Description

Speaker device of car

The present invention relates to a speaker device of an automobile, and more particularly, to an apparatus for providing improved sound by mounting a speaker to be rotatable on the interior ceiling of an automobile.

In general, automobiles are equipped with a radio function and an acoustic system for playing tapes and CDs, and the acoustic system is composed of amplifiers, decks, tuners, speakers, and the like.

The loudspeaker in the acoustic system is installed in place in the vehicle interior and constitutes one speaker device. In the related art, as shown in FIG. 1, one front speaker 1 mounted at each of the left and right sides of the front of the vehicle is provided with an instrument. It is installed in the panel 3.

Although not shown in FIG. 1, the speakers are also mounted on the left and right sides of the left and right doors and the rear magnets, respectively.

As shown in Figure 2, the structure of the speaker, the main frame 7 is fixed inside the main interior plate 5, including the instrument panel of the vehicle interior, the diameter of the main frame 7 toward the lower The narrowing funnel-shaped speaker frame 9 is fixed by the plurality of screws 11.

Below the speaker frame 9 is a magnetic circuit portion 17 composed of a second plate 12 having a first plate 10 and a shaft 11, a first magnet 14, and a second magnet 15. It is fixed.

A voice coil 22 is installed on the shaft rod 11 of the second plate 12 constituting the magnetic circuit part 17, and is supported by the speaker frame 9 as a damper 23 and has a funnel shape. The outer circumferential surface portion 20 is fixed along the circumference of the speaker frame 9.

The inner circumferential surface of the diaphragm 20 is fixed to the voice coil 22, and a plurality of holes are formed in the cover 24 adjacent to the speaker frame 9 so that sound is transmitted to the outside.

The operation of the speaker having the above configuration will be described with reference to the drawings.

When the acoustic system is operated, the voice signal current of the amplifier is input through the terminal board, and the input current is continuously input to the voice coil 22 shown in FIG. 2 through the signal supply line.

When the voice signal current is input to the voice coil 22 as described above, since the voice coil 22 is provided on the shaft 11 of the second plate 12 constituting the magnetic circuit part 17, the second magnet As the magnetic flux is generated in (15), the second plate 12 forms the N pole, and the first plate 10 forms the S pole as the magnetic flux is generated in the first magnet 14.

Accordingly, the first magnet 14, the second magnet 15, the first plate 10, and the second plate 12 form a magnetic circuit 17, and are input to the voice coil 22. Voice signal current flows into the magnetic circuit section 17.

Since the current flowing into the magnetic circuit part 17 generates a force by the left-hand rule of framing, the voice coil 22 vibrates up and down while preventing the left and right (see FIG. 2) vibrations by the damper 23.

The vibration plate 20 also vibrates by vibrating up and down of the voice coil 22, and thus, a sound is transmitted through air, which is a medium, and the sound is transmitted to the room through each hole formed in the cover 24. Spreads.

The speaker device of a conventional vehicle having the above-described configuration includes a front speaker 1 provided on the left and right sides of the instrument panel 3, a speaker provided on the door side, and a speaker provided on the rear magnet part.

However, the speaker device as described above does not satisfy the user's desire for high-quality sound, such as three-dimensional sound, it is required to further improve the speaker device.

And, it is necessary to adjust the position of the speaker by the change of the position of the occupant, the general speaker device is a fixed state is difficult to match the preferences of the consumer.
