CN2146284Y - Pneumatic sound-producing means in toys - Google Patents

Abstract

The utility model relates to a pneumatic sound-producing device in a toy. A gravity slide block (9) which slides along a shaft direction is arranged inside an opening horn barrel (7) on one end, and a sound-producing source is carried by the gravity slide block (9). The sound-producing source comprises a diaphragm (5) and a whistle body (4). The sound-producing source and a whistle barrel (8) are fixed by a clamping hoop. The most of or the all parts and components of the pneumatic sound-producing device in a toy can use plastic products. The structure of the pneumatic sound-producing device in a toy is simple. The pneumatic sound-producing device in a toy can be arranged inside various dolls and small animals.

Description

Pneumatic sound-producing means in toys

The utility model relates to a kind of acoustical generator that is used for toy.

Toy is the requisite utensils of playing of children.It can develop child's intelligence.General toy stimulates children's sense organ with its various bodies and tone, most can not sounding, although minority can sound, but its complex structure, cost is higher, thereby price is also more expensive.

The utility model provides a kind of easy toy pneumatic acoustical generator.

This acoustical generator comprises the horn that an end is uncovered, and the gravity slide ball that slides is vertically arranged in it, and slide block carries sound generation source.

Sound generation source is fixed on the gravity slide ball by whistle tube, and sound generation source comprises diaphragm and whistle body, and whistle body is ship shape, and diaphragm covers on the body of the whistle, and whistle body open face is cylindrical.The logical clip of diaphragm and whistle body links together, and whistle tube is tightly withstood in the clip outside, and sound generation source is located in the tube of the whistle, and horn one end is provided with a grade muscle, stops its inner part slippage.

Further feature of the present utility model is most of or all parts can be made of plastic, and is in light weight, uses injection mo(u)lding, the production efficiency height.

Fig. 1 is a main cutaway view of the present utility model;

Fig. 2 is the vertical view of sound generation source part;

Fig. 3 is the transverse sectional view of sound generation source part.

With reference to the accompanying drawings, the utility model is described in further detail.

Horn shown in Figure 1 (7) is cylindrical, one end has end cap (10), seal, it must be tight fit, gravity slide ball (9) can vertically be free to slide at gravity effect lower edge horn (7) inwall, horn (7) other end is provided with end shelves muscle (1), links by end shelves (2) and horn (7), prevents gravity slide ball (9) slippage.The inner ring wall of gravity slide ball (9) blocks whistle tube (8) tightly, and it is whistle tube muscle (3) that its horn-like port end has the cross reinforcement.

As accompanying drawing 1,3, shown in, sound generation source comprises diaphragm (5) and whistle body (4), this part is fixing by clip (6) and whistle tube (8).Diaphragm (5) should use whippy plastic material to make.Because whistle body (4) open face is the face of cylinder, be labeled as R as accompanying drawing 1, so two ends are open-shaped in diaphragm (5), when gravity slide ball (9) move, air-flow impelled diaphragm to vibrate, send " toot " interesting sound.Certainly, along with the variation of diaphragm (5) size is different with hardness, the sound also can change.What will further specify here is in order diaphragm (5) effectively to be located on whistle body (4) is uncovered, can to adopt the complementary location of convex-concave, promptly making small embossment (11) (seeing accompanying drawing 2) on the body of the whistle, and make recess on diaphragm (5).

Acoustical generator of the present utility model can place in the toy of various need sounding, as doll, toy etc.Obviously, when profile was made a certain size, the utility model can become a kind of what is called " magic flute " separately.

Claims (6)

1, the pneumatic acoustical generator of a kind of toy is characterized in that, has the gravity slide ball (9) that slides vertically in the uncovered horn of an end (7), and gravity slide ball (9) inner ring carries sound generation source.

According to the described acoustical generator of claim 1, it is characterized in that 2, sound generation source is fixed on the gravity slide ball (9) by whistle tube (8).

According to the described acoustical generator of claim 2, it is characterized in that 3, sound generation source comprises diaphragm (5) and whistle body (4), whistle body (4) is ship shape, and diaphragm (5) covers on whistle body (4) is uncovered, the uncovered formation face of cylinder.

According to the described acoustical generator of claim 3, it is characterized in that 4, diaphragm (5) and whistle body (4) link together by clip (6), and whistle tube (8) is tightly withstood in the clip outside, and sound generation source is located in whistle tube (8).

According to the described acoustical generator of claim 1, it is characterized in that 5, horn (7) one ends are provided with a grade muscle (1), stop its inner part slippage.

According to the described acoustical generator of claim 1, it is characterized in that 6, the acoustical generator parts are most of or all use plastic production.
