[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-way loudspeaker in which a tweeter is mounted on a woofer frame via a bridge, and more particularly to a means for improving the frequency characteristics.

[0002]

2. Description of the Related Art A conventional bridge type two-way speaker shown in FIG. 4 has a tweeter 1 mounted on a frame of a woofer 2 via a bridge 6. This two-way speaker has a drawback that the drive shaft of the tweeter 1 (the center axis in the sound emission direction) is not inclined, so that when mounted on the rear tray of a car, high frequency sounds are emitted upward and the directivity is poor. Was.

Further, as shown in FIG. 5, in a bridge in which the drive shaft of the tweeter is inclined, the direction of the boss 8 for attaching the bridge and the direction of the boss 7 for fixing the network are different from each other, so that the mold structure becomes complicated. there were.

[0004]

[Problems to be Solved by the Invention] This invention has been made in view of the above points, and its purpose is to radiate high-frequency sounds obliquely forward when mounted on a rear tray of a car. Accordingly, it is an object of the present invention to provide a two-way loudspeaker inclined bridge which improves the directivity.

Another object of the present invention is to provide an inclined bridge that can be formed by a conventional mold that does not use a slide mold.

[0006]

The inclined bridge of the two-way loudspeaker of the present invention extends over the woofer frame, and the boss for attaching the woofer frame is mounted on the inclined bridge in which the tweeter attachment panel surface is inclined with respect to the woofer drive shaft. The distance from the end surface to the panel surface is different between the left and right sides.

[0007]

According to the tilt bridge of the two-way loudspeaker of the present invention, when the bosses for mounting the right and left woofer frames are fastened to the same height position of the woofer frame, the panel surface of the tilt bridge is tilted and mounted there. The drive shaft of the tweeter tilts and high-frequency sounds are emitted obliquely forward.

Further, since the boss for attaching the woofer frame is perpendicular to the panel surface, even when the boss for fixing the network is provided on the panel surface perpendicular to the panel surface, the direction of the holes of all the bosses is the same. Therefore, molding can be performed without using a slide mold.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a two-way speaker according to an embodiment of the present invention. FIG. 1A is a side view showing an inclined bridge according to an embodiment of the present invention, and FIG. 1B is a bottom view showing the inclined bridge.

As shown in the figure, a hole 9 for mounting a tweeter is provided on the panel surface 3a of the inclined bridge 3.
Network board fixing bosses 7, 7 are provided on both sides of the panel surface 3a of the inclined bridge 3, and the network board 10 is fastened.

Below the inclined bridge 3, a pair of frame fixing bosses 8 and 8a are provided on both sides, and the distance between the end surface of the frame fixing boss 8 and the panel surface 3a and the end surface of the frame fixing boss 8a are provided. The distance from the panel surface 3a is different.

As shown in FIG. 2, the tweeter 1 is mounted on the woofer 2 using the inclined bridge 3 to make a two-way speaker. The inclined bridge 3 is fastened to the woofer frame 4, the details of which are shown in FIG.

As shown in FIG. 3, the woofer frame 4 is provided with an inclined portion having the same height, and the frame fixing bosses 8 and 8a are fastened to the holes provided therethrough by screws 5 and 5, respectively. . Accordingly, the panel surface 3a is inclined, and the drive shaft of the tweeter attached thereto is inclined to radiate high-frequency sounds obliquely forward.

Since the holes of the network board fixing boss 7 and the frame fixing bosses 8 and 8a have the same orientation, the inclined bridge 3 can be formed without using a slide mold.

[0015]

According to the tilt bridge of the two-way speaker of the present invention, the tweeter is mounted at an angle to the woofer, so that the directivity of high frequency sound is improved.

Further, since the mold structure of the inclined bridge does not become a slide type, the cost of the mold is reduced.
