As shown in FIG. 2, an example of installation of an intake sound generator of a conventional vehicle is shown in FIG. As it enters the intake manifold (not shown) of the engine via the path 50, a part of the intake air flows out through the tuning pipe 30, and the pulsating pressure of the intake air generated in this process is a membrane (not shown). The vibration phenomenon occurs, the sound is generated according to the function to increase the sense of acceleration to the driver by implementing a sporty and powerful sound during the acceleration of the vehicle.

However, in the intake sound generator of the conventional vehicle, since the tuning pipe is located between the air cleaner and the intake manifold, the transmission loss of the entire intake system may be generated, which may cause unwanted intake discharge sound. Since there is a need to change the intake duct shape, there is a technical problem that an additional mold modification ratio is generated to increase the production cost.

The present invention is to solve the above problems, it is possible to maintain the shape of the intake duct of the vehicle engine as it is to prevent the production of additional mold modification costs to reduce the production cost, it is possible to prevent the fluctuation of the intake transmission loss, thereby preventing unwanted intake It is an object of the present invention to provide an intake sound generator for a vehicle that can prevent generation of discharge sounds.

The present invention is a membrane for generating an intake sound in accordance with the pulsating pressure; A bisected cover sandwiching both edges of the membrane; The cover is connected to one side, and the other side is achieved by configuring a tuning pipe coupled to the head cover to communicate with the engine inside the vehicle.

Here, the tuning pipe is preferably coupled to the oil inlet formed in the head cover of the engine.

In addition, the end of the tuning pipe and the oil inlet of the engine head cover is preferably formed with a coupling means that can be mutually coupled without a separate tool.

In the present invention, the coupling means may be made of a male screw and a female screw, and the coupling means may be made of a locking projection and a locking groove.

The present invention as described above can maintain the shape of the intake duct of the vehicle engine as it is, prevent the occurrence of additional mold modification ratio, reduce the production cost, and prevent the fluctuation of the intake transmission loss to prevent the occurrence of unwanted intake discharge sound It is an invention that can be made.

The intake sound generator of the vehicle of the present invention, as shown in Figure 3, the membrane 100 for generating the intake sound in accordance with the pulsating pressure; A bisected cover (200) sandwiching both edges of the membrane (100); The cover 200 is connected to one side, and the other side is composed of a tuning pipe 300 is coupled to the head cover 400 so as to communicate with the engine inside of the vehicle as a basic technical feature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, in the present invention, the membrane 100 vibrates according to the pulsation pressure of the engine to generate an intake sound, and the circular membrane 100 is illustrated.

Both edges of the membrane 100 are sandwiched between the covers 200 to be supported.

The cover 200 is coupled to one side of the elongated tuning pipe 300, and the other side of the tuning pipe 300 is coupled to and fixed to the head cover 400 so as to communicate with the engine of the vehicle. There is a big feature.

That is, in the related art, the tuning pipe 300 is connected between the air cleaner and the intake manifold of the engine, but in the present invention, the connection position of the tuning pipe 300 is the engine head cover 400.

As such, although a separate hole may be formed in the head cover 400 so as to communicate with the inside of the engine in order to connect the tuning pipe 300, in the present invention, the tuning pipe 300 is illustrated in the drawings. It is preferable to couple to the oil inlet 410 formed in the head cover 400 of the engine.

In addition, in the present invention, the end of the tuning pipe 300 and the oil inlet 410 of the engine head cover 400 is preferably formed with a coupling means that can be mutually coupled without a separate tool.

Through this coupling means, the operator can easily couple the tuning pipe 300 to the oil inlet 410 only by assembling and turning the tuning pipe 300 without a separate supply.

The coupling means as described above may be configured in various forms, but as shown in FIG. 4, the coupling means may include a male screw 310 and a female screw 411.

That is, a male screw 310 is formed at the outer periphery of the distal end of the tuning pipe 300, and an internal thread 411 formed corresponding to the oil cap 500 at the inner circumference of the oil inlet 410 of the engine head cover 400. Will be fixed and fastened.

Accordingly, by screwing the male screw 310 formed in the tuning pipe 300 to the female screw 411 formed in the oil inlet 410 to separate the oil cap 500 without a separate work tool, It can also be assembled by turning the intake sound generator.

Similarly, the coupling means may be made of a locking projection 320 and the locking groove 412 as illustrated in FIG.

In this case, the tuning pipe 300 is merely inserted into the locking protrusion 320 protruding on the outer circumference of the tuning pipe 300 into the locking groove 412 formed concave on the inner circumference of the oil inlet 410. It is also possible to easily assemble the oil inlet 410, there can be various embodiments in addition to this example will be apparent.

As such, since the position of the tuning pipe 300 is the oil inlet 410 of the engine head cover 400, the pulsation pressure is extracted from the front of the engine head cover 400, thereby reducing the flow in the intake manifold as well as the transmission loss of the entire intake system. It is an invention having a great advantage that can maintain the performance as it is to prevent the generation of unwanted intake discharge sound.

And, it is an invention that can reduce the production cost by preventing the additional mold correction ratio caused by the intake duct shape change as in the prior art.

In particular, the present invention also has the advantage that the tuning pipe 300 can be easily assembled without a separate tool.

The above embodiment is an example for explaining the technical idea of the present invention in detail, and the scope of the present invention is not limited to the above drawings or embodiments.
