Description

[Detailed Description of the Invention] Technical Field The present invention relates to a speaker device that is particularly suitable for use in so-called one-box or two-box automobiles, which are unsuitable for installing box-shaped speakers.

2. Background Art When installing a speaker device in an automobile, such as a one-box or two-box car, which is not suitable for installing a box-shaped speaker, the speaker body is embedded in the rear door, which has the advantage that the axis of the speaker body can be oriented toward the listener, making it easy to obtain a stereo sound. However, the volume inside the rear door is small, and therefore sufficient enclosure volume cannot be obtained. For this reason, the speaker body is actually installed on, for example, the side wall of the vehicle body. Therefore, the listening position is considerably inclined from the axis of the speaker body, which causes deviations in dips and peaks in the frequency characteristics, and the speaker bodies of the left and right channels are directly facing each other, making it difficult to obtain a stereo sound. In addition, when a box-shaped speaker is installed facing the listener using, for example, a bracket, the space inside the vehicle becomes narrow.

Problems to be Solved by the Invention The purpose of the invention is to provide a vehicle-mounted speaker device that can obtain sufficient enclosure capacity without sacrificing the interior space of the vehicle.

Means for Solving the Problems The present invention is characterized in that an outwardly protruding portion is provided at the rear of the vehicle body, and the speaker body is housed and installed in the interior space of the portion toward the interior of the vehicle. This is an in-vehicle speaker device.

According to the present invention, a portion protruding outward is formed on the rear of the vehicle body, for example, on the rear door. From the inside of the rear door, the speaker body is stored and attached in the internal space of the protruding portion so that it faces the interior of the vehicle.

As a result, the axis of the speaker body is directed toward the listener, and good sound reproduction with a stereo effect can be achieved. Further, the inside of the rear door including the interior space can be used as a speaker box, and sufficient enclosure capacity can be obtained without sacrificing the interior space of the vehicle. Furthermore, by using the protruding portion as a rear spoiler, for example, it is possible to improve the steering stability during high-speed running, and also to obtain an aesthetic appearance such as a feeling of lightness.

It is configured in the same way as . When the speaker devices 1a and 1b for both the left and right channels are collectively referred to, they are indicated by only the reference numeral 1.

In the speaker device 1 configured in this manner, the axis of the speaker body 13 faces toward the front of the vehicle compartment 3, that is, toward the listener. 1
3, the sound of both left and right channels will not interfere with each other, and the listening position will not be tilted from the axis of the speaker body 13, resulting in no caps or peaks in the frequency response. It is possible to perform good sound reproduction with a good feeling. In addition, the speaker body 13 is embedded in the protruding portion 9 of the rear door 2, and the internal volume of the rear door 2, including the internal space 12 of the protruding portion 9, is relatively large. Sufficient enclosure capacity can be obtained without sacrificing the interior space of the vehicle as would be the case if the present invention were installed. Furthermore, the protruding portion 9 has a function as a rear spoiler as described above, so that it is possible to improve the steering stability during high-speed running, and also to obtain an aesthetic appearance such as a feeling of lightness.
