Description

[Detailed description of the invention] [Technical field of the invention] This invention is based on installing a cabinet inside the door of a car, so that when the door is closed, the speaker cabinet attached to the dash board communicates with the cabinet inside the door. The present invention relates to a vehicle audio device.

[Technical background of the invention]

2. Description of the Related Art Conventionally, a cabinet containing a built-in speaker has been attached to the dashboard of an automobile, and the sound generated from the speaker is generated within the automobile.

[Problems with background technology]

However, as an automotive audio device, the ideal pipe-duct type cavity cannot be obtained by using only speakers attached to the dart board.

[Purpose of invention]

This invention was made to eliminate the above-mentioned conventional drawbacks, and aims to provide a vehicle acoustic device that provides an ideal pipe-duct type cavity and increases acoustic effects.

[Summary of the idea]

The vehicle audio system of this invention includes a first cabinet containing a built-in speaker attached to the dashboard of the vehicle, an opening provided on the side of the first gear cabinet, and a second cabinet buried within the front door of the vehicle. At the same time, a pipe duct that opens toward the interior of the car and a socket that connects to the opening of the first cabinet when the door is closed is installed on the side of the vehicle, and a part of the audio from the speaker is routed through the second cabinet to the pipe duct. It is designed to occur inside a car.

[Example of idea]

Embodiments of the vehicle acoustic device of this invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the configuration of one embodiment of the invention, showing a state in which the front door of the automobile is opened;
FIG. 2 shows the front door in a closed state.

In both FIGS. 1 and 2, reference numeral 1 denotes a speaker, which is housed in a relatively small cabinet 2. As shown in FIG. As shown, the cabinet 2 is attached to a dashboard 10 of an automobile. An opening 3 for the cabinet 2 is provided in the side surface of the cabinet 2 so as to pass through the side surface of the dash board 10. opening 3
is preferably made of rubber, but the material is not particularly limited.

On the other hand, a cabinet 4 is buried inside a front door 9 of the automobile. A socket 7 is provided on the side surface of the cabinet 4. This socket 7
It is also preferable to use rubber or the like. This socket 7
and the cabinet 4 are in communication, and when the front door 9 is closed, the opening 3 and the socket 7 are connected.

Furthermore, a pipe duct 5 is attached to the cabinet 4. This pipe duct 5 protrudes from the surface of the front door 9 and is directed into the automobile. Note that 6 is a door trim, and 8 is a window glass.

Next, the operation of the inventive vehicle audio system constructed as described above will be explained.

When the front door 9 is closed from the open state shown in FIG. 1 as shown in FIG. 2, the opening 3 of the cabinet 2 and the socket 7 of the cabinet 4 are connected.

This allows cabinet 2 and cabinet 4 to
are in a communication state, and part of the sound generated from the speaker 1 is generated from the front surface of the dash board 10, and is also generated from the pipe dart 5 via the opening 3, the socket 7, and the cabinet 4.

Therefore, the cabinet 4 is used as a cabinet for the speaker 1 attached to the dash board 10, and the pipe duct 5 also works effectively, so that the output sound pressure frequency characteristics as shown in FIG. 3 are obtained.

As is clear from FIG. 3, characteristic a is the frequency characteristic when only cabinet 2 is provided without cabinet 4 and pipe duct 5, whereas characteristic b is the frequency characteristic when cabinet 2, 4 and pipe duct 5 are provided. It can be seen that characteristic b has a longer bass range than characteristic a. Therefore, it can be seen that this idea is highly effective.

[Effect of idea]

As described above, according to the vehicle audio system of this invention, a cabinet is buried in the front door, and the cabinet with a built-in speaker and attached to the dash board communicates with the cabinet of the front door when the front door is closed. Since the sound from the speakers of the dart board is also output from the door, the cabinet of the dart board can be used effectively and the acoustic effect can be improved.

[Brief explanation of drawings]

FIG. 1 is a perspective view of an embodiment of the vehicle acoustic device of this invention with the front door open, FIG. 2 is a perspective view of the same vehicle acoustic device with the front door closed, and FIG. It is an output sound pressure frequency characteristic diagram of the vehicle audio device same as the above. 1... Speaker, 2, 4... Cabinet, 3
