Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to motorcycles, and in particular to speaker systems for motorcycles.

Prior Art and its Problems In a motorcycle equipped with a sound device such as a radio, one speaker is usually installed at almost both ends inside a fairing that surrounds the vehicle body from the front to both sides. For this reason, when there are two passengers, the rear seat passenger is located further away from the speaker than the front seat passenger (driver), and in addition, the sound generated by the speaker may be affected by the driver. There is a problem in that it is difficult to hear the sound coming from the speakers because the sound is somewhat blocked.

Therefore, it is desirable to install speakers at the rear of the vehicle so that passengers in the rear seats can easily hear the sound emitted from the speakers to the same extent as passengers in the front seats. Since the speaker is not provided with a speaker, there is a problem with where to install the speaker.

Means and Effects for Solving the Problems Therefore, in the present invention, in a motorcycle equipped with a front seat and a rear seat and a storage compartment arranged behind the rear seat, the center of the lid that covers the storage compartment from above is provided. A speaker is attached to an upper side of the lid so as to protrude laterally from a raised portion provided on the lid, and is arranged so as to be able to change its angle.

According to the present invention, by using the raised part provided on the lid of the storage compartment, the speaker can be placed close to the rear seat occupant without interfering with other members, and this speaker The mounting angle can be arbitrarily adjusted to suit the rear seat occupant.

Embodiments Hereinafter, the present invention will be described with reference to illustrated embodiments. FIG. 1 is a side view of a motorcycle to which the present invention is applied, and FIG. 2 is a top view thereof. This motorcycle includes a front seat 1 and a rear seat 2, and a backrest 3 is provided at the rear of the rear seat 2. Further, below the rear seat 2, side trunks 4, 4 are attached to the vehicle body frame on both sides of the vehicle body so as to partially cover the sides of the rear wheels 5, respectively. At the rear of the rear seat 2, a storage compartment 6 is provided extending from both sides of the backrest 3 to the rear, and is attached to the vehicle body frame. Pockets 8, 8 are provided on both front end surfaces of a lid 7 that covers the storage compartment 6 from above, respectively, and an armrest 9 is placed on the upper surface of the pocket 8.

A driver is seated astride the front seat 1 and operates the steering wheel 11 with his feet placed on the step 10. A fellow passenger similarly sits on the rear seat 2 and places his or her feet on the footrest 12, but can ride in a comfortable posture by leaning his back against the backrest 3 and resting his elbows on the armrests 9. The front part of the vehicle body is surrounded from the front side to both sides by a fairing 13, and front speakers 14, 14 are mounted on both sides of the inner surface of the fairing 13, as in a normal motorcycle equipped with a sound device. It is provided.

In this embodiment, in addition to the front speaker 14, left and right rear speakers 15, 15 are further provided. As mentioned above, the storage compartment 6 is provided extending from both sides of the backrest 3 to the rear, but in the center of the upper surface of the lid 7 there is a shape that supports the backrest 3 from behind, as shown in FIG. A raised portion 16 is formed in the rear speaker 15,
15 is attached to the outer end of a mounting shaft 17 that protrudes from the side 16a of the raised portion 16 and is spaced upward from the top surface 7a of the lid 7. The lid 7 is connected to the storage compartment 6 by a hinge (not shown) provided on the rear end surface.
The rear speaker 15 swings around the hinge to open and close, but at this time the rear speaker 15 also swings together with the lid 7 via the raised portion 16, so the rear speaker 15 does not interfere with the opening and closing operation of the lid 7. There's nothing to do.

As shown in FIG. 4, the mounting shaft 17 is provided with small diameter threaded parts 18 and 19 at both ends.
8 is inserted into the speaker box 20 of the rear speaker 15 and is fixed to the speaker box 20 by tightening with a nut 21. Mounting shaft 17
At the other end, a reduced diameter part 22 connected to the threaded part 19 is fitted into a hole provided in the side part 16a of the raised part 16, and a washer 23 is inserted into the threaded part 19 protruding inside the raised part 16. It is attached to the side portion 16a by screwing together a nut 24. The mounting shaft 17 can be rotated together with the speaker box 20 about its axis by applying a rotational force that overcomes the friction between the side portion 16a, the mounting shaft 17, and the washer 23, and in this way The mounting angle of the rear speaker 15 can be changed and adjusted as desired.

A speaker main body 25 is mounted inside the speaker box 20 by screwing the periphery of its cone 26 onto a mounting seat 27 protruding from the inner surface of the speaker box 20 with a screw 28. A lead wire 29 from the speaker body 25 is led out through an axial hole 30 provided in the mounting shaft 17, and is led out from the coupler 3.
1 to the harness 32. The harness 32 is connected to an audio device (not shown) disposed at a predetermined position on the vehicle body.

Figure 4a shows the speaker box 20 and the mounting shaft 17.
This shows a modification of the engaging portion. In this modification, the end surface 34 of the mounting shaft is formed into a spherical surface, and this end surface 34 is brought into contact with a similarly spherical concave surface 35 provided on the speaker box, and the spherical convex surface 35 on the opposite side
A saucer washer 37 is applied to 6 and pressed by the nut 21 via a spring 38. In this modification, the speaker box 20 can be rotated in any direction with respect to the mounting shaft 17, so that the orientation of the speaker can be freely changed not only in one direction but also in the vertical and horizontal directions.

FIG. 5 shows another embodiment of the invention. In this embodiment, the rear speaker 15 is a flexible tube 3.
3 to the base of the side part 16a of the raised part 16, and the mounting angle of the rear speaker 15 can be changed and adjusted with a greater degree of freedom than in the previous embodiment. The lead wire 29 is wired inside the flexible tube 33.

Effects of the Invention As described above, in the present invention, in a motorcycle equipped with a front seat and a rear seat and a storage compartment arranged behind the rear seat, a raised ridge provided in the center of a lid that covers the storage compartment from above is provided. Since the speaker is mounted above the side of the lid and is arranged so as to be able to change its angle, it is possible to arrange the speaker at a position close to the rear seat occupant without interfering with other members. Moreover, this speaker can be arbitrarily adjusted to a desired mounting angle to suit the rear seat occupant.
