The sound emitted by the directional sound generator 2 is generally a sound having a prompting, warning or guiding function, and may be, for example, no-pass, forward construction, lane change to the left/right, slow down, etc.

The power supply 3 is electrically connected with the directional sounder 2 so as to provide the directional sounder 2 with the electric energy required for its operation. In a preferred embodiment, the power supply 3 is an independent power supply such as a storage battery, a lithium battery pack or a rechargeable battery, preferably, the power supply can supplement electric energy through charging so as to prolong the service life of the power supply, and is more environment-friendly. In another preferred embodiment, the power supply 3 further has a plug and a power adapter, and the external power supply is directly used by connecting with the external power supply, and the solution described in this embodiment is suitable for use in a situation where the external power supply is easily available. Obviously, the power supply 3 may have both the independent power supply and the plug, so as to have the advantages of both, preferably, the external power supply can charge the independent power supply while using the external power supply.

It is easy to understand that, the directional road condition reminding device of the present invention can send out the reminding sound to the specific area by arranging the directional sound generator 2 on the road block 1, so as to remind the pedestrians and the drivers to pay attention to the road condition ahead. Because the propagation of its sound has directive property, consequently can not lead to the fact the interference to personnel outside the region, moreover, even under the condition of a plurality of directional reminding device of road conditions phonation simultaneously, as long as adjust them to the regional phonation of different orientation, the condition too noisy, that can not appear because hear a plurality of sounds simultaneously, the effect of its suggestion is better.

As a preferred embodiment, the directional sound generator 2 emits sound directionally by ultrasonic waves, as shown in fig. 3, and includes at least one ultrasonic transducer 20 and a signal generating module 21 electrically connected to the ultrasonic transducer 20. The signal generating module 21 includes a signal generating circuit 210 and a power amplifier 211, the power amplifier 211 is electrically connected to both the signal generating circuit 210 and the ultrasonic transducer 20, wherein the signal generating circuit 210 is configured to output a road condition prompting signal to the power amplifier 211, and the power amplifier 211 amplifies the road condition prompting signal to reach a driving voltage of the ultrasonic transducer 20, so that the ultrasonic transducer 20 directionally sends out an audio signal.

As another preferred embodiment, the directional sound generator 2 emits sound directionally through the speakers 22, as shown in fig. 4, in this embodiment, the directional sound generator 2 includes a plurality of speakers 22, and the plurality of speakers 22 form a speaker array 23 emitting sound toward the same area, which is preferably arranged in a linear array arrangement. The principle of directional sound production of a speaker array is as follows: when the acoustic generator generates sound, strong sound pressure can be generated in a specified direction (main lobe direction), and weak sound pressure can be generated in other directions (side lobe directions). The wave front of the loudspeaker array 23 is caused to propagate in a beam in a certain direction by coupling over the entire audio frequency range. By controlling the phase and amplitude of the input signals of each array element (namely, a loudspeaker) in the array, sound waves are enabled to be phonated and superposed in a designated place or direction, and phonation destructively interferes in other positions, so that directional sound transmission is realized.

The mounting position of the directional sound generator 2 is not limited, for example, as one possible embodiment, as shown in fig. 1 and 2, it is mounted on the outside of the barrier 1, for example, by being connected to the outer surface of the barrier 1 by means of bolts or snap connections or the like.

Fig. 10 shows the road block 1 in the form of a quadrangular pyramid, in which case the four outer surfaces 10 of the pyramid are each provided with a set of sound holes 11, so that the directional generator 2 can be rotated to four different directions to sound.

As shown in fig. 6 and 7, the directional road condition reminding device further includes a visual cue 4 disposed on the road block 1, and the visual cue 4 can give out a prompt message to further attract people's attention. In a possible embodiment, the visual cue 4 is a light strip, such as an LED light strip, which may form a direction cue such as an arrow to indicate to which direction the driver is driving; in another feasible implementation, the visual prompting object 4 is a prompting text, and directly warns or guides in the form of text, for example, the text can be a text such as no pass, slow speed and slow speed, and the prompting text can be formed by LED lamp beads, or pasted by a reflective material or displayed by a display screen, so as to achieve a more obvious prompting effect; in yet another possible embodiment, the visual cue 4 may be a reflective strip, which may be in the form of stripes of various colors, and can reflect the light of the vehicle at night, so as to attract the attention of the driver and make the driver safer. Obviously, the visual cue 4 is not limited to the above-mentioned example, and other ways of visually giving a cue may be applied to the barrier 1; additionally, one or more of the visual cues 4 described above may be applied simultaneously on the barrier 1.
