Abstract

The utility model discloses a sound-producing pipe type toy, belonging to sound-producing type toys. The utility model is composed of a pipe body and a whistle. Sound can be produced when the whistle falls from the top to down in the pipe. The sound-producing pipe is characterized in that the end caps of the both ends of the pipe body are provided with sound-producing holes; a film is arranged at the point of the end cap which is on one side of the inside of the pipe at the same time; the function of the film is used for ensuring the sound-producing holes on the lower end cap are covered to open the sound-producing pipe on the upper end cover when the sound-producing pipe is uprightness to make the whistler upwardly come out all along; in addition, a plurality of fine cotton threads are covered on the whistle body to improve the falling speed of the whistle to lower the knocking degree between the whistle and the end caps.

Description

Sound-producing pipe type toy

Pronunciation tube belongs to toy for children, relates in particular to a kind of sounding type toy.

The acoustic toy that a kind of being called " magic clave " once arranged on the toy market with its on vertical 180 ° when putting upside down back and forth, can send the sound, causes children's curiosity and interest with this.The barred body of this toy is the book wall pipe of hollow plastic, the whistle that a plastic cylinder is arranged in the pipe, the barred body two ends respectively have the end cap button, it is openend that one of them end cap has vocal hole, it is blind end that other end drowning has vocal hole, the sound of toy be by whistle in pipe when whereabouts air-flow the impact shock of beating reed is sent.The weak point of this toy is: when its blind end up the time, the sound that toy sends is to spread out of from down openend, the people sounds than a little less than the sound that upwards spreads out of, and especially just do not hear when noisy when environment has slightly, therefore allows the people take for one of a sound and do not ring; In addition, this toy requires whistle can free-falling in pipe, therefore when making in whistle external diameter and the hollow tubular through loose cooperating should be arranged, and the gap that this loose fit has often makes the whistle falling speed too fast, the time of sounding is too short, and falling speed causes the bump of whistle and end cap heavier, also damages whistle easily.

The purpose of this utility model provides a kind of two ends and all stays vocal hole and can improve whistle body and the pronunciation tube of pipe clearance conditions.

The utility model is achieved in that all produces vocal hole on the end cap at pronunciation tube two ends, simultaneously be positioned at the plastic sheeting that vocal hole that pipe one side setting can the opposite end covers is closed or opened in end caps; In addition, the some roads of cover have the cord circle of cilium on the body of the cylindrical whistle, and the very thin lousiness of coil can play the effect that reduces the gap but the free-falling that is not enough to stop whistle.

Pronunciation tube after the improvement, no matter that end up, birdie all only upwards spreads out of, the people can be heard distinctly all the time, and on the body of the whistle, put the fine rule circle, both need not improve craft precision such as mould and die accuracy, can slow down falling speed again and alleviate the degree of colliding with of the whistle and end cap, thus life-saving.

Concrete structure of the present utility model is seen the following drawings and embodiment.

Fig. 1 is the pronunciation tube overall schematic;

Fig. 2 is the membrane structure synoptic diagram;

Fig. 3 is the A-A view of Fig. 2.

Pronunciation tube is made up of the body that contains hollow tubular 1, end cap 2, film 3 and the whistle of containing whistle body 4, whistle hoop 5, whistle bone 6, beating reed 7, cord circle 8, end cap 2 is buckled in the blended rubber bonding jail, two ends of hollow tubular, on two end caps vocal hole 11 is arranged all, be positioned at pipe one side in end caps film 3 is set, film 3 is bigger than the area of vocal hole 11, and promptly film 3 can all cover vocal hole; Contain roundlet arc 9 and cutting 10 on the film 3, wherein little circular arc can be sandwiched between the end face and end cap of hollow tubular, perhaps directly sticks with glue on the plane that is positioned at pipe one side on the end cap; Cutting 10 is to open vocal hole when guarantee opening to greatest extent, and promptly easier that film was rolled over is sagging from cutting; Whistle body 4 is loaded in the pipe, puts cord circle 8 on the periphery of whistle body 4, and its quantity is 1～3 road, and fake can be the band of thin cotton thread, nylon wire or envelope curve, and the fine rule circle is to be enclosed within the groove that whistle body periphery makes in advance.

When playing this pronunciation tube, it is vertical, whistle free-falling under the deadweight effect in the pipe, at this moment the lower end film covers the vocal hole on the end cap, and the film of upper end is opened the vocal hole on the end cap, after whistle is fallen the bottom, pronunciation tube is turned around rapidly, whistle falls again from the top down, at this moment the unlatching vocal hole of the film that is positioned at the lower end when being in the upper end originally becomes closes vocal hole, the film that the is positioned at the upper end then sealing vocal hole when being in the lower end originally becomes and opens vocal hole, so pronunciation tube is put upside down back and forth, and its sound upwards spreads out of all the time.
