  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

(Embodiment 1)
FIG. 1 is a diagram showing a traveling state of a two-wheeled vehicle, and a situation where a curve of R300 (radius of 300 meters) is approaching soon.

  In this R300, the maximum speed of the road is regulated to 80 km / h or less, for example, so that the two-wheeled driver tilts the vehicle body 1 to the right in FIG. 1 and 80 km / h or less (for example, regulation on a highway). I will drive in.

  For example, if this R300 continues for 1/4 lap, it takes 20 seconds or more to pass even if it is traveling at 80 km / h as described above. That is, the vehicle travels continuously for 20 seconds or more while tilted to the right.

  FIG. 2 shows a two-wheeled vehicle. A driver's seat 2 is provided at the center of the vehicle body 1, and a handle 4 is connected to the front wheel 3.

Further, a luggage storage unit 6 is disposed on the rear wheel 5.
In such a configuration, in the present embodiment, a front left speaker 7 is disposed on the front left side of the vehicle body 1, and a rear left speaker 8 is disposed on the front left side of the luggage storage unit 6 behind the vehicle body 1.

  Further, a front right speaker 9 is disposed on the front right side of the vehicle body 1, and a rear right speaker 10 is disposed on the front right side of the luggage storage unit 6 behind the vehicle body 1.

  FIG. 3 is a control block diagram of the two-wheeled vehicle sound reproducing device. The front left speaker 7 and the rear left speaker 8 are connected to an audio control unit 12 via an amplifier 11.

The front right speaker 9 and the rear right speaker 10 are connected to the audio control unit 12 via an amplifier 13.
Further, the audio control unit 12 is connected to a vehicle control unit 14, a reproduction unit 15, and a tilt detection unit 16 that detects the tilt of the vehicle body 1.

  That is, in this embodiment, when the two-wheeled vehicle driving is performed by the reproducing unit 15 while reproducing music, for example, as shown in FIG. 1, the music from the front left speaker 7 and the front right speaker 9 is in front of the vehicle body 1. Is reproduced in stereo, and in the rear of the vehicle body 1, music is reproduced in stereo from the rear left speaker 8 and rear right speaker 10, and driving while enjoying music in stereo can be performed.

  Even during such a two-wheeled vehicle operation, the inclination detection unit 16 in FIG. 2 always detects the inclination of the vehicle body 1 (S1 in FIG. 4).

  Specifically, as shown in FIG. 5, the tilt detection unit 16 according to the present embodiment does not detect the tilt itself as the tilt up to 10 degrees left and right is a dead zone, but when the vehicle body 1 tilts more than 10 degrees left and right, It is designed to detect which side is tilted to the left or right.

  Then, when the vehicle body 1 is tilted in excess of 10 degrees in either the left or right direction as described above, this is transmitted to the audio control unit 12, and as a result, the amplification degrees of the amplifiers 11 and 13 are controlled.

  For example, when the vehicle body 1 is tilted to the right, the amplification degree of the amplifier 13 on the inclined side is made smaller than the amplification degree of the amplifier 11, and as a result, outputs to the front right speaker 9 and the rear right speaker 10 are output. The output to the front left speaker 7 and the rear left speaker 8 is made smaller.

  This point will be explained in the situation of FIG. 1 described above. In the state of FIG. 1, for example, since it is a highway, it will enter R300 (radius 300 meters) at 80 km / h.

  At this time, although it depends on the speed, the vehicle body 1 travels in a state of tilting more than 10 degrees to the right in the R300.

  Therefore, the inclination detecting unit 16 detects that the vehicle body 1 is inclined by 10 degrees or more as described above, and then detects which side (left side or right side) the vehicle body 1 is inclined (S2, S3 in FIG. 4). .

  In FIG. 1, since the vehicle body 1 is tilted to the right side, the audio control unit 12 makes the amplification degree of the amplifier 13 on the inclined side smaller than the amplification degree of the amplifier 11 as described above. The output to the speaker 9 and the rear right speaker 10 is made smaller than the output to the front left speaker 7 and the rear left speaker 8 (S4 in FIG. 4).

  At this time, the driver is also tilted to the right side with the vehicle body 1 or more, so for the driver tilting to the right side, the left speaker (the front left speaker 7, the rear left speaker) The output balance of the speaker 8) and the right speaker (the front right speaker 9, the rear right speaker 10) is in a balanced state, and as a result, discomfort during curve driving can be eliminated.

  Of course, if the inclination of the vehicle body 1 at this time is the left side, the audio control unit 12 makes the amplification degree of the amplifier 11 on the inclined side smaller than the amplification degree of the amplifier 13, and as a result, the front left speaker 7, The output to the rear left speaker 8 is made smaller than the output to the front right speaker 9 and the rear right speaker 10 (S5 in FIG. 4).

  At this time, the driver is also tilted to the left side with the vehicle body 1 or more, so for the driver tilting to the left side in this way, the left speaker (the front left speaker 7, the rear left speaker) The output balance of the speaker 8) and the right speaker (the front right speaker 9, the rear right speaker 10) is in a balanced state, and as a result, discomfort during curve driving can be eliminated.

  When the inclination of the vehicle body 1 is not more than 10 degrees to the left and right, the detection by the inclination detector 16 is repeated (S6 in FIG. 4).

  In the above-described embodiment, when the vehicle body 1 is tilted, the left speaker (front left speaker 7 and rear left speaker 8) or right speaker (front right speaker 9, rear) on the tilt side of the vehicle body 1 is used. The output to the right speaker 10) is the right speaker (front right speaker 9, rear right speaker 10) or left speaker (front left speaker 7, rear left speaker 8) on the opposite side of the tilt side. ) Was made smaller than the output to.

  In the present invention, the left speaker (front left speaker 7 and rear left speaker 8) or the right speaker (front right side) on the tilt side of the vehicle body 1 is also provided by the audio control unit 12 or the amplifiers 11 and 13. The right speaker (front right speaker 9, rear right speaker 10) or left speaker (front left speaker 7) on the opposite side of the tilt side than the output to the speaker 9 for the rear and the rear right speaker 10). Further, by increasing the output to the rear left speaker 8), the output balance may be achieved, and as a result, the discomfort during traveling on the curve may be eliminated.

  As described above, in the present invention, when the inclination detecting unit detects that the inclination of the vehicle body is larger than a predetermined value, the audio control unit applies the left-side speaker or the right-side speaker to the vehicle body inclination side. Output is relatively smaller than the output to the right speaker or left speaker on the side opposite to the tilt side, so that the output balance between the left speaker and the right speaker is balanced. As a result, it is possible to eliminate the uncomfortable feeling during curve driving.

  Therefore, utilization as a sound reproduction device for a motorcycle is expected.
