In addition, front fender 13 and handlebar posts 21 also are the inscapes of the sound system of present embodiment, as shown in Figure 2, work as reflecting part, and having can be the sound that directive property is arranged that produces from control box 15 to occupant P function of reflecting.
Below, the effect of sound system with above-mentioned formation is described.
At first, with reference to Fig. 2 the effect of control box 15 is described.In control box 15, for the bass in the sound that produces by each loud speaker 41a, 41b, be exaggerated by Helmholtz's sympathetic response among space 51a, the 51b in front, a part becomes the lower part of the body of transfer of vibration to occupant P, and a part is passed slit 53a, 53b and passed to the outside.And for high pitch, change among space 51a, the 51b seldom in front, almost former state is passed slit and straight ahead forwards.At this moment, the sound that spreads out of from slit 53a, 53b has and the corresponding directive property of the interior shape (the particularly shape of leading space 51a, 51b and slit 53a, 53b) of control box 15.
At this moment, because each loud speaker 41a, 41b is configured to bass generating unit 43a as mentioned above, 43b near vehicle seat 16 (therefore, particularly concerning loud speaker 41b, bass generating unit 43b is towards the upper surface configuration of control box 15), and high pitch generating unit 44a, 44b is near ground, the bottom surface configuration of control box 15, so, each loud speaker 41a, in the sound that 41b produced, the major part of high pitch is advanced to the front direction of control box 15, the part of bass is delivered to occupant P as vibration, and another part of bass directly transmits to occupant P by the slit 53b of control box 15 upper surfaces.
Mainly the sound that spreads out of from the slit 53a of the front surface of control box 15 is reflected to occupant P by front fender 13 and handlebar posts 21.At this moment, front fender 13 and handlebar posts 21 will be passed the sound with directive property that slit 53a transmits in the direction reflection of keeping under the state of its directive property to occupant P.By making sound have such directive property, can make the sound that drains to vehicular sideview to reduce, thereby reduce noise.
Below, (effect of loud speaker 61a～61h) describes to the loudspeaker array that is provided with on the handle 22.As mentioned above, eight loud speaker 61a～61h be configured in with being the row shape respectively handle 22 on the surface of occupant P.That is to say that eight loud speaker 61a～61h are configured to make the direction of generating plane towards occupant P respectively, and be configured to bring into play the position relation of linear array effect.
At this, so-called linear array effect is meant the effect on the following sound equipment: sending from each loud speaker under the situation of synchronous sound, each interference of sound and form a kind of radiation state of sound appears to from the wire sound source.That is to say, under the situation of a loud speaker, hemispherical ground conduct acoustic waves, and relative with it, the situation of linear array loud speaker is next to be semicircle tubular ground conduct acoustic waves, so even in the place away from sound source, the decay of sound is also less.Therefore, as present embodiment, can bring into play eight loud speaker 61a～61h of linear array effect, even make the volume of turning each loud speaker 61a～61h down also can give occupant P with transmission sound by configuration on the handle 22 in occupant P the place ahead.
Again, in the present embodiment, each loud speaker 61a～61h is configured on the handle 22, but is not limited thereto, as long as can obtain effect same, can certainly adopt frame that beam is set and also dispose other formations such as loud speaker thereon.
On the axis direction (being the side surface direction of two-wheel electric vehicle 10) of handle 22, owing to the linear array effect makes interference of sound that each loud speaker 61a～61h produces and cancelling out each other, so sound dies down to the radiation of the side surface direction of two-wheel electric vehicle 10.That is to say that the sound of eight loud speaker 61a～61h generations has from the directive property of two-wheel electric vehicle 10 front portions towards the rear portion.Because of sound has this directive property, reduced the sound that drains to the side, thereby reduced noise.
Fig. 7 is the scheme drawing of an example of the sound space that formed by each loudspeaker assembly of expression.Utilization has the sound system of above-mentioned formation effect, as shown in Figure 7, has formed sound space 71 in the zone that surrounds occupant P.Particularly formed first sound space 72 by control box 15, front fender 13 and handlebar posts 21 comprising on vertical the direction of occupant P, (loud speaker 61a～61h) has formed second sound space 73 comprising on the horizontal surface direction of occupant P by being located at loudspeaker array on the handle 22.Sound space 71 forms by the sound space 72 of synthetic vertical direction and the sound space 73 of horizontal surface direction.
As mentioned above, according to present embodiment, below vehicle seat 16, be provided with control box 15 as first loudspeaker assembly, and handle 22 is provided with as the loudspeaker array of second loudspeaker assembly (loud speaker 61a～61h), the sound that will have directive property is concentrated to occupant P, in the zone that surrounds occupant P, formed sound space 71 thus, so the occupant can hear sound, on the other hand, because first loudspeaker assembly and second loudspeaker assembly only are created in the sound that has directive property on the vehicle fore-and-aft direction, so, can prevent that sound from draining to vehicular sideview and alleviating noise.That is to say, can reduce the sound around draining to and can provide necessary sound to the occupant.
Particularly be applied under the situation of elec. vehicle, motor is compared driving sound with driving engine little, need transmit operation information etc. to the occupant with sound, so it is respond well.
Wherein, carry out illustration with elec. vehicle as two-wheel car in the present embodiment, but be not limited thereto, also can be applicable to any two-wheel car.
