Description

[Detailed Description of the Invention] The present invention relates to an automobile speaker system that utilizes the directivity of a mid-to-high frequency speaker unit to vary the sound field characteristics of a vehicle interior.

Conventionally, automobile speakers have had their f-characteristics changed using Glyco or the like, or a small high-frequency speaker has been installed separately. however,
The former method cannot be expected to be very effective in changing the sound field, and the latter method has drawbacks such as the lack of flexibility in the space in which speakers can be installed, making it impossible to effectively change the sound field.

The present invention has been made in view of the above-mentioned circumstances, and includes a speaker for an automobile audio system in which a plurality of medium and high-frequency speakers are installed on different surfaces of the speaker cabinet, and the plurality of speakers are installed on separate surfaces of the speaker cabinet. To provide a speaker system for an automobile in which a controller to be used selectively is installed in a range where a driver's hand is bent so that a sound field inside the automobile can be varied as appropriate.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a speaker system showing an embodiment of the present invention, in which a main speaker 2 for a woofer is installed in a speaker cabinet 1, and a speaker 3A for medium and high frequencies is installed on a different side of the speaker cabinet 1. , 3B and 4A, 4B are installed respectively, and the above-mentioned mid-high sound speakers 3A, 3B and 4 are installed.
A controller 5 for selecting between A and 4B can be mounted at a position that is easy for the driver to operate.

FIG. 2 is a circuit diagram of the speaker system according to the present invention, which is a 3-way system with 2 squawkers and 2 tweeters.

That is, by selecting the middle and high frequency speakers 3A, 3B and 4A, 4B from the main speaker 2 using the controller 5, the speakers 3A, 4A side, 3B, 4B
A desired sound field is reproduced by the operation of the B side or a combination of both.

Note that the speakers 3A and 4A may be installed at the front of the speaker cabinet 1, and the speakers 3B and 4B may be installed at the rear of the speaker cabinet 1 to change the sound field inside the vehicle.

As explained in detail above, the automobile speaker system according to the present invention is configured so that the sound field and f-characteristics in the vehicle interior can be varied by using the directivity of the speaker unit for medium and high frequencies. This allows the listener to freely change and enjoy the music, and it is easy to operate.

Also, if there are passengers in the rear seats of the car, the high frequency range will be reduced, so please switch the speakers.
By reflecting the light off the rear window glass and ensuring f-characteristics, it is possible to control the increase or decrease in the number of occupants.

Furthermore, when combined with Glyco etc., it is possible to create an ideal sound field by performing AB cross operation etc. to obtain the best characteristics.
