Summary of the invention
The purpose of the utility model is to carry out architecture advances existing calling, and makes the air-flow sound-producing device can realize optionally sounding or sounding not, when sounding, can accomplish that selectivity sends the purpose of a certain or a few kinds of sound simultaneously.
To the problem that exists in the present air-flow sound-producing device, the utility model provides a kind of slide sheet type air-flow sound-producing device, comprises sounding control piece, sounding chamber, cries, and said crying comprises gas channel, gas port and be installed on the reed in the gas port; Said sounding control piece and sounding chamber form a sealing or semi-enclosed airflow space; Said sounding control piece is the housing that offers two or more through holes, and said housing comprises pickup groove and chute, said pickup groove and the top card of crying with, card and at least one catch in the said chute, said catch can cover through hole fully.Through the slip of catch in chute, can optionally cover or gas port that exposure place is named, thereby expose the corresponding air-flow of the place's of crying formation of gas port.Gas passes corresponding gas channel, is flowed out by the gas port that exposes, and in this process, triggers reed, thereby produces sound.After in the air-flow sound-producing device, different crying being installed, just can cover the gas port that cries that does not need sounding as required, the sound that one or more need is sent in extruding sounding chamber.
As the improvement of the utility model, a through hole below on the said housing is not installed and is cried.So, after the catch exposure is not installed the through hole that cries, extruding sounding chamber; Because the throughput of through hole is much larger than the throughput that cries; So gas flows out from the through hole in a large number, thereby, push the not purpose of sounding thereby reach from crying the effluent air quantity not sufficient to trigger reed.When the environment that needs peace and quiet, need toy not packed up, can be adjusted under the pattern of pushing sounding not, continue to use.Simultaneously, owing to be provided with this through hole, so improved the safety in utilization of air-flow sound-producing device.
As the further improvement of the utility model, also be provided with an independent catch on the said not through hole that device is named.So, sounding is accomplished by this independent catch with the control of sounding not, and utilizes other catch to play the purpose of optionally sending a certain or a few kinds of sound.
In sum, adopt technical scheme disclosed in the utility model after, reached selectivity sounding and sounding not, and selectivity is sent the purpose of a certain sound or a few kinds of sound.
