Description

The environment protecting type engine noise is converted to music apparatus

The utility model relates to a kind of device that is installed at the engine exhaust pipe tail end and the tail gas noise is converted to musical sound.

In daily life, various engine exhaust noises (the especially corresponding noise of Motor Vehicle such as automobile, motorcycle) bring serious interference to people, and its befouling environment influences health.

The purpose of this utility model is, design the device that a kind of environment protecting type engine noise is converted to music, the noise that the tail gas from exhaust pipe of engine discharging can be produced is converted to musical sound, to eliminate its pollution to environment, and have simple in structure, the characteristics of beautiful shape.

The technical solution of the utility model is, it has cylindrical shell, its structural feature is, this cylindrical shell one end is uncovered and the other end has little cylindrical shell, there is slot the port both sides of described little cylindrical shell, and air communication is out-of-date to make its metal spring leaf that sends musical sound be plugged in the described slot and top is screwed on little cylindrical shell.

Make below in conjunction with accompanying drawing and to further specify.

Description of drawings; Fig. 1 is a front view, and Fig. 2 is a side view, and Fig. 3 is the partial component plan structure of device right-hand member among Fig. 2.In the drawings:

1-cylindrical shell, 5-metal spring leaf

2-slot, 6,8-screw,

3-little cylindrical shell, 7-iterative structure

4-collude and close structure 9-outlet pipe.

By accompanying drawing as can be known, the utility model has cylindrical shell (1), and its design feature is that cylindrical shell (1) one end is uncovered and for other One end has little cylindrical shell (3), and there is slot (2) the port both sides of this little cylindrical shell (3), air-flow by the time can make it send sound The metal spring leaf of music (5) is plugged in the described slot (2) and top is fixed on the little cylindrical shell (3) with screw (8). Figure 2 for the utility model device is socketed in the situation of the exhaust pipe of engine (9) tail end, so the shape of cylindrical shell (1) is not according to With exhaust pipe of engine tail end shape and decide, as shown in Figure 2 with the shape of tapering; Also can be cylindrical, Ellipse etc. In order to make this device conveniently be installed at securely exhaust pipe of engine tail end, cylindrical shell (1) can adopt Structure by left and right two parts combination shown in Figure 1, structure is closed in common colluding in the bottom employing this moment prior art (4) (being that hook connects), top is adopted iterative structure and is connected and fixed metal spring leaf (5) with screw (6) or bolt Adopt the prior art structure, get final product such as the reed structure in the mouth organ, this metal spring leaf (5) is to adopt copper reed as good. The applied engine of the utility model comprises various petrol engines, Diesel engine, steam turbine, steam engine etc. To dissimilar and engine model, adopt some model the utility model devices of different size to connect with it.

Operation principle of the present utility model is, exhaust pipe of engine tail end installs the utility model device (referring to Fig. 2) additional, When motor exhaust passes through metal spring leaf (5) from left to right, then impact reed and send musical sound, will start thus The noise of tail gas discharging is converted into musical sound, has eliminated the noise circumstance pollution, gives comfortable, melodious sense.

As known from the above, the utility model is the device that a kind of environment protecting type engine noise is converted to music, can will send out The noise that engine exhaust pipe exhaust emissions produces is converted to musical sound, eliminates the pollution of described Noise upon Environment, and knot Structure is simple, good looking appearance.

Embodiment: according to the utility model device of accompanying drawing and said structure, cylindrical shell (1) adopts thick 1 to 1.2 millimeter stainless steel materials to make, metal spring leaf (5) is used copper sheet, configurable by note 1,2,3,4,5,6,7 and high pitch thereof and bass totally two ten reeds, as required or hobby change to use, also can adopt compound note reed.Described device is installed at CG125 motorcycle engine outlet pipe tail end.

Claims (1)

1, a kind of environment protecting type engine noise is converted to music apparatus, cylindrical shell (1) is arranged, it is characterized in that, cylindrical shell (1) one end is uncovered and the other end has little cylindrical shell (3), there is slot (2) these little cylindrical shell (3) port both sides, and air communication is out-of-date to make its metal spring leaf that sends musical sound (5) be plugged in the described slot (2) and top is fixed on the little cylindrical shell (3) with screw (8).
