity lateral, then bends and extends backwards. Since the biggish diaphragm is arranged at the back-end of the phonation cavity, a fairly good sound production effect will be achieved under the force of the airflow. By means of the amplification effect of the leading tone pipe and the megaphone, a large sound volume will be produced. The sound volume is largely increased.
Description
Technical field
The utility model relates to a kind of air blowing loudspeaker, the air blowing loudspeaker that particularly a kind ofly add to the fun, first aid etc. used.
Background technology
At present, many football fans are that a side cheers on the court, add to the fun, and make the population dry tongue dry sometimes, even throat are cried out mute.So people have just used a kind of toy toy trumpet, this toy trumpet is generally made by plastic material, and the Megaphone of a taper is wherein arranged, and taper Megaphone rear end is provided with vibrating reed, and the air stream drives vibrating reed sounding by directly being blown into is amplified by Megaphone.This toy trumpet is owing to be that straight air stream drives very little vibrating reed sounding, so it is not fine that effect takes place, the volume of sending is limited, and as using in noisy occasion, its effect is unsatisfactory.
The utility model content
The purpose of this utility model is to provide a kind of toy trumpet of adding to the fun, and it is provided with bigger vibrating membrane, and it is good to have sounding effect, the characteristics that give great volume.
The toy trumpet of adding to the fun of the present utility model comprises Megaphone, pronunciation chamber, vibrating membrane, and wherein the Megaphone main body is a cone shape, and the pronunciation chamber is arranged on the rear end of Megaphone, and the rear end in pronunciation chamber is provided with vibrating membrane, and the pronunciation chamber is provided with blowing nozzle.
Above-mentioned described Megaphone rear end is provided with sound guide tube, is communicated with the Megaphone rear end, and sound guide tube extend into pronunciation chamber central authorities and contacts with vibrating membrane.
Above-mentioned described vibrating membrane is flexible plastic film, and this flexibility plastic film is arranged on the annular Elastic plastic-rubber circle, and the Elastic plastic-rubber snare is located at the rear end in pronunciation chamber.
Above-mentioned described blowing nozzle is drawn from pronunciation side, chamber, extends back away after the bending.
Because the utility model is provided with bigger vibrating membrane at pronunciation chamber rear side, has sounding effect preferably under the promotion of air-flow, by the amplification of sound guide tube and Megaphone, can produce very big volume and send out, volume improves greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, of the present utility modelly constitute by Megaphone 8, pronunciation chamber 6 and vibrating membrane 3.Wherein Megaphone 8 is conical hollow open body, and its rear end is connected with hollow cylindrical sound guide tube 4.This cylindrical sound guide tube 4 extend in the pronunciation chamber 6, and make sound guide tube 4 protrude in the rear end in pronunciation chamber 6, and pronunciation chamber 6 also is conical ducted body, the front end in pronunciation chamber 6 is connected with Megaphone is airtight, connected mode among the figure connects by screw thread 7 fixed locks for being threaded.And the rear end in pronunciation chamber 6 is an opening.And the vibrating membrane of being made by the Elastic plastic-rubber film 3 is set on this opening, this vibrating membrane 3 is circular, be arranged on the Elastic plastic-rubber annulus 2 around it, thereby resilient sleeve is located at the tail end in pronunciation chamber 6.At this moment, sound guide tube 4 can make vibrating membrane be in tensioned state the central part of vibrating membrane 3 jack-up slightly.
As shown in the figure, a side in pronunciation chamber 6 is drawn a blowing nozzle 5, and this blowing nozzle 5 is a body that bends backward, extends to the rear side in pronunciation chamber always, so that blow afloat more convenient.
Because vibrating membrane 3 is a plastic material,, do not damage protection vibrating membrane 3 special arranged outside over cap 1 for not being scratched easily at vibrating membrane 3.
The utility model in use, by blowing nozzle 5 air blowing air-flows, air-flow flows in pronunciation chamber 6 backward, because obturation effect, vibrating membrane 3 is moved backward, thereby between sound guide tube 4 and vibrating membrane 3, form gas channel, and then make vibrating membrane 3 vibration soundings, sound sends out by sound guide tube 4 and Megaphone again, and the effect that amplifies of this loudspeaker is relatively good.
